JOURNAL FREE ACCESSThe purpose of the present research is to determine how the working efficiency and roughness of surface in the superfinish are influenced by surface speed of work or by the frequency and amplitude of motion of the superfinishing stone. As the result of the systetmatic research, the following conclusions were obtained. Namely, the characteristics of superfinish are seriously influenced by the resultant of circumferential and sidewise cutting speeds, angle of cutting lines and the amplitude of stone. Then, as the numerical values, for the first stage of superfinish, resultant speed of 20-25 m/mn and angle of 30°-40° are suitable and for the second stage of superfinish 50 m/mn and 5°-10° are suitable.View full abstractDownload PDF (732K) -

JOURNAL FREE ACCESSNew formulae of good approximation are given for estimating the amount of the effective involute gear profile removed by rack-shaped cutters. Three cases are considered where the cutting profile and the addendum line of the cutter form a sharp corner, where they have chamfering, and where they are tied together by a circle. It is shown that practically the effect of these tips rounding on the amount of undercutting can be neglected and that it is sufficient to take the first case alone into consideration for the designing of cutters. The maximum radius of rounding circle free of undercutting is estimated accurately.View full abstractDownload PDF (767K) -

JOURNAL FREE ACCESSThe measuring method by inserting single racks has hitherto been used for helical gears in U.S A., etc., because of its several advantages over the ball inserting method ; but its fundamental theory has not been cleared up in our country. The author solved equations of involute helicoid curved surface to make it clear completely, derived calibration methods to the manufacturing errors in measuring racks, and discussed relative merits of various kinds of racks. Application of the single rack method to the analysis of helical gears will make the measurements more stable, the calculations easier, and the measurement of true eccentricity of teeth simpler, than by the ball inserting method. Moreover, the measuring instruments for this method may be available in usual gear cutting shops. Therefore, this method will be popularized as a convenient one. Thus, the analyzing method of helical gears and calibration method for measuring rack were described as applications of this theory.View full abstractDownload PDF (561K) -

JOURNAL FREE ACCESSAccording to the present methods, we have two difficulties in calculation of shifted helical gears by cutters with standard normal tooth profile, because of the existence of helix angle β : one is the displacement of cutting pitch circle, and the other the variation of cutting face pressure angle of gears. So, I will suggest to adopt the "imaginary pitch circle" which is the same as that of standard spur gears and unrelated to the helix angle, and to utilize the '''table of β-Vv-V function" which is newly derived. Then, the calculation of helical gears would be so simple as that of spur gears.View full abstractDownload PDF (933K) -

JOURNAL FREE ACCESS(1) Various methods of measuring the pressure angle of hobs having rake angle are investigated. (a) Measurements with a Universal Measuring Microscope. (b) Measurement with a projector. and discussed on the results practically measured. (2) On measuring the tooth profiles of hobs having large lead angles, a method with a projεctor is investigated. A formula calculating the model forms of projected profiles is introduced. (3) When we measure the pressure angles of hobs with a projector, if the lead angle is large, the projected pressure angle is not equal to the true normal pressure angle. A brief formula calculating the difference is obtained.View full abstractDownload PDF (647K) -

JOURNAL FREE ACCESSWhen the tooth-forms of worms or wheels are given, the tooth-forms of mating gears are found as the envelopes of the given gears in motion. The surfaces of contact or contact lines can also be found in this same prcedure. There are many ways pf mathematical treatment in making envelopes, but the one, in which the original figure is expressed according to rectangular co-ordinates, and the condition of envelope is obtained as the Jacobian of the expression of the moving figure is put equal to zero, will be most convenient. In this paper, there are discussed on some tooth-forms and surfaces of contact of cylindrical worms, globoid worms and enveloping worms, which are thought formerly difficult to treat.View full abstractDownload PDF (562K) -

JOURNAL FREE ACCESSIn the previous paper we reported results of the experiment on forced lubrication for the purpose of cooling of ball bearing, but applied load on the bearing was light. We repeated the same experiment as previously reported at higher load. Further we measured change of electric contact between outer and linner races of the bearing and obtained some information about the formation of oil film in the bearing.View full abstractDownload PDF (1074K) -

JOURNAL FREE ACCESSIn order to know the mechanism of the relaxation of machine-elements such as cotters, screws, etc., an experiment was performed on a tapered cotter. Repeated blows were delivered on the cotter by a blow-hammer from the direction opposite to that of inlaying. By measuring the number of blows to the completion of the relaxation it was proved that the relaxation came about owing to the storing up of small displacements by repeated blows ; and by theoretical consideration the relation between the energy delivered on the cotter and the work due to resistance against drawing out was formularized.View full abstractDownload PDF (498K)
