"SPIETH design" clamping sets are friction-locked connecting elements used in general mechanical engineering. Arranged between cylindrical shafts and hub bores, they are capable of transmitting high torque levels and/or axial forces. Their high centring capability, dynamic symmetry and the ease of dismantling afforded by the use of spring hardened steel make them ideal for application wherever precise concentricity is called for, where high rotational frequencies are involved, or where exchangeable components require connecting.

Typical application examples include the fixture of gears, connections to modern working spindles, the fixture of profile rollers and many more. However, this system is not reserved to this type of complex application and can be used at reasonable cost for all kind of shaft-hub connections.

Following practical examples will give an overview of different applications.
 

Example 1: Gear fixture. For precise concentricity requirements, we recommend mounting a control facility to proofe or adjust with the clamping screws during assembly.

Example 2: Pulley fixture. The hub can be made of an aluminium alloy. Observe minimum strength. High temperatures can impair the retention force!

Example 3: Pressure roller fixture. Here, two long clamping sets are used to achieve high overal radial rigidity due to intensive tensioning of the shaft hub. The pressure roller is exchanged by pulling the shaft out of the bearings.

Example 4: Rocker arm fixture. The peripheral and axial position can be ideally adjusted during assembly.

Back

Example 5: Jaw clutch fixture. No grooves, shaft shoulders etc. A reasonably priced but highly effective connection.

Example 6: Fixture of a guide column to the machine body.

Back

Example 7: Flywheel fixture. On a high-speed rotating working spindle, the arrangement of the precisely concentric flywheel can help reduce the installed drive output.

Example 8: Two shafts rigid coupled by using clamping sets. Due to possible overdefinition, attention must be paid to the admissible rotating bending stress.
