Definitions

  • the invention relates to a machine frame-less drive unit for a lift consisting of at least one motor, at least one brake and a traction sheave arranged between bearing plates, wherein the motor is arranged on a bearing plate.
  • a drive unit consisting essentially of an electric motor, a motor stand, a bearing block, a traction sheave and a machine frame with Gegenrollenanbau known.
  • the stator of the electric motor is screwed by means of a flange to the motor stand.
  • the rotor of the electric motor is seated on a free end of a shaft carrying the traction sheave, which is mounted on the bearing block and the motor stator.
  • the traction sheave is mounted by means of the shaft on the motor stand and on the bearing block.
  • a brake is arranged in the inner region of the motor stand and covered with a shuttering.
  • a disadvantage of the known device is that the brake is arranged on the inside. For maintenance, the brake parts are difficult to access.
  • Another disadvantage is that no Evakuier horr is provided.
  • the invention aims to remedy this situation.
  • the invention as characterized in claim 1 solves the problem of avoiding the disadvantages of the known device and To provide an elevator drive with brake, which works reliably in any case and is simple.
  • the advantages achieved by the invention are to be seen essentially in the fact that a drive unit with a short shaft and thus a small overall length of the drive unit can be realized. It is also advantageous that the brake release cylinder and leads are arranged separately from the brake disc. In the case of leakage or line break, the braking surfaces can not oil. Brake readiness remains guaranteed. It is also advantageous that there is more freedom for the cable guide between the traction sheave and the counter-roller with the machine frame-less design of the drive unit. As a result, larger wire rope distances are feasible. For example, the drive unit designed for large elevator cars and for large delivery heights and high speeds has a height of more than two meters and a total weight of more than ten tons, whereby weight and costs can be saved with the frame-less design. It is also advantageous that an evacuation engages over a sprocket and a pinion with the brake disc.
  • Fig. 1 shows the ready assembled drive unit 1, consisting essentially of a motor 2A, serving as a bearing plate motor stand 3, serving as a bearing plate bearing block 4, a traction sheave 5 and a Gegenrollenanbau 6.
  • the stator 2.1 of the electric motor 2A is arranged on the motor stator 3.
  • the rotor 2.2 of the electric motor 2A is seated on a free end of a shaft 15 carrying the traction sheave 15, which is mounted on the bearing block 4 and on the motor stator 3.
  • the free end of the shaft projects beyond the motor stand 3.
  • the traction sheave 5 is mounted on the motor stand 3 and on the bearing block 4 by means of the shaft.
  • Per side of a brake 7 is arranged on the bearing block 4.
  • Webs 8.9 connect the motor stand 3 with the bearing block 4, wherein, for example, an upper web 8 and a side web 9 are provided on each side.
  • Motor stand 3, bracket 4 and the webs 8.9 form a stable framework without a motor stand 3 and bearing block 4 supporting machine frame is necessary.
  • Motor stand 3 and bearing block 4 are supported by means of supporting elements 10 on a boom 3.1 or on a boom 4.1 without a frame on each base 11 or carrier.
  • the Schmidtenanbau 6 consisting of side plates 12 and counter-roller 13 is right on Motor stand 3 and arranged on the bearing block 4.
  • a hydraulic unit 14 serves to supply the actuator of the brake 7. The actuator can also be operated electrically.
  • Supporting cables 25 form the cable strand, which are guided on the one hand by the traction sheave 5 via the counter-roller 13 and on the other hand by the traction sheave 5 directly into the elevator shaft.
  • the cable string spacing is adjustable by means of the Schmidtrollenanbaus 6, wherein the side plates 12 are screwed to holes 12.1 with the motor stand 3 and with the bearing block 4.
  • Fig. 2 shows the motor stand 3 with traction sheave 5, the lateral webs 9 and the upper web 8.
  • the bearing block 4 is in the Fig. 3 shown.
  • a shaft 15 carrying the traction sheave 15 is mounted at one end on the motor stand 3 and at the other end on the bearing block 4.
  • the bearing block side bearing is designated 16.
  • a brake disc 17 is arranged with ring gear 18 through which the traction sheave 5 is driven in the evacuation operation.
  • Fig. 3 shows an interior view of the bearing block 4 with bearing housing 19 for receiving the bearing 16.
  • eyelets 20 are visible on which the brake 7 is mounted.
  • the support surface for the upper web 8 is 21 and the Aufläge vom for the lateral webs 9 are designated 22, wherein the webs are 8.9 screwed to the bearing block 4 and the motor stand 3, for example.
  • the Evakuierantrieb consists of a motor 23 with pinion 24, wherein in evacuation operation, the pinion 24 engages the ring gear 18 and the traction sheave 5 is set in motion.
  • Fig. 4 shows the upper web 8, which is box-shaped and the support surface 8.1 fits on the support surface 21.
  • Fig. 5 shows the lateral web 9, which is wedge-shaped and the support surface 9.1 fits on the support surface 22.
  • Fig. 6 and Fig. 7 show the bearing block 4 on each side arranged brake 7 of the drive unit 1, wherein a brake caliper 30 to the lugs 20 penetrating axes 31 is floatingly mounted.
  • the caliper 30 can move at most to the adjustable by means of adjusting screws 32 distance d, wherein each axle 31, a spring 33 is provided which acts on the caliper 30 in the direction of traction sheave 5.
  • the axles 31 are fastened to a supporting bracket 34 connected to the bearing block 4.
  • the caliper 30 carries the drive pulley side, inner brake shoe 40 and serves as a support for spacer tubes 35 and threaded rods 36 which hold a support plate 37 for a hydraulic actuator 38, for example.
  • Compression springs 39 are supported at one end on the carrier plate 37 and at the other end against a pressure plate 41, which transmits the spring force of the compression springs 39 to the outer brake shoe 43 by means of bolts 42 guided by the brake caliper 30.
  • the activated actuator 38 acts by means of a pull rod 44 on the pressure plate 41 and lifts the spring force of coaxial with the pull rod 44 arranged compression springs 39 on the outer brake shoe 43.
  • the caliper 30 moves due to the spring force of the spring 33 in the direction of traction sheave 5, wherein the inner brake shoe 40 moves away from the brake disk 17.
  • a sensor 45 is provided for monitoring the braking state.
  • Fig. 8 shows the fully assembled drive unit 1 with two motors, consisting essentially of a motor 2A and a motor 2B, serving as a bearing plate motor stand 3, serving as a bearing plate bearing block 4, a traction sheave 5 and a Gegenrollenanbau 6.
  • the drive pulley 5 supporting, mounted on the bearing plates 3.4 shaft 15 has two free ends, wherein at one free end of the rotor of a motor 2A and at the other free end of the rotor of the other motor 2B is arranged.
  • Webs 8.9 connect the motor stand 3 with the bearing block 4, wherein, for example, an upper web 8 and a side web 9 are provided on each side.
  • Motor stand 3, bracket 4 and the webs 8.9 form a stable framework without a motor stand 3 and bearing block 4 supporting machine frame is necessary.
