Description

  The present invention is, for example, incorporated in a drive system of an automobile and used for a constant velocity joint that transmits rotational force at a constant speed between rotating shafts that exist on a non-linear line. It is about.

For constant velocity joints incorporated in the drive system of automobiles, etc., a retaining structure has been used in the past in which joint internal parts and shafts are releasably fitted in order to simplify maintenance work such as boot replacement. . In the structure, a groove is formed at the end of the shaft, and a retaining ring is provided in the groove, and is engaged with a contact surface formed on the joint internal part by elastic expansion of the retaining ring. Then, an angle is provided to the contact surface that interferes with the retaining ring when the shaft is pulled out, and the retaining ring is reduced in diameter by the component force of the interference force with the retaining ring to remove the fitting (patent document) 1, Patent Document 2).
Japanese Patent Laid-Open No. 08-68426 Japanese Utility Model Publication No. 64-5124

  In Patent Document 1, the retaining ring mounting position is on the non-end face side of the shaft, and a tool engaging groove for reducing the diameter of the retaining ring is provided on the end face of the inner ring, so that assembly and disassembly are possible. In this case, time and cost have to be spent on machining the tool engagement groove of the inner ring.

  Further, in Patent Document 2, it is disclosed that the retaining ring is reduced in diameter so as to come out of the shaft. However, how to manage the angle of the abutting portion for establishing the specification that comes off and the specification that does not come off. Was not shown to do.

  In view of the above problems, the present invention provides a structure for preventing a shaft from coming out of a constant velocity joint without increasing the types of inner rings and easily avoiding mixing of parts.

According to the present invention, the constant velocity joint shaft slip prevention structure includes an inner ring of a constant velocity joint having a shaft insertion hole, a shaft having a ring-shaped retaining ring groove located in the insertion hole of the inner ring, and elastically and reduced in diameter and a retaining ring provided on the retaining ring groove, in order to impart shrink force to stopper plate wheels when applied the force pulling on the shaft, perpendicular to the drawing direction of the shaft the first contact portion so as to form the inner ring is inclined a surface at the reference angle β and the withdrawal direction of the shaft for imparting enlarged force to retaining ring when applied the force pulling the shaft A second abutting portion inclined at an angle α with respect to a plane perpendicular to the shaft is formed on the shaft, and the first abutting portion is a portion having a diameter larger than the insertion hole that abuts the outer peripheral surface of the retaining ring. The second contact part is the tip side of the retaining ring groove. Wall, is inclined from the middle of the open end side, both the angle alpha, the relationship between the beta is characterized in that it has a 0 ° <α ≦ β.

  When the inner ring abutment is fixed at an angle β and it is difficult to remove the shaft and the inner ring, the retaining ring and the abutment interfere with each other even if you try to pull out the shaft by bringing them closer to α = β. It will disappear.

  In particular, when the specification is such that the shaft and the inner ring are difficult to disassemble, by setting 0 ° ≦ (β−α) ≦ 19 °, it is difficult to disassemble the retaining ring without shearing.

  In addition, when it is desired that the shaft and the inner ring be easily disassembled, the relationship between the two angles is set to 19 ° <(β−α), so that when the shaft is pulled out, the component force is reduced in the direction of reducing the diameter of the retaining ring. It can be pulled out easily. That is, it is possible to obtain specifications that are difficult to disassemble and specifications that are easy to disassemble simply by changing the setting of the angle α of the contact portion of the shaft.

  The contact portion can be formed at the spline end portion of the inner ring, or can be formed in the spline.

The present invention includes a contact portion formed on a shaft that applies a force in the diameter-enlarging direction to the retaining ring, and a contact portion formed on an inner ring that applies a force in the diameter-reducing direction to the retaining ring. With the abutment portion as the wall of the retaining ring groove, the inclination angle of each abutment portion is based on a plane perpendicular to the shaft drawing direction, the angle of the retaining ring groove wall is α, and the abutment portion of the inner ring The angle of β is β, and the relationship between both angles α and β is
By setting 0 ° <α ≦ β, the shaft and the inner ring can be selected and assembled when the shaft and the inner ring can be attached and detached.

  That is, by approaching α = β, the retaining ring does not come off due to interference even if the shaft is pulled out. Further, by setting α <β and increasing the difference, when the shaft is pulled out, a component force acts in the direction of reducing the diameter of the retaining ring, and the retaining ring is reduced in diameter in the retaining ring groove so that it can be easily pulled out.

  Therefore, when manufacturing multiple constant velocity joints with specifications that allow the shaft to be removed from the inner ring and specifications that prevent the shaft from being removed, the angle on the shaft side that is easy to process while keeping the angle β on the inner ring side constant. By changing α, it is possible to cope with a plurality of combinations, and the inner ring can be shared, so that the unit cost of parts can be reduced. In addition, it is only necessary to manage multiple shafts for one inner ring. Compared to manufacturing parts with different angles for both the inner ring and shaft, the types of parts management are reduced, and the contact part is mistaken. It is possible to reduce the number of man-hours to manage so as not to mix things with different angles and to make the wrong combination of inner ring and shaft.

