Balancing - Siemens Flender FLUDEX 4600 Series Operating Instructions Manual

6.1.5

Balancing

FLUDEX couplings are delivered balanced.
Prebored N­EUPEX add­on couplings are delivered unbalanced. It is recommended that these parts are
balanced to suit the application after finish­boring (see DIN ISO 1940 and DIN 740/2), minimum balancing
quality G16.
Balancing is normally done by drilling material away.
If one­level balancing is required on brake disk / brake drum (13; 32), the material on the front end at the
disk's bottom is to be removed. When two­level balancing, the brake drum (13) should be balanced
together with part 3, and part 5 with part 8.
With one­level balancing, on part 1 material must be removed from between the webs,
the bottom must however not be drilled right through.
On part 4 and part 9 the material must be removed from the end face between the cams.
Sufficient space must be left between the balancing hole and the cam to avoid
weakening the cam connection.
On part 13 / 32 the brake surface must not under any circumstances be damaged.
Since the coupling part 3, the cam part, is always in a balanced condition, the coupling part 2 can be
balanced individually or together with the fitted part 3.
Finish­bored couplings and/or coupling parts are balanced according to the customer's specifications.
