It is also important to read all applicable CAUTION notes before the final selection. Use of catalog numbers when ordering will simplify and expedite the processing of your order. 1. Caution in selecting the mating 2. Caution in Selecting Based on Gear Strength 1 Basically, all spur gears, internal gears and racks can be paired as long as the module matches. with different materials, tooth widths, or methods of cutting the teeth can be mated. 2 When using a pinion with an internal gear with a small difference in the numbers of teeth, there are possibilities for involute interference, trochoid interference and trimming interference. See the internal gear interference portion of the technical section to avoid problems in assembling these items. (Page ) Calculation of Bending Strength of Item MSGA MSGB SSGS SSG SSS,SS,SSA SSY,SSAY SSAY/K SSR The gear strength values shown in the product pages were computed by assuming a certain application environment. Therefore, they should be used as reference only. We recommend that each user computes his own values by applying the actual usage conditions. Also, SUSL Fairloc hub spur gears, DSL Fairloc hub spur gears and SSAY/K spur gears with built-in clamps need additional considerations of the starting torque. The table below contains the assumptions established for various products in order to compute gear strengths.

NOTE 2 The allowable bending stress at the root σ Flim is calculated from JGMA01-01, and set to 2/3 of the value in the consideration of the use of planetary, idler, or other gear systems, loaded in both directions. NOTE 3 For SSG Ground, with module 0. or lesser, thermal refining is applied. Allowable bending stress and allowable hertz stress are referred to as the value shown in the parentheses. NOTE For SSS Pinion Shafts, with module over 1., tooth induction hardening is not applied. Allowable bending stress and allowable hertz stress are referred to the value shown in the parentheses. NOTE SSS Pinion Shafts with module 1.0 or lesser (SA configuration) are set to cantilever support as it is a single shaft type. BSS NSU PU PS PSA DSL DS Definition of bending strength by JGMA 01-01(197) The allowable bending strength of a gear is defined as the allowable tangential force at the pitch circle based on the mutually allowable root stress of two meshing gears under load. Definition of surface durability by JGMA 02-01(197) The surface durability of a gear is defined as the allowable tangential force at the pitch circle, which permits the force to be transmitted safely without incurring surface failure. Example of the failure due to insufficient bending strength. Example of the defacement due to insufficient surface durability. 31 Order from MARYLAND METRICS P.O.

If there are questions or if you require clarifications, please contact our technical department or your nearest distributor. KHK CO., LTD.

Therefore, use the bore for locating the center. If it is too difficult to do for small bores, the alternative is to use one spot on the bore and the runout of the side surface. 3 If the rework requires using scroll chucks, we recommend the use of new or rebored jaws for improved precision. If chucking by the teeth, please apply the pressure carefully to avoid crushing the teeth which will lead to noisy gears. Tapping & Keyway Slotting Lathe Operations The maximum bore size is dictated by the requirement that the strength of the hub is to be higher than that of the gear teeth. The maximum bore size should be 0% to 70% of the hub diameter (or teeth root diameter), and 0% to 0% for keyway applied modifications. In order to avoid stress concentration, leave radii on the keyway corners. Heat Treatment If you apply induction hardening to the gear teeth of SC products, you need to designate the hardness and where to apply the heat treatment. Below is an example of common specifications and KHK's specifications for hardening: Common Specifications for Heat Treatment Area: Tooth surface, or, Tooth surface and Tooth root Hardness: Within HRC in the range from to 0 HRC. (e.g. - HRC) KHK s Specifications for Heat Treatment Area: Tooth surface, or, Tooth surface and Tooth root Hardness: From 0 to 0 HRC. *Hardness and Depth of Gear-teeth Induction Hardening The hardening method and the state of hardened teeth area are varied depending on the size of gears. Since different hardening treatment is applied in accordance with the module and number of teeth, the hardness level you designate is referred to as the hardness of the reference diameter. For some of our products, there may be a case that the hardness at tooth tip / root may not be equal to the hardness you designated. As to the effective case depth for SC, it is specified by JIS, as The distance from the surface of the case to the area with hardness HV0. The case depth differs from area to area of a tooth. 2. Points of Caution in Assembling 1 KHK stock spur gears are designed to give the proper backlash when assembled using the center distance given by the formula below (center distance tolerance of H7 H). Backlash may be adjusted by changing the center distance of mating gears. For more information, please consult the technical section on gear backlash (page ) in separate technical reference book. 32 To avoid problems of reduced gear precision and other manufacturing difficulties, do not attempt to machine the gears to reduce face widths. 7 If you apply induction hardening on gear teeth, please be aware of potential thermal stress cracks. Also, note that the precision grade of the product declines by 1 or 2 grades, as deformation on material may occur. If you require tolerance for bore or other parts, machining is necessary after heat treatment. a = m(z1+z2)/2 where a :Center Distance m :Module Z1 :No. of teeth of pinion Z2 :No. of teeth of gear Order from MARYLAND METRICS P.O.

