The wearing angles of the travellers while running at spindle speeds between 13000-15000 r. p. m. and the depth and length of wear of rings and travellers were measured. Various type of rings and travellers were used in these tests, including anti-wedge rings and travellers made in Shanghai. The results show that the wearing angles of travellers are 14°30', 22.25' to the coordinate plane XOY, YOZ respectively.

The wearing angles of the travellers while running at spindle speeds between 13000-15000 r. p. m. and the depth and length of wear of rings and travellers were measured. Various type of rings and travellers were used in these tests, including anti-wedge rings and travellers made in Shanghai. The results show that the wearing angles of travellers are 14°30', 22.25' to the coordinate plane XOY, YOZ respectively. From a simple analysis of the moments acting on the traveller, the cause. of wedging of traveller is discussed, the most serious one being probably the inclined angle A within XY plane. Experiments showed that the working life of travellers are widely different on different rings. Some travellers worked as long as 449 hours, while others had been changed 19 times within the same period. Measurements on those rings and travellers showed that the longer the working life, the greater the ratio of T/t (T-the distance between horns of traveller, and t-the width of the ring web.) and the longer the wearing length. Therefore it is considered that the geometric shape of ring and traveller should suit each other. As an example a ring flange is redesigned under certain simplifications. The author concluded that travellers could run at higher speeds without abnormal wear, burning or wedge, under following conditions: 1. The contact surface between ring and traveller should be larger than those used under ordinary speeds. 2. The center of gravity of the traveller should be low. 3. The contact position on the ring flange should be higher. 4. The space between top surface of the ring and traveller should be large enough to allow yarn to pass through. 5. It is better to use a narrower width of flange. 6. The width of ring web should be narrow. The distance between the horns ends of traveller should be kept at a proper ratio to the flange width of the ring. 7. The sharp angle of the flange curve should be avoided.

通过作用在钢絲圈上各力矩的分析,得出鋼絲圈在运动中是要产生偏斜的。这种偏斜与鋼絲圈重心位置与其在鋼令上接触点的高度有关。由于这种偏斜的产生,且达到使鋼絲的外脚碰及钢令外側壁时,即引起了楔住。認为在子午面中的倾斜是引起楔住的最大原因。除了楔住是运轉上的麻烦外,另一点是钢絲圈在高速下的过快磨損。了对这二点作了討論,提出了在設計鋼领与鋼絲圈的弧形时以及它們相互配合上所应遵循的几点条件。最后,簡單地举例說明了钢令弧形的设計。

This article gives the test results of bending, wearing and contact fatigue of the teeth of the modular cast iron (QT60-2, Normalizing) gear. It also shows that normalizing QT60-2 is better than tempering steel 45 in contact endurance and anti-wear on tooth surface. The 290-690 Diesel engine gear teeth can be made from this type of cast iron in place of steel 45 with sufficient strength. A prelimanary analysis of the fatigue pitting on the tooth surface of normalizing QT60-2 gear is also made.

本文介绍了球墨铸铁(QT60—2正火)齿轮的轮齿弯曲、磨损及齿面接触疲劳等方面的试验结果;指出QT60—2(正火)齿轮的齿面接触疲劳强度及耐磨性均较45~#钢(调质)齿翰为好,用QT60—2(正火)代替45~#钢制造的290—690型柴油机齿轮具有足够的强度。最后还对QT60—2(正火)齿轮的齿面疲劳点蚀作了初步分析。

This paper deals with the engagement of gears with circular arc profile in normal plane at the presence of errors on center distance and depth of cut. It is pointed out that in the above conditions, the instantaneous transmission ratio remains unchanged, while the theoreticaI point of contact of teeth will shift. A formula for calculating the Position of the contact point is given. This paper also describes the conditions for ensuring two engagement lines with double concave-convex circular arc profile....
