Description

Technical Field

[0001] The utility model relates to the technical field of speed reducers, and more specifically to a lubricating oil delivery structure for speed reducers. Background Art

[0002] A reducer is a device used to reduce speed and increase torque. It is usually installed on the output shaft of an engine or electric motor. It can convert high-speed, low-torque output power into low-speed, high-torque output power, thereby driving the movement of mechanisms that require low speed and high torque.

[0003] After searching, the utility model patent with publication number CN218913689U discloses a lubricating oil delivery structure for a reducer, including a reducer housing, an oil pump, an oil channel and an oil spray ring; the oil channel is arranged on the reducer housing, the oil pump is installed at the lubricating oil inlet, one end of the oil channel is connected to the oil pump outlet, and the other end is connected to the oil spray ring, and also includes an annular cooling plate arranged between the reducer housing and the stator, and the inner wall of the annular cooling plate is provided with a plurality of cooling oil grooves; the cooling oil grooves are connected to the oil channel, and the lubricating oil in the oil channel flows through the outer surface of the stator through the cooling oil grooves and reaches the closed cavity formed between the oil spray ring and the reducer housing; this patent increases the contact area between the lubricating oil and the motor stator by adding a plurality of cooling oil grooves on the basis of the existing oil channel, so as to make the cooling more sufficient and solve the problem that the existing lubricating oil delivery structure has poor cooling effect on the motor stator. However, the above patent still has the following shortcomings: when the lubricating oil lubricates the reducer, the wear and tear debris generated by the transmission components in the reducer will be mixed in the lubricating oil, which is inconvenient to handle the impurities and debris in the lubricating oil. In addition, the lubricating oil in the reducer will be affected by the transmission components and produce a certain high temperature, affecting its lubrication effect. For this reason, we propose a lubricating oil delivery structure for the reducer. Utility Model Content

[0010] As a preferred solution of the present invention, the side surface of the inserting tube is in contact with the inner wall of the oil inlet pipe.

[0011] Compared with the prior art, the advantages of the present invention are: in the present invention, when the lubricating oil lubricates the inner cavity of the reducer body, the lubricating oil in the reducer body is pumped into the inner cavity of the filter box through the oil pump and the oil guide pipe, and the lubricating oil is filtered by the filter mesh in the filter frame, so that the waste debris and impurities in the lubricating oil are filtered out, and the filtered lubricating oil is guided back from the insert tube and the oil inlet pipe to the oil channel inside the reducer body to lubricate the reduction mechanism in the reducer body, realizing the function of transporting the lubricating oil while cleaning the impurities inside it, thereby improving the practicality of the lubricating oil delivery structure for the reducer.
