What type of washer is specified for mounting a governor?

A cut washer is specifically designed for applications where a secure fit is essential, such as mounting a governor. The cut washer features a section that is not fully round, which helps it grip the surface more effectively. This grip minimizes the risk of loosening due to vibration or other forces that may be present in mechanical operations.

In the context of mounting a governor, which controls the speed of an engine or turbine, the need for a secure and stable mounting is critical to ensure precise functionality and avoid failure during operation. The cut washer serves this purpose well by providing a reliable hold to keep components aligned and in place.

Other types of washers, while useful in various applications, do not offer the same benefits in this context. Flat washers, for example, distribute load but do not prevent loosening effectively. Split washers can provide some locking characteristics, but they are typically used in less critical applications than a cut washer might be. Spring washers also provide tension but are generally meant for dynamic or compressive applications, not for mounting where stability is paramount.
