Definitions

  • the present invention relates to a clutch gear manufacturing apparatus and a clutch gear manufacturing method as defined in the preamble of claims 1 and 8.
  • the position of the workpiece is aligned with a die to prevent an excessive force to act on the workpiece. Accordingly, the shapes of the reverse tapers can be accurately formed.
  • a clutch gear used for a multi-cone synchronizer is necessary to have a cone hole which allows a claw portion of a middle cone to be engaged so as to synchronously rotate the middle cone, the middle cone being arranged between an inner cone and an outer cone.
  • the cone hole is typically formed by machining after the reverse tapers are formed, or by forging or the like before the reverse tapers are formed (For example, see Japanese Examined Patent Application Publication No. 6-98451 as the closest prior art).
  • the cone hole is formed by machining after the reverse tapers are formed, the number of manufacturing steps is increased, and hence, the manufacturing procedure may become troublesome. Also, when the cone hole is formed by forging or the like before the reverse tapers are formed, the cone hole may be deformed through the formation of the reverse tapers.
  • a clutch gear manufacturing apparatus and a clutch gear manufacturing method according to the present invention employ the following configurations.
  • a clutch gear manufacturing apparatus for manufacturing a clutch gear used for a multi-cone synchronizer.
  • the apparatus includes the features of claim 1.
  • the cone hole is formed when the clutch gear primary product is pressed down by the punch and the spline teeth are being pressed by the blade.
  • the shapes of the reverse tapers can be prevented from being deformed through the formation of the cone hole.
  • the step of forming the reverse tapers at the spline teeth and the step of forming the cone hole in the side surface of the clutch gear primary product can be performed by a single apparatus. As a result, the clutch gear used for the multi-cone synchronizer can be accurately manufactured while the number of manufacturing steps is reduced.
  • the punch may have a cylindrical shape with an outer diameter substantially equivalent to a tip diameter of the blade. Accordingly, positioning of the punch and the die can be directly performed. As a result, variation in dimensions can be reduced as compared with a case where positioning is performed in an additional step with a guide rod or the like. Thus, positioning can be further accurately performed.
  • the knockout sleeve may be configured to hold the clutch gear primary product between the knockout sleeve and the punch with a predetermined pressure when the knockout sleeve receives the clutch gear primary product. Accordingly, since the spline teeth can be reverse-tapered while the clutch gear primary product is held between the knockout sleeve and the punch, the clutch gear can be accurately manufactured. In addition, bulged portions or burr generated at the side surface of the clutch gear, for example, bulged portions generated near the roots of the spline teeth can be reliably crushed and eliminated.
  • the knockout sleeve may be configured to contact the clutch gear primary product and have a diameter substantially equivalent to the tip diameter of the reverse taper teeth of the die. Accordingly, the knockout sleeve can stably receive the clutch gear primary product, and hence, the clutch gear can be accurately manufactured. In addition, bulged portions or the like generated near the roots of the spline teeth can be reliably crushed and eliminated.
  • the knockout sleeve may be configured to receive the clutch gear primary product so that the clutch gear primary product is pressed down while the clutch gear primary product is held between the knockout sleeve and the punch. Accordingly, the clutch gear primary product can be stably pressed down. As a result, the clutch gear can be accurately manufactured.
  • the knockout sleeve may have an insertion hole that allows the punch pin to be inserted. Accordingly, the cone hole can be formed by inserting the punch pin into the insertion hole. In addition, a waste after punching can be eliminated through the insertion hole.
  • the punch pin may be vertically movably arranged in the punch. Accordingly, the apparatus can become compact.
  • a clutch gear manufacturing method manufactures a clutch gear used for a multi-cone synchronizer.
  • the method includes the steps as defined in claim 8.
  • the cone hole is formed by the punch pin when the clutch gear primary product is pressed down by the punch and the spline teeth are being pressed by the blade.
  • the shapes of the reverse tapers can be prevented from being deformed through the formation of the cone hole.
  • the step of forming the reverse tapers at the spline teeth and the step of forming the cone hole in the side surface of the clutch gear primary product can be performed by a single apparatus. As a result, the clutch gear used for the multi-cone synchronizer can be accurately manufactured while the number of manufacturing steps is reduced.
  • the step (c) may be pressing down the clutch gear primary product by the punch which has a cylindrical shape with an outer diameter substantially equivalent to a tip diameter of the blade. Accordingly, positioning of the punch and the die can be directly performed. As a result, variation in dimensions can be reduced as compared with a case where positioning is performed in an additional step with a guide rod or the like. Thus, positioning can be further accurately performed.
  • the step (c) may be pressing down the clutch gear primary product while the clutch gear primary product is held between the knockout sleeve and the punch. Accordingly, the clutch gear primary product can be stably pressed down. As a result, the clutch gear can be accurately manufactured.
  • the step (c) may be holding the clutch gear primary product between the knockout sleeve and the punch with a predetermined pressure when the knockout sleeve receives the clutch gear primary product. Accordingly, bulged portions or the like, which are generated near the roots of the spline teeth in the side surface of the clutch gear primary product though the formation of the spline teeth, can be crushed and eliminated.
  • the step (d) may be receiving the clutch gear primary product by the knockout sleeve which has a diameter substantially equivalent to the tip diameter of the blade. Accordingly, the knockout sleeve can stably receive the clutch gear primary product. Also, bulged portions or the like, which are generated near the roots of the spline teeth can be reliably crushed and eliminated.
