What is cycloid reducer?
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.
Are cycloidal drives back drivable?
Cycloidal drives are not, in general, backdrivable.
How does a cycloidal gearbox work?
As the disc rotates, the lobes of the cycloidal disc act like teeth and engage with pins on a stationary ring gear. The cycloidal disc also has roller pins that protrude through the disc, and these pins attach to an output disc which transfers motion to an output shaft.
Does cycloidal drive increase torque?
Planetary and Cycloidal reducers provide mechanical advantage by decreasing speed and increasing output torque.
What is a RV reducer?
RV reducer is a two-stage planetary gear train with cyclic symmetry structure. A dynamic model of RV reducer is established by incorporating bearing stiffness, crankshaft stiffness and mesh stiffness. The central components and an arbitrary number of planetary components are considered.
What is a cycloid curve?
cycloid, the curve generated by a point on the circumference of a circle that rolls along a straight line. If r is the radius of the circle and θ (theta) is the angular displacement of the circle, then the polar equations of the curve are x = r(θ – sin θ) and y = r(1 – cos θ).
How does a Cyclo drive work?
Cyclo Drives are mechanism for reducing the speed of an input shaft by a certain ratio. Cyclo Drives are capable of high ratios in compact sizes. The input shaft drives an eccentric bearing that in turn drives the cycloidal disc in an eccentric, cycloidal motion.
Is cycloidal Backdrivable gearbox?
Figure 1.4 The exploded view of a harmonic drive assembly. The cycloidal mechanism is an ideal solution that allows the design of a highly backdrivable joint that is stable and compact.

Who invented cycloidal gears?
There is some dispute over the invention of cycloidal gears. Those involved include Gérard Desargues, Philippe de La Hire, Ole Rømer, and Charles Étienne Louis Camus.
What is a harmonic drive motor?
Harmonic Drive, also called Harmonic Drive gear, harmonic gear, or strain wave gearing, mechanical speed-changing device, invented in the 1950s, that reduces the gear ratio of a rotary machine to increase torque. It operates on a principle different from that of conventional speed changers.
