A joint reducer

Abstract

The invention discloses a novel joint speed reducer, and relates to the technical field of robots. The lower part of a center sun gear is engaged with an input gear; the center sun gear is sleeved in a support planet rack; a straight gear is arranged on the outer side of the support planet rack; the external of the support planet rack is connected with a third pin wheel housing through a main shaft bearing; the internal of the outer end of the third pin wheel housing is connected with an output planet rack through the main shaft bearing; a second pin wheel housing and a first pin wheel housing are arranged between the output planet rack and the support planet rack; an eccentric shaft is inserted in the output planet rack, the second pin wheel housing, the first pin wheel housing and the support planet rack; multiple oil storage holes are formed in the outer wall of the third pin wheel housing; top rubber plugs and bottom rubber plugs are arranged in the oil storage holes; and machine oil is in space between the top rubber plugs and the bottom rubber plugs. The novel joint speed reducer can be termly and quantitatively filled with the machine oil for lubricating maintenance without needing special oiling tools, so that the waste of the oil can be prevented, and the practicability is higher.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a joint reducer. Background technique [0002] A robot is a common name for an automatic control machine (Robot), which includes all machines that simulate human behavior or thoughts and simulate other creatures (such as robot dogs, robot cats, etc.). There are still many classifications and controversies about the definition of robots in a narrow sense, and some computer programs are even called robots. In contemporary industry, a robot refers to a man-made machine device that can perform tasks automatically to replace or assist humans in their work. The ideal high-simulation robot is the product of advanced integrated cybernetics, mechatronics, computer and artificial intelligence, materials science and bionics, and the scientific community is currently researching and developing in this direction. [0003] Robots are generally composed of actuators, driving devices, detection...

Problems solved by technology

After the joint reducer has been used for a period of time, it needs to add lubricating oil to lubricate and maintain its internal structure to ensure that it can work normally. At present, this process is to open a refueling hole on the casing. When maintenance is required, refueling Oil is added to the hole for maintenance. This method requires additional oil, and at the same time needs to use a special tool to inject the oil into the oil filling hole, and the amount of oil can not be accurately grasped, resulting in waste of oil, which needs to be improved urgently
