Description

Technical Field

[0001] The utility model relates to the technical field of cam dividers, in particular to a cam intermittent divider structure. Background Art

[0002] The cam divider, also known as the cam indexer or intermittent divider in engineering, is a high-precision rotary device that is widely used in various automation equipment and production lines. Its working principle is mainly based on the profile design of the cam and the coordinated use of needle bearings.

[0003] When the cam contacts the needle bearing on the output turret, it pushes the needle bearing to move along a predetermined trajectory. By precisely controlling the profile and rotation speed of the cam, intermittent rotation of the indexing plate within a specific angle range can be achieved. When the cam divider is working, the cam is constantly in contact and friction with the needle bearing, which not only easily generates heat, but also easily causes wear of the cam, affecting the indexing accuracy and output force. The general treatment method is to deliver lubricating oil directly to the cam surface through an oil spray nozzle for lubrication, but this method cannot control the amount of oil well and is prone to cause internal contamination of the divider.
