Detailed Description
The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
Example 1: a chain wheel tensioning device comprises a tensioning base 1, wherein a chain wheel shaft 2 is arranged on the tensioning base 1, one end of the chain wheel shaft 2 is fixedly connected with a chain wheel 3 through a set screw, a chain wheel shaft sleeve 7 is sleeved on the outer side of the other end of the chain wheel shaft 2, and the chain wheel shaft sleeve 7 is arranged on the tensioning base 1 in a sliding mode.
As shown in fig. 1, in order to reduce friction and wear when the sprocket shaft 2 rotates, bearings 8 are respectively fitted to both ends of the sprocket shaft 2, and the inner side of the inner ring of the bearing 8 is in transition fit with the outer side of the sprocket shaft 2 and the outer side of the outer ring of the bearing 8 is in transition fit with the inner side wall of the sprocket bushing 7. When the chain wheel 3 rotates, the chain wheel shaft 2 is driven to rotate, and when the chain wheel shaft 2 rotates, the inner ring of the bearing 8 is driven to rotate simultaneously, so that the friction force and the abrasion of the chain wheel shaft 2 during rotation can be reduced, and the rotation precision of the chain wheel shaft 2 is improved.
As shown in fig. 1, a steel plate 4 is disposed above the sprocket shaft 2, an adjusting screw 6 for driving the sprocket shaft 2 to move up and down is disposed on the steel plate 4, and an axis of the adjusting screw 6 is perpendicular to an axis of the sprocket shaft 2.
