Embodiment Construction

[0040] For the following description, it is emphasized that the invention is not limited to the embodiments, and thus not to all or more features of the described combination of features, but to each individual sub-feature of any / every embodiment. When separated from all sub-features described together, whether alone or in combination with any feature of another embodiment, it has the meaning of the object of the present invention.

[0041] figure 1 is a schematic view showing an exemplary application of a small or micro drive 1 with a connected transmission 3 for driving a driven shaft 7 of the transmission 3 shown in dotted line Application piece 5. The transmission 3 can in particular be designed as a planetary gear and comprise a corresponding, not shown, transmission mechanism which is preferably arranged in the transmission housing 9 . The driven shaft 7 is mounted, in particular by means of two driven bearings 8 , and can be connected via a transmission mechanism to t...

Abstract

A transmission device (3) for an electric miniature drive or microdrive, has a transmission housing (9)in which a transmission mechnical device is arranged, an attachment flange (13) for attaching the transmission device (3) to an application or load, a driven shaft (7), supported in at least one driven bearing (8) and used for driving the application, wherein the driven shaft (7) is connectable via the transmission mechanism to the miniature drive or microdrive; and a torque measuring member (15) for the registration of the torque generated on the driven shaft (7) by using a flexible element during operation of the miniature drive or microdrive. A magnetic encoder system (19) is disposed on the flexible element (17), which has the magnetic field generating and measuring elements (23, 25) for measuring a rotatory displacement of the flexible element (17). The flexible element (17) is disposed axially between the transmission mechanism and the attachment flange (13).

Description

technical field [0001] The invention relates to a transmission for small or micro electric drives, comprising: a transmission housing in which a transmission mechanism is arranged; a fixing flange for fixing the transmission on an application part; supported on A driven shaft in at least one driven bearing for driving the application part, wherein the driven shaft is configured to be connectable to a small or micro drive via a transmission mechanism; and a torque measuring member for The element detects the torque that occurs on the driven shaft during operation of the small or micro drive. Background technique [0002] A small or micro drive within the meaning of the invention is an electric drive with a maximum continuous power of 1000 W. [0003] Gearing for electric small or micro drives in which the number of driven revolutions (Abtriebsdrehzahl) is reduced by a reduction ratio At the same time, in particular the torque generated by the electric motor at the transmis...
