| titleOfInvention | Rolling bearing for electric tool motor |
| abstract | (57) [Problem] To provide a rolling bearing for an electric tool motor which achieves dustproofing of a bearing under low to high speed rotation, low torque, long life, and compatibility with resin. SOLUTION: A plurality of rolling elements disposed between raceway surfaces of an inner ring and an outer ring are rotatably held at substantially equal intervals by a retainer, and a plurality of rolling elements at a temperature of 40 ° C. are moved by a seal plate fitted in a seal groove of the outer ring. A rolling bearing in which a grease obtained by blending a urea compound with a synthetic hydrocarbon oil having a viscosity of 20 to 150 mm 2 / s is sealed, wherein the seal plate is made of an elastic body reinforced by a metal plate. A lip which is always in contact with the flat portion of the seal groove of the inner ring on the small diameter side, and a flange-shaped portion having a circular arc-shaped outer peripheral surface having a passage for discharging gas inside the bearing to the outside; The seal groove has an arc-shaped R surface portion in cross section corresponding to the flat portion and the flange portion that comes into contact with the lip, and always has a flange portion of the seal plate and an R surface portion of the seal groove of the inner ring. With a small gap between Rolling bearings for power tool motors. |
