Rolls-Royce is pioneering the UltraFan engine family architecture containing a planetary gearbox in a power range of 15 to 80 megawatts. To increase the efficiency of the UltraFan, a planetary gearbox is introduced between fan and intermediate pressure compressor. This enables running the turbine to rotate faster and allows a reduced fan speed.

The load carrying capacity of spur gears may be calculated by ISO 6336 using influence factors. The face load factor considers the impact of the non-uniform load distribution over the face width. Even if the gears had perfect geometry, the load would not distribute uniformly along the contact lines. The face load factor depends on deformations of all parts of the containing gearbox and mainly of the teeth, gears and shafts as well as on manufacturing and assembly deviations.

Transverse magnetic flux motors -- also known as step motors -- become Hybrid Servos when you operate them closed loop. This is the same transformation that happens between running a 3-phase synchronous motor from line voltage as opposed to running it closed loop as a brushless servo. In the case of hybrid motors, there are many degrees of what is advertised as "closed loop," and thus significant differences in the performance improvements seen.

Are you looking for one simple formula to help you choose between centralized and decentralized motor control? Unfortunately, such a formula does not exist. However, evaluating the overall size of the system, comparing labor and material costs, and maintaining flexibility can help guide engineers in the right direction.

When City Scrap & Salvage experienced a catastrophic failure of the driveline between the motor and rotor of its automotive shredder, the company called on Voith Turbo for a potential manufacturing solution.

RBI Solar relies on TB Wood's custom jaw couplings to provide long lasting performance in tough environments.
