Chain drives are flexible and made of number of links and its a intermediate between belts and gears drives Chains can only be used to transmit power between parallel shafts Unlike belt drives chain drives uses special toothed wheels called sprockets Classification of chainsget price

Belt and Rope Drives Brakes

Belt and Rope Drives Brakes In most cases the power transmitted relies upon the friction between the rope or belt and the rim of the pulley However in the case of toothed belts and chains friction does not play a beneficial part no slip is allowable and a precise relationship between the movement of the pulleys is obtained get price

Belt and Chain Drives (Flexible Drive Elements)

Fatigue of Wire Rope Fig 17–21does not preclude failure by fatigue or wear It does show long life if p/S u is less than 0 001 Substituting this ratio in Eq (17–42) Dividing both sides of Eq (17–42) by S u and solving for F gives allowable fatigue tension Factor of safety for fatigue is Shigley's Mechanical Engineering Designget price

Applications of Belt and Rope Drives in Textile Industry

Transmissions of power by belts and ropes The belts and ropes transmit power through the friction between belt or rope and rim of the pulley The function of a belt and rope drive is to transmit rotational motion and torque from one shaft to another smoothly quietly and inexpensively get price


Aug 24 2015POWER TRANSMISSION DEVICES The power is transmitted from one shaft to the other by means of belts chains and gears The belts and ropes are flexible members which are used where distance between the two shafts is large The chains also have flexibility but they are preferred for intermediate distances get price

Hoisting Rigging Fundamentals

rope passes over a sheave increased fatigue is achieved in a rope design by using a large number of wires It involves both the basic metallurgy and the diameters of wires In general a rope made of many wires will have greater fatigue resistance than a same-size rope made of fewer larger wires because smaller wires have greater ability toget price

Belt Drives Types Slip Creep [Advantages Disadvantages]

V-belt may be operated in either direction with the tight side of the belt at the top or bottom Therefore the power transmitted by v-belts is more than flat belts The centre line may be horizontal vertical or inclined Selection of Belt Drive The following factors are considered in the selection of belt drives get price

Chain Drives

Chain Drive Design Factors The slack in the chain should be on the bottom strand The chain should wrap the sprocket at least 90 degrees Chain wrap of 120 degrees is more desirable With vertical chain drives the chain tends to hang away from the lower sprocket especially when the driver sprocket is in the lowest position Arrange the shaft get price
