NRX   -       -N    

 with CORONET reducer  ● For NRX □ -11K to 18K-C □ , follow the procedure on page 13.

When reassembly of the speed change and reduction sections is complete after disassembly, adjust pressure contact 

force according to the following procedure.

When reassembling the speed change section, move the ring to the low speed end (output shaft) in advance.

● Procedure

(1) Put a rod (T-wrench) etc. into the ER flange adjustment hole, and align the ER flange and adjuster surfaces on the same level by turning the 

adjuster. After that, assemble the main units of the speed reduction and change sections.

(2) Remove the top cover in the speed change section, look into the inside, and adjust pressure contact force by turning the adjuster with a rod (T-wrench) 

etc. according to the following procedure.

(3) Check pressure contact force adjustment according to the tables below. 

(Turning the adjuster clockwise increases contact force, and turning counterclockwise decreases contact force when viewed from the output shaft)

After adjusting clearance to 0 to 0.1 mm, turn the 

adjuster by one pitch to increase contact force

(4) Hold the cam retainer with pliers, etc., and check that the total 

backlash is within the range of values in the table below.

If backlash is too large or small, turn the ER flange adjuster, and 

make adjustment.

(5) When shim (pressure contact force) adjustment is complete, secure the adjuster using the fixing bolt, and set the blind bolt on the other side.

Note : The fixing bolt is used to keep the adjuster from turning. Keep the tip of the bolt from coming into contact with the bottom of the adjuster.

(4) Look into the inside of the speed drive, and check that clearance 

between the cam disc and input cam is within the range of 

values in the table below.

If clearance is too large or small, turn the ER flange adjuster, 

and make adjustment.
