Description
Technical Field
The utility model relates to a transmission structure, especially a light transmission structure of bicycle buncher.
Background
Bicycle buncher, realize the purpose of speed governing through adjusting the steel ball angle, bicycle buncher has the variable speed steadily, it is smooth, the advantage of no pause or pause, but present bicycle buncher adopts mostly as the used structure of figure 4, for convenience of assembly and cost-effective steel ball subassembly end is the square head, and be plastic construction, cause and need great power when carrying out the speed governing, cause and ride and experience not good, consequently need develop new structure in order to satisfy the portability of bicycle buncher speed governing.
Disclosure of Invention
The purpose of the invention is as follows: aiming at the problems, the defects are overcome, and the lightweight transmission structure of the bicycle continuously variable transmission is provided, and the lightweight speed regulation is realized by redesigning the structure of the steel ball component and the structure of the speed regulation disc.
The technical scheme is as follows: comprises a main shaft, a fixed seat, a steel ball component, an idler wheel, a movable disc and a speed regulation disc; the steel ball assembly comprises an end cap, a pin shaft and a steel ball, the steel ball can rotate along the pin shaft, and the end cap is cylindrical and provided with a circular groove; the speed regulation disc is provided with an arc groove, the arc groove of the end cap is matched with the arc groove on the speed regulation disc, and the steel ball assembly can slide along the arc groove on the speed regulation disc; the steel ball component is arranged in a cavity formed by the fixed seat and the movable disc; the idler is mounted on the main shaft with the surface of the idler in contact with the surface of the steel ball.
Furthermore, the end cap is made of a metal material.
Further, the idler is a deep groove ball bearing with an arc groove on the surface.
Further: the steel ball components are arranged in 6 pairs.
Furthermore, the steel ball of the steel ball component is made of alloy materials.
Furthermore, lubricating grease is coated between the circular groove of the end cap and the matching surface of the circular groove on the speed regulation disc.
The utility model discloses the principle: the end cap of the steel ball component is changed into a round shape from a square shape, and the end cap is provided with an arc groove which is matched with the arc groove on the speed regulation disc, so that the transmission resistance is reduced.
Has the advantages that: compared with the prior art, the invention has the advantages that: change into circularly by square through the steel ball subassembly end cap, and it has the circular arc groove to open on the end cap, cooperatees with the circular arc groove on the speed governing dish, realizes driven resistance and reduces, and the speed governing resistance of solving current bicycle continuously variable transmission is big, rides and experiences not good problem.
