ABSTRACT:
The specification discloses a laser alignment head system for taking alignment data with respect to a pair of coupled shafts. Each alignment head includes a laser, a laser sensor for sensing a laser beam, an angle sensor for sensing the rotational orientation of the laser head, a computer and a transmitter for transmitting data from the laser head. The two laser heads are mounted on the two shafts in an opposing facing relationship with the laser beam of one head disposed on the laser sensor of the other head. As the shafts are rotated, the laser beam moves on the laser sensor and the laser sensor generates a position signal corresponding to such movement. Likewise, the angle sensor produces an angle signal corresponding to the rotational angle of the laser head as the shafts are rotated. The computer produces output data corresponding to the position signal and the rotational angle, and such data is transmitted to a receiver. An analyzer is interfaced with the receiver to receive the data and calculate misalignment information.
