II-O. INSTALLATION WOOD'S SURE-FLEX
®
SPACER COUPLINGS
Sure-Flex flanges (outer metallic parts) and sleeves (inner elastomeric members) come in many sizes and types. All rubber sleeves (EPDM) and Neoprene) have
the same ratings for a given size and may be used interchangeably. Hytrel sleeves, however, has completely different ratings. Rubber sleeves must not be substituted
for Hytrel... or Hytrel for rubber. First, determine the size and type of components being used. Remove all components from their boxes, and loosely assemble the
coupling on any convenient surface. (Do not attempt to install the wire
ring
on the two-piece E or N sleeve at this time.)
1. Inspect all coupling components and remove any protective coatings or lubricants from bores, mating surfaces and fasteners. Remove any existing burrs, etc.
from the shaft
3. Slide one coupling flange onto each shaft, using snug-fitting keys.
4.Position the flanges on the shafts so that each shaft extends into each flange a minimum length equal to the shaft diameter. Tighten one flange in its final position.
Slide the other far enough away to install the sleeve. With a two-piece sleeve, do not move the wire ring to its final position; allow it to hang loosely in the groove
adjacent to the teeth, as shown.
4. Slide the loose flange on the shaft until the sleeve is completely seated in the teeth of each flange. Tighten all fasteners to the values given in Table 2.
Different coupling sleeves require different degrees of alignment precision. Locate the earing failure (0) Excessive coupling wear
