The working principle of deep groove ball bearing characteristics and selection

Deep groove ball bearing characteristics and selection principle of source: bearing | last updated: - 2020 04 - 02 working principle of deep groove ball bearing deep groove ball bearing is one of the most common types of rolling bearing. Basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel ball and a set of cage. Deep groove ball bearing type has a single row and double row two kinds, deep groove ball structure is sealed and open two kinds of structure. Deep groove ball bearings mainly take radial load, also can bear radial load and axial load at the same time. When its only bear radial load, the contact Angle is zero. When deep groove ball bearings with larger radial clearance, with the performance of angular contact bearings, can withstand large axial load, deep groove ball bearing friction coefficient is small, the limit rotational speed is high. The characteristics of deep groove ball bearing and the selection of deep groove ball bearing is the most representative of the rolling bearing. Compared with other kinds of bearings of the same size, such bearing small friction coefficient, high limit speed, simple structure, low manufacture cost, high accuracy, no dimension and large size range and a lot of forms, often is the most widely used type of bearings. It mainly bear radial load, also can absorb a certain amount of axial load. When its only bear radial load, the contact Angle is zero. Deep groove ball bearings mounted on a shaft, within the scope of the axial clearance of bearing, can limit shaft or the shell axial displacement in two directions, so can in two-way axial positioning. When deep groove ball bearings with larger radial clearance, with the performance of angular contact bearings, can withstand a large axial load. Under axial load large high-speed operation conditions, deep groove ball bearings have more advantages than thrust ball bearing. In addition, this class also has a certain bearing capacity, when relative to the shell hole 2 ~ 10 ', can still work normally, but has a definite effect on bearing life.
