Kronenrad Royal® - Balance Drive AG

A Kronenrad Royal® gearbox is an angular gearbox in the classic design, similar to a bevel gear. At first glance, the Kronenrad Royal® geometry looks like a curved rack and is defined by the translation, the pinion geometry and position. In most applications, a shaft angle of 90 ° is, wherein can be varied in a crown gear of the axial angle of 0 ° to 180 °.

An important advantage of the Kronenrad Royal® gear is the axial freedom of the pinion. This means that the contact pattern on the Royal® crown gear is independent of the axial position of the pinion. This facilitates the assembly and construction of the angular gear, since no axial bearing of the pinion is necessary.

Advantages at a glance

High efficiency (similar to a spur gear)
insensitive to temperature changes, because the pinion shaft can be axially
axial freedom of the pinion, Thus, the contact pattern is not influenced by the axial position of pinion
no axial forces on the pinion, thus more compact design for angular drive
Possibility of head bearing of the pinion shaft and thereby higher stiffness and improved vibration damping
high ratios realized in one stage, up to i = 20
Multiple offs realized, d.h. a plurality of pinion can be driven by a crown wheel
represented between 0 ° and 180 °, any shaft angle
large hollow shaft possible
by means of helical gearing can be represented axially offset

“Thanks to their compact design and cost-effective structure, the Kronenrad Royal® differential gears are especially suitable for hybrids- and electric vehicles. "

Due to the compact design and the axial freedom of the pinion, the crown gear set is suitable in actuators in the engine area or for flap adjustment drives using cycloidal gears (Can also be combined as a bevel gear with Royal® crown gears)
