Problems solved by technology

However, the existing chain in the continuously variable transmission bears the axial pressure of the cone while carrying the tension. In addition, in order to improve the polygonal effect of the chain, the diameter of the chain pin should not be too large
When the chain width is increased in order to carry a large torque, if the chain pin shaft is not thickened, it will be bent and deformed when entering the wrap angle area due to insufficient rigidity, thus affecting the transmission performance

Abstract

The invention discloses a chain for improving transmission performance. The chain comprises transmission chain pieces, chain pin shafts and supporting pin shafts, wherein chain pin shaft holes and a supporting pin shaft hole are formed in each transmission chain piece; chain pin shaft holes are symmetrically arranged at two ends of one side of the corresponding transmission chain piece; the supporting pin shaft hole is located on the other side of the corresponding transmission chain piece; the chain pin shafts penetrate through the chain pin shaft holes and the supporting pin shafts penetrate through the supporting pin shaft holes, so that the transmission chain pieces form a transmission chain array. According to the chain for improving transmission performance, the structural design is reasonable, the process can be simplified, meanwhile, the bending strength of the chain joints is increased, so that the chain bears larger torque, and therefore the purpose of improving the transmission performance of the chain is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, and more specifically relates to a chain with improved transmission performance. Background technique [0002] Chains are used extensively in mechanical transmissions, such as in continuously variable transmissions. However, the existing chain in the continuously variable transmission bears the axial pressure of the conical disk while carrying the pulling force. In addition, in order to improve the polygonal effect of the chain, the diameter of the chain pin shaft cannot be too large. When the width of the chain is increased in order to carry a large torque, if the chain pin shaft is not thickened, it will be bent and deformed when entering the wrap angle area due to insufficient rigidity, thus affecting the transmission performance. [0003] Therefore, how to provide a chain capable of improving transmission performance is an urgent problem to be solved by those skilled in the a...
