More Information
Summary:PURPOSE:To make manufacturing and assembly easy and to provide an effective sealing mechanism in a motor by installing a first ring member on either inner ring or outer ring of a bearing member and installing a second ring member on the other ring and by forming the first and the second ring member by press-working. CONSTITUTION:This motor is provided with a fixed member 2 and a rotary member 1 which is so supported as to rotate relatively to the fixed member 2. Between the fixed member 2 and the rotary member 1, bearing members 100, 200 are provided. Each of the bearing members 100, 200 has an inner ring 101, an outer ring 102 and a ball-like member 103 located between the inner ring 101 and the outer ring 102. A first ring member 211 is installed on either the inner ring 101 or the outer ring 102 through a washer 210 and a second ring member 212 is installed on the other. These ring members 211, 212 are formed by press-working. In such a structure, a desired labyrinth space can be formed by adjusting the thickness of the washer 210.
