FUNCTIONALITY OF THE SHAFT-HUB CONNECTION
At TRETTER AG, tolerance sleeves are manufactured from high-quality, hard spring steel. A shaft-hub connection typically consists of three components:
1. Shaft = inner component
2. Tolerance sleeve
3. Housing = outer component The interaction of the three components enables the component to be used, for example, in the following technical problems:
– Different thermal expansions
– Vibrations, oscillations, noise
– Torque limitation
– Axial forces
– Torque transmission
– Misalignment, center offset
– Bridging large tolerances
FUNCTIONAL AREAS
OF THE TOLERANCE SLEEVE
Connecting element
The tolerance sleeve, clamped between two components, acts as a non-positive connection.
Slip clutch / overload clutch
The tolerance sleeve is used as a slip clutch, a mechanical overload protection device that allows two connected components to move relative to each other if a certain torque is exceeded.
Torque transmission
As with a parallel key, torque transmission can be achieved with a tolerance sleeve.
Adjustment / positioning (friction element)
The tolerance ring offers the possibility of changing the position and enables adjustment of the components to each other.
