Definitions
- the invention relates to a sleeve coupling according to the preamble of claim 1.
- sleeve couplings are known in which a plurality of button-like driving body, evenly distributed around the circumference of the spindle, are arranged in blind holes.
- the driving elements designated as coupling buttons are hollow and hat-shaped.
- the coupling buttons are made of resilient material so that they can be inserted into the blind holes. They engage in their installed state with their edges in undercuts, which are introduced into the blind holes.
- a helical compression spring is inserted into the blind holes.
- the helical compression spring pushes the clutch button constantly outward.
- the holder of the sleeve is done by spring force. The force that must be overcome when attaching and removing the sleeve is relatively large.
- EP 0 517 341 A1 shows an element for centering and fixing a sleeve on a spindle of a
- the sleeve is not fixed by coupling buttons, but instead by the polygonal elastic element.
- the element is elastically deformed when plugged onto the spindle sleeve and presses with its rounded corners against the inner wall of the sleeve.
- the force for fixing and entrainment of the sleeve is applied exclusively by spring force. As is known, this relatively high force can hinder the bobbin change. It is the Doffvorgang the spinning machine to overcome a strong frictional force.
- the generic DE 43 23 068 Al shows a sleeve coupling whose trained as a thin-walled cap body are also loaded by a helical compression spring.
- additional mass body are used.
- the spring force of the helical compression spring and thus the resistance when pushing the sleeve at a standstill of the spindle can be kept low and amount to only 30 to 70 percent of the value that is usually required, for example, for a known from CH 464 751 loaded solely by a helical compression spring entrainment , When the spindle is stopped during the doffing process, only the spring force acts as Contact pressure of the cap on the sleeve.
- An inventively designed sleeve coupling is equipped with coupling buttons that can be easily, quickly and accurately mounted in the holes.
- a time-consuming plastic deformation of the spindle by means of pressing tools during assembly of the coupling buttons is not necessary. It is also not necessary to form the spindle partially consuming as a hollow spindle and provide to cover the cavity of the hollow spindle caps.
- the coupling buttons according to the invention are robust and wear-resistant. The interior of the holes is against Pollution effectively protected - Should dirt settle on the outer edge of the bore, it can be removed again from the coupling knob.
- the coupling buttons are designed so that only caused by their mass centrifugal forces sufficient for a secure mounting and entrainment of the sleeve during rotation of the spindle.
- the spring elements secure the coupling buttons against falling out of the hole. A limited clearance of the clutch knob relative to the bore or the spindle in the radial direction remains. The insertion is easy to perform.
- the diameter of the cylindrical coupling button is slightly smaller than the diameter of the bore. At its inwardly directed at installation end, it has a circumferential groove into which a separate spring element is inserted.
- the spring element is preferably made of spring wire and is advantageously designed as an oval ring. Preferably, the ring is open on one side. Such a ring is inexpensive and easy to manufacture. The assembly can be done easily and quickly. Width and depth of the groove are larger than the diameter of the spring wire, so that the spring element can be completely absorbed by the groove.
- the compression of the spring element during insertion of the KupplungsknÜs in the bore is facilitated by the designed as an oval and open ring shape of the spring element and the circular cross-section of the spring wire. If the coupling knob is inserted so deep into the hole that the groove has reached the undercut of the hole, no effect radial force more on the spring element. The spring element therefore spreads apart again and acts as a secure holder against falling out of the coupling knob from the hole.
- a preassembled module is required for the pre-assembly of Kupplungsknöpf and spring element as well as for insertion into the bore of the spindle only a small amount of time.
- the clutch button can be produced easily and with little effort, but also the cooperating with him spring element.
- Each consisting of Kupplungsknöpf and spring element pre-assembled assembly can be used after assembly in the respective designated bore of the spindle. The required effort for the final assembly is reduced.
- Clutch knob and spring element can be assembled easily and with little effort.
- a spindle formed according to claim 7 enables a stable three-point support and centering in a single plane with the minimum number of only three coupling buttons.
- Each consisting of Kupplungskn ⁇ pf and spring element pre-assembled module is also suitable for retrofitting Installation in spindles, which already have suitable undercuts, and can thus replace existing driving body.
- the sleeves can be easily put on and peel off.
- the coupling buttons exert no spring force on the inner surface of the sleeves.
- the sleeve coupling according to the invention can be operated functionally reliable and low pollution and is wear resistant.
- the design is inexpensive to manufacture and quick and easy to assemble.
- 1 is a pre-assembled assembly consisting of a coupling knob and a spring element, in side view,
- FIG. 1 the assembly of FIG. 1 in plan view
- FIG. 3 the assembly of FIG. 1 in a perspective view
- Fig. 5 is a partial section through a spindle with a
- FIG. 6 shows a cross section through a spindle with three coupling knobs in the operating position.
- the preassembled module shown in Fig. 1 consists of a Kupplungsknöpf 1 and a spring element.
- the coupling knob 1 has a groove 2 into which the spring element formed as an open ring 3 is plugged. At the end opposite the groove 2, the coupling knob 1 has a convexly curved coupling surface 4.
- the oval shape of the ring 3 can be seen in the plan view of the coupling button 1 of FIG. 2, the oval shape of the ring 3 can be seen.
- the ring 3 is open between the free ends 5, wherein the free ends 5 are clearly spaced from each other.
- the free ends 5 of the ring 3 are in the groove 2, as the illustration of Figure 2 and the perspective view of FIG. 3 reveals.
- the portion of the ring 3 opposite the open portion is located completely in the groove 2.
- the shape of the ring 3, in conjunction with the groove 2 results in a secure hold on the coupling knob 1.
- Fig. 4 shows the coupling knob 1 during insertion into the bore 6 of the spindle 7.
- the preassembled assembly consisting of the coupling knob 1 and the open ring 3 with the end to which the groove 2 is introduced, ahead in the bore 6 introduced.
- the insertion is facilitated by a chamfer 12 on the edge of the bore 6.
- the coupling knob 1 is pressed into the bore 6 until it has reached, for example, the bottom 9 of the bore 6.
- the ring 3 is directed in this phase of insertion by the impressions with a radially to the wall of the bore 6 Stressed force and completely sunk in the groove 2.
- Fig. 6 shows a sleeve coupling, which is formed in the illustrated embodiment as a three-point centrifugal clutch.
- protruding coupling knobs 1 are pushed into the holes 6 of the spindle 7, with no spring forces are overcome.
- the clutch buttons 1 are in the operating position, which is assumed when the spindle 7 rotates operating speed.
- the coupling knobs 1 are pressed during rotation with their coupling surfaces 4 under the action of centrifugal force to the outside against the inner wall of the sleeve 11. As a result, the sleeve 11 is effectively centered during operation to the spindle 7 and securely fixed in position.
- the spindle 7 is stopped. It no longer acts centrifugal force on the coupling knobs 1 and thus no radial forces on the inner surface of the sleeve. The sleeve 11 can now easily be removed from the spindle 7 again.
