There is not welding integral type ventilation brake disc assembly

There is not welding integral type ventilation brake disc assembly, including the brake disc and with the spacer ring of the coaxial assembly of brake disc the equipartition sets up the ventilation hole of radial extension on the brake disc, the integrative casting shaping of brake disc the peripheral circumference equipartition of following of inner circle of brake disc sets up the screw hole, the spacer ring pass through the bolt with the brake disc is connected. The brake disc adopts casting integrated into one piece technique, and the formation in ventilation hole is solderless connection, and intensity is high, and stability is good, need not to carry out the welding seam to the brake disc and detect a flaw, be particularly suitable for in cold areas and offshore drilling platform and go up use, maintenance cost in the greatly reduced use, the brake disc adopts split type connected with the spacer ring, processing, simple to operate, and material utilization rate is high, only changes a consume brake disc when maintaining, has reduced maintenance cost.
