In order to solve the problems of the technologies described above, the technological scheme that the utility model is taked is: a kind of electromagnetic fan clutch magnet fixed disc spring bearing, comprise outer ring and inner ring, outer fissure on the internal diameter of outer ring, septal fossula on the inner ring external diameter, single-row steel ball and retainer, the seal ring at bearing two ends, on the cross section of crossing bearing axis, outer fissure and septal fossula are connected to form by two circular arcs respectively, article two, an end of circular arc intersects, and the other end of two circular arcs of outer fissure and outer ring internal diameter intersect, and the other end of two circular arcs of septal fossula and inner ring external diameter intersect; Form two radius of arc of outer fissure and septal fossula greater than the radius of steel ball; Steel ball and outer fissure and septal fossula respectively have two point of contact.
On the cross section of crossing bearing axis, single-row steel ball contacts with 4 of outer fissure and septal fossulas, and is identical with the single-groove grooved ball bearing of sealing on axial dimension, and identical with double-row angular contact bal bearing on effect.In Design of The Electromagnetic Fan-clutch, the utility model has kept the advantage that seals single-groove grooved ball bearing and double-row angular contact bal bearing, overcome the shortcoming that seals single-groove grooved ball bearing and double-row angular contact bal bearing, axial dimension is little, simple in structure, cost is low, and it is less that the outer ring is subjected to external force to affect the generation swing in rotation.Crossing on the cross section of bearing axis, outer fissure and septal fossula are Gothic arch, i.e. peach-shaped, and the intersection point of two circular arcs is the summit of cusped arch.
Outer fissure and septal fossula are connected to form by two radiuses, circular arc that length is identical respectively.On the cross section of crossing bearing axis, two circular arcs that form outer fissure and septal fossula are symmetric in the steel ball both sides; Two point of contact of two point of contact, steel ball and septal fossulas of steel ball and outer fissure are symmetric in the steel ball both sides respectively.
The radius of arc of composition outer fissure and septal fossula is 1.02～1.18 with the ratio of the radius of steel ball.The radius of arc that forms outer fissure and septal fossula and the ratio of the radius of steel ball are greater than 1.18, and the bearing capacity of bearing sharply descends, and bearing life obviously reduces, and the outer ring will produce larger swing when load produces deflecting torque, affect the normal operation of magnet fixed disc; Ratio less than 1.02 o'clock, the lubrication effect of steel ball sharply descends in the motion, bearing temperature rise obviously raises, apparent friction increases and energy consumption obviously increases, and causes bearing life obviously to reduce.
The radius of arc of composition outer fissure and septal fossula is 1.04～1.14 with the ratio of the radius of steel ball.Preferred ratio.
Form the radius of arc of outer fissure more than or equal to the radius of arc that forms septal fossula.
The angle that the angle at the center of two point of contact connection steel balls of outer fissure, two point of contact of septal fossula connect the center of steel balls is 30～80
oThe size of angle affects the radial and axial carrying of electromagnetic fan clutch magnet fixed disc spring bearing and the ability of high-speed motion.
The angle that two point of contact of outer fissure connect the center of steel balls is connected the angle that two point of contact connect the center of steel balls with septal fossula be 40～70
oIt is preferred angle.
The utility model has the advantages that: single-row steel ball contacts with 4 of outer fissure and septal fossulas, in Design of The Electromagnetic Fan-clutch, the utility model has kept the advantage that seals single-groove grooved ball bearing and double-row angular contact bal bearing, has overcome the shortcoming that seals single-groove grooved ball bearing and double-row angular contact bal bearing.The utility model axial dimension is little, and is simple in structure, and cost is low, and it is less that the outer ring is subjected to external force to affect the generation swing in rotation.
