The touch angle touch angle is a primary delineation parameter of the rolling bearing; when analyzing the bearing force, deformation, motion linkage and determining the bearing bearing capacity; it is necessary to determine the size of the touch angle.
The touch angle refers to the angle between the roll load vector at the midpoint of the roll body and the track touch area and the radial plane of the bearing. Usually the roll load acts in the middle of the touch area and the touch is straight; therefore, the touch angle refers to the touch. The angle between the line between the middle of the face and the roll and the radial plane of the bearing.
The contact angle of each type of bearing a = 0 degrees is called the radial bearing 0 degree < a <= 45 degrees; for the angular touch bearing or the radial thrust bearing 45 degrees < a < 90 degrees; called the thrust bearing to the tapered roller Sub-bearings and asymmetric spherical roller bearings; the touch angles of the rolling elements and the races of the races of the races are not the same. Usually; the touch angle of such bearings refers to the touch of the ferrules with and without ribs. Touch angle.
