A connection () of a first () to a second () cylindrical component for the transfer of circumferential and axial forces. The first component () has locking elements () arranged on its circumference and at the end, the second component () has windows () associated with the locking elements (), and the first and second components () can be plugged one into the other at the ends to form a positive interlock between the locking elements () and the windows ().

Connection of a first component to a second cylindrical component and method for mounting of the first and second components

A process of manufacturing a component for a hydrodynamic machine in which the component comprises a base body ( ) and a plurality of blades ( ) which are to be installed on the base body ( ). The process comprises the steps of installing the plurality of blades ( ) on the base body ( ) by a shaped fitted connection with the base body ( ) by applying continuous pressure against the base body ( ) and using a prefabricated torus as the base body ( ). The prefabricated torus is pressed by a pressure roller ( ) against the plurality of blades ( ) while holding the plurality of blades ( ) in a device ( ) against the pressure of the pressure roller ( ). A component for a hydrodynamic machine, comprising a base body ( ) and a plurality blades ( ) installed by the inventive process, is also disclosed.

Fitting of blades in hydrodynamic machines

The invention concerns an apparatus for torque transmission and axial securing of a first ( ) and a second ( ) torque conducting component. The apparatus has the form of a ring shaped component ( ), which possesses along its circumference projections ( ) which are spaced from one another and which are insertable in such a manner in the spaces between projections ( ) of the second component ( ) which lies on a surface ( ) of the first component ( ), that the sides of the projections ( ) which face the surface ( ) of the first component ( ) can be affixed to the first component ( ).

Ring for transmitting torque and for axially securing two rotating components

The method for precise position assembling a planetary gear unit consisting of a planetary gear, a planet shaft, a bearing, two thrust washers and two guide washers, especially for use in a planetary transmission for an automatic transmission of a motor vehicle consists in that the planetary gear unit is inserted within mean position tolerance, aligned and braced in a tool which tool has two displaceable stamps and two jaws with indented rings which jaws surround the stamps forming a ring and can be displaced independently of the stamps. By closing the tool, the indented rings clamp the guide washers until a constant pressure is exerted against them. The stamps are pressed against the ends of the planet shaft until they are forged.

Method for assembling a planetary gear unit in a precise position

The method for producing a planet carrier for a planetary gear which has one spider shaft ( ) and two guide plates ( ) disposed parallel to each other consists in that the guide plates ( ) are produced as precision blanked parts and that each of two guide plates ( ) located upon the spider shaft ( ) are interconnected in one stroke in a pressing process via rivets ( ), that in the shoulders ( ) of the rivets ( ) provided with tappets ( ) annular projections ( ) are fashioned and that the tool ( ) of the press impinging on the guide plates ( ) in direction of the shoulders ( ) is provided with an annular projection ( ) adapted to the annular projection.

Method for producing a planet carrier

For producing stamped parts, especially plates, a method is proposed consisting of only two method steps. In a first method step the workpiece is fine blanked (,) inside a device (,) is then moved to a stamping stage (,) by means of transfer tongs (,) which are likewise housed in the device (,). The stamping stage (,) is also located inside the device (,). In a second method step, the inner and outer contours are stamped on the workpiece (,) in the stamping stage (,) in a manner such that the burrs produced on the workpiece (,) during the first step are removed.
