Technical Information Actuators 1.3 Choice of shuttle cylinder: RexMover Besides its driving function, the RexMover cylinder guides the parts to be moved. Apart from the maximum permissible force, permissible torques have to be considered in designing these cylinders. Value and direction of these torques can be very different. Always try to ensure that the distance between the cylinder guide and the centre of gravity of the load is as short as possible. The permissible loads are determined by the type of guidance. Both maximum speed and maximum mass to be cushioned are determined by the driving medium and the kinetic energy permitted. Cases of Application (figures, see 1.3.1 to 1.3.4) The design described here is meant for the following cases of application: A A mass is driven and guided by the cylinder. B C D A mass is driven by the cylinder, the guidance is carried out externally. By means of the cylinder a force is transmitted to a standing object. Static forces and torques on the slide. Loads on the Cylinder 1) The mass leads to torques on the slide due to the acceleration and cushioning and the weight during the movement. 2) The guidance leads to torques on the slide due to the friction. The mass generates a torque during acceleration and cushioning. 3) The force leads to torques on the slide. 4) Counter force which does not act half-way between the shuttles gives a moment on these. 5) Mechanical load of cylinder and guidance when the piston is stopped. Procedure in Designing the Cylinder 1. Determine the case of application (A-D) (see Fig. 1.3.1 to 1.3.4). 2. For this application determine lever arms as well as masses (kg) and moving speeds (m/s) (see Fig. 1.3.5 to 1.3.10). 3. Based on the diagrams and charts, select appropriate cylinder. Assumptions - A pressure of 6 bar is always taken as a basis. - The diagrams are applicable for moving speeds of up to 0,7 m/s. If these are exceeded, the actual mass has to be multiplied by a correction factor of 2v 2. Then calculations have to be continued with the corrected mass. The diagrams have been made for both horizontal and vertical applications. - To be sure that you will have good pneumatic control on the piston movement and reduce the risk of failure when e.g. starting up, let m/a (m = mass in kg and A = area in cm 2 ) not to be higher than 4 for horizontal cases and 2 for vertical cases. Estimation of cycle time Please note: Often it is not the cylinder speed that is known, but only the cycle time. By means of diagram 1.3.1 conversion can be made. As to the diagrams for the dimensioning of the cushioning, calculations have to be based on the actual mass. If the cushioning capacity of a cylinder is not sufficient, either a larger cylinder or external shock absorbers have to be used which are to be mounted in the centre of the mass to be cushioned. The values of STAR guidance include cases with large shocks. Also consider the play and stiffness of the cylinder when selecting cylinder. (See table 1.3.2 and diagram 1.3.19) Also consider maximum effect from the cylinder, see diagram 1.3.17 and 1.3.18. For individual applications different diagrams and charts have to be observed. Contact the nearest Rexroth Mecman office. Diagram 1.3.1 Vertically up Horizontal Vertically down As a starting point the relationship m/a is used where m is the load on the cylinder (kg) and A is the cylinder piston area (cm 2 ). A pneumatic cylinder is not normally loaded higher than m/a 4. The cycle time can be estimated from the diagram above. The pressure drop P p over the piston with a vertically ascending movement can also be read off. Example: A 63 mm diameter cylinder with a 200 mm stroke is to move a mass of 45 kg vertically upwards. Estimate the time for a single stroke if the final velocity of the cylinder is to be 0.7 m/s. Answer: According to table 1.1.1, the piston area A = 31 cm 2. m 45 = = 1.5 A 31 The time for a single stroke where km is read from the diagram is as follows: km s 1.6 200 t = = = 0.45 seconds 1000 v ss 1000 0.7 It can also be seen from the diagram that a pressure drop of ~1.5 bar over the cylinder piston is needed in order to overcome the mass load. km t = s/v 1000 ss t = cycle time (s) s = the cylinder stroke (mm) v ss = piston steady state velocity (m/s) Limitation: accuracy is reduced for short cylinders. 50
Technical Information Actuators Back to Index Layout for Applications A and B 1. Determine lever arms and masses. 2. Determine if you need a correction factor based on the velocity. 3. By means of the torque diagrams, (diagrams 1.3.2 to 1.3.10) select cylinder alternative and cylinder diameter. If 2 torque diagrams require the same cylinder diameter, the next larger cylinder is to be selected. (Example: Diagram M results in 25, diagrams M s and M v in 32, a cylinder of 40 has to be applied). 4. Depending on the installation position and p1.3.ressure medium, check cushioning according to diagrams 1.3.11 to 12. 5. Compare 3 and 4, the largest diameter must be used. 6. For good pneumatic control of the piston movement, especially when the stroke is short, let m/a be less than 4 for horizontal and 2 for vertical cases. C Fig. 1.3.3 Layout for Application C The resulting permissible forces have to be taken from diagram 1.3.17 and 1.3.18. Layout for Application D The cylinder diameter required has to be determined based on table 1.3.3. D Control of rodless cylinders The control of the rodless cylinder has to be realised such that the pneumatic cushioning works reliably even after a pressure breakdown or when starting the system again. This is possible only when the secondary chamber of the cylinder is charged. A * The measure EH must be included in XZ, see the dimension drawings D Fig. 1.3.4 Fig. 1.3.1 B Fig. 1.3.2 51
