Which parameters are required for the selection of the pulley
Very simple; A few parameters: motor power, master slave speed ratio (which is fast speed/slow speed) Example: the motor speed of 1450 RPM/sub-unit 900 / min motor power 7.5 KW The speed ratio = 1450/900 = 1.61 Compare the power table to the A band (0-7.5 KW choose A with 7.5 to 20). According to each belt load power to select the most reasonable small wheels With total power (power rating is the X factor of safety (safety coefficient is condition coefficient is generally between 1.3-2.5))/each belt load power = number of belt Large wheel = small wheel size ratio
Four data is needed Choose A belt (e.g. A, B, C) that is the size of your torque A few belts are also chosen according to the torque The diameter of the shaft of the inner hole The outer diameter is calculated according to the required speed
Example: ordinary cutting machinery tire passive wheel is 2 a natural choice 2 a driving wheel motor is level 2 2.2 measurement is 28 cutter need to input speed 2800 motor speed is 2800 passive wheel is 1:1 so driving wheel 90 and 90 of the pulley has a complete model of: 2 a * 28 * 90 a total of four data
