Problems solved by technology

However, due to the increasing requirements of modern automobiles for energy saving, environmental protection, comfort, and safety, the entire engine room has a complex and compact structure and a high temperature during operation. The rubber parts in it should have higher high temperature resistance and longer The maintenance period has higher and higher requirements on the durability of rubber parts.
The performance of chloroprene rubber has reached the limit, the phenomenon of early rubber aging and cracking is inevitable, which cannot meet the requirements of modern automobiles, and the increasingly stringent environmental protection requirements also limit the use of chloroprene rubber

Abstract

The invention discloses a triangle belt which includes a gum layer, an adhesive layer and a tooth gum layer. The gum layer, the adhesive layer and the tooth gum layer are adhesively fixed together in turn by mans of vulcanization and hot melting. The adhesive layer coats a line along its length direction. The tooth gum layer includes dentate parts. Components of the tooth gum layer and weight ratio of the components are: ethylene-propylene-diene monomer (EPDM): 100; aramid short fibre: 20-30; Zinc Oxide: 5-8; stearic acid: 1 - 2: vulcanizing agent: 2 - 5; curing agent DCP:2 - 4; reinforcing agent: 40- 60: softener: 10 - 15; ethylene content in EPDM: 30 - 70%, Mooney viscosity within the range of 55-65, rubber in the third monomer with in range of 0.5 - 4.5%. the triangular belt has the advantages of good high-and-low temperature performance, abrasive resistance and overall flexibility.

Description

technical field [0001] The invention relates to the technical field of transmission belts, in particular to a V-belt. Background technique [0002] Belt transmission is one of the most important forms of mechanical transmission. With the continuous improvement of industrial technology and the requirements for precision, light weight, functionalization and individualization of mechanical equipment, it is constantly moving towards high-precision, high-speed, high-power, high-efficiency, With the development of high reliability, long life, low noise, low vibration, low cost and compactness, its application range is getting wider and wider, and there are more and more transmission forms. As the main part of the belt transmission, the transmission belt has also changed from the original fragile to the functional part, replacing other transmission forms in many occasions. These transmission belts have been widely used in various fields such as automobiles, machinery, textiles, ho...
