Definitions
- the present invention relates to a rotary drive u. a. for two-part, foldable floor and Gallery stairs, in which a linear drive by means of two parallel, level Can convert four-bar gearbox into a rotary actuator.
- the new rotary actuator should be designed so that it has a relatively large Has idle of the motor drive when changing the load direction, u. a. by one Overuse while moving up the stairs or during use avoid and also to allow an adjustment of the ceiling height.
- the new part-turn actuator should be as universal as possible and inexpensive to manufacture and easy to install.
- a max. Swivel angle of at least 180 ° and / or a large, relatively uniform Has torque can be used as universally as possible and is inexpensive to manufacture and can be easily installed.
- a swivel drive is formed, which consists of two parallel, flat four-bar gearboxes, one laterally or centrally with the U-shaped frame (1, 31) of the four-bar linkage frame (7, 20, 32) or a box (41) and one arranged between the two four-bar transmissions, on the one hand with the frame or the box (41) and on the other hand with the drive members (2) of the four-bar transmission articulated linear drive (10), for. B. a linear motor or a hydraulic Cylinder.
- the two four-bar transmissions each consist of a drive member (2), one or two Coupling members (3), an output member (4) and a common U-shaped frame (1, 31) or a box (41).
- the two output members (4) are either on their own Component or rigidly connected to each other and serve as the drive member of the swivel drive u. a. for a motor drive of the stairs. Because of the rigid connection between the two Output members (4) is an even load for the laterally acting load reached the two gears so that the linear drive (10) can work properly.
- the torque or the swiveling movement can be the same as for normal Rotary drive also directly through the pivot shaft (53) of the output members (50) on the the two output members (50) are connected in a rotationally fixed manner to the working machine become. In this case there is a rigid connection between the two output members (50) not necessarily.
- the two drive elements (2) move identically and can be connected to each other become.
- the four-bar gearboxes are designed so that the swivel angle of the Output members (4, 50) is larger than that of the drive members (2). This can also be a cheaper movement transmission at both end positions with the same swivel angle of the Output member (4, 50) can be achieved.
- the four-bar mechanism can be used in the movable joints Elongated holes (5) are used so that the linear drive (10) continues to run when Change of loading direction or after reaching the end position of the Output elements (4, 50) can take place and thereby overload the drive is avoided and u. a. the stairs can also be easily adjusted to the ceiling height. It is It is advisable to use the elongated holes identically on both four-bar gears.
- This swivel drive can be designed without difficulty so that the Main load on the pressure load of the linear drive (10) is set so that it i. a. can output a higher driving force with the same dimensions. Both a great one Swivel angle of over 180 ° as well as a large, relatively even torque can be removed from the output members (4, 50).
- This swivel drive can be open, partially closed or closed.
- the frame can be arranged laterally or centrally as required.
- a rotary actuator with a laterally arranged frame (7, 20) for the Motor drive represented a staircase, which without much narrowing of the passage at the Side of the hatches can be attached.
- the U-shaped frame (1, 31) can be constructed so that it is a partially or completely closed form (41) and at the same time the function of the frame for the linear drive.
- this rotary actuator can be used in addition to a cost-effective production practically wear and maintenance-free.
- the quarter turn actuator consists of two identical, parallel, planes Four-link mechanism, one on the side of the U-shaped frame 1 of the four-link mechanism welded square tube 7 with a rectangular tube 20 welded to it as a frame and one arranged between the two four-bar transmissions, on the one hand with the frame and on the other hand articulated with the drive members 2 of the four-bar linkage Linear motor 10.
- the two four-bar four-bar gears each consist of a drive member 2, two coupling links 3, an output link 4 and a common U-shaped frame 1.
- the U-shaped frame 1 are two axes 17 and 18 as fixed axes of rotation of the two Four-bar gearbox arranged.
- the axis 17 protrudes from the frame 1 and serves at the same time as the axis of rotation of the stairs.
- the coupling members 3 are on the one hand by means of rivets 13 with the Drive members 2 and on the other hand articulated by means of rivets 14 with the output members 4 connected.
- Elongated holes 5 are instead of round holes on the output members 4 for the rivets 14 provided to avoid overstraining and to easily adjust the To allow ceiling height.
- the rivets 14 are in the use state of the stairs normally not at the end of the elongated holes 5 (see Fig. 2 and 3).
- the two output links 4 are welded together by means of an intermediate piece 16 and act as one solid component.
- the frame 7, 20 is fastened to the hatch box 6 by means of tabs 8 welded to it and on the rectangular tube 20, an eye plate 9 for hanging the linear motor 10th welded.
- the linear motor 10 hangs on the one hand by means of a pin 11 on the eye plate 9 and on the other hand by means of a pin 12 with two spacers 24 on the two Drive links 2.
- a fitting 21 is attached, the one hand directly on the cantilever Axis 17 depends and on the other hand by means of the screw 15 and a spacer 23 to the Output members 4 is attached so that the stairs 22 together with the output members 4 pivot or can be driven by this rotary actuator.
- the spacer 23 can be formed as a part of the fitting 21 or of the output members to improve the load capacity of the rotary actuator.
- the linear motor 10 switched or the linear motor 10 extends.
- the two Drive members 2 driven by the linear motor 10 and pivot accordingly and pull the coupling links 3 by means of the rivets 13.
- the rivets 14 at the other end of the Coupling links 3 first move along the elongated holes 5 and then pull the Output members 4 on when the rivets 14 are at the end of the elongated holes 5. Then swivel the output members 4 with the attached stair part 22 accordingly.
- the stairs 22 is in the stowed state brought and the linear motor 10 is by the built-in limit switch at the other end off.
- an embodiment of an open swivel drive is alternatively with a central frame 32 shown.
- the corresponding U-shaped frame 31 and the Connection tab 33 are firmly connected to the frame 32. If necessary, the Drive the quarter turn actuator simultaneously from both sides. Since the construction of the here shown swivel drive with the swivel drive shown in Fig. 1 to 3 otherwise is identical to the further numbering of components and the Functional description waived.
- an embodiment of a closed swivel drive is alternative shown with a box 41.
- the box 41 also takes on the function of the U-shaped here Frame and frame for the linear motor and can with a cover 42nd be locked.
- a corresponding one is used to remove the swiveling movement Slot 43 made in the box, which in turn is covered by a circular disc 44 can be.
- This circular disc 44 is like the fitting 21 in FIGS. 1 to 3 with the Output members (4) connected and hanging on the cantilever of the axes (17).
- to Transfer of the pivoting movement are four holes 45 with thread on the Round disc 44 is provided so that the driven machine is attached to it.
- This swivel drive can also drive simultaneously from both sides if required if the corresponding design changes are made to box 41.
- the swivel drive shown here with the one in FIGS. 1 to 3
- the swivel drive shown is also identical, is based on the further numbering of components and the functional description.
- 9 and 10 is an embodiment of a closed swivel drive alternatively shown with a drive shaft 53 made of a square bar.
- the two Output members 50 are provided with a corresponding square hole or with the shaft 53 rotatably connected, so that the pivoting movement to the driven Machine can continue to transmit.
- the two bearing elements 52 have the corresponding square hole in the middle and also serve as Spacers.
- This rotary actuator can drive from one side or from both sides. Since the Construction of the rotary actuator shown here with that shown in Fig. 1 to 3 Swivel drive besides the obvious and clear difference in the frame too otherwise identical, is based on the further numbering of components and the Functional description waived.
- the fastening tabs or the like of the leg drive are not shown in FIGS. 4 to 10 shown and can be easily attached to the frame or box as needed become.