  Embodiment 1 of the present invention will be described below with reference to FIGS. 1 to 3 and FIG. 4. Embodiment 1 shows an example in which a contact portion with a retaining ring is provided at a spline end portion of an inner ring. For convenience of explanation, the description will be made assuming that the left side in the figure indicates the tip side, and the right side in the figure indicates the opposite side.

  In FIG. 1, the fixed constant velocity joint 1 includes an outer ring 2, an inner ring 3, a torque transmission ball 4, and a cage 5 for the torque transmission ball 4. A shaft 6 that transmits torque is fitted and attached to the inner ring 3. The constant velocity joint is not limited to the fixed type constant velocity joint 1 and may be a sliding type constant velocity joint.

  The outer ring 2 has a large number of curved guide grooves 7 in the axial direction on a spherical inner surface. The inner ring 3 is formed with a large number of curved guide grooves 8 in the axial direction on a spherical outer diameter surface, and an insertion hole 9 for fitting the shaft 6 is formed in the axial direction. A spline 10 is formed on the inner peripheral surface of the insertion hole 9 in the axial direction. An inner ring 3 is provided on the inner surface of the outer ring 2, and a torque transmission ball 4 is positioned via a cage 5 on a ball track formed in cooperation with both guide grooves 7, 8 to form a fixed constant velocity joint. is doing.

  2 and 3, an axially extending spline 11 that engages with the spline 10 formed in the insertion hole 9 of the inner ring 3 is formed and coupled to the outer periphery of the end portion of the shaft 6.

The outer diameter of the spline 11 located on the front end side of the shaft 6 is reduced in diameter so that the retaining ring can be reduced in diameter when passing through the smaller diameter of the inner ring spline 10 when fitted to the inner ring spline 10. A ring-shaped retaining ring groove 12 having a depth that does not interfere with the retaining ring is formed as shown in FIGS. The position of the retaining ring 13 may be within the range of the length of the insertion groove 9 and may be at a position where the spline 11 is terminated at the tip of the shaft 6.

  A ring-shaped retaining ring 13 having a circular cross section is provided in the retaining ring groove 12. The retaining ring 13 is ring-shaped but partially cut away, and enters the retaining ring groove 12 with a reduced diameter. A part of the retaining ring 13 protrudes outward from the outer diameter of the shaft 6 (the outer diameter including the spline 11) in a state where a force of reducing the diameter is not applied.

  The wall on the distal end side of the retaining ring groove 12 is an abutting portion 12a with which the retaining ring 13 abuts when a pulling direction force is applied to the shaft 6, and extends from the root of the groove to the opening end with respect to the pulling direction of the shaft 6. It is inclined at an angle α with respect to a right angle surface. The contact portion 12a may be inclined from the root of the groove and the middle of the open end.

  A diameter 14 larger than the insertion hole 9 and a taper 15 are formed on the distal end side of the shaft 6 of the insertion hole 9 by performing diameter expansion processing. The large diameter 14 is formed continuously with the end of the spline 10 provided in the insertion hole 9. The end of the spline 10 is formed to be inclined.

  The shaft 6 is attached to the inner ring 3 by placing the retaining ring 13 in the retaining ring groove 12 and reducing the diameter of the retaining ring 13 and then inserting the shaft 6 into the insertion hole 9. At this time, the shaft 6 is inserted into the insertion hole 9 while the end surface of the spline 10 of the insertion hole 9 is in contact with the retaining ring 13 (in the direction of arrow A in FIG. 3). When the tip of the shaft 6 comes out of the insertion hole 9 of the inner ring 3, the shaft 6 comes into contact with the end of the insertion hole 9 of the inner ring 3 on the opposite end side to prevent insertion.

  At the location where the insertion of the shaft 6 into the insertion hole 9 stops, the retaining ring 13 is positioned at the large diameter 14 and the contact with the spline 10 is eliminated. Expand the diameter. When the diameter of the retaining ring 13 is increased, the outer peripheral surface side of the retaining ring 13 is held in contact with the large diameter 14 by an elastic force. In this state, the retaining ring 13 is not completely expanded but abuts against the large diameter 14, and only a part of the retaining ring 13 protrudes from the outer diameter of the shaft 6. Therefore, when the shaft 6 is pulled out in the direction of arrow B in FIG. 2, the contact portion 16 with the retaining ring 13 is formed on the continuous surface of the spline 10 and the large diameter 14.

  The contact portion 16 is located on the tip side outside the axial range of the spline 10. When the shaft 6 is moved in the direction of arrow B in FIG. 2 and the shaft 6 is pulled out, the abutting portion 16 is inclined at an angle β with respect to a plane perpendicular to the pulling direction of the shaft 6. Yes. The contact portion 16 is inclined so as to contact the outer peripheral side of the ring-shaped retaining ring 13. The contact portion 16 is formed by an inclined surface at the end of the spline 10 and a large diameter 14.

  The angles α and β of the contact portions 12a and 16 have the following relationship.

        0 ° <α ≦ β

    The angle β is in contact with the outer peripheral surface of the retaining ring 13 and gives a component force for reducing the diameter of the retaining ring 13.

