Novel separated micro-electric slip ring

Abstract

The invention discloses a novel separated micro-electric slip ring, and relates to the technical field of electrical devices. The novel separated micro-electric slip ring comprises a rotor, one end of the rotor is provided with a wire connection terminal b, the outer side wall of the rotor is fixedly sleeved with a slip ring, the outer side wall of the slip ring is slidably sleeved with an electric brush, and the rotor is provided with a hemispherical groove guide rail corresponding to the electric brush. The electric slip ring is simple in structure, low in cost, convenient to maintain, short in machining period, detachable, capable of being assembled, suitable for occasions of different types, capable of being installed in positions such as through holes or gaps or thin walls and small in use limitation. The electric slip ring is supported by multiple ends, so the electric slip ring is prevented from being damaged due to ignition caused by radial shaking of the slip ring due to centrifugal force and radial unbalanced force in the running process of the motor. In a low-speed state, the electric slip ring can not be provided with a bearing and a shell, the fixing position is flexible and convenient, and a user can select according to conditions.

Description

technical field [0001] The invention relates to the technical field of electrical devices, in particular to a novel separated microelectric slip ring. Background technique [0002] Electric slip rings are slip rings used to conduct electricity. They are the most widely used in all slip ring series. When the continuous rotation is limited, the power supply and signal power are transmitted. [0003] In the prior art, there are many electric slip rings already in use, such as: [0004] 1. The Chinese patent application number is CN201821226109.7, which discloses a conductive slip ring structure for quickly adjusting the pressure of the slip ring brush, including a conductive slip ring bracket shell, a conductive ring and a conductive brush. The conductive ring is positioned and fixed on the rotating shaft of the conductive ring Above, the rotating shaft of the conductive ring is rotated and fixed on the shell of the conductive slip ring bracket through the bearings at both en...

AI Technical Summary

Problems solved by technology

[0005] The disadvantages are: as the number of channels increases, the length of the slip ring will be longer, and the fixing method is relatively simple. It needs a support column or a high platform, and cannot be fixed in a narrow space.

[0007] The disadvantage is: the slip ring of the airborne structure, the slip ring device is installed at the tail end of the motor rotor shaft, the slip ring is actually a single-end supported cantilever beam structure, so during the operation of the motor, due to centrifugal force and radial unbalanced moment The effect of the slip ring will inevitably produce radial vibration, especially when starting and speed regulation operation, the phenomenon is more obvious

[0009] The disadvantage is: the slip ring and brush structure of the airborne structure have difficulties in heat dissipation. Usually, the temperature rise on the surface of the slip ring exceeds 80°C, which aggravates wear and further reduces the reliability of the slip ring brush

[0012] The disadvantage is: the slip ring of the airborne structure is difficult to adapt to the work at high speed, the wear of the brush increases at high speed, and the life of the electric slip ring decreases
