slew drive bearing for heavy pallet transporter,container carrier,crane,solar tracker and new energy field

slew drive is a new kind of slew products.it consists of worm,sleing ting,housing,motor and so on.Because the core part is slewing ring,so slew drive can bearing axial,radial loading and titling moment at the same time.Compare with the traditional slew products,NFB slew drive is easy to mount and maintain,and saves more space. Products can be widely used in heavy pallet transporter,container carrier,crane,solar trcker and new energy field.

Characteristics of the core componects:

1. slewing ring

    slewing ring can bear the axial load,radial load and tilting moment together.

It consists of mounting holes,external gear or internal gear,grease and seal,with this compact structure,it is easy to start and maintain.

2.Worm adn wheel transmission

    It gets larger transmission and more compact structure than helical gear

    It is line contact between the surface of action,and the bearing capacity is much higher than heli-cal gear

    Worm transmission is equivalent to screw drive.multi-teeth meshing transmission is stable and low noisy.

    Self-locking.When the lead angle of worm is less than equivalent friction angle between meshing teeth,the mechanism has self-locking and achieve backward self-locking.It means only the wormdrives worm wheel,adn the worm wheel cannot drive worm.For example:self-locking worm mechanism is used for security protection in heavy machinery. 

You can both buy by yourself and buy from us.It depends on the : voltage,power and speed.
