We generate a torsional stiffness curve by slowly applying torque to the output in the following sequence: (1) Clockwise torque to TR, () Return to Zero, () CounterClockwise torque to TR, () Return to Zero and () again Clockwise torque to TR. A loop of (1) > () > () > () > () will be drawn as in Fig. 01. The torsional stiffness in the region fro "0.1 x TR" to "TR" is calculated using the average value of this slope. The torsional stiffness in the region fro "zero torque" to "0.1 x TR" is lower. This is caused by the sall aount of backlash plus engageent of the ating parts and loading of the planet gears under the initial torque applied.

The hysteresis loss between "Clockwise load torque TR" and "Counter Clockwise load torque TR" is defined as the backlash of the HP series.

11 HighPerforance earhead for Servootors Product Sizing & Selection To fully utilize the excellent perforance of the HP HaronicPlanetary gearheads, check your operating conditions and, using the flowchart, select the appropriate size gear for your application. In general, a servo syste rarely operates at a continuous load and speed. The input speed, load torque change and a coparatively large torque is applied during start and stop. Unexpected ipact torques ay also be applied. Check your operating conditions against the following load torque pattern and select a suitable size based on the flowchart shown on the right. Also check the life and static safety coefficient of the cross roller bearing and input side ain bearing (input shaft type only). Flowchart for selecting a size Please use the flowchart shown below for selecting a size. Operating conditions ust not exceed the perforance ratings. Calculate the average load torque applied on the output side fro the load torque pattern: Tav (N). Calculate the average output speed based on the load torque pattern: no av (rp) Checking the load torque pattern Review the load torque pattern. Check the specifications shown in the figure below.

13 HPP/ The thin wall flexible gear technology used for HaronicDrive gearing is applied to the internal gear of our planetary gear speed reducers. It allows the internal gear to defor elastically thus aintaining low backlash for the life of the gearhead, without the need for adjustent. Planetary gears have siultaneous eshing between the sun gear and planet gears and between the planet gears and the internal gear. Soe anufacturers try to reduce the backlash by controlling the diensional precision of the parts, however this causes interference of eshing parts due to diensional errors, resulting in uneven input torque and noise. Haronic Planetary gears use a thin wall elastic internal gear which allows a preload of the gear and copensates for interference between eshing parts. The Haronic Planetary gear series incorporates this internal gear which aintains low backlash for the life of the speed reducer. Low backlash: Less than arcin (Less than 1 arcin also available) Low gear ratios, :1 to 0:1 High efficiency High load capacity by integrating structure with cross roller bearing Hightorque capacity earheads 1

Checking procedure (1) Checking axiu load Calculate: Maxiu load oent load (Mi ax) Maxiu load axial load (Fai ax) Maxiu load radial load (Fri ax) () Checking the life Calculate: Average oent load (Mi av) Average axial load (Fai av) Average input speed (Ni av) HP HPF Maxiu load oent load (Mi ax) Perissible oent load (Mc) Maxiu load axial load (Fai ax) Perissible axial load (Fac) Maxiu load radial load (Fri ax) Perissible radial load (Frc) Calculate the life and check it. Specification of input shaft bearing The specification of the input side ain bearing of the input shaft unit is shown below.
