Under his leadership, a series of new products have been developed: for example, with his help, Comrade Qian Zhenxin of Shanghai Xinzhong Company manufactured precision measuring blocks; The first manual precision gear grinding machine in New China was designed and manufactured, and the first gear shaper cutter was ground. Many new technologies, such as random grinding, precision grinding, gear technology, etc., have reached the international level at that time. During this period, four kinds of machine tools were developed to achieve mass production.
at the same time, in production management, he led the formulation of a set of scientific management systems for production and workers' training, which laid a good foundation for the production of Shanghai Machine Tool Plant. Lei Tianjiao became the pioneer of China machine tool industry. On March 6, the Third Hospital was established, and Lei Tianjue was appointed as the vice president and chief engineer of the Chinese Academy of Mechanical Engineering of the First Ministry of Machinery Industry.
as the technical leader of the institute, he has spent a lot of time and energy in planning the professional direction of the institute and guiding various research topics for many years. He has made outstanding contributions in hydrostatic bearing, hydrostatic nut, hydraulic transmission, gear transmission, precision indexing, precision machining and measurement. For example, he helped comrades engaged in gear professional research to study new tooth profiles. He studies hydrostatic bearings, which can be used in grinding machines to improve the surface roughness of workpieces by one or two grades. He also worked out the graduation with elastic average effect, and personally participated in the experiment. During the "Cultural Revolution", many studies were interrupted, and he sent the laboratory to work from his leading position. At this time, he still devoted himself to research and continued the research on "hydrostatic nut" under possible conditions, so that the screw and nut could have no solid contact at all. During this period, a multi-pump hydrostatic guide rail was also developed, so that the oil film thickness of the guide rail can reach one micron. It was not until 1969 that he transferred to the cadre school that he had to completely stop his technical research work. AAGage, Inc. of the United States published a patent on multi-tooth indexing. When the news reached China, Lei Tianjiao keenly noticed that this technology had great potential in high-precision indexing technology based on his years of research experience in gear grinding machine indexing. He believes that the teeth of multi-tooth disc can be made into elastic teeth by using the principle of closed errors in the circumference and elastic compensation, so that high accuracy can be obtained. According to this idea, he immediately carried out the experiment of multi-tooth indexing disk with elastic teeth, and the results completely verified his expectation. He published this result in the form of scientific research briefing. Just as this achievement was widely concerned by domestic colleagues, many units successively carried out the research and development of multi-tooth indexing discs with elastic teeth, when the "Cultural Revolution" began, he was forced to stop this research.
as soon as he resumed his work after the "cultural revolution", he personally led a scientific research team and developed a graduation device with a graduation density of one cent (15 times higher than that of the multi-tooth graduation disc with the highest graduation density in the world at that time) and equipped with a small angle generator. The resolution of the small angle generator reaches one hundredth of an arc second. In order to overcome the manufacturing difficulties of multi-tooth indexing table, he put forward elastic teeth; Furthermore, the tooth structure of "independent elastic teeth" is creatively put forward, and its superiority is proved by experiments. Since then, he has devoted himself to popularizing and applying this achievement. Because the precision of multi-tooth precision indexing disc with elastic teeth exceeds the highest precision indexing instrument in the world, and it has advanced manufacturing technology, it can replace the existing precision indexing turntable. He is contributing to the improvement of the quality of mechanical and electrical products in the motherland and striving for export to earn foreign exchange.
Journal of Mechanical Engineering is an academic journal of natural science and technology in China. It is regarded as an authoritative publication with strong theory in China universities and academic circles. Since its inception, it has been hiring experts from the older generation, such as Lei Tianjue, Qian Xuesen, Zhuang Qianding and Wu Zhonghua, as members of the editorial board. Since the founding of the People's Republic of China 4 years ago, Journal of Mechanical Engineering has made outstanding achievements for the development and exchange of mechanical science and technology in the motherland. The Journal of Mechanical Engineering resumed publication after the destruction of the "Cultural Revolution", and Lei Tianjue was appointed as the editorial director of the Journal of Mechanical Engineering. Under his specific guidance, the academic level of the journal has been improved and its reputation has been expanding day by day. He carefully examines and checks every article published. He insisted on carrying out the direction of science and technology oriented to economic construction and vigorously advocated the style of combining theory with practice. In the opening speech of the enlarged meeting of the editorial board in 1986, he clearly pointed out: "It is difficult for us to find the meaning of its existence except for serving the construction." It emphasizes the correct direction of "publications facing readers and serving readers". He compared some flashy articles to "like a nut with a thick shell and a small kernel". By Su Dongpo's remark that Yang Xiong was "ignorant in writing", he warned the editorial department to make unremitting efforts to improve the style of the journal. In 1987, the editorial board and editorial department decided to add the English version of Journal of Mechanical Engineering. To this end, he personally wrote the inaugural speech, carefully reviewed all the English manuscripts, and published the inaugural issue in 1988 on time and with good quality and quantity.
lei tianjue was born in Beijing on January 29th, 1913, and his ancestral home is Liuyang county, Hunan province. He was born in an intellectual family, and his father Lei Guangyu studied the philosophy of Wang Yangming School, advocating knowing and acting, and opposing the inconsistency between words and deeds. Because the education he received was based on patriotism and hard work to build the country, and the influence of his family, he was determined to develop his country's industry and revitalize China from an early age, which became his lifelong pursuit. After graduating from Lei Tianjue University, he stayed in school to teach for one year, and then worked in Nanjing "Ordnance Department" for one year, that is, he joined the machine factory (named Central Machine Factory in the autumn of 1939) established by the then Resources Committee. From 1942 to 1947, he was selected to go to the United States P&; W and other companies practice machine tool and tool manufacturing. When he returned to China in the winter of 1947, the Nanjing National Government forced him to go to Taiwan Province, but he escaped, so he used this time to devote himself to teaching engineering mathematics by himself until liberation. He was a deputy to the First National People's Congress and a member of the Fourth and Fifth Chinese People's Political Consultative Conference. Member of the 6th and 7th Chinese People's Political Consultative Conference Standing Committee. Since 1955, he has been an academician of China Academy of Sciences. He used to be a director of China Mechanical Engineering Society and the chairman of China Mechanical Engineering Society's Mechanical History Professional Society. In the busy social work, he made a useful contribution to the country.
