Cup roller clutches are mechanical devices designed to allow motion in one direction while preventing it in the opposite direction. They consist of a cup-shaped outer casing that houses a series of rollers, which engage with an inner race. This design enables efficient torque transmission and is commonly used in various applications, including automotive and industrial machinery.
The functionality of cup roller clutches relies on the interaction between the rollers and the surfaces of the cup and inner race. When torque is applied in the permitted direction, the rollers are forced into contact, locking the components together. Conversely, when torque is applied in the opposite direction, the rollers disengage, allowing free movement.
These clutches are valued for their compact design and high load capacity, making them suitable for applications where space is limited. Their reliability and efficiency contribute to their widespread use in systems requiring controlled motion and torque management.
