Definitions
- the invention shows a buildable connection of two parts with large area moments of inertia, as they require, inter alia, drives as a joint with angular compensation, and a propeller shaft built therewith.
- Couplings and joints for connecting two parts are manifold.
- Universal joints transmit torques with angled shaft sides with forks over a spider.
- the pins are bent against the central crossing region, through which the force is directed to the driving pin-fork pairing.
- the result is a high load in the neck of the cones at the intersection.
- the installation of the spider in the forks requires space for threading into the bearing eye and plugged sockets or split bearing eyes. Only for simple requirements can thin and flexible tubes with bearing eyes elastic over put the pins.
- the cardan error is compensated as a cardan shaft in W or Z arrangement to the driving and ablating sides, but the oscillating accelerated spacer remains critical and calls, inter alia, a specific low mass.
- EP 10709498.9 shows a design for machine assemblies whose multi-part components intermesh by twisting about their connection line.
- the invention has for its object to show a powerful, easy to build connection with angle compensation and the application as a built propeller shaft. This object is achieved with the features specified in claim 1.
- the invention has the further object to show a powerful connection two parts. This object is achieved with the features specified in claim 10. description
- An angle-compensating joint per se connects a pivoting movement out of the connection axis with the rotationally and tension-fixed connection of input and output side about the connection axis.
- the two crossed pivot axes of the universal joint are inventively realized separately for each page.
- It rotationally symmetric and positive complementary interventions which lie on the inner or outer surface of pans or ball half shells and keep the pan on the complementary saddle pivotally, the forces on large radii and over large areas.
- Each page represents a self-contained pivot joint.
- the interventions undercut each side in cylindrical circumferential and axial direction and thus hold both torques and tensile forces, and they undercut optional and advantageous in the ball-radial direction of the joint center. The latter prevents a stretched lifting of the part to be joined from its socket directly in the connection, while this traditionally prevents a stiffer and thus thicker body of the bearing eyes.
- the rigid connection of both sides can be conventional or advantageous for building and coupling by means of a bolt with just such interventions as those for the pivoting movement. Collisions of both parts during the pivoting movement are prevented by clearances. In the limit case, a built, non-rotatable connection without clearance and thus without swivel range as a coupling is possible.
- FIG. 1 shows a compound according to the invention.
- Figure 2 shows the middle pans to Figure 1 enlarged.
- FIG. 3 shows an application of the compound according to FIG. 1.
- FIG. 4 shows the assembling of the connection according to FIG. 1.
- FIG. 5 shows an adjusting device for a coupling connection.
- Figure 6 shows a further advantageous embodiment of the middle pan.
- FIG. 7 shows a closed bellows for one side of the connection
- FIG. 8 shows another version of the connection.
- FIG. 1 shows an exploded to the latch 3 representation (la) of a compound 20 according to the invention, and their side view (lb), and the views of the assembled compound from above (lc) and from the side (ld).
- the individual parts are continuously associated with engagement axes (11 to 1, 12.1 and 12.2 to 2, 13 to 3, 14.1 and 14.2 to 4, 15 to 5) as the axis of symmetry for each engagement area - inside and outside with subitems 1 and 2.
- the outer parts 1 5 are the parts to be joined. They have free spaces 18 (FIG. 1b, c) and can thus be pivoted on their pans 2 4 and thus tilt their zenith axes 10 and 16 against each other.
- each half shell or each shell sector is assigned a zenith axis which passes from the center through the surface center of the shell sector.
- the axes of engagement of a position are perpendicular to the zenith axis.
- FIG. 3 shows such a tilting with respect to the main axis 60 of the connection using the example of a propeller shaft.
- FIG. 2 shows, by way of example, the inner and outer engagement regions 22.1 and 22.2 or 24.1 and 24.2 and their axes 12.1 and 12.2 or 14.1 and 14.2 for the ladle 2 and 4, respectively.
- the engagement region is clearly indicated for better clarity omitted and referred to only the engagement axes.
- the engagement areas of the two sides of the shell may have skewed engagement axes.
