In recent years, Aerospace Seiko has developed from a single fastener product to four major categories of fasteners, bearings, rubber parts and anchors. Among them, the bearing is the first domestic innovative design product for aerospace body bearing positioning design, using German advanced manufacturing expertise and aerospace body supporting, complete range of products. Through the business model innovation of the international technical cooperation platform, Aerospace Seiko has acquired the current German aviation bearing manufacturing process and nearly 200 European and American aviation bearing technical standards in recent years. The high starting point, high standard development and high quality propulsion are the domestic production and development of the company's aviation bearings. Provide a good technical foundation.
On November 24th, 2016, the two typical specifications of self-lubricating joint bearings, rod end double row self-aligning ball bearings and single-row ball bearings with flanges successfully developed by Aerospace Seiko passed the typical air bearing localization technical review meeting. The meeting review team listened to the project summary report compiled by Aerospace Seiko and the third-party appraisal test conformity report, reviewed the relevant technical documents, and reviewed the production site. After discussion and inquiry, it is believed that the three types of aviation bearings developed are in full compliance with the corresponding European aviation bearings. The requirements of current product standards and technical specifications form a complete process document and quality control document, and it is agreed that the three types of bearings developed and produced by Aerospace Precision will pass the technical review.
The self-lubricating joint bearing, rod end double row self-aligning ball bearing and flanged single row ball bearing in this evaluation project are typical body bearings with wide application range and large number of uses (the body bearing is connected to all parts of the aircraft body). The key basic component is the joint of the fuselage structure of the aircraft. All movements of the aircraft body must be completed by the rotation or oscillation of the body bearing). The rod end double row self-aligning ball bearing and the flanged single row ball bearing are produced in China for the first time in accordance with the current European product standards and technical specifications, and have obtained the domestic authoritative third-party qualification test report, including the limit temperature test and sand dust. The test, seal tightness test, axial two-way stage load test and other identification test items are the first in China, which has opened the domestic first of these types of aviation ball bearings.
The Bearing Division completed all the research contents and technical indicators in the task book of the scientific research project, and passed the in-house and external third-party testing and testing. The project documents are complete, the data is detailed and reliable, the quality control is in place during the production and inspection process, and it meets the requirements of the company's quality management system. The Bearing Division broke through a series of technical difficulties in the project development process, forming 6 sets of product drawings, 9 standard technical documents, more than 10 processing technology documents, more than 100 tooling mold drawings, and accepted 3 invention patents and 3 copies. The scientific research results of the utility model patent (one authorized) have laid a good technical foundation for the further domestic production and production of the company's follow-up aerospace bearings.
