Elevator traction machine and method for improving comprehensive performance thereof

Abstract

The invention discloses an elevator traction machine and a method for improving the comprehensive performance thereof. The method for improving the comprehensive performance of the elevator traction machine includes forming a connecting seat by the aid of a bending forming process and forming arc-shaped mounting grooves for mounting a brake; constraining a stator coil by the aid of grooves and positioning pins when the stator coil rotates; fastening magnetic steel by the aid of bosses and a magnetic steel pressing component; connecting a gear ring onto a traction sheave by the aid of a seam and lugs. The elevator traction machine which is constructed by the aid of the method comprises a base (1). The brake (3) is connected to the top of the base (1) by the connecting seat (2); the stator coil (4) is arranged in the base (1), and a rotor yoke (5) is arranged between the stator coil (4) and the base (1); the magnetic steel (6) is arranged in the rotor yoke (5), and the gear ring (8) is connected to the outside of the rotor yoke (5) by the traction sheave (7). The elevator traction machine and the method have the advantages that the brake can be conveniently fixed, the stator coil can be prevented from rotating, the magnetic steel is convenient to detach and replace, the magnetic steel fastening stability can be improved, and the elevator traction machine is high in integral strength and low in machining cost.

Description

technical field [0001] The invention relates to a method for improving the performance of a traction machine and the traction machine, in particular to a method for improving the comprehensive performance of the elevator traction machine and the elevator traction machine. Background technique [0002] In the existing elevator traction machine, the brake is generally connected to the connecting plate with bolts first, and then the connecting plate is fixed on the frame by bolts, so as to realize the installation of the brake on the frame. However, in this case, the strength of the connecting plate is low, and since the brakes used in general elevator traction machines are all cylindrical, it is difficult to fix the brakes. [0003] In the existing elevator traction machine, the stator coil is generally connected to the machine base through tension pins. However, such connection stability is not ideal, the stator coil is easy to rotate relative to the frame, and the connectio...

Problems solved by technology

However, due to the large thickness of the traction sheave and the small diameter of the connecting surface between the rotor yoke and the traction sheave, the position of the bolts used for connecting the traction sheave and the rotor yoke is far from the outer ring of the traction sheave, and the ring gear needs to Set several larger lugs to match the position of the bolts, the material used for the ring gear increases, and the processing cost is higher

[0006] Therefore, the existing elevator traction machine has the problems that the brake is difficult to fix, the stator coil is easy to rotate, the magnetic steel is difficult to disassemble, the fastening stability of the magnetic steel is not ideal, and the processing cost is high.
