The secret of structure: Understanding the composition of thrust ball bearings

(I) Three core components

Thrust ball bearings are mainly composed of three core components: shaft ring, seat ring and steel ball cage assembly. They are like a small team that works together tacitly, each playing a unique role to jointly ensure the efficient operation of the bearing.

The shaft ring, as a component that closely cooperates with the shaft, is like a rider and a horse. The shaft ring closely follows the rotation of the shaft and accurately transmits the rotational motion of the shaft.

When the motor's rotor rotates at high speed, the shaft ring is firmly mounted on the shaft and dances synchronously with the shaft to ensure the stability of power transmission. The seat ring cooperates with the housing, like a solid fortress, to provide reliable support for the entire bearing system. In the elevator's traction machine, the seat ring is firmly fixed on the machine base, bearing the huge axial pressure from the car and counterweight, so that the shaft ring and steel ball cage assembly can operate safely on it.

The ball cage assembly is a smart dancer in the bearing. The steel balls roll happily in the raceway grooves, taking on the important task of reducing friction and transmitting loads. The cage is like a responsible leader, cleverly separating the steel balls evenly to prevent them from colliding with each other, ensuring that the steel balls can maintain a stable formation even when rotating at high speeds, and transmitting axial forces in an orderly manner.
