Mounting dimensional accuracy of male spherical housing

Pay attention to the installation reaction force. For example, there are pressure pits with spacing on the raceway, indicating that the load has exceeded the elastic limit of the raw material. This is caused by static data truncation or severe impact (such as hitting the outer spherical bearing seat with a small axe hammer during installation). The installation method of the outer spherical bearing seat is to react the force only to the ring to be riveted.

Pay attention to the installation orientation of the thrust spherical roller housing. The outer spherical bearing housing has a duck-egg annular contact area and is only responsible for radial thrust on one side. When the outer spherical bearing seat is installed artificially in the opposite direction, since the bearing steel ball is on the edge of the raceway, a groove-shaped wear band will germinate on the bearing surface. Because of these, pay attention to the exact installation orientation when installing.

Thrust spherical roller housing specification accuracy (new items related to shaft and housing installation):

1. Inner diameter. Diameter. Allowable error of the total width of the outer spherical bearing seat and the total width of the installation;

2. The allowable error of the inner and outer circle diameters of the outer spherical bearing seat of the roller group;

3. The allowable boundary value of the rounded outer spherical bearing seat specification;

4. The allowable variation of the overall width of the outer spherical bearing seat.
