Abstract
The utility model discloses an idle gear for an air compressor, comprising a wheel disc without defects on a through surface and subjected to rust-proof treatment, wherein a plurality of wheel teeth are arranged around the surrounding edge of the wheel disc, a tooth groove is formed between the two adjacent wheel teeth, and arc chamfers are arranged at the both sides of the bottom of the tooth groove respectively; and a through hole is formed at the middle of the wheel disc, and a plurality of U-shaped key grooves are formed at the ports of the both ends of the through hole respectively. The idle gear for an air compressor disclosed by the utility model is compact in structure, high in accuracy, small in working vibration and low in noise in case of being installed in the air compressor, high in transmission efficiency, long in service life, good in interchangeability, and convenient to assemble and maintain.
Description
Technical field
The utility model relates to the part field of air compressor, specifically a kind of air compressor idle gear.
Background technique
Air compressor is called for short air compressor, is the main body in the compressed air source unit, and it is the device that the mechanical energy of prime mover (normally motor) is converted to the gas pressure energy, is compressed-air actuated pressure generator.
Idle gear is the inner common gearing parts of air compressor, idle gear and axle assembling, be fixed on the axle, be installed in the air compressor, when bent axle drives the piston operation, by crankshaft timing gear and train, wheel shaft drives into exhaust valve and distributor is corresponding with each stroke of motion of piston, to guarantee the operation of air compressor.The idle gear of existing air compressor mounted inside vibrates larger in the course of the work, produces a large amount of noises when causing work, for a long time can be so that the wearing and tearing between the gear be larger, and transmission occurs loosening, thereby has influence on the normal operation of air compressor.
The model utility content
The purpose of this utility model provides a kind of air compressor idle gear, to make things convenient for the assembling between gear and the rotating shaft, reduces wearing and tearing each other; In addition, arc angling is set in teeth groove, strengthens the tightness that meshes between the gear, improve the transmission effect.
The technical solution of the utility model is as follows:
A kind of air compressor idle gear, include by surperficial zero defect and carry out antirust processing wheel disc, edge, surrounding around wheel disc has a plurality of gear teeth respectively, and it is characterized in that: have teeth groove between adjacent two gear teeth, the both sides of described teeth groove bottom land are respectively equipped with arc angling; The middle part of described wheel disc is provided with through hole, and the port at described through hole two ends is respectively equipped with a plurality of U-shaped keyways.
Described air compressor idle gear is characterized in that: have rotating shaft from through hole, pass and with the through hole interference fit.
The beneficial effects of the utility model:
The utility model compact structure, precision is high, and it is little to be contained in the air compressor operational vibration, and noise is low, and transmission efficiency is high, long service life, interchangeability is good, assembling and easy to maintenance.

Fig. 3 is the enlarged diagram of the utility model I part-structure.
Embodiment
Referring to accompanying drawing, a kind of air compressor idle gear includes by surperficial zero defect and carries out antirust processing wheel disc 1, around the surrounding of wheel disc 1 along having respectively a plurality of gear teeth 2, have teeth groove 3 between adjacent two gear teeth, the both sides of teeth groove 3 bottom lands are respectively equipped with arc angling 4; The middle part of wheel disc 1 is provided with through hole 5, and the port at through hole 5 two ends is respectively equipped with two U-shaped keyways 6, has made things convenient for assembling and maintenance between gear and the rotating shaft.
In the utility model, have rotating shaft from through hole 5, pass and with the through hole interference fit.
Claims (2)
