Abstract
The utility model discloses an air compressor drive gear which comprises a disk with a central projection. The inner wall of a central through hole of the central projection, facing to the rear surface of the disk, is provided with a plurality of raised points, and seal rings are disposed on the hole surfaces of two ends of the central through hole. The air compressor drive gear is simple in structure, easy to implement, free of idling and less corroded.
Description
Technical field
The utility model relates to field of gears, is specially a kind of air compressor actuation gear.
Background technique
Air compressor be a kind of with mechanical energy change into gas pressure can device, in air compressor, must adopt actuation gear transmit motion state.Exist in conjunction with not tight between prior art actuation gear and the gear shaft, the problem that sealing is poor causes being prone to idle running between gear and the gear shaft problem that gear easily is corroded.
The model utility content
The utility model purpose provides a kind of air compressor actuation gear, has idle running, the problem that easily is corroded to solve prior art air compressor actuation gear.
In order to achieve the above object, the technological scheme that adopts of the utility model is:
A kind of air compressor actuation gear, include wheel disc, be provided with the gear teeth on the wheel disc dish edge, it is characterized in that: card is provided with boss before the described wheel disc, card has central through bore after from boss to wheel disc, the central through bore inwall is provided with a plurality of salient points, and card is provided with seal ring after being positioned at central through bore two stomidium face places and being close to respectively boss and wheel disc.
The utility model is simple in structure, be easy to realize, utilize a plurality of salient points realization gears of central through bore inwall and the close-fitting between the gear shaft, avoided the problem of gear idle running, utilize simultaneously the seal ring of central through bore two stomidium face settings can improve the sealing of gear, reduce the degree that gear is corroded.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1.A kind of air compressor actuation gear, include wheel disc 1, be provided with the gear teeth on the wheel disc 1 dish edge, wheel disc 1 front card is provided with boss 2,1 rear card has central through bore 3 from boss 2 to wheel disc, central through bore 3 inwalls are provided with a plurality of salient points 4, are positioned at that boss 2 is close to respectively at 3 liang of stomidium faces of central through bore place and wheel disc 1 rear card is provided with seal ring 5.
