  • BELT-CHAIN-GEAR DRIVES

    BELT-CHAIN-GEAR DRIVES

    BELT-CHAIN-GEAR DRIVES   Advantages of V-Belt over Flat Belt Friction is more due to groove (wedge). Thus these transmit more power. Reduced angle of contact and hence more power is transmitted There is no slip in a V-belt since belt runs in a groove.  Compact since distance between two shaft axes is less. Silent drive. It […]

  • FLAT BELT DRIVE

    FLAT BELT DRIVE

    FLAT BELT DRIVE POWER TRANSMISSION The power is transmitted from one shaft to the another shaft by a belt, chain and gear drive. The belts and ropes are used where distance between the two shafts is large. The chains are used for intermediate distances. The gears are used for shorter distance between the shafts. Gear […]

    * SLIP AND CREEP

    SLIP AND CREEP Slip is there when belt does not grip pulley fully and perfectly. Thus,  there is not full friction between the pulley and the belt. Thus, there will be slip between the driver pulley and belt. There will be slip between the belt and driven pulley. SLIP BETWEEN DRIVER PULLEY AND BELT This […]
