8 1. Rolling beaing stuctues and types 1-1 Stuctue Rolling beaings (beaings heeinafte) nomally compise beaing ings, olling elements and a cage (see Fig. 1-1). Rolling elements ae aanged between inne and oute ings with a cage, which etains the olling elements in coect elative position, so they do not touch one anothe. With this stuctue, a smooth olling motion is ealized duing opeation. Beaings ae classified as follows, by the numbe of ows of olling elements: singleow, double-ow, o multi-ow (tiple- o fouow) beaings. Oute ing Ball Inne ing Cage Cup Rolle Cone Cage 2) Rolling element Rolling elements may be eithe balls o olles. Many types of beaings with vaious shapes of olles ae available. Ball Cylindical olle (L w 3D w ) 1) Long cylindical olle (3D w < L w <10D w, D w > 5 mm) 1) Needle olle (3D w < L w <10D w, D w 5 mm) 1) Tapeed olle (tapeed tapezoid) Convex olle (bael shape) Note 1) L w : olle length D w : olle diamete 3) Cage The cage guides the olling elements along the beaing ings, etaining the olling elements in coect elative position. Thee ae vaious types of cages including pessed, machined, molded, and pin type cages. Due to lowe fiction esistance than that found in full complement olle and ball beaings, beaings with a cage ae moe suitable fo use unde high speed otation. Deep goove ball beaing Tapeed olle beaing Shaft washe Ball Housing washe 1-2 Type The contact angle (α) is the angle fomed by the diection of the load applied to the beaing ings and olling elements, and a plan pependicula to the shaft cente, when the beaing is loaded. Thust ball beaing Cage Note) In thust beaings inne and oute ings and also called "shaft washe" and "housing washe" espectively; in tapeed olle beaings, the espective foms ae "cone" and "cup." Fig. 1-1 Beaing stuctue 1) Beaing ings The path of the olling elements is called the aceway; and, the section of the beaing ings whee the elements oll is called the aceway suface. In the case of ball beaings, since gooves ae povided fo the balls, they ae also efeed to as aceway gooves. The inne ing is nomally engaged with a shaft; and, the oute ing with a housing. α = 0 α α = 90 Beaings ae classified into two types in accodance with the contact angle (α). Radial beaings (0 α 45 )... designed to accommodate mainly adial load. Thust beaings (45 < α 90 )... designed to accommodate mainly axial load. Rolling beaings ae classified in Fig. 1-2, and chaacteistics of each beaing type ae descibed in Tables 1-1 to 1-8. A 1

29 4. Handling of beaings 4. Handling of beaings 4-1 Geneal instuctions Since olling beaings ae moe pecisely made than othe machine pats, caeful handling is absolutely necessay. 1) Keep beaings and the opeating envionment clean. 2) Handle caefully. Beaings can be cacked and binelled easily by stong impact if handled oughly. 3) Handle using the pope tools. 4) Keep beaings well potected fom ust. Do not handle beaings in high humidity. Opeatos should wea gloves in ode not to soil beaings with pespiation fom thei hands. 5) Beaings should be handled by expeienced o well tained opeatos. 6) Set beaing opeation standads and follow them. Stoage of beaings Cleaning of beaings and thei adjoining pats Inspection of dimensions of adjoining pats and finish conditions Mounting Inspection afte mounting Dismounting Maintenance and inspection (peiodical inspection) Replenishment of lubicants 4-2 Stoage of beaings In shipping beaings, since they ae coveed with pope anti-coosion oil and ae wapped in antitanish pape, the quality of the beaings is guaanteed as long as the wapping pape is not damaged. If beaings ae to be stoed fo a long time, it is advisable that the beaings be stoed on shelves set highe than 30 cm fom the floo, at a humidity less than 65%, and at a tempeatue aound 20 C. Avoid stoage in places exposed diectly to the sun's ays o placing boxes of beaings against cold walls. 4-3 Beaing mounting Recommended pepaation pio to mounting 1) Pepaation of beaings Wait until just befoe mounting befoe emoving the beaings fom thei packaging to pevent contamination and ust. Since the anti-coosion oil coveing beaings is a highly capable lubicant, the oil should not be cleaned off if the beaings ae pe-lubicated, o when the beaings ae used fo nomal opeation. Howeve, if the beaings ae used in measuing instuments o at high otation speed, the anti-coosion oil should be emoved using a clean detegent oil. Afte emoval of the anti-coosion oil, beaings should not be left fo a long time because they ust easily. 2) Inspection of shafts and housings Clean up the shaft and housing to check whethe it has flaws o bus as a esult of machining. Be vey caeful to completely emove lapping agents (SiC, Al 2 O 3, etc.), casting sands, and chips fom inside the housing. Next, check that the dimensions, foms, and finish conditions of the shaft and the housing ae accuate to those specified on the dawing. The shaft diamete and housing boe diamete should de measued at the seveal points as shown in Fig. 4-1 and 4-2. Fig. 4-1 Measuing points on shaft diamete Fig. 4-2 Measuing points on housing boe diamete Futhemoe, fillet adius of shaft and housing, and the squaeness of shouldes should be checked. When using shaft and housing which have passed inspection, it is advisable to apply machine oil to each fitting suface just befoe mounting. A 22

