Description

  The present invention relates to a bearing component lifting tool for lifting a bearing component of a large split roller bearing.

  Large-sized rolling bearings that support large-diameter shafts of construction machinery, steel production equipment, general industrial machinery, etc., and the bearings that are sandwiched between the protruding parts in the radial direction, such as the crank of the crankshaft, or members that are difficult to remove A split bearing in which an inner ring and an outer ring are divided into two parts is used for the one mounted on the inner ring. The assembly work of such a large split roller bearing needs to be performed in a limited space, and heavy bearing parts must be assembled in a state of being lifted by a crane or the like. Become.

  The bearing component of such a split large rolling bearing includes a rolling element that rotatably holds a plurality of hollow rollers as rolling elements on a shaft pin that is passed between a pair of side plates of a ring-shaped or semi-ring shaped cage. There is a cage integrated part. When lifting this rolling element / retainer-integrated bearing component, previously, screw holes were drilled in the outer peripheral surfaces of the pair of side plates of the cage, eyebolts were attached to these screw holes, and lifted with a wire rope, etc. It was. For this reason, it is necessary to increase the wall thickness in order to secure the strength of the side plate for forming the screw hole, and there is a problem that the roller load is shortened and the bearing load capacity is restricted.

  With respect to this problem, a pair of vertical suspension members provided with lifting projections inserted through the lifting holes inserted in the pair of side plates of the retainer, A lifting tool for bearing parts has been proposed in which a lifting protrusion provided on a pair of suspension members is inserted into a lifting hole of a pair of side plates from the axial direction. (For example, refer to Patent Document 1).

  The one described in Patent Document 1 is a fixed suspension member in which one of a pair of suspension members is fixed to one end of a rod, and the other is a movable suspension member that is slidably fitted to the other end of the rod together with a spacer. The lifting protrusions projecting outward from each other are provided at the lower ends of the pair of suspension members. The spacer has a substantially cylindrical shape having a slit penetrating in the axial direction. By loosening or tightening a fastening bolt perpendicular to the slit, the spacer is opened and closed to be attached and detached. The movable suspension member is fixed by a tightening nut that is screwed to the other end of the rod.

  Moreover, in the Example of patent document 1, the protrusion part for lifting of a fixed suspension member and a movable suspension member is provided in the upper and lower steps, and the tapered roller bearing which hold | maintained the tapered roller on the shaft pin diagonally passed between the side plates of a holder | retainer. The bearing parts are lifted. In addition, when lifting the bearing component of the cylindrical roller bearing holding the cylindrical roller on the shaft pin that passes between the side plates at a right angle, the lifting protrusions of the suspension members are provided at the same height position.

JP-A-11-101245

  The suspension tool for a bearing component described in Patent Document 1 does not need to increase the thickness of the side plate of the cage, and can increase the bearing load capacity. However, the outward lifting protrusions of the pair of suspension members When inserting the spacer into the lifting holes of the pair of side plates from the inside in the axial direction, the spacer is removed, the movable suspension member is moved inward once, and then the movable suspension member is moved outward to lift the projection for lifting. Has to be inserted into the lifting hole and a spacer needs to be attached, and therefore, there is a problem that it takes much time to attach the lifting tool to the bearing part.

  In addition, since the set interval between the pair of suspension members is constant, bearing parts with different spans between the side plates provided with the lifting holes cannot be lifted, and the height positions of the pair of suspension pins are also changed. Therefore, bearing parts of different types cannot be lifted, such as cylindrical roller bearings and tapered roller bearings having different inclination angles of the shaft pins holding the rollers. For this reason, there is also a problem that lacks versatility. Furthermore, since the spacer and its fastening bolt are required, the number of parts increases, and the spacer and the fastening bolt that are attached and removed in a work place that is narrow and has poor visibility may be lost.
