Abstract
A flexible transmission element (1) which can be used, in particular in a harmonic drive (9) and which includes a sleeve-shaped, outer toothed section (3) and a flange (4) connected to this section (3), the outer toothing (8) of the sleeve-shaped section (3) is sheet metal toothing formed in a die.
Claims14
A flexible transmission element, comprising:
- a sleeve-shaped, outer toothed section having outer toothing, the outer toothing is formed sheet-metal toothing;
- a flange connected to said sleeve-shaped, outer toothed section, the flange including multiple openings;
- and
- at least one of the openings has an elongated, concavely curved shape with respect to a center axis of the transmission element.

A method for producing a flexible transmission element, comprising the following steps:
- preparing an unprocessed part, which has a sleeve-shaped section with a radially inwardly directed thicker section,
- pressing material located in the thicker section radially outwardly into an inner-toothed die, and
- forming outer toothing of the transmission element.
A flexible transmission element, comprising:
- a hat-shaped, deep drawn sheet-metal part including a sleeve-shaped section and a radially extending flange located at one axial end;
- outer toothing integrally formed on an opposite end of the sleeve-shaped section from the radially extending flange;
- a first plurality of fastener openings in the radially extending flange;
- and
- a second plurality of flex openings in the radially extending flange, the flex openings each having an elongated, concavely curved shape with respect to a center axis of the transmission element.
