Abstract

The utility model discloses an air compressor gear with a cross hole. The air compressor gear comprises a gear wheel with a circular through hole at the center, four rectangular through holes are connected to the edge of the circular through hole, and the four rectangular through holes and the circular through hole form the cross hole. The air compressor gear with the cross hole is simple in structure and easy to implement. With the cross hole, close fit between the gear and a gear shaft can be realized, and stability in running of the air compressor gear is improved greatly.

Description

A kind of air compressor gear of cruciform vent
Technical field
The utility model relates to field of gears, is specially a kind of air compressor gear of cruciform vent.
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.Prior art air compressor Gear center mounting hole mostly is circular hole, is combined with the gear shaft of circular shaft shape and is prone to the not problem of close-fitting, affects the normal operation of gear.
The model utility content
The utility model purpose provides a kind of air compressor gear of cruciform vent, is combined the not problem of close-fitting that is prone to gear shaft with prior art air compressor gear.
In order to achieve the above object, the technological scheme that adopts of the utility model is:
A kind of air compressor gear of cruciform vent, include wheel disc, wheel disc dish edge forms a plurality of gear teeth, it is characterized in that: the described disk center of taking turns is provided with manhole, be positioned at and be connected with four rectangular through-hole that evenly distribute and arrange along the wheel disc radials on the manhole edge, four rectangular through-hole and manhole formation cruciform vent.
The air compressor gear of described a kind of cruciform vent is characterized in that: also be provided with four equally distributed threaded mounting holes on the described wheel disc.
The utility model is simple in structure, is easy to realize that the gear hole of gear is set to cruciform vent, cooperates with the gear shaft of cross along the limit, can realize close-fitting between gear and the gear shaft, has greatly improved air compressor gear operation stability.
