Problems solved by technology

The products produced by this process not only have a rough welding surface and are of low grade, but also produce a large shrinkage internal stress around the weld after welding, which is difficult to eliminate. Therefore, deformation and welding heat-affected zone fractures are prone to occur during use, which affects the stability of performance. , at the same time, the product affects the balance performance of the pulley due to the unevenness of the welding filler

Embodiment Construction

[0015] Such as figure 1 As shown, as an embodiment of the present invention is a single-stage coaxial multi-ribbed pulley, including a wheel rim 24, a wheel spoke 25 and a wheel hub 26, and a plurality of multi-ribbed V-shaped grooves 24.1 are opened on the wheel rim 24, The effective diameter center of each V-shaped groove 24.1 is concentric with the shaft hole 27 center of the wheel hub 26, and each V-shaped groove 24.1 is left-right symmetrical, and its center line is perpendicular to the central axis of the wheel hub 26. The wheel rim 24, the spoke 25 and the wheel hub 26 There is an annular groove 28 between the three, and there are several arc grooves 29 on the spoke 25. The rim 24, the spoke 25 and the hub 26 are integrally formed by cold spinning of steel plates on a spinning machine. In this embodiment, the groove pitch of the V-shaped groove 1.1 is 3.65±0.05mm, and the groove angle is 40°±0.5°.

Abstract

The invention relates to a cold spinning one-step coaxial multi-wedge type belt pulley which comprises a rim, a spoke and a hub, wherein the rim is provided with a plurality of multi-wedge type V-shaped grooves, effective diameter center of each V-shaped groove is concentric with axle hole center of the hub, each V-shaped groove is in bilateral symmetry, and the centre line of each V-shaped groove is vertical to the centre axle line of the hub, annular grooves are arranged among the rim, the spoke and the hub, the spoke is provided with a plurality of arc grooves, and the rim, the spoke and the hub are integrally formed on a spinning machine by using a steel plate in a cold spinning way. The cold spinning one-step coaxial multi-wedge type belt pulley has good softness of a flat belt pulley and large drive power of a V-shaped belt pulley, can absorb impaction and vibration, and is quieter than that of chain and gear drive with little noise. The invention also provides a fabricating method and fabricating equipment of the product.

Description

technical field [0001] The invention relates to a cold spinning belt pulley, in particular to a single-stage coaxial multi-ribbed belt pulley and its processing method and processing equipment. Background technique [0002] The pulley is the most common transmission part in mechanical transmission. It is generally composed of three parts: the rim, the web and the hub. There are transmission forms such as flat belt transmission and V-belt transmission. The flat belt drive pulley has the advantages of slipping when overloaded, safety protection, and good flexibility. When the transmission ratio is not accurate, the precision is not high, and the use time is long, the flat belt will elongate by itself when the weather is hot, and it will also slip and generate power. loss. The V-belt transmission pulley is equipped with multiple flat belt grooves, which has the advantage of large transmission power, but because each belt is separate and not conjoined, the expansion and contrac...
