Definitions

  • the present invention relates to a force cell arrangement for compressed air radial motors, with a plurality of force cells arranged in a rosette-like manner, approximately flat in the depressurized state and provided with air connection means for mutual inflation, which are formed by welding two plastic foil sheets along the cell peripheries.
  • the object of the present invention is the further development of a power cell arrangement of the aforementioned type, such that it provides a multiple in terms of performance and durability compared to the previous designs, which allows optimal results on a pneumatic radial motor with regard to starting behavior, high torque, maximum power, more load-independent Speed u. To achieve.
  • an infinite, rubber-elastic cord which is inserted between the two plastic foil sheets and extends near the center of rotation in a star-shaped arrangement, extends along the cell peripheries, the two plastic foil sheets on both sides of the cord and this completely are welded together.
  • each individual cell is reinforced almost all around by the rubber-elastic cord, the cord absorbing practically all previously effective peripheral forces, which leads to an optimal bellows behavior of the cell, with which its lifespan and functionality reach dimensions not previously assumed.
  • the power cell arrangement according to the invention can be easily manufactured according to the rules of mass production and is thus available to users in any quantity.
  • star-shaped elevations which are located near the center of rotation and are caused by the rubber-elastic cord, can form a form-fitting entrainment connection.
  • the present invention further relates to the use of the force cell arrangement according to the invention in a compressed air radial motor with a rotating flat support disc and a conical support disc carried by the drive shaft, between which the force cell arrangement is located.
  • the star-shaped elevations of the force cell arrangement which are located near the center of rotation and are caused by the rubber-elastic cord, are lowered into corresponding grooves in the end face of the flat support disk in order to produce a positive rotary connection.
  • the force cell arrangement according to FIGS. 1 and 2 here comprises three, in the form of a rosette, approximately flat in the depressurized state, for mutual inflation with air connection means 5,5 'provided with force cells 4,4', 4 ⁇ , which by welding two plastic film sheets 1 and 2 are formed along the cell peripheries.
  • the cross section of the cord 3 can be any.
  • the cord 3 can preferably be produced by punching out, which then results in a rectangular cross section. This does not affect the ability of the cord to balance forces on the cell.
  • known pneumatic radial motor comprises two, usually easily separable housing parts 10,10 ', in the chamber of which a rotating flat support plate 11 extends, the axis of rotation 12 with a drive shaft 13 one of the Taper of a conical support disk 14 connected to the drive shaft 13 includes a corresponding angle.
  • the power cell arrangement according to the invention is supported, the star-shaped elevations 3 'located near the center of rotation caused by the rubber-elastic cord 3' being lowered into corresponding grooves 15 in the end face of the support plate 11, which results in a radially enlarged positive-locking rotary connection between Load cell arrangement and flat support plate 11 ensured.
  • the force cell arrangement is still only in operative connection with the conical support disk 14.
