Problems solved by technology

However, this must be achieved at the expense of a static and / or dynamic deviation of the axis of rotation of the measuring gear from its ideal orientation, which would lead to non-negligible measuring errors in the case, for example, of the The permanent magnet in the gear is rotated relative to the Hall sensor associated with the permanent magnet instead of the provided axis of rotation about an axis deviating therefrom, or instead of a separately provided rotational movement about the provided rotation axis, it performs a relative movement relative to the permanent magnet. Additional relative motion to rotational motion

Embodiment Construction

[0016] as in figure 1 As can be seen in , the drive gear 1 formed on the outside on the carrier element 5 is rotatably mounted in the sensor housing 9 of the angle sensor. For this purpose, the carrier element 5 is held with a short neck extending further below the gear wheel in an annular receptacle 10 of the sensor housing 9 which is surplus to this short neck. Two measuring gearwheels 2 , 3 , which are likewise mounted rotatably in the sensor housing 9 on axes 11 , 12 aligned parallel to the axis of rotation of the drive gearwheel 1 , mesh with this drive gearwheel 1 .

[0017] The axes 11 , 12 for the measuring gears 2 , 3 are accommodated diametrically opposite each other via spring-elastically acting elements 13 , 14 in the annular receptacle 10 of the sensor housing 9 . The spring-elastically acting elements 13 , 14 are formed in the illustrated embodiment of the angle sensor by spring strips held in two axial slots 10 ′ present in the annular receptacle 10 . The spr...

Abstract

An angle sensor for sensing angular position of a rotatable shaft includes a drive gear, a measuring gear, and a sensor housing. The drive gear is connected to the shaft. The measuring gear is driven by the drive gear. The angular position of the shaft can be determined from an angular position of the measuring gear. The sensor housing has a bearing for the drive gear. The drive gear and the measuring gear are rotationally mounted about respective axes of rotation in the sensor housing with the drive gear being inside the bearing. The drive gear is forcibly pressed into a radial position inside the bearing by at least one spring.

Description

technical field [0001] The invention relates to an angle sensor for detecting the rotational position of a rotatable shaft, which has a drive gear connected to the shaft in a torque-transmitting manner and at least one measuring gear driven by the drive gear, wherein the drive gear and at least one The measuring gears are mounted in the sensor housing, and the angular position of the shaft can be ascertained from the angular position of the measuring gear(s). Background technique [0002] Known from DE 199 00 330 A1 is an angle sensor for detecting the rotational position of a rotatable shaft, which has a drive gear connected to the shaft in a torque-transmitting manner and at least one measuring gear driven directly by the drive gear, wherein the drive The gearwheel and at least one measuring gearwheel are supported in the sensor housing, and the angular position of the shaft can be ascertained from the angular position of the measuring gearwheel / measuring gearwheel. Both ...
