Introduction to clutches and brakes, and ball screws and linear bearings
Several industrial applications, such as some conveyors, may require a load to be engaged/disengaged or braked while the motor keeps running. Other applications require the torque to be limited to protect mechanical equipment from overload caused by shock loads or machine jamming. The topic “Clutches and brakes” introduces those aspects and presents clutches for various operating conditions along with their proper installation procedure.
In modern industry, ball screws and linear bearings are commonly used to transform rotational movement into linear movement, and vice versa. Typical applications include many types of machine tools, such as CNC mills and drills. The topic “Ball screws and linear bearings” introduces the main components and proper assembly steps of a linear slide. Essential concepts of maintenance and lubrication of linear bearings, ball screws, and ball nuts are also covered.
