1. How to limit the position of the shaft, including radial and axial position should be considered first. Qingdao Ruijing mechanical and electrical company vigorously exploit the market the product sales rose more than the shaft of the general with double supporting structure, the axis of the radial position by two supporting common limit, each bearing place is due on the radial orientation effect to the heart or Angle contact bearings. Axial position by two supporting the limit a direction of the axial displacement can also be made by a supporting limit the two directions of the axial displacement, be in usually, different axial localization way can make the different running accuracy. Therefore, supporting structure design should be based on the operation of the shaft precision and working conditions, choose axial orientation concrete plan.

2. At the same time bear radial load and axial load, the joint venture company in China manufacturing, selling auto bearing an agreement about supporting often uses angle contact bearings and tapered roller bearing installed in pairs. Angle contact bearings are installed in three arrangement. Two bearing outer ring width end relative installation says installation way back. Two supporting force in supporting point fall outside the span. This arrangement for supporting the span, shaft when cantilever good rigidity, shaft when heated elongation is inner and outer withdraws trend, thus axis will not jammed, so use more widely. But if the preloaded installation, is in the shaft when heated preloaded volume will be reduced. Two bearing outer ring narrow end relative installation says installation way face to face. Two supporting force in supporting point fall within the span. This arrangement of simple structure, installation, debugging are more convenient and more extensive reason is used, mainly used for short axis and the temperature rise is not high occasions, spindle bearing accuracy is high, the special structure, particularly difficult processed but take note must have spare clearance. Axial clearance also shoulds not be too big, will reduce shaft running accuracy. When the axial load is bigger, need more overwhelmed and bearing, often uses bearing outer ring width, narrow face relatively installation way of the series. The bearing force all fell on bearing the point on the same side of it is called homonymous arrangement and says the series. Which used the arrangement of the note that the structure and manufacturing to ensure that every bearing can as far as possible even loads.

3. The machine running unattended, national and global bearing market, the market share of the higher general spindle or higher temperature than the drive shaft parts of the adjacent temperature, thus axis will heat elongation. In order to keep the flexible rotation axis, in supporting structure design, and to meet the requirements of the axial location accuracy, while also consider the requirements of free expansion shaft is heated. Axial orientation and axial telescopic way is corresponding.

 
4. Adjust bearing clearance is to control the shaft running accuracy. Rachel fine bearing company efficiency of reducing the shaft axial position adjustment is in order to meet the special requirements of some meshing transmission. For example: in the worm transmission, must fall in worm gear and worm axis in the middle of the plane within in order to ensure its mesh properly, and requirements of rotor wheel can adjust its position in axial. In the bevel gear transmission, two of the taper cone vertex bevel gear section must be coincidence, so it requires two bevel gear shaft can axial adjustment.
