What is the diameter of the belt wheel
You're not talking about the rated power of the motor. For the moment, you are using A type A belt. Take the pump for the speed of 750, and get the transmission ratio I = 1.87 So d1 = I * d2 Small wheel diameter on the motor: d2 = 155mm The design manual of mechanical design, the 160mm in the A band is in accordance with the design requirement
Leather belt wheel, belongs to the plate of the plate, the general relative size is larger, the manufacturing process is usually cast, the forging is given priority to. Standard regulations of the state, the belt type O, A, B, C, D, E, F seven kinds of models, there are three kinds of corresponding pulley wheel groove Angle 34 °, 36 °, 38 °, and rules for each triangle model corresponding to the minimum diameter of each small pulley groove Angle, large pulley provisions have been made. The grooves of the pulley are divided into 32 degrees 34 degrees 36 degrees 38 degrees, depending on the grooves and the base diameter of the belt wheel. The grooves of the pulley are related to the diameter of the pulley.
The angles of the grooves of different types of pulley are recommended in different diameters: The o-type pulley is 34 degrees in diameter from 50mm to 71mm. At 71mm ~ 90mm, it is 36 degrees, > 90mm is 38 degrees. The type A pulley is 334 degrees in diameter from 71mm to 100mm, and 36-degree > 125mm when 100mm ~ 125mm. The type B pulley is 34 degrees in diameter from 125mm to 160mm. 160mm ~ 200mm is 36 degrees, > 200mm is 38 degrees; The c-type pulley is 34 degrees in diameter between 200mm ~ 250mm, 36degree for 250mm ~ 315mm, and 38 degrees for > 315mm. The d-type pulley is 36 degrees in diameter from 355mm to 450mm, and 38 degrees for > 450mm. The E type 500mm ~ 630mm is 36 degrees, > 630mm is 38 degrees.
