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 outwards.
  • 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.
  • the mass of the clutch knob is low. Therefore, the force with which the clutch button presses against the inner surface of the sleeve, applied largely only by the spring force during rotation of the spindle.
  • the spring force must be at least so large that the sleeve is taken safely. This relatively high force can hinder the bobbin change, if the empty, mecanicsteckende sleeve only by its own weight to reach operating position and to the coupling buttons against the spring force perpendicular to their direction of movement must press into the blind holes in it.
  • At doffing on a spinning machine is a strong frictional force to overcome both pulling off and plugging.
  • the EP 0 517 341 A1 shows an element for centering and fixing a sleeve on a spindle of a ring spinning machine.
  • 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.
  • An alternative solution also from the CH 464 751 is known, constitute massive coupling knobs, which are driven by centrifugal force radially outward during rotation of the spindle and are pressed against the inner wall of the sleeve.
  • the solid coupling knobs are each inserted into an axial cavity of the spindle and inserted with their cylindrical part from the inside to the outside in holes. In the holes they are kept movable.
  • the coupling buttons on retaining shoulders whose diameter is greater than the diameter of the cylindrical part of the coupling knob.
  • the partial design of the spindle as a hollow spindle is expensive. There is an additional protection against contamination of the spindle interior is needed, for example, a specially designed cap with a cylindrical extension. Inserting the clutch button requires skill and is time consuming. In addition to the assembly effort and the production cost, especially for the spindle is relatively large.
  • the DE 44 30 709 A1 describes a sleeve coupling for spindles, are provided in the radial through holes.
  • the centrifugal bodies have at their emerging from the radial through holes end faces in each case a convexly curved coupling surface with adjoining conical contact surface, which is called shoulder.
  • the shoulder is to prevent the centrifugal body during operation of the spindle, so in its rotation about the axis of rotation of the spindle bearing part is thrown off, if once no sleeve should be attached to the spindle bearing part.
  • each shoulder is assigned a corresponding mating surface on the outer circumference of the spindle lifting part.
  • the generic DE 43 23 068 A1 shows a sleeve coupling, designed as a thin-walled cap driving body are also loaded by a helical compression spring.
  • additional mass body are used in the elastic deformable caps.
  • the spring force of the helical compression spring and thus the resistance when pushing the sleeve at standstill of the spindle can be kept smaller and only 30 to 70 percent of the value, for example, for one of the CH 464 751 known exclusively by a helical compression spring loaded driving body is usually required.
  • the spring force acts as Contact pressure of the cap on the sleeve. As the speed increases, the contact pressure increases due to the centrifugal force acting on the additional mass.
  • 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. If dirt settles on the outer edge of the bore, it can be removed from the coupling button again.
  • 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 play of the coupling knob relative to the bore or to 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 coupling knob 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 the coupling button and spring element as well as for insertion into the bore of the spindle only a small amount of time. Not only the clutch button can be produced easily and with little effort, but also the cooperating with him spring element.
  • Each consisting of coupling button and spring element preassembled module can be used after assembly in the respective designated hole 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 solid steel clutch button which is advantageously hardened, is wear resistant and has a relatively large mass. Due to its mass, it acts on the rotation of the spindle, the inner wall of the sleeve particularly well with a force required for fixing the sleeve.
  • 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.
  • coupling button and spring element preassembled 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.
  • preassembled module consists of a coupling button 1 and a spring element.
  • the coupling knob 1 has a groove 2 into which the spring element designed 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.
  • 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, is inserted in the first hole 6.
  • the insertion is facilitated by a chamfer 12 on the edge of the bore 6.
  • the coupling button 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.
