Wheel drive and slewing drive solutions
Boosting mobile planetary gear unit performance
Mobile planetary gear systems must provide reliable performance under extremely harsh circumstances. In steering wheel drives, this means heavy radial loads, shock loads and tilting motions – all in a restricted available space. In slewing devices, coping with the heavy 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 speak to ball bearings, CARB toroidal roller bearings and off-highway hub models (flanged and geared).
Slewing drives – Designed for the end result 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 together with Ever-Electricity, 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-installed 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-Electricity industrial, yaw and pitch and mobile slew drives are designed to operate seamlessly in applications requiring slew bearings or perhaps racks, perhaps in a large-capacity winch.
Ever-Electricity slewing drives are an essential component in keeping weight and size to a minimum on equipment such as tower cranes, aerial systems, discharge booms, excavation and construction equipment.
Their planetary structure allows them to withstand very high torque values while maintaining decreased dimensions, lowered weight and high efficiency. The Dana Ever-Vitality slewing drives are ideal for the most severe duties in every environment. The look of the planetary devices optimises torque performance and radial load ability, so as to give perfect meshing between pinion and band gear.
For accurate Planetary Slew Drive adjustment, a few versions have eccentric mounting between the pinion axis and the casing axis. Their wide variety of ratios enables the selection of motor size and type which best suits the customer’s.
This broad range of Ever-Power planetary gear units is especially created for pinion and slewing ring drives. Effectively utilized on tower cranes, shipboard and harbor cranes, wind generators and as steering travel on ship propulsion systems, they can be utilised in all applications where correct positioning is called for. These Ever-Power slewing drives are suitable for the most serious duties in every environment. The look of the planetary devices optimizes torque functionality and radial load ability, as a way to give excellent meshing between pinion and ring gear. For accurate adjustment, some editions have eccentric installation between your pinion axis and the casing axis. Their wide variety of ratios enables selecting engine size and type which very best matches the customer’s requirements and program.

Description
Slewing gear drives are used to position driven devices. They have been tried and tested in many different applications, such as cranes, excavators, and drilling systems. Ever-Power gear models for slewing gear drives have a modular design. They may be combined with a long or short lantern gear drive on the outcome side. The mounted result pinions are manufactured in line with the customer’s technical specs. On the input aspect, we offer solutions for both electrical motors and high-acceleration or low-rate hydraulic motors, a few of which already are standardized.
One frequently requested alternate, particularly as a gear unit for slewing gear drives in bucket wheel excavators, involves a Ever-Power planetary gear product with a bevel or bevel helical gear device on the input side. The drive engine and a brake are arranged on a bracket on the apparatus device, so that the system no longer must be aligned on web page. A brake can be always mounted between the motor and the gear unit so that you can fix the boom in a precise position. An overload security mechanism can additionally be provided to safeguard the boom and the travel against inadmissibly high loads.

Slew Drives, commonly referred to 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 educate, and completely enclosed housing. It can be personalized with hydraulic or electric motors, brakes, planetary gearboxes, corrosion protection, together with many other options.
Ever-Power reduce costs by replacing intricate in-house systems in machines that rotate hefty loads and require efficiency and innovation. Each comes with an unlimited slewing angle and range, move easily and jolt-totally free, no slip-stick impact, and provide the most efficient transmission of high ability and torque feasible. Our Slew Drives are totally enclosed and sealed housing withstands harsh conditions and increases safety.
As a ready-for-installation system module, they replace many individual parts. Slew drives are utilized for aerial platforms, protection technology, public transport, forestry equipment sectors, solar trackers, and more.

Customizable drive solutions, most from one source
Our durable, powerful and flexible industrial gear unit solutions meet your requirements in all respects – the power rating and also the installation. We provide 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 avoid excessive loads
Protective covers
Primary gear unit (helical or bevel-helical)
Planetary gear product with pinion shaft and prolonged housing at the output
Output pinion
Slewing gear drives for any power ranking and mounting position
For larger devices, the slewing equipment drive can be made up of various gear units that impact on the same girth gear with external or internal teeth. We provide the right combo of gear devices for every requirement:
Our P series commercial planetary gear units and the X series industrial bevel equipment and bevel-helical gear products are enough for smaller torques of up to 500 kNm. A combination of XP series industrial planetary gear units and X series industrial bevel-helical gear systems 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 solution is also readily available as a bottom-mounting variation or “bottom-up” version – in this case the pinion is put at the top. The lubrication, oil expansion container and the seals will be adapted to the mounting position.
