Background

The electronic slip ring is an electrical component responsible for communicating the rotating body and transmitting energy and signals.

The traditional conductive slip ring is a carbon brush, but maintenance is often needed, and signals cannot be transmitted, so that more and more devices select a precision slip ring. The slip ring is used as an electrical component for communicating with the rotating body and transmitting energy and signals, and the whole instrument can not operate due to slight difference. Particularly, the prior sliding ring structure is complex, poor in stability and high in use cost.

SUMMERY OF THE UTILITY MODEL

Therefore, the general electronic slip ring with high stability and low cost is needed to solve the problems of poor stability and high use cost of the conventional electronic slip ring.

Furthermore, a fastener is arranged on the fixing ring far away from the driving shaft, and the fixing ring extends to the outside for fixing through the fastener.

Further, the fastener is fixed by pulling the terminal wire.

Further, the rotating speed of the slip ring body is less than 50RPM, and carbon brush contacts are adopted.

Further, the rotating speed of the slip ring body is more than 50RPM and less than 1000RPM, and a precious metal contact is adopted.

Further, the rotating speed of the slip ring body is larger than 1000RPM, and liquid conducting medium contacts are adopted.

In the universal electronic slip ring, one end of the slip ring is fixed on the axis, and the other end of the slip ring is floated and pulled to the outer fixing part, so that the slip ring is prevented from shaking; meanwhile, the slip ring is not directly connected with the driving shaft any more, the diameter of the slip ring is reduced, and the linear velocity is reduced, so that the abrasion of the electric brush is reduced, the service life is prolonged, the stability is high, and the use cost is low.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, in one embodiment, a universal electronic slip ring comprises a slip ring body 100, wherein one end of the slip ring body 100 is fixed on the axial center of a driving shaft 60 through a fixing ring 200, and the end penetrates into a gas pipe 400; the other end of the slip ring body 100 is extended to the outside through another fixing ring 200, and the end is mounted with a rotary joint 500 communicating with the air pipe 400.

The precision slip ring shell or plastic part is installed into the axle center, and the terminal wire is inserted to pull the rotating part. So that one end of the slip ring is fixed on the axis and the other end is floated and pulled on the outer fixing part.

In the universal electronic slip ring, one end of the slip ring is fixed on the axis, and the other end of the slip ring is floated and pulled to the outer fixing part, so that the slip ring is prevented from shaking; meanwhile, the slip ring is not directly connected with the driving shaft 60 any more, the diameter of the slip ring is reduced, the linear speed is reduced, the abrasion of the electric brush is reduced, the service life is prolonged, the stability is high, and the use cost is low.

For example, under the normal condition that the diameter of the slip ring is the same as that of the conventional slip ring, the linear velocity of the slip ring is reduced 1/2, the corresponding brush abrasion is obviously reduced, and the service life is improved by 3-4 times.

In the present embodiment, the axial center of the slip ring body 100 coincides with the rotation center of the drive shaft 60. The influence on the service life of the slip ring caused by the non-coaxial is avoided.

In the present embodiment, the axial centers of the air tube 400 and the rotary joint 500 coincide with the axial center of the slip ring body 100. The slip ring body 100 can rotate for 360 degrees coaxially with the slip ring body to transmit energy while rotating, so that the connection mode of the gas circuit is simplified under the condition of not increasing the space, and the tightness of the pipeline is ensured.

In the present embodiment, the fixing ring 200, which is far from the driving shaft 60, is provided with the fastener 300 and extends to the outside for fixing by the fastener 300. Specifically, the fastener 300 is fixed by pulling the terminal wire. The slip ring body 100 is rotated synchronously with the rotary member by inserting the terminal wire to pull the rotary portion to avoid complete fixation, which may cause damage or fail to achieve a desired service life. Wherein the fastener 300 is a bolt, screw or bolt.

The wear resistance of the slip ring produced from different raw materials is different. The strength, friction coefficient and current density of raw materials for manufacturing the slip ring have great influence on the abrasion of the slip ring during operation, so that the slip ring can be selected according to the rotating speed of the slip ring.

In this embodiment, if the rotation speed of the electronic slip ring is less than 50RPM (revolutions per minute), a carbon brush contact slip ring can be selected, and the price is relatively low. However, the carbon brush contacts are made of graphite, which is relatively easy to wear. If the rotation speed of the electronic slip ring is more than 50RPM and less than 1000RPM, a precious metal contact slip ring is adopted. If the rotation speed of the electronic slip ring exceeds 1000RPM, a liquid conductive medium contact slip ring is adopted.

In the combined design of the gas circuit and the slip ring body 100, the electronic slip ring in the embodiment can consider to reduce the overall circumferential size of the slip ring, and reduces the occupied space.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is specific and detailed, but not to be understood as limiting the scope of the present invention. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the utility model, and these changes and modifications are all within the scope of the utility model. Therefore, the protection scope of the present patent shall be subject to the appended claims.
