10.3  Changing the elastic intermediate ring 

 

Injury hazard! 

 

Switch-off the drive before all work on the coupling! 

 

Secure the drive against unintentional switching on and rotating! 

• 

Pull back a shaft with mounted

coupling hub (Figure 10, Pos. 1).

• 

Remove the intermediate ring

(Figure 10, Pos. 2).

• 

For easier mounting, the new

intermediate ring can be provided

with a slip additive before introduc-

tion (e.g. Talcum)

• 

insert a new intermediate ring

• 

Push the coupling halves together

again.

• 

Adjust the coupling according to the

following specifications in “8 Cou-

pling adjustment".

Warning! 

 

Before commissioning the plant, install all protective devices 
against unintentional touching of free rotating parts.  

 

To avoid sparks coverings in stainless steel should be used. 

 

The coverings must fulfil at least the demands of protection type 
IP2X. 

 

The covering is to be so designed that it does not deposit dust 
onto the coupling parts. 

 

The covering must not touch the coupling or influence it in its 
function. 

When using accessories and spare parts which were not originally manufactured by 

RINGFEDER POWER TRANSMISSION

, no liability or guarantee for any damages 

will be accepted. 

11  Waste Disposal 

The waste disposal has to occur according to the specific regulations of the respective user 

country.
