Description

Main vee-pulley

Technical field

The utility model relates to auto parts and components field, particularly the main vee-pulley of one.

Background technique

In recent years, domestic labor cost constantly improves, machined part cost is more and more higher, power assistance pump for steering belt pulley but still adopts ironcasting belt pulley mostly, machining done by part, skiver's duration, processing cost is high, manufacturing efficiency is low, belt pulley toothed surfaces in machining process, find that there is pore and husky hole causes part rejection, in addition, cast iron belt pulley structure weight, take material, thus rotary inertia is large, balance quality is bad, Balance Treatment need be done, the slippage of vee belt and race is large, belt life is relatively short, the working life of bent axle can be reduced under the influence of centrifugal force in high-speed rotation, the vibrations of complete machine are also larger, even if there is minority producer to adopt spun type power assistance pump for steering belt pulley, but because spun type belt pulley is thinner, there is the situation of insufficient strength in use.

Summary of the invention

In order to solve the problem of prior art, the utility model embodiment provides one, and to have quality light, cheap, the main vee-pulley of the advantage that intensity is high.Described technological scheme is as follows:

The utility model embodiment provides a kind of main vee-pulley, and described main vee-pulley comprises belt pulley, be distributed on through hole on described belt pulley and mounting hole, the teeth groove be arranged on described belt pulley;

The pulley end body that described belt pulley comprises pulley body, extend to a lateral buckling from described pulley body, match with described pulley body the belt pulley matrix arranged;

Described mounting hole is provided with three, and the diameter of each described mounting hole is 7mm; Angle between every two described mounting holes is 120 °;

Described teeth groove comprise from described pulley end end of body extend to side first raised, with described first raised be connected the first type groove, from described first type groove to opposite side bend extend second raised, from described second raised to opposite side bend extend the 3rd raised, from described 3rd raised to a lateral buckling extend the 4th raised, raisedly bend to opposite side extend the 5th raised from the described 4th; Fillet radius between described first type groove and described second projection is 0.2mm; Angle between described 4th projection and described 5th projection is 34 °; Fillet radius between described 4th projection and described 5th projection is 3.5mm.

The beneficial effect that the technological scheme that the utility model embodiment provides is brought is:

Preparation process is simple, surface production flow harden, and tissue density improves, and the intensity hardness of wheel rooved face is improved, and dimensional accuracy is high, the slippage of vee belt and race is little, and belt life is long, and aesthetic in appearance; In use, because weight is lighter than cast iron belt pulley, in high-speed rotation, greatly reduce centrifugal force, improve bearing, the working life of bent axle, reduce the vibrations of complete machine; There is quality light, cheap, the advantage that intensity is high, not only ensured that the quality of product also assures that the intensity of product, not only reduced complete vehicle weight, one of automobile lightweight approach, and can reduce costs, improve car load and competition of the same trade.

Accompanying drawing explanation

In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is the structural representation of the main vee-pulley that the utility model embodiment provides;

Fig. 2 is the side view of the main vee-pulley that the utility model embodiment provides;

Fig. 3 is the partial view of the main vee-pulley that the utility model embodiment provides.

Embodiment

For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.

Embodiment

The utility model embodiment provides a kind of main vee-pulley, and see Fig. 1, Fig. 2, described main vee-pulley comprises belt pulley 1, be distributed on through hole 2 on belt pulley 1 and mounting hole 3, the teeth groove 4 be arranged on belt pulley 1;

The pulley end body 12 that belt pulley 1 comprises pulley body 11, extend to a lateral buckling from pulley body 11, match with pulley body 11 the belt pulley matrix 13 arranged;

Mounting hole 3 is provided with three, and the diameter of each mounting hole 3 is 7mm; Angle between every two mounting holes 3 is 120 °;

See Fig. 3, teeth groove 4 comprise extend to side from pulley end body 12 end first raised 41, with the first type groove 42 that first raised 41 is connected, from the first type groove 42 to opposite side bend extend second raised 43, from second raised 43 to opposite side bend extend the 3rd raised 44, from the 3rd raised 44 to one lateral bucklings extend the 4th raised 45, bend the extend the 5th raised 46 from the 4th raised 45 to opposite side; Fillet radius between first type groove 42 and the second projection 43 is 0.2mm; Angle between 4th projection 45 and the 5th projection 46 is 34 °; Fillet radius between 4th projection 45 and the 5th projection 46 is 3.5mm.

The beneficial effect that the technological scheme that the utility model embodiment provides is brought is:

Preparation process is simple, surface production flow harden, and tissue density improves, and the intensity hardness of wheel rooved face is improved, and dimensional accuracy is high, the slippage of vee belt and race is little, and belt life is long, and aesthetic in appearance; In use, because weight is lighter than cast iron belt pulley, in high-speed rotation, greatly reduce centrifugal force, improve bearing, the working life of bent axle, reduce the vibrations of complete machine; There is quality light, cheap, the advantage that intensity is high, not only ensured that the quality of product also assures that the intensity of product, not only reduced complete vehicle weight, one of automobile lightweight approach, and can reduce costs, improve car load and competition of the same trade.
