Passive pendulum bob type lubricating self-cleaning mechanism

Abstract

The invention relates to a passive pendulum bob type lubricating self-cleaning mechanism. The passive pendulum bob type lubricating self-cleaning mechanism is characterized in that a motor is fixedlyconnected to a big arm in a static sealing manner, the output end of the mechanism is connected with one end of a speed reducer output shaft through a speed reducer input gear shaft, one end of a speed reducer shell is arranged in the big arm in a static sealing mode, the other end of the speed reducer shell is in sealing rotation connection with the speed reducer output shaft, the other end of the speed reducer output shaft is in static sealing connection with a small arm, the two ends of a double-head piston rod are correspondingly connected with a large cylinder barrel and a small cylinderbarrel to form a movable pair and are in sealed connection, a pendulum bob is hinged to the big arm and is connected with the double-head piston rod through a connecting rod, a speed reducer inner cavity is arranged in the big arm, the speed reducer inner cavity communicates with the interior of the small cylinder barrel through an oil way A, the interior of the large cylinder barrel communicateswith the speed reducer inner cavity through an oil way B, an oil outlet one-way valve is arranged in the oil way A, an oil return one-way valve is arranged in the oil way B, and a filter element is arranged in the oil way B close to the large cylinder barrel. According to the passive pendulum bob type lubricating self-cleaning mechanism, the internal pressure of a joint of a robot can be stabilized, oil leakage is prevented, the energy efficiency is reduced, and the energy-saving and environment-friendly effects are better.

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...
