A casing-less switch reluctance traction machine

Abstract

The invention discloses a switch reluctance traction machine without a casing, which mainly includes an end cover A, a rotor shaft, a rotor iron core, a stator iron core, an end cover B, and a traction wheel. The middle part of the rotor shaft is synchronously connected to the rotor Iron core, one side of the rotor core is provided with an end cap A which is axially connected to the rotor shaft through a deep groove ball bearing; the other side of the rotor core is provided with an end cover A which is axially connected to the rotor shaft through a self-aligning roller bearing Cover B, a traction sheave is arranged outside the end cover B; the stator core is fixed between the end cover A and the end cover B, and the stator core seals the rotor core inside, and the stator core and the rotor There are gaps between the iron cores. The utility model has the advantages of simple structure, convenient installation and use, low cost and no noise pollution.

Description

technical field [0001] The invention belongs to the technical field of power equipment, and in particular relates to a casing-less switched reluctance traction machine used for elevators and the like. Background technique [0002] The traction machine is mainly divided into a gear traction machine and a gearless traction machine. [0003] Geared traction machine: The power of the dragging device is transmitted to the traction wheel through the intermediate reducer. The reduction box in it usually adopts worm gear transmission (helical gear transmission is also used). This traction machine uses There are AC and DC motors, and they are generally used in low-speed elevators and high-speed elevators. The drag ratio is typically 35:2. Generally used for low and medium speed elevators below 0.4m / s. [0004] Gearless traction machine: The power of the traction device is directly transmitted to the traction wheel without an intermediate reducer. In the past, most of these tracti...