- the engagement axes 14.1 and 14.2 of the pan 4 intersect perpendicularly in the center of its envelope ball.
- the engagement areas are rotationally symmetrical about their axes of engagement 11 to 15 carried out and thus allow the rotation of the parts about them in pairs as a half-shell system with inner and outer shell and aligned axes of engagement; they form a hemispherical stack in the screwed state.
- the grooves near the pole can form undercuts, so that they absorb tensile forces in the direction of their zenith axes and hold the interlocking pairs of parts together.
- the grooves can therefore be designed as a rotationally symmetrical serration.
- the figures show the pans 2, 4 advantageously connected via a bolt 3 with similar interventions as between the parts and their pans (1 with 2 and 4 with 5) releasably connected for coupling.
- the pans 2 and 4 can also be connected to the parts to be connected 1, 5 conventionally releasably or permanently after screwing. Only through the connection of the pans 2, 4 forces are transmitted between the sides, whereby in relation to the conventional fork-pin (cross) pairing specifically larger area moments of inertia arise for the acting surfaces.
- the damping over the connection, advantageously by the bolt 3, be decoupled from the guide decoupled by the bolt is designed as a damping elastomer, the engagement areas of the pan-parts pairing with matching sliding mating in hardened metal or in plastics ,
- the grooves may in a further advantageous embodiment for better stiffening of the half shells with each other radially undercut profiles to also from Joint center point seen in all solid angle radial forces absorb. This can prevent a spherical symmetric radial gapping or local or total lift off at different temperature expansions of the shells.
- Figure 2 shows in isometric view and in the view into the pans in grooves with additional undercut, dovetail-like profiles 21 in the enlargement of the pans 2 4 together with the different engagement axes 12.1, 12.2 and 14.1, 14.2 to their inner and outer engagement areas 22.1, 22.2 or 24.1, 24.2.
- the profiles 21 for the grooves are distributed regularly on a pitch circle.
- the parts 1 and 5 have around their engagement axis 11 and 15 circumferential grooves. Their internal grooves engage in complementary grooves on the outside of the associated pan 2 and 4, as shown in Figure 4g and 4h.
- the parts 1 5 may have a matching body, which integrate the engagement areas shown as a connection. Both parts 1, 5 may have different spaces or interventions.
- Figure 3a, b shows a propeller shaft in known W and Z arrangements with two integrated connections 20 as a universal joint.
- the parts 1 and 5 are integrated in the shaft parts as la, b and 5a, b respectively. Since parts 1 and 5 are identical here, the order of designation is arbitrary. Clearly, the advantageous slim structure with very low interference contour.
- FIG. 4 The procedure for assembling the connection 20 according to the invention according to FIG. 1 is shown in FIG. 4.
- the engagement areas are not shown in the sections of FIGS. 4a to 4f, but are shown in isometric view on the selected parts in FIGS. 4g and 4h.
- pan 4 is positioned opposite part 5 and screwed into the complex-tart engaging regions.
- the bolt 3 has also been screwed in advance in the pan 4 and now rotates with.
- FIG. 4d the likewise assembled stack of trays made of part 1 and cup 2 are positioned congruently with the inner engagement regions in relation to the stack of lc completely screwed in here.
- the pan 2 has on its inner side the same procedures as pan 4 and allowed so that the latch 3 also absorb, as shown in Figure 2.
- Figure le shows the latch 3 after the stacking of the stack pairs rotated back by 90 °, as he engages in both sides and connects them.
- the outer pans 2 4 and parts 1 5 do not come directly with the other side in engagement. A contact can even be prevented by appropriate distances, which can facilitate tilting in the radial positioning.
- the pans can be dome. Also, the bolt 3 can cling as a section of the hemisphere, for example, executed as a dome.
- the bolt 3 can be supplemented with a second latch 3 ', which then engages as the first in pan 4 in the pan 2, the full ball. Then, after the positioning according to FIG. 4d, both bars rotate over each other into the opposing pan and, in the working position, they cling with a double surface (FIGS. 1f and 1h). In addition, imbalances can be easily avoided.
