The difference between double and single direction thrust ball bearings

A seat ring that mates with the outer casing.

Type Receptive force is divided into single direction thrust ball bearings and two-way thrust ball bearings. One-way thrust ball bearings that accept one-way axial loads. Two-way thrust ball bearing, thrust ball bearing details: Composition Thrust ball bearing consists of three parts: seat ring, shaft ring and steel ball holder. A shaft ring that cooperates with the shaft. A two-way axial load is acceptable. Two-way thrust ball bearings in which the ring fits the shaft. The seat surface of the seat is spherical and has a self-aligning performance, which can reduce the influence of device errors. Thrust ball bearings cannot accept radial loads and have lower limit speeds.

Use It is only suitable for accepting parts with axial load and low speed. For example, when the crane hook is used and the normal state of the section is verified, the two raceways should be free from peeling damage and severe wear. The balls should be free of crushing and hemp. Point; the frame should be free of deformation, not touching the two raceway washers, and the balls are firmly gathered together. How to install the thrust bearing and the shaft is generally a transition fit. The fit between the race and the bearing bore is generally a clearance fit. The middle collar of the two-way thrust bearing should be fixed on the shaft to prevent rotation relative to the shaft. The device method of the thrust bearing is generally the case where the shaft rotates. Therefore, the cooperation between the inner ring and the shaft is a win-win cooperation, and the cooperation between the outer ring of the bearing and the bearing chamber is a clearance fit.

When installing a single direction thrust ball bearings, check the verticality of the shaft ring and the centerline of the shaft. The method is to fix the dial gauge to the end surface of the casing, so that the contact of the watch top rotates the bearing on the bearing shaft raceway, and observes the dial gauge pointer. In the future, if you want to do business on the earth, there is no Google optimization. survive. If the pointer is yawed, the centerline of the shaft and the axis are not perpendicular. When the case hole is deep, it can also be tested with an extended dial gauge.

There should be two aspects to the eco bag. On the one hand, it can be reused with natural materials. When the thrust bearing device is correct, the seat ring can automatically adapt to the rolling of the rolling elements, ensuring that the rolling elements are located in the upper and lower ring raceways. If the bearing is reversed, not only the bearing will not work properly, but the mating surfaces will be severely worn. Since the difference between the shaft ring and the seat ring is not obvious, the assembly should be extra careful and do not make mistakes. In addition, there should be a gap of 0.2-0.5mm between the seat ring of the thrust bearing and the bearing housing hole to compensate for the error caused by the inaccuracy of the parts processing and the device. When the center of the bearing ring is offset during operation, the gap can be Make sure it is automatically adjusted to prevent friction and normal operation. Otherwise, it will cause severe damage to the bearing.
