Abstract
The utility model discloses a steering pump gear which comprises a gear wheel. A plurality of teeth are arranged at the peripheral edge of the gear wheel and covered with an wear layer, a slot is formed between each two adjacent teeth, arc chamfers are respectively arranged on two sides of the bottom of each slot, a through hole is arranged in the middle of the gear wheel, a plurality of damping holes are arranged around the through hole on the gear wheel, and the inner wall of the through hole is provided with an anticorrosion layer. The steering pump gear is reasonable in structure. Since the arc chamfers are arranged in the slots, and the wear layers are arranged on the surfaces of the teeth, tightness of meshing between the steering pump gear and the other gear is improved. By the damping holes arranged on the gear wheel, stability in transmission of the gear is improved and normal transmission is guaranteed. Owing to the anti-corrosion layer arranged on the inner wall of the center hole of the gear wheel, corrosion resistance of the steering pump gear is improved.
Description
Technical field
The utility model relates to the part field of steering pump, specifically a kind of steering pump gear.
Background technique
Steering pump claims again automobile booster pump, mainly is to assist the driver to do the automobile steering adjustment, alleviates the force intensity of using of beating steering wheel for the driver.
The steering pump gear is the inner common gearing parts of steering pump.The steering pump gear turns under the impact frequently at automobile, when especially low speed is turned wearing and tearing larger, and in transmission work, occur rocking, and the steering pump gear often is subject to the corrosion of greasy dirt, thereby has influence on normal transmission work.
The model utility content
The purpose of this utility model provides a kind of steering pump gear, arc angling is set in teeth groove, and on the surface of the gear teeth wearing layer is set, strengthen the tightness that meshes between steering pump gear and other gears, simultaneously at wheel disc a plurality of vibration dampings hole is set, improve the stability of its transmission, to guarantee normal transmission work; In addition, has corrosion-resistant coating at the center bore inner wall of wheel disc, to improve the corrosion resistance of steering pump gear.
The technical solution of the utility model is as follows:
A kind of steering pump gear, include wheel disc, center on the surrounding of wheel disc along having a plurality of gear teeth respectively, it is characterized in that: the surface of described a plurality of gear teeth has wearing layer, 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 respectively equipped with a plurality of vibration dampings hole on through hole wheel disc on every side, has corrosion-resistant coating on the inwall of described through hole.
Described steering pump gear is characterized in that: described a plurality of vibration dampings hole be distributed in radially through hole around.
Described steering pump gear is characterized in that: a side of described through hole is provided with keyway.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, arc angling is set in teeth groove, and on the surface of the gear teeth wearing layer is set, strengthened the tightness that meshes between steering pump gear and other gears, simultaneously at wheel disc a plurality of vibration dampings hole is set, improve the stability of its transmission, thereby guaranteed normal transmission work; In addition, have corrosion-resistant coating at the center bore inner wall of wheel disc, improved the corrosion resistance of steering pump gear.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of steering pump gear includes wheel disc 1, edge, surrounding around wheel disc 1 has respectively a plurality of gear teeth 2, the surface of a plurality of gear teeth 2 has wearing layer 3, has teeth groove 4 between adjacent two gear teeth, and the both sides of teeth groove 4 bottom lands are respectively equipped with arc angling 5; The middle part of wheel disc 1 is provided with through hole 6, is respectively equipped with six vibration damping holes 7 on through hole 6 wheel disc 1 on every side, has corrosion-resistant coating 8 on the inwall of through hole 6.
In the utility model, six vibration damping holes 7 be distributed in radially through hole 6 around; One side of through hole 6 is provided with keyway 9, the assembling of convenience and live axle.
