  • Patent number: 11598656
    Abstract: An encoder (10) for determining an angular position, the encoder (10) comprising a shaft (14, 16), a housing (18) and a transition region (32), the shaft (14, 16) projecting outwards from the housing (18) into the transition region (32), a measuring element (20) connected to the shaft (14), a sensor (22) for detecting the measuring element (20), and a control and evaluation unit (28) for generating, from the signals of the sensor (22), an angle signal in dependence on the angular position of the measuring element (20), wherein a protective cap (34) is arranged in the transition region (32) for protection against fluids (12) directed with pressure onto the transition region (32).

  • Patent number: 7638960
    Abstract: A positioning device for positioning a positioning element has a motor (18) that drives the positioning element (10) and has a measuring device that directly measures the positioning travel of the positioning element for controlling the motor (18). For this, a traction cable (32) is joined to the positioning element and is wound onto a drum (36). For measuring the positioning travel of the positioning element, the rotational position of the drum (36) is measured by means of an encoder (42).

  • Patent number: 7540095
    Abstract: A rotary position transducer has a housing, a rotor, which is connected to a drive shaft to be measured and projects into the housing so as to rotate with it and the angular position of which within one revolution is measured, and a multi-turn unit that is mounted in the housing and measures the number of revolutions of the rotor. The multi-turn unit is coupled with the rotor by way of a gear wheel gear mechanism, which has a driving spur wheel (10) connected to the rotor, and a driven spur wheel (12) of the multi-turn unit. In the case of one of the spur wheels (10), the head of every second tooth (16) is shortened up to the reference circle. In the case of the other spur wheel (12), the base of every second gap (18) between teeth is filled up to the reference circle. The spur wheels (10, 12) are helical-geared, wherein the modulus and the helix angle (?) of the helical gearing are determined in such a manner that at least one tooth (16) is always in engagement.

  • Publication number: 20080054765
    Abstract: An encoder for recording measured values, which depend on the rotating angle between a shaft (12) and a housing (10) containing the shaft (12), exhibits a stator (20) which is secured to the housing (10), a rotor (30) which is secured to the shaft (12), and a scanner which records the rotation of the rotor (30) relative to the stator (20). An elastic ring (42) with supporting points (44) rests on the circumference of the stator (20). In the mounting process the encoder is positioned on the shaft until the stator (20) is axially braced against the housing with the supporting points (44) of the elastic ring (42). In this auxiliary position the rotor (30) is fixed in position on the shaft. Then the stator is pressed against the housing while working against the force of the elastic ring (42) and is secured to the housing.
