Patent number: 8633685Abstract: The invention concerns a system for measuring the alignment error of two axles provided with a first and a second coupling part by means of a biaxial orthogonal magnetic sensor system comprising a sensor and a magnet, wherein said sensor is designed to be placed on the first coupling part with its one direction of sensing oriented in one direction of magnetization of said magnet, which magnet is designed to be placed on the other coupling part and means for reading off an angle error and offset error independently of each other during the rotation of the axles on-line. The system moreover includes a reference sensor for determining said angle error and offset error orientation relative to a known direction.Type: GrantFiled: July 17, 2008Date of Patent: January 21, 2014Assignee: Elos Fixturlaser ABInventors: Jan Wipenmyr, Christer Johansson, Christian Jonasson

Patent number: 8533965Abstract: The invention relates to a device (1) for measuring and alignment of a first component (2, 4) and a second component (3, 5) in relation to each other, where the device comprises a first detector unit (6) disposed to be mounted on the first component (2, 4) and a second detector unit (7) disposed to be mounted on the second component (3, 5) as well as a control unit (12) which is connected to the first detector unit (6) and the second detector unit (7). The device (1) comprises a first geometric pattern (16) disposed on the first detector unit (6) and a second geometric pattern disposed on the second detector unit (7). The position of the first geometric pattern (16) can be detected by the second detector unit (7) and the position of the second geometric pattern can be detected by the first detector unit (6). The invention also relates to a method for aligning a first component (2, 4) and a second component (3, 5).Type: GrantFiled: October 8, 2009Date of Patent: September 17, 2013Assignee: Elos Fixturlaser ABInventor: Peter Strömberg

Publication number: 20130154619Abstract: The present invention relates to a system (S) for measuring the position of a coupling member (1) that comprises a shaft part (2), a first flange (3), a second flange (4) and a first resilient bushing (5), which secures the first flange (3) to the shaft part (2), and a second resilient bushing (6), which secures the second flange (4) to the shaft part (2). Each resilient bushing (5, 6) is arranged with a resilient yield between the respective flange (3, 4) and the shaft part (2). The flanges (3, 4) are intended to be secured to a respective first shaft (7) and second shaft (8). When the coupling member (1) is placed between the first shaft (7) and the second shaft (8), it is intended to transfer a rotation movement from the first shaft (7) to the second shaft (8).Type: ApplicationFiled: June 30, 2011Publication date: June 20, 2013Applicant: ELOS FIXTURLASER ABInventors: Clas Kron, Peter Sandstrom, Peter Stromberg
