What is tapered roller bearing
The ability of a single row tapered roller bearing to bear axial load depends on the contact Angle, that is, the outer ring raceway Angle. The greater the Angle, the greater the axial load capacity. The largest amount of tapered roller bearings is single row tapered roller bearings. Double row tapered roller bearings of small size are used in the front wheel hub of the car. Four rows of tapered roller bearings are used in heavy machines such as large cold and hot rolling mills.
What is the raceway crown of tapered roller bearing inner ring
In order to obtain raceway surface with raceway crown, the surface of grinding wheel must be trimmed into concave working surface. The grinding wheel is formed by adjusting the Angle β between the movement track of the diamond pen on the grinding wheel dresser and the center line of the grinding wheel shaft. In other words, the diamond horizontal dressing wheel is changed into an inclined dressing wheel, and the cylindrical surface formed by the original straight plain line is trimmed into a hyperbid formed by the curved plain line.
Convex raceway machining adjustment method
1. Adjust the Angle between the workpiece shaft and the grinding wheel shaft to ensure that the ring axis is parallel to the axis of the grinding wheel.
2. Calculate the β value according to the workpiece size and technical conditions.
3. Align the center position of the grinding wheel width. Firstly, the position of the diamond nib is adjusted, and the track of the diamond nib is pre-adjusted to pass the intersection point of the center line of the width of the grinding wheel and its axis, so as to ensure the ideal symmetrical raceway crown shape (Figure 3). If the running track of the grinding wheel dresser does not pass the intersection point between the center of the grinding wheel width and the axis and is left or right, the highest point of the raceway crown formed will also be left or right. After grinding the product, measure the raceway crown Angle with the instrument. If the value increases or decreases, it means that the track of the diamond nib does not pass the intersection, and it needs to be trimmed. If the measurement raceway crown Angle increases, it is necessary to move the base seat of the grinding wheel dresser to the non-reference surface, and the correction Angle remains unchanged. Then the grinding wheel is dressed until the track of the diamond nib passes the intersection point.
4. Forming fine trimming of grinding wheel. After grinding the product, the convex measurement was compared with the profile meter, and then the grinding wheel was fine-tuned to obtain the relatively ideal symmetrical concave grinding wheel, and the proper convex and symmetrical raceway was grinded.
