Description
Technical Field
The invention relates to the technical field of driving reducers, in particular to a maintenance method for the deformation of a driving reducer shell for a shield machine.
Background
The presence of the drive retarder has two roles, the first is to change the direction of power transmission and the second is to provide a common gear ratio for each gear as an extension of the variator. The output of the transmission is a torque that rotates about a longitudinal axis, while the wheels must rotate about a transverse axis of the vehicle, which requires a device to change the direction of power transmission. The drive reducer is so called because the ratio of the device is a factor of the overall ratio, regardless of the gear position of the transmission. With the transmission ratio, the requirement on the speed reducing capacity of the transmission can be effectively reduced, and the design has the advantages that the size of the transmission can be effectively reduced, so that the overall arrangement of the vehicle is more reasonable.
The automobile driving speed reducer mainly has the functions of speed reduction and torque increase. The output power of the engine is constant, and according to a power calculation formula W-M-v (power-torque-speed), when the transmission speed is reduced by driving the speed reducer, a relatively high output torque can be obtained, so that a large driving force can be obtained. In addition, the automobile driving speed reducer also has the functions of changing the power output direction and realizing the differential speed of the left wheel and the right wheel or the differential speed of a middle rear axle;
however, the right side of the shell of the existing driving reducer is seriously deformed, and an output spindle cannot normally penetrate through the shell to complete assembly, so that the maintenance method for the deformation of the shell of the driving reducer for the shield machine is provided.
