Angular Contact (Spindle) bearings
Angular contact ball bearings (also known as spindle bearings) are bearings where the inner and/or outer ring shoulders are relieved Relieving the shoulder allows the ball complement to be changed to give greater load capacity (larger balls or a greater number of balls) and a stronger retainer allowing higher speed and better endurance
A novel model for high
Feb 04 2020In this study on the basis of the various contact angles and the hybrid theory a new mathematic model without the raceway control hypothesis is proposed for the analysis of ball bearing under the combined axial radial and moment loads Instead of the orthogonal decomposition method the triangular geometric theorem and vector diagram method have been used in the force analysis of local ball
