V belt wheel for skid resistance by centrifugal force

Abstract

The invention provides a V belt wheel for skid resistance by centrifugal force. The V belt wheel comprises a wheel flange, a wheel arm, a wheel hub, a V belt groove, an anti-skid cavity, an anti-skidblock, a connecting rod, a connecting rod piston, a movable cavity, a first overflow valve, a hydraulic cylinder, a hydraulic cylinder piston, an air hole and a second overflow valve. The V belt groove is formed in the periphery of the wheel flange, the anti-skid cavity is formed in the bottom of the V belt groove, the anti-skid block is arranged in the anti-skid cavity, the connecting rod is fixedly connected at the bottom of the anti-skid block, the connecting rod piston is fixedly arranged at the other end of the connecting rod, the first overflow valve and the second overflow valve are arranged at the bottom of the movable cavity, the hydraulic cylinder piston is slidably arranged on the inner wall of the hydraulic cylinder, and an air hole is formed in the bottom of the hydraulic cylinder. According to the anti-skid V belt wheel, the anti-skid block, the connecting rod and the connecting rod piston are matched, the anti-skid block can be fitted with the bottom of a V belt by the aid of the outward swung centrifugal force when the V belt wheel rotates at high speed, frictional force between the V belt and the V belt wheel is improved, transmission stability of the V belt is improved, and sliding probability is reduced.

Description

technical field [0001] The invention relates to the technical field of V-belt pulleys, and more specifically relates to a V-belt pulley that utilizes centrifugal force to prevent slipping. Background technique [0002] V-belt transmission is widely used in various occasions, but after a long-term use of the V-belt, the V-belt will be stretched and lengthened, and the diameter of the V-belt will become smaller, resulting in a smaller friction between the V-belt and the V-belt pulley, resulting in Slip phenomenon, and in the case of high-speed rotation, the V-belt is affected by high-speed rotation, and the centrifugal force will be very large, thereby reducing the contact area between the V-belt and the V-belt pulley, resulting in insufficient friction between them, which will also Slippage occurs, affecting the transmission. [0003] Based on above-mentioned inventor's discovery, existing V-belt pulley mainly has the following deficiencies, such as: [0004] When the V-bel...
