Application of cylindrical gear reducer
Combined with the actual situation and the existing equipment, finally decided to choose second ways, namely the installation of speed reducertorque sensor in front. In order to protect the motor when starting, avoidtoo big for the motor and the impact of power grid, the no-load or light loadstart, also must choose to use soft start device suitable. In order to ensure the safe operation of the station, select the hydro viscous soft startdevice, because the starting torque of liquid viscous soft start device can provide a smooth, adjustable, the impact force is small, the installation of Hydroviscous soft start device through the coupling or connected to thewheels directly and motor.
Control system: because the PLC is a digital computing operating systemspecialized in industrial environment application design and development, has high reliability, strong anti-interference ability, strong universal property, debugging and convenient maintenance and so on, so in the design ofexperimental platform of choice the programmable controller of SIEMENS's production, programming software is used by STEP7-Micro/WIN. in the light of the above, the final to determine the overall design scheme of disc brakeexperiment device, as shown in figure 1. The test stand is mainly composed of motor soft start, soft start device, hydraulic station, speed and torquesensor, speed reducer, brake disc and brake hydraulic station, PLC control system, etc..
Disc brake device is the main topic of this is the KZP series since the coldtype control device. Combined with the company and equipment allow, choosefrom the cold disc brake device for testing KZP-1000/2 x 100 model, themaximum braking torque 45kNm, 330mm brake disc brake radius, the maximum speed of 170r/min., considering the actual situation, is not the maximum brake torque for large brake torque of disc brake, but can according to the law of similarity, similarity law is an important law is applied to the fanand pump, liquid viscous soft starting device to select indicators is the main motor power, according to the power of liquid viscous soft start deviceshould be considered the standard is greater than the output power of motor,reducer cone DCY-355 model of cylindrical gear reducer, the transmission ratio i=71, the maximum speed is n=1500r/min, meet the test requirements.
