Heavy-load worm and gear speed reducer

Abstract

The invention relates to the technical field of worm and gear speed reducers, in particular to a heavy-load worm and gear speed reducer which comprises a speed reducer shell, stabilizing feet and a connecting plate; and the stabilizing feet are fixedly connected to the lower end of the speed reducer shell, and the connecting plate is fixedly connected to the upper end of the speed reducer shell. According to the heavy-load worm and gear speed reducer, the defects in the prior art are overcome, by arranging a limiting plate, buffer springs and damping plates, when the speed reducer shell is collided by external force, pressure generated by collision extrudes the buffer springs so that the buffer springs can drive the damping plates to move left and right, and when the damping plates move to the limiting plate, the damping plates drive the buffer springs to rebound; and thus, the buffering protection function can be achieved on worms, worm gears and other components in the speed reducer shell, the situation that pressure generated when the speed reducer shell is collided directly acts on the worm, the worm gear and other components in the speed reducer shell is avoided, the situation that the components are damaged is avoided, and the use safety of the speed reducer is improved.

Description

technical field [0001] The invention relates to a worm gear device, in particular to a heavy-duty worm reducer. Background technique [0002] It can be seen in the transmission system of various machinery, from ships, automobiles, locomotives, heavy machinery used in construction, processing machinery and automatic production equipment used in the machinery industry, to common household appliances in daily life , clocks and more. Its application ranges from the transmission of large power to small loads. The precise angle transmission can be seen in the application of the reducer, and in industrial applications, the reducer has the function of reducing speed and increasing torque. Therefore, it is widely used in the conversion equipment of speed and torque, and the worm gear reducer is a kind of power transmission mechanism, which uses the speed converter of the gear to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger to...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a heavy-duty worm gear reducer, which overcomes the deficiencies of the prior art, has a simple structural design, and effectively solves the problem of the existing heavy-duty worm gear reducer in the actual use process. The heat dissipation effect is not good, so that the heat generated by the components in the reducer housing during the working process is accumulated in the reducer housing, resulting in excessive temperature in the reducer housing, and the components in the reducer housing may be short-circuited. Workers are required to disassemble and overhaul the parts in the reducer housing, which increases the workload of the staff and increases the cost of the use of the reducer, which is not conducive to actual use, and the existing heavy-duty worm gear reducer is not suitable for actual use. There is no shock-absorbing structure in the gear box, and when the reducer housing is hit by a collision, it cannot protect the worm and worm gear inside the reducer housing, causing the pressure generated by the collision to directly act on the worm and worm gear and other components, resulting in The occurrence of component damage reduces the safety of the reducer and is not conducive to the actual use of the problem
