Speed reducer structure

Abstract

The invention provides a speed reducer structure, which comprises a box body and a box cover arranged on the top of the box body, wherein a lower support plate is installed in the lower part of the box body; the upper part in the box body is provided with a transparent cover; the transparent cover is provided with a blank cover; the lower support plate is provided with a plurality of lower support plate sliding bearings; a cone roller bearing is installed between the transparent cover and the blank cover; a coupler is installed on the cone roller bearing; a gear speed reduction motor is connected to one end of the coupler; the other end of the coupler is connected with a worm; one ends of worm wheel shafts are installed on lower support plate sliding bearings on the lower support plate; the other ends of the worm wheel shafts are connected to the worm; the end parts of a lengthened worm wheel shaft and the worm wheel shafts are provided with worm wheels. According to the speed reducer structure disclosed by the invention, the worm wheels and the worm are meshed by insection, the worm is effectively driven by the speed reducer, so that the turnover number of the speed reducer is effectively lowered to the required turnover number so as to guarantee power transmission accuracy and high efficiency, the energy waste is reduced, and the energy use ratio is improved.

Description

technical field [0001] The invention relates to a reducer, in particular to a reducer structure with fast and accurate worm gear switching. Background technique [0002] The worm gear reducer is a power transmission mechanism that uses the speed converter of the gear to reduce the number of revolutions of the motor (motor) to the desired number of revolutions and obtain a larger torque. 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. The basic structure of the worm gear reducer is m...
