Self-lubricating speed reducer

Abstract

The invention relates to a speed reduction transmission device. The self-lubricating speed reducer has the advantages of being firm, durable, stable in operation and good in lubricating effect. According to the technical scheme, the self-lubricating speed reducer comprises a machine shell, an input shaft, an output shaft and a transmission mechanism, wherein the input shaft and the output shaft are rotatably positioned on the machine shell, and the transmission mechanism transmits power between the input shaft and the output shaft. The oil pump is characterized in that an oil pumping mechanism driven by the driving shaft and an oil distributing mechanism for distributing lubricating oil supplied by the oil pumping mechanism to all lubricating points are further arranged in the machine shell; the oil pumping mechanism comprises a pressing plate fixed to the end cover, an oil supply cavity located between the end cover and the pressing plate, and an impeller arranged in the oil supply cavity and driven by the driving shaft. An oil inlet and an oil outlet are formed in the bottom and the top of the pressing plate respectively, and lubricating oil can be driven by the impeller to move from the oil inlet to the oil outlet in the circumferential direction of the oil supply cavity.

Description

technical field [0001] The invention relates to a speed reduction transmission device, in particular to a speed reducer. Background technique [0002] Most of the existing reducers adopt the external oil supply mode. The motor drives the oil pump to extract the lubricating oil from the reducer, and then transports it to each lubrication point in the reducer through oil pipes, oil separators, and copper pipes. Circulating supply of lubricating oil to other parts. There are many defects in this external oil supply method: [0003] Oil pumps and oil pipes are arranged outside the reducer, so the structure of the reducer housing is complex, the pipelines are densely covered, maintenance is inconvenient, and the product is not beautiful; during the transportation and use of the reducer, it is very easy to damage the motor or oil pipe due to bumps. Cause the reducer to fail to work normally; the working environment of the reducer is very harsh, maintenance is difficult, and the ...

Problems solved by technology

[0003] Oil pumps and oil pipes are arranged outside the reducer, so the structure of the reducer housing is complex, the pipelines are densely covered, maintenance is inconvenient, and the product is not beautiful; during the transportation and use of the reducer, it is very easy to damage the motor or oil pipe due to bumps. Cause the reducer to fail to work normally; the working environment of the reducer is very harsh, maintenance is difficult, and the motor is limited by the working life. Once the motor fails, the staff will not be able to detect it. If it cannot be dealt with in time, it will cause the bearing to burn and the gear to be damaged; Since the speed of the motor driving the oil pump is fixed, the amount of lubricating oil supplied cannot be adjusted. When the reducer is running at a low speed, the amount of oil supplied by the oil pump is obviously too large, causing the position of the oil seal of the reducer to be flooded with lubricating oil. After a long time of operation Prone to lubricant leakage
