Definitions
- the invention relates to a drive unit for elevators consisting of a motor, a brake and a between End shields arranged traction sheave, the motor is arranged on a bearing plate and the bearing plates are carried by a machine frame.
- a disadvantage of the known device is that the brake is arranged on the outside.
- the brake parts can easily become dirty or mechanically damaged become.
- the invention seeks to remedy this.
- the invention as characterized in claim 1 solves the problem to avoid the disadvantages of the known device and to create an elevator drive with brake that is in everyone Case works reliably.
- the advantages achieved by the invention are in essential to see that a drive unit with short shaft and thus a small overall length of the Drive unit is realizable. It is also advantageous that the brake release cylinder and supply lines from the Brake drum are arranged separately. If the Brake release cylinder can be operated hydraulically, in In the event of a leak or line break the active ones Do not oil the braking surfaces. The braking readiness remains still guaranteed.
- Fig. 1 shows the fully assembled drive unit, in essentially consisting of an engine 1, a Bearing plate serving motor stand 2, one as a bearing plate serving bearing block 5, a traction sheave 15 and one Machine frame 7 with counter roller attachment 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 the traction sheave 15 sits on a free end load-bearing shaft, not shown, on the bearing block 5 and is mounted on the motor stand 2.
- the by a breakout in a cable protection casing 3 is visible traction sheave 15 by means of the shaft on the motor stand 2 and on the bearing block 5 stored.
- a brake 6 is in the inner area of the Motor stand 2 arranged and with the casing 3rd covered.
- the Brake 6 also in the inner area of the bearing block 5 be arranged.
- the motor stand 2 and the bearing block 5 are on Machine frame 7 arranged, which at each corner has an adjustable support element 8.
- the Counter roller attachment 9 is at the bottom of the Machine frame 7 arranged. All electrical connections the drive unit are located in a terminal box 10th
- FIGS. 2a to 2d The design of the brake 6 and the engine stand 2 is explained in more detail in FIGS. 2a to 2d, with FIG. 2a is an assembled one in FIGS. 2b and 2c exploded view of the assembly can be seen.
- the motor stand 2 consists of an approximately rectangular Plate 2.1, which together with two vertical walls 2.3 and a horizontal wall 2.4 and 2.5 den flat, box-shaped motor stand 2 forms.
- the plate 2.1 has a bearing seat 2.2 in the middle for the motor-side bearings of the shaft and some openings 2.6 for the passage of the cooling air for cooling the engine 1.
- the holes 2.7 in the lower area of the motor stand 2 are provided for receiving brake bolts 11.
- the side walls 2.3 have in the upper area Breakthroughs 2.8 for coil springs 16 and breakthroughs 2.9 for Drawbars 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 to reinforce the structure and allow the absorption of the forces which arise when opening the Brake 6 through the hydraulic cylinders 23 onto the ribs 2.10 act.
- a U-shaped wall 2.12 on the inside of the wall 2.4 forms a rigid together with reinforcing ribs 2.13 Structure that absorbs the spring forces from the holes 2.14 inserted threaded rods 19 takes over.
- Lifting eyes 2.15 serve to hang the motor stand 2 or the assembled drive unit according to FIG. 1.
- the brake 6 consists of two on the brake bolts 11 mounted brake levers 12, which on the bolt 13th stored brake shoes 14 on the drum 15.1 Traction sheave 15 act.
- the braking force is generated by springs 16 generated that press the brake lever 12 at one end and at the other end via pressure plates 17 and nuts 18 Transfer force to the threaded rods 19.
- the Threaded rods 19 are through the holes 12.1 in the Brake levers 12 and holes 2.14 in the engine stand 2 inserted and by means of crown nuts 21 with split pin fixed. The spring force can thus be applied via the joint bearing 22 on the inside of the wall 2.12 of the motor stand 2 be initiated.
- Holes 2.14 and 12.1 are correspondingly larger than that Threaded rod 19 and thus allow one to ventilate the Brake 6 required rotation of the brake lever 12 around the axis of the bolts 11.
- the spherical bearings 22 ensure a vertical introduction of the forces on the wall 2.12 of the Motor stand 2.
- An angle 20 slidably attached to the brake lever 12 limits the freedom of movement of the brake shoe 14 below and prevents the contact of the brake 6 open 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 Pistons 23.1 outwards.
- About the tie rod 24 Transfer movement of the piston 23.1 to the brake lever 12.
- the movement of the piston 23.1 is through the cylinder cover 23.2 limited.
- the pull rod 24 has at both ends 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 with the shaft circlip 27 fixed on the tie rod 24.
- the axial spherical bearings 28 and the correspondingly large holes 12.2 in the Brake levers 12 ensure that the pull rod 24 in each Operating condition is only axially loaded.
- the shims 29 allow the adjustment of the release path of the brake levers 12th
