Description
Technical Field
The invention relates to a belt installation tool, in particular to an elastic belt installation tool.
Background
The engine front end wheel train system generally comprises accessories such as a crankshaft belt wheel, an air conditioner, a water pump, a belt and the like. The belt is responsible for effectively transmitting the power output by the crankshaft of the engine to the air conditioner and the water pump, and the elastic belt is generally used at present to meet the use requirement of a front-end wheel train system due to the fact that driving accessories are few and transmission torque is small. The elastic belt is stretched in a static state in a working state, and the belt generates certain tension by means of the stretching deformation so as to ensure the stable operation of a front-end wheel train system. Elastic belts have advantages of light weight, low cost, compact structure, etc. because they do not require a tensioning system, and are increasingly used in engines. The elastic belt guarantees the tension force through the elasticity of the elastic belt, so that the belt needs to be stressed and stretched before entering a pulley groove during installation, and therefore the assembly is difficult frequently, and an installation tool needs to be used. The existing auxiliary installation tool for the elastic belt has the defects that the elastic belt has a certain violent operation process when being forcibly stretched and falls into a wedge groove of a belt wheel, and the method is generally used under the condition that the requirement on the tension of the belt is low, such as a three-wedge belt or a V-belt. For the installation of 5-wedge or higher tension elastic belts, the existing belt auxiliary installation mechanism is easy to cause the damage of a belt wedge surface when in use. Meanwhile, when the elastic belt in the prior art is initially installed, the problem that the elastic belt is separated from the installation tool exists, so that the elastic belt and the auxiliary installation mechanism need to be manually tightened during initial installation, and the assembly efficiency is low.
