Definitions
- the invention relates to a Ronde with two Ronde plates, which are mutually adjustable about an axis of rotation and of which a first Ronde plate has an inner ring gear and a second Ronde plate radial guides for at least two locking slide, wherein the locking slide having a tooth portion which is connected to the inner ring gear cooperates and the Ronde further comprises a release device which moves the locking slide from the normally present locking position, in which they are in engagement with the internal ring gear in a release position.
- Round blanks of the type mentioned are widely known from the prior art, they are also referred to as Rastronden. Between the Ronde plates identical locking slide are provided, which are normally in the locked position. Such blanks are previously known, for example, from US Pat. No. 6,149,235 and DE 10 2005 050 222 A1.
- Such blanks have torsion springs, which pre-load a control axis of the blank into the zero position, which corresponds to the blocking position of the locking slide. If the release axis is twisted against the action of this torsion spring, it takes with it a control disk, which in turn pulls the individual locking slide from the locked position. In this state, the Ronde can then be adjusted.
- the locking slide are already biased in the locked position. It turns out, however, that this preload is not always uniform for all gate valves and is also not independent of the other gate valves for all gate valves. About the control disc a more or less mechanical coupling of all gate valves is achieved. Although this is favorable, in particular during the release process, but not always advantageous in a blocking operation. This is where the invention begins. It has set itself the task of making the preload of the individual locking slide in the engaged position independent of mechanical specifications and to achieve that the gate valves are biased elastically into the locking position without mechanical contact with the control disk.
- a formed as a stamped part spring is provided, which extends over at least 180 ° and which has a number of locking slide corresponding number of investment areas that each a contact area on a gate valve is applied, and that the spring has a bearing spring for each investment area.
- the spring is formed as a stamped part and can therefore be made extremely easy. It takes up so little space that existing constructions that work without the spring need not be changed, but rather the spring can be added.
- the spring is essentially in the form of an annular spring, in any case at least as a partial ring spring. With two pushers it extends over at least 180 °, with more than two pushers over a correspondingly larger angular range, namely at least (n-1) 360 / n degrees. In this case, n is the number of the locking slide or the contact areas.
- the spring is supported in the radial direction only on the pushers. In that regard, at least three locking slide advantageous because then a stable position is achieved. In other words, the spring is positioned by the gate valves. It requires no further positioning, at best in the axial direction, the spring must be defined.
- each contact area forms a radially outwardly acting abutment spring.
- the spring In the relaxed state, the spring is slightly larger than in the installed state and in the blocking position located pushers. When the gate valves are pulled into the release position, the spring is compressed, thereby deforming each individual bearing spring.
- the contact areas are preferably angled. As a result, a surface contact with the associated locking slide is effected.
- shoes or the like can be placed on the free ends of the flat spring, which take over the function of the bends. It is also possible to form a groove in the locking slides, which lies on a radial plane and engage in the free ends of the flat spring without bending. However, mounting on bends or shoes is easy.
- the spring can be inexpensively manufactured as a stamped part of a spring steel sheet.
- the steel sheet used may be relatively thin, material thicknesses below 0.5 mm, preferably below 0.3 mm are sought.
- the spring has a central recess. This makes it possible that the spring has no contact with a control axis or other components.
- each of the abutment areas is connected to an abutment spring which extends substantially in the circumferential direction, in any case having a larger component in the circumferential direction than in the radial direction.
- This simple spring arms are formed, the investment areas have a sufficiently large Fe ⁇ derweg, for example, 1 to 4 mm.
- the abutment springs run like arms of a spiral galaxy.
- FIG. 1 is a perspective view of a blank with three pushers
- FIG. 2 a perspective view with viewing direction corresponding to II-II in FIG
- FIG. 1 A first figure.
- FIG. 3 A perspective view of a second embodiment of a blank, also with three pushers and now in an indication: Hll-5/08 their viewing direction as FIG. 1,
- FIG. 4 is a perspective view of a spring, as used in the two preceding embodiments,
- FIG. 5 shows a side view of the spring according to FIG. 4 and FIG
- Fig. 6 a plan view of a second embodiment of the spring.
- the Ronde has a first Ronde plate 20 and a second Ronde plate 22. These are about an axis of rotation 24 against each other adjustable, so rotatable.
- the first blank plate 20 has an internal gear ring 26.
- the second blank plate 22 has three radial guides 28 for each one of a total of three slide valves 30. These gate valves 30 are identical to each other. They each have a tooth portion which cooperates with the internal toothed ring 26.
- the Ronde has a release device. Its task is to pull the locking slide 30, which are normally in the locked position, in a release position.
- the release device has an adjustment axis 32, which at the same time supports a pinion 34 connected in a rotationally fixed manner to the first blank plate 30.
- the release device furthermore has a torsion spring 36. It loads the adjusting shaft 32 in a direction of rotation corresponding to the zero position of the adjusting shaft 32, in this position the locking slide 30 are engaged.
- the release device further includes a control disk 38. It has suitable arms to attack on pins which are provided on the locking slides 30, and to be able to free the locking slide 30 from the meshing during rotation.
- the control disk 38 is associated with a control spring 40 which is formed similar to the torsion spring 36 and also supported on the second blank plate 22.
- a spring 42 is provided between the control disk 38 and the pushers 30, . It is designed as a ring spring, at least partial ring spring. It has a number of contact areas 44 corresponding to the number n of control disks 38. In all embodiments shown, it has three contact areas, but it may also have two, four, etc., contact areas. At least three contact areas 44 are preferred.
- Each contact area 44 is associated with a locking slide 30 and is elastically applied to the associated locking slide 30.
- Each abutment area 44 forms a free end. He is also a free end of a contact spring 46, which is part of the spring 42.
- the contact spring 46 it is ensured that each contact area 44 can move elastically in the radial direction independently.
- the goal is that the abutment springs 46 are formed so that they press the abutment portions 44 radially outward. A movement in the circumferential direction may be possible to a small extent, but it does not have to be present and is advantageously not present.
- the spring has a flat base part 48.
- the base part 48 also forms the abutment springs 46.
- the contact areas 44 are formed in the preferred embodiment as bends. They protrude from the plane of the base part 48 at right angles. The extent to which they protrude corresponds approximately to the material thickness of the locking slide 30, in any case adapted to the material thickness.
- the contact areas 44 are in the circumferential direction about 2 to 6, in particular 2.5 to 4 mm long.
- the contact areas 44 are substantially rectangular.
- the spring 42 has a central recess 50.
- the inner diameter is greater than the diameter of the adjusting shaft 32, preferably at least twice as large. As a result, the spring 32 is not in contact with the adjusting axis 32.
- the recess 50 is also larger than the outer diameter of the control spring 40.
- the spring 42 In the assembled state, the spring 42 abuts axially on both the control disk 38 and the locking slides 30. In contrast to the prior art, in which the spring 42 is not provided, the spring 42 contributes only very slightly to the overall height of the blank in the axial direction.
- the spring 42 in the embodiment of Figures 4 and 5 extends over about 250 °. It is folded symmetrically to a plane passing through its central abutment areas 44 and is perpendicular to the base portion 48.
- the spring is annular. It is similar to a spiral galaxy formed, it has three spiral arms, these spiral arms form
