Rust-proof belt pulley and preparation method thereof

Abstract

The rust-proof belt pulley comprises a steel wheel, belt grooves are formed in the left side and the right side of the surface of the steel wheel, tungsten carbide is arranged in an inner cavity of the steel wheel, threaded holes are formed in the left side and the right side of the surface of the steel wheel, and the surface of the steel wheel is sprayed with water-based rust-proof paint. A user polishes the surface of the steel wheel, then a tapping machine is used for drilling a threaded hole in the surface of the steel wheel, then the steel wheel is slotted on a machine tool so that a belt groove can be formed in the surface of the steel wheel, after the belt groove is formed, the steel wheel is subjected to acid pickling and ultrasonic cleaning, and the steel wheel is obtained. The steel wheel is subjected to high-temperature baking in the furnace body through the steps, tungsten carbide is added at the preset temperature, the problems that an existing belt wheel needs to bear the transmission function and is prone to oxidation and rusting when exposed in air are solved, work abrasion of the belt wheel is reduced, and the service life of the belt wheel is prolonged.

Description

technical field [0001] The invention relates to the technical field of pulleys, in particular to a rust-proof pulley and a preparation method. Background technique [0002] Pulleys, belonging to the hub type parts, are generally relatively large in size. The manufacturing process is generally based on casting and forging. Pulleys are needed in large machinery, but the existing pulleys have to carry the transmission function and are easily exposed to the air. Oxidation and rust appear, which increases the wear and tear of the pulley and reduces the service life of the pulley. SUMMARY OF THE INVENTION [0003] In order to solve the problems raised in the above background technology, the purpose of the present invention is to provide a rust-proof pulley and a preparation method, which have the advantages of good rust-proof effect, and solve the problem that the existing pulley needs to carry a transmission function and is exposed to the air. Oxidation and rust problems are p...
