IRA SYNCROGEAR WORM & WORM HELICAL GEARMOTORS & SPEED REDUCERS

 
bulletUtilize same motor end as Series 2000 Gearmotors
bulletFoot and flange mount worm and worm helical available.
bulletTorque range up to 3500 in.-lbs.
bulletInnovative self-locking taper shaft connection (motor to gear) allows on-site replacement without removing primary pinion, or disconnecting the load.  This ensures precision alignment and eliminates fretting to expedite motor removal.

 


SERIES 2000

Type CbN      

CbN in-line helical speed reducers and gearmotors are available in sizes 17 through 29 with output torque to 145,000 in. lbs. and numerous reduction ratios from .80 to 6300:1

 

 CbN speed reducers are available with the following inputs: C-face, input shaft, scoop mount and integral gearmotor. Gearheads are available in foot or flange mounted configurations.

Type OtN

OtN helical spiral bevel speed reducers and gearmotors come in a range of sizes, 23 through 28, with output torque up to 88,000 in. lbs. Reduction ratios are available from 12.5 to 7100:1.

 

OtN speed reducers have identical inputs as the CbN range. Output configurations include foot or flange mounted gearheads, single output shaft (right or left- hand), double output shaft or hollow shaft.
hollow shaft.

Type MbN

 MbN shaft-mounted speed reducers and gearmotors come in sizes 21 through 25 with output torque up to 32,000 in. Ibs. Nominal reduction ratios are 3 to 6300:1.

 

 MbN shaft mounted speed reducers are available in straight bore designs or with a unique tapered bushing which makes mounting and removal simple and minimizes fretting corrosion. Output configurations include hollow shaft or solid shaft. Flange mounted versions are also available. Inputs include C-face, input shaft, scoop mount and integral gearmotor.
