Definitions
- the invention relates to a gearless drive machine of an elevator consisting of a motor, a traction sheave carried by a motor shaft, over which ropes for carrying and moving an elevator car and a counterweight are guided, a brake device arranged on a bearing block for stopping the motor and an actuating device for the Emergency operation by means of which the motor can be operated manually.
- a drive unit for an elevator has become known from the document EP 0 706 968 A2.
- the drive unit has a continuous shaft that both the
- a gear with a traction sheave for the elevator cables is arranged at one end of the shaft.
- a handwheel is attached to the motor-side free end of the shaft for emergency actuation of the drive unit.
- Levers carrying brake shoes are articulated on a base plate. The brake shoes are pressed against the outer circumference of a brake body by means of a cylinder.
- a disadvantage of the known device is that the handwheel is arranged close to the motor. When the handwheel is actuated, fingers can easily be gripped and pinched by the rotating handwheel. In the event of an emergency actuation, the brake must be released and the handwheel operated at the same time. Releasing the brake is difficult because of the brake assembly on one side and the handwheel on the other side of the motor.
- gear with a handwheel is usually used for this, the gear being connected to the main shaft by means of a coupling device.
- Such devices are expensive, cumbersome and not entirely safe to use.
- the invention seeks to remedy this.
- the invention as characterized in claim 1, solves the problem of avoiding the disadvantages of the known device and of creating a manual drive with a handwheel by means of which an emergency actuation of the elevator is problem-free and safe.
- the advantages achieved by the invention are essentially to be seen in the fact that the manual drive can be installed easily and without tools.
- the manual drive can be attached to the drive machine if required.
- a coupling, as is necessary with a permanently mounted manual drive, is not required.
- the safety of the persons performing the emergency operation is guaranteed in any case because the electric drive is automatically switched off when the manual drive is attached.
- a manual drive is sufficient, which can be used in each case for the elevator to be actuated in an emergency.
- Fig. 3 details of the manual drive
- Fig. 4 is an end cap in connection with the manual drive of a bearing block.
- a gearless drive machine 1 with a motor 2 consisting of a stator and rotor which drives a traction sheave 3.
- Ropes (not shown) are guided over the traction sheave 3 and a deflection roller 4, which carry and drive an elevator car (not shown) and a counterweight (not shown).
- Traction sheave 3 is supported by a motor shaft 2.1, which is supported on one end on a bearing plate (not shown) and on the other end on a bearing block 5.
- Motor 2 bearing plate, bearing block 5 and deflection roller 4 are carried by a machine console 6.
- the drive machine comprises a braking device 7 with a first brake lever 8 and a second brake lever 9, on each of which a brake shoe is arranged.
- the brake levers 8, 9 are articulated on the bearing block 5 at the bottom and guided on a rod 10 at the top.
- the rod 10 is arranged centrally on a holder 11 connected to the bearing block 5.
- a compression spring 12, 13 is provided for each brake lever 8, 9 to actuate the brake shoes.
- a magnet is provided for each brake lever 8,9, which counteracts the ⁇ ⁇ D DO HH

- Fig. 2 shows the manual drive 18 with handwheel 18.1 from the drive machine side.
- An elongated hole 28 is arranged at the end of a hollow axis 27 of the handwheel 18.1.
- the hollow axis 27 is an extension 29 a
- Screw axis 30 can be plugged on, a bolt 31 of the extension 29 fitting into the slot 28, as a result of which the rotary movement of the handwheel 18.1 is transmitted to the screw shaft 30.
- a pin 33 arranged on a housing 32 serves as a torque support.
- a hub 34 with a groove 35 can be pushed onto the motor shaft 2.1.
- Handles 36 facilitate the attachment of the manual drive 18 to the drive machine 1 and the removal of the manual drive 18 from the drive machine 1.
- the worm shaft 30 drives a worm wheel 37, into which an extension 38 of the hub 34 is inserted.
- the extension 38 of the hub 34 and the worm shaft 30 are mounted on both sides in the housing 32.
- a first casing 39 with the handles 36 and a second casing 40 close off the housing 32.
- Fig. 4 shows an interior view of the end cover 19, which closes the bearing block 5.
- the end cover 19 serves as a contactor for the shaft end of the motor shaft 2.1 and at the same time permits simple assembly of the manual drive 19.
- the opening 20 of the end cover 19, through which the hub 34 extends, can be closed by means of a sliding cover 41 and a closing element 42.
- the sliding cover 41 is guided by means of guide rails 43.
- a sensor 44 is provided on the end cover 19, for example a microswitch, which can be actuated by means of a curve 45 arranged on the sliding cover 41.
- the sensor 44 prevents electrical operation of the drive machine 1.
- a hole 46 in the end cover 19 receives the pin 33 when the manual drive 1 is in place. Pin 33 and hole 46 form the torque support of the manual drive 18th
