Abstract
The utility model discloses an idle gear assembly of an air compressor. The idle gear assembly comprises a gear disc and a plurality of gear teeth; surfaces of the gear disc are defect-free, the gear disc is subjected to rustproof treatment, the gear teeth surround the peripheral edge of the gear disc, a tooth socket is arranged between each two adjacent gear teeth, and arc-shaped chamfers are respectively arranged on two sides of the bottom of each tooth socket; and a through hole is arranged in the middle of the gear disc, and a bushing is sleeved in the through hole. The idle gear assembly is compact in structure and high in precision, the bushing is sleeved in the central hole of an idle gear of the air compressor to form the assembly at first, then the assembly is assembled with a shaft, the assembly and the shaft are arranged in the air compressor, are matched with a screw in a cylinder and rotate with the screw in the cylinder, working vibration and noise are low, transmission is stable, and the normal running of the air compressor is guaranteed.
Description
Technical field
The utility model relates to the part field of air compressor, specifically a kind of air compressor 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.
Idle gear is the inner common gearing parts 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 assembly, first lining is enclosed within the center hole of air compressor idle gear and forms assembly, with assembly and axle assembling, be contained in the air compressor again, 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 air compressor idle gear assembly, 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, is set with lining in the described through hole.
Described air compressor idle gear assembly is characterized in that: the port at described through hole two ends is respectively equipped with a plurality of U-shaped keyways.
The beneficial effects of the utility model:
The utility model compact structure, precision is high, first lining is enclosed within the center hole of air compressor idle gear and forms assembly, assembly and axle is assembled again, be contained in the air compressor, be engaged in the cylinder with screw rod and rotate, operational vibration is little, noise is low, and transmission is stable, has guaranteed the normal operation of air compressor.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the enlarged diagram of the utility model gear teeth and tooth slot structure.
Embodiment
Referring to accompanying drawing, a kind of air compressor idle gear assembly 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, is set with lining 6 in the through hole 5.
In the utility model, the port at through hole 5 two ends is respectively equipped with two U-shaped keyways 7, has made things convenient for assembling and maintenance between gear and the rotating shaft.
