Abstract

The invention discloses a bottom rubber interlining type joined V-belt, which aims to overcome the defects that an existing joined V-belt is narrow in use temperature range and short in service life when the use temperature range is exceeded. The bottom rubber interlining type joined V-belt comprises a top fabric layer, a stretching layer, an adhering layer and a compressing layer sequentially from outside to inside, the middle of the flat inner surface of the compressing layer is provided with a V-shaped groove, framework layers are distributed in the adhering layer, the compressing layer consists of an outer main rubber layer and an inner bottom rubber interlining layer, the main rubber layer is connected with the adhering layer, the bottom rubber interlining layer consists of rubber fabric layers and a bottom rubber layer, the rubber fabric layers are spaced by the bottom rubber layer, the stretching layer, the adhering layer and the compressing layer are mainly made of ethylene-propylene-diene-terpolymer rubber, and the top fabric layer and rubber fabrics of the rubber fabric layers in the bottom rubber interlining layer are subjected to dipping treatment of rubber solution of the ethylene-propylene-diene-terpolymer rubber. The bottom rubber interlining type joined V-belt can be normally and effectively operated for a long time within the wider temperature range from -40 DEG C to 121 DEG C.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a grouped bottom rubber clip cloth type V-belt for transmitting mechanical power. Background technique [0002] Combined bottom rubber sandwich cloth V-belts are generally used in high-power mechanical equipment. With the widespread use of mechanical equipment, the conditions of use are becoming increasingly harsh. For example, the winter temperature in the North and South Poles and Russia is below -40°C. At present, most of the combined V-belt materials are natural rubber or neoprene. The effective use temperature range of natural rubber is -20°C to 80°C, and the effective use temperature range of neoprene is -30°C to 100°C. In the temperature range, the service life of the combined bottom rubber and cloth V-belt will be greatly reduced. At the operating temperature of -40°C, these two types of belts have lost their elasticity, and the service life is only about 10 hours. ...
