Heavy-duty spiral beam couplings transmit high torques
Reliance Precision Mechatronics is introducing heavy-duty spiral beam couplings. The aim of the development programme 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, thereby protecting the bearings and the shafts of the connected drive parts. The couplings are manufactured in one piece - having no moving parts avoids friction losses and ensures good vibration damping.
The bore of the helix section is standard, so shafts can be positioned within the heavy-duty beam couplings 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 overall lengths from 14.2mm 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.
Reliance is offering the its heavy-duty beam couplings in aluminium or stainless steel for use 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.
