上記軸受部は、各内輪が上記出力軸に圧入固定される第1,第2の2つのラジアルボールベアリングと、上記ステータの内径側に一体的に固定されるほぼ円筒状に形成された軸受ハウジングとを備え、
上記軸受ハウジングには、その一端側から上記第1ラジアルボールベアリングの外輪が収納される第1ベアリング収納部と、他端側から上記第2ラジアルボールベアリングの外輪が収納される第2ベアリング収納部とが設けられているとともに、上記第1,第2ベアリング収納部間には仕切壁が形成されており、
上記第1ベアリング収納部は、その内径がベアリング内のボール軌道に歪みを与えない程度に上記第1ラジアルボールベアリングの外輪を圧入し得る大きさに形成されており、
上記第2ベアリング収納部は、その内径が上記第2ラジアルボールベアリングの外輪を緩く嵌合し得る大きさに形成されているとともに、上記仕切壁と上記第2ラジアルボールベアリングの外輪との間には予圧バネが介装されていることを特徴とするアキシャルギャップ型電動機。A rotor having an output shaft and a stator having a bearing portion for the output shaft on the inner diameter side, and the rotor and the stator are opposed to each other with a predetermined gap along the axial direction on the output shaft In the axial gap type motor that has been
The bearing portion includes first and second radial ball bearings in which each inner ring is press-fitted and fixed to the output shaft, and a substantially cylindrical bearing housing that is integrally fixed to the inner diameter side of the stator. And
The bearing housing has a first bearing housing portion in which the outer ring of the first radial ball bearing is housed from one end side thereof, and a second bearing housing portion in which the outer ring of the second radial ball bearing is housed from the other end side. And a partition wall is formed between the first and second bearing storage parts,
The first bearing storage portion is formed in a size that allows the outer ring of the first radial ball bearing to be press-fitted to an extent that the inner diameter does not distort the ball raceway in the bearing.
The inner diameter of the second bearing storage portion is formed such that an inner diameter of the second radial ball bearing can be loosely fitted, and between the partition wall and the outer ring of the second radial ball bearing. Is an axial gap type motor characterized in that a preload spring is interposed.
