Definitions

  • the invention relates to a drive device for a hoist, in particular for an elevator, with a motor, a transmission, a braking device and a housing.
  • Such a drive device is known from EP 706 968.
  • the one in this scripture shown drive device has a small structure Length and generates low inertia forces.
  • the engine and the transmission can be cantilevered to the brake housing serving as a stand be the only component on the fundsment got to.
  • This solution has proven itself in itself, but is desirable a further design simplification in such a way that it becomes (possibly extremely) more compact Design shorter assembly times when assembling the drive unit and / or when installing the drive unit in an elevator.
  • the invention aims to solve this problem.
  • a drive device is created which is distinguished from the generic prior art by the fact that in the housing of the drive device both the motor and the braking device (preferably including the mounting of the continuous drive shaft ) are housed together. This is not the case with EP 0 706 968, because here the motor is flanged together with its housing to a separate brake housing, which also serves as a stand for the entire drive unit.
  • the invention takes a different path because it saves "one of the housings and instead integrates the brake and motor into a single construction.
  • the particular advantage of this construction results from the simplification of the assembly of the drive device in the factory and the reduced installation space required in an elevator.
  • the installation space is often retrofitted When replacing a worm gear, a planetary drive must fit in the axial direction of the traction sheave, ie it must be aligned 90 ° to the existing gear.
  • the structural design further simplified and shortened in that at least one in the housing (preferably essential) part of the transmission (planetary or cyclo or spur gear) is arranged as a built-in or built-in gear, so that the housing in this part also forms the gear housing.
  • a separate gearbox can therefore be omitted in this area (preferably only one housing cover is left intended).
  • Brake and fan can be summarized particularly simply in that on the brake body Fan blades can be formed in the manner of a drum or disk.
  • Fan blades can be formed in the manner of a drum or disk.
  • a (pot-like) rotor sleeve on the brake drum is also used arranged (e.g. molded).
  • stator winding protrudes significantly into the interior of the brake drum in order to reduce the overall length.
  • the combination of brake drum and rotor sleeve to form a casting / molded part leads to a reduction in machining and assembly costs and to a shortening of the drive shaft With some sizes, the support bearing at the shaft end can even be omitted, which further reduces the costs and the overall length.
  • a permanent magnet motor with rotor and stator as the motor, which (in relation to the other dimensions of the drive device) has a flat design and opposite "of the brake drum (also infinitely variable) on the shaft.
  • the rotor of the permanent magnet motor is arranged on the (pot-like) outer wall of the brake drum and the stator on the inner wall of the housing.
  • the brake drum thus serves as a simultaneous support sleeve for the Rotor, which opens up the possibility of reducing the overall diameter and the height of the drive, which is advantageous, for example, in applications in which the Overall length "of the drive device is less critical. Above all, high torque with a small rotor diameter can be realized in this way.
  • Another type of realization of a permanent magnet drive is an extremely narrow motor (disc motor) on a correspondingly enlarged Diameter compared to the brake drum on the elongated cast body arranged.
  • the new housing construction results in a clear one Reduction of assembly time and a structural simplification with the consequences of one Material savings and a reduction in size (for example by Saving of elements such as shaft screw connection, final bearing of the drive shaft and fan unit).
  • Fig. 1 shows schematically a drive unit for an elevator with the basic components Gearbox 2, brake 4 and motor 6, which are coaxial on a drive shaft 7 are arranged.
  • the housing 8 encloses the brake 4 and the motor 6 and part of the transmission and carries a traction sheave, not shown for the ropes of an elevator.
  • the housing 8 is on a not shown Anchored foundation.
  • the traction sheave can either be on the output flange 2a or be mounted / mounted on the output shaft 2b.
  • the brake 4 has a brake body in the manner of a cast brake drum (10) to the fan blades 12 and a rotor sleeve 14 for the rotor 16 of the electric motor 6 (with rotor 16 and stator 18) are integrally formed (see also Fig 3a).
  • the stator windings engage in the brake drum 4 (use as motor power) one, which has ventilation openings on its axial outer surface, for example 19 (Fig. 3a). If the permanent magnet motor turns, turns the brake drum 10 together with fan blades and the molded fan blades 14 realize the cooling of the electric motor 6 in an uncomplicated manner (see the air flow indicated by arrows).
  • a permanent magnet motor as the electric motor 6 to use, which in a particularly flat design like a Disc motor is running.
  • Fig. 2 she corresponds in its function to Fig. 1, but allows a shorter overall length (in Direction of the drive shaft) while increasing the motor diameter.
  • the rotor 16 of the permanent magnet motor is stepped here outwardly offset neck 20 (with a larger diameter than the diameter the drum 10) on the outer wall of the brake 4 'and the stator 18 again arranged on the inner wall of the housing 8.
  • the case points a clear gradation 22 to accommodate the engine, but is in braking and Engine area formed in one piece.
  • a foot element 23 enables Installation on the foundation (not shown).
  • FIGS. 4 and 5 largely corresponds in its structure 1, but forms a section A of the Housing 8 here is a part of the otherwise separately required gear housing.
  • the continuous drive shaft 7 is (see enlarged detail of Fig. 5) only stored in the carrier housing (bearing 24).
  • the transmission 2 is so no longer an independent unit, but is an add-on part in the support housing 8 integrated.
  • the interior of the stepped rotor is also 16 used to increase the engine power, with an additional stator 18a is arranged on the housing cover 25 (Fig. 2).
  • the brake drum can also be used be infinitely variable (not shown).
