Cycloidal drives can feature zero backlash and high torque capacity while being compact in size, unlike Involute gearboxes. They are useful in situations where low speed with high torque is required. Cycloidal drives may be designed with significantly higher contact areas for their size than any gear-based transmission such as epicyclic gearing .

2019年1月14日 · The heart of a cycloidal drive is the cycloidal disc, whose geometry plays a central role in the kinematic of the gearbox. The profile of such a disc can be traced back to a cycloid. That’s why the gearbox is called a cycloidal drive. Since cycloidal drives are used to reduce the speed, they are also referred to as cycloidal speed reducers.

2024年3月13日 · Single-stage cycloidal gearboxes are compact, high-precision devices designed for applications requiring efficient torque transmission and minimal to zero backlash. These gearboxes operate on the principle of a cycloidal disc rotating eccentrically, engaging with pins or rollers to convert input shaft rotation into a slowed output motion.

2018年12月21日 · Since a rolling circle is always used to construct the tooth shape of two gears to be mated, cycloidal gears are always specially matched to each other. A cycloidal gear cannot be replaced easily by a gear with a different number of teeth as is the case with involute gears.

2024年4月16日 · Single-stage cycloidal gearboxes are compact, high-precision devices designed for applications requiring efficient torque transmission and minimal to zero backlash. These gearboxes operate on the principle of a cycloidal disc rotating eccentrically, engaging with pins or rollers to convert input shaft rotation into a slowed output motion.

2019年1月14日 · Such a cycloidal shape is obtained by a rolling circle that rolls on a base circle (see also article “Geometry of cycloidal gears“). The cycloid then corresponds to the path described by a point at the circumference of the rolling circle. The resulting cycloidal shape (ordinary cycloid) is referred to as the reference profile.

2019年11月22日 · A cycloidal gearbox uses the principles of cycloidal gears to provide high gear ratios (often 100:1 or greater) with excellent torsional stiffness, good shock load capacity, stable backlash over the gearbox life, and low wear.

Cycloidal gearing provides a high tilting stiffness due to the number of rolling elements engaged. An eccentric profile on a rotating shaft creates the cycloidal motion that positions the needles in the case. An internal transfer mechanism converts this eccentric movement to rotary.

For the most part, it is arranged into four kinds of the cycloid drives by the flap profile of the cycloid plate outfit and the roller gears movement: the stationary ring gear compose epicycloid reducer, the pivoting ring gear write epicycloid reducer, the stationary ring gear compose hypocycloid reducer and the turning ring gear write hypocyclo...
