Background

At present, in the solid waste recycling industry, a single-shaft shredder in a small solid waste recycling product is always in a transmission structure of a belt and a speed reducer. The transmission structure is repeatedly verified in the industry, has higher reliability, but has the following defects:

as shown in fig. 1, fig. 1 is a schematic diagram of a belt + speed reducer transmission structure in the prior art, in the transmission structure, a motor outputs power to drive a driving pulley (2) on the motor (1) to transmit, the driving pulley (2) transmits energy to a driven pulley (3) through a belt (4), the driven pulley (3) inputs power into a speed reducer (7), and the power is output to a working shaft in a low-speed and high-torque manner through two-stage or multi-stage speed reduction of the speed reducer (7) so as to achieve equipment crushing operation. In the process, energy loss is caused in each transmission link through belt transmission, primary gear speed reduction and secondary gear speed reduction (or multi-stage gear speed reduction), so that the effective power transmitted to the working shaft by the motor is less than 85%, and the residual energy is lost in the form of heat. Secondly, the gear transmission is hard tooth surface bonding transmission, the buffer effect is not achieved, and the impact in the material crushing process cannot be avoided, so that the speed reducer can bear impact load for a long time, the transmission tooth surface of the speed reducer is abraded after long-term work, and the phenomena of reduction of transmission precision, reduction of transmission efficiency, abnormal transmission sound, induction of fatigue fracture of a transmission shaft and the like are easily caused. Gear drive needs oil lubrication, and oil lubrication needs to have seal structure again, because long-term impact action, the lubricating oil that lasts the high temperature needs periodic replacement, and the oil leak phenomenon takes place easily after the sealing element on the speed reducer ages.

In conclusion, the transmission structure of the single-shaft shredder in the prior art has the disadvantages of high use cost, inconvenient installation, careless disassembly and assembly process and easy fracture of the reducer shell.
