Definitions

  • the present invention relates to a drive disc for the tool of a machine for repair and / or maintenance soils.
  • machines for the preparation and / or maintenance of the grounds comprising a motor susceptible to rotate at least one rotary tool by at least substantially through a drive shaft orthogonal to said tool, said tool being connected to said tool drive shaft by a drive disc connected to the near its outer periphery, to the tool and, in the vicinity from its center, to the drive shaft, and allowing a relative inclination of limited amplitude of the axis of rotation of the tool with respect 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 it results from defects in the coplanarity of the tool by report to the ground. As a result, the treated surface is attacked irregularly 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 his plan.
  • said diaphragm consists of a canvas rigid synthetic material in rotational shear.
  • a such canvas can for example be of the type used for making conveyor belts.
  • She can be made of polyester fiber crossover fabrics coated with polyvinyl chloride.
  • the disc can transmit the torque of the tree training tool, so that it is driven in rotation. Furthermore, since the material of the diaphragm is flexible perpendicular to its plane, such disk allows, especially at startup, a "decoupling" of the tool from the rest of the machine, making setting up easier tool path, and maintaining it so perfectly parallel to the soil to be treated, during treatment. In addition, this disc allows a distribution of efforts or forces on the tool, which allows lateral movement of the machine.
  • the object of the present invention is to improve the drive disc of document EP-A-0388 273 for eliminate vibrations at reduced speed.
  • the drive disc intended for a machine for the preparation and / or soil maintenance of the type comprising a motor capable of to rotate at least one rotary tool by through a drive shaft, said disc with a rigid circular plate and a circular diaphragm, said circular diaphragm being connected, in the vicinity of its outer periphery, to said rigid circular plate capable of being connected, near its center, said drive shaft, and being made of a material which is flexible perpendicularly to its plan, but which is rigid in its plan, said tool that can be fixed on said rigid circular plate on the side opposite said diaphragm, is remarkable in that the cavity formed between said rigid circular plate and said diaphragm is sealed and contains a tending fluid said diaphragm.
  • said fluid is a liquid and that the density of said the higher the speed of rotation nominal of said disc is lower. He has for example found that water, which totally eliminates vibrations at 400 rpm, left some vibrations at 200 rpm, which were eliminated by replacing the water with glycerin.
  • said connecting means allow a easy mounting and / or dismantling of said drive disc on the machine shaft.
  • the rotary tool comprises, or else consists of a disc of fibrous material
  • said rigid circular plate comprises, on its face opposite to said diaphragm, hooks for hanging of said disc of fibrous material.
  • Figure 1 is a diametrical sectional view of an example of realization of the drive disc in accordance with this invention.
  • Figure 2 is a top view of the disc of Figure 1.
  • Figure 3 is a sectional view similar to that of the Figure 1, the motor drive shaft being in a 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 repair and / or maintenance floors, this machine comprising a motor (not shown) likely to drive a rotary tool 2 through a drive shaft 3.
  • the disc drive 1 comprises a rigid circular plate 4 and a circular diaphragm 5.
  • This diaphragm is produced in a flexible material perpendicular to its plane, but rigid in its plan, such as for example a canvas of synthetic material rigid in rotational shear.
  • a canvas may for example be of the type used for the production of conveyor belts. It can be constituted crossover fabrics made of polyester fibers coated with polyvinyl chloride.
  • the circular diaphragm 5 is made integral with said rigid plate 4, sealingly, for example also thanks to an auxiliary membrane 9 applied against said rigid plate 4, in the vicinity of the external peripheries of said diaphragm and said rigid circular plate.
  • the male and female flanges 7 and 8 form a lug connection by rotation and wedging.
  • a sealed cavity 10 is formed between the diaphragm 5 and the circular plate rigid 4, in this sealed cavity 10.
  • this sealed cavity 10 is contains a fluid, in particular a liquid capable of slightly tension said diaphragm 5, as shown in figure 1.
  • the rigid circular plate 4 has, on its face opposite to diaphragm 5, projecting hooks 11 capable of penetrate into the fibrous material of the tool 2.
  • the tool has a recess central 12 capable of cooperating with a projection 14 carried by the face of the rigid circular plate on which are provided with said hooks 11.
