Definitions

  • the invention relates to a drive unit for elevators consisting of a motor arranged in a housing, which drives a traction sheave by means of a drive shaft, the traction sheave using a braking device is fixable.
  • DD 44 278 is an electrical Elevator motor with connected traction sheave and Brake drum became known. Traction sheave and Brake drum are outside of the motor housing and the drive-side bearing at a free shaft end arranged on the fly. The traction sheave and the brake drum can be made in one piece. As The two-shoe brake consists of one Actuator, from brake brackets and brake shoes, wherein the actuator from the outside of the motor housing is attached. To accommodate the high drive pulley side Loads is a bearing plate and a bearing for high Loads provided.
  • a disadvantage of the known device is that due to the flying arrangement of the traction sheave and the brake drum is an expensive end shield with bearings for high Loads is necessary. Another disadvantage is that lateral arrangement of the brake bracket and the brake shoes what increases the diameter of the drive unit.
  • the drive unit consists of a motor arranged in a housing, which by means of a drive shaft drives a traction sheave, the Traction sheave lockable by a braking device is.
  • 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 a drive unit in a flat design.
  • the advantages achieved by the invention are in essential to see that the drive unit builds slim at right angles to the drive shaft and that thanks the slim design the drive unit in one Elevator shaft, for example, in the area between the Track area of the cabin and the shaft wall can be installed is.
  • Another advantage is the common Support of the traction sheave and the drive shaft. On there is no free shaft end without support that Traction sheave is supported directly on the end shield. Bending forces on the drive shaft can thereby be avoided become.
  • 1 to 3 with 1 is a drive unit referred to, which consists essentially of a housing 2, a Drive shaft 3, a stator connected to the housing 2 4 and a rotor 5 connected to the drive shaft 3 consists. Stator 4 and rotor 5 form the drive motor.
  • the Drive shaft 3 is at one end of a first bearing 6 worn, which on a first End shield 2.1 is arranged, which is part of the Housing 2 is.
  • a traction sheave 7 is arranged over which not shown ropes for carrying and moving one Elevator car or a counterweight are performed.
  • the Traction sheave 7 or the other, üs free end of the drive shaft 3 are from a second Bearing 8, which is arranged on a boom 9, carried.
  • the boom 9 is part of a second Bearing plate 2.2, which is part of the housing 2.
  • the Traction sheave 7 has a serving as a brake drum 11 Process on.
  • the between traction sheave 7 and housing 2 arranged brake drum 11 forms together with the first Brake levers 12, second brake levers 13, first Electromagnet 14, second electromagnet 15, first Compression springs 16 and second compression springs, not shown the braking device of the drive unit.
  • At the top of the second End shield 2.2 is a first lever joint 17 and at the bottom second end shield 2.2 is a second lever joint 18 arranged.
  • the first brake lever 12 is on the first Lever joint 17 and the second brake lever 13 is on the second Lever joint 18 rotatably arranged.
  • the power of the first Compression spring 16 is opened by means of the first brake lever 12 transfer the brake drum 11, a first on one first brake shoe 19 arranged brake pad 20 the necessary friction force generated on the brake drum 11.
  • the Force of the second compression spring is by means of the second Transfer brake lever 13 to the brake drum 11, wherein a second arranged on a second brake shoe 21 Brake pad 22 the necessary friction on the brake drum 11 generated.
  • the Electromagnets 14, 15 activated, the forces of Overcome compression springs and the brake shoes 19, 21 with the Lift the brake pads 20, 22 off the brake drum 11.
  • the electromagnets 14, 15 can also hydraulic lifting cylinders can be provided.
  • a rope safety device 23 arranged on the drive pulley side prevents the cables from jumping off the traction sheave 7.
  • a shaft end 24 is provided, the for example, the revolutions of the drive shaft 3 detecting sensor, not shown drives.
  • a junction box 25 for the top of the housing 2 the electrical supply to the drive unit 1 intended.
  • the width B of the Drive unit is only determined by the size of the stator 4 and rotor 5 formed motor determined, lateral There are no structures that increase the width B.
  • the Diameter D of the traction sheave 7 is smaller or the same as large as the width B of the drive unit.
  • the embodiment shown relates to a gearless drive unit.
  • the inventive Traction sheave with the braking device and its storage can also be used, for example, in drive units with gears be used.
  • a disc brake may be provided, wherein the extension of the traction sheave 7 is disc-shaped and the brake shoes 19, 21 at the top and / or at the bottom Housing 2 are arranged on both sides of the brake disc.
