Sugar Scoop
Each sugar scoop includes the coupling for the motor
and the coupling guard. The coupling guard must be
mounted when the machine is in use. NORD's standard
supplied coupling is the jaw type. Make sure the set
screw is tighten after coupling is in place. The coupling
hub or sprocket should be mounted per Figure 2.
Motor Installation Instructions
1.
Make sure that the motor shaft is clean
2.
Mount the coupling onto the motor. Place the coupling so that the inside face is flush with the end of the motor shaft (see Figure 2). The
coupling should be heated prior to assembly, generally 250qF to 300qF (120qC to 150qC). *DO NOT HEAT THE URETHANE SPIDER.
Once in place, tighten the setscrew into the motor shaft to lock coupling in place.
3.
Let the coupling cool down before mounting the spider into the jaws. The spider should not be under axial compression when installed.
4.
Place the motor onto the scoop and engage the couplings together. The scoop has slotted holes for axial alignment.
**The motor and input shaft must be aligned in all directions to assure proper operation of the system.
5.
Before tightening the motor feet down, check the coupling alignment with a straight edge or a level. Maximum parallel misalignment
should not exceed 0.015" and angular misalignment should be held to 1.5q. Shim the motor feet to align the couplings. Careful
alignment extends the life of not only the coupling but all the components of the drive train.
6.
Once aligned, tighten the bolts on the feet to the scoop. Check the coupling alignment again due to compression of the shims.
7.
Mount the supplied coupling guard to the scoop.
8.
After a period of operation, recheck alignment and adjust as required.
