Abstract

The utility model relates to the technical field of machine, and particularly relates to a de-noising heat radiation type gear. The gear comprises a gear ring, a gear tooth and a shaft hole; the gear tooth is arranged on the gear ring; the shaft hole is formed in the middle of the gear ring; a damping groove is formed in the lateral face of the gear ring; a damping heat radiation layer is arranged inside the damping groove; the damping groove is annular and has the same circle center with the shaft hole; the damping heat radiation layer is made of heat radiation silica rubber; the gear can be used for effectively reducing vibration in operation and can be used for controlling temperature in an assisting manner, so that inclination caused by deformation due to high temperature can be avoided. Therefore, the purpose of de-noising can be reached well; the service life of the gear is prolonged; the cost is saved; and the effect can be improved.

Description

A kind of noise abatement heat radiating type gear

Technical field

The utility model relates to a kind of field of mechanical technique, especially a kind of noise abatement heat radiating type gear.

Background technique

Gear is a kind of common mechanical transmission part, in the process of transmission, because the result of many factors comprehensive function produces noise, shake, abate the noise, method commonly used is for optimizing the design of gears parameter, optimize profile of tooth, or improve manufacturing process, improve the Gear Processing precision, reduce alignment error etc., difficulty is large when improving, and has greatly increased the cost that manufactures and designs, and utilizes more in addition foam-filled thing to reduce the gear of vibrations, then effect is also not obvious, and can't solve heat dissipation problem.

The model utility content

In order to overcome the deficiency of existing gear vibration-damping radiating weak effect, the utility model provides a kind of noise abatement heat radiating type gear.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of noise abatement heat radiating type gear, comprise gear ring, teeth and axis hole, and gear ring is provided with teeth, is provided with axis hole in the middle of the gear ring, and the gear ring side is provided with damping trough, is provided with the vibration-damping radiating layer in the damping trough.

According to another embodiment of the present utility model, further comprise damping trough be the annular, and with the same center of circle of axis hole.

According to another embodiment of the present utility model, comprise that further the vibration-damping radiating layer is heat radiation silicone rubber.

The beneficial effects of the utility model are, vibrations when this gear can effectively reduce its operation, and can help its control temperature, thereby and be unlikely to because high temperature generation deformation cause canting, well reached the purpose of noise abatement, improve the life-span of gear, saved cost, improved effect.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a kind of structural representation of noise abatement heat radiating type gear;

1. gear rings among the figure, 2. teeth, 3. axis hole, 4. damping trough, 5. vibration-damping radiating layer.

Embodiment

A kind of structural representation of noise abatement heat radiating type gear such as Fig. 1, a kind of noise abatement heat radiating type gear, comprise gear ring 1, teeth 2 and axis hole 3, gear ring 1 is provided with teeth 2, is provided with axis hole 3 in the middle of the gear ring 1, and gear ring 1 side is provided with damping trough 4, be provided with vibration-damping radiating layer 5 in the damping trough, damping trough 4 is annular, and with the axis hole 3 same centers of circle, vibration-damping radiating layer 5 is heat radiation silicone rubber.

Axis hole 3 outers at gear 1 arrange a ring annular groove, be damping trough 4, in damping trough, insert vibration-damping radiating layer 5, and the material of vibration-damping radiating layer is heat-conducting silica gel sheet, its material is soft and have elasticity, vibrations that can the absorption portion gear, thereby reach the purpose of noise abatement, and the heat dispersion of heat-conducting silica gel sheet can absorb the heat of gear, make gear under running up, be unlikely to occur because of high temperature deformation, thereby stop it to produce noise because of canting, the vibrations when this gear can effectively reduce its operation, and can help its control temperature, thereby and be unlikely to because high temperature generation deformation cause canting, well reached the purpose of noise abatement, improved the life-span of gear, save cost, improved effect.
