  The structure character and function of tricone bit

  1. With floating bearing structure, the floating components are made of new materials with high strength, high elasticity, high temperature resistance and high wear resistance. The surface is treated by solid lubricant. In reducing the relative linear velocity of the bearing, the friction surface temperature rise can effectively improve the bearing life and bearing reliability of high drilling pressure or high speed drilling process.

  2. High precision metal sealing. Metal seal designed by a pair of processing of metal sealing ring for bearing axial dynamic seal, two high elastic rubber circle of power in the palm and cone sealing area as a static seal, optimization of the seal compressed volume ensures that the two metal ring sealing surface always keep good contact.

  3. The steel ball locks the cone and ADAPTS to the high speed.

  4. The all-rubber storage bag which can limit the pressure difference and prevent drilling fluid from entering the lubricating system provides a good lubrication guarantee for the bearing system.

  5, using resistant to high temperature of 250 ° C, resistance to wear and tear of the new type of grease.

  6, button bit, USES the high strength and high toughness carbide teeth, optimal design of tooth row number, number of teeth, teeth height and unique alloy tooth shape, give full play to the button bit high abrasion resistance and excellent cutting ability. A new type of abrasion resistant material is applied to the surface of the teeth of steel teeth, and the cutting tooth life of the drill bit is improved while maintaining the high mechanical drilling speed.
