Problems solved by technology

With the increase of transmission power, it is necessary to use several V-belts at the same time to meet the requirements. Due to errors in width and thickness of a single V-belt, there is always an error in the length of the V-belt, so it is easy to cause stress when using it. Uneven, that is, the transmission power is uneven, easy to jump, turn over, and eventually cause several V-belts to be scrapped at the same time, that is, one of them is damaged first and all V-belts have to be replaced, resulting in waste of resources

Embodiment Construction

[0024] like figure 1 As shown, a group trimmed V-belt is composed of more than two V-belts connected side by side to form an integrated structure, and a skeleton is arranged inside the V-belt. The lower part of the V-belt is a tooth-shaped part, and the upper part is a flat bottom. The adjacent V-belts are connected to form an integrated structure through the flat bottom. The skeleton is set at the transition between the tooth-shaped part and the flat bottom. The V-belt is a neoprene V-belt; the skeleton is a polyester hard cord.

[0025] Combined trimming V-belt adopts the following manufacturing method, such as image 3 Process shown:

[0026] a. Ingredients: weigh the raw materials according to the formula;

[0027] b. Mixing: Mix the weighed raw materials in the internal mixer according to the process to make a mixed rubber;

[0028] c. Tablet pressing: Press the mixed rubber into various thicknesses according to the requirements on the open mill, control the temperatu...

Abstract

The combined edge-cutting V-belt is one combined structure of two or more parallel V-belts, and has lower toothed part, upper flat part, inside skeleton in the transition part between the toothed part and the upper flat part, and flat part connection between adjacent V-belts. The V-belt is made of chloroprene rubber and the skeleton is hard polyester string. The technological process includes the steps of compounding material, mixing, pressing sheet, splicing, forming, sulfurizing, cooling and demolding, cutting, grinding, etc. The combined edge-cutting V-belt has simple structure, easy installation, balanced stress, homogeneous transmission, smooth operation and convenient replacement, simple production process and low production cost.

Description

technical field [0001] The invention relates to a V-belt with side trimmed in combination and a manufacturing method thereof. Background technique [0002] Edge-cut V-belts are mainly used in transmission equipment. With the increase of transmission power and the development of the automobile industry, tapes with fast speed, high transmission power, high temperature resistance, oil resistance, and acid and alkali resistance are required. Edge-cut V-belts have replaced triangle belts. belts are widely used. Trimmed V-belts are made of neoprene and polyester hard cords, and the operating temperature is about 85-100°C. It can be made into any width, thickness, length and angle according to the needs. At present, cars, trucks, buses and most of the equipment at home and abroad mostly use edge-cut V-belts and speed-adjusting belts. With the increase of transmission power, it is necessary to use several V-belts at the same time to meet the requirements. Due to errors in width an...
