The small and versatile helpers
As a manufacturer, quality supplier and technology partner, Dr. TRETTER will be focusing on tolerance sleeves at Motek - smart connecting elements that can be used in a variety of ways. As a shaft-hub connection, tolerance sleeves save time-consuming, cost-intensive reworking. They also enable the fastening of roller or plain bearings despite different thermal expansion of the connecting parts.
Tolerance sleeves are slotted rings made of spring band material with wave-like characteristics. The operating principle of this spring-elastic connecting element can be illustrated by many small compression springs distributed around the circumference. These are pre-tensioned when the tolerance sleeve is pressed in, creating a friction-locked connection. Larger tolerances of the connecting parts and center offset or misalignment can also be compensated for. In contrast to pressing or gluing, connections can be released again once they have been created. This saves costs and increases protection against damage.
In drive technology, the tolerance sleeves are used, for example, in the mounting of electric motors and pumps, stator fastening and fixing of add-on parts such as rotary encoders, fans, pulleys and pump wheels.
A new addition to Dr. TRETTER's wide-ranging product portfolio at the trade fair stand will be trapezoidal screws. These can be an economical alternative to the more expensive and more precise ball screws for certain applications. The quality supplier specializes in the end machining of the screw drive according to customer drawings for small or large quantities.
The new shaft couplings from Dr. TRETTER provide a flexible coupling between the drive and the ball or trapezoidal screw drive. With the help of this connecting element, center misalignment and misalignment errors can be compensated and vibrations and shocks in the drive train can be minimized.
