Two methods of install ball cage bearing.

The installation of the ball cage bearing should be based on the structure of the ball cage bearing, the size and the matching properties of the deep groove ball bearing components. The pressure should be directly applied to the end face of the tightly fitted ring, and no pressure can be transmitted through the rolling elements. Deep groove ball bearings Installation generally adopts the following methods:
　　A.
Press fit
When the inner ring of the ball cage bearing is tightly fitted with the shaft, and the outer ring is loosely fitted with the deep groove ball bearing seat hole, the deep groove ball bearing can be press-fitted on the shaft with a press, and then the shaft and the deep groove ball bearing can be assembled together Put it into the seat hole of the ball cage bearing, and pad an assembly sleeve made of soft metal material (copper or mild steel) on the end face of the inner ring of the deep groove ball bearing during press-fitting. The inner diameter of the assembly sleeve should be slightly larger than the journal diameter. The outer diameter should be slightly smaller than the inner ring rib of the deep groove ball bearing to avoid pressing on the cage.

The outer ring of the ball cage bearing is tightly fitted with the hole of the deep groove ball bearing seat. When the inner ring and the shaft are loosely fitted, the deep groove ball bearing can be pressed into the hole of the deep groove ball bearing first. At this time, the outer diameter of the assembly sleeve should be Slightly smaller than the diameter of the seat hole.
When the ball cage bearing ring is tightly fitted with the shaft and the seat hole, the inner ring and outer ring must be installed into the shaft and the seat hole at the same time. The structure of the assembly sleeve should be able to tighten the inner ring and the outer ring of the deep groove ball bearing at the same time. The end face of the circle.

　　B. Heating coordination
　　 By heating the ball cage bearing or deep groove ball bearing seat, the installation method that uses thermal expansion to transform the tight fit into the loose fit is a common and labor-saving installation method. This method is suitable for the installation of ball cage bearing with large interference.
Put the ring of the deep groove ball bearing or separable deep groove ball bearing into the oil tank and heat it evenly at 80-100℃ before hot assembling, 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 from cooling. Should not fit tightly, the ball cage bearing can be tightened axially after cooling down.

When the outer ring of the ball cage bearing is tightly fitted with the light metal deep groove ball bearing seat, the hot mounting method of heating the deep groove ball bearing seat can be used to avoid scratches on the mating surface. When heating deep groove ball bearings with an oil tank, there should be a grid at a certain distance from the bottom of the box, or the deep groove ball bearings should be hung with a hook. The deep groove ball bearings cannot be placed on the bottom of the box to prevent sinking impurities from entering the deep groove ball bearings. Or uneven heating, there must be a thermometer in the oil tank, and the oil temperature must be strictly controlled not to exceed 100°C to prevent the occurrence of tempering effects and reduce the hardness of the ferrule.
