A chain-type start buffer mechanism

Abstract

The invention relates to the technical field of chain transmission, in particular to a chain-type start-up buffer mechanism, which includes a driven sprocket, a driving sprocket, a motor for driving the driving sprocket to rotate, and a chain wound between the driving sprocket and the driven sprocket ; Also includes a buffer, the buffer is located between the driven sprocket and the driving sprocket; the buffer includes: a shell, the upper and lower sides of the inner wall are symmetrically provided with guide grooves; the guide block, the upper and lower ends of the Slidingly connected in the guide groove; the first transition sprocket and the gear are respectively rotatably connected to the left and right sides of the front end of the guide block; the second transition sprocket is coaxially and fixedly installed on the front end of the gear; the rack is located on the The inner bottom of the casing is meshed with the gear; one end of the spring is set on the left side wall of the guide block, and the other end is fixed on the casing, which is used to push the guide block to reset; the above-mentioned first transition sprocket and the second transition sprocket The sprockets mesh with the chains on both sides respectively.

Description

Technical field [0001] The present invention relates to the field of chain drive technology, specifically to a chain starting buffer mechanism. Background [0002] Chain transmission is a transmission method that transmits the movement and power of the active sprocket with a special tooth shape to the driven sprocket with a special tooth shape through the chain. [0003] Chain transmission has many advantages, compared with the belt drive, no elastic sliding and slipping phenomenon, the average transmission ratio is accurate, the work is reliable, the efficiency is high; the transmission power is large, the overload capacity is strong, the transmission size under the same working conditions is small; the required tension is small, the pressure acting on the shaft is small; it can work in harsh environments such as high temperature, humidity, dustiness and pollution. [0004] Due to the transmission of the chain, the speed of the active sprocket and the driven sprocket is consiste...

AI Technical Summary

Problems solved by technology

[0004] Due to the transmission of the chain, the speed of the driving sprocket and the driven sprocket are consistent; the driving moment of the driving sprocket is large at the moment of starting, and the load of the motor is also large, which is easy to accelerate the aging of the motor, and even cause the motor to be overloaded and damaged.
