Torque limiters and safety clutch couplings are ideally installed as physically close to the point of impact or overload as possible in order to enhance sensitivity. As with flexible couplings, the appropriate size will be found once the correct torque rating has been determined. The appropriate safety clutch will be set to disengage at a point slightly higher than the peak torque required for normal operation. Standard safety couplings will attempt to re-engage automatically at periodic points until the torque is reduced to an acceptable level.
Torque limiters are often used in conjunction with a proximity sensor to detect the movement of an external ring around the disengaging safety clutch, and then trigger an e-stop condition in the machine. Free wheeling safety clutches will permanently separate the drive and driven shaft hubs of the coupling, requiring a manual re-engagement. This cuts back significantly on potential wear between the two halves of the torque limiter as they ratchet against each other.
Q. How do motors interface with the TwinSpin reducers?
A. Standard motor interfaces permits direct keyed servo motor shafts that match standard reducer input bores to be directly plugged into the reducer. We offer a complete range of motor mounting flanges. Additional, we can accommodate non-standard motor shafts with input collets, extension shafts or zero backlash couplings.
Q. I need very low inertia and weight, will TwinSpin meet these needs?
A. Size for size, TwinSpin delivers a complete range of Cycloidal reducers from the smallest unit at 50 mm through largest 335 mm diameter. TwinSpin is a complete solution including dual cross-roller bearings and dual output flanges. Delivering the highest torque density of any of the reducers on the market.
Q. We are looking for the smallest sized unit available, is there a version of TwinSpin that’s available in a small package?
A. The TwinSpin TS050-M series is a complete solution in a compact 55 mm package. The TS050-M has 18 Nm of nominal torque and 36 Nm of acceleration torque, the compact high-speed input shaft arrangement also has lower input inertia for more dynamic responsiveness.
Q. What additional components, e.g. bearings output flanges, etc. will I need to integrate the TwinSpin into my application?
A. The short answer… nothing! All of the TwinSpin reducers are a complete solution, virtually plug and play.
Q. How is a non-standard motor shaft interfaced with the TwinSpin reducers?
A. TwinSpin reducers can accommodate non-standard motor shafts with an number of options, ranging from; input collets, extension shafts or zero backlash couplings. Custom solutions are also an option, to meet the demands of the application.
