Animation of a cycloidal drive. A cycloidal drive or cycloidal speed reducer is a mechanism for reducing the speed of an input shaft by a certain ratio. Cycloidal speed reducers are capable of relatively high ratios in compact sizes with very low backlash. [1] The input shaft drives an eccentric bearing that in turn drives the cycloidal disc in ...
Through work I recently attended a tour of a Sumitomo assembly facility in Surrey, BC, Canada, and recalled seeing the discussion on this page. I asked the Sumitomo rep if cycloidal drives are back-drivable. He conferred with the shop supervisor, and they agreed that their cycloidal drives are back-drivable if the reduction ratio is less than 60.
In addition, there are "cycloidal drive" gears with a gear ratio similar to planetary drives, also called "epicyclic" or "eccentric" gears. Magnetic gears advantages: Leak proof mechanical coupling; Shear / overload proof mechanical coupling; Wear is limited to bearings, not mating contact surfaces of gears
SPOILER ALERT: This article contains major plot details from the finale of Edward Berger’s “Conclave.” Megyn Kelly took to X to criticize Edward Berger’s “Conclave” as a “disgusting ...
A magnetohydrodynamic drive or MHD propulsor is a method for propelling seagoing vessels using only electric and magnetic fields with no moving parts, using magnetohydrodynamics. The working principle involves electrification of the propellant (gas or water) which can then be directed by a magnetic field, pushing the vehicle in the opposite ...
With five multicolor play shapes, this foam fort building set will give kiddos plenty of ways to play. From a cozy couch to a castle and moat, their imagination is the limit.
Harmonic Drive SE strain wave gear set consisting of wave generator bearing (top left), flexspline cup (top right) and circular spline ring (bottom). Strain wave gearing (also known as harmonic gearing ) is a type of mechanical gear system that uses a flexible spline with external teeth, which is deformed by a rotating elliptical plug to engage ...
