The Birth of New Model of Bearing to satify a Higher Requirements---SZ Bearing
Jiangsu Shuangzheng Machinery has been running consistently on the path of scientific research and innovation since the day of its constriction. Based on the increasing demands on working conditions from customers, our company has recently developed two new models of bearing, ball & roller combination slewing bearing and gear slewing drive.
The new slewing bearings are mainly composed of outer race, inner race, rollers and steel balls. Between each inner race and outer race, there is a horizontal linear raceway and a spherical raceway. The rollers are located in the horizontal linear raceway. The steel ball is located in the spherical raceway. The horizontally placed roller bears the axial force, the radial force is borne by the steel ball, and the tipping moment is borne by both. It can not only bear a large axial force, but also withstand a certain tilting moment and radial force, and the cross-sectional size is small, so the production cost is low. Compared with the three-row roller type slewing bearing, the ball & roller combination slewing bearing can bear the same axial force as the three-row roller type, but it is more suitable for the occasion where the axial force is large and there is basically no radial force and overturning moment.
Slewing drives, including the entire transmission system, are completely enclosed and lubricated, thereby reducing maintenance costs, so they require simple, fast installation, safe operation even in harsh environments, or have high load capacity and high torque Very popular in the application. Typical examples include manual lifts, drilling rigs, steering gears and gliding devices.
The new gear slewing drive is mainly composed of slewing bearing, pinion gear, housing, end cover and fast motor adjustment. Compared with the SE series and WEA series slewing drives, the speed of this structure is increased, and the speed can reach 20 rpm. Use our company's hydraulic motor, the speed does not exceed 15 rpm. The disadvantage is that there is no self-locking.
