  • ANALYSIS OF SLEWING BEARING LOAD OF A ROTATING

    2.1 with a ring gear of a bearing 3.1. By rule, a slewing slewing bearing 3 (Fig. 1d) consists of an inner ring gear 3.1, which is bolted to the support and movement mechanism L 1, and a toothless outer ring 3.2, which is bolted to the rotating platform L 2. Rolling elements (balls, rollers) are positioned between the rings in one or more races.

  • Fatigue life analysis of slewing bearings in wind

    2018-6-1 · Slewing bearings are important components of wind turbines and composed of a yaw bearing and a pitch bearing. They have driving teeth in the inner or outer ring that drive the pinion gear and transmit torque to achieve the wind turbine yaw and pitch movement, as shown in Fig. 1.The common yaw bearing is a four-point contact ball slewing bearing with a zero cross-section gap or microsection …

  • Ball Bearing - 3D CAD Models & 2D Drawings

    A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least three races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is ...
