2 Series CRQX/ Model Selection The selection procedure of the rotary for low-speed is the same as for an ordinary rotary. If the rotation time exceeds s per 9, however, the necessary torque and the kinetic energy are calculated with rotation time of s per 9. Selection Procedure Remarks Selection Example Operating conditions Operating conditions are as follows: Provisionally selected model Operating pressure: MPa Mounting position Load type Static load: N m Resistance load: N m Inertial load: N m Load dimension: m Load mass: kg Rotation time: s Rotation angle: rad See P. 3 for load type. The unit of the rotation angle is Radians. = πrad 9 = π/rad Load Load r =,. kg. kg Calculation of moment of inertia Calculate the moment of inertia of the load. P. 33 Calculation of necessary torque Calculate necessary torque corresponding to the load type, and ensure it is within effective torque range. Static load (Ts) Necessary torque T = Ts Resistance load (Tf) Necessary torque T = Tf x (3 to ) Inertial load (Ta) Necessary torque T = Ta x P. 3 If the moment of inertia of the load is made up of multiple components, calculate the moment of inertia of each component and add them together. When calculating the inertial load, if the rotation time exceeds s per 9, inertial load is calculated with rotation time of s per 9. Even for resistance load, when the load is rotated, necessary torque calculated from inertial load shall be added. Necessary torque T = Tf x (3 to ) + Ta x Provisionally selected model: BA Operating pressure:.3 MPa Mounting position: Vertical, Type of load: Inertial load Rotation time: s Rotation angle: πrad ( ) Load moment of inertia: I. +. I =. x +. x. =.33 Load moment of inertia: I. I =. x +. x. =.3 Total moment of inertia: I I = I + I =.39 [kg m ] Inertial load: Ta Ta = I ω θ ω = [rad/s ] t Necessary torque: T T = Ta x x π =.39 x x =. [N m] (t is calculated with s per 9.). N m < Effective torque OK 3 Checking rotation time Confirm that it is within the adjustable range of rotation time. P. 3 Converted to the time per 9 for comparison. (For comparison, s/ is converted to 3s/9.). t t = 3s/9 OK Calculation of kinetic energy Confirm that the load s kinetic energy is within the allowable value. Can be confirmed by the graph of the moment of inertia and the rotation time. P. 3 If the rotation time exceeds s per 9, kinetic energy is calculated with rotation time of s per 9. If the allowable value is exceeded, an external cushioning mechanism such as an absorber needs to be installed. E = I ω θ ω = t Kinetic energy x π x.39 x =. [J] (t is calculated with s per 9.). [J] < Allowable energy OK Checking allowable load Check if the load applied to the product is within the allowable range. If the allowable value is exceeded, an external bearing needs to be installed. M =. x 9. x. +. x 9. x. =.39 [N m] P [N m] < Allowable moment load OK 3 Calculation of air consumption and necessary air quantity Calculate air consumption and necessary air quantity as required.

4 Model Selection Load Type Calculation method of necessary torque depends on the load type. Refer to the table below. Static load: Ts Only pressing force is necessary. (e.g. for clamping) Load type Resistance load: Tf Weight or friction force is applied to rotating direction. Inertial load: Ta Rotate the load with inertia. l ω l F Gravity is applied. mg Center of rotation and center of gravity of the load are concentric. l mg ω μ Friction force is applied. Rotation shaft is vertical (up and down). Ts = F l Ts: Static load (N m) F : Clamping force (N) l : Distance from the rotation center to the clamping position (m) Gravity is applied in rotating direction. Tf = m g l Friction force is applied in rotating direction. Tf = μ m g l Tf : Resistance load (N m) m : Load mass (kg) g : Gravitational acceleration 9. (m/s ) l : Distance from the rotation center to the point of application of the weight or friction force (m) μ : Friction coefficient θ Ta = Ι ω = Ι t Ta: Inertial load (N m) Ι : Moment of inertia (kg m ) ω : Angular acceleration (rad/s ) θ : Rotation angle (rad) t : Rotation time (s) For low speed rotary, if the rotation time exceeds s per 9, inertial load is calculated with rotation time of s per 9. Necessary torque: T = Ts Necessary torque: T = Tf x (3 to ) Note) Necessary torque: T = Ta x Note) Resistance load: Gravity or friction force is applied to rotating direction. Ex. ) Rotation shaft is horizontal (lateral), and the rotation center and the center of gravity of the load are not concentric. Ex. ) Load moves by sliding on the floor Note) To adjust the speed, margin is necessary for Tf and Ta. The total of resistance load and inertial load is the necessary torque. T = Tf x (3 to ) + Ta x Not resistance load: Neither weight or friction force is applied in rotating direction. Ex. ) Rotation shaft is vertical (up and down). Ex. ) Rotation shaft is horizontal (lateral), and rotation center and the center of gravity of the load are not concentric. Necessary torque is inertial load only.

However, applications which apply a load directly to the shaft should be avoided whenever possible.

7 Rotary Actuator Technical Data Air Consumption Air consumption is the volume of air which is expended by the rotary actuator s reciprocal operation inside the actuator and in the piping between the actuator and the switching valve, etc. This is necessary for selection of a compressor and for calculation of its running cost. The air consumption (QCR) required for one reciprocation of the rotary actuator alone is shown in the table below, and can be used to simplify the calculation. Formulas P +. QCR = V x x -3. P QCP = x a x L x x -. QC = QCR + QCP QCR = Air consumption of rotary actuator [l (ANR)] QCP = Air consumption of tubing or piping [l (ANR)] V = Internal volume of rotary actuator [cm 3 ] P = Operating pressure [MPa] L = Length of piping [mm] a = Internal cross section of piping [mm ] QC = Air consumption required for one reciprocation of rotary actuator [l (ANR)] When selecting a compressor, it is necessary to choose one which has sufficient reserve for the total air consumption of pneumatic actuators downstream. This is affected by factors such as leakage in piping, consumption by drain valves and pilot valves, etc., and reduction of air volume due to drops in temperature. Formulas Qc = Qc x n x Number of actuators x Reserve factor Qc = Compressor discharge flow rate n = Actuator reciprocations per minute Reserve factor:. or greater Internal Cross Section of Tubing and Steel Piping Nominal size T T TU T /B T 7 TU T 9 /B TS 3/B T 3 /B 3/B B O.D.

24 Series CRQX/ Specific Product Precautions Be sure to read before handling. Refer to front matters 3 and 39 for Safety Instructions and pages to 3 for Rotary Actuator and Auto Switch Precautions. Selection Caution. Changes in speed occur in applications in which there are changes to the load during operation, such as the load being lifted (lowered) against gravity.. The purpose of this product is stable rotation at lowspeed. It does not provide any function to cushion the impact at the operation start or end. 3. Speed may vary at the rotation end depending on operating conditions.
