Abstract
The utility model discloses a multi-slot folding spinning pulley for a crank shaft, which is formed by board-making spinning technology. The multi-slot folding spinning pulley comprises a rim and a shaft sleeve. The rim and the shaft sleeve are welded; a plurality of V-shaped slots are formed on the outer surface of the rim at regulated intervals; and the inner wall on one side of the rim is tightly adhered to the side walls of the adjacent V-shaped slots. The multi-slot folding spinning pulley has the advantages that the production efficiency is high, and the balance quality is good; as no metal flow exists during the forming process, the manufacture process is simple, the service life of the crank shaft is increased, and the vibration of the complete machine is reduced.
Description
Technical field
The utility model relates to component of machine, particularly a kind of multiple-grooved folding and spinning belt pulley that is used on the bent axle.
Background technique
Cast iron belt pulley structure in the market weighs, takes material, thereby rotary inertia is big, balance quality is bad, need do Balance Treatment, the slippage of vee belt and race is big, belt life is shorter relatively, can reduce the working life of bent axle in the high speed rotating process under action of centrifugal force, and the vibrations of complete machine are also bigger.
Rotary pressure technology also is the metal spinning forming technique, by rotation make it force bearing point by put line by line to face, simultaneously give certain pressure and make metallic material along this direction distortion with flow and the technology of a certain shape of moulding in certain direction.Common spinning belt pulley is had relatively high expectations to plastic deformation of metal material ability and mobile performance, complex process, and also rotary inertia is big, and balance quality does not reach usage requirement, has wasted energy consumption.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of multiple-grooved folding and spinning belt pulley that is used on the bent axle.
The multiple-grooved folding and spinning belt pulley that is used on the bent axle provided by the utility model adopts the moulding of plate system spinning process, comprise wheel rim, axle sleeve, described wheel rim adopts welding manner to be connected with axle sleeve, described wheel rim outer surface spacing in accordance with regulations forms multiple tracks " V " type groove, in addition, the inwall of described wheel rim one side is close on the sidewall of adjacent " V " type groove.
Owing to adopted above technological scheme, the utility model manufacturing efficiency height, balance quality is good, because metal flow does not take place in forming process, so preparation process is simple, the surface production flow harden, tissue density improves, and the intensity hardness of wheel rooved face is improved, and dimensional accuracy height, the slippage of vee belt and race is little, and belt life is long, and aesthetic in appearance.In use.Because of weight is lighter than cast iron belt pulley, in the high speed rotating process, greatly reduce centrifugal force, improved bearing, in the working life of bent axle, reduced the vibrations of complete machine.
Description of drawings
Fig. 1 is a sectional drawing of the present utility model.
In the drawings: 1-wheel rim, 2-axle sleeve, 3-" V " type groove
Embodiment
As shown in Figure 1, a kind of multiple-grooved folding and spinning belt pulley that is used on the bent axle that the utility model provides, this multiple-grooved folding and spinning belt pulley adopts the moulding of plate system spinning process, the surface is carried out flow harden and is handled, the described multiple-grooved folding and spinning belt pulley that is used on the bent axle comprises wheel rim 1, axle sleeve 2, described axle sleeve 2 is a cylindrical structure, described wheel rim 1 is the disc type structure, the moulding of the plate system of utilization spinning process, and described wheel rim 1 and axle sleeve 2 adopt welding manners to be connected, and forms through fine finishing again, described wheel rim 1 outer surface spacing in accordance with regulations forms multiple tracks " V " type groove 3, in addition, the inwall of described wheel rim 1 one sides is close on the sidewall of adjacent " V " type groove, realizes folding.
Claims (2)
1. multiple-grooved folding and spinning belt pulley that is used on the bent axle, comprise wheel rim (1), axle sleeve (2), it is characterized in that: described axle sleeve (2) is a cylindrical structure, described wheel rim (1) is the disc type structure, described wheel rim (1) outer surface spacing in accordance with regulations forms multiple tracks " V " type groove (3), in addition, the inwall of described wheel rim (1) one side is close on the sidewall of adjacent " V " type groove.
