Method for producing a joint connection and joint connection
View Patent ↗A method for producing a joint connection for torque-transmitting connection of a component ( 1 ) provided with spur gear teeth ( 13 ) with a constant velocity joint ( 2 ) provided with corresponding spur gear teeth ( 11 ). The spur gear teeth can be brought into interengagement by applying an axial engaging force and have flanks ( 25 ) that contact each other as functional surfaces. The invention also relates to a joint connection of the aforementioned type.
1. A joint connection for connecting a component provided with axially facing spur gear teeth with a joint provided with corresponding axially facing spur gear teeth in a torque-transmitting manner, wherein:
said spur gear teeth on said component and on said joint have flanks that have a wedge angle in the range from about 10 to about 150 and that contact each other as functional surfaces;
said joint is a constant velocity joint having an inner hub comprising a cylindrical section, and the axially facing spur gear teeth of the joint are formed on an axial end face of the cylindrical section of the inner hub;
said component is provided with a sleeve having a cylindrical section and a set of longitudinal teeth formed on at least a partial area of an inner surface of said sleeve, said set of longitudinal teeth on said sleeve mating with a set of longitudinal teeth formed on at least a partial area of an outer surface of said component such that the sleeve is non-rotatably connected to said component, and the axially facing spur gear teeth of the component are formed on an axial end face of said cylindrical section of said sleeve;
said joint connection comprises a securing member which engages respective connection elements provided on the outer circumference of the cylindrical section of the sleeve and on the outer circumference of the cylindrical section of the inner hub of the joint and applies an axial engaging force to the sleeve and the joint to fix the flanks of the spur gear teeth on the sleeve in intermeshing, torque transmitting interengagement with the flanks of the spur gear teeth on the inner hub of the joint; and
said securing member comprises a securing nut with a thread which mates with a thread on the component and a shoulder which projects inwardly on a side of said securing nut facing said joint and engages a securing ring received in a groove formed in said cylindrical section of said inner hub.
2. A joint connection according to claim 1 , wherein the wedge angle of the functional surface flanks of the spur gear teeth is in the range from about 1.5° to about 5°.
3. A joint connection according to claim 1 , wherein the joint is an opposed path constant velocity joint.
4. A joint connection according to claim 1 , wherein the spur gear teeth are case hardened.
5. A joint connection according to claim 1 , wherein the spur gear teeth are heat treated or tempered.
