Cottered is a term often used in the context of bicycles and motorcycles. It refers to a type of joint used to connect mechanical components, such as a crank arm to a pedal or a chainwheel to a crankshaft. In the case of bicycles, cottered joints were commonly used in older models before more modern mechanisms like square taper bottom brackets and splined interfaces became prevalent.

Function of Cottered Joints

Cottered joints provide a secure and reliable way to connect components in a mechanical system. They typically consist of a pin (known as a cotter) that is inserted through holes in the components to be joined and secured with a nut on the other side. This setup ensures that the components are held firmly in place and can withstand the forces and stresses they are subjected to during operation.

Installation and Maintenance

When installing or maintaining cottered joints, it is crucial to ensure that the cotter pins are properly aligned and tightened to prevent any play or slippage in the connection. Over time, cotter pins may wear out and need to be replaced to maintain the integrity of the joint. Regular inspection and maintenance of cottered joints are essential to prevent issues such as loosening or failure during use.

Advantages and Disadvantages

One of the main advantages of cottered joints is their simplicity and ease of installation. They are also relatively inexpensive compared to other types of connections. However, cottered joints can be more prone to wear and loosening over time compared to more modern alternatives. They may also require more frequent maintenance to ensure optimal performance.

In conclusion, cottered joints are a traditional yet effective way to connect mechanical components in bicycles and motorcycles. While they may not be as common in modern designs, they still have their place in certain applications where simplicity and reliability are essential.
