Description

Technical Field

[0001] The utility model relates to a novel gear structure used for speed reducer transmission, belonging to the technical field of speed reducers. Background Art

[0002] The reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive 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 speed and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.

[0003] For example, CN212616120U discloses a novel gear structure for reducer transmission, wherein the buckle groove buckles the drawstring from the inlay groove of the cover head, and the two drawstrings are used to pull the rubber plug out of the connection hole, so that the reducer can be installed. The beneficial effect is that the connection hole and the plug hole are sealed by a convenient sealing device, so that dust and gravel will not enter the reducer before installation. Then, by buckling the drawstring from the inlay groove of the cover head, it is convenient for the staff to grab the drawstring to drive the rubber plug connected to the cover head to pull it out from the connection hole and the plug hole, which is very fast and labor-saving. However, the worm end of the reducer is generally connected to a sleeve, and the convenient sealing device can only seal the connection hole and the plug hole, and cannot protect the outer area of ​​the sleeve. In the event of a collision, the sleeve is easily damaged, and during the use of the reducer, when the worm and the gear rub, metal debris will be generated due to friction. When the metal debris is mixed in the lubricating oil, the friction between the worm and the gear will increase, affecting the service life of the worm and the gear. Utility Model Content

By arranging a sealing sleeve, the sealing sleeve can not only seal the shaft sleeve, but also protect the outside of the shaft sleeve to prevent the shaft sleeve from being damaged due to collision and deformation. An oil box and a magnetic plate are provided at the bottom of the shell. The magnetic plate can absorb metal debris in the lubricating oil, thereby reducing the metal debris from following the lubricating oil and adhering to the worm and gear, preventing the metal debris from generating additional friction on the worm and gear and affecting the service life of the worm and gear, so as to solve the problems raised in the above-mentioned background technology.