- Figures lg and lh show closed connections with hidden positions part 1 and pan 2.
- the closing latch 3 is shown with a multi-part adjustment and holding device 40 from Bowden cable 40.1 with retainer 40.2 and actuator 40.3.
- the bolt can take the just introduced until then holder at point 41.
- the adjustment can also be done with one cable per direction of rotation similar to the Bowden cable or rubbing a wheel or combing at point 41 done.
- a fixation can be realized by elastic springs or pawls between latch and pan conventional.
- the access to the bar 3 through the outer pans 4 and 5 part to pass in the zenith axis of the pan, so that only a small weakening of the forces transmitting surfaces is given.
- the actuator 40.3 can be led outside in a noncritical range.
- the access through part 5 has to take into account the pivoting with respect to the pan by appropriate clearances. Thus, an opening is possible even in the tilted position. Since the pan 4 does not pivot relative to the latch 3 during operation, the weakening of the outer part 5 can remain small in certain applications, in that only in the non-tilted orientation of the zenith axis 16 of the part 5 access to the adjustment device 40 can take place. So otherwise needed more space in part 5 are avoided.
- parts 1 and 5 can advantageously be made identical for the reduction of individual parts.
- the outer interference of the pans 2 4 are fixed, the inner can be the same for the bolt 3.
- the engagement axes 12.1, 12.2 of the pan 2 are not designed to be zero degrees and the engagements 14.1, 14.2 of the pan 4 rotated by 90 °, as previously shown, but each rotated by 45 ° in opposite directions ( Figure 6a). Since the pans in the connection are rotated by 180 ° to each other, the outer axis 12.2 folds with identical design of the pans 2 and 4 now to the axis 14.2, as simplified in Figure 6b as a rear view of the axes without pan 4 and in parentheses the axis 12.2 not shown with folded pan 2. They (12.2 and 14.2) then intersect as before by 90 °, while the inner axes are aligned 12.1 and 14.1 and the bolt 3 can connect the pans 2 4. The entire connection is thus advantageously only two or - with optional latch - of three parts.
- All parts or positions represent in particular in their intervention areas sectoral rotation body to the highest 180 ° and can be finished in the direction of rotation without undercuts, edit and handle.
- the parts can be cast and removed from the mold by rotating or loosening the mold depending on the area of engagement.
- the process essentially corresponds to the disassembly, wherein, for example, the pan 4 of Figure 1 and 2 between bars 3 and Part 1 is poured, then the bolt is rotated around its engagement axis 13 - it corresponds to the generated engagement axis 14.1 -, then the pan about the axis of engagement of the part 5, which corresponds to the Ab from their engagement axis 14.2.
- some or all parts of the connection or the propeller shaft are advantageous in optionally fiber-reinforced plastic, in injection-moldable ceramics or other composites including castable renewable raw materials to produce cheap.
- connection can be tube-like designed as a hollow connection and, after assembly, e.g. in a hollow drive shaft inside installations for e.g. Compressed air, oil, data, energy, inspection equipment or cooling protected central rotating or dormant.
- the joint Since the pivoting movement advantageously does not engage in the other side, the joint has three separate regions, consisting of i) part 1 with pan 2 outside, ii) pan 2 inside (with bar 3 and optional 3 'and) with pan 4 inside and iii ) Pan 4 on the outside with part 5.
- protective bellows and seals can be laid on one side so that a separation of the connection does not injure or open them.
- the bellows or seals only allow the pivoting movement between the pan and part of a side. In this way, lubrication or pressure areas in the area of the joints can be kept closed and closed even when open. Lubricants can not escape.
- the middle area (point ii above) encapsulates the bars in use against dirt and moisture. A simple ring seal between the pans is reached.
- FIG. 8 shows an embodiment of the connection where the bars 3, 3 'each have a cylindrical stump 3.1, 3. ⁇ outward, which is rotatably guided by free spaces in the other parts and the i) for locking as well as ii) as a separate Connection to a third direction or iii) can serve as a third or fourth connected part.
- Fig. 8a) hold all parts together
- Fig. 8b) also the front side is also fully occupied.
