Definitions

  • the present invention relates to a drive disc for the tool of a machine for preparing and / or maintaining floors.
  • machines for preparing and / or maintaining floors comprising a motor capable of driving in rotation at at least one rotary tool via a drive shaft at least substantially orthogonal to said tool, said tool being connected to said drive shaft by a drive disc connected, in the vicinity of its external periphery, to the tool and, in the vicinity of its center, at the drive shaft, and allowing a relative inclination of limited amplitude of the axis of rotation of the tool relative to said drive shaft.
  • said disc is made of an elastic material (metal or rubber), so that the degree of freedom of the tool parallel to the axis of the tool is limited by the elasticity of the disc and that this results in defects in the coplanarity of the tool with respect to the ground. As a result, the treated surface is irregularly attacked by said tool, so that it cannot be perfectly uniform.
  • document EP-A-0 388 273 describes such a drive disc comprising a circular diaphragm made of a non-elastic material which is flexible perpendicular to its plane, but which is rigid in its plane.
  • said diaphragm consists of a canvas of rigid synthetic material in rotational shear.
  • a fabric can for example be of the type used for the production of conveyor belts. She can be made of crossed fabrics of polyester fibers coated with polyvinyl chloride.
  • the disc can transmit the torque from the drive shaft to said tool, so that the latter is rotated. Furthermore, since the material of the diaphragm is flexible perpendicular to its plane, such a disc allows, in particular at start-up, a "decoupling" of the tool from the rest of the machine, facilitating the start-up of the tool, and the maintenance of the latter perfectly parallel to the soil to be treated, during treatment. In addition, this disc allows a distribution of forces or forces on the tool, which allows lateral movement of the machine.
  • the object of the present invention is to eliminate vibrations at reduced speed.
  • the drive disc intended for a machine for preparing and / or maintaining floors of the type comprising a motor capable of driving in rotation at least one rotary tool per l intermediate of a drive shaft, said drive disc comprising a rigid circular plate and a circular diaphragm, said circular diaphragm being connected, in the vicinity of its external periphery, to said rigid circular plate and, in the vicinity of its center, to the drive shaft, and being made of a material which is flexible perpendicular to its plane , but which is rigid in its plane, said tool being fixed on said rigid circular plate on the side opposite to said diaphragm, is remarkable in that the cavity formed between said rigid circular plate and said diaphragm is sealed and contains a fluid tending said diaphragm.
  • said fluid was advantageous for said fluid to be a liquid and for the density of said liquid to be higher the lower the nominal rotation speed of said disc.
  • said fluid which completely eliminates vibrations at 400 rpm, allowed certain vibrations to remain at 200 rpm, which were eliminated by replacing the water with glycerine.
  • the Applicant has also noted in this connection that, in addition to the density of the liquid, the quantity of liquid contained in said cavity was also a parameter for adjusting the elimination of vibrations at a given speed.
  • said connecting means allow easy mounting and / or dismounting of said drive disc on the machine shaft.
  • complementary connection means carried by said drive shaft to form a removable connection with wedging.
  • the rotary tool comprises, or is constituted by a disk of fibrous material
  • said rigid circular plate comprises, on its face opposite to said diaphragm, hooks for the attachment of said material disk fibrous.
  • Figure 1 is a diametrical sectional view of an embodiment of the drive disc according to the present invention.
  • Figure 2 is a top view of the disc of Figure 1.
  • Figure 3 is a sectional view similar to that of Figure 1, the motor drive shaft being in an inclined position relative to said tool.
  • the drive disc 1, according to the present invention and shown in Figures 1 to 3, is intended to be mounted on a machine for the preparation and / or maintenance of floors, this machine comprising a motor (not shown) capable of driving a rotary tool 2 via a drive shaft 3.
  • the drive disc 1 comprises a rigid circular plate 4 and a circular diaphragm 5.
  • This diaphragm is made of a flexible material perpendicular to its plane, but rigid in its plane, such as for example a canvas of rigid synthetic material in rotational shear.
  • a fabric can for example be of the type used for the production of conveyor belts. It can be made of crossed fabrics of polyester fibers coated with polyvinyl chloride.
  • the circular diaphragm 5 is made integral with said rigid plate 4, in leaktight manner, for example also thanks to an auxiliary membrane 9 applied against said rigid plate 4, in the vicinity of outer peripheries of said diaphragm and said rigid circular plate.
  • a female connecting flange 7 is provided to cooperate with a male flange 8 secured to the free end of the drive shaft 3.
  • this male flange 8 is shown in dotted lines, like the shaft 3 of which it is united.
  • the male and female flanges 7 and 8 form a lug connection by rotation and wedging.
  • a sealed cavity 10 In this sealed cavity 10, is contained a fluid, in particular a liquid capable of slightly stretching said diaphragm 5, as shown in FIG. 1.
  • the soil treatment machine is designed to drive the rotating disc at a nominal speed of 400 rpm, it is advantageous for said liquid to be water.
  • the diaphragm 5 remains slightly taut (see Figure 1) in the manner of a hot water bottle, while the inclination of the tool 2 relative to the shaft 3 is free, but damped, as shown in figure 3.
  • the rigid circular plate 4 has, on its face opposite the diaphragm 5, projecting hooks 11 capable of penetrating into the fibrous material of the tool 2.
  • the tool has a central recess 12 capable of cooperating with a projection 14 carried by the face of the rigid circular plate on which said hooks are provided. 11.
