From the structure of the slip ring, we can basically understand its principle. The principle is to install an Electric Slip Ring on the rotating part, and then install a brush on the stationary part, so that it can achieve 360 degrees When rotating, the problem of wire winding is avoided, and information can be transmitted without obstacles.
How to maintain the service life of the Slip Ring Connector, is there any way to make it durable? 1. The contact pressure of the friction pair has the most influence on the wear. High contact pressure wear. When selecting the contact pressure of the friction pair, the designer should consider choosing the minimum contact pressure under the premise of reliable contact, so as to ensure the performance and service life of the friction pair 2. Adjust the contact between the slip ring brush wire and the metal ring so that the brush wire can be well pressed on the ring groove without affecting the rotation of the slip ring. If the pressure is not adjusted, it will cause virtual contact and the pressure is not enough. Excessive pressure will increase the friction torque, which will cause a lot of wear on the contact parts and shorten the service life of the slip ring. 3. Avoid using the slip ring in a high temperature or low temperature environment for a long time. The normal operating temperature of the slip ring is -45°C ~ +85°C. If it exceeds this range, the life of the slip ring will decrease rapidly, and even lead to direct damage. Except for 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 and strong alkali corrosion, so as to avoid rusting of metal parts and reduction of insulation performance of electrical components, except for special slip rings, such as acid and alkali resistant slip rings. 6. When purchasing a Conductive 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 method, and working speed , temperature, transmission signal type, etc. 7. The slip ring cannot bear the impact of external force, otherwise it will deform the slip ring and affect its internal structure. 8. Reasonable radial clearance in the process of installing the slip ring has a great influence on the life of the slip ring. If the radial clearance of the slip ring increases, the load area in the slip ring will decrease and the maximum rolling element load will increase , thereby reducing the slip ring life. 9. Avoid dust erosion when storing slip rings. If the environmental cleanliness 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 protection grades High requirements etc. 10. The hardness of the brush material and the number of frictional rotations (or distance) have a certain impact on wear. The higher the hardness, the better the resistance: the increase in the number of rotations increases the wear. However, hardness and rotations are not the main factors affecting wear. Friction The matching of slip ring and brush material is the key to high reliability and long life of friction operation.
