Pulley type and size

                                                                Pulley type and size

Pulley for v-belt, more countries of the specifications of the pulley is divided into A, B, C, D, E, O and other models, is according to different size of pulley back width and height to decide A, B, C, D, E, O different models of belt pulley on the back width, height and size are different, so there are different slot type, type A pulley width is 12.5 mm, 9 mm in height and width of the top is 13 mm, thickness of 8 mm; Type B pulley width is 16.5 mm, height is 11 mm, the top width of 17 mm, the thickness of 10.5 mm; C type pulley width is 22 mm, height is 14 mm, width of the top is 22 mm, the thickness of 13.5 mm; Type D pulley width is 21.5 mm, width is 19 mm, top width of 21.5 mm, width is 19 mm; E the pulley is 38 mm in width, height is 25.5 mm, the width of the top is 38 mm, thickness of 25.5 mm; O the pulley is 10 mm in width, height is 6 mm.

Different models are different, the pulley consists of ordinary, ordinary reinforced and strong narrow V belt, narrow V belt. Ordinary include A, B, C, D, E, O 8, 3 V, 5 V, V, ordinary reinforced CX, DX, EX, including AX, 3 vx, 5 vx, 8 vx, narrow V belt including SPZ, SPA,.spb, SPC, strong narrow v-belt including XPA, XPB, XPC.

Pulley type size

Different models have different size of pulley, general pulley groove Angle of 34 degrees respectively, 36 degrees, 38 degrees of three. O pulley of belt wheel radius is 34 degrees in 25 mm to 35.5 mm; In the 35.5 mm to 45 mm to 36 degrees, more than 45 mm is 38 degrees; Type A pulley of belt wheel radius is 34 degrees in 35.5 mm to 50 mm, 50 mm ~ 62.5 mm to 36 degrees; When more than 62.5 mm is 38 degrees; B type pulley of belt wheel radius is 34 degrees in 62.2 mm to 80 mm, 80 mm to 100 mm to 36 degrees, more than 100 mm is 38 degrees; C type pulley wheel radius is 34 degrees in 100 mm to 125 mm and 125 mm ~ 157.5 mm is 34 degrees, 125 mm ~ 157.5 mm to 36 degrees, more than 157.5 mm is 38 degrees; Type D pulley of belt wheel radius of 157.5 mm ~ 225 mm to 36 degrees, more than 225 mm is 38 degrees; E pulley of belt wheel radius at 250 mm to 315 mm to 36 degrees, more than 315 mm is 38 degrees.

Pulley transmitted compared to other more stable, less noise, vibration amplitude is smaller, because of its simple structure and more convenient adjustment, so in many places to see in teleportation pulley. When buying and installing pulley should carefully check, make sure that the pulley without scratching the surface of the phenomenon, and ensure the size of pulley strictly conform to the standards, both in the installation and remove aspects shall comply with the relevant notice
