What is deep groove ball bearing
Deep groove ball bearings (GB/T 276-2003), formerly known as single-row centripetal ball bearings, are the most widely used rolling bearings. Its characteristics are small friction resistance, high speed, can be used to bear radial load or radial and axial simultaneous action of the combined load on the machinery, can also be used to bear axial load on the machinery.
Properties of deep groove ball bearings
Deep groove ball bearing is the most common type of rolling bearing. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a group of steel balls and a group of cages.
There are two types of deep groove ball bearings: single row and double row. Deep groove ball structure is also divided into sealed and open structure. Open type means that the bearing does not have a sealed structure.
The working principle of deep groove ball bearing
Deep groove ball bearing mainly bears radial load, also can bear radial load and axial load at the same time. When it bears only radial load, the contact Angle is zero. When deep groove ball bearing has large radial clearance, it has the performance of angular contact bearing and can withstand large axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is also very high.
Installation method for deep groove ball bearings
Deep groove ball bearings generally have two installation methods, respectively as follows:
1. Pressing fit: Bearing inner ring and shaft tight fit, outer ring and bearing hole is a loose fit, press the bearing to be pressed on the shaft are available, and then put the shaft together with the bearing load bearing hole, when pressed on the bearing inner ring end face, the assembling casing made of a soft metal materials, bearing outer ring and bearing hole tight fit, inner ring and the shaft is a loose fit, The bearing can be pressed into the bearing seat hole first, then the outer diameter of the assembly sleeve should be slightly less than the diameter of the seat hole.
2. Heating fit: by heating the bearing or bearing seat, the installation method of using thermal expansion to change the tight fit into the loose fit. It is a common and labor-saving installation method. This method is suitable for the installation of bearings with large interference amount. Before hot loading, put the rings of bearings or separable bearings into the oil tank for uniform heating of 80-100℃, and then take them out of the oil and install them on the shaft as soon as possible. In order to prevent the end face of the inner ring and the shaft shoulder from fitting tightly after cooling, the bearings can be tightened axially after cooling.
