Definitions

  • the invention relates to an external double-shoe brake for a spinning spindle, which is mounted in a spindle bank having a cover and has an essentially U-shaped brake body, the brake levers of which are connected in the central region can be set against the spindle by means of a spreading device.
  • a two-shoe brake for spinning and twisting spindles is already known as prior art (DE-OS 29 22 606).
  • This brake is designed like pliers and has two legs, a brake lever being clipped into the recesses of this leg via pins.
  • the brake lever spreads the legs apart, since an inclined footprint is arranged on each of these legs. This spreading apart of the legs causes a compression of further legs, which carry the brake shoes.
  • the disadvantage here is that when braking by swiveling up the brake lever, the brake body is tilted about a holding pin, as a result of which a unilateral force is exerted on the spindle.
  • spindle brakes which comprise the spindles in the manner of pliers (GB-PS 930 034). These spindle brakes have two side brake levers with brake shoes, which are mounted in a brake housing. A swivel lever equipped with a cam disk is provided for actuating these spindle brakes.
  • the disadvantage here is the complicated and therefore expensive construction. Another disadvantage is that these spindle brakes cannot be operated with the knee due to their pivoting lever.
  • the invention has for its object to provide an external double shoe brake of the type mentioned, which on the one hand is smooth and stable, can be manufactured cheaply and on the other hand clearly prevents unilateral application of force to the spindle when braking.
  • This object is achieved in that the brake body is held in a fixed position in the cover of the spindle bank and the spreading device which can be acted upon perpendicularly to the axis of the spindle is guided in the brake body.
  • This advantageously prevents a one-sided application of force to the spindle during braking with a simple construction of the outer double-shoe brake and thus increases the overall service life of the entire unit. Furthermore, there is a favorable power transmission of the individual elements, so that ease of use is ensured at low costs.
  • a spindle 2 is arranged in a spindle bank 1, which is driven by a tangential belt 9.
  • a spindle brake 3 which can be operated in the direction of arrow I.
  • this is an outer double-shoe brake with an essentially U-shaped brake body 4, the legs of which form brake levers 14, 14 'and are provided with brake shoes 13 on the front.
  • This brake body 4 has two arms 12 which are connected to one another in the central region 20, as well as two mutually opposite bearing points 8 and an expansion gap 11.
  • the outer double shoe brake also consists of an actuating element 5, which is held in a cover 7 of the spindle brake 1 and has an elastic cap 6.
  • This elastic cap 6 is assigned a spreading device 10 which projects into the spreading gap 11.
  • the expansion gap 11 is designed as a V-shaped recess.
  • the elastic cap 6 of the actuating element 5 can preferably be made of soft plastic, for example of PVC soft, while the spreading device 10 is made of hard plastic (e.g. thermoset).
  • the actuating element 5 in one piece from plastic, but it must be ensured that the cap 6 is of elastic design and the spreading device 10 has sufficient rigidity.
  • the spreading device 10 penetrates into the spreading gap 11, as a result of which the arms 12 of the brake body 4 are pressed apart. Since the actuating element 5 each has an abutment 8 'which interacts with a bearing 8 of the brake body 4, in cooperation with the central region 20, which serves as a hinge, the brake levers 14, 14' pivot about the abutments, 8 'the two brake shoes 13 are moved against each other and thus cause the braking process for the spindle 2 or the corresponding whorl.
  • the force transmission of the spindle brake according to the invention which is dependent on the wedge angle of the expansion gap 11 and on the length of the arms 12 and the brake lever 14, is approximately 6: 1 in the wedge angle of approximately 10 ° shown.
  • Such a translation results in a smooth running of the spindle brake according to the invention with a cost-saving structure.
  • a brake body 4 and an actuating element 5 in turn form the spindle brake 3.
  • a fixed stop 16 is used as an abutment for the brake levers 14, 14 ′, which is opposite the central region 20 of the brake body 4 and arranged on the actuating element 5 can be.
  • This abutment 16 designed as an abutment ensures that when the spreading device 10 penetrates into the expanding gap 11, the brake shoes 13 in turn move against one another and thus trigger the braking process for the relevant whorl of the spindle 2.
  • Fig. 4 shows this embodiment in side view, partially in section.
  • the two-part outer double shoe brake 3 also has a brake body 4 which has two brake levers 14, 14 'and brake shoes 13.
  • the brake shoes 13 are fastened to the brake levers 14, 14 'via a clip connection 21.
  • an adhesive connection not shown, instead of this connection.
  • the two brake levers 14, 14 ' are connected to one another via a web 24 in the base region 20 according to FIG. 5.
  • a support piece 22 is also arranged on the web 24, to which a fastening ring 23 is integrally formed at the end.
  • an actuating element 5 is again provided, which is made of soft plastic, and an expansion part 10 cast therein.
  • the expansion part 10 has a central one Recess 26, which surrounds the guiding and centering device 25.
  • This guiding and centering device 25 has wedge-shaped outer surfaces 27 and 28 which can be pushed between the arms 12 of the brake body 4 when the outer double-shoe brake is actuated and thereby apply the brake shoes 13 to the spindle 2 from the outside.
  • the actuating element 5 is placed over a collar 29 over the fastening ring 23 and fastened to it.
  • the support piece 22 is formed by two opposing webs 32 which merge into the fastening ring 23 on the front side. These two webs 32 each have a groove 31 for fastening the brake in the cover 7. There are two arms 12, which delimit the expansion gap 11, which in turn surrounds the guiding and centering device 25, are offset by 90 ° to the two webs 32 of the support piece 22.
  • This guiding and centering device is designed as a cylindrical pin.
  • the spreading device 10 cooperating with the guiding and centering device has a holding area 33 at the rear, which is cast into the elastic cap 6.
  • the wedge-shaped outer surfaces 27 and 28 penetrate into the expansion gap 11 and are guided by the guiding and centering device 25.
  • the brake shoes 13 rest on the outer circumference of the whorl of the spindle 2.
  • the brake body 4 and the brake shoes 13 can consist of material of different elasticity.
  • the brake body 4 and the brake shoes 13 are made in one piece from plastic.
  • neither the braking body 4 nor the actuating element 5 can apply one-sided forces to the spindle when the spindle brake is actuated exercise.
