T Yamanaka; C Naruse; S Haizuka
Crossed helical gears fail mainly by scuffing. Power transmission is low, because the Hertzian pressure in the small elliptic contact area is very high, and the sliding velocity between two contacting tooth surfaces is very high compared with other kind of gears.
However, crossed helical gears have important advantages, since they are easy to produce and their engagement is not influenced by mounting errors in center distance or shaft angle. This study presents some new ways of improving the load carrying capacity of crossed helical gears.
The influence of lubricating oil, tooth surface treatment, and tooth form on the limiting load for scuffing was studied experimentally. The results were summarized and formulas were established in view of practical design., SOC TRIBOLOGISTS & LUBRICATION ENGINEERS, 出版日 2000年01月, Society of Tribologists and Lubrication Engineers（STLE），Tribology Transactions, 43巻, 1号, 掲載ページ 100-108, 英語, 1040-2004, WOS:000084789300015 - A combined measurement system for discriminating complex resistances affecting ski sliding

Shoji Haizuka; Takaaki Kikusaki; Chotaro Naruse
The study of friction loss of spur gears was carried out, using test gears with a center distance a=183 mm. The load for the test gears was comparatively high, i.e. the load was applied up to about 60% of the Hertzian pressure of tooth surface strength in endurance strength range and the range of circumferential velocity was extended up to about 120 m/s. Generally speaking, we obtained that, the higher the lubricating oil viscosity, the lower the friction loss. Further we found that a most suitable oil viscosity in order to reduce the friction loss exists for the gear unit, including not only the test gears but also the bearings and the gear box. As far as tooth form is concerned, the cutter pressure angle α0=25° gives the lowest friction loss for the gear unit., Japan Society of Mechanical Engineers, 出版日 1999年, JSME International Journal Sires C, 42巻, 4号, 掲載ページ 1041-1049, 英語, 1344-7653, 0033495485 - Study on Tooth Surface Strength of Spur Gears PartＩ: Experimental procedure and Determination of Tooth Surface Strength

The wear of case-hardened spur gears running under a constant high load was studied. The lubricating oil viscosity, kinds of additives and their amounts, and lubricating oil temperatures were changed. In order to study the effect of oil temperature on the wear of the tooth surface, the temperature of the oil was changed from 60℃ to 90℃ for the same sample. Moreover, the temperatures of three kinds of oils which have very different viscosities at room temperature, were varied between 60℃ and 105℃ while the oil viscosity was unchanged. It was shown from the test results that tooth surface wear is not greatly affected by the amount of ZDTP antiwear agent, but EP additives are less effective against wear than ZDTP additives. The viscosity of lubricating oil and its temperature greatly affect the wear of the tooth surface. Combining all the wear data with those of the tooth surface strength, it was observed that the higher the load, the wider the scattering of wear, and also in the case of the same running load, the lower the wear, the longer the life of the tooth surface strength., 一般社団法人日本機械学会, 出版日 1995年, 日本機械学会論文集C編, 61巻, 585号, 掲載ページ 2078-2085, 日本語, 0387-5024, 110002381899, AN00187463 - Study on Limiting Load for Scuffing and Specific Wear of Spur Gears(Effects of Labricating Oil and Tooth Form)(共著)

In order to study the effect of lubricating oil temperature on tooth surface strength, the temperature of three kinds of oils which have very different viscosities at room temperature was changed between 60℃ and 105℃ under the condition that the viscosity is kept constant. It was shown that the tooth surface strength of case hardened gears is not affected much by the temperature change, but in the case of tempered gears, the tooth surface strength decreased remarkably with increasing oil temperature. Further, so as to study the effect of hardness on tooth surface strength, the effect of the hardness of tempered gears (HV≒285〜550) and the effective case depth of case hardened gears (h_≒0.2〜1.1mm) on the tooth surface strength were examined and discussed., 一般社団法人日本機械学会, 出版日 1994年, 日本機械学会論文集(C編), 60巻, 580号, 掲載ページ 4310-4317, 日本語, 0387-5024, 110002381364, AN00187463 - Studies on Tooth Surface Strength of Spur Gears(Effect of Oil Temperature and Hardness of Gears)

