An Active Cam Type Lubricating Self-cleaning Mechanism

Abstract

The invention relates to an active cam 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 on the large arm with static seal. In the arm, 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 forearm in a static seal; the two ends of the inertial double-headed piston form a moving pair with the large and small cylinders respectively and are connected in a sealed manner. There is a reducer inner cavity filled with grease. The reducer inner cavity is connected to the inside of the small cylinder through the oil passage A, and the inside of the large cylinder is connected to the reducer inner cavity through the oil passage B. In the oil passage A There is an oil outlet check valve that can only flow to the small cylinder, and an oil return check valve that can only flow to the inner cavity of the reducer in the oil passage B; a filter element is installed in the oil passage 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 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...
