Abstract
The invention discloses a slip ring which comprises a brush tow and a collecting ring, wherein the brush tow comprises two tows forming an included angle, a brush head is arranged at the top end of each tow, one end, in contact with the collecting ring, of the brush head is arc-shaped, the arc-shaped end is attached to the arc of the collecting ring, and a tension spring is arranged between the two tows. The invention can accurately adjust the acting force between the brush head and the collecting ring through the tension spring, so that the brush head works more stably, and the service life of the slip ring is prolonged.
Description
Technical Field
The invention relates to the field of slip rings, in particular to a slip ring.
Background
The slip ring is also called a conducting ring, a collecting ring, a conducting slip ring, an electric brush, a rotary joint, a rotary electric joint and the like, and is widely applied to security protection, wind power generation, factory automation, electric power, finance, instruments, chemical engineering, metallurgy, medical treatment, aviation, military, ships, transportation, buildings and other electromechanical equipment. Slip rings there are basic classes of precision instrumentation slip rings: according to different devices, the requirements on the slip ring in the aspects of size, appearance structure, speed, frequency, transmission signals and the like are high; industrial conductive slip ring: most of the slip rings are slip rings, the size is large, and the requirements on temperature and service life are high; military slip rings: explosion-proof and earthquake-proof requirements are high; marine vessel slip rings: the requirements on water resistance and corrosion resistance are high; wind wheel slip ring: the protection level is higher, mostly is the hollow shaft, and a small number is cap formula sliding ring. The conducting ring can improve the system performance, simplify the system structure and avoid the wire from being twisted due to the rotation of the movable joint.
In many precision fields, the parameter requirements on the slip ring are very strict, especially the pressure between the brush head and the collector ring is too high, so that the brush head is easily worn, and the brush head is easily poor in contact and generates sparks when the pressure is too low.
An effective solution to the problems in the related art has not been proposed yet.
