Clutches and Brakes 42,133 Items
Description: Power transfer via a clutch or brake is a method of transferring energy from a rotating device to another non-static device. The clutch is used to help bring the second non-rotating device to the same speed as the rotating one. In a brake, the non-rotating device is fixed so that the driving device comes to stop. The ultimate impact is that both devices are able to rotate at the same speed or stopped. The main method of engagement is the friction and jaw. There are two main types of brake and clutches: The friction clutches and brakes: This model employs friction disc to transfer torque from one rotating device to another rotating member. Friction discs are designed with smooth flat surfaces that alternately attach to the rotating and non-rotating members. The sequence, friction surface, and load presented to the clutch/brake determine the size and number of friction surfaces used for transmitting torque. When the capacity of a disc friction surface is surpassed, the device starts to slip. Slipping is also reported during engagement and disengagement. This allows the machine to have a smooth transfer of torque. Jaw/ tooth clutches and brakes: These types of clutches and brakes use serrated teeth design that helps to absorb or transfer energy from a rotating device to another member. The friction between the teeth surfaces of the rotating and stationary member makes it possible to transmit torque or stop the engine. When selecting the clutch and brakes for your system, it is prudent to ensure you understand the challenges associated with each. For example, the friction type is largely affected by usage wear and dust while jaw and tooth largely suffer from a backlash. Therefore, it is recommended that you use an expert so that only the best clutch and brakes are selected. You should also ensure that the system is maintained in top condition for higher output.
