Wheel drive and slewing drive solutions
Boosting mobile planetary gear unit performance
Mobile planetary gear units must provide reliable efficiency under extremely harsh conditions. In wheel drives, this means large radial loads, shock loads and tilting moves – all in a limited obtainable space. In slewing machines, coping with the serious radial loads transmitted to the slewing gear is the challenge.
Advanced bearing plans from Ever-Power can handle 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 – For the end result 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 with Ever-Electric power, you can support increased external load, increased torque and smaller sized and lighter plans.the worm planetary gearbox is of horizontally input shaft and vertical output shaft type wall-attached gearbox comprising of three-stage reductions viz. 1 st stage of worm gear pair and 2 nd, 3 rd stage is designed with planetary
Ever-Ability industrial, yaw and pitch and cell slew drives are designed to function seamlessly in applications requiring slew bearings or racks, perhaps in a large-capacity winch.
Ever-Ability slewing drives are an important component in keeping excess weight and size to the very least on equipment such as for example tower cranes, aerial systems, discharge booms, excavation and building equipment.
Their planetary structure allows them to withstand high torque values while maintaining decreased dimensions, decreased weight and high efficiency. The Dana Ever-Electricity slewing drives are ideal for the most severe duties in every environment. The look of the planetary units optimises torque performance and radial load capability, 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 very best suits the customer’s.
This wide variety of Ever-Power planetary gear units is particularly suitable for pinion and slewing ring drives. Efficiently used on tower cranes, shipboard and harbor cranes, wind turbines and as steering drive on ship propulsion systems, they works extremely well in all applications where accurate positioning is necesary. These Ever-Electrical power slewing drives are suited to the most severe duties in every environment. The look of the planetary models optimizes torque functionality and radial load capability, so that you can give excellent meshing between pinion and ring gear. For exact adjustment, some versions have eccentric installation between your pinion axis and the casing axis. Their wide range of ratios enables the selection of electric motor size and type which best satisfies the customer’s requirements and application.

Description
Slewing equipment drives are used to position driven machines. They have been tried and tested in many unique applications, such as for example cranes, Planetary Slew Drives Excavators, and drilling systems. Ever-Power gear systems for slewing equipment drives have a modular design. They may be combined with an extended or short lantern gear drive on the end result side. The mounted end result pinions are manufactured in line with the customer’s features. On the input area, you can expect solutions for both electric motors and high-acceleration or low-rate hydraulic motors, some of which already are standardized.
One frequently requested choice, particularly as a gear unit for slewing equipment drives in bucket wheel excavators, involves a Ever-Power planetary gear unit with a bevel or perhaps bevel helical gear product on the input part. The drive engine and a brake happen to be arranged on a bracket on the gear product, so that the system no longer should be aligned on internet site. A brake is certainly always mounted between the motor and the apparatus unit so that you can correct the boom in a defined position. An overload safe practices mechanism can additionally be provided to safeguard the boom and the drive against inadmissibly large loads.

Slew Drives, commonly known as a Slewing Equipment or Slew Bearings, is a complete, prepared to install system that involves a ball or roller slewing band bearing, drive teach, and completely enclosed casing. It can be custom-made with hydraulic or electric motors, brakes, planetary gearboxes, corrosion protection, together with many other options.
Ever-Power lower costs by replacing sophisticated in-house systems in machines that rotate major loads and require features and innovation. Each has an unlimited slewing angle and range, move effortlessly and jolt-free, no slip-stick effect, and provide the most effective transmission of high power and torque feasible. Our Slew Drives are entirely enclosed and sealed casing withstands harsh conditions and increases safety.
As a ready-for-installation system module, they replace countless individual parts. Slew drives are used for aerial platforms, defense technology, public transport, forestry machine sectors, solar trackers, and more.

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 gear units that effect on the same girth equipment with external or internal teeth. We provide the right combination of gear devices for every requirement:
Our P series professional planetary gear systems and the X series industrial bevel gear and bevel-helical gear units are enough for smaller torques as high as 500 kNm. A mixture of XP series professional planetary gear units and X series professional bevel-helical gear products provide larger torques of up to 4,000 kNm.
Slewing equipment drives are usually shaft-mounted designs. This ensures 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 edition or “bottom-up” version – in this case the pinion is positioned at the top. The lubrication, oil growth tank and the seals happen to be adapted to the mounting position.
