  • the brake 5 can with a Hand release lever 13 can be opened manually.
  • the end of one with the Drive axis 41 concentric shaft 25 is from the center of the Brake 5 to the right so far that at this shaft end Handwheel 5 can be plugged on.
  • the shaft 25 den whole drive penetrating so that from the Center of the traction sheave 1 projects a second shaft end 42 and to attach the handwheel 6 on the traction sheave side or to Attaching an additional device, for example a rotary encoder, can serve.
  • the traction sheave 1 is provided with fastening screws 30 Output hub 19 connected, which in turn via coupling pin 14 is operatively connected to a reduction gear 15.
  • the Transmission housing 16 with a transmission front cover 18 forms the left-hand front end of the motor housing 3.
  • Das Gear housing 16 is on the right with a gear rear wall 17 completed.
  • the traction sheave 1 with the driven hub 19 is in the Gear housing 16 rotatable by means of a traction sheave bearing 7 stored, the traction sheave bearing 7 in its function as Heavy-duty bearings, for example, designed as crossed roller bearings is.
  • the motor consists of a gear housing 16 partially enclosing rotor body 8, which the rotor core 9 with the cage winding 10 carries. Radially with respect to the rotor 8, 9, 10 is on the inner wall of the motor housing 3, the stator, consisting of Stator laminated core 12 and stator winding 11 are arranged.
  • the fixed parts are those already mentioned Motor housing rear wall 4, the motor housing 3, the gear housing 16, the transmission housing rear wall 17 and the transmission front cover 18.
  • the parts rotating at engine speed are one on the right on the Motor shaft 25 attached hub 44, which the rotor body 8 with the Rotor laminated core 9 and the rotor cage winding 10 carries.
  • the gear parts include the motor shaft 25, or a first one Eccentric 28 and a second eccentric 29, which on the above Motor shaft 25 between a first shaft bearing 26 and one second shaft bearings 27 are formed and to each other by 180 ° are offset.
  • the two eccentrics 28 and 29 carry a first one Roller bearing 31 on the first eccentric 28 and a second Roller bearing 32 on the second eccentric 29.
  • Via the eccentric 28, 29 and the roller bearings 31, 32 become a first planet disc 22 and a second planet disk 23, each with teeth 34 an internal toothing 21 in the gear housing 16.
  • the Planet gear 34 has a smaller number of teeth than that Internal teeth 21 in the gear housing 16.
  • the planet disks 22, 23 shown in FIG. 3 have a circular shape arranged coupling holes 33 (Fig.2), in which with Support rollers 24 provided clutch bolts 14 grip.
  • This Coupling bolts 14 with the support rollers 24 penetrate the Coupling bores 33 of both planet discs 22 and 23.
  • Die Coupling bolts 14 are from the rotating planet discs 22, 23 via the coupling bores 33 and the support rollers 24 taken along and form the mechanical output of the Reduction gear 15. You are direct in this function, or connected to the drive pulley 1 via the output hub 19.
  • the Diameter of the coupling bores 33 in the planet disks 22, 23 are twice the eccentricity of the eccentric 28, 29 larger than that of the support rollers 24, so that Reduction gear 15 without clamping, but also without unnecessary play running.
  • the reduced speed of the clutch pin 14, the clutch hub 19 and the traction sheave 1 results from the difference in the number of teeth between the planet discs 22, 23 and the internal teeth 21 in Gear housing 16, the number of teeth of Planetary disc toothing 34 is smaller than that of the Internal teeth 21 in the gear housing 16.
  • Das Gear ratio is calculated from the number of teeth on the Internal toothing 21 divided by the difference in the number of teeth.
