Application of Widely Used Deep Groove Ball Bearing

Application of Widely Used Deep Groove Ball Bearing

Widely used deep groove ball bearings can be used in gearboxes, instruments, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo-yo, etc.

Installation method
Deep groove ball bearing installation method 1: Press fit: When the inner ring of the bearing and the shaft are tightly fitted, and the outer ring and the bearing seat hole are loosely fitted, the bearing can be press-fitted on the shaft first, and then the shaft together with the bearing. Put them into the hole of the bearing seat together. When press-fitting, on the end face of the inner ring of the bearing, pad an assembly sleeve (copper or mild steel) made of soft metal material. The outer ring of the bearing is tightly fitted with the hole of the bearing seat, and the inner ring and the shaft are When the fit is loose, the bearing can be pressed into the bearing seat hole first. At this time, the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole. If the bearing ring is tightly fitted with the shaft and the seat hole, install the inner ring and the seat hole. The outer ring should be pressed into the shaft and the seat hole at the same time, and the structure of the assembly sleeve should be able to press the end faces of the inner ring and the outer ring of the bearing at the same time.

Deep groove ball bearing installation method 2: Heating fit: By heating the bearing or bearing seat, the tight fit is transformed into a loose fit by thermal expansion. It is a common and labor-saving installation method. This method is suitable for large interference. For the installation of the bearing, put the bearing or separable bearing ring into the oil tank and heat it evenly at 80-100 ℃ before hot-loading, and then take it out of the oil and install it on the shaft as soon as possible. In order to prevent the end face of the inner ring and the shaft shoulder after cooling If the fit is not tight, the bearing can be axially tightened again after cooling. When the outer ring of the bearing is tightly fitted with the light metal bearing seat, the hot-fitting method of heating the bearing seat can be used to avoid the mating surface from being scratched. When heating the bearing with the oil tank, there should be a mesh grid at a certain distance from the bottom of the box, or hang the bearing with a hook. The bearing should not be placed on the bottom of the box to prevent heavy impurities from entering the bearing or uneven heating. There must be a thermometer in the oil tank. Strictly control the oil temperature not to exceed 100 ℃ to prevent the tempering effect and reduce the hardness of the ferrule.
