The rational arrangement of the main shaft rolling bearings of the Longmen Processing Center, the configuration form of the two inheritance shaft bearing, the configuration form of the two inheritance shaft bearings, including the main shaft
Selection, combination and arrangement of bearings. It is mainly based on the requirements of the main axis components in the aspects of speed, bearing capacity, stiffness, and accuracy of the designed parts.
The arrangement of the two main shaft rolling bearing used.
When confirming the two inheritance shaft bearing configuration forms, the following general principles should be followed:
The Longmen Processing Center adapts to the requirements of stiffness and bearing capacity to get the required stiffness and bearing capacity. When the radial load is large, the bearing can be selected
Setting form; small hours, configuration forms can be selected. In addition, double -row bearings are higher than single -row. Since the rigidity of the previous support can increase the rigidity of the main axis part
Degree, so the bearing that increases stiffness should be configured in the front support.
