Combination Gearboxes

High Power Bevel-Helical-Planetary Solutions

High Power Bevel-Helical-Planetary SolutionsBrevini High Power gear units are designed for medium and high power industrial applications. This model combines the innovative technology and performance of Brevini´s latest S series range with the high quality and reliability of PIV Drives´ Posired series of right-angle gearboxes. The result is a new series of right-angle gear units which have all the benefits of versatile output configurations typical of planetary gear units, as well as the tested input safety of high quality right-angle gearboxes. This solution is more efficient, quieter, more compact and offers a better price / performance ratio compared to ordinary gear units.

The application range of these Brevini Power Transmission gear units includes a variety of reduction ratios − from 1:75 to 1:660 − and a transmission capacity of from 180 hp up to 1,270 hp of power.


Ultra Compact Shaft-Mounted Gear Units-Posiplan

Ultra Compact Shaft-Mounted Gear Units-PosiplanPosiplan models are our newest models whose innovation is protected by a patent. Posiplans feature a combination of planetary and helical/bevel helical gears, thus taking advantage of the strengths of each technology: compact size, reliability and easy maintenance.

This new series of lighter, more compact gear reducers surpass traditional solutions for planetary and bevel helical gear reducers and also ensure shorter production times and lower production costs.

The design of these ultra-compact gear units is based upon precise analyses using FEM (Finite Elements Method) techniques in combination with 3D models. The performance was then confirmed and optimized with field trials. The result is better performance, longer duration and quiet operation.

Advanced engineering techniques, years of experience and the use of high quality parts led to the creation of a product that ensures high performance over time.


Features include:

  • 10 harmonically developed sizes, from 26,500 to 238,800 in-lb of nominal torque.
  • In the planetary helical version, current has up to 4 reduction stages and for reduction ratios of up to i = 2,000:1.
  • In the bevel planetary helical version, currently has up to 4 reduction stages and transmission ratios of up to i = 1,100.
  • Special seals (labyrinth seals or double seals with separate grease-filled chamber) that protect against lubricant leakage and contamination.
  • Output hollow shafts: cylindrical with keyway, cylindrical hollow shaft for shrink disc, and splined shaft.
  • Input motor adaptors for NEMA, IEC and hydraulic motors.
  • Available with flexible and fluid couplings, clutches and torque limiters, and belt couplings.
  • Accessories such as torque arms, shrink discs, backstops and brakes, oil filtering and cooling systems, are also available.
  • The range is being expanded to include 8 more sizes for output torques of up to 590,500 in-lb.
