Worm gear speed reducer and oil filtering method thereof

Abstract

The invention relates to a worm gear speed reducer. The worm gear speed reducer comprises a machine body, a worm gear fixedly installed in the machine body and a worm penetrating through the machine body to be matched with the worm gear, wherein an oil inlet is formed in the upper end of the machine body, an oil outlet is formed in the outer side of the machine body, a pressure lubricating device is further fixedly installed on the machine body, and a fixing base used for rotating and sealing the worm is further arranged in the machine body. The pressure lubricating device comprises a first filtering device arranged at the oil inlet, a second filtering device arranged at the oil outlet, an oil storage tank, a pressure pump arranged at the upper end of the machine body and communicated with the first filtering device, and an oil suction pump used for communicating the second filtering device with the oil storage tank. The worm gear speed reducer has the beneficial effects that self-cleaning of filter elements of the filter devices is achieved, the filtering part, located at the opening, of the filter element can be switched, the service life of the filter element is prolonged, cost is reduced, and meanwhile the use efficiency of the speed reducer is improved.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a worm gear reducer and an oil filtering method thereof. Background technique [0002] Worm gear reducer is a power transmission mechanism of worm gear reducer. It uses the speed converter of the gear to reduce the mutual speed of the motor to the desired number of revolutions and obtain a larger torque mechanism. It is currently used for power transmission and motion. In the mechanism, the application range of the reducer is quite wide. [0003] With the development of the times and technology, technological progress has also promoted the technological progress of the worm gear reducer. In the existing technology, the worm gear reducer motor needs to be lubricated frequently, but impurities are often mixed in the lubricating oil, and a filter device is required. Filter the lubricating oil to prevent impurities from remaining in the motor, but the existing filter device needs t...

Problems solved by technology

[0003] With the development of the times and science and technology, the progress of science and technology also promotes the technological progress of the worm gear reducer. In the existing technology, the worm gear reducer motor needs to be lubricated frequently, but impurities are often mixed in the lubricating oil, and a filter device is required. Filter the lubricating oil to prevent impurities from remaining in the motor, but the existing filter device needs to take out the filter element frequently to clean or replace it to prevent clogging, but manual operation is extremely cumbersome and affects work efficiency
