Definitions

  • the invention relates to a drive unit for an elevator consisting of a motor, serving as a bearing plate motor stand, wherein the motor is arranged on the motor stand, serving as a bearing block bearing block, a bearing frame bearing machine frame, arranged between the bearing plates traction sheave and one on the traction sheave acting brake.
  • a reciprocating motor fed with alternating voltage consists essentially of a stator and of a rotor with a rotor hub which can be pushed onto the main shaft.
  • a second clamping set creates a firm connection between the main shaft and the rotor hub.
  • a disadvantage of the known devices is that the brake is arranged outboard.
  • the brake parts can easily become dirty or mechanically damaged.
  • the invention aims to remedy this situation.
  • the invention as characterized in claim 1 solves the problem to avoid the disadvantages of the known device and to provide an elevator drive with brake, which operates reliably in each case.
  • 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 supply lines are arranged separately from the brake drum. If the brake release cylinder can be actuated hydraulically, the active braking surfaces can not become oily in the event of leakage or line breakage. Brake readiness remains guaranteed.
  • Fig. 1 shows the ready assembled drive unit, consisting essentially of a motor 1, serving as a bearing plate motor stand 2, serving as a bearing plate bearing block 5, a traction sheave 15 and a machine frame 7 with Gegenrollenanbau 9.
  • the stator of the electric motor 1 is by means of a flange with the Motor stand 2 screwed.
  • the rotor of the electric motor 1 is seated on a free end of a shaft carrying the traction sheave 15, not shown, which is mounted on the bearing block 5 and the motor stator 2.
  • the free end of the shaft projects beyond the motor stand 2.
  • the traction sheave 15, which is visible through an outbreak in a cable protection shuttering 3, is mounted on the motor stand 2 and on the bearing block 5 by means of the shaft.
  • a brake 6 is arranged in the inner region of the motor stator 2 and covered with the shuttering 3. Depending on the structure of the drive unit, the brake 6 can also be arranged in the inner region of the bearing block 5.
  • the motor stand 2 and the bearing block 5 are arranged on the machine frame 7, which has an adjustable support element 8 at its corners.
  • the Schmidtrollenanbau 9 is arranged on the underside of the machine frame 7. All electrical connections of the drive unit are located in a terminal box 10th
  • Fig. 2a to 2d The structural design of the brake 6 and the motor stator 2 is in the Fig. 2a to 2d explained in more detail, wherein in Fig. 2a an assembled and in Fig. 2b and 2c an exploded view of the assembly can be seen.
  • the motor stand 2 consists of an approximately rectangular Plate 2.1, which forms the flat, box-shaped motor stand 2 together with two vertical walls 2.3 and one horizontal wall 2.4 and 2.5.
  • the plate 2.1 has in the middle a bearing seat 2.2 for the motor-side bearing of the shaft and some openings 2.6 for the passage of the cooling air for cooling the motor 1.
  • the holes 2.7 in the lower part of the motor stand 2 are provided for receiving brake pin 11.
  • the lateral walls 2.3 have in the upper part openings 2.8 for coil springs 16 and openings 2.9 for pull rods 24 of the hydraulic cylinder 23.
  • ribs 2.10 on the outside of the wall 2.3 together with the inside arranged ribs 2.11 serve the structural reinforcement and allow the absorption of forces, which when opening the brake 6 act through the hydraulic cylinder 23 on the ribs 2.10.
  • a U-shaped wall 2.12 on the inside of the wall 2.4 forms together with reinforcing ribs 2.13 a rigid structure, which takes over the spring forces of the threaded rods 19 inserted through holes 2.14.
  • Lifting eyes 2.15 are used to suspend the motor stand 2 or the assembled drive unit Fig. 1 ,
  • the brake 6 consists of two brake levers 12 which are mounted on the brake pin 11 and which act on the drum 15.1 of the traction sheave 15 via the brake shoes 14 mounted on bolts 13.
  • the braking force is generated by springs 16 which press at one end on the brake lever 12 and at the other end via pressure plates 17 and nuts 18 transmit the force to the threaded rods 19.
  • the threaded rods 19 are through the holes 12.1 in the brake levers 12 and the holes 2.14 in the motor stand. 2 put through and fixed by means of crown nuts 21 with split pin.
  • the spring force can be introduced via the pivot bearing 22 on the inside of the wall 2.12 of the motor stator 2.
  • the holes 2.14 and 12.1 are correspondingly larger than the threaded rod 19 and thus allow a required for releasing the brake 6 rotational movement of the brake lever 12 about the axis of the bolt 11.
  • the spherical bearings 22 provide a vertical introduction of the forces on the wall of the motor stand 2.12. 2 ,
  • a slidably mounted on the brake lever 12 angle 20 limits the freedom of movement of the brake shoe 14 down and prevents the open brake 6, the contact of the brake shoes 14 with the brake drum 15.1 of the traction sheave 15th
  • Fig. 2d shows details of the spring force of the springs 16 counteracting hydraulic cylinder 23.
  • the hydraulic cylinder 23 supplied pressure medium causes the displacement of the hollow piston 23.1 after Outside.
  • the pull rod 24 has at both ends depending on a groove 24.1, in each of which two half rings 25 are used.
  • a retaining ring 26 holds the half-rings 25 in position and is itself fixed with the shaft-locking ring 27 on the pull rod 24.
  • the axial spherical plain bearings 28 and the correspondingly large-sized holes 12.2 in the Brake levers 12 ensure that the pull rod 24 is loaded only axially in each operating condition.
  • the shims 29 allow the adjustment of the Lsymmetricweges the brake lever 12th
