The included angle of cross section of a V-belt is usually
30°to 40°
The usual textbook included angle for a conventional V-belt is about 40°, which lies in the listed 30°–40° range. Actual belt and pulley-groove angles depend on the belt design.
In a multiple V belt drive, when a single belt is damaged, it is preferable to change the complete set to _____.
In a compound belt drive, an engine pulley A of dia.750 mm rotating at 150 RPM drives pulley B of dia. 450 mm.Pulley C of dia. 900 mm keyed to the same shaft of pulley B drives dynamo pulley of dia. 150 mm. Speed of dynamo pulley is
In belt drive power transmitted is given by:
(Where Tt, Ts, and v are tight side tension, slack side tension and linear velocity of belt respectively)The mass of the belt per unit length in belt drive of pulleys is 10 kg/m. The maximum tension in a belt is 3000 N. The velocity of the belt for maximum power transmission:
If the tension in tight side and slack side of the belt is 3000 N and 1500 N, respectively. The effective driving force at the circumference of the driven pulley is given by:
