Description

  • The invention relates to a swivel motor according to the preamble of claim 1 and to a corresponding manufacturing method according to the preamble of claim 2.
  • Such swivel motors are used in particular in the aviation and automotive industry to fulfill a wide variety of tasks. A preferred field of application is the vehicle industry, in which the swivel motor is used in conjunction with stabilizers for roll stabilization of a motor vehicle.
  • Such a swivel motor is for example in the DE 197 25 412 C2 described. This swing motor consists of a stator which is connected to a first stabilizer part, and a rotor which has connection to a second stabilizer part. The stator has two radially aligned stator vanes and the rotor has two likewise radial rotor vanes. In this case, the two stator blades and the two rotor blades in conjunction with two end caps form two opposite hydraulic working chambers so that the stator blades and the rotor blades can be pivoted to one another against the hydraulic load in one of the two working chambers.
  • For internal sealing of the two working chambers with each other, each stator blade is equipped with a frame sealing element which is inserted in the stator and sealingly abuts the outer periphery of the rotor, while each rotor blade carries a same frame sealing element, which bears sealingly on the inner circumference of the stator.
  • The stator and the two stator blades are made in one piece, resulting in a complicated contour of the inner surfaces. These inner surfaces have to fulfill different tasks, wherein the lateral surfaces of the stator vanes are designed for a pure stop function, while the inner peripheral surfaces of the stator act as sliding and sealing surfaces.
  • To produce such a stator under series conditions, a cold-extruded tube is used as the starting part, which is first turned off to the corresponding lengths of a stator housing. Thereafter, the inner contour of each blank is finished by the manufacturing process spaces in three moves. The best achievable surface quality of Rz = 10 is sufficient for the stop function. For the sliding and sealing function of the inner peripheral surfaces of the stator, this quality is unsatisfactory, because this usually a surface finish of Rz = 1.0 to 2.0 is required.
  • In this respect, a swivel motor equipped with such a stator does not achieve its performance parameters because, because of the roughness of the sealing surfaces, the inner tightness between the pressure-carrying working chamber and the unpressurized working chamber can not be guaranteed. Because of the rough surface of the stator, the frame sealing elements are also subject to higher wear, so that the pivoting motor also has only a limited life. Furthermore, the production of such a stator is in particular by the Clearance process manufacturing technically very expensive and expensive.
  • To improve the sealing function has already been tried to improve the surface quality by a subsequent lapping. There have also been efforts to develop such frame sealing elements that adapt to the rough surface. Ultimately, all these attempts have failed because of the high costs or the limited installation conditions.
  • Another prior art forms the US 4,492,150 showing a hydraulic tilting actuator. The actuator allows a reversal of rotation, wherein the inner part against the outer part rotatably provided with a stop (rotor / stator principle).
  • The US 5,979,163 also shows a hydraulic der- / or rotary actuator. The rotor pivots in a stator housing and its rotation is limited by the fixed stators. The device shown here is as it were as Bewegungsbegrenzer and as a rotary actuator in suspension.
  • The DE 29 05 193 describes a fluid-actuated rotary drive, which is provided with the stator housing, here end plates, firmly screwed stator vanes. These also limit the rotational movement of a hydraulically driven rotor.
  • In the US 2,793,623 there is disclosed a hydraulic motor having adjustable rotation stops. The rotation stops are attached to a stator wing; which is connected via a groove with the inside of the stator housing.
  • The JP 10281108 shows a hydraulic rotary actuator, the stator vanes are defined from the inside in the stator housing.
  • The invention is therefore based on the object to improve the surface quality of the inner peripheral surfaces of the stator of a generic swing motor and at the same time to reduce the manufacturing cost.
  • This object is achieved on the device side by the features of claim 1 and the method side by the features of claim 2.
  • The new swing motor and the new manufacturing method eliminate the aforementioned disadvantages of the prior art.
  • The invention will be explained in more detail with reference to the following drawings.

