The slewing bearings used in bridge inspection vehicles are mainly single-row ball slewing bearings . The main function is to fix the boom, beam and other mechanisms and control the rotation of the control mechanism to carry a certain axial force and overturning moment.
The motor or reducer drives the gear to rotate, or the motor or hydraulic motor drives the worm to rotate, and the pinion or worm drives the slewing bearing to rotate, thereby driving the beams, arms and other mechanisms installed or connected to its base to rotate.
Selecting the appropriate slewing bearing can effectively increase the load, improve the safety performance and stability of the equipment, and increase the service life.
Slewing Bearing With External Gear
A Sslewing bearing or slewing ring is a rotational rolling-element bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill. Slewing bearing with External gear are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base. We produce different slewing bearing with external gear.
1.What’s kinds of teeth type for slewing bearing rings with external gear we often make?
Our company provided you with standard teeth, British standard teeth, stub teeth, helical teeth, worm gear, synchronous pulley and sprocket.
2.What’s the module of tooth for slewing bearing with external gear we often make?
For common standard metric model tooth and British standard DP1.75、DP2、DP2.5、DP3、DP3.5、DP4、DP5、DP6、DP8、DP16、DP5/7、DP3/4、DP4/5, we all can make.
The precision of tooth machining is 8 grade,9 grade,10 grade.
3.Tooth heat treatment of slewing bearing with external gears
Tooth heat treatment of slewing bearing with external gear includes tooth surface quenching, tooth surface &tooth root quenching and full tooth quenching.
Technical parameters required for slewing bearing selection as below:
1).Slewing bearing load (Includes axial load, radial load and tilting moment)
2). Percentage of each load and its occupation time
3). Speed or number of revolutions of the slewing bearing under each load
4).Circumferential force acting on the gear
5).Dimensions of the slewing bearing
6). Other operating conditions
The material, compressive property, abrasive resistance and hardness of balls will affect the load condition and service life of slewing bearing. Longwei slewing bearing Co., Ltd purchase balls from suppliers with high quality, and we will conduct test for the compressive property, abrasive resistance and hardness to eurens the quality of balls will meet the requirement.
