Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, 2, 3 and 4, the self-lubricating tail wheel device of the bucket elevator comprises a support shaft 3 and a tail wheel 2 fixedly installed on the support shaft 3;
the two ends of the supporting shaft 3 are respectively provided with a notch 31 arranged along the axis of the supporting shaft and are respectively rotatably arranged on the bucket elevator 1 through a bearing assembly 4;
each group of bearing assemblies 4 comprises a bearing inner ring 41 and a bearing outer ring 43, the bearing inner ring 41 is provided with a blind hole 42 matched with one end of the support shaft 3, one end of the support shaft 3 is inserted into the blind hole 42 to ensure that the bearing inner ring 41 rotates along with the support shaft 3,
as another scheme, two ends of the support shaft 3 can be arranged in the blind cavity of the bearing inner ring 41 through flat keys;
the bearing outer ring 43 is fixedly and hermetically arranged on the bucket elevator 1, a first blind cavity 44 is arranged on one inward side of the bearing outer ring, and the bearing inner ring 41 is in clearance fit and rotatably arranged in the first blind cavity 44;
further, the diameter of the first blind cavity 44 is 0.1-2mm larger than the outer diameter of the bearing inner ring 41.
As shown in fig. 5, further, a second blind cavity 45 is arranged at the lower end of the first blind cavity 44 along the radial direction thereof, a support plate 47 is arranged in the second blind cavity 45, and the support plate 47 is in elastic contact with the bearing inner ring 41 through an elastic component;
further, the elastic component is a spring 46, the lower end of the spring 46 is in contact with the bottom end of the first blind cavity 44, and the upper end of the spring 46 is connected with a supporting plate 47;
further, the upper end of the supporting plate 47 is arranged to be an arc-shaped structure matched with the inner wall of the first blind cavity 44;
