More torque can't hurt
Reliance Precision Mechatronics has introduced a high torque extension to its range of spiral beam couplings. The target was to increase the maximum torque so the couplings could be used for heavy duty measurement applications and in linear drives. In this new version, the higher torque capacity is achieved by using multi-beam helixes, with the largest offering a maximum torque of up to 22Nm. These new couplings combine high torsional stiffness with low radial stiffness, thus protecting the bearings and the shafts of the connected drive parts. The couplings are manufactured in one piece, having no moving parts avoids friction loss and the design guarantees good vibration damping.
The bore of the helix section is standard, allowing shafts to be placed into the coupling without affecting function. Feather key grooves are also available. The couplings can be supplied in a range of sizes with outer diameters from 9.5mm up to 38.1mm and an overall length from 14.2mm up to 66.7mm. Bores are available from 2mm up to 22mm, with clamp or set screw type fixing hubs. Alternative bore combinations are also possible.
The couplings can be supplied in aluminium or stainless steel, allowing them to be used in various applications such as those requiring a high temperature range or the food industry. These couplings are suitable for heavy duty rotary position transducers, servo and stepper motors, mechanical and mechatronic drive assemblies and in automation applications.
