The Application of Moving Frame in the Calculation of Spiral Bevel Gear’s Principal Curvature

Wang Yuqing,Liang Jian

Strategic Study of CAE 2001, Volume 3, Issue 12,   Pages 68-70

Abstract:

the calculation of contacted points´ principal curvature is the key to determine contacted area. Traditionally, the method of determining principal curvature is to make use of the theory of mesh and coordinate transform. However, this method is complex. In this paper, based on the feature of curve surface, moving frame and co-differential are employed to give a sententious, effective algorithm of principal curvature. Then, according to the formulation of contacted area, an application example is given. This algorithm can be used for calculation of principal curvature in all kinds of curve surfaces.

An investigation into the heat transfer characteristics of spiral wall with internal rib in a supercritical

TANG Renhu, YIN Fei, WANG Haijun, CHEN Tingkuan

Frontiers in Energy 2007, Volume 1, Issue 3,   Pages 300-304 doi: 10.1007/s11708-007-0043-5

Abstract: Within the pressure range of 9–28 MPa, mass velocity range of 600–1 200 kg/(m · s), and heat flux range of 200–500 kW/m, experiments were performed to investigate the heat transfer to water in the inclined upward internally ribbed tube with an inclined angle of 19.5 degrees, a maximum outer diameter of 38.1 mm, and a thickness of 7.5 mm. Based on the experiments, it was found that heat transfer enhancement of the internally ribbed tube could postpone departure from nucleate boiling at the sub-critical pressure. However, the heat transfer enhancement decreased near the critical pressure. At supercritical pressure, the temperature difference between the wall and the fluid increased near the pseudo-critical temperature, but the increase of wall temperature was less than that of departure from nucleate boiling at sub-critical pressure. When pressure is closer to the critical pressure, the temperature difference between the wall and the fluid increased greatly near the pseudo-critical temperature. Heat transfer to supercritical water in the inclined upward internally ribbed tube was enhanced or deteriorated near the pseudo-critical temperature with the variety of ratio between the mass velocity and the heat flux. Because the rotational flow of the internal groove reduced the effect of natural convection, the internal wall temperature of internally ribbed tube uniformly distributed along the circumference. The maximum internal wall temperature difference of the tube along the circumference was only 10 degrees when the fluid enthalpy exceeded 2 000 J/g. Considering the effect of acute variety of the fluid property on heat transfer, the correlation of heat transfer coefficient on the top of the internally ribbed tube was provided.

The Innovation-design of Pan-spiral Bevel Gear and Its Secondary Development of Applications

Liang Guiming

Strategic Study of CAE 2001, Volume 3, Issue 7,   Pages 70-78

Abstract:

Bevel gears and hypoid gears are more complex transmission equipments. To avoid the change of shaft angles, the zero modification transmission (i.e.x1 + x2 = 0) tooth systems are adopted and had been used about one century .This paper introduces a new tooth system, NON-ZERO modification transmission (x1+ x2≠0), keeping the invariable shaft angle. After secondary development, this innovation may be manufactured by updated machine tool and be applied successfully to engineering vehicle, military production, vertical machine tool, locomotive, speed boat, as well as oil field, coal mine and cement industry. The new-type bevel gears have many advantages, such as multiple capacities, high reliabilities, long lives, small dimension, low noise and high adaptability. They not only may substitute the whole Gleason bevel gear system but also accomplish the function which Gleason can't. Hence the new type bevel gears will open vast vistas for application.
