Definitions

  • the invention relates to an electromechanical time switch with interchangeable switching disks, which can be programmed individually, in particular with a daily or weekly program, and are accordingly driven in rotation at different speeds, with a time-controlled drive for the respective switching disk, which has a drive shaft with a pinion arranged on one side reaches through the transmission board behind the switching disc and engages with a ring gear on the respectively arranged switching disc.
  • a time-controlled drive unit that is identical in construction for all the provided switching disks, in particular together with the contact arrangement, which is acted upon by the respective switching disk and can be manufactured with the mechanical and electrical installation devices. It is only during final assembly in the factory or only when the time switch is used that the decision is made as to which type of switching disk and with which program is to be placed on the time switch. It should be ensured that the technical outlay for such a switching disk which is universal, in particular programmable with a daily or weekly program The drive unit that can be equipped is not larger than that of a normal daily or weekly program timer.
  • EP-PS 0 051 262 discloses a multi-range program switching mechanism with a mechanical drive unit driven by a motor for at least two different rotational speeds of the drive of a detachably mounted mechanical program carrier for controlling mechanical and / or electrical or electronic switching devices by the Sides or surfaces of the program carrier arranged switching cams, switching tabs or other control means known.
  • a drive shaft with a pinion arranged on one side extends through the transmission board and comes into engagement with a toothed ring of the respectively arranged switching disk.
  • the drive shaft with the pinion is arranged eccentrically to the bearing axis of the switching disc.
  • the invention has for its object a technically simple and economical solution for a drive unit with at least two drive shafts rotating at different speeds, in which the pinion on the drive shafts, in particular with regard to the number of teeth and / or the module, is always the same and the drive speed required for a specific switching disc can be provided without any problems .
  • Fig. 1 shows a time switch in a housing 12 with a recessed gear plate 1 of the drive unit with at least two provided drive shafts 2 and 3, which are arranged eccentrically to the bearing axis 9 of a switching disc 5 and which are provided with coaxial blind holes 7 or bolts 8 are.
  • 13 denotes a bearing ring running coaxially with the bearing axis 9 for the switching disk removed in this figure.
  • 14 denotes the switching star of a contact arrangement, not shown.
  • the front ends 15 of the drive shafts 2, 3 are arranged sufficiently flat on the side of the transmission board 1 adjacent to the switching disk 5 to the surface 16 of the transmission board 1 there.
  • 6 designated the pinion, which is attached to one of the drive shafts 2, 3.
  • 17 shows the ring gear on the switching disc 5, with which the pinion 6 is engaged.
  • the switching disc 5 is mounted with a coaxial bearing flange 18 on the bearing ring 13 on the transmission board 1.
  • 19 denotes a pointer mechanism in the center of the switching disk 5, which is arranged sunk there.
  • the switching disk 5 can also be axially limited, detachably fastened by means of this pointer mechanism 19. Instead of this pointer mechanism 19, a screw fastening can also be provided to secure the position of the switching disk 5.
  • the switching disk 5 can also be mounted on a bearing axis 9, not shown in this figure, indicated in FIG. 1.
  • FIG. 3 shows the reversible pinion 6 with a coaxial profiled bolt 10, which in particular has a square cross section and which can be inserted into a blind hole 7 with a corresponding cross section in the drive shafts 2, 3, as shown in FIG. 2.
  • a profiled hole 11, in particular a square cross section, on the pinion 6 can also be provided, as shown in FIG. 4.
  • the drive shafts 2, 3 are provided with coaxial profiled bolts 8 arranged on one side, as shown in FIG. 2.
