Definitions

  • the invention relates to a gearless drive device for a hoist according to the preamble of claim 1.
  • a drive device for a hoist is known from EP 0 706 968 which has a simple structure and a short overall length, whereby low mass forces are generated.
  • the engine and the transmission can be cantilevered to the brake housing serving as a stand be the only component on the foundation got to.
  • This solution has proven itself in itself, but is desirable a further constructive simplification of the way that see (if necessary extremely) compact design, shorter assembly times for assembling the Drive units and / or when installing the drive unit in an elevator result and that components are saved.
  • the invention aims at this Solve a problem.
  • a drive device is created which is distinguished from the 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 the subject matter of 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 in a single construction, whereby the through shaft is advantageously not supported by means of the gearbox, but by means of a bearing sleeve which is inserted into an end opening of the housing and attached to it.
  • Another advantageous variant of the invention also integrates the brake and Fan and / or rotor sleeve into one unit.
  • the housing can with this solution according to the type of claim 1 or one of the other subclaims or be designed according to conventional construction.
  • Leave the brake and fan can be summarized particularly simply in that on the brake body Type of drum or disk fan blades can be molded.
  • a (pot-like) rotor sleeve is also arranged on the brake drum (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 a shortening With some sizes, the support bearing at the shaft end can even be omitted, which further reduces the costs and the overall length.
  • the motor an electric motor with at least one stator and at least one rotor 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 electric motor is arranged on the (pot-like) outer wall of the brake drum and the stator on the inner wall of the housing Rotor, which opens up the possibility of reducing the overall diameter and the shaft 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.
  • the stator winding of the motor can advantageously protrude into the brake drum in order to save overall length.
  • the electric motor can be extended axially the brake drum, especially in a step-like approach, and the stator be arranged radially within the approach in the housing.
  • the stator be arranged radially within the approach in the housing.
  • a mounting bracket advantageously serves to fasten the housing, which is attached to a suitable substructure, and a concave receptacle has, in which the rotationally symmetrical on the outside Housing is included.
  • the housing has in a radial plane of the housing wall Slots through which pads or pad carrier the shoe brake lever are adjustable on the outside of the brake drum. Have these slots a slightly larger longitudinal extension than the brake pads, so that the housing in certain limits can be rotated about its longitudinal axis. But it is also conceivable that segment slots are provided in the radial plane of the housing, in which the brake pads or brake pad carrier after a corresponding rotation of the housing are insertable.
  • the new housing construction results in a clear one Reduction of assembly time and a structural adaptability and constructive Simplification with the consequences of saving material and reducing it the size (e.g. by saving on elements such as shaft screw connections, Final bearing of the drive shaft and fan unit as well as savings the gear unit).
  • a gearless Drive device for a hoist that the motor or motors are mounted directly on the drive shaft and that the brake drum on the Traction sheave is integrally formed, with the motor housing partially on the outside spreads.
  • This construction offers a particularly compact design the drive device.
  • Fig. 1 shows schematically a drive unit 1 for an elevator with the basic components Traction sheave 2, brake 4, motor 6, coaxial on a drive shaft 7 are arranged.
  • the housing 8 encloses the brake 4 and the motor 6 and carries the traction sheave 2 for the ropes (not shown) of an elevator.
  • the housing 8 is anchored on a foundation, not shown.
  • the Traction sheave 2 is mounted on the output flange 3 of the shaft 7.
  • the brake 4 has a brake body 10 in the manner of a cast brake drum on which the fan blades 12 and a rotor sleeve 14 for the rotor 16 of the electric motor (with rotor 16 and stator 18) are integrally formed (see also Fig. 3).
  • the stator windings engage in the brake drum 4, which, for example has ventilation openings 19 on its axial outer surface (see FIG. 3). If the rotor 16 rotates with the shaft 7, the brake drum also rotates 10 together with fan blades 12, and the molded fan blades 12 realize in a more uncomplicated manner Way, the cooling of the electric motor 6, which is shown schematically by arrows is indicated.
  • the air flow can exit the housing through slots 5.
  • 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 The function corresponds to the subject of FIG. 1, but allows one shorter overall length (in the direction of the drive shaft) with simultaneous enlargement of the motor diameter.
  • the rotor 16 of the permanent magnet motor is here on a step 20 offset to the outside with a larger diameter than the diameter of the drum 10 on the outer wall of the brake 4 ' and the stator in turn arranged on the inner wall of the housing 8.
  • the Housing has a clear gradation 22 to accommodate the engine but integrally formed in the brake and engine area.
  • a foot element 23 enables assembly on the foundation, not shown.
  • FIG. 2 there is a further motor unit consisting of rotor 16a and stator 18a provided, either as an alternative to that shown in the upper area of FIG. 2 Motor unit or can also be provided.
  • the rotor 16a on an axial extension 20a of the brake 4 '(similar to approach 20) stored while the stator 18a is mounted on a carrier 32, which in turn is mounted on the housing cover 25 of the housing 8.
  • Reference number 33 denotes a tachometer, which is either on the inside of the housing cover 25 or can be attached to the outside. He has no supporting function for the continuous shaft 7, which exclusively by means of a bearing sleeve 27 and bearings 34 and 35 in a front housing opening 36 of the housing 8 is mounted.
  • FIG. 5 are on the rotor sleeve 26 or on the Inside the housing 8 two motors mounted in a row to increase performance to achieve.
  • the stator winding in relation to FIG. 5 the right stator in turn engages in the brake drum of the brake 4.
  • the motor housing 8 which is rotationally symmetrical on its outside is, by means of a mounting bracket 29 on a not shown Foundation supported.
  • This mounting bracket 29 has a concave receptacle 28, which enables the housing 8 to be rotated about its longitudinal axis, whereby the assembly of connection cables is made considerably easier.
  • the brake shoe levers 30 have brake pads 31, which reach through slots 37 in the housing and thus against the The outer circumference of the brake drum of the brake 4 can be adjusted.
  • the slots 37 are somewhat larger than the corresponding ones in their longitudinal extent Brake pads 31 of the brake shoe lever 30 formed so that the housing in certain limits can be rotated about its longitudinal axis. But it is also conceivable that slot segments are provided which correspond to the corresponding brake pad segments the brake shoe lever after turning the housing into a suitable one Position can be assigned.
  • 6 is the traction sheave 2 not shown.
  • the motors 6 ' are arranged directly on the drive shaft 7' while the brake drum 10 'of the brake 4' is directly molded onto the traction sheave 2 ' is, and the housing 8 'or 8' 'partially overlaps.
  • the brake shoe lever 30 ' acts directly on the brake drum with its brake lining 31' 10 'a.
  • the rotor sleeve has been dispensed with.
  • the fan blades 12 can be operated at very low speeds (about 150 to 400 rpm) can be dispensed with, as the effect, if not a corresponding one Wing area is available is small. Should be built very compact, the wing area would be relatively small and would have little effect. In the present exemplary embodiment according to FIG. 7, use was therefore made the rotor sleeve waived.
