Problems solved by technology
[0007] In addition, there is a higher assembly cost due to the gluing of the magnets on the code carrier arranged outside the gear structure, which increases the height of the structure and is associated with the risk of loss if the adhesive fails in the event of a longer service life. Time
[0008] Furthermore, the pasting process has a certain gap which cannot be minimized due to machine handling

Embodiment Construction
[0084] exist Figures 1 to 3 A multi-turn rotary encoder 1 is shown, which essentially consists of an upper reduction gear 2, the carrier plate 12 of which consists of a plastic material.
[0085] In another design, it can also be provided that the carrier plate 12 consists of a light metal die-cast material.
[0086] The reduction gear 2 has a central groove 3 through which the free end of the shaft 4 projects, the angle of rotation of which is to be detected by a multi-turn rotary encoder.
[0087] The carrier board 12 is supported at the bottom surface of the carrier board 12 opposite the underlying circuit board 7 by means of axial tabs 5 arranged uniformly distributed over the periphery and at the periphery with supports 6 in between, which The carrier board is supported at the top surface of the circuit board 7 .
[0088] The housing 9 , which preferably consists of a metallic material, is of annular design and has an upwardly directed annular flange 8 a which continue...

Multi-turn angle measuring device for multiple rotations of a measuring shaft (4) consisting of a first code carrier (31) with an optical single-turn scanning (34) for detecting the absolute position of the shaft and for measuring the shaft ( 4) The second code carrier of the number of rotations constitutes, wherein, between the first code carrier (31) and the second code carrier, a reduction gear (2) is arranged, and the second code carrier is composed of several permanent magnets (22 ) whose position is detected by an assembly of Hall sensors (16a‑16c) fixed to the housing, wherein correspondingly permanent magnets (22) are embedded in the plastic of the transmission gear (20) of the reduction transmission (2) in the material.
Description
[0001] Field of Invention [0002] The invention relates to a multi-turn angle measuring device for measuring multiple rotations of a shaft, wherein the invention is based on a multi-turn angle measuring device with single-turn detection on the optical path and multi-turn detection by magnetic scanning . Background technique [0003] The present invention is based on EP 1 391 696 A2, in which a multi-turn angle measuring device with optical single-turn scanning and magnetic multi-turn scanning is described. [0004] The disadvantage of this known multi-turn angle measuring device is the use of a complex and backlash reduction gear, which uses a worm gear which interacts with the rest of the gear wheel with a large backlash, so that only the belt Insufficient multi-turn angle scans with correspondingly faster wear of the transmission. [0005] Another disadvantage is the fixation of the permanent magnets in the transmission structure, which results in a less compact structure...