  • After Fig. 1 the swivel motor consists of a stator 1 and a rotor 2, wherein the stator 1 on the one hand with a first stabilizer part 3 and the rotor 2 on the other hand is connected to a second stabilizer part 4.
  • The stator 1 consists of a cylindrical stator housing 5, a first stator cover 6 arranged on the one hand of the stator housing 5 and a second stator cover 7 located on the other side of the stator housing 5. Both stator covers 6, 7 are firmly bolted to the stator housing 5 and are each provided with a continuous bearing bore. In the opposite bearing bores of the two stator cover 6, 7, a rotor shaft 8 of the rotor 2 is rotatably fitted and sealed by respective sealing elements 9, 10 with respect to the two stator covers 6, 7 hydraulically.
  • As the Fig. 2 . 5 and 11 show, the rotor 2 has two opposite rotor blades 11. These rotor blades 11 are integrally formed with the rotor shaft 8 and matched with their radially oriented heads on the inner wall of the stator 5. For this purpose, each rotor blade 11 is provided with a, over its entire axial length extending and groove-shaped recess, in a frame sealing element 12 is inserted. This frame sealing element 12 consists in a known manner of a plastic with an elastomeric core and a circumferential sealing frame, preferably made of a PTFE. This frame sealing element 12 lies in a sealing manner with one of its long legs on the inner circumferential surface of the stator housing 5 and with its two short legs on both stator covers 6, 7.
  • In the stator 5, two opposite stator blades 13 are used, which are also each equipped with a groove extending over its entire axial length and groove-shaped. In this recess, a frame sealing element 12 is fitted in each case, which rests in a sealing manner with one of its long legs on the outer peripheral surface of the rotor shaft 8 and with its two short legs on both stator cover 6, 7. Thus, two opposing and pressure equal pressure chambers 14 and two opposite and equal pressure discharge chambers 15 form, which are volume variable by the limited relative pivoting between the stator blades 13 and the rotor blades 11. In this case, the pressure equality of the respective opposite pressure chambers 14 and drainage chambers 15 is achieved by introduced in the rotor shaft 8 connecting channels 16.
  • The stator housing 5 and the two stator blades 13 are now designed in two parts in a special way.
  • Thus, the stator housing 5 in one embodiment according to the Fig. 3 , which is not part of the invention, formed as a tube and has two opposite and longitudinal receiving slots 17 with a limited length for the two stator vanes 13. Accordingly, each stator vane 13 after the Fig. 4 equipped with a longitudinal receiving spring 18. Everybody owns it Receiving slot 17 has a circumferential conical surface, which increases the receiving slot 17 in the radial direction from the inner diameter to the outer diameter of the stator housing 5. In contrast, each receiving spring 18 of the stator blade 13 has a circumferential conical surface, which decreases in the radial direction from the inside to the outside. The inner dimensions of the receiving slot 17 and the outer dimensions of the receiving spring 18 are coordinated so that the smaller dimensions of the receiving slot 17 and the larger dimensions of the receiving spring 18 are compatible with each other. The cone angle is chosen so that in the fitted state results in a suitable for a weld seam 19.
  • In a further embodiment according to the Fig. 5 to 8 not part of the invention, the tubular stator housing 5 has two opposite and extending over the length of the stator housing 5 keyways 20. The keyways 20 have on top of that in cross section a dovetail shape. Matching is the stator blade 13 after the Fig. 8 provided with external dimensions, which allows axial insertion of the stator blade 13 in the corresponding keyway 20 and prevents radial falling out of the keyway 20. The wedge angle of the splines 20 and the outer shape of the stator blade 13 are the same size and chosen so that adjusts a clamping and self-locking frictional engagement. Likewise, as it can Fig. 7 shows a clamping and self-locking frictional engagement between the stator housing 5 and each stator blade 13 by two parallel and rectified keyways 20 'in the stator housing 5 and corresponding wedge springs in the stator wing 13 can be achieved.
