TABLE 2
1.
Insert the taper lock bushing into the Coupling Hub (Item 4)
(See Figure 2).
2.
Slide the Coupling Hub (Item 4) with the customer supplied
taper lock bushing and key onto one shaft, then install the set
screws provided with the taper lock bushing (See Figure 2).
NOTE
Make sure there are no burrs on the shafts or keys.
NOTE
Do not tighten the set screws provided with the taper
lock bushing at this time.
3.
Using the Socket Head Cap Screws (Item 2), attach the
Coupling Adapter (Item 1) to the Clutch or Torque Limiter
(See Figure 2).
4.
Tighten the Socket Head Cap Screws (Item 2) to the
recommended torque (See Table 2).
5.
Slide the Coupling Adapter with the Clutch or Torque Limiter
onto the other shaft (See Figure 2).
6.
Tighten the taper lock bushing set screws to the recommended
torque.
7.
Adjust the hub separation to within the limits for parallel and
angular misalignment (See Table 2).
NOTE
For best results, Nexen recommends the use of a dial
indicator when checking the limits for parallel and
angular misalignment. To ensure accurate readings,
always rotate the hub on which the dial indicator
probe is mounted.
CAUTION
Coupling and shaft alignment should be checked
periodically, due to equipment shifting, etc. Alignment
should be rechecked after the first forty hours of
operation.
8.
Secure the Clutch or Torque Limiter with the Coupling
Adapter to the shaft according to the instructions provided
with the Clutch or Torque Limiter.
