Actuating cam type lubricating self-cleaning mechanism

Abstract

The invention relates to an actuating cam type lubricating self-cleaning mechanism. A motor is connected to a large arm in a static sealing mode, an output end of the motor is connected with one end of an output shaft of a speed reducer through an input gear shaft of the speed reducer, one end of a shell of the speed reducer is arranged in the large arm in a static sealing mode, the other end of the shell of the speed reducer is connected with the output shaft of the speed reducer in a sealing rotation mode, and the other end of the output shaft of the speed reducer is connected with a small arm in a in static sealing mode; the two ends of an inertia double-head piston are connected with a large cylinder barrel and a small cylinder barrel in a sealing mode to form sliding pairs correspondingly; and a speed reducer inner cavity filled with lubricating grease is arranged in the large 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 communicates with the speed reducer inner cavity through an oil way B, an oil outlet one-way valve allowing oil to flow to the small cylinder barrel only is arranged in the oil way A, an oil return one-way valve allowing oil to flow to the speed reducer inner cavity only is arranged in the oil way B, and a filter element is arranged in the part, close to the large cylinder barrel, of the oil way B. According to the mechanism, the internal pressure of a robot joint can be stabilized, oil leakage is prevented, the energy efficiency is improved, 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 an active cam 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 perm...
