The use of high-power slip ring

In advanced countries, these products have been gradually transformed by the military products for civilian products, standardization has been achieved in recent years, mass production, is widely used in security, factory automation, electricity, finance, instrumentation, aerospace, military, transportation, construction and other mechanical and electrical equipment. conductive slip ring, are high-tech products, is a variety of precision turntable, centrifuges and inertial navigation equipment, key components. As China's economy continues to develop, more and more civilian areas involved in the use of such products, slip rings for industrial automation systems control. A complete industrial brushes slip ring includes a stator part, the brush holder, and a rotor portion of the ring body, the two major components. Good brush brush holder fixed at both ends, to maintain a certain pressure and clamp ring body contact, to achieve the transfer current is applied. Usually during operation: between the brush and the pressure ring, ring body rotation swing brush, brush and brush holder gap between the work of the optimum operating temperature and routine maintenance, etc. To sufficient attention, which for the normal operation of High power slip ring and service life are essential. Between the brush and the pressure ring, the ring determines the collector contact resistance, but also determines the rotation of the friction and wear. Its relationship with the contact resistance and frictional pressure were proportional to the resistance too easy to produce sparks cause overheating and collector ring pitting phenomenon, the friction is too general acceleration collector ring wear affecting life. We usually let the brush ring between the body and the pressure was maintained 20KPa, pressure equalization between the various brushes, brush swing too loose then too, brush wear unevenly. Maintained between the brush holder and brushes moderately elastic, the contact surface is smooth and clean. This collector ring both rotate freely, electrical conductivity is good. The oscillating brush and brush and the gap between the brush holder, and if the activity is not too tight may cause flexible brush, the brush may cause jam.
