Belt wheel of automobile engine

Abstract

The invention discloses a belt wheel of an automobile engine. The belt wheel comprises a belt wheel body, wherein retaining rings are separately arranged at the left and right ends of the outer circumferential surface of the belt wheel body, a middle distance ring is arranged on the left part of the outer circumferential surface of the belt wheel body, gear tooth spaces are uniformly arranged between the middle distance ring and the left and right retaining rings, separately; transmission belts matched with the gear tooth spaces are separately arranged on the outer sides of the left and rightgear tooth spaces; and round slots are formed in the middle parts of the left and right ends of the belt wheel body. The belt wheel disclosed by the invention is simple in structure, and convenient tomount and detach and maintain and replace parts. By arranging two transmission belts different in width, the transmission safety of the belts of the engine is improved; by arranging the retaining rings, the condition that the belt is easy to pull away in the working process of the belt wheel is avoided, and the working stability is improved. Ventilation and heat dissipation can be effectively carried out on the contacts of the transmission belts and the belt wheel body, so that the service lives of the transmission belts are prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile transmission components, and the specific field is an automobile engine pulley. Background technique [0002] The car engine is the engine that provides power for the car. It is the heart of the car and affects the power, economy and environmental protection of the car. According to different power sources, automotive engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids. Common gasoline engines and diesel engines are both reciprocating piston internal combustion engines, which convert the chemical energy of fuel into mechanical energy of piston movement and output power to the outside. Gasoline engine has high speed, low mass, low noise, easy starting, and low manufacturing cost; diesel engine has large compression ratio, high thermal efficiency, and better economic performance and emission performance than gasoline engine. The belt pulley belongs...

Problems solved by technology

In the prior art, with the high-speed rotation of the pulley, when the belt wears too much, it is easy to cause transmission failure. The outer cylindrical surface of the pulley rubs against the belt to generate a large amount of heat, which cannot effectively dissipate heat, so that the transmission efficiency of the engine is not high. The belt is easy to fall out during the working process of the pulley, and the working stability is poor
