Definitions

  • ABSTRACT A gear box or mechanical speed variator particularly for liquid distributing measuring apparatus comprising a set of nine crown wheels arranged concentrically and whose number of teeth varies in the ratio of 1 to 9, said set of wheels cooperating with an assembly of sliding gears, each one of said gear selectively coming into engagement with any one of the gears of the multiple gear device.
  • the present invention relates to a gear box or mechanical speed variator, of the type comprising a multiple gears device cooperating with an assembly of sliding gears, more particularly intended for equiping hydrocarbon distributor metering appliances, so as to ascertain the price of the quantity of liquid delivered as a function of the unit price of this liquid.
  • An ordinary variator generally comprises a multiple gears device made of a conical piling of gears integral with the input shaft, and an assembly of sliding gears, whose rotations are transmitted to the output shaft, being selectively made to engage with one of the gears of the cone, according to the ratio required to be given to the transmission.
  • the regulating of the output speed of the variator as a function of the unit price is done manually by means of three sliding gears, the liquid unit price being often expressed by three significant figures (units, tenths, hundredths).
  • Each of these sliding gears meshes with one of the nine gears of the cone whose numbers of teeth are respectively proportional to the FIGS. 1, 2, 3, 4, 5, 6, 7, 8 and 9.
  • the first sliding gear, called unit sliding gear will mesh with the first gear of the cone which comprises, for instance, 12 teeth
  • the second sliding gear, called tenths sliding gear will also mesh with the first gear of the cone
  • the third sliding gear, called hundredths sliding gear will mesh with the fifth gear of the cone which comprises 60 teeth.
  • a mechanical speed variator particularly for a liquid distributing measuring apparatus, of the type comprising a multiple gear device fixed on the input shaft, cooperating with an assembly of sliding gears, each of said gear, whose rotation speeds are added on the output shaft, selectively come into engagement with any one of the gears of said device, said variator being characterized by the following points.
  • Each crown wheel has a number of teeth that are the multiple of the number of sliding gears, and that of the largest diameter is provided with adjusting marks, of a number equal to the number of sliding gears, evenly spaced out on its periphery, so that when any one of these adjusting marks is brought in front of a fixed mark, the teeth of all the wheels are aligned according to directions in vertical coincidence with the axes of the shafts supporting the sliding gears 5.
  • the set of the nine crown wheels is made in the shape of a moulded assembly 6.
  • a helicoidal toothed wheel is mounted transmitting the rotation speed of the sliding gear to an adding device 7.
  • Each fork has a finger placed in the groove of a lug forming part of a rack, so as to drive said rack from which the control takes place of a drum displaying the unit price.
  • FIG. 4 is a section of one of the forks, along the line lV-lV of FIG. 3.
  • a speed variator l is diagrammatically shown and a quantity and price recorder 2, fixed one on the other by means of a screw 3.
  • the input shaft 4 of the variator 1 on which a coupling 5 is mounted directly receives its movement from the volume measurer M.
  • the upper end of the shaft 4 drives toothed wheels 40 and 41 from which drums 6 are driven for displaying volumes and are seen on each face of the recorder 2.
  • the toothed wheel 7 of the variator output 1 revolves at a speed proportional to the volume of liquid delivered and drives in toothed wheel 42 from which are controlled the drums 8 for displaying prices.
  • the drums 9 displaying the unit price, arranged at the lower part of the recorder 2, are driven as will be explained hereafter, by means of forks controlling sliding pinions or gears.
  • the variator l is shown housed in an assembly of two superimposed casings a lower casing 10 fixed on a plate 11 by screws 12, and an upper casing 13 fixed on the casing 10 by screws 14.
  • a disc 15 is pinned inside the casing 10, having nine concentric toothed tracks on one face.
  • the discs and tracks are made in the shape of a moulded assembly.
  • the number of teeth of each annular track forming a toothed wheel is respectively proportional to the FIGS. 1 to 9.
  • the smallest track or wheel 16 will have twelve teeth, for instance, and the largest 17, 108 teeth.
  • Shafts l8, l9 and 20 places radially at to each other, in the same horizontal plane, revolve at one of their ends in bearings of a boss 10a of the casing 10.
  • Each of these shafts carries a sliding pinion, namely the sliding pinion 21 of the units, the sliding pinion 22 of the tenths, and the sliding pinion 23 of the hundredths.
  • the rotation movement of the threaded rods 47, 48 and 49 I drives the forks 44, 45 and 46 in translation as well as'the sliding pinions 21, 22 and 23 which can thus engage with any of the nine tracks of the dies 15.
  • the correct positioning of said forks is obtained by means of bolts 53 (FIG. 4) thrust by springs 54 into notches 55 of the casing 10.
  • the action of the springs such as 54 on the forks 44, 45 and 46 makes the forks bear on lugs such as 104 of the casing 10, by thus preventing any rotation movement of said forks owing to rotating of the threaded rods 47, 48 and 49.
  • the spindle 34 drives by means of the toothed wheels 35, 36 and 109 the planetary 110 of the differential 37.
  • the spindle 33 drives by means of the toothed wheels 11], 112, 113, the planetary 114 of the differential 37
  • the satellite holder 116 proportionally adds the speeds of the planetaries 110 and 114, Le.
  • the spindle 32 drives by means of the toothed wheels 118, 119, 120, the planetary 121 of the differential 38.
  • said alignment means comprises three radial passages arranged at [20 with respect to each other, said passages being formed by aligning the spaces between two teeth on each of said gear wheels.
