The switch can be fixed in the desired position in the circumferential direction. Side ported Axial ported Connecting port location: Side ported or Axial ported The port location can be selected according to the application. ( to with unit(s) are side ported only.) Double vane type is standardised for 9 and. The outside dimensions of the double vane type are equivalent to those of the single vane type (except size ). Double vane construction can get twice the torque of the single vane type. Series Vane type Rotating angle 9 Basic type CRB2 Single With angle adjuster CRB2BWU Double Features 1

3 Working Principle/How to Mount Loads Series CRB2 Vane Type Series Single vane (S) Double vane (D) Shaft Vane Stopper Shaft Vane Stopper CRB2 Body Body 1. It consists of a shaft that is integrated with the vane that slides along the inner surface of the body, and a stopper. 2. The air that is supplied from port A pushes the vane, thus creating torque in the shaft. 3. The air in the exhaust chamber discharges via port B and rotates clockwise.. The vane stops as it comes in contact with the stopper. 5. Similarly, when air is supplied from port B, it rotates counterclockwise. 1. It consists of a shaft that is integrated with the 2 vanes that slide along the inner surface and 2 stoppers. 2. The air that is supplied from port A passes through the passage in the shaft in order to also supply air to the other chamber. Thus, the air pushes 2 vanes and creates torque in the shaft. 3. Its movement consists of the same rotation as that of the single vane. How to Mount Loads How to connect a load directly to a single flat shaft To secure the load, select a screw of an appropriate size from those listed in tables (1) and (2) by taking the shaft's single flat bearing stress strength into consideration. Single flat Table (1) Using Screw Directly (Fig. 1) Series Shaft bore size Screw M or larger CRB2 5 6 M5 or larger 8 M6 or larger Table (2) Using Holding Block (Fig. 2) Series Screw CRB2 Shaft bore size M3 or larger M or larger M5 or larger Plate thickness [t] 2 or wider 2.3 or wider 3.6 or wider or wider The plate thickness [t] in the table above indicates a reference value when a carbon steel is used. Besides, we do not manufacture a holding block. Fig. 1 Fig. 2 Screw for holding a load Hexagon socket head cap screw Holding block Front matter 1

Thin round plate Position of rotational axis: Perpendicular to the shaft through the centre of gravity Position of rotational axis: Through the centre of diameter a r 2. Thin rectangular plate Ι = m Position of rotational axis: Parallel to side b and through the centre of gravity b a a a 2 + b Ι = m 2. Round plate (Including column) b Ι = m a 2 a 2 3. Thin rectangular plate (Including rectangular parallelepiped) Position of rotational axis: Perpendicular to the plate through the centre of gravity Position of rotational axis: Through the centre axis 7. Cylinder (B) r a (A) r Ι = m Ι = m 3r 2 + a 2 8. When the rotational axis and load centre of gravity are not consistent L 9. Gear transmission r 2 Position of rotational axis: Through the centre of diameter and gravity. Ι = K + m L 2 Number of teeth = a K: Moment of inertia around the load centre of gravity. Round plate K = m r Solid sphere r Ι = m r 2 2 Position of rotational axis: Through the centre of diameter Number of teeth = b 1. Find the moment of inertia ΙB around the rotation of shaft (B). 2. ΙB is converted to the moment of inertia ΙA around the rotation of shaft (A). ΙA = ( a ) 2 ΙB b r Ι = m 2r 2 5 Front matter 3

