Belt pulley and manufacturing method thereof

Abstract

The invention relates to the technical field of mechanical parts machining, in particular to a belt pulley and a manufacturing method thereof. At present, the belt pulley is mainly made by adopting acasting method, the cost is high, the production efficiency is low, pollution to the environment is serious in the casting process, the product weight is high, fast starting and stopping are difficultto realize, and heat generated during working is not easy to dissipate. According to the technical scheme, the pressing and welding processes are adopted to make the belt pulley, a metal sheet is made into a belt groove ring body with grooves, a wheel rim ring body and a wheel spoke plate body, then the belt groove ring body, the wheel rim ring body, the wheel spoke plate body and a shaft sleeveare welded to form a wheel body, and in the process of machining of the wheel rim ring body, a plurality of through holes are punched in a rim surface for heat dissipation of the bottom of a belt groove. According to the belt pulley and the manufacturing method thereof, various metal materials can be selected for making the belt pulley, the machining difficulty and the cost are reduced, the production efficiency is greatly improved, environmental pollution is reduced, the weight of a wheel body is reduced, the heat dissipation ability is enhanced, and the situation that the equipment is drivento start and stop quickly is realized.

Description

technical field [0001] The invention relates to the technical field of mechanical parts processing, in particular to a pulley and a manufacturing method thereof. Background technique [0002] The pulley is a disc-hub mechanical part that transmits power. Due to its special structure, the manufacturing process is usually based on casting. The casting method is used to make the pulley, the cost of raw materials is high, the amount of consumption is large, the casting process is time-consuming, the production efficiency is low, the processing cost is high, and it is harmful to the operator's body, especially the environment and air pollution are serious during the casting process; while in use During the process, the finished product of this type of product weighs a lot, and its large inertia increases the starting energy consumption of the pulley, making it difficult to achieve fast start and stop. In addition, another defect of the casting pulley is that the friction between...
