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 models and are ideal for keeping equipment compact. Features Right angle gearheads with mounting sizes of 0 mm (for W) or 0 mm (for 40 W) are available for GN pinion and mounting sizes of 0 mm (for or 0 W) are available for GU pinion. They can be connected to all Oriental Motor AC motors with the exception of BH, FBL, HBL, FPW series. The output shaft is perpendicular to the motor shaft, so the motor can be installed perpendicular to the axis being driven. Eleven available models span gear ratios are available from to 0,offering tremendous selection. The optimum gear ratio can be selected just as with ordinary gearheads. The maximum permissible torques are also the same as for ordinary gearheads. Hollow shaft gearheads allow additional space savings and simpler mechanism designs since they do not require couplings for mounting. Usually, hollow shaft gearheads are locked with a torque arm when mounted so the gearhead does not rotate from the reactive force of the load. When mounted with a torque arm, no centering is needed, so it is faster to mount the gearhead on the device.

Enter the gear ratio in the box () within the model name. Note : Unlike most worm gear mechanisms, the right-angle gear does not have self-locking capabilities. Calculating permissible overhung load for hollow shaft models When the end of the shaft being driven is supported as in the figure below, calculate the permissible overhung load using the following equations. (This mechanism is the most demanding in terms of overhung load.).

For motor combinations not covered, use the efficiency value in the table below for your calculations. When making a selection, remember that the transfer efficiency at startup is lower than at the rated speed.

Hollow shafts are finished to an inner diameter tolerance of H and machined with a key groove for mounting the load shaft. The recommended tolerance for the load shaft is h7. Use the key provided with the product by fastening it to the shaft. Apply a coating of molybdenum disulfide or similar grease to the inner diameter of the load shaft to prevent binding. Recommended load shaft dimensions are shown below. Unit = mm Inner diameter of hollow-shaft [H] GNRH GURH Enter the gear ratio in the box () within the model name. Stepped-down shafts Straight load shafts Recommended load shaft diameter [h7] Note : If the bolt extends out more than 4 mm from the end of the hollow shaft, no safety cover can be installed. (RH model hollow shaft gearheads include safety covers.) A-4 ORIENTAL MOTOR GENERAL CATALOGUE

6 Gearmotor Torque Table The speed is calculated by dividing the motor s synchronous speed (0Hz: 0r/min) by the gear ratio. The actual speed is % less than the listed value, depending on the size of the load. The efficiency of the gear assembly at startup is lower than the rating, so output torque is lower. All output shafts rotate opposite to the direction of motor shaft rotation. 4IKGN-CWE / IK40GN-CWE / GNRH IKGU-CWE / 4GURH IK0GU-CWE / GNRH IKGN-CWE / IK40GN-CWE / GNRA IKGU-CWE / GURA IK0GU-CWE / GURA RKGN-CWE / RK40GN-CWE / GNRH RKGU-CWE / GURH RK0GU-CWE / GURH 4RKGN-CWE / RK40GN-CWE / GNRA RKGU-CWE / GURA RK0GU-CWE / GURA Standard AC Brake FBL AXU AXH HBL MSS W ES US Gearheads Linear Heads Water Tight FPW Brushless Motor and Driver AC Speed Control ORIENTAL MOTOR GENERAL CATALOGUE A-
