Abstract
The utility model discloses a camshaft gear. The camshaft gear comprises a gear disc which is non-defective in surface and subjected to rust-proof treatment, a plurality of gear teeth are arranged at the peripheral edge of the gear disc respectively, a through hole is arranged in the middle of the gear disc, a plurality of hole ring groups are arranged on the gear disc on the periphery of the through hole from inside to outside respectively, each hole ring group comprises a plurality of holes which are radially distributed on the periphery of the through hole, annular grooves are arranged on the front and the back of the gear disc on the periphery of the through hole, the bottom surface of each annular groove is a conical surface, and a positioning hole is arranged on the gear disc positioned on the side of the through hole. The camshaft gear is compact in structure, and the annular grooves and the hole rings are arranged on the gear disc, so that the gear is lightened while noise is reduced to enable rotational speed during transmission operation of the gear to be stable; and additionally, by the aid of the positioning hole arranged on the gear, assembly of the gear and a camshaft is facilitated, misplacement between the gear and the camshaft is prevented, 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 camshaft gear wheel.
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.
Gear is the inner common gearing parts of air compressor.The 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.In addition, because wearing and tearing misplace between gear and the camshaft, thereby have had influence on the normal transmission work of gear.
The model utility content
The purpose of this utility model provides a kind of camshaft gear wheel, with the assembling of actuated by cams axle, and is contained in the air compressor, is engaged in the cylinder with screw rod and rotates, to guarantee the normal operation of air compressor.
The technical solution of the utility model is as follows:
A kind of camshaft gear wheel, 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, on through hole wheel disc all around, be respectively equipped with from inside to outside many groups holes circle, every group of hole circle comprises respectively by a plurality of perforates that are distributed in radially around the through hole and forming, and the front and back of the wheel disc around the through hole is respectively equipped with circular groove, and the bottom surface of described circular groove is conical surface; The wheel disc that is positioned at through hole one side is provided with positioning hole.
Described camshaft gear wheel is characterized in that: in the circle of described many groups hole, be positioned at the most inboard hole circle and include six perforates, be positioned at outermost hole circle and include four perforates.
The beneficial effects of the utility model:
The utility model compact structure arranges circular groove and Kong Quan at wheel disc, has alleviated the weight of gear, has reduced noise, makes it steady at transmission operation process medium speed; In addition, at gear positioning hole is set, has made things convenient for the assembling of gear and camshaft, prevented from misplacing between gear and the camshaft, guaranteed the normal operation of air compressor.
