[Technical field]

[0001] The present disclosure relates to a method for manufacturing a casing that includes mating inner components and a casing that are attached together using a washer. As a non-limiting example, the device may include a torque up It can be used for assembly. [Background technology]

[0002] The torque assembly receives torque from a torque supply input (e.g., a shaft). To regulate or enhance the amount of torque transmitted to an input output (e.g., an appliance) The torque assembly may be used to limit or limit the torque of the transmission. Provides rotating mechanical power within the power system, preventing damage to mechanical equipment Torque assemblies are used in many types of transmission systems. It is possible to limit the torque or provide torque overload protection. Torque assemblies are used in many types of transmission systems. In some applications, the torque supply input can be wind, water, It may be connected to a torque generating device powered by steam, gas, etc. In some variations, the torque-receiving output requires the input of torque for operation. It can be a generator, a tool, or an industrial machine.
