Abstract
The utility model discloses a small idle gear of an air compressor, which comprises a gear disc that is free from surface defects and is subjected to anti-rust treatment; a plurality of gear teeth are respectively arranged at the edge around the gear disc; a through hole is formed in the middle of the gear disc; the front and the back of the gear disc around the through hole are respectively provided with a ring-shaped groove; a plurality of open slots are respectively arranged on the surface of the gear disc between the through hole and the ring-shaped grooves; and an anti-corrosion layer is arranged on the inner wall of the through hole. The small idle gear of the air compressor is compact in structure and corrosion-resistant; the front and the back of the gear disc are respectively provided with the ring-shaped groove, so that the weight of the small idle gear of the air compressor can be lightened, and the small idle gear of the air compressor is less in load, small in vibration, low in noise and stable in rotating speed in the transmission operation process; furthermore, the plurality of open slots are respectively arranged on the surface of the gear disc, so that the assembly and disassembly between the small idle gear of the air compressor and a driving shaft can be conveniently carried out, and the open slots also can be used as anti-corrosion liquid injection holes of the driving shaft.
Description
Technical field
The utility model relates to the part field of air compressor, specifically the little idle gear of a kind of air compressor.
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.
Little idle gear is the inner common gearing parts of air compressor, and little idle gear and live axle assembling are fixed on the axle, are contained in the air compressor, is engaged in the cylinder with screw rod and rotates, to guarantee the air compressor running.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, thereby has influence on the normal operation of air compressor.
The model utility content
The purpose of this utility model provides the little idle gear of a kind of air compressor, at the front and back of wheel disc circular groove is set respectively, alleviates the weight of the little idle gear of air compressor, makes its load in the transmission operation process little, vibrates littlely, and rotating speed is steady; In sheave surface a plurality of flutings are set, make things convenient for assembling and the dismounting of the little idle gear of air compressor and live axle.
The technical solution of the utility model is as follows:
The little idle gear of a kind of air compressor, include by surperficial zero defect and carry out antirust processing wheel disc, edge, surrounding around wheel disc has respectively a plurality of gear teeth, it is characterized in that: the middle part of described wheel disc is provided with through hole, front and back around through hole wheel disc on every side is respectively equipped with circular groove, and the sheave surface between through hole and circular groove is respectively equipped with a plurality of flutings; Has corrosion-resistant coating on the inwall of described through hole.
The little idle gear of described air compressor 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, corrosion-resistant, at the front and back of wheel disc circular groove is set respectively, alleviated the weight of the little idle gear of air compressor, make its load in the transmission operation process little, vibrate littlely, reduced noise, rotating speed is steady; In addition, in sheave surface a plurality of flutings are set respectively, have made things convenient for assembling and the dismounting of the little idle gear of air compressor and live axle, also can be used as the impregnating fluid spout of live axle.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, the little idle gear of a kind of air compressor, include by surperficial zero defect and carry out antirust processing wheel disc 1, edge, surrounding around wheel disc 1 has respectively a plurality of gear teeth 2, the middle part of wheel disc 1 is provided with through hole 3, front and back around through hole 3 wheel disc 1 on every side is respectively equipped with circular groove 4, and wheel disc 1 surface between through hole 3 and circular groove 4 is respectively equipped with three flutings 5; Has corrosion-resistant coating 6 on the inwall of through hole 3.
In the utility model, have rotating shaft from through hole 3, pass and with through hole 3 interference fit.
Claims (2)
1. little idle gear of air compressor, include by surperficial zero defect and carry out antirust processing wheel disc, edge, surrounding around wheel disc has respectively a plurality of gear teeth, it is characterized in that: the middle part of described wheel disc is provided with through hole, front and back around through hole wheel disc on every side is respectively equipped with circular groove, and the sheave surface between through hole and circular groove is respectively equipped with a plurality of flutings; Has corrosion-resistant coating on the inwall of described through hole.
