Embodiment Construction

[0012] The present invention is described below in conjunction with accompanying drawing.

[0013] as attached figure 1 The sleeve of the present invention includes a sleeve body 1, a circular through hole 2 is opened at the middle position of the sleeve body 1; Several oil storage grooves 3 are evenly arranged at the positions; the length of the oil storage grooves 3 is less than the height of the sleeve body 1 .

[0014] as attached figure 2 The sleeve of the present invention acts on the chain together with the pin shaft 4, and lubricating oil is added to the sleeve. The lubricating oil can be stored for a long time in the oil storage tank 2 provided on the inner wall of the sleeve. The wear-resistant damage of the chain itself is reduced, thereby prolonging the service life of the chain.

[0015] The above-mentioned embodiments are only to illustrate the technical conception and characteristics of the present invention. Substantial equivalent changes or modifications ...

Abstract

The invention discloses a bushing, which comprises a bushing body, wherein the middle position of the bushing body is provided with a circular through hole; and a plurality of oil storage grooves are uniformly arranged on the middle position of the inner side wall of the bushing body in the length direction, and the length of each oil storage groove is smaller than the height of the bushing body. The bushing and a pin shaft collectively act on a chain, lubricating oil is applied onto the bushing, the lubricating oil can be stored inside the oil storage groove which is arranged on the inner side wall of the bushing for a long time, the wear-resisting harm on the chain can be reduced, and the service life of the chain can be prolonged.

Description

technical field [0001] The invention relates to a sleeve, in particular to a sleeve used on a chain to prolong the service life of the chain. Background technique [0002] The currently used sleeve acts on the chain together with the bearing pin during use, and the chain is more severely worn during use, and its service life is not long. Contents of the invention [0003] In view of the above-mentioned technical problems, the purpose of the present invention is to propose a sleeve used on the chain that can prolong the service life of the chain. [0004] The technical solution of the present invention is achieved as follows: a sleeve, including a sleeve body, a circular through hole is opened in the middle of the sleeve body; the inner side wall of the sleeve body is provided with several storage An oil groove, and the length of the oil storage groove is less than the height of the sleeve body. [0005] Preferably, the oil storage tank is evenly arranged at a middle posi...
