摘要： PROBLEM TO BE SOLVED: To prevent generation of distortion in an outlet side surface of a bolt 15 in a flange 34 by inserting the bolt 15 into a through hole 35 in the flange 34 to be engaged in it.
SOLUTION: The serration of the bolt 15 is put to bite the through hole 35 only in a range close to a bolt inlet. A biting margin for the serration 15d in the bolt 15 to an inner circumferential surface of the through hole 35 can thus be minimized. Quantity of flowing in thickness parts due to biting of the serration 15d can be minimized.

摘要： PROBLEM TO BE SOLVED: To provide a structure which can be inexpensively manufactured, in a holder for a bearing. SOLUTION: For forming a shape in which a plurality of plate-shaped segments 10 constituting a holder 5 for a bearing are warped in arched shape, heat shrinkage after molding is utilized without transcription from a molding metal mold as in the past. In this way, necessity for using the molding metal mold of particular shape curved as in the past is eliminated, so that a molding metal mold of general flat shape can be utilized. Consequently, a molding cost can be markedly reduced.

摘要： PURPOSE:To reduce the cost of a bearing by preparing the titled retainer from a synthetic resin so as to enable the assembly of conical rollers easily and rapidly, and simplifying and facilitating the molding of the retainer. CONSTITUTION:When the interval between ridgelines 16 and 16 is assumed to be L1 and the interval between ridgelines 17 and 17 is assumed to be L2, the dimensions L1 and L2 are set to values slightly smaller than the diameter (d) at said positions of the conical roller 10, so that the conical roller 10 has such a dimension that the conical roller 10 can be forced into the pocket part 14 by utilizing the elastic deformation of the ridge part from any of the outer diameter and the inner diameter, and the conical roller 10 does not drop out of any of the inner and outer sides. By constructing the molding by assembling and fitting female and male molding metal dies in a manner operable and slidable in the axial direction on the border of the ridgeline, the injection molding of the retainer can be effected extremely easily.

摘要： PROBLEM TO BE SOLVED: To reduce roller inclination at the time of assembling into a bearing and reduce temperature rise at the time of operation by forming projections on an inner wall of a circular member in a pocket. SOLUTION: A projection 7 having specified thickness is formed on an inner wall 2a of a circular member 2 of a pocket 4 of a holder 1. The projection 7 may be preferably formed inside the pocket 4 by two across its center axis with equal spacings therefrom in view of stability of the cylindrical rollers. The projections 7 may be on both sides of the inner wall of the pocket 4. An end face of the cylindrical roller fitted into the pocket 4 is slightly inclined and abutted against the projections 7. The inclination of the roller itself is reduced. The roller is not in contact with the side surface of an inner ring, so that it is easily assembled. Lubricant is kept in a recession 6 between the projections 7, and a recession 8 around them. Lubrication shortage is not generated at the time of operation even when a gap between the projections 7 and the cylindrical roller end face is decreased. Temperature rise is suppressed at the time of operation, and performance is improved.

摘要： PROBLEM TO BE SOLVED: To prevent a sliding contact surface from being worn out or prevent an inner ring from being hardly inserted due to inclination of a roller by a method wherein a sliding contact surface of a roller stopper is formed into a diverged shape with its column facing part being widely spreaded and the maximum width of the sliding contact surface is made substantially equal to the maximum width of the roller stopper part. SOLUTION: A column part 2 of a pocket 1 is formed with a roller stopper 3 expanding at a side of the pocket 1, a roller stopper 3 is formed with a flat top end surface, 32 which is continuous with a slant sliding contact surface 31 slidingly contacted with the roller. The sliding contact surface 31 is formed into a diverging shape which is gradually widened from the top surface 32 toward a side of the base part 33, and a base part width having the maximum width of the sliding contact surface 31 is equal to the maximum width of the roller stopper 3. Accordingly, the synthetic resin cage A can expand a contact width with the roller along with a feature that a middle part of the sliding contact surface 31 is contacted with the roller and then a wear of the sliding contact surface 31 can be prevented. In addition, an inclination of the roller can be prevented and in the case that the cage A is applied in the roller bearing having an outer ring flange, the roller is held by the cage A and when the inner ring is inserted into an inner circumference of the roller row, it is possible to prevent disadvantage that it may be hardly inserted into it.

摘要： PURPOSE:To secure a bearing at the specified accuracy by means of injection molding alone, by opening a gate in a bridging part bridging two-strip paired rings, and molding these rings. CONSTITUTION:Two-strip rings 5 of plastics are molded on an outer circumferential (setting) surface 7 of the ball bearing constituted of an outer ring 1, an inner ring 2, a cage 3 and a ball 4, but these elements are embedded in an annular groove 6 at the base, and projected out of the outer circumferential surface 7. And, both these rings 5 are connected with each other by a bridging part 13 constituted of synthetic resin burying a depression part 11 in depth H installed on the outer circumferential surface 7. These rings 5 are molded by means of injection molding of synthetic resin, between a metal mold 10 and the outer circumferential surface 7 via a runner 8 and a gate 9, by this metal mold 10. And, the gate 9 is opened at the center of the bridging part 13. With this constitution like that, a bearing at the specified accuracy is securable by means of injection molding alone, without entailing any polishing work afterward.
