Abstract
A track roller has a stepped diameter shaft with a pair of spaced shoulders and an outer track engaging rim with a pair of opposite end faces individually substantially alignable with the shoulders of the shaft. A rim clamping and positioning device is disposable in opposing sliding relation against the shoulders of the shaft for rotatably mounting the rim on the shaft and has a sleeve portion extending in full load bearing relation between the shoulders of the shaft. A pair of opposing clamping surfaces are each positionable in facing, tightly clamping relation against respective ones of the end faces of the rim for limiting relative axial movement between the rim and shaft.
Claims12
A track roller comprising:
- a stepped diameter shaft having a pair of spaced shoulders;
- an outer track engaging rim rotatably mounted on said shaft and having a pair of opposite end faces individually substantially alignable with said shoulders on the shaft;
- and
- rim clamping and positioning means disposable in opposing sliding relation against said shoulders of the shaft and having a sleeve portion extending in full load bearing relation between said shoulders and a pair of opposing clamping surfaces each positionable in facing, tightly clamping relation against respective ones of said pair of end faces of the rim for limiting relative axial movement between said rim and the shaft.
A track roller comprising:
- a stepped diameter shaft defining an elongated, enlarged diameter center portion and a pair of spaced shoulders disposed at the opposite ends of said center portion;
- an outer generally cylindrical track engaging rim having a pair of opposite end faces individually substantially alignable with said shoulders on the shaft;
- and
- rim clamping and positioning means for rotatably retaining said rim on said shaft and including;
- a sleeve portion having a length substantially equal to and in full radial supporting relation along the center portion of the shaft between said shoulders thereof;
- and
- flange means provding a pair of opposing thrust surfaces and a like pair of opposing clamping surfaces with the thrust surfaces being positionable in opposing sliding relation against respective ones of said shoulders of the shaft and the clamping surfaces being positionable in facing, tightly clamping relation against respective ones of said end faces of the rim so as to limit axial movement of the rim relative to the shaft and to mount said rim and shaft in unitary assembly.
