Single row cross roller Slewing Bearing with Internal gear 113 series for Conveyor Type Charging Machine

The slewing bearing is a special component that integrates rotation and transmission, reduces structural space and reduces equipment weight. In particular, radar turntables and armored rescue vehicle turntables require high-precision, low-noise, high-impact load, and stable rotation turntable equipment, all of which require dedicated rotation support.

Cross roller slewing bearing–inner teeth Bellless blast furnace top distributor is the key equipment on the top of blast furnace machine, its main function is to drive the rotation of chute and control the tilt of chute, so as to meet the requirements of different blast furnace operations.

The single-row cross roller swivel ring also consists of two inner and outer rings with a compact structure, high manufacturing precision, low weight and little assembly clearance. The inner ring and the outer ring are connected by rollers, the rollers are arranged in a 1: 1 cross, which can simultaneously absorb axial force, tilting moment and larger radial force.

Also it is widely used in lifting and transportation, military products, medical equipment, bucket wheel machines, park amusement machines, filling machines etc, which play a very important role in construction machinery products.

Our slew bearing 113 series are single-row cross roller slewing bearings with teeth on the inner ring, you can use a pinion with it to bring the slewing ring rotary.


Assembly three row roller Slewing bearing

Bellless blast furnace top distributor is the key equipment on the top of blast furnace machine, its main function is to drive the rotation of chute and control the tilt of chute, so as to meet the requirements of different blast furnace operations. The cross roller slewing bearing is an important component of bell-less blast furnace machine, and it is easy to fail in the harsh environment of heavy load, high temperature and high pressure for a long time, which will affect the operation of the whole blast furnace.

Because the lower slewing bearing is in the important position to connecting the preceding and following in the blast furnace machine, it is very difficult to disassemble and assemble, and the structure is close.

Even if the slewing bearing is removed from the machine, it is difficult to know its internal force and wear, which will also affect the subsequent work. Therefore, in order to get the force of the roller and raceway and the motion track of the roller in the slewing support, the simulation method is selected to observe.

The center axis of distributor often deviates from its geometric center due to the impact of charge, installation error, operating environment and the structural characteristics of distributor itself.

Be sure to regularly check the phenomenon of abnormal slewing support, blockage, etc., and regularly inject grease to ensure the smooth operation of the machine.
