Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0024] The technical scheme of concrete implementation of the present invention is:

[0025] Such as figure 1 As shown, a non-lubricating step chain, including the inner chain link and the outer chain link;

[0026] The outer chain link includes a pair of outer chain plates 2 connected with the pin shaft 1;

[0027] The inner chain link includes a pair of inner chain plates 3 connected with the sleeve 4;

[0028] The sleeve 4 is sheathed on the outer periphery of the pin shaft 1 and is located between the pair of outer link plates 2;

[0029] The outer circumference of the sleeve 4 is also sleeved with a roller 5, and the roller 5 is located between the...

Abstract

The invention discloses a lubrication-free step chain which comprises an inner chain link and an outer chain link, and further comprises a sleeve-use oiling-free bushing, a pair of seal rings, a pair of flat washers and a pair of annular sealing gaskets, wherein the sleeve-use oiling-free bushing is arranged on the periphery of a pin shaft in a sleeving manner; the pair of the seal rings is arranged on the periphery of the pin shaft in a sleeving manner, and is positioned between a pair of outer chain plates; the sleeve-use oiling-free bushing is positioned between the pair of the seal rings; the pair of the flat washers is arranged on the periphery of a sleeve in a sleeving manner; a pair of inner chain plates is positioned between the pair of the flat washers; the pair of the annular sealing gaskets is arranged on the periphery of the sleeve in a sleeving manner, and is positioned between the pair of the outer chain plates; and the pair of the flat washers is positioned between the pair of the annular sealing gaskets. According to the lubrication-free step chain, grease can be placed in the sleeve-use oiling-free bushing in advance, so that the self lubrication is achieved, the flat washers and the annular sealing gaskets can prevent external pollutants from entering the sleeve, and the pre-placed grease is prevented from being polluted.

Description

technical field [0001] The present invention relates to a lubrication-free step chain. Background technique [0002] The lubrication of the chain transmission is very important. Reasonable and moderate lubrication can greatly reduce the wear of the chain hinge and prolong the service life. Sufficient lubricating grease can also enhance the cooling effect, slow down the meshing impact, and reduce the transmission noise. [0003] At present, the commonly used cascade chains generally adopt traditional lubrication methods such as manual periodic lubrication, drip lubrication, oil bath, splash lubrication, and oil pump injection lubrication. Traditional lubrication methods have a relatively large loss of lubricating oil and are more likely to pollute the environment. Contents of the invention [0004] The purpose of the present invention is to provide a lubrication-free cascade chain, which has a reasonable structure, and grease can be preset in the oil-free bushing for the s...
