Abstract
The utility model discloses an idle gear component which comprise a large idle gear and a small idle gear. The small idle gear is nested in the central hole of the large idle gear. Gear teeth of the larger idle gear and the small idle gear are staggered. The front side and the rear side of a large idle gear disc around the small idle gear are provided with annular grooves respectively. The annular groove on the front side of the large idle gear disc is communicated with that on the rear side of the large idle gear disc through a plurality of through holes. A lining is sleeved on the inner wall of the central hole of the small idle gear. An upper retaining strip and a lower retaining strip are integrally formed on two sides of the inner wall of the lining by means of vulcanization. The idle gear component has the advantages that the idle gear component is reasonable in structure, the large idle gear and the small idle gear are closely matched with a shaft, weight of the component is reduced by the annular grooves arranged on the front side and the rear side of the large idle gear, and accordingly, the component is low in vibration and noise and stable in transmission, and normal operation of an air compressor is guaranteed.
Description
Technical field
The utility model relates to the part field of air compressor, specifically a kind of idle gear assembly.
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.
The idle gear assembly is the inner common gearing parts of air compressor.The idle gear assembly of existing air compressor mounted inside vibrates larger in the course of the 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 idle gear assembly, first large and small idle gear is fitted together, then lining is enclosed within the center hole of little idle gear and forms assembly, again with assembly and axle assembling, be contained in the air compressor, be engaged in the cylinder with screw rod and rotate, to guarantee the normal operation of air compressor.
The technical solution of the utility model is as follows:
A kind of idle gear assembly, include large and small idle gear, it is characterized in that: described little idle gear is sleeved in the center hole of large idle gear, and the gear teeth of large and small idle gear stagger mutually, the front and back that is centered around little idle gear large idle gear wheel disc on every side is respectively equipped with annular groove, is connected by a plurality of through holes between the annular groove on the large idle gear wheel disc front and back; Be set with lining on the center bore inner wall of described little idle gear, the both sides of described lining inwall have respectively the upper and lower blend stop of integrated vulcanizing moulding.
2, idle gear assembly according to claim 1 is characterized in that: have live axle from lining, to pass and with the lining interference fit.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, cooperates between large and small idle gear and the axle closely, and the annular groove that the front and back of large idle gear wheel disc arranges has respectively alleviated the weight of assembly, so that the operational vibration of assembly is little, noise is low, and transmission is stable, thereby has guaranteed the normal operation of air compressor.

Embodiment
Referring to accompanying drawing, a kind of idle gear assembly, include large and small idle gear 1,2, little idle gear 2 is sleeved in the center hole of large idle gear 1, and large and small idle gear 1,2 the gear teeth stagger mutually, the front and back that is centered around the wheel disc of little idle gear 2 large idle gear 1 on every side is respectively equipped with annular groove 3, is connected by four through holes 4 between the annular groove 3 on the wheel disc front and back of large idle gear 1; Be set with lining 5 on the center bore inner wall of little idle gear 2, the both sides of lining 5 inwalls have respectively the upper and lower blend stop 6 of integrated vulcanizing moulding.
In the utility model, have live axle from lining 5, to pass and with lining 5 interference fit.
Claims (2)
1. idle gear assembly, include large and small idle gear, it is characterized in that: described little idle gear is sleeved in the center hole of large idle gear, and the gear teeth of large and small idle gear stagger mutually, the front and back that is centered around little idle gear large idle gear wheel disc on every side is respectively equipped with annular groove, is connected by a plurality of through holes between the annular groove on the large idle gear wheel disc front and back; Be set with lining on the center bore inner wall of described little idle gear, the both sides of described lining inwall have respectively the upper and lower blend stop of integrated vulcanizing moulding.