30 4-3-2 Beaing mounting Mounting pocedues depend on the type and fitting conditions of beaings. Fo geneal beaings in which the shaft otates, an intefeence fit is applied to inne ings, while a cleaance fit is applied to oute ings. Fo beaings in which the oute ings otate, an intefeence fit is applied to the oute ings. Intefeence fitting is oughly classified as shown hee.

32 Table 4-2 Shink fit of cylindical boe beaings Shink fit Themomete Desciptions This method, which expands beaings by heating them in oil, has the advantage of not applying too much foce to beaings and taking only a shot time. (a) Heating in an oil bath (Notes) Oil tempeatue should not be highe than 100 C, because beaings heated at highe than 120 C lose hadness. Heating tempeatue can be detemined fom the boe diamete of a beaing and the intefeence by efeing to Fig Use nets o a lifting device to pevent the beaing fom esting diectly on the bottom of the oil containe. Since beaings shink in the adial diection as well as the axial diection while cooling down, fix the inne ing and shaft shoulde tightly with the shaft nut befoe shinking, so that no space is left between them. (b) Induction heate This photogaph shows a special machine fo fitting the inne ings of cylindi- olle beaings. cal Shink fit poves to be clean and effective since, by this method, the ing can be povided with even heat in a shot time using neithe fie no oil. When electicity is being conducted, the beaing itself geneates heat by its electical esistance, aided by the built-in exciting coil. Fo cylindical olle beaings used in oll necks of olling mills and ailway olling stock axle jounals, whee ings ae fequently mounted and dismounted, it is advisable fo ESE special induction heates (with automatic demagnetizes) to be used to fit inne ings.

Thick solid lines show the maximum intefeence value between beaings (class 0) and shafts (6, p6, n6, m5, k5, js5) at nomal tempeatue. 2. Theefoe, the heating tempeatue should be selected to gain a lage "expansion of the boe diamete" than the maximum intefeence velues. When fitting class 0 beaings having a 90 mm boe diamete to m 5 shafts, this figue shows that heating tempeatue should be 40 C highe than oom tempeatue to poduce expansion lage than the maximum intefeence value of 48 µm. Howeve, taking cooling duing mounting into consideation, the tempeatue should be set 20 to 30 C highe than the tempeatue initially equied. A 25

