Wheel drive and slewing drive solutions
Boosting cellular planetary gear unit performance
Mobile planetary gear Planetary Slew Drives devices must provide reliable performance under extremely harsh conditions. In wheel drives, this means weighty radial loads, shock loads and tilting motions – all in a restricted readily available space. In slewing equipment, coping with the hefty radial loads transmitted to the slewing equipment is the challenge.
Advanced bearing plans from Ever-Power can handle these conditions and more. Solutions include:
Wheel drives – Ever-Power offers thin-section tapered roller bearings, thin section angular contact ball bearings, CARB toroidal roller bearings and off-highway hub devices (flanged and geared).
Slewing drives – Designed for the outcome 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-Power, you can accommodate increased external load, improved 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 is designed with planetary
Ever-Electric power industrial, yaw and pitch and portable slew drives are designed to job seamlessly in applications requiring slew bearings or racks, perhaps in a large-capacity winch.
Ever-Electricity slewing drives are an essential component in keeping pounds and size to a minimum on gear such as tower cranes, aerial platforms, discharge booms, excavation and construction equipment.
Their planetary structure allows them to withstand high torque values while maintaining reduced dimensions, decreased weight and high efficiency. The Dana Ever-Electricity slewing drives are suited to the most extreme duties in every environment. The design of the planetary devices optimises torque efficiency and radial load ability, in order to give perfect meshing between pinion and band gear.
For accurate adjustment, several versions have eccentric mounting between the pinion axis and the casing axis. Their broad range of ratios enables selecting electric motor size and type which greatest suits the customer’s.
This wide range of Ever-Power planetary gear units is specifically designed for pinion and slewing ring drives. Successfully employed on tower cranes, shipboard and harbor cranes, wind generators and as steering drive on ship propulsion devices, they can be used in all applications where correct positioning is called for. These Ever-Electrical power slewing drives are suitable for the most serious duties in every environment. The look of the planetary products optimizes torque overall performance and radial load capacity, so as to give ideal meshing between pinion and ring gear. For correct adjustment, some editions have eccentric mounting between the pinion axis and the casing axis. Their wide range of ratios enables the selection of engine size and type which ideal satisfies the customer’s requirements and program.

Description
Slewing equipment drives are used to position driven machines. They have been tried and examined in many distinct applications, such as for example cranes, excavators, and drilling systems. Ever-Power gear products for slewing equipment drives possess a modular design. They can be combined with a long or short lantern gear drive on the productivity side. The mounted productivity pinions are manufactured according to the customer’s requirements. On the input side, you can expect solutions for both electrical motors and high-acceleration or low-swiftness hydraulic motors, some of which are already standardized.
One frequently requested alternative, particularly as a equipment unit for slewing equipment drives in bucket wheel excavators, contains a Ever-Power planetary equipment device with a bevel or bevel helical gear unit on the input part. The drive electric motor and a brake will be arranged on a bracket on the gear device, so that the machine no longer must be aligned on web page. A brake is definitely always mounted between the motor and the apparatus unit as a way to repair the boom in a precise position. An overload safe practices 
mechanism can also be provided to safeguard the boom and the travel against inadmissibly excessive loads.

Slew Drives, commonly known as a Slewing Gear or Slew Bearings, is usually a complete, ready to install system that includes a ball or roller slewing ring bearing, drive educate, and completely enclosed housing. It can be customized with hydraulic or electric motors, brakes, planetary gearboxes, corrosion protection, in addition to many other options.
Ever-Power reduce costs by replacing sophisticated in-house systems in machines that rotate hefty loads and require functionality and innovation. Each has an unlimited slewing angle and range, move smoothly and jolt-totally free, no slip-stick result, and provide the most effective transmission of high vitality and torque practical. Our Slew Drives will be completely 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, security technology, public transport, forestry equipment sectors, solar trackers, and many more.

Ever-Electricity slewing drives are an important component in keeping weight and size to the very least on apparatus such as for example tower cranes, Pitch and Yaw drives for wind energy, aerial platforms and mixers. Their planetary framework signifies that they can tolerate very high torque values while maintaining reduced dimensions, reduced weight and substantial efficiency. The wide selection of available ratios enables the selection of a motor size and type which greatest satisfies users requirements: hydraulic or electric power. Bevel insight and hydraulic brake will be some of the alternatives, which are available for this series. Basic mounting, operating dependability and flexibility make these units suitable for the most severe duties and environments.
Customizable drive solutions, all from one source
Our durable, powerful and flexible industrial gear unit solutions meet your requirements in all respects – the energy rating in addition to the installation. We offer all the important pieces of a slewing equipment drive under one roof:
Motor and motor scoop
Brake between the motor and gear unit with torque limiter to prevent excessive loads
Protective covers
Primary gear device (helical or bevel-helical)
Planetary gear product 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 comprised of various gear units that impact on the same girth gear with internal or external teeth. We give the right combo of gear models for every requirement:
Our P series commercial planetary gear products and the X series industrial bevel equipment and bevel-helical gear models are enough for smaller torques of up to 500 kNm. A blend of XP series industrial planetary gear models and X series industrial bevel-helical gear devices provide larger torques of up to 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 underneath. However, our drive solution is also obtainable as a bottom-mounting variation or “bottom-up” version – in this instance the pinion is put on top. The lubrication, oil expansion container and the seals will be adapted to the mounting position.
This wide variety of Ever-Power planetary gear units is especially suitable for pinion and slewing ring drives. Efficiently used on tower cranes, shipboard and harbor cranes, wind generators and as steering drive on ship propulsion systems, they can be utilized in all applications where accurate positioning is called for. These Ever-Electricity slewing drives are suitable for the most severe duties in every environment. The design of the planetary models optimizes torque performance and radial load ability, in order to give excellent meshing between pinion and band gear. For correct adjustment, some versions have eccentric installation between the pinion axis and the casing axis. Their wide range of ratios enables the selection of engine size and type which greatest suits the customer?s requirements and application. Ever-Power is proud of its quality assurance coverage, including the Type Acceptance Certificate from DNV.
