Rotation of the servo motor is transmitted through the input gear to the spur gears, and the speed is reduced accordingly with the gear ratio between the input gear and the spur gears <Fig. 1>.

Since they are directly connected, the crankshafts have the same rotational speed as the spur gears <Fig. 1>.

Two RV gears are mounted around the needle bearings on the eccentric region of the crankshaft. (In order to balance the equal amount of force, two RV gears are mounted) <Fig. 2>.

When the crankshafts rotate, the two RV gears mounted on the eccentric sections also revolve eccentrically around the input axis (crank movement) <Fig. 2>.

Pins are arrayed in a constant pitch in the grooves inside the case. The number of pins is just one larger than the number of RV teeth <Fig. 3>.

As the crankshafts revolve one complete rotation, the RV gears revolve eccentrically one pitch of a pin (crank movement), with all the RV teeth in contact with all of the pins <Fig. 3>.

The rotation is then output to the shaft (output shaft) via the crankshaft so that the crankshaft rotation speed can be reduced in proportion to the number of pins <Fig. 3>.

The total reduction ratio is the product of the first reduction ratio multiplied by the second reduction ratio.

Principle of Operation

Rotation of the servo motor is transmitted through the input gear to the large center gear, and is then transmitted through the small center gear to the spur gear. At this point, the speed is reduced accordingly to the gear ratio between the small center gear and the spur gear. This operation is carried out in the First reduction section <Fig. 1>.

Since they are directly connected, the crankshafts have the same rotational speed as the spur gears <Fig. 1>.

Two RV gears are mounted around the needle bearings on the eccentric region of the crankshaft. (In order to balance the equal amount of force, two RV gears are mounted) <Fig. 2>.

When the crankshafts rotate, the two RV gears mounted on the eccentric sections also revolve eccentrically around the input axis (crank movement) <Fig. 2>.

Pins are arrayed in a constant pitch in the grooves inside the case. The number of pins is just one larger than the number of RV teeth <Fig. 3>.

As the crankshafts revolve one complete rotation, the RV gears revolve eccentrically one pitch of a pin (crank movement), with all the RV teeth in contact with all of the pins <Fig. 3>.

The rotation is then output to the shaft (output shaft) via the crankshaft so that the crankshaft rotation speed can be reduced in proportion to the number of pins <Fig. 3>.

The total reduction ratio is the product of the first reduction ratio multiplied by the second reduction ratio.

Life Rating The lifetime resulting from the operation with the rated torque and the rated output speed is referred to as the “life rating ”.

Allowable Acceleration/Deceleration TorqueWhen the machine starts or stops, the load torque to be applied to the reduction gear is larger than the constant-speed load torque due to the effect of the inertia torque of the rotating part. In such a situation, the allowable torque during acceleration/deceleration is referred to as “allowable acceleration/deceleration torque”.Note: Be careful that the load torque, which is applied during normal

operation, does not exceed the allowable acceleration/deceleration torque.

Momentary Maximum Allowable TorqueA large torque may be applied to the reduction gear due to execution of emergency stop or by an external shock. In such a situation, the allowable value of the momentary applied torque is referred to as “momentary maximum allowable torque”.Note: Be careful that the momentary excessive torque does not

exceed the momentary maximum allowable torque.

Allowable Moment and Maximum Thrust LoadThe external load moment may be applied to the reduction gear during normal operation. In such a situation, the allowable values of the external moment and the external axial load are respectively referred to as “allowable moment” and “maximum axial load”.

MC : Load moment (N-m)W1, W2 : Load (N)L1, L2 : Distance to the point of load application (mm)α : Designated dimension (mm) (Refer to the Rating Table.)

Note: When the load moment and the axial load are applied concurrently, ensure that the reduction gear is used within the corresponding allowable moment range, which is indicated in the diagram on the next page.

W1 x (L1 + α) + W2 x L2MC = 1000

Momentary Maximum Allowable MomentA large moment may be applied to the reduction gear due to execution of emergency stop or by an external shock. In such a situation, the allowable value of the momentary applied moment is referred to as “momentary maximum allowable moment”.Note: Be careful that the momentary excessive moment does not

exceed the momentary maximum allowable moment.

Allowable Output Speed [Continuous]The allowable output speed when the machine starts and stops repeatedly is referred to as “allowable output speed [Continuous]”.Note: Maintain the environment and operation conditions so that the

temperature of the reduction gear case is 60˚C or lower.

Allowable Output Speed [Intermittent]The allowable output speed during the operation in which the reduction gear is not activated frequently is referred to as “allowable output speed [Intermittent]”.Note: Maintain the environment and operation conditions so that the

temperature of the reduction gear case is 60˚C or lower.

Torsional Rigidity, Lost Motion, BacklashWhen a torque is applied to the output shaft while the input shaft is fixed, torsion is generated according to the torque value and a hysteresis curve results.The value of b/a is referred to as “torsional rigidity”.The torsion angle at the mid point of the hysteresis curve width at ±3% of rated torque is referred to as “lost motion”.The torsion angles when the torque indicated by the hysteresis curve is zero are referred to as “backlash”.

Installation of the reduction gear and mounting it to the output shaft

<Bolt tightening torque and tightening force>

<Calculation of allowable transmission torque of bolts>

<Serrated lock washer External teeth for hexagonal socket bolt>

When installing the reduction gear and mounting it to the output shaft, use hexagon socket head cap screws and tighten to the torque, as specified below, in order to satisfy the momentary maximum allowable torque, which is noted in the rating table.Employment of the Belleville spring washer is recommended to prevent the bolt from loosening and protect the bolt seat surface from flaws.

Engineering Notes

Note: 1. The tightening torque values listed are for steel or cast iron material.2. If softer material, such as aluminum or stainless, is used, limit the tightening torque. Also pay attention to the system

requirements of the transmission torque.

Coupling Assembly

The clamp coupling is stored in a packing box.Note: Ensure that grease (Pyronoc Universal N6B) has been applied to the spline hole of the input shaft insertion opening. Without

grease, the spline may be damaged on fitting.

Wipe the outside of the motor shaft and the clamp surface with a rag.Note: If there is any foreign material or oil adhered to the outside of the motor shaft or the clamp surface of the clamp coupling

motor shaft, tight fitting will not be achieved.

Insert the motor shaft into the coupling until its tip comes into contact with the partition plate of the coupling.Note that you can easily insert the motor shaft at first, but will feel greater pressure while inserting it the last several millimeters.

Note: 1.If there is a keyway on the motor shaft, remove the key and align the center of the keyway with the keyed shaft mounting range of the coupling. Otherwise, a tight fitting will not be achieved.

2.Forceful insertion of the motor shaft may damage the coupling.3.If the motor shaft is not inserted up to the partition plate, the gear head may be damaged.

Confirm that the motor shaft has been inserted into the coupling until its tip comes into contact with the partition plate of the coupling and then tighten the coupling to the specified torque using the hexagon socket head cap screw.

Note that when your motor shaft is tapered, the coupling cannot be attached using the same procedure as described above.

Gearhead Installation

Mount the gearhead onto the specified position. At this point, align the counterbore for the gearhead with the tap of the stay.Tighten all the hexagon socket head cap screws (with a conical spring lock washer) uniformly, by using the specified tightening torque.

Note: Do not apply external load to the hollow section of the RD-C series. It could warp the oil seal.