Handling of beaings Table 4-3 Mounting beaings with tapeed boes Mounting methods Desciptions When mounting beaings diectly on tapeed shafts, povide oil holes and gooves on the shaft and inject high pessue oil into the space between the fitting sufaces (oil injection). Such oil injection can educe tightening toque of locknut by lessening fiction between the fitting sufaces. When exact positioning is equied in mounting a beaing on a shaft with no shoulde, use a clamp to help detemine the position of the beaing. q Locknut w Hydaulic nut (a) Mounting on tapeed shafts Locating beaing by use of a clamp q Locknut w Hydaulic nut (b) Mounting by use of an adapte When mounting beaings on shafts, locknuts ae geneally used. Special spannes ae used to tighten them. Beaings can also be mounted using hydaulic nuts. Special spanne When mounting tapeed boe spheical olle beaings, the eduction in the adial intenal cleaance which gadually occus duing opeation should be taken into consideation as well as the push-in depth descibed in Table 4-4. q Locknut w Hydaulic nut (c) Mounting by use of a withdawal sleeve e e Cleaance eduction can be measued by a thickness gage. Fist, stabilize the olle in the pope position and then inset the gage into the space between the olles and the oute ing. Be caeful that the cleaance between both olle ows and the oute ings is oughly the same (e e ). Since the cleaance may diffe at diffeent measuing points, take measuements at seveal positions. When mounting self-aligning ball beaings, leave enough cleaance to allow easy aligning of the oute ing. (d) Measuing cleaances A 26

In mounting beaings with C3 cleaance, the maximum value listed above should be taken as the standad. 4-4 Test un A tial opeation is conducted to insue that the beaings ae popely mounted. In the case of compact machines, otation may be checked by manual opeation at fist. If no abnomalities, such as those descibed below, ae obseved, then futhe tial opeation poceeds using a powe souce. Knocking... due to flaws o insetion of foeign matte on olling contact sufaces. Excessive toque (heavy)... due to fiction on sealing devices, too small cleaances, and mounting eos. Uneven unning toque... due to impope mounting and mounting eos. Fo machines too lage to allow manual opeation, idle unning is pefomed by tuning off the powe souce immediately afte tuning it on. Befoe stating powe opeation, it must be confimed that beaings otate smoothly without any abnomal vibation and noise. A 27

35 4. Handling of beaings Powe opeation should be stated unde no load and at low speed, then the speed is gadually inceased until the designed speed is eached. Duing powe opeation, check the noise, incease in tempeatue and vibation. If any of the abnomalities listed in Tables 4-5 and 4-6 ae found, opaation must be stopped, and inspection fo defects immediately conducted. The beaings should be dismounted if necessay.

In geneal, beaing tempeatue can be estimated fom housing tempeatue, but the most accuate method is to measue the tempeatue of oute ings diectly via lubication holes. Nomally, beaing tempeatue begins to ise gadually when opeation is just stating; and, unless the beaing has some abnomality, the tempeatue stabilizes within one o two hous. Theefoe, a apid ise in tempeatue o unusually high tempeatue indicates some abnomality. A 28

36 4-5 Beaing dismounting Afte dismounting beaings, handling of the beaings and the vaious methods available fo this should be consideed. If the beaing is to be disposed of, any simple method such as toch cutting can be employed. If the beaing is to be eused o checked fo the causes of its failue, the same amount of cae as in mounting should be taken in dismounting so as not to damage the beaing and othe pats. Since beaings with intefeence fits ae easily damaged duing dismounting, measues to pevent damage duing dismounting must be incopoated into the design. It is ecommended that dismounting devices be designed and manufactued, if necessay. It is useful fo discoveing the causes of failues when the conditions of beaings, including mounting diection and location, ae ecoded pio to dismounting. Dismounting method Tables 4-7 to 4-9 descibe dismounting methods fo intefeence fit beaings intended fo euse o fo failue analysis. The foce necessay to emove beaings can be calculated using the equations given on page A 23. Table 4-7 Dismounting of cylindical boe beaings Fixtues Inne ing dismounting methods (a) Dismounting by use of a pess Desciptions Non-sepaable beaings should be teated caefully duing dismounting so as to minimize extenal foce, which affects thei olling elements. The easiest way to emove beaings is by using a pess as shown in Fig.(a). It is ecommended that the fixtue be pepaed so that the inne ing can eceive the emoval foce. Figs.(b) and (c) show a dismounting method in which special tools ae employed. In both cases, the jaws of the tool should fimly hold the side of the inne ing. (b) Dismounting by use of special tools Removal jaws (c) Dismounting by use of special tools Fig.(d) shows an example of emoval by use of an induction heate: this method can be adapted to both mounting and dismounting of the inne ings of NU and NJ type cylindical olle beaings.

