Slew Drive with Worm Gear

Slew Drive with Worm Gear

Depending on featureSlew Drive with Worm Gear are divided into five types:

1.WE Series
The WE series is a good choice when you are in the Wild harsh working conditions and need anti-glued more stronger. WE series slewing drive is similar to the SE,but the difference is designed with curved tooth slewing ring, the output torque is increased, with the smooth running of a superior anti-sandstorm, field use, etc.

Advantage
I)   This is caused by FRB BEARINGS independent research and development, designing with the enclosed housing and curved tooth slewing ring. Better rigidity and stronger impact resistance
II)  FRB BEARINGS designing the WE Series use curved tooth slewing ring and Straight Worm; it is more touch and stronger anti-sandstorm
III) In Europe and America Mature markets, has been recognized by customers

Application
WE series slewing drive widely used for relative rotation parts of the construction machines.
I)   The Aerial platform Chassis rotation.
II)  The rotation of ship cranes.
III)  Drive the Grab machine gripper rotation

2.WVE Series
If you are looking for the perfect solution for the solar tracker, FRB BEARINGS advice you use WVE Series. The WVE series slewing drives are designing for big output torque, Used vertical housing base and original internal structure, large modulus worm designed with curved tooth surface, and its superior performance and vertical installation mode in the CSP or special industry has been applied.

Advantage
I)   FRB BEARINGS optimal design for the housing base, it is more thinner, higher strength, and vertical mounting structure, which greatly simplifies the user's structural design.
II)  With maturity of heat treatment process, FRB BEARINGS on tooth surfaces and raceways are heat-treated to make the product more durable.
III)  FRB BEARINGS rely on design and development team, can be customized solutions for professional users

Application
I)   WE series slewing drive widely used for relative rotation parts of the construction machines
II)  Solar power such as: CSP, CPV, Solar tower, Solar PV etc.

3.WDE Series
WDE series slewing drives inherits the advantages of the horizontal and the vertical, the horizontal and vertical slewing drive for modular designs while reducing design for customers connecting portion cumbersome structural design, structural design using the most simple to achieve 3D tracker.

Advantage
I)   This products are used unique modular design for the solar field; it is simultaneously rotate in azimuth & elevation.
II)  The products put into large-scale apply in dual axis CPV, Solar tower, PV etc. both at home and abroad.

Application
WDE series slewing drive widely used for relative rotation parts of the solar field.
CPV Dual axis tracker
I)   Solar tower dual axis tracker
II)  Solar PV dual axis tracker

4.WEA Series
For outdoor or indoor Humid environment such as the beach, desert etc., and WEA series slewing drive is the Optimization and upgrading of the WE. With a fully sealed design can meet your field use requirements.

Feature
I)   FRB BEARINGS optimal design for the housing base, it is thinner, higher strength, and full sealed design, which suitable for use in the wild
II)  FRB BEARINGS designed with full sealed which can effectively prevent corrosion of wind, sand, water on the device.

Application
WDE series slewing drive widely used for relative rotation parts of the construction machines and solar field.
I)   Solar heat, solar PV tracking power station
II)  Aerial platform Chassis rotation
III)  Drive the arm rotation of the crane truck

5.W Series
W series slewing drive is similar to the WE, but the difference is use open housing base with lower costs, you can always monitor the using of equipment, easy maintenance.

Advantage
I)   W Series slewing drive is use in the indoor or outdoor under the buildings, it can reduce the costs compare with the enclosed.
II)  W series slewing drive is easy for maintenance and monitor in any time.
III)  FRB BEARINGS are heat-treated the products tooth surface and raceways, greatly enhancing service life

Application
W series slewing drive widely used for relative rotation parts of the construction machines
I)   Aerial platform Chassis rotation
II)  Drive the arm rotation of the crane truck
