Definitions

  • the invention relates to a drive unit for a hoist, especially for an elevator, according to the preamble of the claim 1.
  • a known drive unit of this type (WO 89/11436) there is the drive shaft passed through the brake housing from three parts, which are connected by two couplings are connected.
  • One of the clutches is used by one Brake disc carrier formed on which a brake disc in one piece is molded.
  • the tripartite wave with the two Shaft couplings, one of which also has a length compensation is provided, increase the overall length of the drive unit, increase the mass of the rotating parts and favor the occurrence of vibrations.
  • the invention has for its object a drive unit of the type mentioned in such a way that they with a simple construction has a short overall length and low Generated forces.
  • the motor and the transmission are preferably self-supporting flanged to the brake housing on both sides. They form thus a unit that can be pre-assembled and none Alignment work requires more when installing the hoist, but as the only component to be fixed to the foundation got to. Depending on the design of the gear unit, this can also be on the output side flanged to the brake housing and on the drive side be connected to the engine.
  • the brake can be designed as a drum or disc brake or, if necessary, also according to other construction principles be constructed.
  • the parts absorbing the braking forces become either on the brake housing or on a separate one Carrier set.
  • the brake body e.g. the brake drum or brake disc
  • the brake body is preferably by means of a flange or a cone coupling attached to the through shaft so that a partial or complete replacement without excessive Effort is possible.
  • the accessibility will continue improved that the brake housing has openings, through which the brake is accessible.
  • a planetary gear is used as the gear, this in an advantageous manner on the side facing away from the engine Flanged side of the brake housing.
  • the outer jacket of the Planetary gear can then cantilever into the elevator shaft Rope pulley designed for the ropes of an elevator be, which results in a further saving in length.
  • the type of flange mounting according to the invention enables the use of others in an advantageous manner Gear types such as Helical gear, backlash-free precision gear and combination gear.
  • Gear types such as Helical gear, backlash-free precision gear and combination gear.
  • the drive shaft is a space-saving version of a pulse generator be stored, which are used for controlled drives can.
  • This pulse generator can be in the space of the motor housing be integrated or from the motor drive shaft bearing be educated.
  • Fig. 1 shows schematically a drive unit for an elevator with the basic components gear 1, brake 2 and motor 3, which are arranged coaxially.
  • the gear 1 is a planetary gear trained and wears on his outer jacket a traction sheave, not shown, for the ropes of an elevator.
  • a brake housing is designated, which is integral with a rigid base plate 11 is connected.
  • the base plate 11 continues until under engine 3 and is not on one anchored foundation shown.
  • the planetary gear 1 is on with its fixed part the left side in Fig. 1 of the brake housing 8 flanged. In the same way, the housing of the motor 3 is on the right Side of the brake housing 8 attached.
  • the rotor 5 of the motor 3, the brake body of the brake 2 and the input part of the planetary gear 1 sit on a common Wave 6, which is a continuous wave through the entire Drive unit runs.
  • a handwheel 7 can be attached for emergency operation become.
  • a pulse generator 13 mounted on the inside of the motor housing cover is supported.
  • the drum or disc trained brake body is by means of a known cone connection fixed on the shaft 6, as shown in Fig. 4a and 4b is shown schematically.
  • the free end of the shaft 6 be accommodated in a support bearing 14, which itself as Pulse generator can be formed.
  • the support bearing or the Free ends of the shaft can be removed by a removable cap 15 be covered.
  • This cap can have a safety contact be provided to ensure that the handwheel is attached, that the drive unit cannot be operated.
  • a drum brake is shown at the brake shoes 12 via lever 9 and a brake cylinder 10 be pressed against the outer circumference of the brake body.
  • 3a and 3b show a disc brake, also with levers 9 and a cylinder 10.
  • Planetary gear can also be a gear with another, known design can be used. It is also there possible to a unit designed as a geared motor flange on one side of the brake housing and onto that the other end of the shaft 6 projecting a pulley to suspend for the suspension cables.
  • the main advantages of the drive unit according to the invention exist in the significantly shortened design due to elimination the clutch and by arranging a continuous Shaft with the bearing of the brake on the shaft nearby of the gearbox or pulley bearing, whereby the centrifugal masses can be reduced and better absorbed and what is provided in the usual constructions Engine support bearings can be omitted.
  • the brake housing can be lateral Have openings through which the brake can be monitored and is accessible so that wear can be observed can and an easy replacement of brake parts is possible.
