General Flexibility

CbN helical gearmotors and speed reducers incorporate thelatest in design and manufacturing technologies to deliver an energy efficient, helical, gear train combined with either a constant or variable speed motor. This latest generation of CbN inline gearing is 98 percent efficient per gear stage and boasts total efficiency improvements over previous designs by delivering up to 40 percent more total speed reduction without added gear stages. Improvements in CbN designs begin with the expansion of flange mounting options available. Three phase motor designs now incorporate an upgraded wire and varnish treatment called Allguard, making many of them suitable for inverter applications. C-Face inputs utilize a compact quill design with a non-metallic liner and metal key to eliminate fretting corrosion while delivering a compact length. Each housing can be oriented in different mounting positions by a minor adjustment in oil volume and relocation of breather/drain locations. Varidyne inverter duty motor designs deliver up to 10:1 constant torque speed range gearmotors off-the-shelf.

Housing

One-piece housings replace the classical two-piece designs to improve alignment and overhung load integrity in the mostdemanding applications. Extremely compact envelopes providelow profiles and the footprint to directly interchange with older CbN products for simple aftermarket replacements. All housings are cast, with frames made with high strength cast iron (frame 0 is aluminum). Motor interfaces are generally shorter than previous CbN designs.

Gearmotors

A diverse array of different motor constructions and voltages in three and single phase are stocked to meet most industry and user specifications. This now includes IntelliGear, variable speed, TEFC gearmotors, incorporating a rugged, compact, pre-programmed AC controller onboard for simple 6:1 constant torque speed ranges. Optional speed range of 10:1 and 15:1 are available.

Performance

These CbN designs deliver up to 35 percent more capacity than previous CbN products in equivalent frames. For replacements, this means longer life. For new applications, this means cost savings through possible downsizing. Each CbN unit is factory filled with synthetic lubricant, ready to operate in a wide band of ambient temperatures with minimal in-service maintenance.

Reliability

Gear housings 1 to 5 are fitted with normally closed breathers, excluding outside contaminants and preserving low internal operating pressure. All oil seals operate on plunge ground shaft surfaces to deliver extended life. Enhanced insulating materials and other standard features of our Varidyne Inverter duty motors carry a 3 year warranty when operating with PWM inverter power up to 575 VAC. 33
