Abstract
The utility model discloses an air compressor gear with the function of preventing axial play. The air compressor gear comprises a disk which is provided with a central through hole in the center, a pair of curved rigid rubber sleeves are arranged in the central through hole respectively, each rigid rubber sleeve is provided with a through hole screwed up to the center, and a sleeve body on the periphery of the through hole of the each rigid rubber sleeve is embedded in the side wall of the through hole of the disk. The air compressor gear with the function of preventing axial play is simple in structure and easy to implement, the gear can be effectively prevented from axial play on a gear shaft, and operation stability of the air compressor gear is improved.
Description
Technical field
The utility model relates to field of gears, is specially a kind of air compressor gear of anti-axial float.
Background technique
Air compressor be a kind of with mechanical energy change into gas pressure can device, in air compressor, must transmit motion state with a plurality of components of machine, its middle gear is the component of machine of commonly using.During prior art air compressor gear operation, the axial float on gear shaft is larger, and it is larger to cause gear to be beated, and affects air compressor working gear stability.
The model utility content
The utility model purpose provides a kind of air compressor gear of anti-axial float, to solve the larger problem of prior art air compressor gear axial float.
In order to achieve the above object, the technological scheme that adopts of the utility model is:
A kind of air compressor gear of anti-axial float, include wheel disc, wheel disc one end is provided with the ring platform, ring platform sidewall forms the multiple tracks gear teeth, it is characterized in that: wheel disk center is provided with the central through bore that runs through wheel disc and ring platform, and be provided with a pair of curved rigidity rubber sleeve that is respectively in the central through bore of wheel disc, each rigidity rubber sleeve has respectively consistent and that screw to center through hole with wheel disc central through bore diameter, the cover status of each rigidity rubber sleeve bore periphery is not embedded in the wheel disc central through bore sidewall, and two rigidity rubber sleeve curved parts are mutually close.
The utility model is simple in structure, be easy to realize, be provided with the rigidity rubber sleeve in the central through bore, the through hole of two rigidity rubber sleeves screws to the center respectively, and has each other mutually close curved part, utilize two rigidity rubber sleeves can make gear and gear shaft close-fitting and locking teeth wheel shaft, can effectively prevent the axial float of gear on gear shaft, improved air compressor working gear stability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
