Installation method:

 

 

 

One, pressing matching method:

 

 

 

1. When the bearing inner ring is closely matched with the shaft, and the outer ring is loosely matched with the bearing seat hole, the bearing can be pressed on the shaft first, and then the shaft and the bearing are loaded into the bearing seat hole together. When pressing, a soft metal assembly sleeve (copper or mild steel) is padded on the end face of the bearing inner ring.

 

 

 

2. When the bearing outer ring is closely matched with the bearing seat hole, and the inner ring is loosely matched with the shaft, the bearing is 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. If the bearing ring is closely matched with the shaft and the seat hole, the inner ring and the outer ring should be pressed into the shaft and the seat hole at the same time during installation, and the structure of the assembly sleeve should be able to press the end face of the inner and outer ring of the bearing at the same time.

 

 

 

Two, heating method:

 

 

 

By heating the bearing or bearing seat, the use of thermal expansion to change the tight fit into loose fit installation method, is a common and labor-saving installation method. This method is suitable for the installation of bearings with large interference. Before hot loading, the rings of bearings or separable bearings are put into the oil tank and heated evenly at 80-100℃, and then removed from the oil and installed on the shaft as soon as possible. In order to prevent the inner ring end face and the shaft shoulder from failing to fit tightly after cooling, the bearings can be tightened axial after cooling. This method can avoid abrasion on the mating surface.

 

 

 

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, to prevent impurities from entering the bearing inner or uneven heating, fuel tank in the thermometer, strictly control the oil temperature shall not exceed 100 ℃, in order to prevent the tempering effect, reduce the hardness of the ring.

 

 

 

Due to the high manufacturing accuracy of deep groove ball bearings, improper installation method will not only cause damage to deep groove ball bearings, but also reduce the service life. So in the installation is not careless, according to the correct installation steps to install, to ensure the normal operation of deep groove ball bearings.
