Abstract
The invention discloses a manufacture method of a light load gear structure. A metal panel veneer with a proper mark is chosen to serve as the blank material of a gear ring; and the proper stamping process is adopted to manufacture the gear ring with a cold stamping method. In order to ensure that the gear ring and a hub can be reliably combined and fixed, the inner circle surface of the gear ring is manufactured into a proper convex-concave shape; the hub is made of engineering plastics; according to the process characteristics and technical requirement situations, the engineering plastics can be polyamide PC, polyamide PA, polyformaldehyde POM and the like. The powdery raw material of the engineering plastics and a prefabricated gear ring are put in a corresponding die and are pressed into the hub by a proper craft; and meanwhile, the gear ring and the hub are fixed and combined.
Description
Technical field
The present invention relates to a kind of manufacturing of light-load gear structure, particularly a kind of manufacture method of light-load gear structure belongs to machine components and mechanical transmissioning technology field.
Background technology
Gear is the common part in the machine driving, at present, gear generally adopts the method manufacturing of metal cutting to form, gear for some underloadings also has the cold-stamped of employing manufacture method, the gear that no matter adopts the method for metal cutting or punching press to manufacture, these gears all are the version of bulk metal, the gear of this structure, though have the bigger advantage of bearing load,, for some underloadings transmission mechanism in, for example: in signal transmission in electromechanical integration technology and the transmission mechanism that transmits, the gear of this bulk metal structure then exists the raw material metal waste more serious, the defective that cost is higher.
Summary of the invention
The objective of the invention is to: the manufacture method that a kind of light-load gear structure is provided, adapt to the use needs in some underloading transmission mechanisms, thereby reach the requirement that both can reach drive technology, have simultaneously have easy to manufacture, save metal material, lower-cost purpose.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of manufacture method of light-load gear structure, it is made up of gear ring and wheel hub, it is characterized in that: select the blank material of suitable trade mark metal blank for use as gear ring, select suitable Sheet Metal Forming Technology for use, make gear ring by the cold-stamped method, in order to guarantee that gear ring and wheel hub have reliable the combination with fixing, the inner headed face of gear ring should produce the convex-concave of suitable shape; The employed material of described wheel hub is engineering plastics, according to process characteristic and specification requirement situation, engineering plastics can adopt polyamide PC, polyamide PA, polyformaldehyde POM etc., the raw material and the ready-made gear ring of engineering plastic powder shape is placed in the corresponding mould, be pressed into wheel hub through suitable technology, simultaneously, together with gear ring and wheel hub secure bond.
Beneficial effect: among the present invention, owing to have only work gear ring partly, adopt the way manufacturing of metal sheet stamping moulding, and wheel hub adopts the engineering plastics compression molding, and with wheel hub and the fixing method of gear ring, so, both can reach the requirement of drive technology, have again simultaneously easy to manufacture, save metal material, lower-cost purpose, can adapt to and general underloading drive technology field.
Description of drawings
Below in conjunction with accompanying drawing structure of the present invention is described further.
Accompanying drawing is a structure principle chart of the present invention.
Shown in the figure: 1, gear ring; 2, wheel hub.
The specific embodiment
Select the blank material of suitable trade mark metal blank for use as gear ring (1), select suitable Sheet Metal Forming Technology for use, make gear ring (1) by the cold-stamped method, in order to guarantee gear ring and wheel hub reliable the combination with fixing arranged, the inner headed face of gear ring should produce the convex-concave of suitable shape; The employed material of described wheel hub is engineering plastics, according to process characteristic and specification requirement situation, engineering plastics can adopt polyamide PC, polyamide PA, polyformaldehyde POM etc., the raw material and the ready-made gear ring (1) of engineering plastic powder shape is placed in the corresponding mould, be pressed into wheel hub (2) through suitable technology, simultaneously, together with gear ring (1) and wheel hub (2) secure bond.
Claims (1)
1. the manufacture method of a light-load gear structure, it is characterized in that: select the blank material of suitable trade mark metal blank for use as gear ring (1), select suitable Sheet Metal Forming Technology for use, make gear ring (1) by the cold-stamped method, in order to guarantee that gear ring and wheel hub have reliable the combination with fixing, the inner headed face of gear ring should produce the convex-concave of suitable shape; The employed material of described wheel hub is engineering plastics, according to process characteristic and specification requirement situation, engineering plastics can adopt polyamide PC, polyamide PA, polyformaldehyde POM etc., the raw material and the ready-made gear ring (1) of engineering plastic powder shape is placed in the corresponding mould, be pressed into wheel hub (2) through suitable technology, simultaneously, together with gear ring (1) and wheel hub (2) secure bond.
