Wheel travel and slewing drive solutions
Boosting cellular planetary gear unit performance
Mobile planetary gear units must provide reliable functionality under extremely harsh circumstances. In steering wheel drives, this means major radial loads, shock loads and tilting actions – all in a restricted obtainable space. In slewing machines, coping with the major 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 devices (flanged and geared).
Slewing drives – For the end result pinion in slewing drives, Ever-Power presents Explorer tapered roller bearings, spherical roller bearings and cylindrical roller bearings.
Whatever your drive type and functioning challenges, Ever-Power can help you meet them. Working with Ever-Power, you can support increased external load, increased 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-Power industrial, yaw and pitch and cellular slew drives are created to operate seamlessly in applications requiring slew bearings or racks, perhaps in a large-capacity winch.
Ever-Electrical power slewing drives are an important component in keeping fat and size to a Planetary Slew Drive minimum on products such as tower cranes, aerial systems, discharge booms, excavation and engineering equipment.
Their planetary structure allows them to withstand high torque values while maintaining lowered dimensions, lowered weight and high efficiency. The Dana Ever-Electricity slewing drives are suited to the most extreme duties in every environment. The look of the planetary products optimises torque effectiveness and radial load potential, so that you can give best meshing between pinion and ring gear.
For accurate adjustment, several versions have eccentric mounting between the pinion axis and the casing axis. Their broad range of ratios enables selecting motor size and type which very best suits the customer’s.
This wide selection of Ever-Power planetary gear units is specifically designed for pinion and slewing ring drives. Efficiently utilized on tower cranes, shipboard and harbor cranes, wind turbines and as steering travel on 
ship propulsion systems, they can be utilized in every applications where accurate positioning is called for. These Ever-Power slewing drives are suited to the most extreme duties in every environment. The look of the planetary systems optimizes torque functionality and radial load capacity, in order to give ideal meshing between pinion and ring gear.

Description
Slewing gear drives are used to put driven equipment. They have already been tried and tested in many different applications, such as cranes, excavators, and drilling platforms. Ever-Power gear units for slewing equipment drives possess a modular design. They are often combined with a long or short lantern gear drive on the outcome side. The mounted output pinions are manufactured according to the customer’s specifications. On the input side, we offer solutions for both electric motors and high-acceleration or low-velocity hydraulic motors, some of which are already standardized.
One frequently requested alternate, particularly as a gear unit for slewing gear drives in bucket wheel excavators, includes a Ever-Power planetary equipment unit with a bevel or bevel helical gear product on the input aspect. The drive motor and a brake will be organized on a bracket on the gear product, so that the system no longer should be aligned on web page. A brake is definitely always mounted between the motor and the gear unit in order to repair the boom in a defined position. An overload safe practices mechanism can additionally be provided to safeguard the boom and the travel against inadmissibly great loads.

Slew Drives, commonly referred to as a Slewing Equipment or Slew Bearings, is usually a complete, ready to install system that consists of a ball or roller slewing band bearing, drive train, and completely enclosed housing. It can be personalized with hydraulic or electric motors, brakes, planetary gearboxes, corrosion protection, along with many other options.
Ever-Power decrease costs by replacing sophisticated in-house systems in machines that rotate major loads and require efficiency and innovation. Each has an unlimited slewing angle and range, move easily and jolt-free, no slip-stick impact, and provide the most effective transmission of high vitality and torque feasible. Our Slew Drives will be entirely enclosed and sealed casing withstands harsh conditions and increases safety.
As a ready-for-installation program module, they replace many individual parts. Slew drives are utilized for aerial platforms, defense technology, public transportation, forestry machine sectors, solar trackers, and many more.

Planetary gear unit with pinion shaft and prolonged housing at the output
Output pinion
Slewing equipment drives for just about any power rating and mounting position
For larger equipment, the slewing gear drive can be made up of various gear units that impact on the same girth gear with internal or external teeth. We give the right combo of gear units for every requirement:
Our P series industrial planetary gear models and the X series professional bevel equipment and bevel-helical gear units are adequate for smaller torques as high as 500 kNm. A combo of XP series commercial planetary gear devices and X series industrial bevel-helical gear systems provide larger torques as high as 4,000 kNm.
Slewing equipment drives are usually shaft-mounted designs. This signifies that the apparatus unit is mounted at the top and the pinion on underneath. However, our drive answer is also offered as a bottom-mounting variant or “bottom-up” version – in cases like this the pinion is put at the top. The lubrication, oil growth tank and the seals happen to be adapted to the mounting position.
