Wheel drive and slewing drive solutions
Boosting cellular planetary gear unit performance
Mobile planetary gear systems must provide reliable effectiveness under extremely harsh circumstances. In steering wheel drives, this means serious radial loads, shock loads and tilting actions – all in a restricted obtainable space. In slewing devices, coping with the hefty radial loads transmitted to the slewing equipment is the challenge.
Advanced bearing plans from Ever-Power are designed for these conditions and even 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 devices (flanged and geared).
Slewing drives – For the outcome pinion in slewing drives, Ever-Power presents Explorer tapered roller bearings, spherical roller bearings and cylindrical roller bearings.
Whatever your drive type and operating challenges, Ever-Power will help you meet them. Working with Ever-Power, you can accommodate increased external load, elevated torque and smaller sized and lighter plans.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 level of worm gear set and 2 nd, 3 rd stage is designed with planetary
Ever-Vitality industrial, yaw and pitch and mobile phone slew drives are created to operate seamlessly in applications requiring slew bearings or perhaps racks, perhaps in a large-capacity winch.
Ever-Electrical power slewing drives are an important component in keeping fat and size to the very least on gear such as tower cranes, aerial systems, discharge booms, excavation and engineering equipment.
Their planetary structure allows them to withstand very high torque values while maintaining reduced dimensions, reduced weight and high efficiency. The Dana Ever-Electric power slewing drives are well suited for the most severe duties in every environment. The design of the planetary devices optimises torque effectiveness and radial load potential, to be able to give ideal meshing between pinion and ring gear.
For accurate adjustment, a few 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 greatest suits the customer’s.
This wide range of Ever-Power planetary gear units is specifically suitable for pinion and slewing ring drives. Efficiently employed on tower cranes, shipboard and harbor cranes, wind turbines and as steering travel on ship propulsion devices, they can be used in all applications where correct positioning is called for. These Ever-Electricity slewing drives are well suited for the most extreme duties in every environment. The design of the planetary units optimizes torque efficiency and radial load capacity, in order to give ideal meshing between pinion and ring gear. For accurate adjustment, some variations have eccentric installation between your pinion axis and the casing axis. Their wide variety of ratios enables the selection of electric motor size and type which greatest meets the customer’s requirements and software.

Description
Slewing gear drives are used to position driven devices. They have been tried and examined in many diverse applications, such as for example cranes, excavators, and drilling systems. Ever-Power gear devices for slewing equipment drives have a modular design. They could be combined with an extended or short lantern equipment drive on the outcome side. The mounted output pinions are manufactured according to the customer’s technical specs. On the input aspect, we offer solutions for both electric motors and high-swiftness or low-quickness hydraulic motors, a few of which are already standardized.
One frequently requested option, particularly as a gear unit for slewing gear drives in bucket wheel excavators, includes a Ever-Power planetary gear unit with a bevel or bevel helical gear device on the input side. The drive motor and a brake will be arranged on a bracket on the gear unit, so that the machine no longer needs to be aligned on web page. A brake is certainly always mounted between the motor and the gear unit so as to repair the boom in a defined position. An overload protection mechanism can on top of that be provided to protect the boom and the drive against inadmissibly high loads.

Slew Drives, commonly known as a Slewing Equipment or Slew Bearings, is a complete, ready to install system that includes a ball or roller slewing band bearing, drive coach, and completely enclosed housing. It can be personalized with hydraulic or electric motors, brakes, planetary gearboxes, corrosion protection, and many other options.
Ever-Power decrease costs by replacing intricate in-house systems in equipment that rotate heavy loads and require features and innovation. Each has an unlimited slewing position and range, move easily and jolt-totally free, no slip-stick impact, and provide the most effective transmission of high electric power and torque feasible. Our Slew Drives will be totally enclosed and sealed housing withstands harsh environments and increases safety.
As a ready-for-installation program module, they replace many individual parts. Slew drives are used for aerial platforms, protection technology, public transport, forestry equipment sectors, solar trackers, and many more.

Ever-Vitality slewing drives are an important component in keeping pounds and size to the very least on apparatus such as for example tower cranes, Pitch and Yaw drives for wind energy, aerial systems and mixers. Their planetary structure implies that they can endure very high torque values while maintaining reduced sizes, reduced weight and great efficiency. The 
wide range of available ratios enables the selection of a engine size and type which finest suits users requirements: hydraulic or electrical. Bevel type and hydraulic brake are some of the choices, which are available for this series. Simple mounting, operating stability and adaptability make these units well suited for the most extreme duties and environments.
Customizable drive solutions, every from one source
Our durable, powerful and flexible professional gear unit solutions satisfy your desires in all respects – the power rating and also the installation. We offer all the important pieces of a slewing equipment drive under one roofing:
Motor and motor scoop
Brake between your motor and gear unit with torque limiter to avoid excessive loads
Protective covers
Primary gear device (helical or bevel-helical)
Planetary gear unit with pinion shaft and expanded housing at the output
Output pinion
Slewing equipment drives for any power score and mounting position
For larger equipment, the slewing gear drive can be comprised of various equipment units that effect on the same girth equipment with internal or external teeth. We present the right mixture of gear devices for every requirement:
Our P series professional planetary gear devices and the X series professional bevel equipment and bevel-helical gear products are adequate for smaller torques as high as 500 kNm. A combo of XP series professional planetary gear units and X series industrial bevel-helical gear devices provide larger torques as high as 4,000 kNm.
Slewing gear drives are generally shaft-mounted designs. This means that the gear unit is mounted at the top and the pinion on the bottom. However, our drive remedy is also available as a bottom-mounting variation or “bottom-up” version – in cases like this the pinion is put on top. The lubrication, oil expansion tank and the seals will be adapted to the installation position.
