Insert gear used is relatively strong strength and toughness combined with relatively strong alloy tooth, as well as optimizing the number of rows of teeth, teeth toothy highly technical and unique alloy tooth shape, making it the biggest play of the cog very good wear resistance and excellent cutting performance. Above the surface of the steel teeth of the cast wear a new product to ensure that the machinery at work can be high speed, but also enhance the life of the drill tricone bit. tricone bit
Using the method of floating bearing, the floating product is the result of strength, wear resistance and high temperature characteristics of the new material, after the above surface treatment of the solid lubricant. tricone bit tricone bit to use to be able to endure temperatures of 250 ° C and are resistant to grease and abrasion. Bearing in reducing the relative speed of the line in the sub, but also slows the rise in the temperature of the friction surface, can greatly enhance the study and bearing life and high reliability, high drilling speed sub-ah work when used.
