Right-Angle Gearheads bAdditional Informationb Technical reference ➜ Page F-1 Right-angle gearheads are flange-mounted gearheads that use worm gears and special helical gears. They allow motors to be installed at right angles to the axis of equipment such as belt conveyors. They are available in hollow shaft RH and solid shaft RA types and are ideal for keeping equipment compact. ˾Features b Ideal for Space-Saving Solution The output shaft is perpendicular to the motor shaft, so the motor can be installed perpendicularly to the axis being driven, enabling space-saving. A wide variety of gear ratios (20 types, from 3 to 180) are available. The optimum gear ratio can be selected as the same with ordinary gearheads. The maximum permissible torques are also the same as for ordinary gearheads. b Solid shaft of GE pinion gearheads come with a tapped hole at the tip of the shaft. Right-Angle Gearheads conform to the RoHS Directive that prohibits the use of six chemical substances including lead and cadmium. b Details of RoHS Directive ➜ Page G-23 93 mm 5IK90GE-CW2E motor and gearhead with a gear ratio of 1:18 Hollow shaft gearheads allow additional space savings and simpler mechanism designs due to the removal of some parts of mechanism as they do not require couplings for mounting. ˾Applicable Products The right-angle gearheads can be used with pinion shaft type motors listed below. Applicable Products Series Induction Motors World K Series Reversible Motors World K Series Electromagnetic Brake Motors World K Series US Series Speed Control Motors ES02 ϩ World K Series Speed Control Motors Inverter FE100 ϩ World K Series Induction Motors b The right-angle gearheads cannot be used with torque motors.
