Four-shunting speed reducer for crusher

Abstract

The four-flow-dividing speed reducer comprises the crusher and the four-flow-dividing speed reducer body arranged on one side of the crusher, and a supporting bottom plate is installed at the bottom of the crusher; the four-flow-dividing speed reducer is arranged on one side of the upper surface of the supporting bottom plate, a top cover is installed on the top of the four-flow-dividing speed reducer, and fixing screws are installed on the upper surfaces of the front end face and the rear end face of the top cover; the first transmission shaft is arranged in the four-flow-dividing speed reducer, and the first transmission shaft is rotationally connected with the interior of the four-flow-dividing speed reducer. Four gears are meshed in the same plane, the rigidity of a shaft is improved, and therefore the problems that an existing speed reducer for a crusher is generally a coaxial speed reducer, the transverse size of the speed reducer is small, the depths of two pairs of gears immersed in oil are roughly the same, the axial size is large, the weight is large, an intermediate shaft is long, rigidity is poor, and the service life is short are effectively solved. And the load distribution along the tooth width is not uniform.

Description

technical field [0001] The invention relates to the technical field of reducers for crushers, in particular to a four-splitting reducer for crushers. Background technique [0002] The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the prime mover and the working machine. According to the layout of the transmission, it can be divided into expansion reducer, shunt reducer and coaxial reducer. It plays the role of matching speed and transmitting torque between prime mover and working machine or actuator. The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft.

AI Technical Summary

Problems solved by technology

[0003] Existing reducers for crushers are generally coaxial reducers, the reducer has a small lateral dimension, and the two pairs of gears are immersed in oil at approximately the same depth, but the axial dimension is large and the weight is large, and the intermediate shaft is long and poor in rigidity , the problem of uneven load distribution along the tooth width
