CHARACTERISTIC OF STRUCTURE,PERFORMANCE AND APPLICATION
Three-row roller slewing ring has three seat-rings, which separating the upper, lower and radial raceways, via which the load of each row of the rollers maybe specified. it may bear different loads simultaneously and its load capacity is the largest one among the four models.
Owing to large size of its axle and radius, it is sturdy and especially suitable for heavy-duty machines which require large working diameter, such as buchetwheel excavators, wheeled cranes, deck cranes, port cranes, steel transporters, heavy -duty mobile cranes etc.
1. n1-number of lurbricating holes, evenly distributed, lubricating nipple M10??GB1152-1153-79.
2. Mounting hole may be replaced with screw hole, tooth width b may be taken as H-h.
3. Gear force of periphery given in the table is its maximum value, nominal force of periphery is taken 1/2 of the given value.
4. The trim top coefficient of outer and inner tooth is 0.1 and 0.2, respectively.
Gear heat treatment forms
Due to the need of transmission power or torque of slewing bearing, there are usually teeth in a ferrule. The general state of heat treatment of gear is normalizing or tempering. And the tooth surface and tooth root is IF Quenching
Slewing ring bearings can be widely used in lifting & transport machinery, mining machinery, construction machinery, port hoisting machinery, port oil transfer equipment, onshore and offshore crane, excavator, concrete machine, paper machine, plastic and rubber machine, weave machine, steel plant, electronic power plant, wind power generator, other construction and industry machines or equipments and other large rotary device.
