Slew Drive is a new type of slewing product, usually called slewing ring, which is usually composed of worm, slewing ring, housing, motor and other components. Since the core components are slewing bearings, they can simultaneously withstand axial forces, radial forces, and overturning moments. Compared with traditional rotary products, the new slewing drive features easy installation, easy maintenance and a greater degree of installation space.
Spherical worm gear reducer rotary drive device is a new type of rotary products, usually by worm, rotary support, shell, motor and other components.As the core part adopts rotary support and enveloping worm structure, it can reach multi-tooth contact, has the characteristics of large transmission torque and smooth operation, so it can bear large axial load, longitudinal load and strong overturning moment at the same time.
Compared with traditional rotating products, the spherical worm wheel rotary drive has the advantages of simple installation, easy maintenance and more space saving.The product can be widely used in the field of construction machinery and new energy, such as heavy plate transporter, container crane, truck crane, aerial working vehicle, solar power generation system and so on.
According to row of rolling elements,slewing bearings can be divided into single-row slewing bearings, double -row slewing bearings and multi-row slewing bearings. Slewing bearings also can be divided into roller slewing bearings and ball slewings depending on rolling element type.
Slewing bearings are also called rotary ring bearings,slewing rings or turntable rings which are usually used in these indusitries,such as port machine, metallurgical industry ,hoist and engineering machine, and so on. Luoyang Jiayu not only provide not only solutions for those applications,but also high-level slewing bearings research and development so that we can offer high precision slewing bearings.
Type of slewing rings
Four point contact ball precision slewing bearing(with inner ring gear,outer ring gear or without gear)
Double row different diameter ball slewing bearing(with inner ring gear,outer ring gear or without gear)
Tri-row cylindrical roller slewing bearing(with inner ring gear,outer ring gear or without gear)
Crossed roller slewing bearing(with inner ring gear,outer ring gear or without gear)
Four point ball slewing bearing with
We can produce whole slewing bearings with a diameter from 120mm up to 13000mm. In terms of segmented bearings, these are manufactured with a diameter of up to 17 metres.
When manufacturing slewing bearings. The material we choose mostly is 42CrMo,but sometimes structural hardening steels or alloys, special steels for hardening under controlled atmosphere.
These materials are manufactured by approved steel works.
Inspections are carried out at each significant step of manufacturing what makes it possible to achieve the specified quality.
Core hardening and tempering are carried out to reach required hardness.
