    Abstract: A motor includes a bearing housing and a stator. The stator includes a stator core, an insulator, and a conductor. The insulator is an insulating body covering at least a part of the stator core. The conductor is wound around the stator core via the insulator. The bearing housing and the stator are connected to each other by a main adhesive and an auxiliary adhesive. A curing time of the auxiliary adhesive is shorter than that of the main adhesive. Therefore, the bearing housing and the stator can be temporarily fixed by the auxiliary adhesive of which the curing time is short until the main adhesive is cured. Therefore, it is possible to suppress that the position of the stator is deviated with respect to the bearing housing until the main adhesive is cured.

  • Patent number: 9127712
    Abstract: The invention provides a rolling bearing assembly device having an inner race, an outer race, at least one row of rolling elements between the inner race and the outer race, and a sleeve mounted in the bore of the inner race. An annular elastic element is mounted axially between a radial bearing flange of the sleeve and the inner race, the elastic element having an inner bore that is able to bear against an outer surface of the sleeve so as to transmit a force having a radial component in the direction of the interior of the device.

  • Patent number: 8857061
    Abstract: A system and method for mounting a bearing assembly on a shaft includes an internal flange, external flange, and a sleeve. The internal flange is securable to the bearing assembly and has a displacement pin extending outward that defines an initial position of the bearing assembly relative to the shaft. The external flange is secured to the internal flange via fasteners passing through elongated holes. The external flange has an opening configured to receive the displacement pin. The external flange may be rotated when coupled to the internal flange with the fasteners between a first position where the external flange opening is not in register with the displacement pin and a second position where the external flange opening is in register with the displacement pin. A sleeve has a tapered outside diameter and is engageable with the external flange.

  • Patent number: 8851760
    Abstract: A bearing block can be secured to a fixture with quick release spring pins. The bearing block can also be secured to a shaft using a quick release spring pin. This facilitates the removal of the bearing block for repair or for cleaning whereby the bearing block can be removed without the necessity of tools or skilled labor. This thereby saves time in the removal, cleaning and reassembly or replacement of the bearing block and the device can be put back into service with significant time savings. This bearing block can be used in new designs or can be used to retrofit existing bearings and blocks.
