1 Precision lock nut Hydraulic nut Wedge block WBK bearing seat

2 Locking device The locking device applied by the precision bearing to axially position on the shaft would be manufactured with high precision. The standard lock nut with lock washer is not suitable for the precision bearing because there is relatively large manufacturing tolerance between its thread and supporting surface, which may lead to shaft deformation and changes of rotary shaft. The lock nut of precision bearing should provide uniform support on the entire inner periphery to avoid shaft deformation (especially under the condition of heavy preload). They should also be easy to install and remove. To meet demanding requirements of the application of machine tool from the technical and economical perspectives, Jiangsu Swift Machinery Technology Co.,Ltd has developed a precision lock nut with high cost performance.

4 Locking device Multiple designs Jiangsu Swift Machinery Technology Co.,Ltd can manufacture multiple types of precision lock nuts with lock-pin. Here we illustrate two types: R-type and F-type. With two kinds of such nuts, bearings can be easily and reliably axially positioned on the shaft with other parts with high precision. Their specialty is three phosphor bronze lock pins uniformly distributed along the periphery. These pins are fixed on the screw thread of the shaft by inner hexagonal flat screws to prevent rotation of the nuts. Both the installation and design are simple, without extra lock washer or groove on the shaft. The lock pin and flat screw keep an angle with the axis the same as that of the thread surface. The end of lock nut is processed in the same process with that of the thread, so it also features thread form. The nut is locked in place completely relying on the friction between the lock pin and axial thread as well as the cohesive frictions between thread surfaces. Therefore, the lock pin cannot bear the axial load forced on the nut. Once the nut is locked, the thread surface will not release axial load and the nut will not be deformed (Figure1). Another advantage of F-type nut is that it can be adjusted. Three lock nuts with equal spaces can precisely position the nut, keep it perpendicular to the shaft. The lock pin can also be used to correct the inaccuracy and deviations of other parts to be installed on the shaft. Due to that the lock pin will not be changed in the form, R-type and F-type nuts can ensure their precision even after multiple assembly and dis-assembly. Figure 2 displays an application case for F-type lock nut. Figure 1 Figure 2 Figure 3 Major data Tolerance Screw thread is manufactured according to 4H precision with 4H tolerance and vertical precision of 0.005mm. Material Lock nut is made of high-rigid steel (42CrMo), with rigidity of HRC28 32 ; its surface is coated with phosphate and lubricated. Lock pin applies phosphor bronze. Flat screw is 12.9-grade bolt with high-strength. Installation It is quite easy to install R-type and F-type lock nuts. There are grooves around the periphery. Select wrenches of different types according to applications and size of nuts, including claw wrench and impact wrench (Figure 3). Product list has shown the corresponding sizes for wrenches and keys (for flat screw). In order to securely lock the R-type or F-type lock nut, please firstly tighten the flat screw slightly until the thread of lock pin is matched with the thread of the shaft. Then alternatively and evenly screw up the flat screws tightly until the tightening torque shown in the product list is reached. Please correct the misalignment between the supporting surface of the thread with the components nearby. Firstly, loosen the flat screw in a place with the maximum deviation and tighten the other two screws to the same extent. Then remove the loosened screw. If the required precision has not been reached, repeat the above steps until it is perfectly corrected. Dis-assembly In dis-assembling the R-type or F-type lock nut, please ensure that the lock pin is meshed with the thread of the shaft. Hitting the nut slightly in the vicinity of the flat screw by rubber hammer can loosen the lock pin, which can help to easily take the nut off the thread of the shaft.

6 Precision lock nut SWT/R series The locking method of SWT/R series is axial three-point locking. With thinner thickness, it is suitable for the installation environment which is restricted in the thickness. Because lock copper is perpendicular to the male screw thread in axial locking, over-large tightening torque of lock copper may easily lessen the axial load of the nut.

24 Wedge block 30 /15 /8 series SWIFT Wedge block Nowadays, the wedge blocks of the line rail manufactured by machinery manufacturers through procedures, such as milling and drilling, are different in sizes due to that single clamping cannot be realized for the manufacturing procedures. Likewise, due to small demands and dispersed applications, the manufacturing cost of the wedge block remains at a relatively high level. Jiangsu Swift Machinery Technology Co.,Ltd applies powder metallurgy and high-precision to produce the wedge block with only a single punching. The mass production has effectively reduce the cost and the manufacturing process has guaranteed that all the wedge blocks of the line rail with the same specification are 100% the same in the size. Thanks to the powder metallurgy material, the wedge block is not easily deformed and cracked. When the platform of tool machine is vibrated and affected by the impact force, the slide rail is likely to deviate from the original position, which will affect the original precision. To avoid such case, it is recommended to use the method shown in the above photo to fix the slide rail so that the operation precision can be ensured for the tool machine.
