Problems solved by technology

[0002] In the manufacturing process of existing transmission chains, there is basically a welding or riveting process between the chain plate and the pin shaft, which leads to an increase in cost and a decrease in reliability. "chain", the axial restraint of the swing pin on the outer chain piece is welded with thin stop pins at both ends of the swing pin. This process is difficult, and this link is the main factor for the failure of this type of metal chain, and it is the restriction of its life reliability. point

Embodiment Construction

[0013] combine Figure 1 to Figure 6 According to the structural description, we can clearly see the design method of the chain without solder joints and riveting points. The chain is composed of: constraint chain piece, transmission chain piece and pin shaft. It is characterized in that the outer chain piece and pin of the traditional chain are cancelled. The welding or riveting process between the shafts uses special restraint chain pieces and transmission chain pieces to alternately overlap and assemble at intervals on both sides of the chain, so that the outer sides of the entire chain can be integrated into one body and play a role in the axial direction of the outer chain pieces. Constraint.

[0014] For the chain type continuously variable transmission, since the whole chain is assembled by alternately lapping the restraining chain and the transmission chain to connect the two outer chains into one, all the chains in the wrap angle area are clamped by two cone discs for...

Abstract

A constraint chain piece, a chain, a chained stepless speed regulator, and a chain design method. The constraint chain piece (2) is a combined body by integrally connecting two chain pieces with a constraint connection region (4), and implements clamping and constraint for the adjacent chain piece. The constraint chain piece (2) and a transmission chain piece (1) are alternately assembled at a spacing, so that the whole chain are integrally connected at the outer side, thereby constraining the outer-side chain piece; for the manufacturing process, the chain without a welding spot and a riveting spot omits the conventional welding or riveting process, thereby reducing the manufacturing cost, improving the reliability, and prolonging service life.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission design and manufacture. Background technique [0002] In the manufacturing process of existing transmission chains, there is basically a welding or riveting process between the chain plate and the pin shaft, which leads to an increase in cost and a decrease in reliability. "chain", the axial restraint of the swing pin on the outer chain piece is welded with thin stop pins at both ends of the swing pin. This process is difficult, and this link is the main factor for the failure of this type of metal chain, and it is the restriction of its life reliability. point. Contents of the invention [0003] The present invention proposes an improved design scheme for this problem. On both sides of the chain, a newly designed special restraining chain piece and a transmission chain piece are used to alternately overlap and assemble at intervals, so that the outer side of the entire chain ca...
