Share two installation methods of deep groove ball bearing

Deep groove ball bearing also has a kind of name is single row centripetal ball bearing, which is mainly used to reduce rolling friction and make the machine roll up. Because the structure of deep groove ball bearing is simpler and it is easier to achieve higher manufacturing precision, it is convenient to produce in large quantities. Below are two installation methods introduced by the bearing manufacturer. Let's have a look at them together!

Installation method of deep groove ball bearing I: Press in fit

When the inner ring of bearing and the shaft are tightly matched, when the outer ring and bearing seat hole are loose, the bearing can be pressed and installed on the shaft by a press, and then the shaft and the bearing are installed in the bearing seat hole. When pressing, the assembly sleeve (copper or soft steel) made of soft metal material is padded on the end face of the bearing inner ring. When the outer ring of the bearing and the bearing seat hole are relatively loose, the inner ring and the shaft are relatively 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 and the shaft and the seat hole are tightly matched, the inner ring and outer ring of the installation shall be pressed into the shaft and the seat hole at the same time. The structure of the assembly sleeve shall be able to tighten the end face of the inner ring and outer ring of the bearing simultaneously.

Installation method of deep groove ball bearing II: heating fit

The method is a common and labor-saving installation method. This method is suitable for the installation of bearings with large interference. Before hot installation, put the bearing or the sleeve ring of separable bearing into the oil tank and heat 80-100 ℃ evenly, and then take out the oil and install it on the shaft as soon as possible, In order to prevent the end face and shoulder of inner ring from being tightly connected after cooling, the bearing can be tightened axially after cooling. When the outer ring of bearing is tightly matched with the light metal bearing seat, the hot installation method of heating bearing seat can avoid abrasion of the mating surface. When heating the bearing with oil tank, there should be a grid at a certain distance from the bottom of the box, or the bearing should be hung with a hook. The bearing cannot be placed on the bottom of the box to prevent the sinking impurities from entering the bearing or uneven heating. The oil tank must have a thermometer, and the oil temperature shall not exceed 100 ℃ strictly to prevent tempering effect and reduce the hardness of the collar.
