Definitions
- the invention relates to a compensating coupling for the transmission of torques to compensate for alignment inaccuracies of machine elements to be connected.
- Elastic couplings are known, such as pin couplings, where one coupling half carries studs, on the free ends of which rubber bushes are fitted as an elastic intermediate member, which engage in the correspondingly enlarged bores of the second coupling half.
- pin couplings where one coupling half carries studs, on the free ends of which rubber bushes are fitted as an elastic intermediate member, which engage in the correspondingly enlarged bores of the second coupling half.
- Travel length is the number of lug packets, distributed among the handling, limited, because otherwise the necessary number of individual parts and the diameter increases too much.
- the invention is therefore based on the object, by using a larger number of springs, distributed over the circumference of the coupling, and by improving the spring elements, to provide a compensating coupling which, despite the compensation of axial and radial alignment errors, while also taking into account a long service life, is also appropriate Transmits torque.
- This object on which the invention is based is achieved by configuration according to the characterizing part of claim 1. Further advantageous embodiments can be found in the subclaims.
- the compensation coupling according to the invention has the advantage over the existing state of the art that, despite compensation for any shaft misalignment in the axial, lateral and angular direction through the introduction and arrangement of the various slots in the spring, not only high torques can be transmitted, but at the same time long-term durability of the spring designed as connecting and transmission elements.
- the spring elements can be inexpensively manufactured from high-quality steel in large quantities and can be incorporated into the coupling design in the intended coupling series with a few sizes and with a high degree of variance in the respective torque ranges.
- the assembly, disassembly and repair of the clutch, using the spring according to the invention as a connecting element, can be accomplished simply and quickly.
- the spring mounted therein is protected so that even in the event of a break, the immediate area is protected against flying parts. Due to the intended accuracy of fit, even a burst spring transmits the torque and thus contributes to the emergency running properties of the clutch. Due to the radial rigidity of the individual springs and the possibility of using a larger number of springs, the load on the individual spring is extremely low, so that breakage can hardly occur.
- Fig. 1 is a plan view of one side of the differential clutch
- FIG. 2 is a side view of FIG. 1 in section
- FIG. 3 shows a side view of the spring.
- FIG. 4 shows a side view of the spring according to FIG. 3 in section.
- FIG. 5 shows a top view of the spring according to FIGS. 3 and 4
- 1 and 2 consists of two coupling halves 1, 2 designed as shaft flanges.
- the driver parts 3, 4 are provided with different bores 5, 6, for example.
- recesses 7, 8, analogous to the spring 9 to be introduced.
- the recesses 7, 8 have a threaded bore 10 in the center.
- the face of the flange of the coupling half 2 is also congruent with recesses 8 and additionally with recesses 11. With a slightly larger diameter than the recesses 11, threaded holes 12 are also made in the rear of the flange of the coupling half 2.
- the spring 9 to be mounted in and between the coupling halves 1, 2 according to FIGS. 3 to 5, as a compensating and connecting element, is cylindrical with different diameters.
- the middle part of the spring 9 with its outer diameter 13 fits precisely against the recesses 8 of the two coupling halves 1, 2 during assembly, while the collar 14 which has been worked on engages in the flange of the coupling half 1 and the collar 15, which is larger in diameter, with its stop - Flat 16 for the recess 11 in the flange of the coupling half 2 is used.
- the spring 9 is designed such that it consists of a cylindrical tubular body, by creating at least two opposite spring elements 18 transversely to its longitudinal axis 17, in which four equally opposite slots 19 are made.
- the slots in one half of the tubular body are designed such that the outer slots 19 in the upper half and the two internal slots 19 in the lower half are carried out overlapping.
- the incorporation then takes place in exactly the opposite way, so that
- the spring 9 is assembled, for example, by the collar 14 of the spring 9 being received through the recesses 7 in the flange of the coupling half 1 and with a cylinder or Allen screw 23 in the threaded bore 10 via the bore 24 of the collar 14 with its stop surface 25 for the screw head of the Allen screw 23 is screwed.
- the spring 9 is also inserted into the recesses 8 and pressed into the recesses 11 with the enlarged collar 15 and via the existing threaded bore 12, which is located on the rear side of the flange of the coupling half 2, by a nut 26 additionally secured with external thread and hexagon socket.