6 Model Selection 1-2 Calculation Example of Moment of Inertia 1 If the shaft is located at a desired point of the load: Centre of gravity of load Example) 1. If the load is the thin rectangular plate: Obtain the centre of gravity of load as Ι1, a provisional shaft. Ι1 = m a 2 + b 2 2. Obtain the actual moment of inertia Ι2 around the shaft, with the premise that the weight of the load itself is concentrated in the load s centre of gravity point. Ι2 = m L 2 3. Obtain the actual moment of inertia Ι. Ι = Ι1 + Ι2 m: Weight of load L : Distance from the shaft to the centre of gravity of load Calculation Example a =.2 m, b =.1 m, L =.5 m, m = 1.5 kg.2 Ι1 = 1.5 x = 6.25 x -3 kg m 2 Ι2 = 1.5 x.5 2 = 3.75 x -3 kg m 2 Ι = ( ) x -3 =.1 kg m 2 2 If the load is divided into multiple loads: Load 1: Ι1 Load 2: Ι2 Example) 1. If the load is divided into the 2 cylinders: The centre of gravity of load 1 matches the shaft. The centre of gravity of load 2 differs from the shaft. Obtain the moment of inertia of load 1: Ι1 = m1 2. Obtain the moment of inertia of load Obtain the actual moment of inertia Ι. Ι = Ι1 + Ι2 r1 2 2 r2 Ι2 = m2 2 + m2 L 2 2 m1, m2: Weight of load 1 and 2 r1, r2: Radius of load 1 and 2 L: Distance from the shaft to the centre of gravity of load 2 Calculation Example m1 = 2.5 kg, m2 =.5 kg, r1 =.1 m, r2 =.2 m, L =.8 m Ι1 = 2.5 x = 1.25 x -2 kg m 2 Ι2 =.5 x x.8 2 =.33 x -2 2 kg m 2 Ι = ( ) x -2 = 1.58 x -2 kg m 2 Front matter

Set range of Block = 135 (195 ) End r End w End e End q Block <Fig. 1-1> Clockwise End w Hatched area represents a stopper lever. Set range of Block = 9 Single flat End q (5 ) <Fig. 2-1> Clockwise Stopper ring Block Stopper ring Block Block Counterclockwise <Fig. 1-2> Lock Block in Fig. 1-2, and move Block clockwise to allow the rotation of the shaft with single flat in Fig. 1-1 from point zero to End q. When Block is locked and Block is moved counterclockwise, the shaft with single flat in Fig. 1-1 rotates from point zero to End w. The maximum rotation range of the shaft with single flat is as follows: s, : up to 2 ; s,, : up to 2 (Fig. 1-2 shows when the rotating angle is.) Example 3 The stopper ring is mounted on 1 clockwise from the standard position shown in Fig. 1-2 of Example 1 as in Fig. -2 of Example. End w Counterclockwise <Fig. 2-2> The maximum rotation range of the shaft with single flat in Fig. 2-2 is 195, from End q to End w. The rotation range of the shaft with single flat in Fig. 2-1 decreases to the range between End w and e when moving Block in Fig. 2-2 clockwise, and similarly when moving Block counterclockwise, the rotation range decreases to the range between End q and r. However, since the internal stopper will come into contact with the vane at End q position of the shaft with single flat in Fig. 2-1, make sure that the stopper lever stops at Block when adjusting. Example The stopper ring is mounted on 1 clockwise from the standard position shown in Fig. 1-2 of Example 1 as in Fig. 3-2 of Example 3.

However, since the internal stopper will come into contact with the vane at End q position of the shaft with single flat make sure that the stopper lever stops at Block when adjusting. End q side can be adjusted within by moving Block counterclockwise. Counterclockwise <Fig. -2> The maximum rotation range of the shaft with single flat is 27, from End q to End w, when using the actuator for 27 and End q side in Fig. -1 is stopped using the internal stopper and End w side is adjusted using Block. The rotation range can be adjusted within 9 in End w side. Note that Block cannot be moved and set 9 or more counterclockwise from its position in Fig. -2 since the internal stopper will come into contact with the vane. Note 1) Mounting of the stopper ring shown in Examples 2, 3, are not applicable for size. Note 2) marks in the illustrations above indicate the mounting position of the stopper ring. Note 3) Select the appropriate rotation of the rotary actuator after careful consideration of the content of Angle Adjustment Setting. Note ) For size, each block comes with 2 holding screws. 35
