Abstract

The invention discloses an isolator belt pulley. The isolator belt pulley comprises a belt pulley main shaft, a sleeve, a belt pulley outer ring, a spring type seal ring and a profile roller one-way retainer, wherein two ends of the profile roller one-way retainer are respectively provided with a sealed carrying bearing and a carrying bearing. The belt pulley is characterized in that: a group of profile rollers are uniformly embedded in the profile roller one-way retainer through springs. According to the isolator belt pulley, hard friction of a traditional gear type thrust plate is canceled, the profile roller one-way retainer is adopted, and the profile rollers and the belt pulley main shaft form flexible friction to achieve the aim of one way by utilizing the change of contact angles between cambered surfaces of internal surfaces of the profile rollers and the belt pulley main shaft when relative rotating speed between the belt pulley outer ring and the belt pulley main shaft changes, so that the hard friction inside the belt pulley is completely avoided, noise is reduced, and the service life is prolonged; and he sealed carrying bearing and the spring type seal ring are adopted, so that dust is prevented from entering, and the failure rate is reduced.

Description

technical field [0001] The invention relates to a one-way pulley. Background technique [0002] The engine generator one-way pulley can avoid the reverse current generated during reverse rotation to prevent damage to electronic devices in the car, improve the life of the generator system, and reduce carbon monoxide emissions. Most of the pulleys of the motor-generator one-way devices on the market are driven by rolling bearings. The radial dimension of the rolling bearing is large, the vibration damping ability is poor, the service life is low when running at high speed, and the sound is loud. And rolling bearings have high requirements for bearings. Generally, after the bearings are installed in the working position, they are often poorly installed and positioned due to manufacturing. Therefore, due to fatigue and thermal expansion of the shaft, the routine bearings bear excessive loads, causing early damage. Therefore, the bearing has many disadvantages. The transmissio...
