Description

Self - Locking Slewing Drives For Digger Derricks / Automotive Lifts

?

??? slewing drives is a new kind of slew products.it consists of worm,slewing 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, 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 tracker and new energy field.

Characteristics of the core components:

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 and 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 worm drives worm wheel,and 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.
Reliability
slewing drives are designed and tested to guarantee a 30-year field life. All aspects of engineering control are based on creating a low-cost, reliable solution. Using the same methods and procedures that earned us our ISO 9001 certifications, we qualify all the raw materials, components and final assemblies to meet these standards.

Performance

slew drives are powered with patented hourglass worm technology to give maximum survivability load-holding as well as increased efficiency and accuracy. Unlike standard worms which touch only one tooth, our hourglass worm engages 5-11 teeth on the pitch line of the ring gear from the hourglass thread. This increased tooth engagement gives the gearbox enormous strength and power.

?
Applications
Typical slewing drive applications include :

?

> solar trackers,

> wind turbines,

> truck cranes,

> man lifts,

> utility equipment,

> hydraulic equipment attachments,

> oil tool equipment,

>? tire handlers,

> digger derricks and automotive lifts.

?

There are many other applications as the slewing drive is perfect for applications requiring both load-holding and rotational torque from the same gearbox.

?
Specifications
Our base model sizes deliver performance ranges from 6kNm to 220kNm of holding torque, 200Nm to 63kNm of output torque, 500Nm to 271kNm of overturning moment load capacity, and gearbox reduction ratios of 30:1 up to 156,600:1. The mounting can be done horizontally, vertically or a combination of multiple axes.
