Abstract

The invention discloses a mounting structure of an engine accessory belt pulley. The structure comprises an engine accessory and an accessory belt pulley, wherein, one end of the accessory belt pulley is installed in a bracket with a bearing which is coaxially installed in the bracket and is fixed by a retainer ring, one end face of a bearing end cover is connected with the bracket, the other end face is connected with the convex shoulder of the engine accessory, and one end of the engine accessory is installed in the accessory belt pulley on which an adjusting shim is installed; the adjusting shim is firstly installed on the accessory belt pulley, and the accessory belt pulley on which the adjusting shim is installed is arranged in the bracket with the bearing. The mounting structure of the engine accessory belt pulley, which is provided with the special structure, increases supporting points by utilizing the bearing to support the accessory belt pulley, and causes the supporting points to be closer to a stress point, thereby reducing the distance of a suspension arm, improving the bent torque of the engine, prolonging the service life and reducing the outline dimension of the engine accessory, and finally, the over-all properties of the engine is improved.

Description

technical field [0001] The invention relates to an installation structure of a pulley, in particular to an installation structure of an engine accessory pulley which can share the force of the engine accessory to improve the performance and life of the engine accessory. Background technique [0002] In the engine drive system, since the accessory system is mostly driven by a belt, and the accessory belt is driven by the accessory pulley to drive the accessory system, the accessory pulley plays a vital role in the entire engine accessory system. [0003] Engine accessories are subjected to complex forces, which are subject to large forces in all directions and are also affected by bending moments and torques. Especially when the engine is working under variable conditions, it is necessary to consider the influence of various factors such as temperature, frequency, and vibration. So that the stress of the accessory pulley is very complicated. These complex forces are finally ...
