Wheel travel and slewing drive solutions
Boosting mobile planetary gear unit performance
Mobile planetary gear models must provide reliable performance under extremely harsh conditions. In steering wheel drives, this means major radial loads, shock loads and tilting motions – all in a limited obtainable space. In slewing equipment, coping with the serious 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 provides thin-section tapered roller bearings, thin section angular get in touch with ball bearings, CARB toroidal roller bearings and off-highway hub models (flanged and geared).
Slewing drives – Designed for the output pinion in slewing drives, Ever-Power offers 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-Ability, you can support increased external load, improved torque and smaller sized and lighter plans.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 stage of worm gear pair and 2 nd, 3 rd stage is designed with planetary
Ever-Electric power industrial, yaw and pitch and portable slew drives are made to function seamlessly in Planetary Slew Drive applications requiring slew bearings or perhaps racks, perhaps in a large-capacity winch.
Ever-Power slewing drives are an essential component in keeping fat and size to a minimum on products such as tower cranes, aerial systems, discharge booms, excavation and construction equipment.
Their planetary structure allows them to withstand high torque values while maintaining lowered dimensions, reduced weight and high efficiency. The Dana Ever-Electric power slewing drives are suited to the most severe duties atlanta divorce attorneys environment. The design of the planetary devices optimises torque effectiveness and radial load capability, so that you can give perfect meshing between pinion and ring gear.
For accurate adjustment, a few versions have eccentric mounting between your pinion axis and the casing axis. Their wide range of ratios enables the selection of engine size and type which finest suits the customer’s.
This wide selection of Ever-Power planetary gear units is especially created 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 works extremely well in every applications where accurate positioning is called for. These Ever-Ability slewing drives are well suited for the most serious duties in every environment. The design of the planetary units optimizes torque performance and radial load capability, so that you can give perfect meshing between pinion and ring gear. For exact adjustment, some versions have eccentric mounting between the pinion axis and the casing axis.

Description
Slewing gear drives are used to position driven devices. They have already been tried and tested in many diverse applications, such as cranes, excavators, and drilling platforms. Ever-Power gear devices for slewing equipment drives possess a modular design. They may be combined with an extended or short lantern gear drive on the productivity side. The mounted result pinions are manufactured based on the customer’s specs. On the input side, we offer solutions for both electric motors and high-rate or low-swiftness hydraulic motors, a few of which already are standardized.
One frequently requested solution, particularly as a equipment unit for slewing equipment drives in bucket wheel excavators, includes a Ever-Power planetary gear product with a bevel or perhaps bevel helical gear product on the input part. The drive motor and a brake will be organized on a bracket on the apparatus device, so that the system no longer needs to be aligned on web page. A brake can be always mounted between the motor and the apparatus unit so as to resolve the boom in a defined position. An overload safety mechanism can additionally be provided to safeguard the boom and the drive against inadmissibly high loads.

Slew Drives, commonly referred to as a Slewing Equipment or Slew Bearings, is a complete, ready to install system that contains a ball or roller slewing ring bearing, drive educate, and completely enclosed housing. It can be customized with hydraulic or electrical motors, brakes, planetary gearboxes, corrosion protection, in addition to many other options.
Ever-Power reduce costs by replacing complicated in-house systems in equipment that rotate serious loads and require functionality and innovation. Each comes with an unlimited slewing angle and range, move smoothly and jolt-free, no slip-stick effect, and provide the most efficient transmission of high electricity and torque possible. Our Slew Drives are entirely enclosed and sealed housing 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 transportation, forestry machine sectors, solar trackers, and many more.

Ever-Ability slewing drives are an essential component in keeping pounds and size to the very least on equipment such as tower cranes, Pitch and Yaw drives for wind strength, aerial systems and mixers. Their planetary framework implies that they can resist very high torque values while maintaining reduced dimensions, reduced weight and huge efficiency. The wide variety of available ratios permits selecting a engine size and type which best meets users requirements: hydraulic or electronic. Bevel type and hydraulic brake are some of the options, which are available for this series. Straightforward mounting, operating dependability and versatility make these units suitable for the most serious duties and environments.
Customizable drive solutions, most from one source
Our durable, powerful and flexible professional gear unit solutions meet your requirements in every respect – the power rating plus the installation. We offer all the important components of a slewing gear drive under one roofing:
Motor and motor scoop
Brake between the motor and gear device with torque limiter to avoid excessive loads
Protective covers
Primary gear device (helical or bevel-helical)
Planetary gear product with pinion shaft and extended housing at the output
Output pinion
Slewing gear drives for any power rating and mounting position
For larger devices, the slewing equipment drive can be made up of various equipment units that effect on the same girth equipment with internal or external teeth. We provide the right combination of gear units for every requirement:
Our P series commercial planetary gear products and the X series commercial bevel gear and bevel-helical gear systems are adequate for smaller torques of up to 500 kNm. A combo of XP series industrial planetary gear models and X series industrial bevel-helical gear systems provide larger torques of up to 4,000 kNm.
Slewing equipment drives are usually shaft-mounted designs. This means that the gear unit is mounted at the top and the pinion on the bottom. However, our drive option is also available as a bottom-mounting type or “bottom-up” version – in cases like this the pinion is positioned at the top. The lubrication, oil expansion tank and the seals will be adapted to the mounting position.
This wide selection of Ever-Power planetary gear units is specifically created for pinion and slewing ring drives. Effectively used on tower cranes, shipboard and harbor cranes, wind turbines and as steering travel on ship propulsion systems, they can be utilized in all applications where exact positioning is called for. These Ever-Vitality slewing drives are suited to the most serious duties in every environment. The design of the planetary products optimizes torque effectiveness and radial load ability, to be able to give perfect meshing between pinion and ring gear. For accurate adjustment, some variations have eccentric installation between the pinion axis and the casing axis. Their wide range of ratios enables selecting motor size and type which best suits the customer?s requirements and application. Ever-Power is proud of its quality assurance policy, including the Type Authorization Certificate from DNV.
