Abstract
A cam follower roller assembly has a shaft insertable into a roller. The shaft has a zerk in communication with the channel wherein lubricant can be added to the assembly. The design of the assembly in one embodiment is such that a larger shoulder to shaft radius stabilizes the shaft and limits the shaft from rocking or elongating within a mounting hole. When utilized in the application of a loading mechanism and carriage assembly for trash collection vehicles, one embodiment of the cam follower roller assembly provides greater life and easier serviceability.
Claims11
A cam follower roller assembly for a trash collection vehicle carriage, comprising:
- a shaft;
- a roller;
- the shaft insertable into the roller;
- the shaft has a first end and a second end;
- a zerk;
- the shaft having a channel;
- the shaft having at least one secondary channel;
- wherein a lubricant can flow through the zerk, the channel and the at least one secondary channel to lubricate a portion of the cam follower roller assembly;
- the shaft has a shoulder;
- the shoulder between the first end and the second end of the shaft;
- the roller having an inner edge;
- the shoulder having a bottom;
- the bottom of the shoulder making continuous contact with the inner edge for an entirety of a circumference of the bottom of the shoulder;
- wherein the bottom of the shoulder is
- a bearing surface;
- the shaft and the shoulder
- are rotatable within the roller;
- the shoulder having a diameter greater than any diameter of the shaft;
- wherein the diameter of the shoulder mitigates rocking of the shaft within the roller.
A cam follower roller assembly for a trash collection vehicle carriage, comprising:
- a shaft;
- a roller;
- the shaft insertable into the roller;
- a zerk;
