Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example (b):

as shown in the figures 1-4 of the drawings,

the utility model provides an abrasionproof decreases selenium drum gear, 1 and gear shaft 2 including integrated into one piece's gear portion, a plurality of groups recess 4 have been seted up on the periphery wall of gear shaft 2, a plurality of groups recess 4 are annular array and distribute on the periphery wall of gear shaft 2, same group recess 4 is linear array and distributes, the diameter of runner 6 is greater than the groove depth 1-2mm of recess 4, the both sides centre of a circle department fixedly connected with of runner 6 is the commentaries on classics ball 7 of hemisphere form, the same and the groove depth of recess 4 both sides is seted up and is less than the radial spout 5 of commentaries on classics ball 7 rather than length direction, 5 terminal intercommunications of spout have the rotation groove that is located recess 4, the rotation groove is used for holding commentaries on classics ball 7 and rotates.

Seted up a plurality of oil storage tanks 3 on the periphery wall of gear shaft 2, oil storage tank 3 is the strip recess 4 of circular arc bottom surface, and its length direction along gear shaft 2 sets up and runs through the both ends of gear shaft 2, and a plurality of oil storage tanks 3 are the annular array and distribute and be the alternate setting with every group recess 4 on the periphery wall of gear shaft 2.

When the gear shaft 2 needs to rotate relative to the inner wall of the circular hole of the end cover, the rotating wheel 6 can be abutted against the inner wall of the circular hole of the end cover, the rotating wheel 6 rotates through the rotating ball 7 in a hemispheroid shape, the rotating wheel 6 rotates, the friction force generated when the gear shaft 2 rotates relative to the inner wall of the circular hole of the end cover is reduced, the abrasion between the gear shaft and the inner wall of the circular hole of the end cover is reduced, the lubricating oil in the oil storage groove 3 can be guided out between the gear shaft 2 and the inner wall of the circular hole of the end cover, the friction force between the gear shaft and the inner wall of the circular hole of the end cover is reduced, the loss is reduced, the service life of the selenium drum gear is prolonged, the use precision of the selenium drum gear can be improved, when a whole selenium drum gear is obtained, people can align the rotating wheel 6 with the groove 4, the hemispheroid, the rotating ball 7 is elastically deformed to enter the sliding groove 5 to slide, and then the rotating wheel 6 just enters the groove 4 after the rotating ball 7 enters the rotating groove, so that the selenium drum gear is assembled.
