Shaft Coupling Description
TRASCO ES 48 GESS (GESS48) - Spacer (Al Alloy) is a part designed for SIT TRASCO ES zero-backlash shaft couplings. It is made of aluminium alloy.
SIT TRASCO ES are torsionally flexible, puncture-proof shaft couplings with two metal hubs with front claws and a polyurethane element. They transmit torque through a high-precision pressure-stressed elastic star-shaped buffer which absorbs shock and torsional vibration. The spacers are then the center parts into which the elastic elements with hubs are inserted on both sides. Hubs and spacers are manufactured with minimal backlash so that the flexible elements are very tightly inserted into the front teeth to make a so-called zero-backlash coupling. These GESS spacers are made of aluminium alloy.
Construction
- Hubs of various type
- Elastic star-shaped elements
- GESS spacer
Typical Applications
SIT TRASCO ES zero-backlash elastic couplings with GESS double shaft spacers are intended for the highest demands in a wide range of industries where the highest precision and minimum backlash are required.
They are used, for example, in machine tools, testing machines, fine mechanics, dynamometers and many other applications, particularly in the food, chemical, paper, metalworking and automotive industries.
Properties
- Torque transmission without backlash
- Vibration damping from the motor shaft (up to 80%)
- Easy and quick installation
- Couplings are resistant to oil, chemicals and high temperature
- Small size, low moment of inertia
