Abstract
The utility model discloses an air compressor gear structure which comprises a gear disc. A central boss is disposed on each of the front disc face and the rear disc face of the gear disc. A plurality of gear teeth are disposed along the rear ring face and at the edge of the gear disc. The central boss of the front disc face is provided with a seal groove. The central boss of the rear disc face is provided with a mounting hole of a conical column shape. A seal ring is disposed in the seal groove. The air compressor gear structure is simple in structure and easy to implement, strength of the gear can be improved effectively, the service life of the gear is prolonged, and work stability of an air compressor is improved.
Description
Technical field
The utility model relates to field of gears, is specially a kind of air compressor gear structure.
Background technique
Air compressor be a kind of with mechanical energy change into gas pressure can device, in air compressor, adopt and must transmit motion state with a plurality of components of machine, its middle gear is the component of machine of commonly using.The gear teeth of prior art gear mostly are suspended type, gear teeth easy-rupturing, and combination is not tight between gear and the gear shaft, easily causes gear shaft idle running.
The model utility content
The utility model purpose provides a kind of air compressor gear structure, and solving prior art air compressor gear tooth easy-rupturing, gear is combined untight problem with gear shaft.
In order to achieve the above object, the technological scheme that adopts of the utility model is:
A kind of air compressor gear structure, include wheel disc, it is characterized in that: be respectively arranged with central boss on the forward and backward card of wheel disc, wheel disc Pan Yuanchu is provided with the ring edge, be positioned on the rear anchor ring on wheel disc Pan Yuanchu ring edge and be provided with a plurality of gear teeth around wheel disk center, the card central boss has seal groove before the described wheel disc in wheel disc, the card central boss has the mounting hole of boring column behind the wheel disc in wheel disc, and the nose end that the mounting hole area is less is connected to seal groove bottom land neutral position, is arranged in seal groove and is provided with seal ring with the mounting hole form fit.
Described a kind of air compressor gear structure is characterized in that: the upper cardiac prominence platform of the front card of described wheel disc diameter greater than wheel disc after the upper cardiac prominence platform of card diameter.
The utility model is simple in structure, be easy to realize, the gear teeth of gear are opened at ring along on the rear anchor ring, utilize ring on the wheel disc along as backrest, the intensity of the energy Effective Raise gear teeth, postpone the working life of the gear teeth, mounting hole and the seal ring of boring simultaneously column can improve gear and gear shaft bonding tightness, and then have improved air compressor working gear stability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1.A kind of air compressor gear structure, include wheel disc 1, be respectively arranged with central boss on the wheel disc 1 forward and backward card, wheel disc 1 Pan Yuanchu is provided with ring along 2, be positioned at wheel disc 1 Pan Yuanchu ring along being provided with a plurality of gear teeth 3 around wheel disc 1 center on 2 the rear anchor ring, wheel disc 1 front card central boss 4 has seal groove 5 in wheel disc 1, wheel disc 1 rear card central boss 6 has the mounting hole 7 of boring column in wheel disc 1, and the nose end that mounting hole 7 areas are less is connected to seal groove 5 bottom land neutral positions, is arranged in seal groove 5 and is provided with seal ring 8 with mounting hole 7 form fit.Upper cardiac prominence platform 4 diameters of wheel disc 1 front card are greater than upper cardiac prominence platform 6 diameters of wheel disc 1 rear card.
