Abstract

The invention provides a belt wheel guide structure and an engine. The belt wheel guide structure comprises a belt wheel train and a guide body; the belt wheel train comprises a belt wheel and a beltwhich is arranged on the outer circumference face of the belt wheel in a surrounding manner and is driven by rotation of the belt wheel to move; the guide body is located on the rotation plane of thebelt wheel, the guide body is located on one side of the belt wheel, the guide body is provided with two ends bent towards the belt wheel, the inner side of the end of the guide body makes contact with the belt on the two sides of the belt wheel, and the included angle formed by the connecting line between each of the two ends and the axis of the belt wheel is larger than the wrapping angle of thebelt wheels. Under the condition that the belt wheel guide structure occupies small space, the wrapping angle of the belt wheel is increased, the slippage risk caused by the too small wrapping angleof the belt wheel can be avoided, the structure is simple, the mounting manner is flexible, the cost is low, and the structure can be used for the wheel train with the compact and complex structural space.

Description

technical field [0001] The invention relates to a pulley guiding technology and an engine, in particular to a pulley guiding structure and an engine. Background technique [0002] During the arrangement of the engine gear train, there will be a phenomenon that the wrap angle of the pulley is too small. If the wrap angle is too small, the friction force between the belt and the pulley will be too small, resulting in belt slippage and other phenomena, which will affect the transmission efficiency of the engine. [0003] In the prior art, the wrap angle of the pulley is usually increased by adding an idler between the two pulleys, wherein the idler is a smooth pulley, and the idler is set between the two pulleys. The outer side of the loose edge makes the loose edge belt between the two pulleys press to the inner side, thereby changing the direction of belt transmission and increasing the wrap angle of the pulley. [0004] However, when the space of the wheel train is compact ...
