The slewing 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.
Single Row Four Point Contact Ball Slewing Bearingis composed of 2 seat rings.It features compact in design,and light in weight.The balls contact with the circular race at four points,via which the axial force,radial force and resultant moment may be born simultaneously.
It can be used for slewing conveyer, welding manipulator, light & medium duty crane, excavator, and other construction machinery, welding arms and positioners, light,medium duty cranes,excavators and other engineering machines.
The Single Row Crossed Roller Slewing Bearing is composed of two searings. It features compact in design, light in weight,high precision and small fitting clearance.
As the rollers are 1:1cross arranged,it is suitable for high precision mounting and capable to bear axial force,resultant moment and considerable large radial force.
The single-row crossed roller Slewing Bearings are widely used for hoisting,transporting,engineering machines as well as for marine crane products.
The Double Row Ball Slewing Bearing has three seat rings.The steel balls and the spacers may be directly arranged into the upper and lower races.Two rows of steel balls with different diameters are fitted according to the force bom.Such open mode fitting features extraordinary convenience.The load angles of both upper and lower races are 90°,which enable the bearing to bear large axial force and the tipping moment. When the radial force is larger than 1/10 of the axial force the races should be newly designed.
As the axle and the dimension of the double row ball slewing bearing are rather large,the bearing construction is sturdy ,hence it is especially suitable for tower cranes which require working radius over medium range,mobile cranes and loading and unloading machines
The Three Row Roller Slewing Bearing has three seatrings,which separate the upper,lower and radial races,via which the load of each row of the rollers may be specified.It may bear different loads simultaneously and its load capacity is the largest one among the four models.
Thanks to the large size of its axle and radius,it is sturdy and especially suitable for heavymachines which require large working radius.such as bucketwheel excavators,wheeled cranes,ship cranes,ladle turrets,heavy duty mobile cranes etc.
Mining machine, construction equipment, port hoisting machine, port oil transfer equipment, onshore and offshore crane, excavator,concrete machine, revolving grabbers and winches,plastic and rubber machine, weave machine, logging industry machines, wind-power generation,electronic power plant, water treatment machinery, drilling equipment and steering applications.
Coresun Drive Slewing Drive, Slewing Ring Advantage
1. Coresun Drive Slewing drive designed with hourglass worm shaft which provides more tooth contact and higher torque.
2. High transmission efficiency and accurate tracking
3. Easy installation and maintenance
4.Special heat treatment,corrosion resistance
5.We use framework oil sealing, so our slewing drive has higher dustproof and waterproof
6.Coresun Drive use 8 bolts on worm shaft, so it is much stronger
