开式齿轮是主要噪声源之一。美国克利夫兰的富兰克林石油公司生产的一种叫做“Tufgear”的新型润滑脂,可以用来降低齿轮的噪声,还能对齿轮起保护作用,使用时间也较长。由一家大型印刷机制造厂进行的试验表明,这种润滑脂可降低噪声4～5dB(分贝),使该厂的噪声指标达到不超过80dB的要求。这种润滑剂以二硫化钼为基础制成。它与齿轮表面作用形成一层分子薄膜,这层薄膜能承受高达7031kgf/cm~2的压力。它还其有不吸附污物和灰尘的特点。与普通的高粘度润
Open gear is one of the main noise sources. A new grease called “Tufgear” from Franklin Oil Company in Cleveland, USA, can be used to reduce gear noise and protect the gears in a long time. Tests conducted by a large printing press manufacturer show that this grease reduces noise by 4 to 5 dB in decibels, making the plant’s noise figure up to 80 dB. This lubricant is based on molybdenum disulfide. It forms a layer of molecular film on the surface of gear, which can withstand the pressure up to 7031kgf / cm ~ 2. It also has the characteristics of non-adsorption of dirt and dust. With ordinary high viscosity run
