In China's vast manufacturing group, synchronous belt is widely used. In order to make our machine used in synchronous belt for a longer time, effectively reduce the production cost. All kinds of enterprises need to choose the high quality of the synchronous belt. It usually has three characteristics. 1, excellent wear resistance, when the pulley are usually made of steel, aluminum alloy, cast iron, brass and other materials, the pulley due to the high intensity of ontology and the belt body friction test is wear-resisting level. When we select a product, we should highly match with pulleys. Due to the stability of the polyurethane, polyurethane synchronous belt has good abrasion resistance, can be use for a long time, not easy to wear and tear. 2, good oil resistance, in use process, synchronous belt wheel may contact with other materials and equipment used in the lubricating oil. As a result, the product itself needs to have good oil resistance, so you can use for a long time in the practical application, because it's not easy to corrosion of oil. 3, good strength: because of the synchronous belt wheel in use process need long time to maintain its complete structure, so it can continue to work normally. In terms of maintain its complete structure, the strength of the product itself needs to have good, so that it is not easy to external damage, so as to realize long-term application. In addition, when choosing timing belt, we should first consider the mechanical adaptability. High matching precision belt can effectively assist production, greatly reduce the cost.
