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, open without sealing structure refers to the bearing, seal type deep groove ball into dust seal and oil seal. 

Single row deep groove ball bearing type code is 6, double row deep groove ball bearings, code-named 4. Its structure is simple, easy to use, is the most common production, the most widely used type of bearings.

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.

Deep groove ball bearing structure is simple, compared with the other type is easy to achieve high manufacturing accuracy, so easy to into a series of mass production, the manufacturing cost is low, is very popular use. Deep groove ball bearings in addition to the basic, along with a variety of variant structure, such as: deep groove ball bearing with dust cover, deep groove ball bearings with rubber sealing ring, a locking groove deep groove ball bearing, has the ball gap big load capacity of deep groove ball bearing, double row deep groove ball bearings.

Deep groove ball bearing installation method

1. Force 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, cushion the assembling casing made of a soft metal material (copper or mild steel), 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 hole first, then assembling casing diameter should be slightly less than the diameter of a hole. If the bearing ring and shaft and hole is a tight fit, install indoor ring and outer ring to pressure into the shaft and hole, at the same time assembling casing structure should be able to at the same time, so the bearing inner ring and outer ring end face.


2. Heating cooperates: the bearing or bearing by heating, the use of thermal expansion will fit into a loose fit method of installation. Installation method is a kind of common and energy saving. This method is suitable for interference quantity larger the installation of the bearing, the bearing before hot charging type or separable bearing ring into the fuel tank even heat 80-100 ℃, and then loaded on the shaft, as soon as possible out of the oil to prevent inner ring after cooling end face and the shoulder joint is not tight, to axial bearing cooling can then tighten. Bearing outer ring and light metal bearing seat tight fit, by heating the hot charging method of the bearing, can avoid the mating surface scratch. Heating tank with bearing and should be at a certain distance from the bottom of a mesh, or hanging hooks in the bearings, bearing on the bottom, in case of heavy impurities into the bearing or uneven heating, fuel tank must have a thermometer, strictly control the oil temperature shall not exceed 100 ℃, in order to prevent the tempering effect, reduce the hardness of the ring.
