Speed reducer for punching machine

Abstract

The invention relates to the technical field of punching equipment, and provides a speed reducer for a punching machine. The speed reducer comprises a power input mechanism, wherein a plurality of driving motors are detachably arranged on the power input mechanism, and the output end of each driving motor is provided with a main gear; a first-stage speed reducing mechanism provided with first driven wheels meshed with the main gears; a second-stage speed reducing mechanism provided with a second driven wheel, wherein the second driven wheel is connected with the first driven wheels through first rotating shafts, and a plurality of third driven wheels are arranged on the outer side of the second driven wheel; and a power output mechanism arranged on the second-stage speed reducing mechanism in a sleeving manner. Compared with the prior art, the speed reducer mainly has the following advantages that the plurality of driving motors can be loaded at the same time, and larger torque can be provided on the premise that parameters of the gears on the speed reducing mechanisms are not changed; and compared with a mode of a first-stage speed reducing mechanism of a traditional speed reduction rack, the speed reducer is simpler in structure and more convenient to install.

Description

technical field [0001] The invention relates to the technical field of stamping equipment, in particular to a speed reducer for a stamping machine. Background technique [0002] The reducer is a power transmission mechanism that does not generate power itself. Its function is to reduce the number of revolutions of the motor (motor) to the desired number of revolutions by using gears of different sizes and speed converters, and obtain a larger speed. moment mechanism. The reason why the reducer is used instead of the motor directly connected to the equipment is because if the motor is directly connected to the equipment, when the equipment is running, the load on the motor is very large, which will cause great damage to the motor, and After the reducer is different, for example, the reducer with a reduction ratio of 100, the speed ratio of the reducer = input speed / output speed, if the speed ratio is 100, the output torque is about 100 of the input torque times. (the speed...

Problems solved by technology

[0004] However, the complex structure of the planetary reducer is not conducive to subsequent installation and maintenance, and there is only one input shaft that can only be connected to one drive motor. When the torque required by the equipment exceeds the rated torque of the existing drive motor, the original drive The motor cannot be used, and in most cases, when the ordinary reducer is used, it needs to be used with an additional one-stage reducer to prevent the reducer from burning out due to excessive initial load, which lengthens the reducer installation and commissioning time
