The purpose and installation method of deep groove ball bearings
Deep groove ball bearings can be used in gearboxes, instruments, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, roller skates, yo yo, and more

Installation method
Installation method one for deep groove ball bearings: Press fit: The inner ring of the bearing is tightly fitted with the shaft, and when the outer ring is loosely fitted with the bearing seat hole, a press can be used to press the bearing onto the shaft first, and then the shaft and bearing can be installed into the bearing seat hole together. When pressing, a soft metal material assembly sleeve (copper or soft steel) should be placed on the end face of the bearing inner ring. The outer ring of the bearing is tightly fitted with the bearing seat hole. When the inner ring is loosely fitted with the shaft, 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 seat hole, both the inner and outer rings of the installation chamber should be pressed into the shaft and seat hole at the same time, and the structure of the assembly sleeve should be able to simultaneously press the end faces of the bearing inner and outer rings.
Installation method 2 for deep groove ball bearings: Heating fit: By heating the bearing or bearing seat, the tight fit is transformed into a loose fit through thermal expansion It is a commonly used and labor-saving installation method This method is suitable for the installation of bearings with large interference fit. Before hot installation, place the bearing or separable bearing ring into the oil tank and heat it evenly at 80-100 ℃. Then remove it from the oil and install it on the shaft as soon as possible. To prevent the inner ring end face from not fitting tightly to the shaft shoulder after cooling, the bearing can be tightened axially after cooling When the outer ring of the bearing is tightly matched with the light metal bearing seat, the hot installation method of heating the bearing seat can avoid scratching the mating surface. When heating bearings with an oil tank, there should be a mesh grid at a certain distance from the bottom of the tank, or the bearing should be hung with a hook. The bearing cannot be placed on the bottom of the tank to prevent impurities from entering the bearing or uneven heating. There must be a thermometer in the oil tank, and the oil temperature must be strictly controlled not to exceed 100 ℃ to prevent tempering effect and reduce the hardness of the ring.
