Design of Measurement Device for Belt Tension of Locomotive Air Compressor
Air braking is generally adopted in railway locomotives.The air source of air braking comes from air compressor,and belt transmission is adopted between air compressor and power source.In the design of belt drive,the tightness of the belt must be considered.Too loose or too tight belt installation will have adverse effects.If the belt is too loose,it will slip and affect the transmission effect.Belt installation too tight will increase wear and reduce belt life.In the design of belt drive,the tightness of the belt drive is judged by the force and deflection of the belt,and the force and deflection of the belt can be obtained by calculation.However,in the actual installation process of the belt,because the force and deflection of the belt can not be accurately measured,the tightness of the belt is usually judged by pressing by hand,resulting in an unreasonable tightness of the air compressor belt.In order to ensure the moderate tension degree of air compressor belt installation,this paper designs a belt tension degree detection scheme,which determines whether the belt tightness meets the installation requirements by detecting the pressure and deflection of the belt installation respectively.The scheme is convenient in operation and low in cost,and can realize the function of detecting the tension degree of air compressor belt.
