Abstract
The utility model relates to a double metal worm wheel, composed of a copper wheel rim and a black metal wheel core. The copper wheel rim is made of the copper base alloy and is formed by the centrifugal casting mode, and the internal surface of the copper wheel rim is provided with a ring table and a plurality of concave arc-shaped mortises. The wheel core in the internal circle of the copper wheel rim is made of the black metal and is formed by the casting mode. The surface of copper wheel rim is processed and forms a turbine-tooth shape, and the center of the wheel core is provided with internal holes. Certainly, the black metal wheel core can be also provided with the ring table and a plurality of concave arc-shaped mortises, and each mortise can be made and forms a polygon shape.
Description
This model utility is used in the bigger copper gear of machine building industry, is specially adapted to make the worm gear of worm gear pairs.
Making the bimetal worm gear at present has: (1) rim formula, and copper wheel edge and ferrous metal core wheel interference fit, processing and assembling is loaded down with trivial details, and manufacturing efficiency is low.(2) bolt jointing type require the bolt hole of copper wheel edge and ferrous metal core wheel to twist system simultaneously, and amount of finish is big, consumptive material consuming time.(3) insert type casts out the ferrous metal core wheel earlier, casts out the copper wheel edge at the common casting method of its external application again, but the copper tissue easily produces defective.(4) while spun casting copper wheel rim and ferrous metal core wheel, the core wheel profile is restricted, technology is complicated, wayward.
The purpose of this utility model is: be to save copper, and obtain and organize fine and closely woven copper wheel edge and a kind of desirable, simple bimetal worm gear of technology is provided.
The technological scheme of this model utility: be to produce copper wheel edge (1) with spun casting with copper base alloy earlier, process ring platform (2) and several concave arc shape tongue-and-grooves (3) at internal circular surfaces, circle is with ferrous metal casting black metal core wheel (4) in the copper wheel edge, again profile of tooth on machining worm wheel surface (5) and ferrous metal core wheel endoporus (6) by drawing.Also can process the ferrous metal core wheel (4) of band tongue-and-groove (2) and several arc bumps (3) earlier, and then spun casting copper wheel edge, otherwise, also the edge of ferrous metal core wheel (4) can be processed into ring platform and concave arc shape tongue-and-groove.Spun casting copper wheel edge (1) again, more than said concave arc shape tongue-and-groove (3) can be processed into polygonal.Also can be on the centrifugal casting machine earlier behind the casting copper wheel edge (1), casting black metal core wheel (4) again during to proper temperature.
The concrete structure of this model utility is described below in conjunction with the accompanying drawings: go out Huan Tai (2) and several concave arc shape tongue-and-grooves (3) with copper base alloy centrifugal casting copper wheel rim (1) internal circular surfaces roughing, in the copper wheel edge in the circle with ferrous metal casting black metal core wheel (4), and then the endoporus (6) of the profile of tooth on machining worm wheel surface (5) and ferrous metal core wheel (4) by drawing.
Description of drawings:
Accompanying drawing: novel dual metal worm gear arrangement schematic representation:
1, copper wheel edge; 2, Huan Tai; 3, concave arc shape tongue-and-groove; 4, core wheel;
5, profile of tooth; 6, core wheel endoporus
This practical having the following advantages: 1, technology is simple, combination is firm; 2, save copper material; 3, copper fine and closely woven, mechanicalness Can be good; 4, production efficiency height
Claims (3)
1, a kind of novel dual metal worm gear is made up of copper wheel edge and ferrous metal core wheel.It is characterized in that: copper wheel edge (1) is that the copper base alloy spun casting forms, internal circular surfaces makes ring platform (2) and several concave arc shape tongue-and-grooves (3), core wheel (4) in the copper wheel edge in the circle is cast into ferrous metal, in copper wheel edge surface Machining worm gear profile of tooth (5), at core wheel (4) center processing endoporus (6).
2, according to the said bimetal worm gear of claim 1, it is characterized in that: ferrous metal core wheel (4), can band platform (2) and several concave arc shape tongue-and-grooves (3).
3, according to the said bimetal worm gear of claim 1, it is characterized in that: several concave arc shape tongue-and-grooves (3) can be made polygonal.
