Selecting a suitable slewing bearing can effectively improve the safety and stability of the equipment, and tooth quenching can improve the wear resistance of the teeth, thereby increasing the service life of the slewing bearing.
Application principle of slewing bearing
The motor or reducer drives the pinion to rotate, and the pinion drives the slewing bearing to rotate, so that the upper mechanism connected to it rotates with it, so as to control the steering of the cab and the mechanical arm. The slewing bearing used in rock drilling machinery is required to carry large axial force, overturning moment, impact force and gear circumferential force, and has higher requirements on the clearance, installation size, gear wear resistance, heat treatment process and material of the slewing bearing.
