Abstract
The utility model discloses a sun wheel which comprises a sun wheel body. A through hole is formed in the middle of the sun wheel body, the central axis of the sun wheel body and the central axis of the through hole are overlapped, the surface of the sun wheel body is coated by a layer of wear-resistant materials, and the radius of the through hole is 4-6cm. The sun wheel is formed by one-time casting, therefore, the through hole structure of the sun wheel is made to be capable of saving a large quantity of raw materials under the premise that existing performance is ensured, machining procedures are also reduced, mass production is convenient, and the service life of the sun wheel is made to be prolonged greatly through the wear-resistant materials.
Description
Technical field
The utility model discloses a kind of geared parts, be specifically related to a kind of sun gear.
Background technique
Sun gear is the vitals in the Planetary Gear Transmission, and the processing request of casting with holes is higher, and processing cost is also higher, and the wear resistance of gear has also been proposed higher requirement.
The model utility content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of sun gear.
Technological scheme: for solving the problems of the technologies described above, the utility model provides a kind of sun gear, comprise the sun gear body, be through hole in the middle of the described sun gear body, the central axis of described sun gear body and the central axes of through hole, the top layer of described sun gear body scribbles one deck high-abrasive material, and the radius of described through hole is 4 ~ 6cm.
Further, described high-abrasive material is enamel material.
Further, the cross section radius of an end of described sun gear body is less than the cross section radius of sun gear body remaining part.
Beneficial effect: the utility model in terms of existing technologies, the utility model has been saved a large amount of raw material by to the improvement of sun gear body structure, has guaranteed simultaneously itself and wear resistance, has prolonged the working life of sun gear.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1: the sun gear body; 2: through hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of sun gear comprises the sun gear body, be through hole 2 in the middle of the described sun gear body 1, the central axes of the central axis of described sun gear body 1 and through hole 2, the top layer of described sun gear body 1 scribbles one deck high-abrasive material, and the radius of described through hole 2 is 4 ~ 6cm; Described high-abrasive material is enamel material; The cross section radius of one end of described sun gear body 1 is less than the cross section radius of sun gear body 1 remaining part.
The utility model has been saved a large amount of raw material by to the improvement of sun gear body structure, has guaranteed simultaneously itself and wear resistance, has prolonged the working life of sun gear.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
