现在高速旋转的机械设备需要高速的齿轮传动装置,并且在高速下具有较好的可靠性。住友金属公司在设计和制造齿轮方面已经积累了60多年的经验,制造出了多种新干线机车齿轮传动装置。近来已经完成了节线速度为150米/秒(20000转/分),功率为1000千瓦的高速齿轮传动装置背对背的实体试验。试验中使用的是由滑动轴承支撑的淬火单斜齿轮,进行了噪声、振动、轴承温度,机械功率损失和临界速度等项目的试验。最后得到了有实用意义的结论。 Now high-speed rotating machinery and equipment require high-speed gear transmission, and has good reliability at high speed. Sumitomo Metal has accumulated more than 60 years of experience in the design and manufacture of gears and has manufactured a wide range of Shinkansen locomotive gearing. Recently, back-to-back physical testing of high-speed gear drives with a line speed of 150 m / s (20,000 rpm) and a power rating of 1000 kW has been completed. The test was carried out using a quenched single helical gear supported by a plain bearing with tests of such items as noise, vibration, bearing temperature, mechanical power loss and critical speed. Finally got the conclusion of practical significance.
