Description

Technical Field

[0001] The utility model relates to the technical field of reducer oil replacement, and more specifically, to an oil injection mechanism for a reducer. Background Art

[0002] The reducer is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery. Reducers are generally used for transmission equipment with low speed and high torque. The power of the motor, internal combustion engine or other high-speed operation is reduced by meshing the gear with a small number of teeth on the input shaft of the reducer with the large gear on the output shaft. Ordinary reducers also have several pairs of gears with the same principle to achieve the ideal reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio. The reducer plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator. It is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It has many types and different models, and different types have different uses.

[0003] When the robot body is maintained, the reducer needs to be lubricated and replaced. In the prior art, an oil pump is often used to absorb the lubricating oil of the reducer and then inject it into the oil inlet hole of the reducer. When filling oil, the oil filling gun head is directly aimed at the oil filling port of the reducer for oil filling. If the docking angle deviates during oil filling, the injected grease will overflow, resulting in a waste of lubricating oil. In addition, one person is required to always aim at the oil inlet hole, which increases the cleaning time and maintenance difficulty of the maintenance personnel.

[0004] For example, a Chinese patent (publication number: CN217130296U) discloses a semi-automatic belt conveyor reducer oil changing device, and its specification discloses: pour the oil into the oil barrel 1, move the entire device to the reducer and the coupler, first discharge the old oil in the reducer and the coupler, and then insert the oil outlet nozzle 31 into the oil port of the reducer and the coupler, the air pump works, the air flow enters the oil barrel 1, the air flow blows the oil in the oil barrel 1 into the oil outlet nozzle 31, and flows out, enters the reducer and the coupler, and completes the refueling; when the oil storage tank is high and it is inconvenient to pour oil into the oil barrel 1, the oil outlet nozzle 31 can be inserted into the oil storage tank, the pump rotates in the opposite direction, the air in the oil barrel 1 is sucked out, the oil is sucked from the oil storage tank, and then the reducer and the coupler are filled with oil through the oil outlet nozzle 31. The above patent can prove the defects of the prior art. Utility Model Content

[0051] Further, such as Figure 6-Figure 7 As shown, the oil outlet portion includes an oil drain pipe 205, and third threaded joints 206 are respectively connected to both ends of the oil drain pipe 205. The third threaded joint 206 is provided with threads at one end away from the oil drain pipe 205, and is threadedly connected to the oil outlet of the reducer through the third threaded joint 206, so that there is no need to hold the third threaded joint 206 by hand when draining oil.

[0053] When in use, firstly, the second threaded joint 111 is threadedly connected with the oil inlet hole of the reducer, and then the third threaded joint 206 is connected with the oil outlet hole of the reducer, the three-way pipe 107 is connected with the compressed air source through the pipeline, and the second speed regulating valve 109 is opened, so that the compressed air passes through the three-way pipe 107, the fourth connecting pipe 108, the second speed regulating valve 109, the fifth connecting pipe 110 and the second threaded joint 111 to inflate the reducer, and the waste oil in the reducer flows into the waste oil collection barrel 201 through the third threaded joint 206 and the oil drain pipe 205.
