Wheel travel and slewing drive solutions
Boosting cellular planetary gear unit performance
Mobile planetary gear models must provide reliable performance under extremely harsh conditions. In wheel drives, this means weighty radial loads, shock loads and tilting activities – all in a limited available space. In slewing devices, coping with the heavy radial loads transmitted to the slewing gear is the challenge.
Advanced bearing arrangements from Ever-Power can handle these conditions and more. Solutions include:
Wheel drives – Ever-Power offers thin-section tapered roller bearings, thin section angular get in touch with ball bearings, CARB toroidal roller bearings and off-highway hub units (flanged and geared).
Slewing drives – Meant 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 operating challenges, Ever-Power can help you meet them. Working together with Ever-Power, you can accommodate increased external load, improved torque and more compact and lighter arrangements.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 level of worm gear couple and 2 nd, 3 rd stage was created with planetary
Ever-Vitality industrial, yaw and pitch and mobile phone slew drives are created to job 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 excess weight and size to a minimum on equipment such as tower cranes, aerial platforms, discharge booms, excavation and engineering equipment.
Their planetary structure allows them to withstand high torque values while maintaining lowered 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 products optimises torque effectiveness and radial load capability, in order to give best meshing between pinion and band gear.
For accurate adjustment, several versions have eccentric installation between the pinion axis and the casing axis. Their wide range of ratios enables selecting engine size and type which finest suits the customer’s.
This wide variety 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 correct positioning is necesary. These Ever-Electric power slewing drives are well suited for the most serious duties in every environment. The look of the planetary products optimizes torque overall performance and radial load potential, as a way to give ideal meshing between pinion and band gear. For appropriate adjustment, some types have eccentric installation between the pinion axis and the casing axis. Their wide range of ratios enables selecting electric motor size and type which greatest meets the customer’s requirements and application.

Description
Slewing equipment drives are used to put driven devices. They have already been tried and analyzed in many different applications, such as for example cranes, excavators, and drilling platforms. Ever-Power gear units for slewing gear drives have a modular design. They could be combined with an extended or short lantern gear drive on the output side. The mounted result pinions are manufactured based on the customer’s specs. On the input area, we offer solutions for both electrical motors and high-quickness or low-rate hydraulic motors, some of which are already standardized.
One frequently requested substitute, particularly as a equipment unit for slewing equipment drives in bucket wheel excavators, involves a Ever-Power planetary equipment device with a bevel or bevel helical gear device on the input side. The drive engine and a brake will be organized on a bracket on the apparatus product, so that the machine no longer needs to be aligned on internet site. A brake is usually always mounted between the motor and the apparatus unit as a way to fix the boom in a precise position. An overload safe practices mechanism can additionally be provided to protect the boom and the travel against inadmissibly huge loads.

Slew Drives, commonly referred to as a Slewing Gear or Slew Bearings, is a complete, ready to install system that contains a ball or roller slewing band bearing, drive teach, and completely enclosed housing. It can be customized with hydraulic or electrical motors, brakes, planetary gearboxes, corrosion protection, in addition to many other options.
Ever-Power decrease costs by replacing complicated in-house systems in equipment that rotate weighty loads and require features and innovation. Each comes with an unlimited slewing angle and range, move effortlessly and jolt-free, no slip-stick effect, and provide the most efficient transmission of high electrical power and torque conceivable. Our Slew Drives happen to be totally enclosed and sealed housing withstands harsh conditions and increases safety.
As a ready-for-installation program module, they replace countless individual parts. Slew drives are utilized for aerial platforms, defense technology, public transportation, forestry machine sectors, solar trackers, and more.

Planetary gear product with pinion shaft and prolonged housing at the output
Output pinion
Slewing gear drives for any power ranking and mounting position
For larger machines, the slewing gear drive can be comprised of various equipment units that impact on the same girth gear with external or internal teeth. We present the right blend of gear products for every requirement:
Our P series professional planetary gear devices and the X series professional bevel gear and bevel-helical gear systems are adequate for smaller torques of up to 500 kNm. A mixture of XP series industrial planetary gear units and X series commercial bevel-helical gear models provide larger torques as high as 4,000 kNm.
Slewing equipment drives are usually shaft-mounted designs. This signifies that the apparatus unit is mounted at the top and the pinion on the bottom. However, our drive answer is also offered as a bottom-mounting variant or “bottom-up” version – in cases like this the pinion is positioned on top. The lubrication, oil growth container and the seals will be adapted to the installation position.
