Technology and Principle of Slip Ring
The most important of the electrical slip ring is contact, first electrical slip ring in the structural design to ensure the reliability of the contact, to ensure that all of the line is turned on continuously, the electrical slip ring assembly by several important parts of the slip ring body, the noble metal contact point component, fixed bracket, the common core ball bearings, etc. The design and manufacturing process of large parts will affect the wear life of the slip ring, the slip ring mandrel electrical ring material is usually copper, brass, coin silver or gold materials, in the electrical ring surface need to plate multilayer precious metal substances act to reduce the impedance of the metal body in an instant rapid conduction extend wear life of the slip ring and reduce electrical noise. To ensure the sufficient contact between the brush and the electrical slip rings, electrical slip ring and is designed into a V shaped annular groove of the slip ring contact, in order to pass the signal and the current conduction, thus requiring brush used the materials has very good electrical properties, the pressure of elastic pressure on the slip ring should be appropriate, reduce the slip ring eccentric and shaking deviation, good abrasion resistance, friction torque is small, easy to maintain. Also consider shielding, impedance matching, noise voltage, etc.
electrical slip ring as a kind of precision machinery parts, level of technology directly determines the product quality is good or bad, experienced designers will take advantage of some of the common processing defects principle to make up the design, during engineering design, often encounter is how to connect with a functioning part, the electrical slip rings biggest role is to ensure the connectivity of the equipment in the free rotation, usually including the transmission of power, signals. Therefore, the characteristics of the preliminary manufacturing process is to make full use of 3D modeling tools and simulation tools, process full storm drain and displayed so as to grasp the level of good process design, to lay the foundation for all aspects of the behind process.
The slip rings is a precision part, every process has strict working requirements, and working personnel¡¤s working attitude for the quality of the product plays a crucial impact. Such as: the quality of the insulating material may cause leakage and so on.
Material requirements are fairly strict, the insulation properties and pressure resistance of insulating materials. The selection of contact materials, must have good electrical properties, but also wear-resistant, corrosion-resistant. There are some equipment in the outdoor, considerable temperature difference within one year, minus 30-40 degrees in the winter in some places, summer working environment temperature reaches 70-80 degrees, so we should take full account of these factors when material selection and testing.
Within a small volume slip ring connected voltage sometimes thousands of volts, current of several hundred amperes, there are a variety of complex signals simultaneously over a few hundred lines, how insulation between each passage, how the signal lines not to interfere with each other, is definitely not an easy thing to do, this is the designers need to carefully consider.
A designer can be expressed as one image by computer simulation publication. The modeling is usually the first step, a rapid prototyping technology system. Mechanical drawing of the construction work of any kind of economic accurate time and information, skilled in the art may have found a better way to local, to correct these problems may require modifications by modifying the original design or damage to the local. Drawings of this type are also used to the planed new process.
Processing, the details of the production processes determine the quality of the slip ring, in the slip ring production processes, preliminary design drawings, planning, should to pay particular attention to detail and craftsmanship key points.
To control the production quality of the slip ring, the first is to avoid errors in the design, occurred addition to usually work carefully, while two or more audit engineering drawings can also minimize the occurrence of errors. During the production, each product should firstly tested by the quality department personnel before bulk production, for item numbers, size, material, installation process , assembly of each slip ring component requiring must be strictly in accordance with the requirements on the engineering drawings. The bearing quality problems within the electrical slip ring may result in rotation were.
The design engineer may need to introduce value-added design to the existing local, but the factories may be reluctant to release its internal computer-aided design files for proprietary reasons. At the beginning of this task, the mechanical 3D slip ring product model more effective in assistance of communicating ideas design. In the production process, the control of the size must be strictly in accordance with the engineering drawings request processing, for the engineering drawings, it is necessary to go through the recognition of two designers before entering the production chain, each procedure should be completed to the next step after checking engineering drawings.
For process control and grasp need the human factor, and team co-ordination. Slip ring
as a kind of precision parts, The production process requirements are particularly strict, especially high number of rings, multi-channel, small size, miniature slip ring, due to the small size of this kind of slip ring, and the spacing between channels is not large, moreover, the internal structure is very sophisticated, a little small error could lead to the entire parts scrapped in the normal production process, staff training runs through the entire production process, the most important thing is not enterprise assets, is the people, products quality needs to be guaranteed by the people. Between the people and companies need to establish a relationship of mutual trust, it is the only way to achieve the best interests of the employees, by the way to achieve the company¡¤s goals and ideals. For the software facilities, training of staff is on the one hand, working hours try not to be too long, realize shift system, the best working time of a team is not more than eight hours, one-time continuous working time is preferably not more than a 1-hour, then 15-minute break. Work and rest to play to their enthusiasm and maximum efficiency, product quality can be best protected, to give up or to gain, there are only can give up firstly, and then can gain.
