Abstract

The invention relates to a passive pendulum type lubricating self-cleaning mechanism. The motor is statically sealed and connected to the boom, the output end is connected to one end of the output shaft of the reducer through the input gear shaft of the reducer, and one end of the reducer casing is installed in the static seal In the boom, the other end is connected to the output shaft of the reducer in a sealed rotation, and the other end of the output shaft of the reducer is connected to the small arm in a static seal; the two ends of the double-headed piston rod form a moving pair with the large and small cylinders respectively and are sealed and connected. The hammer is hinged in the boom and is connected with the double-headed piston rod through the connecting rod; there is a reducer inner cavity in the boom, and the reducer inner cavity is connected with the inside of the small cylinder through the oil passage A, and the inside of the large cylinder is passed through the oil Road B is connected with the inner cavity of the reducer, and oil outlet check valve is set in oil line A, and oil return check valve is set in oil line B; a filter element is set in oil line B near the large cylinder. The invention can stabilize the internal pressure of the robot joints, prevent oil leakage, reduce energy efficiency, and have better energy-saving and environmental protection effects.

Description

technical field [0001] The invention relates to a robot joint cleaning lubrication system in the cleaning industry, in particular to a passive pendulum type lubrication self-cleaning mechanism. Background technique [0002] The joints of the robot contain motors and reducers. For routine applications, there may be oil leakage or leakage for many reasons. However, it is absolutely not allowed to be used in the clean industry. If the reducer is in a relatively closed state, a certain amount of friction will be generated between each pair of gears in the reducer, and this friction will emit a certain amount of heat; The extension of time will directly lead to a certain degree of temperature increase in the reducer box; and the volume of the reducer box remains unchanged, so the pressure in the reducer box will also increase accordingly, and the lubricating oil in the box will After splashing, it will be sprinkled on the inner wall of the gear box. Since the oil is relatively...
