From the structure of the conductive slip ring, you will basically understand its theory. The theory is to install the electric slip ring on the rotating part, and then install the electric brush on the stationary part, so that you can achieve 360 degrees When rotating, the problem of wire entanglement is avoided, and information can be transmitted without obstacles.

The conductive slip ring will be durable according to the following methods:

1.The contact pressure of the friction pair has the greatest influence on the wear, and the contact pressure has a large amount of wear. The designer should choose the minimum contact pressure under the premise of reliable contact when choosing the contact pressure of the friction pair to ensure the performance and service life of the friction pair.

2.It is best to adjust the contact between the brush wire of the slip ring and the metal ring to make the brush wire press well on the ring groove without affecting the rotation of the slip ring. If the pressure is not adjusted, it will cause virtual contact, insufficient pressure, and excessive pressure. If it is too large, it will increase the friction torque, make the contact part wear a lot, and shorten the service life of the slip ring.

3.Avoid long-term use of slip rings in high temperature and low temperature environments. The normal use temperature of slip rings is -45℃～+85℃. If the temperature exceeds this range, the life of the slip ring will decrease rapidly, and it may even cause direct damage. Except special slip rings, such as high temperature and low temperature resistance.

4.When using a slip ring, install the slip ring correctly according to the installation instructions of the slip ring manufacturer, and avoid exceeding the maximum voltage and current that the slip ring can withstand during use.

5.It should be used in a place where there is no sand layer, no corrosive gas, no strong acid, strong alkali corrosion, so as to prevent metal parts from rusting, electrical components reduce insulation performance, except for special slip rings, such as acid and alkali resistant slip rings.

6.When purchasing a slip ring, provide relevant parameters to the slip ring manufacturer according to the equipment requirements, so that the manufacturer can accurately provide the product or provide you with a design plan. These data include the number of channels, rated maximum current and voltage, wiring mode, working speed, temperature, Transmission signal type, etc.

7.The slip ring cannot withstand the impact of external forces, otherwise it will deform the slip ring and affect its internal structure.

8.In the process of installing the slip ring, the reasonable radial clearance has a great influence on the life of the slip ring. If the radial clearance of the slip ring is increased, the load area in the slip ring will be reduced, and the maximum rolling element load will increase, which will reduce slip ring life.

9.Avoid dust erosion when storing slip rings. If the environmental clarity does not reach a certain level, dirt will be attached to the surface of the metal ring, which will also cause virtual contact or increase the resistance value, except for special slip rings, such as those with high protection levels, etc.

10.The hardness of the brush material and the number of frictional running revolutions (or distance) have a certain effect on the wear. The high hardness has good resistance: the number of revolutions increases, the wear increases, but the hardness and the number of revolutions are not the main factors affecting wear. The matching of ring and brush material is the key to high reliability and long life of friction operation.。