Please refer to this data when designing gear boxes or other components. Overall Length Tolerance for and Overall Length(mm) Under Over Under 0 Over 0 Tolerance 0-0. 0-0.1 0-0. Note Following products are excluded from this table: pinion shafts, Injection molded spur gears, Fairloc hub spur gears, and MC nylon products. 3 gears produce no thrust forces, however, be sure to fasten them firmly with stepped shafts, or collars, to prevent shifting toward the shaft. Keyways are generally used in fastening gears to a shaft, and they should be secured by applying drilled holes for set screws, or applying flats to the shaft, in case of fastening only with set screws. There are also methods of secure settings using a MACHALOCK, a Posi-Lock, or a Shupanring, which are parts for the engaging the hole and the axis. Verify that the two shafts are parallel. Incorrect assembly will lead to uneven teeth contact which will cause noise and wear. (After assembly, the gear mesh can be checked by applying a contact pattern compound and rotating the gears.) Test example: Abrasion occurred on SSG3- due to poor edge contact (only % with proper contact). In this example, the gear oil used is equivalent to the JIS gear oil category 2, No. 3 The design conditions were load torque at 27 rpm, 2. kg/m ( kw), 1. times the allowable bending strength, and 3 times the allowable surface durability torque. The pitting occurred on the poor tooth contact area after 0 hours of Poor tooth contact and pitting continuous operation. Application Examples Full-automatic Forming Machine by Jey Machine Co. SSA and SS are used for stirring devices. Takashima High-Speed Wire Straightening & Cutting Machines by Takashima Sangyo Co., Ltd. SS are used at the feeder. Automatic Packing Machine by New Max SS, segment shaped by secondary operation, are used at the crimping device. Electric Wire Winder by Sakuma Tekko KK. SS are used at the stopper of handgrip. 33 Order from MARYLAND METRICS P.O.

KHK Quick-Mod, the KHK's system for quick modification of KHK stock gears is also available. 2 Due to the gear teeth being induction hardened, no secondary operations can be performed on tooth areas including the bottom land (approx. 2 to 3 mm). Poor tooth contact occurred on SSG3- (Approx. % of the proper gear contact) Gear Oil (Equivalent to JIS gear oil category 2 and No. 3) The design conditions are load torque at 27 rpm, of N m ( kw), 1. times the allowable bending strength, and 3 times the allowable surface durability torque. The pitting occurs on the poor tooth contact area after only 0 hours of continuous operation. 1 Order from MARYLAND METRICS P.O.

How does the K-Clamp work? The K-Clamp uses a crescent shaped piece, appropriate for the size of the shaft as the pressure wedge to secure the gear on the shaft. Shaft Hexagonal Socket Head Crescent Shaped Pressure Wedge Application Hints 1. The slipping torque is affected by the fitting and clamping surface conditions. Remove as much lubricant as possible, and use the same size shaft as the bore, within h7 tolerances. 2. K-Clamp gears are suitable for relatively small gears in light loads with the bore size ranging between φ and φ mm. The gear will slip on the shaft when the actual load exceeds the slipping torque. The use of a key in addition to the K-Clamp is recommended for heavier loads or large bores sizes. 9 Order from MARYLAND METRICS P.O.

Recommended shaft tolerances are g, h and h7. Torque slippage should be considered when making a selection. Do not tighten the clamping screw without inserting a shaft, or the bore will be permanently deformed and will not accept a shaft The following products are gear press-fitted into a hub : SUSL0. with 9 teeth or more, SUSL0. with 0 teeth or more. Also, some of the hubs might slightly differ in shape as shown in the diagram. Fastening torque vs. Slipping torque The slipping torque which is dependent on the fastening torque can sometimes be less than the gear strength. Please use caution in selecting. The chart on the right shows the relationship between the slipping torque and the fastening torque. * The gear grade listed is the value before clamping.
