The Torsion Testing Machine is a compact machine, ideal for classroom demonstrations and for safe use by small groups of students.
Its frame is a rigid, precision-engineered alloy box-section, supported at each end by adjustable feet. It carries two main parts:
A torque reaction and measurement system at the other.
A strain head at one end.
The strain head is a 60:1 worm drive reduction gearbox, mounted on a platform. The platform can be moved and locked to any point along the frame. To apply torque, students turn a handle at the input of the gearbox. A keyway allows the output shaft of the gearbox to slide freely along its length. This allows for any change in length of the specimen during the tests and for easy insertion of specimens.
The specimens fit between the strain head and the torque reaction and measurement system.
Hexagonal drive sockets hold the test specimens. The sockets fit on the gearbox output shaft and the torsion shaft. lsskenya supplies two different sizes of drive sockets.
The torque reaction and measurement system includes a torsion shaft supported by bearings. The shaft reacts on a strain-gauged load cell. A digital display shows the force measured by the load cell.
