Simple an-skid device with unidirectional binding tape at rotor end part

Abstract

The invention relates to a simple an-skid device with a unidirectional binding tape at a rotor end part, which comprises alkali-free glass wool cloth (2), two polyester ropes (3), a connecting member (5) and the unidirectional tape (4), wherein the alkali-free glass wool cloth (2) is fixed at the end part of a rotor coil (1), the two polyester ropes (3) are arranged on the alkali-free glass wool cloth (2) in parallel, two ends of the alkali-free glass wool cloth (2) bypass through the polyester ropes (3) and are connected together through the connecting member (5), the unidirectional tape (4) is arranged above the alkali-free glass wool cloth (2), and the thickness of the alkali-free glass wool cloth (2) is less than the diameter of each polyester rope (3). The simple an-skid device has the advantages that the structure is simple, the alkali-free glass wool cloth and the polyester ropes are bonded in the circumference direction by adopting a matching mode to form a protruding edge, and thus the axial jumping is prevented when the unidirectional tape is lapped, the function of limiting a binding region of the unidirectional tape is achieved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a simple anti-skid device for binding no weft tape at the end of a rotor. Background technique [0002] Wound motor is a kind of three-phase asynchronous motor, including stator and rotor. When the wound motor is manufactured, the rotor needs to be bound with a latitude-free tape, and it needs to be carried out with a cable when binding the latitude-free tape. [0003] Before binding the latitude-free belt, the rotor needs to be fixed first. Usually, the rotating shaft of the rotor is clamped by a lathe. However, since the cable protrudes from the end face of the rotating shaft, the thimble of the lathe cannot withstand the inner hole of the rotating shaft due to the influence of the cable, and cannot align the rotor in the axial direction. Carry out positioning, bring inconvenience to the binding operation of no weft tape. [0004] Similarly, after the rotor coil of the doubly-...
