Mounting and Dismounting: Torque Limiters SK

SKP
with key way

 Mounting:
Slide the coupling onto the shaft. Lock it in position, with an endplate (8) for example.		 Dismounting:
Remove the end plate and slide
the coupling off the shaft using
an appropriate tool.

SK1
with clamping hub
Series 1.5 - 10

 Mounting:
Slide the coupling onto the shaft to the proper axial position. Using a torque wrench tighten the clamp screw to the proper tightening torque as indicated.
(see page of torque limiter SK1)		 Dismounting:
Simply loosen the clamp screw and remove the coupling.

SK1
with tapered
bushing

Mounting:
Slide the coupling onto the shaft to the proper axial position. Using a torque wrench, uniformly tighten the clamping screws using a cross-wise tightening pattern. Apply 1/3, 2/3 and full torque until all the clamping screws are evenly tightened to the correct tightening torque as given on page torque limiter SK1.

CAUTION: Further tightening of the clamping screws will damage the tapered bushing connection. While tightening the coupling may move slightly towards the tapered bushing.

 

 Dismounting:
Loosen the clamping screws.
Insert the three jack screws into the taped holes on the tapered segment apply even pressure to remove the tapered segment.
Remove the coupling.

SK2
with clamping
hub

Mounting:
Prior to mounting make sure that the shafts to be connected do not exceed the angular or lateral misalignment limits for the coupling. This data can be found in the catalog. Slide the coupling on the first shaft end to the proper axial position. Using a torque wrench, tighten the clamp screw to the correct tightening torque as indicated (page torque limiter SK2). Insert the second shaft into the other end of the coupling to the proper axial position. Make sure that the coupling is free of any axial forces before tightening. Tighten the clamp screw as above using a torque wrench.

 

 Dismounting:
Simply loosen the clamp screw and remove the coupling.

SK3
with tapered
bushing

Mounting:
Prior to mounting make sure that the shafts to be connected do not exceed the angular or lateral misalignment limits for the coupling. This data can be found in the catalog. Slide the coupling onto the first shaft to the proper axial position.
Using a torque wrench, uniformly tighten the clamping screws using a cross-wise tightening pattern. Apply 1/3, 2/3 and full torque until all the clamping screws are evenly tightened to the correct tightening torque (page torque limiter SK3).

CAUTION: Mounting is completed. Further tightening of the clamp screws may damage the tapered bushing connection.

 

 Dismounting:
Loosen the clamping screws.
Use the three jack screws 9 conveniently mounted in the taper segment and 10 on the bellow body to evenly back out the tapered segment. Remove the coupling.

SK5
with press-fit
tapered
clamping hubs

 Mounting:
Prior to mounting it is necessary to consider the overall length of the assembled coupling. The press-fit coupling requires a specific pretensioning (K) between the two coupling halves to ensure backlash free operation. Mount the „female” coupling half containing the bellow onto the first shaft end to the proper axial position. Using a torque wrench tighten the clamp screw to the proper tightening torque. Mount the „male” coupling segment onto the second shaft end. The proper axial position is when the two couplings come together and coupling is compressed by the proper pre-tension distance (K) (see page torque limiter SK5). When the coupling segment is properly positioned tighten the clamp screw to the proper torque.		 Dismounting:
Pull the coupling apart. Simply
loosen the clamp screws and remove the coupling from the shaft.
