Description

Long-life V-shaped bearing chain with two sides

Technical Field

The utility model relates to the technical field of chains, in particular to a long-life bilateral V-shaped bearing chain.

Background

In the traditional chain, the chain adopts a closed structure, and small parts cannot directly fall when falling in the transmission process, so that the chain is clamped, the transmission of the chain is hindered, and even the chain is damaged; the bearings adopted by the traditional chain are old bearings, and the transmission speed of the chain is extremely slow.

Publication No.: CN207049256U, published 2018-02-27, proposes a three-bearing chain, which comprises a plurality of chain shafts, a plurality of chain sheet units, a plurality of bush bearings, a plurality of roller bearings, and a plurality of plane bearings. Each chain piece unit comprises two inner chain pieces and two outer chain pieces, and each inner chain piece is matched with the adjacent outer chain piece to define two overlapping gaps. The bush bearings are respectively sleeved on the periphery of the chain shaft. The roller bearings are respectively sleeved on the peripheries of the bush bearings. The plane bearings are respectively arranged between the overlapping gaps. The three-bearing chain can reduce the collision noise and abrasion generated by sliding by utilizing the clearance between the chain sheet and the chain shaft in the prior chain and can improve the smooth feeling in use by utilizing the rolling mode of the rolling pieces in the bush bearing, the roller bearing and the plane bearing.

In this patent, rolling friction is used instead of sliding friction in the bearing chain to reduce friction between parts and reduce wear during chain operation, but the reduction in friction is only for the parts and not for the entire chain transport, so the chain operation speed is still slow.
