Planetary Slew Drive

Wheel drive and slewing drive solutions
Boosting mobile planetary gear unit performance
Mobile planetary gear systems must provide reliable effectiveness under extremely harsh circumstances. In wheel drives, this means serious radial loads, shock loads and tilting actions – all in a restricted obtainable space. In slewing equipment, 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 speak to ball bearings, CARB toroidal roller bearings and off-highway hub devices (flanged and geared).
Slewing drives – For the output 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 can help you meet them. Working with Ever-Power, you can accommodate increased external load, increased torque and more compact 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 stage of worm gear set and 2 nd, 3 rd stage was created with planetary
Ever-Vitality industrial, yaw and pitch and portable 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 essential component in keeping fat and size to the very least on gear 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, decreased 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 products optimises torque effectiveness and radial load potential, to be able to give best meshing between pinion and ring gear.
For accurate adjustment, a few versions have eccentric installation between your pinion axis and the Planetary Slew Drive 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 designed 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 band gear. For accurate adjustment, some variations have eccentric mounting between your pinion axis and the casing axis. Their wide variety of ratios enables selecting electric motor size and type which greatest satisfies the customer’s requirements and software.

Description
Slewing gear drives are used to position driven devices. They have been tried and analyzed 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 may be combined with an extended or short lantern equipment drive on the outcome side. The mounted result pinions are manufactured according to the customer’s technical specs. On the input aspect, we offer solutions for both electrical motors and high-quickness or low-quickness hydraulic motors, a few of which are already standardized.
One frequently requested substitute, particularly as a equipment unit for slewing equipment drives in bucket wheel excavators, contains a Ever-Power planetary gear unit with a bevel or bevel helical gear product on the input side. The drive motor and a brake will be organized on a bracket on the apparatus device, so that the machine no longer needs to be aligned on site. A brake is certainly always mounted between the motor and the gear unit so that you can repair the boom in a precise position. An overload safe practices mechanism can on top of that be provided to protect the boom and the travel against inadmissibly high loads.

Slew Drives, commonly known as a Slewing Equipment or Slew Bearings, is a complete, ready to install system that contains 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, together with 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 likely. Our Slew Drives happen to be totally enclosed and sealed casing 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 measurements, reduced weight and great efficiency. The wide range of available ratios enables the selection of a electric motor size and type which finest suits users requirements: hydraulic or electrical. Bevel source and hydraulic brake are some of the choices, which are for sale to this series. Basic mounting, operating reliability and adaptability make these units well suited for the most extreme duties and environments.
Customizable drive solutions, all from one source
Our durable, powerful and flexible professional gear unit solutions satisfy your desires in all respects – the power rating in addition to 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 extended housing at the output
Output pinion
Slewing equipment drives for any power rating and mounting position
For larger equipment, the slewing gear drive can be comprised of various gear units that impact on the same girth equipment with internal or external teeth. We provide the right mixture of gear products for every requirement:
Our P series professional planetary gear products and the X series professional bevel equipment and bevel-helical gear products are adequate for smaller torques of up to 500 kNm. A combo of XP series professional planetary gear models and X series industrial bevel-helical gear devices provide larger torques of up to 4,000 kNm.
Slewing gear drives are usually shaft-mounted designs. This ensures that the apparatus unit is mounted at the top and the pinion on the bottom. However, our drive remedy is also offered as a bottom-mounting variant or “bottom-up” version – in cases like this the pinion is put on top. The lubrication, oil growth tank and the seals will be adapted to the installation position.
This wide selection of Ever-Power planetary gear units is particularly designed for pinion and slewing ring drives. Successfully employed on tower cranes, shipboard and harbor cranes, wind generators and as steering drive on ship propulsion systems, they can be utilised in all applications where exact positioning is necesary. These Ever-Vitality slewing drives are suitable for the most severe duties in every environment. The design of the planetary products optimizes torque effectiveness and radial load potential, so as to give perfect meshing between pinion and ring gear. For exact adjustment, some versions have eccentric mounting between the pinion axis and the casing axis. Their wide selection of ratios enables the selection of motor size and type which best suits the client?s requirements and software. Ever-Power is pleased with its quality assurance insurance plan, including the Type Approval Certificate from DNV.