  • In a further embodiment according to the FIGS. 9 and 10 not part of the invention, the two stator blades 13 are bolted to the tubular stator housing 5 and additionally secured in position. The position is secured by a fitting groove 21 in Stator housing 5 and by a feather key 22 on the stator wing 13 in place of the tongue and groove fuse and a pin-hole fuse can be made.
  • To ensure the tightness between the working chambers on both sides of the stator vanes 13, each stator vane 13 is equipped with at least one longitudinal groove for a sealing element 23.
  • In an embodiment according to the invention according to the Fig. 11 For each stator vane 13, the tubular stator housing 5 has a position securing groove 24 extending over the entire axial length, while the stator vane 13 is designed as a feather key in its outer area. The position securing groove 24 of the stator housing 5 and the feather key area of the stator vane 13 form a groove-spring connection, which exclusively assumes the task of preventing rotation. Alternatively, the anti-rotation, like the Fig. 12 shows, also consist of two parallel Lagersicherungsnuten 24 'in the stator housing 5 and accordingly two feather keys in the stator blade 13.
  • In the area of its side surfaces protruding from the stator housing 5, the stator vane 13 is wedge-shaped over its entire axial length. Between the two stator vents 13 used against rotation in the stator housing 5, one spacer shell 25 is used on the one hand and on the other hand, the side surfaces of which also run wedge-shaped. The wedge angle of the side surfaces of the stator vanes 13 and the side surfaces of the spacer shell 25 are the same size and chosen so that a clamping and self-locking frictional engagement is formed by the axial insertion of the spacers 25.
  • Such a stator 1 is manufactured as follows. As a starting product for the production of the stator 5 in the first three Embodiments according to the Fig. 1 to 10 , which are not part of the invention, a commercially drawn drawn and innengehohntes tube is used. Due to its pre-machining, the inner circumferential surface of this tube has a surface quality of at most Rz = 2 and is thus very well suited as a sealing surface. A subsequent fine machining is therefore not required. The tube is turned off to the corresponding lengths of the stator housing 5. Thereafter, the receiving slot 17 for the first embodiment, the keyways 20, 20 'for the second embodiment or the fitting groove 21 and the mounting holes for the third embodiment are machined into the stator housing 5 in a conventional machining manner.
  • For this purpose, the stator blades 13 are manufactured in a conventional manner with the appropriate dimensions and shapes and inserted into the stator housing 5.
  • Thereafter, the stator housing 5 and the stator blade 13 in the embodiment, after Fig. 3 , which is not part of the invention, welded together by a low-distortion welding process, pressed together in the second embodiment or positionally secured and screwed together in the third embodiment. Finally, the two end faces of the completed stator 1 are planned in a conventional manner and introduced the provided cover holes and sealing grooves.
  • As a starting product for the production of the stator housing 5 in the fourth embodiments of the Fig. 11 and 12 a commercially available pipe is used, which has no special requirements to meet the surface finish of the inner peripheral surface. Thereafter, the Lagersicherungsnuten 24 after the Fig. 11 or the position securing grooves 24 'after the Fig. 12 introduced into the stator housing 5.
  • For this purpose, the stator blades 13 in the conventional manner with the s.den Lagersicherungsnuten 24, 24 'adapted dimensions and shapes produced and inserted into the stator housing 5. At the same time, the spacers 25 are manufactured in a conventional manner and in such dimensions and in such a form that they respectively fit between the two stator vanes 13 using an axially acting contact pressure and thereby bear against the inner peripheral surface of the stator housing 5 over the whole area. In this case, the inner surface of each spacer shell 25 is processed with a conventional Feinstbearbeitungsverfahren to a surface finish of Rz = 1 to 2.
  • After completion of the items, the stator blades 13 are inserted into the position securing grooves 24, 24 'and then pressed against each other using the distance shells 25 to the self-locking.
  • Finally, the two end faces of the completed stator 1 are planned in a conventional manner and introduced the provided cover holes and sealing grooves.
