What is the length of the ribbon
LP = 2a + PI (d1 + d2) + (d2 - d1) / 4 * a Lp: belt length (mm) D1 d2: the diameter of the active belt wheel and the drive belt wheel (mm) A: two wheel drive center distance (mm)
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. In general, the design of a large size is made of cast iron, and the materials are usually cast iron (the casting performance is better), and the casting steel is seldom used. The general size is small, can be designed to be forged, the material is steel.
So let's figure out the circumference of the wheel of R2 and figure out the circumference of the wheel of R3 minus R3 divided by 2 It's the error of the two belts
