Planetary Slew Drive

Wheel travel and slewing drive solutions
Boosting mobile planetary gear unit performance
Mobile planetary gear models must provide reliable functionality under extremely harsh conditions. In wheel drives, this means hefty radial loads, shock loads and tilting moves – all in a limited obtainable space. In slewing machines, coping with the major radial loads transmitted to the slewing gear is the challenge.
Advanced bearing plans from Ever-Power can handle these conditions and more. Solutions include:
Wheel drives – Ever-Power presents thin-section tapered roller bearings, thin section angular contact ball bearings, CARB toroidal roller bearings and off-highway hub units (flanged and geared).
Slewing drives – For the outcome 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 with Ever-Electricity, 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-attached 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-Vitality industrial, yaw and pitch and cell slew drives are designed to function seamlessly in applications requiring slew bearings or racks, perhaps in a large-capacity winch.
Ever-Ability slewing drives are an essential component in keeping excess weight and size to the very least on gear such as tower cranes, aerial systems, discharge booms, excavation and structure equipment.
Their planetary structure allows them to withstand high torque values while maintaining decreased dimensions, decreased weight and high efficiency. The Dana Ever-Ability slewing drives are ideal for the most severe duties in every environment. The design of the planetary models optimises torque overall performance and radial load ability, as a way to give best meshing between pinion and band gear.
For accurate adjustment, a lot of versions have eccentric mounting between the pinion axis and the casing axis. Their broad range of ratios enables the selection of engine size and type which very best suits the customer’s.
This wide variety of Ever-Power planetary gear units is particularly suitable for pinion and slewing ring drives. Successfully used on tower cranes, shipboard and harbor cranes, wind turbines and as steering drive on ship propulsion systems, they works extremely well in all applications where accurate positioning is necesary. These Ever-Electrical power slewing drives are suited to the most serious duties in every environment. The look of the planetary devices optimizes torque functionality and radial load ability, so that you can give excellent 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 electric motor size and type which best satisfies the customer’s requirements and application.

Description
Slewing equipment drives are used to position driven machines. They have been tried and tested 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 gear drive on the end result side. The mounted end result pinions are manufactured in line with the customer’s features. On the input area, you can expect solutions for both electric motors and high-acceleration or low-rate hydraulic motors, some of which already are standardized.
One frequently requested solution, particularly as a gear unit for slewing equipment drives in bucket wheel excavators, involves a Ever-Power planetary gear unit with a bevel or perhaps bevel helical gear unit on the input aspect. The drive engine and a brake are arranged on a bracket on the gear product, so that the system no longer should be aligned on internet site. A brake is certainly always mounted between the motor and the apparatus unit so that you can correct the boom in a defined position. An overload safeness mechanism can also be provided to protect the boom and the drive against inadmissibly substantial loads.

Slew Drives, commonly referred to as a Slewing Equipment or Slew Bearings, is a complete, prepared to install system that involves a ball or roller slewing ring bearing, drive teach, and completely enclosed casing. It can be custom-made with hydraulic or electric motors, brakes, planetary gearboxes, corrosion protection, together with many other options.
Ever-Power decrease costs by replacing sophisticated in-house systems in devices that rotate major loads and require efficiency and innovation. Each has an unlimited slewing angle and range, move effortlessly and jolt-free, no slip-stick effect, and provide the most effective transmission of high electrical power and torque Planetary Slew Drives likely. Our Slew Drives are entirely 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 used for aerial platforms, defense technology, public transport, forestry machine sectors, solar trackers, and more.

Customizable drive solutions, almost all from one source
Our durable, powerful and flexible commercial gear unit solutions satisfy your desires in every respect – the power rating as well as the installation. We offer all the important parts of a slewing equipment drive under one roof:
Motor and motor scoop
Brake between the motor and gear product with torque limiter to prevent excessive loads
Protective covers
Primary gear unit (helical or bevel-helical)
Planetary gear unit with pinion shaft and prolonged 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 gear units that effect on the same girth equipment with external or internal teeth. We provide the right combination of gear devices for every requirement:
Our P series professional planetary gear systems and the X series industrial bevel gear and bevel-helical gear units are enough for smaller torques of up to 500 kNm. A mixture of XP series professional planetary gear units 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 ensures that the apparatus unit is mounted on top and the pinion on the bottom. However, our drive remedy is also available as a bottom-mounting edition or “bottom-up” version – in this case the pinion is put at the top. The lubrication, oil growth container and the seals happen to be adapted to the mounting position.
This wide 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 devices, they can be used in all applications where exact positioning is called for. These Ever-Electrical power slewing drives are suited to the most severe duties in every environment.
