In the appraisal meeting of the ZJ112 type 10000/sub-coil unit and the ZB47 type 550-pack/sub-packaging unit, which were organized by the Department of Science and Education of the State Tobacco Monopoly Bureau in Wuhan, the prototypes of both projects passed the appraisal of the expert group.
The appraisal report presented by the expert group gave high praise to the two prototypes. The appraisal committee unanimously agreed that the development of the ZJ112 type coiling unit prototype has reached the requirements of the special science and technology contract, and its main technical and economic indicators have reached the advanced level of the international similar products. Level, the development of the prototype is successful, agreed to pass the identification, it is recommended to enter small batch production, and promoted in the Chinese tobacco industry. Regarding the prototype of ZB47 packaging unit, the appraisal committee unanimously agreed that the prototype of the prototype was successful. The overall technical and performance indicators of the project reached the international advanced level in similar products, filling the blank of domestic cigarette packaging machinery of 400 packs/min or more.
It is understood that ZJ112 type 10000/min coil unit and ZB47 type 550 pack/package unit project are the manufacturing technology of PROTOS90E coiling unit and GDXC packaging unit introduced by China National Tobacco Corporation from Germany Hongni Company and Italy GD Company. Led by China Tobacco Machinery Group Co., Ltd., China Tobacco Machinery Technology Center Co., Ltd., Changde Tobacco Machinery Co., Ltd., Shanghai Tobacco Machinery Co., Ltd. and other units jointly undertaken research and development. These two projects were included in the tobacco industry's major technical equipment technology development project plan during the 10th Five-Year Plan period.
In the process of project development, the research unit and the trial production unit have contributed to the development of China's hood business with a scientific attitude and rigorous style. The successful development of these two projects has narrowed the gap between China's tobacco machinery research and development, manufacturing level and foreign advanced level, and is a new milestone in the development of China's tobacco machinery technology.
During the appraisal meeting, the signing ceremony for the acceptance of the protos90E technology transfer project of China National Tobacco Corporation and Germany Hauni Company was arranged, and the discussion on the establishment of a new type of cooperation relationship between China Tobacco Machinery Group Co., Ltd. and China Tobacco Industrial Co., Ltd. and cigarette industry enterprises was organized. The meeting and the new product information release meeting of the hood.
Li Keming, deputy director of the National Tobacco Monopoly Bureau, pointed out in the summary speech of the appraisal meeting that the identification of the ZJ112 type coiling unit and the ZB47 type packaging unit prototype marked a historic breakthrough in the digestion and absorption of domestic coiled packets and entered a new The stage of development. At the same time, it is proposed that cigarette industrial enterprises and hood manufacturing enterprises should work closely together to form a joint force, focus on promoting independent innovation, and accelerate the transformation of economic growth mode.
Angular contact ball bearings mainly bear large unidirectional axial load. The greater the contact angle, the greater the load bearing capacity. The material of cage is steel plate, brass or engineering plastics. The forming method is stamping or turning. It is selected according to the bearing form or using condition. Others include combined angular contact ball bearings, double row angular contact ball bearings and four-point contact ball bearings.
Angular contact bearings are able to support radial load and axial load. As single row angular contact ball bearings can only support axial load in single direction, matched bearing mounting is often adopted to them as matched parts of bearings, preload for them is more convenient. Retainers are made of brass, synthetic resins or others subject according to individual bearing features and application conditions.
