The advantage of this combined seal layout is that the oil slinger blocks most of the oil; the lubricant that enters the outermost rubber herringbone seal is rare; plus the common layout and device method of the herringbone rubber seal; The cover shell prevents oil leakage. Considering that the outer diameter of the slip ring is high; firstly, an oil slinger is arranged on the inner side of the seal ring of the casing; the slinger ring is divided into three sections in the circumferential direction; the device is bolted; the inner diameter Excellent fit with the outer ring of the slip ring; to prevent loosening, it should be spot welded to the outer ring of the slip ring.
In addition, an oil groove is arranged inside the two side walls of the sliding cover shell to prevent oil on the casing from dropping between the oil ring and the rubber seal. A ring of herringbone rubber sealing ring is arranged on the outer side of the casing; the rubber sealing ring The inner diameter of the manufactured inner diameter should be smaller than the outer diameter of the slip ring; the detailed scale is obtained according to the selected raw materials and the experiment; the pressure of the lip to the sealing surface is obtained by the deformation of the rubber itself after the device; the lip is filled with grease. The choice should be based on factors such as wear resistance and elasticity; the sealing ring is supplied in three stages per turn. It is necessary to adjust the concentricity of the sliding cover and the slip ring first when installing the device; when installing the rubber sealing ring; The orientation of the device on the casing; whether the sealing of the inner lip of the sealing ring and the sealing surface can be tight; whether the proximity is common on the circumference; if adjustment is required; the method of circumferentially slotting the rubber sealing ring can be adopted to prevent the sealing The pleats of the ring; so that the inner lip of the sealing ring fits well with the sealing surface. The lip is filled with grease when the device is officially installed; each piece is glued with a sealant; the first interface is placed directly above the orientation. Then use Supplyed After the steel compression platen is fixed.
