Planetary Slew Drive

Wheel travel and slewing drive solutions
Boosting mobile planetary gear unit performance
Mobile planetary gear units must provide reliable effectiveness under extremely harsh conditions. In steering wheel drives, this means hefty radial loads, shock loads and tilting movements – all in a limited obtainable space. In slewing machines, coping with the large radial loads transmitted to the slewing gear is the challenge.
Advanced bearing arrangements from Ever-Power are designed for these conditions and more. Solutions include:
Wheel drives – Ever-Power presents thin-section tapered roller bearings, thin section angular contact ball bearings, CARB toroidal roller bearings and off-highway hub systems (flanged and geared).
Slewing drives – Intended for the productivity pinion in slewing drives, Ever-Power provides Explorer tapered roller bearings, spherical roller bearings and cylindrical roller bearings.
Whatever your drive type and operating challenges, Ever-Power can help you meet them. Working together with Ever-Electrical power, you can support increased external load, elevated torque and more compact and lighter arrangements.the worm planetary gearbox is of horizontally input shaft and vertical output shaft type wall-mounted gearbox comprising of three-stage reductions viz. 1 st level of worm gear match and 2 nd, 3 rd stage was created with planetary
Ever-Electric power industrial, yaw and pitch and mobile phone slew drives are designed to function seamlessly in applications requiring slew bearings or perhaps racks, perhaps in a large-capacity winch.
Ever-Ability slewing drives are an important component in keeping weight and size to a minimum on equipment such as tower cranes, aerial platforms, discharge booms, excavation and engineering equipment.
Their planetary structure allows them to withstand high torque values while maintaining reduced dimensions, decreased weight and high efficiency. The Dana Ever-Vitality slewing drives are well suited for the most severe duties in every environment. The design of the planetary systems optimises torque efficiency and radial load potential, so as to give best meshing between pinion and ring gear.
For accurate adjustment, a lot of versions have eccentric mounting between the pinion axis and the casing axis. Their broad range of ratios enables the selection of engine size and type which best suits the customer’s.
This wide range of Ever-Power planetary gear units is especially suitable for pinion and slewing ring drives. Effectively used on tower cranes, shipboard and harbor cranes, wind turbines and as steering drive on ship propulsion devices, they can be utilized in every applications where accurate positioning is called for. These Ever-Power slewing drives are suitable for the most extreme duties in every environment. The design of the planetary products optimizes torque overall performance and radial load ability, as a way to give best meshing between pinion and band gear. For accurate adjustment, some variations have eccentric installation between your pinion axis and the casing axis. Their broad range of ratios enables the selection of electric motor size and type which finest accommodates the customer’s requirements and program.

Ever-Power Gear Systems for Slewing Gears
Technical data
Slewing gear drives are used to position driven devices. They have been tried and examined in many different applications, such as cranes, excavators, and drilling platforms. Ever-Power gear products for slewing gear drives possess a Planetary Slew Drive modular design. They could be combined with a long or short lantern gear drive on the result side. The mounted outcome pinions are manufactured according to the customer’s features. On the input aspect, we offer solutions for both electric motors and high-swiftness or low-rate hydraulic motors, some of which already are standardized.
One frequently requested choice, particularly as a gear unit for slewing gear drives in bucket wheel excavators, consists of a Ever-Power planetary equipment device with a bevel or perhaps bevel helical gear unit on the input part. The drive motor and a brake will be arranged on a bracket on the gear product, so that the system no longer must be aligned on site. A brake can be always mounted between your motor and the gear unit so as to correct the boom in a defined position. An overload safeness mechanism can additionally be provided to protect the boom and the travel against inadmissibly huge loads.

Slew Drives, commonly referred to as a Slewing Gear or Slew Bearings, is usually a complete, ready to install system that contains a ball or roller slewing band bearing, drive educate, and completely enclosed casing. It can be customized with hydraulic or electric motors, brakes, planetary gearboxes, corrosion protection, and also many other options.
Ever-Power lower costs by replacing intricate in-house systems in devices that rotate major loads and require efficiency and innovation. Each comes with an unlimited slewing position and range, move smoothly and jolt-free, no slip-stick result, and provide the most effective transmission of high electrical power and torque conceivable. Our Slew Drives are entirely enclosed and sealed casing withstands harsh environments and increases safety.
As a ready-for-installation program module, they replace countless individual parts. Slew drives are used for aerial platforms, defense technology, public transport, forestry equipment sectors, solar trackers, and much more.

Ever-Electric power slewing drives are an essential component in keeping fat and size to a minimum on equipment such as for example tower cranes, Pitch and Yaw drives for wind energy, aerial systems and mixers. Their planetary framework signifies that they can tolerate very high torque ideals while maintaining reduced sizes, reduced weight and huge efficiency. The broad range of available ratios enables selecting a engine size and type which ideal meets users requirements: hydraulic or electrical. Bevel source and hydraulic brake happen to be some of the options, which are for sale to this series. Straightforward mounting, operating reliability and versatility make these units well suited for the most severe duties and environments.
Customizable drive solutions, most from one source
Our durable, powerful and flexible commercial gear unit solutions meet your requirements in every respect – the power rating as well as the installation. We provide all the important components of a slewing gear drive under one roofing:
Motor and motor scoop
Brake between the motor and gear product with torque limiter to prevent excessive loads
Protective covers
Primary gear product (helical or bevel-helical)
Planetary gear unit with pinion shaft and expanded housing at the output
Output pinion
Slewing gear drives for any power rating and mounting position
For larger devices, the slewing gear drive can be made up of various equipment units that impact on the same girth gear with internal or external teeth. We give the right combo of gear systems for every requirement:
Our P series commercial planetary gear devices and the X series industrial bevel gear and bevel-helical gear devices are enough for smaller torques as high as 500 kNm. A combination of XP series industrial planetary gear units and X series industrial bevel-helical gear units provide larger torques as high as 4,000 kNm.
Slewing equipment drives are generally shaft-mounted designs. This implies that the apparatus unit is mounted at the top and the pinion on the bottom. However, our drive solution is also available as a bottom-mounting release or “bottom-up” version – in this instance the pinion is put at the top. The lubrication, oil growth tank and the seals happen to be adapted to the mounting position.
