Rope Drive:
A rope drive is a type of positive drive where power is transmitted from one pulley to another using a flexible rope. It is commonly used in applications where there is a need for large speed reduction or where space constraints exist. However, a rope drive is not a positive drive as there is a possibility of slippage between the rope and the pulleys, especially when the tension in the rope is not high enough.
V-Belt Drive:
A V-belt drive is a type of positive drive that uses a V-shaped belt to transmit power between two pulleys. The belt is wedged between the sides of the pulleys, providing a positive grip and minimizing the chances of slippage. V-belt drives are widely used in various applications due to their high efficiency, compact design, and ability to transmit high torque.
Flat Belt Drive:
Similar to a V-belt drive, a flat belt drive is also a type of positive drive that uses a flat belt to transmit power between two pulleys. The flat belt is in contact with the pulleys' surfaces, providing a positive grip and ensuring power transmission without slippage. Flat belt drives are commonly used in applications where high speeds are required, but they have lower power transmission capabilities compared to V-belt drives.
Chain Drive:
A chain drive is a type of positive drive where power is transmitted using a chain. It consists of a series of interconnected links that mesh with sprockets on the driving and driven shafts. Chain drives are known for their high power transmission capabilities, ability to operate at high speeds, and resistance to wear and fatigue. They are commonly used in applications such as bicycles, motorcycles, and industrial machinery.
Conclusion:
Out of the given options, the positive drive is the chain drive. It provides a reliable and efficient means of power transmission, making it suitable for various mechanical applications. Rope drives, V-belt drives, and flat belt drives are not considered positive drives due to the possibility of slippage between the flexible elements and the pulleys.
