Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] like figure 1 , figure 2 As shown, the present invention includes a boom 1, a small arm 7, a motor 2 and a reducer housing 3 respectively accommodated in the boom 1, a reducer input gear shaft 4, a reducer output shaft 5, an elastic mechanism 10, an oil outlet One-way valve 11, oil return one-way valve 12 and filter element 13, in which the motor 2 is statically sealed and fixedly connected to the boom 1, the output end penetrates into the boom 1, through the input gear shaft 4 of the reducer and the output shaft 5 of the reducer One end of the reducer casing 3 is statically sealed and fixedly connected to the boom 1, and the other end is connected to the output shaft 5 of the reducer through a rotating dynamic seal 6. The other end of the reducer casing 3 is connected to the input shaft of the reducer. The gear shaft 4, the output shaft 5 of the re...

Abstract

The invention relates to an internal circulation 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 inner cavity of the reducer is arranged in the boom, and the inner cavity of the reducer is connected to the elastic mechanism through the oil circuit A. One end is connected, and the other end of the elastic mechanism is connected with the inner cavity of the reducer through the oil passage B. In the oil passage A, there is an oil outlet check valve that can only flow to the elastic mechanism, and in the oil passage B, there is a check valve that can only flow to the The oil return one-way valve in the inner cavity of the reducer; a filter element is provided in the oil circuit B near the other end of the elastic mechanism. The invention can stabilize the internal pressure of the joints of the robot, prevent oil leakage, reduce the rotational resistance of the joints of the robot, reduce energy efficiency, and have better and more remarkable effects of energy saving and environmental protection.

Description

technical field [0001] The invention relates to a cleaning lubricating system for robot joints in the cleaning industry, in particular to an internal circulation lubricating 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 relat...
