Wheel drive and slewing drive solutions
Boosting mobile planetary gear unit performance
Mobile planetary gear systems must provide reliable effectiveness under extremely harsh conditions. In steering wheel drives, this means heavy radial loads, shock loads and tilting activities – all in a limited available space. In slewing machines, coping with the heavy radial loads transmitted to the slewing equipment 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 contact ball bearings, CARB toroidal roller bearings and off-highway hub devices (flanged and geared).
Slewing drives – Intended 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 working challenges, Ever-Power can help you meet them. Working together with Ever-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 level of worm gear pair and 2 nd, 3 rd stage was created with planetary
Ever-Power industrial, yaw and pitch and mobile phone slew drives are designed to function seamlessly in applications requiring slew bearings or racks, perhaps in a large-capacity winch.
Ever-Electric power slewing drives are an essential component in keeping fat and size to a minimum on devices such as for example 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-Ability slewing drives are well suited for the most severe duties in every environment. The look of the planetary systems optimises torque overall performance and radial load ability, in order to give excellent meshing between pinion and band gear.
For accurate adjustment, a few versions have eccentric installation between your pinion axis and the casing axis. Their wide selection of ratios enables selecting motor size and type which best suits the customer’s.
This wide variety 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 turbines and as steering travel on ship propulsion systems, they can be utilised in all applications where accurate positioning is necesary. These Ever-Electric power slewing drives are ideal for the most extreme duties in every environment. The design of the planetary products optimizes torque effectiveness and radial load capability, so as to give ideal meshing between pinion and ring gear. For exact adjustment, some versions have eccentric mounting between your pinion axis and the casing axis. Their wide range of ratios enables selecting motor size and type which greatest satisfies the customer’s requirements and software.

Description
Slewing gear drives are used to put driven machines. They have already been tried and analyzed in many different applications, such as cranes, excavators, and drilling systems. Ever-Power gear units for slewing equipment drives have a modular design. They may be combined with a long or short lantern equipment drive on the productivity side. The mounted outcome pinions are manufactured according to the customer’s specifications. On the input part, we offer solutions for both electrical motors and high-quickness or low-quickness hydraulic motors, a few of which already are standardized.
One frequently requested alternate, particularly as a gear unit for slewing equipment drives in bucket wheel excavators, consists of a Ever-Power planetary gear device with a bevel or perhaps bevel helical gear product on the input area. The drive electric motor and a brake are organized on a bracket on the gear unit, so that the machine no longer should be aligned on site. A brake is certainly always mounted between your motor and the gear unit so that you can resolve the boom in a precise position. An overload protection mechanism can also be provided to safeguard the boom and the drive against inadmissibly large loads.

Slew Drives, commonly known as a Slewing Gear or Slew Bearings, is usually a complete, ready to install system that involves a ball or roller slewing band bearing, drive teach, and completely enclosed housing. It can be custom-made with hydraulic or electric motors, brakes, planetary gearboxes, corrosion protection, along with many other options.
Ever-Power reduce costs by replacing complicated in-house systems in equipment that rotate major loads and require operation and innovation. Each comes with an unlimited slewing position and range, move easily and jolt-totally free, no slip-stick result, and provide the most efficient transmission of high ability and torque conceivable. Our Slew Drives are totally enclosed and sealed casing 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 transportation, forestry equipment sectors, solar trackers, and many more.

Ever-Power slewing drives are an essential component in keeping pounds and size to a minimum on products such as for example tower cranes, Pitch and Yaw drives for wind energy, aerial systems and mixers. Their planetary structure means that they can tolerate very high torque values while maintaining reduced Planetary Slew Drive measurements, reduced weight and high efficiency. The broad range of available ratios enables selecting a motor size and type which greatest accommodates users requirements: hydraulic or electronic. Bevel type and hydraulic brake are some of the options, which are available for this series. Simple mounting, operating reliability and adaptability make these units well suited for the most severe duties and environments.
Customizable drive solutions, most from one source
Our durable, powerful and flexible industrial gear unit solutions satisfy your desires in every respect – the power rating along with the installation. We provide all the important elements of a slewing gear drive under one roofing:
Motor and motor scoop
Brake between the motor and gear device with torque limiter to prevent excessive loads
Protective covers
Primary gear device (helical or bevel-helical)
Planetary gear unit with pinion shaft and extended housing at the output
Output pinion
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 present the right combination of gear systems for every requirement:
Our P series industrial planetary gear devices and the X series industrial bevel gear and bevel-helical gear units are sufficient for smaller torques of up to 500 kNm. A combo of XP series industrial planetary gear products and X series professional bevel-helical gear products 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 at the top and the pinion on the bottom. However, our drive solution is also offered as a bottom-mounting release or “bottom-up” version – in this case the pinion is put on top. The lubrication, oil growth container and the seals will be adapted to the installation position.
This wide selection of Ever-Power planetary gear units is particularly made for pinion and slewing ring drives. Successfully employed on tower cranes, shipboard and harbor cranes, wind generators and as steering travel on ship propulsion systems, they can be used in all applications where exact positioning is necesary. These Ever-Electric power slewing drives are well suited for the most severe duties in every environment. The look of the planetary models optimizes torque efficiency and radial load potential, to be able to give ideal meshing between pinion and band gear. For appropriate 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 client?s requirements and application.
