Eccentric cam follower is a very important bearing

Eccentric cam follower bearing is a very important bearing in cycloidal pinwheel reducer. The eccentric cam follower bearing consists of three parts: an eccentric sleeve and two 502 series cylindrical rollers. The eccentric sleeve and the inner ring of the eccentric cam follower bearing are integrated into one, forming an eccentric bearing.
Characteristics of eccentric cam follower bearings: The inner hole of the inner ring is an eccentric hole, and there is a longitudinal keyway on the inner wall of the eccentric hole.

Applications of eccentric cam follower bearings: gearboxes, petrochemicals, textiles, metallurgy, mining, etc
The eccentric cam follower bearing adopts the following processes and fixtures.
Firstly, process all the outer circles of benchmark A and leave 50mm long 25mm process clamps at both ends of the shaft. The clamps should be coaxial with benchmark A and the step surface should be perpendicular to benchmark A.
Tooling production: Two card cans, requiring slot 42H7 to be symmetrical with center hole B5, and the end face of the slot to be perpendicular to the center hole. Place the card can at both ends of the shaft, and the eccentric direction of the card can should be consistent.

The eccentric direction is controlled by the fit between the slot of the card can and the flat 42H7/h6 of the shaft; The eccentricity can be adjusted by adjusting the compression screw on the canister; Press the end face of the can tightly against the stepped surface of the shaft, ensuring that the center of the shaft is parallel to the center of the can.
Use double pointed clamps on the lathe, clamp the can with four claws and rotate it. Measure the outer circles of both ends with a gauge based on the A reference, adjust the screws on the can to different eccentricities.
