1. Roller bearings inc shares assembly of the outer ring, two rows of needle rollers and the first eccentric sleeve

The height of the high block is 47mm, and the height of the short block is 28.3mm. The outer ring of the eccentric bearing is supported by the high block and the short block respectively, and the short block does not touch the outer ring. The height of the first eccentric sleeve is the sum of the height of the high block and the height of the rib of the outer ring. Because the first row of needle rollers only touches the rib of the outer ring for 2mm, and the diameter of the needle rollers is 4.5mm, it is difficult to install the needle rollers. The sleeve is used to install the needle rollers. The thickness of the sleeve is 7mm. A through groove is milled on the sleeve, and the size of the opening of the groove is 5.5 mm, which is larger than the diameter of the needle roller. Install the needle roller through the opening, which solves the problem that the needle roller cannot stand upright. This solves the difficult problem of installing the first row of needle rollers. Get rid of the high block and change it to a low block to support the outer ring, and use the sleeve slot to install the second row of needle rollers, thus completing the assembly process of the outer ring, two rows of needle rollers and the first eccentric sleeve.

2. Roller bearings inc shares assembly of outer ring, two rows of needle rollers, first eccentric sleeve, second eccentric sleeve and two rows of needle rollers, assembly of outer ring, two rows of needle rollers, first eccentric sleeve, second eccentric sleeve and The assembly process of the two rows of needle rollers is the same as the above assembly process.

3. Roller bearings inc shares assembly of inner ring and two rows of rollers

The first row of rollers is installed by using the auxiliary equipment for installing rollers. The design principle of the auxiliary equipment is: 4mm is the height of the rib of the inner ring, so that the height of the auxiliary equipment is consistent with the height of the rib of the inner ring before the first row of rollers can be installed. The auxiliary tool is milled with 27 equally divided grooves. The height of the groove is based on blocking the rollers and not falling down. The height of the blocking roller given by this auxiliary tool is 7.6mm, and the groove width should be greater than the roller diameter. Use the auxiliary tool to install people. The first row of rollers is then loaded into the first row of cages, thus completing the loading process of the first row of rollers. The second row of cages is placed on the first row of cages and loaded into the second row of rollers, thus completing the entire assembly process of the inner ring and the two rows of rollers.roller bearings inc

4. Assembling the inner ring, two-row roller assembly and outer ring, first eccentric sleeve, second eccentric sleeve and four-row needle roller assembly Inner ring, two-row roller assembly into the first eccentric sleeve, Among the second eccentric sleeve and the four-row needle roller assembly, the entire assembly process of the entire eccentric bearing is completed in this way.

Due to the complex structure of the eccentric bearing, the assembly process is relatively cumbersome, which brings certain difficulties to the design of assembly aids. Through the application of the above sets of auxiliary tools in the assembly of eccentric bearings, the difficulties in the assembly process of eccentric bearings are solved. The various performances and technical indicators of the assembled eccentric bearings all meet the product requirements.
