Abstract

The invention discloses a rubber material for preparing winding couplers and a forming method for winding couplers. The rubber material for preparing the winding couplers is prepared from the following raw materials: natural rubber, R300 special white carbon black, an anti-ageing agent and the like; and the forming method for the winding couplers comprises the following steps of: immersing rayon threads in chlorine glue size, drying and coiling into coils; pulling the coils into rectangular coils, and sleeving on a standby framework; fixing, and putting into a mold of vulcanizing equipment; performing mixing and open milling on the rubber material for preparing the winding couplers, and immersing in an RS620 parting agent; taking out, performing air drying and cooling; and injecting into a cavity of the mold by using an injection machine, vulcanizing for 720 to 840 seconds, cooling, and trimming to obtain the winding couplers.

Description

1. Technical field [0001] The invention relates to a rubber material for preparing a wire-wound coupling and a forming method of the wire-wound coupling. 2. Background technology [0002] As an important part of the connection between the gearbox and the transmission shaft of the car, the winding coupling plays a role in shock absorption and buffering during the running of the car (some high-end SUVs abroad are currently using this technology), making the car more comfortable during driving. Smooth, increasing ride comfort. The structure and shape of the wire-wound coupling is complex, and there are a lot of nylon wires inside. At the same time, the process of winding, pulling, and dipping is complicated, and the entire manufacturing technology is very high. At the same time, due to the strict performance requirements of the wire wound coupling, there are tests such as high and low temperature durability, torsional stiffness, axial stiffness, deflection, etc., and the chara...