  In addition, the angle α gives a component force that abuts the inner peripheral surface of the retaining ring 13 and expands the diameter of the retaining ring 13.

  For example, in the case of α≈β, as shown in FIG. 4, when the shaft 6 is pulled out, the contact portions 12a and 16 with which the retaining ring 13 abuts are substantially parallel, and the forces F1 and F2 acting on the retaining ring 13 are Since the interference force causes a component force to reduce the diameter of the retaining ring 13, it is difficult to disassemble the shaft 6 and the inner ring 3 unless the retaining ring 13 is sheared.

  In particular, when the applicant experimented, it was difficult to disassemble the retaining ring 13 without shearing under the condition of 0 ° ≦ (β−α) ≦ 19 °. Therefore, when selecting a specification that makes it difficult to disassemble the shaft 6 and the inner ring 3, α and β in this range may be combined.

  According to the applicant's experiment, if the condition of 19 ° <(β−α) is satisfied, when the shaft 6 is pulled out in the direction of arrow B in FIG. , F4 are not parallel to each other, and a component force for reducing the diameter of the retaining ring 13 is generated as a force acting on the retaining ring 13, so that the shaft 6 and the inner ring 3 can be easily disassembled. Therefore, when selecting a specification for disassembling the shaft 6 and the inner ring 3, α and β in this range may be combined.

  That is, by preparing the inner ring 3 with the contact angle fixed at β and the plurality of shafts 6 with the contact angle formed with α, the inner ring 3 and the shaft 6 can be disassembled by combining the inner ring 3 and the shaft 6. You can choose between specifications that you can easily do and those that you can't. Of course, even when the specification is such that the inner ring 3 and the shaft 6 can be disassembled by selecting these angles, it is difficult to disassemble the inner ring and the shaft without using a tool.

  In particular, the number of man-hours for management can be reduced and the overall cost can be reduced compared to preparing and managing a large number of bearings having different contact angles on the inner ring 3 of the constant velocity joint.

  Next, the second embodiment will be described with reference to FIGS. 5 to 7. The same components as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. Embodiment 2 shows an example in which a contact portion with a retaining ring is provided on a spline of an inner ring. For convenience of explanation, the description will be made assuming that the left side in the figure indicates the tip side, and the right side in the figure indicates the opposite side.

  A ring-shaped groove 17 extending in a direction perpendicular to the shaft 6 is formed in the middle of the insertion hole 9 formed in the inner ring 3 on the tip end side of the spline 10. The depth of the groove 17 is slightly deeper than the height of the spline 10. The groove 17 is formed in a size that can receive the retaining ring 13, and the opening of the retaining ring groove 12 and the opening of the groove 17 described above with the shaft 6 fitted in the insertion hole 9 of the inner ring 3. Are facing each other.

  The wall on the opposite end side of the groove 17 is inclined so that the base side becomes the tip side. This inclined wall serves as a contact portion 18 with the retaining ring 13 when a force in the pulling direction of the shaft 6 is applied. The inclination angle of the contact portion 18 is defined as an angle β with reference to a plane perpendicular to the drawing direction of the shaft 6. The contact portion 18 is inclined so as to contact the outer peripheral side of the retaining ring 13.

  The shaft 6 is attached to the inner ring 3 by placing the retaining ring 13 in the retaining ring groove 12 and reducing the diameter of the retaining ring 13 and then inserting the shaft 6 into the insertion hole 9. At this time, the shaft 6 is inserted into the insertion hole 9 while the end face of the spline 10 of the insertion hole 9 and the retaining ring 13 are in contact (in the direction of arrow A in FIG. 6). When the tip end of the shaft 6 comes out of the insertion hole 9 of the inner ring 3, the end of the insertion hole 9 on the opposite end side contacts the shaft 6 and insertion is prevented.

  At the place where the insertion of the shaft 6 into the insertion hole 9 is stopped, the contact with the inner diameter of the spline 10 is eliminated, so that the reduced retaining ring 13 is expanded by elasticity. When the diameter of the retaining ring 13 is increased, a part of the outer peripheral surface side of the retaining ring 13 protrudes into the groove 17, so that when the shaft 6 is pulled out in the direction of arrow B in FIG.

  The angles α and β of the contact portions 12a and 18 are shown in FIG. 7 under the condition of α≈β or 0 ° ≦ (β−α) ≦ 19 ° under the same conditions as in the first embodiment. Thus, the forces F5 and F6 (see FIG. 7) acting on the retaining ring 13 interfere with each other, and the shaft 6 and the inner ring 3 cannot be disassembled unless the retaining ring 13 is sheared.

  Further, under the condition of 19 ° <(β−α), as the forces F7 and F8 (see FIG. 5) acting on the retaining ring 13, the retaining ring 13 is moved in the direction of reducing the diameter (in the direction of the central axis of the shaft). Since a force is generated, the shaft 6 and the inner ring 3 can be easily disassembled.

  That is, the same effect as that of the first embodiment can be obtained.

It is a fragmentary sectional view of the constant velocity joint which shows Embodiment 1 of this invention. It is the A section enlarged view of FIG. It is sectional drawing which shows the state before an assembly of the shaft and inner ring of FIG.
