Wheel drive and slewing drive solutions
Boosting mobile planetary gear unit performance
Mobile planetary gear units must provide reliable efficiency under extremely harsh conditions. In steering wheel drives, this means hefty radial loads, shock loads and tilting moves – all in a restricted readily available space. In slewing machines, coping with the large radial loads transmitted to the slewing gear is the challenge.
Advanced bearing plans 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 products (flanged and geared).
Slewing drives – Designed for the outcome pinion in slewing drives, Ever-Power gives 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-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-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-Electric power industrial, yaw and pitch and mobile slew drives are made to job seamlessly in applications requiring slew bearings or perhaps racks, perhaps in a large-capacity winch.
Ever-Electric power slewing drives are an important component in keeping excess weight and size to a minimum on devices such as for example tower cranes, aerial platforms, discharge booms, excavation and engineering equipment.
Their planetary structure allows them to withstand high torque values while maintaining decreased dimensions, lowered weight and high efficiency. The Dana Ever-Vitality slewing drives are suited to the most serious duties in every environment. The design of the planetary products optimises torque performance and radial load capability, so as to give perfect meshing between pinion and band gear.
For accurate adjustment, a few versions have eccentric mounting between your pinion axis and the casing axis. Their wide selection of ratios enables selecting engine size and type which very best suits the customer’s.
This broad range of Ever-Power planetary gear units is specifically made 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 works extremely well in all applications where accurate positioning is called for. These Ever-Electricity slewing drives are ideal for the most severe duties in every environment. The look of the planetary units optimizes torque efficiency and radial load capability, in order to give best meshing between pinion and band gear. For appropriate adjustment, some variants have eccentric installation between your pinion axis and the casing axis. Their wide selection of ratios enables selecting motor size and type which finest matches the customer’s requirements and request.

Ever-Power Gear Models for Slewing Gears
Slewing equipment drives are used to position driven machines. They have already been tried and analyzed in many diverse applications, such as for example cranes, excavators, and drilling systems. Ever-Power gear units for slewing gear drives possess a modular design. They are often combined with an extended or short lantern gear drive on the productivity side. The mounted result pinions are manufactured based on the customer’s features. On the input aspect, you can expect solutions for both electrical motors and high-swiftness or low-velocity hydraulic motors, a few of which already are standardized.
One frequently requested choice, particularly as a gear unit for slewing gear drives in bucket wheel excavators, contains a Ever-Power planetary equipment device with a bevel or bevel helical gear unit on the input part. The drive electric motor and a brake are arranged on a bracket on the gear device, so that the machine no longer should be aligned on site. A brake is definitely always mounted between your motor and the gear unit so as to resolve the boom in a defined position. An overload safety mechanism can additionally be provided to protect the boom and the drive against inadmissibly large loads.

Slew Drives, commonly referred to as a Slewing Gear or Slew Bearings, is definitely 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 electrical motors, brakes, planetary gearboxes, corrosion protection, and also many other options.
Ever-Power reduce costs by replacing complex in-house systems in equipment that rotate heavy loads and require efficiency and innovation. Each has an unlimited slewing angle and range, move smoothly and jolt-free, no slip-stick effect, and provide the most effective transmission of high electrical power and torque likely. Our Slew Drives will be completely enclosed and sealed casing withstands harsh environments and increases safety.
As a ready-for-installation system module, they Planetary Slew Drives replace many individual parts. Slew drives are used for aerial platforms, security technology, public transportation, forestry machine sectors, solar trackers, and much more.

Slewing equipment drives are usually shaft-mounted designs. This signifies that the apparatus unit is mounted at the top and the pinion on underneath. However, our drive remedy is also available as a bottom-mounting type or “bottom-up” version – in this case the pinion is positioned at the top. The lubrication, oil expansion container and the seals are adapted to the mounting position.