Carbon steel has been used as spur gear material. It is very important to find a way of reducing the friction loss of spur gears, and there are many methods of achieving this. Here we chose the method of selecting material combinations in a wide scope, i. e. , not only the steel material, but also the materials of phosphor-bronze and cast iron. furthermore, for steel material, we chose various kind of coatings, that is, nitriding and phosphate coating. As a result, we induced a very low friction loss by using phosphor-bronze gears which were combined with a nitrided gear or a case-hardened gear. Some considerations were carried out for these phenomena., 一般社団法人日本機械学会, 出版日 1991年, 日本機械学会論文集C編, 57巻, 541号, 掲載ページ 3100-3106, 日本語, 0387-5024, 110002380013, AN00187463 - Study on Frictional Loss of Spur Gears(Concerning the Influence of Tooth Form, Load, Tooth Surface Roughness and Labricating Oil)(共著)

Improvement of the load-carrying characteristics of helical gears is one of the most important problems today. But the experimental results of these kinds of studies are comparatively scarce. For this purpose, we took up the subject of the frictional loss and the temperature rise of the teeth of the helical gears. Considering these situations, we studied the frictional loss of helical gears as a function of many factors, i.e., helix angle. sliding velocity of tooth surface, load, viscosity of lubricating oil and chemical construction of lubricating oil. The frictional loss grade of the helical gears decreases with increasing sliding velocity and viscosity of lubricating oil and increases with the helix angle and load. Further the frictional loss grade is very low when the synthetic oil is used. Finally, the relationship between the temperature rise of teeth and frictional loss was expressed with an empirical formula., 一般社団法人日本機械学会, 出版日 1990年, 日本機械学会論文集 C編, 56巻, 531号, 掲載ページ 3060-3067, 日本語, 0387-5024, 110002379375, AN00187463 - ハイポイドギャの負荷特性に関する研究(スコ-リング発生荷重、摩擦損失及び温度上昇について)(共著)

The load carrying characteristics of hypoid gears were investigated by means of test equipment of the power circulating type. The limiting load for scoring and friction loss of the hypoid gears. and temperature rise of the teeth of the gear wheel of the hypoid gears were measured. The relationships between these results were also summarized in order to assimilate the general tendencies of these factors. Furthermore, these hyoid gear results were compared with those of the spur gears. Both mineral oils and synthetic oils were used as lubricants. The kinds of oil markedly affected the friction loss and consequently influenced also the temperature rise of the gear teeth., 一般社団法人日本機械学会, 出版日 1989年, 日本機械学会論文集 C編, 55巻, 514号, 掲載ページ 1446-1453, 日本語, 0387-5024, 110002391755, AN00187463 - 平歯車の歯面強度に関する研究(潤滑油が調質歯車と浸炭焼入れ歯車に及ぼす影響)(共著)

Many studies on tooth surface strength have been reported but they are mainly reports on tempered steel. So, it can be said that sufficient data to design the case hardened steel for tooth surface strength has not been published. Therefore, spur gears were tested for tooth surface strength under several lubricating conditions and several surface treatments of test gears. The tooth surface strength of case hardened gears is not so affected by the difference of the viscosity of lubricating oils, as are the tempered gears. The EP additive is effective for the tooth surface strength of case hardened gears but it is not effective for the tempered gears. The difference of the chemical structure of the lubricating oils has some effects on the surface strength of gears. The effective case depth of case hardened gears is an important factor to determine the tooth surface strength., 一般社団法人日本機械学会, 出版日 1987年, 日本機械学会論文集C編, 53巻, 487号, 掲載ページ 855-863, 日本語, 0387-5024, 110002390107, AN00187463 - 平歯車の歯面強度に関する研究--潤滑油が調質歯車と浸炭焼入れ歯車に及ぼす影響

There are many factors, which have effects upon the load carrying characteristics of the spur gears. The surface roughness of tooth and viscosity of lubricating oils, furthermore the concentration of additives are the very important factors for the determining the load carrying characteristics of the spur gears. As main factors for determining the load carrying characteristics, the limiting load for scoring and the specific wear were chosen here. The roughness of the tooth surface for our experiments was in the range of 1.1〜7.5 μm. The kinematic viscosity of the lubricating oil for the experiments was 2.9〜4.0 ×10^<-6> m^2/s at 90℃. The experimental equipment was the FZG spur gear testing machine and the test gears had also the original tooth form of FZG test gears but our test gears were specially crowned in direction of tooth trace and effective width was reduced to b=8 mm in order to get the higher Hertzian pressure. This tooth width is very narrow in comparison with the original one., 一般社団法人日本機械学会, 出版日 1986年, 日本機械学会論文集C編, 52巻, 483号, 掲載ページ 2906-2913, 日本語, 0387-5024, 110002389727, AN00187463 - Influencs of Surface Roughness and Viscosity of Lubricating Oils on Limiting Load for Scoring of Spur Gears
