1 3/H Combined gearboxes

2 2 Combined gearboxes - specifications s 3/H gearboxes combine the high technology, performance and efficiency of planetary gearboxes with the robustness, quality and reliability of bevel helical gearboxes. These planetary/bevel helical combination gearboxes deliver the high transmissible torque of our 300 Series along with the excellent power transmission characteristics of our HDO Series and are ideal for applications that demand high power density along with medium-low output speeds. The 3/H range consists of 10 standard catalogue sizes that can transmit up to 1200 knm of torque. Custom combinations are also available to order. A wide choice of gear ratios and above all the availability of numerous intermediate sizes enables the 3/H range to offer a truly complete answer to the needs of target applications. Compared to conventional gearboxes, the flexibility and synergy of 3/H combination gearboxes guarantees significant benefits in terms of: Torque range Thermal capacity Compactness Silent running Versatility in solutions and accessories Output speed Output torque

3 3 Fields of application 3/H combined gearboxes are specially designed for use in high power applications in industries like mining, metal, paper and sugar. Mining industry Metal industry Sugar industry Paper industry

4 4 Product overview Product range Numerous combinations cover a wide range of applications and offer: Gear ratios from 1:100 to 1:1000 Rated power up to 980 kw Reference torque up to 1200 knm M 2REF /HDO 15 3/HDO 16 3/HDO 17 3/HDO 18 3/HDO 19 3/HDO 21 3/HDO 23 3/HDO 25 SIZES AND GEAR RATIOS 3/HDO 21 L Gear ratio Version Size Series

5 5 Variants Output versions solid cylindrical shaft solid shaft with keyway solid shaft with supporting feet solid shaft with keyway and supporting feet hollow shaft with shrink disc hollow shaft with keyway Input versions Single sided cylindrical shaft Cylindrical through shaft Flange with motor coupling bell and intermediary elastic joint between the cylindrical shafts of the motor and gearbox. Mounting position Horizontal input shaft Vertical input shaft Shaft arrangement Depending on the needs of the application, 3/HDO combination gearboxes can be supplied with output shafts on the left or right side.

6 6 Options - Accessories Auxiliary thermal devices The heat dissipation of 3/HDO combination gearboxes can be improved by the addition of devices like: cooling fans keyed on to the shaft integrated cooling circuit with heat exchange coil autonomous cooling units electrical heating elements if very low ambient temperatures make it necessary to pre-heat the lubricant in the casing before start-up and/or during operation. Forced lubrication Standard lubrication is based on a splash system, but forced lubrication can be provided for use in special applications based on: forced lubrication circuits with mechanically driven pumps keyed on to the intermediate shaft of the bevel-helical unit (typical solution for continuous duty) forced lubrication circuits with independently powered pumps (typical solution per intermittent duty) Backstop device The backstop device ensures that the gearbox only turns in one direction, and prevents reverse movement caused by the load connected to the output shaft. Torque arm A torque arm is essential in all shaft mounted applications. The catalogue contains a wide range of standard torque arms for use with combination gearboxes. Certification The following documents are available: Declaration of conformity Test certificate

7 7 Special solutions Special, complete and custom power transmission solutions are available for specific applications involving: Torque arms The design of this accessory generally depends on the customer s machine. In addition to a standard offering, can also supply made to measure torque arms for specific applications. Base plates Depending on the weight of the motor and/or the number of accessories needed for the combination gearbox, it may prove necessary to install a base plate. Base plate configuration depends on the overall weight of the assembled gearbox, motor and accessories. Fluid couplings Fluid couplings are available in different versions and with different options. They are particularly useful in applications involving the acceleration of high inertia loads and/or a large number of starts per hour. Shoe brakes Other accessories A wide range of other accessories is available to satisfy customer and application needs. Options include paint coatings for different kinds of corrosive environment, special seals and motor flanges with integrated fans.
