Description

Technical Field

[0001] The utility model relates to the technical field of worm gear reducers, in particular to a worm gear reducer with a seismic-resistant component. Background Art

[0002] A worm gear reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of a motor to the desired number of revolutions and obtain a larger torque. In mechanisms used to transmit power and motion, reducers have a wide range of applications. The main function of a reducer is to reduce speed while increasing output torque. The torque output ratio is calculated by multiplying the motor output by the reduction ratio. The reduction in inertia of the load is reduced by the square of the reduction ratio. During the use of existing worm gear reducers, due to their poor seismic performance, long-term operation of the worm gear will cause the reducer to vibrate, which is prone to generate loud noise, affecting the noise reduction effect of the worm gear reducer when in use. Therefore, we propose a worm gear reducer with a seismic-resistant component to solve the above problems. Utility Model Content

[0006] Preferably, the worm gear assembly includes a worm and a transmission worm wheel which are rotatably connected to the reducer body from top to bottom, and the worm is meshingly connected to the bottom of the transmission worm wheel.

[0007] Preferably, a motor mounting seat is fixedly connected to the side of the reducer body, and a plurality of mounting grooves are spaced apart on the side of the motor mounting seat.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model provides an anti-seismic component, an upper buffer block and a lower buffer block. If the reduction machine body vibrates, the guide rod and the assembly disk are driven to rise and fall, the longitudinal spring is deformed to generate resistance, and the lower buffer block and the upper buffer block can play a blocking and buffering role for the vibrating reduction machine body. The transmission rod is movably hinged between the assembly disk and the transmission sleeve. The transmission rod can drive the transmission sleeve to slide, so that the transverse spring is deformed to generate resistance, which can produce multiple damping and shock-absorbing effects on the reduction machine body, improve the anti-seismic performance of the worm gear reducer, prevent the worm gear reducer from easily generating large noise during operation, and is conducive to improving the noise reduction effect during use.
