Deep groove ball bearing industry development prospects

Source: Time:2019-05-16 15:23:02 frequency:

Bearing equipment manufacturing industry is important, the key infrastructure components, directly determine the key equipment and a host of product performance, quality and reliability, as the equipment manufacturing "heart" part, but a representative of the national scientific and technological strength high-precision products. After years of development, China's bearing industry has formed a considerable scale, 2015, China's bearing production is expected to more than 28 billion units, main business revenue is expected to reach 210 billion yuan, will become the world's largest bearing production and sales base. However, China's bearing industry big but not strong, compared with the world bearing industrial powers, China's bearing industry, there are still some gaps.
Deep groove ball bearings and other types of bearings of the same size as compared to the minimum friction loss, high speed limit, should not be used in the case of high speed thrust ball bearings, these bearings can be used to bear pure axial load. Should improve its manufacturing precision, and the use of bakelite, bronze, aluminum and other materials hard solid cage, the speed can be increased. In terms of structure, each ring of deep groove ball bearings have a cross-section of approximately one-third of the circumference of the ball of the continuous groove type raceway. Its main function is an additional radial load to bear, and to one of the load bearing capacity of the support. At present, China bearing demand more optimistic, such as cars, cars, motorcycles, clicks, household appliances and office automation machinery hosting industry, water, gas and currently ending Shanghai World Expo, we have confirmed our complete set of construction equipment engineering equipment and have a greater demand.
From manufacturing skills level, China's production of deep groove ball bearings precision, performance, longevity and reliability of the hosting industry sector has not yet reached the matching requirements. In the production process and configuration levels, most of the old state-owned enterprises, especially enterprises, as the main production is still the traditional configuration, a lower rate of car CNC machining and grinding automation level; to deep groove ball bearing life and reliability to shut tight ancestors punishment heat treatment technology and equipment research problems of many skills, failed to achieve a breakthrough; deep groove ball bearings groups fabrication process due to the low processing ability index evacuation of large size, uniformity, poor product quality inherent instability. In the deep groove ball bearing material, the result of secret technology, deep groove ball bearing steel deep groove ball bearings of high-end domestic sector is still dependent on imports, deep groove ball bearing steel research and development of new steel grades, steel processing and the process of lubrication, cooling, washing coherent development of key skills, still can not adapt to the deep groove ball bearings to improve product quality and temperature requirements.
Radial runout of assembled bearing outer ring when the outer ring Kea different angular positions, the maximum and minimum radial diameter surface of the inner ring relative to the difference between a fixed distance. In the angular position of the point at or near both sides of the rolling elements should be on the inner and outer ring raceway or the inner wall surface of the contact that is in the back of the bearing parts in their normal relative positions. As China bearing product quality continues to improve, the emergence of a number of products bearing generate business, its product quality is quite well-known international brands, will continue to expand the scale of exports. Countries in recent years has been to increase energy conservation efforts, advocated the building of a conservation-oriented society, must accelerate the transformation of traditional industries and energy-saving process, while promoting the rapid development of new energy industry, will bring greater opportunities for the bearing industry.
