Abstract
The utility model discloses a double-layer gear which comprises a plastic gear and a powder metallurgical gear. The center of the plastic gear is provided with a mounting hole, the thickness of the powder metallurgical gear is larger than that of the plastic gear, and the powder metallurgical gear is arranged in the mounting hole of the plastic gear in a pressure welding mode. According to the double-layer gear, the plastic gear and the powder metallurgical gear are respectively processed, then the powder metallurgic gear is pressed into the mounting hole of the plastic gear, and therefore the processing process is simplified and the disadvantage of insert molding is avoided.
Description
Technical field
The utility model relates to a kind of double-layer gear.
Background technique
By the double-layer gear that powder metallurgical gear and plastic gear combine, main at present through the processing of inserts Shooting Technique.Add man-hour, earlier the processing powder metallurgical gear is pressed into powder metallurgical gear in the mould of plastic gear then as inserts, at last injection moulding processing plastic gear again.In the existing technology during injection moulding mould must fit like a glove with powder metallurgical gear as inserts, otherwise just have the surface of plastic covered to powder metallurgical gear, processing technology is had relatively high expectations.
The model utility content
The utility model technical problem to be solved provides a kind of double-layer gear, and processing technology is simple, effectively avoids the drawback of inserts injection moulding.
In order to solve the problems of the technologies described above, the technological scheme that the utility model provided is: a kind of double-layer gear comprises plastic gear and powder metallurgical gear; The center of said plastic gear is provided with mounting hole; The thickness of said powder metallurgical gear is greater than the thickness of plastic gear, and powder metallurgical gear is crimped in the mounting hole of plastic gear.
The mounting hole of said plastic gear is a through hole.
After having adopted technique scheme; The utlity model has following beneficial effect: the utility model is processed worker's plastic gear and powder metallurgical gear respectively; Then powder metallurgical gear is pressed in the mounting hole of plastic gear, has simplified processing technology, avoided the drawback of inserts injection moulding.
Description of drawings
For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the axial sectional view of the utility model.
Label in the accompanying drawing is:
Embodiment
(embodiment 1)
See Fig. 1 and Fig. 2, the bilateral gear of present embodiment comprises plastic gear 1 and powder metallurgical gear 2.
The center of plastic gear 1 is provided with mounting hole.The thickness of powder metallurgical gear 2 is greater than the thickness of plastic gear 1, and powder metallurgical gear 2 is crimped in the mounting hole of plastic gear 1.The mounting hole of plastic gear 1 is a through hole.
Add man-hour, difference processing plastic gear 1 and powder metallurgical gear 2 are pressed into powder metallurgical gear 2 in the mounting hole of plastic gear 1 then earlier, have avoided the drawback of inserts injection moulding.
Above-described specific embodiment; Purpose, technological scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
