Wheel travel and slewing drive solutions
Boosting cellular planetary gear unit performance
Mobile planetary gear products must provide reliable functionality under extremely harsh conditions. In steering wheel drives, this means serious radial loads, shock loads and tilting movements – all in a restricted offered 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 even 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 products (flanged and geared).
Slewing drives – Pertaining to the productivity pinion in slewing drives, Ever-Power presents Explorer tapered roller bearings, spherical roller bearings and cylindrical roller bearings.
Whatever your drive type and working challenges, Ever-Power will help you meet them. Working together with Ever-Ability, you can support increased external load, improved torque and more compact and lighter arrangements.the worm planetary gearbox is of horizontally input shaft and vertical Planetary Slew Drive output shaft type wall-mounted gearbox comprising of three-stage reductions viz. 1 st stage of worm gear match and 2 nd, 3 rd stage is designed with planetary
Ever-Vitality industrial, yaw and pitch and cellular slew drives are created to do the job 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 fat and size to the very least on gear such as for example tower cranes, aerial platforms, discharge booms, excavation and building equipment.
Their planetary structure allows them to withstand very high torque values while maintaining decreased dimensions, lowered weight and high efficiency. The Dana Ever-Ability slewing drives are suitable for the most severe duties in every environment. The look of the planetary devices optimises torque performance and radial load capability, 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 best suits the customer’s.
This broad range of Ever-Power planetary gear units is particularly suitable for pinion and slewing ring drives. Effectively utilized on tower cranes, shipboard and harbor cranes, wind turbines and as steering travel on ship propulsion devices, they can be used in every applications where correct positioning is necesary. These Ever-Electric power slewing drives are suitable for the most severe duties atlanta divorce attorneys environment. The design of the planetary units optimizes torque effectiveness and radial load capacity, to be able to give perfect meshing between pinion and ring gear. For appropriate adjustment, some types have eccentric mounting between the pinion axis and the casing axis.

Description
Slewing gear drives are used to position driven devices. They have been tried and examined in many several applications, such as for example cranes, excavators, and drilling systems. Ever-Power gear systems for slewing gear drives possess a modular design. They may be combined with an extended or short lantern equipment drive on the productivity side. The mounted end result pinions are manufactured in line with the customer’s specifications. On the input part, you can expect solutions for both electrical motors and high-acceleration or low-speed hydraulic motors, some of which are already standardized.
One frequently requested option, particularly as a gear unit for slewing gear drives in bucket wheel excavators, involves a Ever-Power planetary gear device with a bevel or perhaps bevel helical gear product on the input side. The drive motor and a brake will be arranged on a bracket on the apparatus product, so that the machine no longer must be aligned on site. A brake is usually always mounted between your motor and the gear unit to be able to repair the boom in a precise position. An overload safety mechanism can also be provided to protect the boom and the travel against inadmissibly substantial loads.

Slew Drives, commonly known as a Slewing Gear or Slew Bearings, is definitely a complete, prepared to install system that contains a ball or roller slewing band bearing, drive teach, and completely enclosed housing. It can be custom-made with hydraulic or electrical motors, brakes, planetary gearboxes, corrosion protection, along with many other options.
Ever-Power lower costs by replacing sophisticated in-house systems in machines that rotate serious loads and require features and innovation. Each comes with an unlimited slewing position and range, move easily and jolt-totally free, no slip-stick effect, and provide the most efficient transmission of high electric power and torque practical. Our Slew Drives are entirely enclosed and sealed casing withstands harsh conditions 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 transportation, forestry equipment sectors, solar trackers, and much more.

Ever-Electricity slewing drives are an important component in keeping fat and size to the very least on apparatus such as for example tower cranes, Pitch and Yaw drives for wind strength, aerial systems and mixers. Their planetary composition means that they can tolerate very high torque ideals while maintaining reduced measurements, reduced weight and huge efficiency. The wide range of available ratios allows the selection of a motor size and type which best accommodates users requirements: hydraulic or electronic. Bevel input and hydraulic brake will be some of the options, which are for sale to this series.

Customizable drive solutions, most from one source
Our durable, powerful and flexible professional gear unit solutions meet your requirements in all respects – the energy rating in addition to the installation. We offer all the important elements of a slewing equipment drive under one roof:
Motor and motor scoop
Brake between your motor and gear unit with torque limiter to prevent excessive loads
Protective covers
Primary gear product (helical or bevel-helical)
Planetary gear device with pinion shaft and expanded housing at the output
Output pinion
Slewing equipment drives for just about any power score and mounting position
For larger machines, the slewing equipment drive can be made up of various gear units that impact on the same girth gear with internal or external teeth. We offer the right combo of gear models for every requirement:
Our P series professional planetary gear models and the X series professional bevel equipment and bevel-helical gear products are enough for smaller torques as high as 500 kNm. A combo of XP series professional planetary gear models and X series professional bevel-helical gear units provide larger torques of up to 4,000 kNm.
Slewing gear drives are generally shaft-mounted designs. This signifies that the apparatus unit is mounted on top and the pinion on the bottom. However, our drive remedy is also readily available as a bottom-mounting type or “bottom-up” version – in this case the pinion is positioned on top. The lubrication, oil expansion container and the seals will be adapted to the mounting position.
This wide range of Ever-Power planetary gear units is especially suitable for pinion and slewing ring drives. Efficiently employed on tower cranes, shipboard and harbor cranes, wind turbines and as steering travel on ship propulsion devices, they can be utilized in every applications where exact positioning is necesary. These Ever-Vitality slewing drives are suitable for the most extreme duties in every environment. The look of the planetary devices optimizes torque performance and radial load capacity, so that you can give ideal meshing between pinion and ring gear. For appropriate adjustment, some versions have eccentric mounting between the pinion axis and the casing axis. Their wide range of ratios enables selecting engine size and type which best suits the customer?s requirements and app. Ever-Power is proud of its quality assurance insurance plan, including the Type Acceptance Certificate from DNV.
