Elevator Traction Machine With Gear

At present, geared traction machines are generally used in various freight Elevators Traction Machine With Gear and sundry elevators. In order to reduce the noise and improve the stability of the traction machine during operation, the turbine pair is generally used as the reduction transmission device. In the past ten years, geared traction machines have also developed greatly, such as planetary gear traction machines and helical gear traction machines, which not only improved the low efficiency of the turbine pair transmission, but also increased the running speed of geared traction machine elevators. , The elevator with speed v≥2m/s has begun to use these two types of geared traction machines.

The worm gear traction machine is mainly composed of a traction motor, worm, worm gear, Elevator Traction Machine With Gear brake, traction sheave, machine base, etc. Its appearance . The traction motor of the geared traction machine is connected to the worm through a coupling, and the worm wheel and the traction sheave are installed on the same shaft. Due to the meshing relationship between the worm and the worm wheel, the traction motor can drive the worm wheel and the sheave to run forward and reverse through the worm. The elevator car and the counterweight device are respectively connected to the two ends of the traction wire rope, and the traction wire rope is wound on the traction sheave. When the traction sheave rotates, the car and the counterweight device are driven to run up and down through the friction force (also called traction force) between the traction rope and the traction sheave. In order to improve the traction force of the elevator, traction rope grooves as shown in traction sheave, and the traction wire ropes are respectively located in the rope grooves.

The traction system of the elevator using the single winding 2:1 rope winding method . traction machine is One of the main components of the elevator. The main parameters such as the load and running speed of the elevator depend on the motor power and speed of the traction machine, the modulus and reduction ratio of the worm and worm gear, the diameter of the traction sheave, the number of rope grooves, and the traction ratio (traction mode), etc.

In recent years, with the development of science and technology and the introduction of technology, in addition to the worm gear pair with Archimedes tooth shape, K-shaped tooth shape worm gear pair, involute tooth shape worm gear pair, and spherical tooth shape worm gear pair have appeared. A new type of traction machine assembled with new tooth-shaped worm gear pairs such as worm gear pairs and double-enveloping multi-tooth meshing worm gear pairs. Because these new toothed worm gears have higher transmission efficiency than the Archimedes toothed worm gears, so the output torque is larger under the same modulus. In the case of the same running speed and rated load, the power of the traction motor and the model ofthe traction machine can be reduced, which not only saves energy but also saves raw material consumption. In this regard, some parameters in Table 3-1 need to be corrected.For an elevator with a geared traction machine, the relationship between its running speed and the reduction ratio of the traction machine, the diameter of the traction sheave, thetraction ratio, and the speed of the traction motor can be expressed by the following formula:

v=πDn/60iyij

V——-elevator running speed, m/s;

• D——-diameter of traction sheave, m;
  smell
• iy—–traction ratio (magnification);
  ij——Reduction ratio;
  n——-Traction motor speed, r/min.
