[0002] In daily life, common household appliances, clocks, etc. can see the application of speed reducers from large-power transmission work to small-load and precise angle transmission. In industrial applications, speed reducers have the functions of speed reduction and torque increase, including worm and worm gear speed reducers. A worm and worm gear speed reducer is a power transmission mechanism that uses a gear speed converter to reduce the rotation speed of the motor to the required rotation speed. During the production of a worm and worm gear speed reducer, it is necessary to inject oil to ensure the smooth operation of the speed reducer.

[0003] At present, when injecting lubricating oil into a speed reducer, the main method is to manually rotate the main shaft of the speed reducer, and then inject lubricating oil into the speed reducer in a squeezing manner through a hand-held oil injection device. This traditional method is not only time-consuming and laborious, but also requires the speed reducer to run in order to make the speed reducer fully lubricated, with low efficiency and extremely inconvenient.

[0016] (2) By using the reciprocating telescopic cylinder, it can drive the push rod reciprocally under the linkage of the linkage seesaw rod, and the push rod drives the suction nozzle block to slide in the negative pressure groove. Thus, under the connection of the negative pressure pipeline and the suction and pressure pipeline, the air inside the oil delivery channel is pumped out, forming a negative pressure state.

The top end of the oil delivery pipe 211 is integrally connected and arranged on the oil delivery channel 114, and one end of the oil spray pipe 212 is connected and arranged with the oil spray nozzle 213. An air suction and pressure channel 214 is arranged inside the speed reduction gear box 111, and the air suction and pressure channel 214 is connected and arranged with the oil delivery channel 114. A blocking block 215 and an air suction and pressure pipe 216 are fixedly installed inside the air suction and pressure channel 214.

By designing the air suction and pressure channel 214, it is used to absorb pressure. Under the matching action with the air suction and pressure pipe 216, the air inside the oil delivery channel 114 is pumped out under the connection of the negative pressure pipe 222 and the air suction and pressure pipe 216, forming a negative pressure state. Furthermore, under the connection of the oil delivery pipe 211, the oil liquid comes up from the oil delivery pipe 211 until it flows into the oil spray pipe 212, and finally sprays out from the oil spray nozzle 213 onto the worm and worm gear, replacing the traditional method of injecting lubricating oil into the speed reducer in a squeezing manner by holding an oil injection device, and improving the oil injection efficiency.
