MOUNTING
Preassembly inspection
Prior to assembly ensure all parts are clean and free from foreign material and damage. Check individual measurement of
relevant parts (e.g. hub, shaft fit / clearance etc) to maintain application requirement.
Fitting of hub on shaft
The seals must be assembled on the shaft prior to mounting of hubs.
Lightly smear the seals with grease and remove lube plugs from each half.
Keyed fit assembly : adjust key as necessary. Dependant upon type of adjustement and to facil tate fitting, we recommend
uniform heating of the hub to about 100°C to 120°C. Secure the seal.
Shrink fit on smooth shaft : with an interference of 1,2 to 1,6 ‰.
Degrease all contact surfaces and remove plugs from holes provided for hydraulic dismantling.
Heat preferably in a furnace to 250°C assuming an ambient temperature of 20°C.
ALIGNMENT
Will be obtained by moving one of the machines to be coupled.
Align shafts within the misalignment limits given in table below.
For gap and angular alignment use a feeler gauge inserted between hub faces at four points, 90° apart, as shown in view below.
For parallel alignment, use a straight edge, located over four external points on the hubs (as shown).
Note : - For more accurate alignment use a dial indicator.
- Each shaft must have its own thrust bearing, the coupling allowing for its free positioning.
ASSEMBLY
Before inserting grid, hand pack grooves and gap with lubricant (refer to tables overleaf for recommendations on type and
quantity of lubricant). Fit grid over hubs and starting at one end, work coils of grid between the teeth. Seat with a soft mallet. If
grids are supplied in more than one segment, install so that all cut ends extend in the same direction. Hand pack more
lubricant around the assemble cover : see instructions overleaf.
