  • Patent number: 10816089
    Abstract: A gear unit for a motor vehicle including a rotatable worm gear shaft rotating about a rotation axis and cooperating with a worm gear wheel in an engagement region spaced from the rotation axis. A pivotable rotary bearing mounts the worm gear shaft on a housing on one side of the engagement region and a loose rotary bearing, pretensioned in the direction of the spacing axis, mounts the other side in the housing. A support device supports the pivotable rotary bearing on the housing in the direction of the rotation axis. To optimize engagement between a worm gear shaft and a worm gear wheel, the pivotable rotary bearing pivots relative to the housing about a pivot axis perpendicular to the rotation axis and to the spacing axis. A support point of the support device is offset relative to the rotation axis along the spacing axis towards the engagement region.

  • Patent number: 10523083
    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: 8888374
    Abstract: A bearing with antiskid design used in combination with a circular spline to form a harmonic drive, and the circular spline is provided with an inner toothed portion, the bearing includes: an elliptical gear plug, a flexible ball bearing, and a flexible spline. Between the flexible ball bearing and the flexible spline are disposed a first and second antiskid members, and the arrangement of the first and second antiskid members prevents the axial slippage between the flexible ball bearing and the flexible spline, thus improving stability and transmission accuracy of the harmonic drive.

  • 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.

  • Patent number: 8840312
    Abstract: A bearing assembly cooperates with a bearing seat formed in a bearing housing and includes a bearing having an inner ring, an outer ring and a rolling element in engagement with the rings and an anti-rotation device. The anti-rotation device engages the outer ring to the bearing housing limiting rotation of the outer ring within the bearing seat. The anti-rotation device includes a first feature engaging the outer ring and a second feature engaging the bearing housing. The features limit the rotation of the outer ring within the bearing seat. The first feature has an internal surface for engagement the outer ring and the second feature includes an engagement surface for engaging a protrusion extending from the bearing housing.

  • Patent number: 8826542
    Abstract: In summary, the invention relates to a method for forming an end-side toothing arrangement of a roiling bearing, in particular a wheel bearing. The aim is to improve the uniformity of the end-side toothing arrangement and to allow a greater tooth depth. This is achieved by two method steps in that, in a first step before the reshaping of an end piece of a hub, a die is axially arranged on the rolling bearing in a preassembled state and, in a second step during the reshaping of the end piece and the shaping of the end-side toothing arrangement, the die radially delimits a radial recess of the rolling rivet collar as it forms. In addition, the die reduces or prevents radial widening of the inner ring.

  • Patent number: 8786150
    Abstract: A rotor shaft is supported in a rotatable manner at both ends by bearings respectively disposed to a housing forming a part of a stator and provided with a positioning portion of the bearing in at least one shaft end. The positioning portion is formed of an annular step-like rise portion that abuts on a circular arc surface provided to an inner ring corner of the bearing. A rotor shaft capable of holding the bearing in a stable manner over a long period is thus obtained without increasing the number of components and the numbers of working processes and assembly man-hours for the shaft. It thus becomes possible to solve problems, such as an increase in cost due to a large amount of working margin and increases of the direct material cost and in weight due to a larger finishing diameter of the shaft.

  • Patent number: 8746986
    Abstract: A spline lubrication apparatus is disclosed for lubricating a spline of a pump drive. The apparatus includes a housing and a rotatable spline which is disposed within the housing. The spline includes a shaft having a plurality of longitudinally extending splines. A gear is rotatably supported within the housing and includes a splined bore for the rotatable reception therein of the rotatable spline. An adapter is secured to the housing and defines a cavity for the rotatable reception therein of the splines and splined bore. A plurality of pockets are in fluid communication with the cavity such that when the splines and splined bore are rotating within the cavity, the flow of the lubricant within the cavity around the splines and splined bore is interrupted by the pockets. The arrangement is such that the flow of lubricant collects within the pockets and cascades onto the splines and splined bore for enhancing the lubrication thereof.
