Belt Hog Specifications
Housing Material: Precision molded PA Dimensions: 2.68 x 3.62 x 2.65 in (h x w x d) Weight: approximately 1.66 lbs Battery type: (2) AA batteries Operating time: 20 hours continuous operation Measuring distance: 6" to 20 feet Measuring accuracy: Better than 0.5mm or 0.2 degrees Pulley diameter range: 3" and larger Pulley belt groove with: A, B, C, D, and E sizes (0.2" - 1.6") Classification: Class 2 LASER Output power: <1mW LASER wavelength: 630 - 675 nm Belt Hog Alignment Procedure The Belt Hog uses two LASER transmitter for projecting of LASER lines on the opposite LASER unit. By adjusting the pulleys so that the laserline coincides with the reference line on the opposite LASER unit, the pulleys are aligned. Mounting of the Belt Hog units Each unit is mounted on the pulley as shown in the diagram below. Note: The magnets, which holds the unit to the pulley, are very strong. Do not pinch your fingers!
Position both units with the spring action probes resting in the same groove on both pulleys and the units are facing each other as shown below.
When the units are mounted, turn on the LASERS. Each LASER generates a line on the opposite unit. When correctly aligned the lines coincide with the reference marks on the labels on both units. If the belt transmission is mis-aligned, start by correcting the angular error.
It is important that the pulleys are mounted correctly on the shafts and that the shafts are straight before starting the alignment process. Wobbling or warped pulleys affects the alignment quality severely. Safety The Belt Hog uses LASER diodes with a power output of less than 1.0 mW. The LASER classification is Class 2, which is considered safe for its intended use with only minor precautions required. These are:
