美国休斯公司的密封轴承钻头(滑动轴承和X系列牙轮钻头),现在都采用一种所谓“真空—压力法”灌注润滑脂,从而大幅度地提高钻头的质量和性能。这种新工艺,有利于使钻头的轴承部分、储油定和油道内全部充满润滑脂,同时还能检验整个润滑系统的密封性,保证焊接质量。
Hughes Bearings (plain bearings and X-Series cone-roller bits) from Hughes now use a so-called “vacuum-pressure” method of pouring grease to greatly improve drill bit quality and performance. This new technology is conducive to the bearing portion of the drill, the oil reserves and the oil filled with grease, but also to test the sealing of the entire lubrication system to ensure welding quality.
