Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reducers, in particular to a wear-resistant gapless reducer. Background Art
[0002] A backlash-free reducer is a precision machine that has a good match between the worm wheel and the worm, and plays the role of matching the speed and transmitting torque between the prime mover and the working machine or actuator. Backlash-free reducers are mostly used in high-precision equipment, and generally have no backlash in the return stroke.
[0003] After searching, the patent announcement number CN220600416U discloses a wear-resistant gapless reducer, including: a main body, an oil box and a compression chamber. A rotating shaft is provided in the center of the front of the main body, and an oil box is provided on the top of the main body. The bottom of the oil box is welded and fixed to the top of the main body. Compared with the prior art, the utility model has the following beneficial effects: by arranging a dial plate, a compression chamber, a telescopic head, a pressure plate, a spring and a connecting pipe, the dial head squeezes the telescopic head to compress the pressure plate inward, and the pressure plate moves upward inside the compression chamber, thereby increasing the air pressure inside the compression chamber, and then increasing the air pressure inside the oil chamber through the connecting pipe. By arranging an oil chamber, an oil delivery pipe and a nozzle, when the air pressure inside the oil chamber increases, the lubricating oil is squeezed from the inside of the oil chamber into the inside of the oil delivery pipe, and is transported from the inside of the oil delivery pipe to the nozzle, and the nozzle sprays the lubricating oil to the rotating shaft, thereby achieving the effect of lubricating the rotating shaft, thereby reducing friction, slowing down the wear of the rotating shaft, and making the rotating shaft rotate more stably.
[0004] However, this patent still has some shortcomings. In actual use, this patent mainly uses the lubricating oil in the oil box to lubricate the internal structure of the reducer. However, the oil box does not have a component that can monitor and remind the remaining lubricating oil. When the staff fails to add lubricating oil in time, the internal components of the reducer will lose the lubrication effect, thereby causing a malfunction. In addition, when the oil tank in this patent is filled with lubricating oil, the threaded oil cap needs to be turned multiple times to open and close the oil filling port, which is very troublesome to operate and use. If it is turned too much, it will cause the oil cap to be damaged and cannot be used. Therefore, it is necessary to improve it.
[0005] To this end, we proposed a wear-resistant, backlash-free reducer. Utility Model Content

[0023] The top ends of the two springs 16 are fixedly mounted on the slide 18, and the bottom ends of the two springs 16 are fixedly mounted on the bottom end of the filling seat 4. This design is conducive to the use of the present device. Oil outlet holes 14 are provided on both sides of the sealing seat 13, and the oil outlet holes 14 facilitate the lubricating oil to enter the oil tank 2. An alarm 6 is fixedly installed on the top of the oil tank 2, which is located on the right side of the PLC controller 5.
