Chain Drive for Constant Velocity Ratio

Introduction:
In mechanical engineering, power transmission is an essential concept. It refers to the mechanism used to transmit power from the source to the destination. There are various types of power transmission drives available in the industry, and each type has its own unique features and benefits.

Types of Power Transmission Drives:
The four most commonly used types of power transmission drives are gear drive, flat belt drive, chain drive, and V-belt drive. Each drive has its own unique features and benefits. However, for a constant velocity ratio, positive drive with large center distance between the driver and driven shafts, chain drive is the best option.

Reasons for Choosing Chain Drive:

1. Constant Velocity Ratio:
Chain drives provide a constant velocity ratio between the driver and driven shafts. This means that the speed of the driven shaft remains constant, regardless of the load or torque applied to it. This is ideal for applications where a constant speed is required.

2. Positive Drive:
Chain drives are positive drives, which means that they do not slip. This is because the chains are in direct contact with the sprockets, and there is no slippage between the two. This makes chain drives ideal for high torque applications.

3. Large Center Distance:
Chain drives are ideal for applications where there is a large center distance between the driver and driven shafts. This is because the chains can easily span the distance between the two shafts without the need for intermediate support.

4. Durable and Reliable:
Chain drives are very durable and reliable. They can withstand high loads and are not affected by dust, dirt, or other contaminants. This makes them ideal for harsh environments where other types of drives may fail.

Conclusion:
In summary, for a constant velocity ratio, positive drive with large center distance between the driver and driven shafts, chain drive is the best option. It provides a constant velocity ratio, is a positive drive, can span large distances, and is durable and reliable.

It is noisy and as the positive fault free drive as it cannot slip. It is essential that these drives are efficiently lubricated and tollay inclosed and perfectly made to run through oil path.
