Definitions

  • the invention relates to a traction sheave shaft conveyor with an electric motor, the rotor is connected to a cylinder jacket of the traction sheave and the stator is arranged on a mounted in bearing blocks axis, wherein the motor disposed within the cylinder jacket and between the side shields of the traction sheave in a cavity is, which can be acted upon by cooling air via axial cooling air passage openings for cooling the engine.
  • the one-piece axle is forged from solid steel. Except for two forged flanges for attachment of the stator by means of releasable clamping ring connections, the one-piece axis has a continuous diameter profile.
  • the cooling passage openings are arranged in ventilation rings, which are located between the one-piece axis and the rolling bearings.
  • the cylinder jacket of the traction sheave is supported on the side shields of the traction sheave on the rolling bearings.
  • the one-piece, made of solid material axis has no debilitating holes and can therefore be made relatively slim. Furthermore, the execution of the axle made of solid material is less expensive and less expensive than the execution of the axle as a hollow axle.
  • a disadvantage of the known traction sheave shaft carrier is the complex attachment of the stator to the two forged flanges via detachable clamping ring connections.
  • stator attachment of the stator to the two clamping rings requires a relatively large amount of space within the limited by the cylinder jacket and the side shields traction sheave.
  • the high space requirement of the stator mounting can impair maintenance and testing work.
  • the manufacture of the stator must be tailored to the manufacture of the one-piece axle to account for the tolerances of the two flanges, the ferrules and the stator connections.
  • the one-piece axis is formed at both ends as a square. This quadrilateral engage in corresponding receptacles in the bearing blocks. At the four-edge clamping pieces are pressed with clamping screws, which in turn engage in the bearing blocks.
  • This axle mounting in the bearing blocks is expensive. Furthermore, it comes in load changes to movements of the square edge in the images of the bearing blocks and occasionally to noise.
  • the invention is therefore based on the object to provide a traction sheave shaft carrier of the type mentioned above, while maintaining the advantages of a solid material axis requires a less expensive construction, in which the stator easier and cheaper perform and fix it to the axle and movements of the axle in the bearing blocks and thus a noise does not occur.
  • a traction sheave shaft conveyor of the type mentioned above in that the axis is formed of two sub-axes, each consisting of solid material, on each sub-axis an outer flange and an inner flange attaches to the end face, between the two inner flanges a holding element is clamped, on which the stator is fixed, and the two outer flanges are fixed to the bearing blocks.
  • the axis consists of two, preferably matching constructed sub-axes of solid material.
  • the stator is fixed on the clamped between the two inner flanges retaining element, in particular in the form of a web plate.
  • the previously required according to the prior art connection of the stator via two clamping rings and the associated disadvantages completely eliminated.
  • the two inner flanges, which join the sub-axes with screws and nuts, also clamp the holding element for the stator, so that the assembly is considerably simplified.
  • Another advantage of the invention is that the holding element for the stator and the sub-axes can be designed and manufactured independently of each other.
  • the production does not require the consideration of manufacturing tolerances of the axis spaced apart flanges and clamping rings; There are only the tolerances of the bolt holes in the inner flanges and the aligned holes in the particular designed as a web plate holding element to consider.
  • the steel construction of the preferably integrally formed with the holding member stator can be completely processed due to the one-piece design before installation, since a consideration of the tolerances of several acting on the laminated cores of the stator holding elements is not required. Meanwhile, the laminations of the stator are located between two spaced-apart Brackets that are connected to the axis, the distance between the brackets to each other changed when screwing the laminated cores, which leads to connection problems of the brackets on the axle.
  • stator can be radially adjusted to the support member.
  • the two sub-axes are each secured with their outer flanges on the bearing blocks.
  • This connection eliminates the need to mill a square at the end of the production of the sub-axes.
  • the screws on the two outer flanges contribute to a more even load transfer in the support blocks. Relative movements between the sub-axes and the support blocks are avoided. As a result, no disturbing operating noise and technically disadvantageous movements occur.
  • the loads occurring are removed by shearing stress of all screws of the flanges.
  • Another constructive advantage of the flange connections between the sub-axles and the support blocks is their good predictability and verifiability for maintenance purposes.
  • each sub-axis surrounds a bearing base, wherein at least one axial cooling air-through opening is arranged in each of the two bearing sockets.
  • the cooling air is supplied to one of the two bearing pedestals, flows through the air gap between Rotor and stator and escapes from the cavity via cooling air passage openings in the other of the two bearing base.
  • each one of the side shields of the traction sheave is rotatably supported by means of a rolling bearing.
  • the part axles can be designed as massive forgings.
  • the bearing pedestals are attached to the axle body after forging the part axles. Basically, a division of the bearing base in two, the axis each on a circumference of 180 degrees surrounded parts is sufficient. If the bearing base made in one piece, it is necessary to subsequently attach one of the two flanges of each sub-axis, for example, by shrinking, but this is unfavorable in terms of production technology.
  • each bearing pedestal is preferably connected in a form-locking manner to one of the two sub-axles.
  • the positive connection can be effected, for example, by a collar surrounding the axle body of each partial axle, which engages in a corresponding circumferential groove in the bearing socket.
  • the two sub-axes are additionally connected to the bearing blocks and on the inner flanges via journals.
  • the journal on the two inner flanges engage in a passage in the web plate whose diameter corresponds to the outer diameter of the journal.
  • the length of the two pins is smaller than the thickness of the web plate in the region of the passage.
  • a rope groove (3) for a hoisting rope (4) is arranged on the cylinder jacket (1) of the traction sheave shaft carrier (2) .
  • the cylinder jacket (1) is supported on side bearings (5a, 5b), which are equipped with closable manhole holes (6) on rolling bearings (7), which in turn on stationary bearing pedestals (8a, 8b) are mounted.
  • a circumferential web plate (9) On the inner circumference of the cylinder jacket (1) is centrally mounted a circumferential web plate (9) on which the rotor (12) of the internal motor is mounted.
  • the rotor (12) is formed by a Pollustblech (10) and arranged thereon magnetic poles (11). Opposite the rotor (12) is separated by an air gap (13), the stator (14), which is connected via a multi-angled, circumferential web plate (15) releasably connected to the axis of two axes (16a, 16b).
  • the circumferential web plates (9,15) divide the cavity within the cylinder jacket (1) and between the side shields (5a, 5b) in two areas, which are interconnected by the air gap (13).
  • the two sub-axes (16a, 16b) are designed as forgings. At each partial axis (16a, 16b) an outer flange (18a, 18b) and an inner flange (19a, 19b) are provided on the front side. Between the two inner flanges (19a, 19b), the circumferential web plate (15) is clamped when the two sub-axes (16a, 16b) are screwed together.
  • the two outer flanges (18a, 18b) are bolted to bearing blocks (20a, 20b), which transmit the forces and torques to the foundation frame (21a, 21b).
  • the foundation frames (21a, 21b) are supported on the foundation (22).
  • the bearing base (8a, 8b) are positively connected to the sub-axes (16a, 16b).
  • the cooling air for cooling the internal motor enters the cavity (17) from the outside through cooling air passage openings (25a) in the bearing base (8a) and is forcibly guided through the air gap (13) between the rotor (12) and stator (14) and leaves the cavity (17) through the arranged on the opposite side cooling air passage openings (25b) in the bearing base (8b).
  • the cooling air is supplied via channels, not shown, and air covers.
  • the removal of the heated air to a likewise not shown air cooling system also takes place via channels and air ducts, not shown.
