Payload Mounting– LCR22/30
Payload mounting to LCR using the M3 x0.5 (LCR30) M2.0 x 0.4 (LCR22 ) in the load plate. When fastening to load
take precaution in using screws with no more than 5.5mm of thread engagement, as to not damage positioner.
The LCR30 contains 2.5 diameter H7 (slip fit) dowel holes for repeatable mounting to customer load plate if desired.
See pages 10 thru 13 for detailed carriage specifications.
WARNING : To avoid damage to nut - carriage assembly
Do not back drive (push by hand) the carriage. Carriage should be only moved by input to the
drive shaft via motor or hand crank.
Moment loading pre - cautions
:
The LCR positioners have rated individual moment and load ratings. When multiple
moments are applied to carriage these rating must be reduced use the equation below as a guideline.
MOMENT LCR22 SQ RAIL/BUSHING LCR30 SQ RAIL/BUSHING
Mroll (N - M) 0.9/0.1 2.6/0.3
Mpitch (N - M) 2.5/0.8 8.2/1.5
Myaw (N - M) 2.0/0.3 6.5/0..8
Moment Factor:
Take each existing moment/ corresponding maximum allowable moment = moment factor.
Sum all the moment factors and result must be less than 1.8
Example : LCR30 screw drive sq rail version with the following:
Mroll =0.5 N - m = 0/2.6 (0.00)
Mpitch =2.5 N - m = 2.5/8.2 (0.30)
Myaw =1.0 N - m =1.0/6.5 (0.15)
SUM THE ABOVE=(0.00+0.30+0.15)=0.45 WHICH IS LESS THAN 1.8
Moment loading is acceptable.
