Stepless speed change belt glue sleeve and manufacturing method thereof

Abstract

The invention provides a stepless speed change belt glue sleeve and a manufacturing method thereof. The stepless speed change belt glue sleeve comprises a back layer, a bottom glue layer, an adhesivelayer located between the back layer and the bottom glue layer and a thread rope located in the adhesive layer, wherein the back layer is of a sewn cylindrical structure, and comprises a top adhesivelayer, an inner glue layer, a top fabric layer located between the top adhesive layer and the inner glue layer and a label layer located on the outer side surface of the top adhesive layer. Accordingto the stepless speed change belt glue sleeve, an outer adhesive layer is attached to the outer side surface of the top fabric layer, so that the label layer conveniently adheres to the outer adhesivelayer, the winding process in the stepless speed change belt production is easily sequenced, the winding process time is shortened, the factory production takt is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a continuously variable transmission belt rubber sleeve and a manufacturing method thereof, in particular to an unvulcanized continuously variable transmission belt rubber sleeve and a manufacturing method thereof. Background technique [0002] CVT belts are widely used in motorcycles, multi-purpose vehicles, ATVs, sleds, etc. CVT belts generally include: top fabric, adhesive layer, adhesive layer, cords in the adhesive layer, and primer Layer and bottom fabric, the top fabric also has a transferred label containing information such as date and trademark. After vulcanizing the label layer containing information, the label transfers the information on the label layer to the outer surface of the rubber sleeve, and then removes the information obtained from the label layer, such as figure 1 . Since the label layer has no adhesion, it needs to be wound layer by layer, resulting in a long production time for the continuously varia...

AI Technical Summary

Problems solved by technology

However, the use of this kind of label makes it take a long time to make rubber sleeves, and it has become a bottleneck station in the production of continuously variable transmission belts, which seriously affects the production cycle of continuously variable transmission belts. For the factory, the longer the production cycle, it means The fewer the number of CVT belts produced in each shift, the higher the cost of the factory and the lower the market competitiveness, so it is urgent to provide a new CVT rubber sleeve or a new CVT rubber A set of production methods to improve this situation, shorten the factory production cycle, and improve the competitiveness of products
