Abstract
The utility model discloses a large idle gear which comprises a wheel disc that has no surface defects and is subjected to anti-rust treatment, wherein a plurality of gears are respectively arranged on the periphery of the wheel disc, a gear groove is formed between every two adjacent gears, and arc chamfers are respectively arranged on two sides of the bottom of each gear groove; a through hole is formed in the middle of the wheel disc, annular grooves are respectively formed in the front surface and the back surface of the wheel disc around the center through hole, a plurality of through holes are respectively formed in the wheel disc surrounding the center through hole, and an opening groove is formed in the surface of the wheel disc which is arranged between the through holes and the annular grooves; and anti-corrosion layers are arranged on the inner walls of the through holes. The large idle gear has the advantages that the structure is compact, and the large idle gear is small in load, small in vibration and stable in rotating speed in the transmission and operation process; the meshing compactness between the large idle gear and another gear is enhanced, and the transmission effect is improved; the large idle gear and a driving shaft are conveniently assembled and disassembled; and the corrosion resistance of the gear is improved, and the service life of the gear is prolonged.
Description
Technical field
The utility model relates to the part field of air compressor, specifically a kind of large 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.
Large idle gear is the inner common gearing parts of air compressor, and large 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, 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 large idle gear, at the front and back of wheel disc circular groove is set respectively, alleviates the weight of large idle gear, makes it in the transmission operation process, vibrates littlely, and rotating speed is steady; Arc angling is set in teeth groove, strengthens the tightness that meshes between large idle gear and other gears, to improve the transmission effect; In sheave surface fluting is set, comes assembling and the dismounting of convenient large idle gear and live axle.
The technical solution of the utility model is as follows:
A kind of large 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 front and back that centers on through hole wheel disc on every side is respectively equipped with circular groove, is respectively equipped with a plurality of through holes on through hole wheel disc all around, and the sheave surface between through hole and circular groove is provided with fluting; Has corrosion-resistant coating on the inwall of described through hole.
Described large idle gear is characterized in that: described a plurality of through holes be distributed in radially through hole around.
The beneficial effects of the utility model:
The utility model compact structure arranges respectively circular groove at the front and back of wheel disc, has alleviated the weight of large idle gear, makes its load in the transmission operation process little, vibrates littlely, and rotating speed is steady; Arc angling is set in teeth groove, has strengthened the tightness that meshes between large idle gear and other gears, improved the transmission effect; In sheave surface fluting is set, has made things convenient for assembling and the dismounting of large idle gear and live axle, also can be used as the impregnating fluid spout of live axle; In addition, at the inwall of gear center hole corrosion-resistant coating is set, has improved the corrosion resistance of gear, prolonged the working life of gear.
