AI Technical Summary
The existing eccentric gear lacks dustproof devices, which causes external dust to easily enter the openings and gaps of the gears when not in use, causing wear.
An eccentric gear with a dustproof mechanism is designed, including a dustproof mechanism and a limiting mechanism. The dustproof mechanism consists of a circular plate, a sealing plug and a clamp. The sealing plug extends into the inner part of the body and is connected to the circular plate. The block blocks the gap between the outer wall, and the limiting mechanism is used to control the separation between the dustproof mechanism and the body.
Effectively prevent external dust from entering the gear, avoid wear, and when needed, the dustproof mechanism can be easily separated through the limiting mechanism to ensure the normal operation of the gear.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of eccentric gears, in particular to an eccentric gear with a dustproof mechanism. Background Art
[0002] As we all know, eccentric gears are a special gear system in which the axis (center) of the gear does not coincide with the center of the gear itself, but is offset by a certain distance. This design allows the gear to produce eccentric motion when it rotates. Eccentric gears are usually used to convert rotational motion into linear motion or change the rate or direction of motion.
[0003] However, the existing eccentric gears generally do not have dustproof devices. When the eccentric gears are not in use or are stored, dust from the outside can easily enter the openings and gaps of the eccentric gears due to the lack of dustproof devices. This can easily lead to the eccentric gears being worn by dust particles because the dust particles are not cleaned during use. Utility Model Content
