How to install the outer spherical bearing?

(1) The inner ring of the outer spherical bearing is tightly fitted to the shaft, and the outer ring is loosely fitted to the shell. The outer spherical bearing can be pressed onto the outer spherical bearing with a press, and then the shaft and the outer spherical bearing are put into the shell together. In the body, an assembly sleeve (copper or soft steel pipe) of soft metal material is placed on the end surface of the outer spherical bearing when pressing. The inner diameter of the assembly sleeve should be slightly larger than the diameter of the journal, and the outer diameter should be smaller than the rib diameter of the inner diameter of the outer spherical bearing to avoid pressing on the cage. When installing a large number of bearings, a handle can be added to the sleeve.

     When installing the outer spherical bearing, make the center line of the outer spherical bearing hole coincide with the shaft. The skew of the outer spherical bearing relative to the shaft is not only difficult to install, but also causes indentation, bending of the journal and even fracture of the inner ring of the outer spherical bearing.

     Where a press is lacking or cannot be used, the outer spherical bearing can be installed with an assembly sleeve and a small hammer. The hammering force should be evenly transmitted to the entire circumference of the end face of the outer spherical bearing ring, so the hammered end face of the assembly sleeve should be made into a spherical shape.

2) The outer ring of the outer spherical bearing is tightly fitted with the housing hole, and the inner ring is loosely fitted with the shaft. The outer spherical bearing can be pressed into the housing first. At this time, the outer diameter of the supporting pipe should be slightly smaller than that of the housing hole. diameter.

    (3) The inner ring of the outer spherical bearing and the shaft, the outer ring and the housing hole are tightly fitted, and the end face of the assembly sleeve should be made into a ring that can simultaneously compress the end faces of the inner and outer rings of the outer spherical bearing, or use a disc and the assembly Matching pipe, so that the pressure is transmitted to the inner and outer rings at the same time, and the outer spherical bearing is pressed into the shaft and the housing. This installation method is especially suitable for the installation of self-aligning radial spherical outer spherical bearings.

    (4) Heating installation, the force required to install the outer spherical bearing is related to the size of the outer spherical bearing and the size of the fit interference. For medium and large outer spherical bearings with large interference, the method of hot loading is commonly used. Put the outer spherical bearing or the separable outer spherical bearing ring into the oil tank or a special heater and heat it evenly to 80~100°C (should not exceed 100°C) before shrink fitting.

    Shrink-fitting spherical bearings requires skilled operating skills. When the outer spherical bearing is taken out from the heating oil tank or the heater, immediately wipe off the oil stains and attachments on the surface of the outer spherical bearing with a clean cloth (not cotton yarn), and then place it in front of the mating surface. Push the outer spherical bearing into position against the shaft shoulder. During the cooling process, it should be tightened all the time, or use a small hammer to tap the outer spherical bearing through the assembly sleeve to make it tight. When installing, the outer spherical bearing should be rotated slightly to prevent the installation from being tilted or stuck.

    When the outer ring of the outer spherical bearing and the housing hole are tightly fitted, the outer spherical bearing can also be installed after heating the housing. Especially when the outer spherical bearing seat made of light metal is tightly fitted, the mating surface may be damaged due to the pressing of the outer ring of the outer spherical bearing. At this time, the outer spherical bearing seat should be heated.
