Wheel travel and slewing drive solutions
Boosting mobile planetary gear unit performance
Mobile planetary gear units must provide reliable performance under extremely harsh conditions. In steering wheel drives, this means serious radial loads, shock loads and tilting activities – all in a limited offered space. In slewing equipment, coping with the heavy 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 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 provides 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 together with Ever-Electrical 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-mounted gearbox comprising of three-stage reductions viz. 1 st stage of worm gear couple and 2 nd, 3 rd stage is designed with planetary
Ever-Electricity industrial, yaw and pitch and mobile slew drives are made to do the job seamlessly in applications requiring slew bearings or racks, perhaps in a large-capacity winch.
Ever-Vitality slewing drives are an essential component in keeping weight and size to a minimum on equipment such as tower cranes, aerial platforms, 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-Vitality slewing drives are ideal for the most serious duties in every environment. The look of the planetary units optimises torque effectiveness and radial load ability, so as to give perfect meshing between pinion and ring gear.
For accurate adjustment, several versions have eccentric installation between your 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 wide range of Ever-Power planetary gear units is especially designed for pinion and slewing ring drives. Successfully used on tower cranes, shipboard and harbor cranes, wind generators and as steering drive on ship propulsion systems, they can be used in all applications where accurate positioning is necesary. These Ever-Power slewing drives are suited to the most serious duties in every environment. The design of the planetary devices optimizes torque overall performance and radial load capacity, to be able to give best meshing between pinion and ring gear. For accurate adjustment, some variants have eccentric installation between your pinion axis and the casing axis. Their wide selection of ratios enables selecting engine size and type which very best matches the customer’s requirements and request.

Ever-Power Gear Units for Slewing Gears
Slewing gear drives are used to position driven devices. They have already been tried and examined in many unique applications, such as for example cranes, excavators, and drilling systems. Ever-Power gear systems for slewing gear drives have a modular design. They might be combined with an extended or short lantern equipment drive on the result side. The mounted output pinions are manufactured based on the customer’s features. On the input aspect, you can expect solutions for both electric motors and high-speed or low-quickness hydraulic motors, a few of which are already standardized.
One frequently requested alternate, particularly as a gear unit for slewing equipment drives in bucket wheel excavators, includes a Ever-Power planetary gear unit with a bevel or perhaps bevel helical gear device on the input side. The drive engine 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 can be always mounted between the motor and the apparatus unit so as to repair the boom in a precise position. An overload safeness mechanism can also be provided to safeguard the boom and the drive 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 consists of a ball or roller slewing ring bearing, drive teach, and completely enclosed housing. It can be personalized with hydraulic or electrical motors, brakes, planetary gearboxes, corrosion protection, and also many other options.
Ever-Power reduce costs by replacing sophisticated in-house systems in machines that rotate weighty loads and require functionality and innovation. Each comes with an unlimited slewing position and range, move effortlessly and jolt-totally free, no slip-stick result, and provide the most effective transmission of high electric power and torque likely. Our Slew Drives are completely enclosed and sealed housing withstands harsh conditions and increases safety.
As a ready-for-installation program module, they replace many individual parts. Slew drives are used for aerial platforms, defense technology, Planetary Slew Drive public transportation, forestry machine sectors, solar trackers, and many more.

Customizable drive solutions, most from one source
Our durable, powerful and flexible professional gear unit solutions satisfy your desires in every respect – the energy rating plus the installation. We provide all the important components of a slewing gear drive under one roofing:
Motor and motor scoop
Brake between the motor and gear product with torque limiter to avoid excessive loads
Primary gear unit (helical or bevel-helical)
Planetary gear product with pinion shaft and extended housing at the output
Slewing gear drives for just about any power rating and mounting position
For larger machines, the slewing gear drive can be made up of various gear units that effect on the same girth equipment with internal or external teeth. We offer the right blend of gear units for every requirement:
Our P series commercial planetary gear units and the X series commercial bevel equipment and bevel-helical gear devices are satisfactory for smaller torques of up to 500 kNm. A combination of XP series commercial planetary gear units and X series commercial bevel-helical gear units provide larger torques of up to 4,000 kNm.
Slewing equipment drives are generally 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 offered as a bottom-mounting version or “bottom-up” version – in cases like this the pinion is put at the top. The lubrication, oil expansion tank and the seals happen to be adapted to the installation position.
