110.32.1250 single cross row slewing-bearing without gear -for-long-screw-engineering drill Rig

With the rapid development of hydraulic transmission technology and the wide use of low speed and high torque motor in recent years, it is possible to use slewing bearing on the power turntable of large diameter drilling machine.

Slewing bearing is a kind of device used to support the platform of main engine slewing and to complete the space slewing operation. According to its structural, it can be divided into column type and rotary plate type. The rotary type also can be divided into supporting roller and rolling bearing type.

As a device for transferring power and driving drill pipe, the rotary table mainly adopts bevel gear transmission, which has complex structure and high manufacturing cost. In order to meet the construction needs of low speed, human torque and large diameter, as well as the design requirements of bearing alternating loads under various complex conditions, large special rotary bearing with large diameter should be selected to increase the reduction ratio of rotary transmission device. If according to the conventional mode design, is bound to cause the turntable structure more complex, huge volume, weight increase, cost is expensive, increase the gear, box processing, and bearing manufacturing workload, but also make the turntable installation and demolition difficulty, is not conducive to the development of the series of turntable. Large caliber drill as a large machinery, there are also many risks in operation, such as the new drill or stop drilling for a long time,drilling rig should open 2 speed operation at least 20 min, When the drill is not used for a long time, each exposed part should be coated with lubricating grease to prevent rust and so on.