Handling of beaings Table 4-8 Dismounting tapeed boe beaings (a) Dismounting by use of a wedge Inne ing dismounting methods (b) Dismounting by use of oil pessue Desciptions Fig.(a) shows the dismounting of an inne ing by means of diving wedges into notches at the back of the labyinth. Fig.(b) shows dismounting by means of feeding high pessue oil to the fitting sufaces. In both cases, it is ecommended that a stoppe (ex. shaft nuts) be povided to pevent beaings fom suddenly dopping out. Fo beaings with an adapte sleeve, the following two methods ae suitable. As shown in Fig.(c), fix beaings with clamps, loosen locknuts, then hamme off the adapte sleeve. This method is mainly used fo small size beaings. Fig.(d) shows the method using hydaulic nuts. (c) Dismounting by use of clamps (d) Dismounting by use of hydaulic nuts Small size beaings with withdawal sleeves can be emoved by tightening locknuts as shown in Fig.(e). Fo lage size beaings, povide seveal bolt holes on locknuts as shown in Fig.(f), and tighten bolts. The beaings can then be emoved as easily as small size beaings.

38 4-6 Maintenance and inspection of beaings Peiodic and thoough maintenance and inspection ae indispensable to dawing full pefomance fom beaings and lengthening thei useful life. Besides, pevention of accidents and down time by ealy detection of failues though maintenance and inspection geatly contibutes to the enhancement of poductivity and pofitability Cleaning Befoe dismounting a beaing fo inspection, ecod the physical condition of the beaing, including taking photogaphs. Cleaning should be done afte checking the amount of emaining lubicant and collecting lubicant as a sample fo examination. A dity beaing should be cleaned using two cleaning pocesses, such as ough cleaning and finish cleaning. It is ecommended that a net be set on the bottom of cleaning containes. In ough cleaning, use bushes to emove gease and dit. Beaings should be handled caefully. Note that aceway sufaces may be damaged by foeign matte, if beaings ae otated in cleaning oil. Duing finish cleaning, clean beaings caefully by otating them slowly in cleaning oil. In geneal, neutal wate-fee light oil o keosene is used to clean beaings, a wam alkali solution can also be used if necessay. In any case, it is essential to keep oil clean by filteing it pio to cleaning. Apply anti-coosion oil o ust peventive gease on beaings immediately afte cleaning Inspection and analysis Befoe detemining that dismounted beaings will be eused, the accuacy of thei dimensions and unning, intenal cleaance, fitting sufaces, aceways, olling contact sufaces, cages and seals must be caefully examined, so as to confim that no abnomality is pesent. It is desiable fo skilled pesons who have sufficient knowledge of beaings to make decisions on the euse of beaings. Citeia fo euse diffes accoding to the pefomance and impotance of machines and inspection fequency. If the following defects ae found, eplace the beaing with a new one. Cacks and chips in beaing components Flaking on the aceway sufaces and the olling contact sufaces Othe failues of a seious degee 4-7 Methods of analyzing beaing failues It is impotant fo enhancing poductivity and pofitability, as well as fo accident pevention that abnomalities in beaings ae detected duing opeation. Repesentative detection methods ae descibed in the following section. 1) Noise checking Since the detection of abnomalities in beaings fom noises equies ample expeience, sufficient taining must be given to inspectos. Given this, it is ecommended that specific pesons be assigned to this wok in ode to gain this expeience. Attaching heaing aids o listening ods on housings is effective fo detecting beaing noise. 2) Checking of opeating tempeatue Since this method utilizes change in opeating tempeatue, its application is limited to elatively stable opeations. Fo detection, opeating tempeatues must be continuously ecoded. If abnomalities occu in beaings, opeating tempeatue not only incease but also change iegulaly. It is ecommended that this method be employed togethe with noise checking. 3) Lubicant checking This method detects abnomalities fom the foeign matte, including dit and metallic powde, in lubicants collected as samples. This method is ecommended fo inspection of beaings which cannot be checked by close visual inspection, and lage size beaings. A 31
