Abstract
The utility model discloses a rust-proofing gear comprising a gear body. Several gear teeth is distributed on the annular outer wall of the gear body. The annual inner wall of a center hole of the gear body is provided with rectangular key grooves. The front surface and the back surface of the gear body are respectively provided with grooves which correspond to each other. The grooves which correspond with each other are communicated through the center hole. The outer wall of the gear body is provided with a rust-proofing layer. The rust-proofing gear is simple in structure. A plating finish design is adopted, so the rust-proofing ability of the rust-proofing gear is improved. Besides, the design of the grooves which are arranged on the front surface and the back surface of the gear is adopted, so the weight of the gear is reduced. Therefore, the gear is more stable and more reliable in the process of transmission, and the normal transmission work is guaranteed.
Description
Technical field
The utility model relates to field of gears, specifically a kind of rust-proofing gear.
Background technique
Gear is common gearing parts.Upward become rusty easily because gear is exposed in the air, affect the transmission effect of gear.In addition, after the assembling of gear and axle, because gear is solid construction, so it vibrates greatlyr in the course of the work, produces a large amount of noises when causing work, even causes between gear and the axle and misplace, thereby has influence on normal transmission work.
The model utility content
The utility model has overcome the defective in the prior art, and a kind of rust-proofing gear is provided, and its rust-proofing ability strengthens, and more stable during work, noise is little.
The technical solution of the utility model is as follows:
A kind of rust-proofing gear, include gear mass, be distributed with some gear teeth on the annular outer wall of gear mass, the annular inner wall of gear mass center hole is provided with the rectangle keyway, it is characterized in that: the front and back of wheel disc is respectively equipped with the groove of mutual correspondence on the described gear mass, is communicated with by center hole between the corresponding groove; The outer wall of described gear mass is provided with the rust-proofing layer.
A kind of rust-proofing gear is characterized in that: described rust-proofing layer is electrodeposited coating.
The beneficial effects of the utility model:
The utility model is simple in structure, design by electrodeposited coating, improved rust-proofing ability of the present utility model, in addition, the design of the front and back groove of wheel disc has alleviated the weight of gear, so that gear is more stable, reliable in transmission process, reduce noise, guaranteed normal transmission work.
