Definitions

  • the invention relates a machine foot for supporting items such as devices and machines with a movable, preferably, metallic spindle with external thread, fastened to a base of a preferably polymer material.
  • the invention furthermore relates to a method for supporting items and machines.
  • the spindle can be moved freely in all directions within a certain angle, which is required when the machine foot is going to be used for e.g. levelling of a machine.
  • the force which will affect the machine foot, when it is used for its purpose, is transmitted from the spindle to the underlying base part via the ball part in the bottom of the spindle.
  • Another problem which originates from the force transmission from the ball part at the end of the spindle to the base part, occours as a result of that there is obviously an upper limit of how great a force there can be transmitted per unit area between the ball surface and the base part.
  • the size of this maximum allowable force per unit area will obviously depend of the selected material for the two force transmitting components.
  • the ball part is the most expensive single component in a machine foot, it is therefore expensive to transmit high forces via the ball shape, in that a big ball part must be used, which is relatively resource demanding to manufacture.
  • the object of the invention is achieved by a machine foot of the type stated in the introductory portion of claim 1 , which is characterized in that the spindle in the base ends with a ball segment, where the ball's diameter is smaller than the spindle's thread diameter.
  • the spindle between the thread and the ball segment is installed with a sleeve or a ring for transmitting the force from the machine base from the spindle to the base.
  • the spindle By providing the spindle with a ring or a sleeve for the force transmission from the spindle to the subjacent base it is achieved that the greater power there is being transmitted from spindle to base, the more the sleeve or ring squeezes around the base, whereby the open gap between the parts become smaller, the more power there is going to be transmitted.
  • the product becomes still more resistant to impurities and bacteria, the greater the pressure, which shall be transmitted.
  • the product will therefore be especially suited for application in environments, which sets high demands to hygiene.
  • the ball shape itself will here secure optimum force transmission with a minimal use of materials.
  • the invention also relates to a method for support of devices and machines.
  • This method is characterized in that there is used one or more of the in claim 1 to 6 described components for the support.
  • Fig. 1 shows a sectional view of an assembled machine foot.
  • Fig. 2 A shows a sectional view of the base part of a machine foot.
  • Fig. 2B shows the base part of a machine foot seen from above.
  • Fig. 3 shows an assembled machine foot where the spindle is turned in relation to the base part.
  • FIG. 1 a sectional view of a machine foot produced in accordance with the invention.
  • the machine foot consists of a spindle 1 with an external thread, which can be screwed into the machine or device, which needs support.
  • On the thread part of the spindle there is usually in the bottom such as grinded shapes for wrench connection, in order to fasten the spindle's thread part in the machine.
  • the spindle 1 is provided with a sleeve 3, which can also be a separate ring, which is mounted as shown in fig. 1.
  • the sleeve 3 encloses the base part 4 and is used for transmitting the force from the machine, which is supported from the spindle 1 to the base part 4.
  • the spindle 1 ends in the bottom of a ball part 2, which is fastened to the base 4 by the use of an undercutting in the base part, so that the ball part must be pressed into the undercutting in order to become fastened to this.
  • the ball part 2 in this way secures by mounting in the undercut base part 4 that the spindle 1 and the base 4 is held together during transport and assembly. Furthermore the ball shape 2 ensures that the spindle 1 can move freely in relation to the base part 4, within the limits, which lies in the gap cut/passage between the base part 4 and the spindle 3, which is often nedeed for adjustment of the machine support.
  • the sleeve 3 covers the free cutting/carving between the spindle 1 and the base 4 no matter which angle the spindle 1 assumes in relation to the base 4.
  • the base is in the bottom and up the sides provided with a dirt- and bacteria inhibitive material 8, which enhances the hygiene attributes of the product.
  • the machine foot is provided with the same dirt-- and bacteria inhibitive and blocking material in the gap/transition between the base 4 and a mounted cover 5.
  • the product is highly suited for application in environments with high demands to hygiene, including e.g. hospitals and slaughterhouses.
  • the ball part 2 can be made relatively small because it is not going to transmit the force from the machine support.
  • the material consumption and the final product weight can be reduced to a minimum.
  • the force transmission from the spindle 1 to the base 4 occours as mentioned via the sleeve or disc 3.
  • the disc and/or sleeve can obviously be manufactured from the same basis material as the spindle 1 itself, but can also be mounted on this as an isolated stand-alone disc. Especially if the force transmitting part is mounted on a stand-alone disc this is a particularly price favourable as well as in terms of weight light single component, which with advantage can have a larger diameter than the spindle's thread diameter, whereby very high powers cheaply, effectively and hygienically can be transmitted from the spindle 1 to the base 4.
  • the surface of the force transmitting disc or sleeve 3 is in the direction of the base part 4 shaped as part of a sphere/ball, which ensures an optimum force transmission per unit area and also ensures that the spindle easily can be turned in relation to the base, simultaneously with that the sealing between the components stays optimized.
  • the base part 4 is in the top, which touches the force transmitting disc 3, obviously shaped with a sphere segment form, which is complementary to the surface of the disc 3, which it is contact with.
  • the machine foot is provided with a cover 5, which eases cleaning.
  • a dirt- and bacteria inhibitive sealing material 8 and 6 which in a preferred embodiment can be a sealing polymer, including a sealing rubber.
  • the product will be sufficiently tight towards penetrating dirt or bacteria without an applied sealing polymer, in case the edge zone with contact with the cover and the base is shaped appropriately within suiting mechanical tolerances.
  • Fig. 2A shows the base part 4 in a sectional view, where the undercutting 11 is used for fastening the ends of the spindle, and where the opening surface's 10 angle in relation to the vertical center axis composes the limit for the spindle's movement in relation to the base part 4.
  • the base is furthermore provided with ribs for supporting the cover, which is shown in fig. 1.
  • Fig. 2B shows the base part 4 seen from above, where the ribs 9 clearly appear, and where the sealing material 8 and 6 between the base and the cover lid is clarified.
  • Fig. 3 shows a machine foot where the spindle 1 is turned in relation to the base part 4 in an angle shown by 12, but where there is still optimum sealing between the force transmitting disc/sleeve 3 and the base part 4, so that the hygiene properties are secured no matter the size of the angle 12.

Abstract

L'invention concerne un pied de machine et un procédé de support de machines et de dispositifs. L'invention permet de produire un pied de machine pour une application donnée de sorte que le produit peut être utilisé dans des environnements qui présentent des exigences d'hygiène strictes, notamment, par exemple, dans des hôpitaux et dans des institutions de fabrication de produits alimentaires, y compris dans des abattoirs. Une caractéristique spéciale de l'invention est que les forces de la base de machine vers la surface de montage au niveau du pied de machine sont transmises depuis la broche, montée dans la machine, qui est supportée, vers la base du pied de machine via un manchon ou une bague, qui exerce une pression vers le bas sur le dessus de la partie de base. Ainsi, plus l'espace/écartement entre la broche et la base devient petit, plus la force est transmise. Cela entraîne le fait que l'étanchéité et par conséquent la résistance à la pénétration de poussières et de bactéries augmente avec la charge sur le pied de machine. Le pied de machine est par conséquent spécialement approprié pour l'application dans des environnements présentant des exigences élevées en termes d'hygiène. L'invention permet en outre de réduire au minimum la complexité du procédé de fabrication ainsi que la consommation de matières et par conséquent le coût de production total ainsi que le poids du pied de machine.
