圆锥内圈锻件的宽度尺寸

Width dimension of inner ring forgings of tapered roller bearings

为了保证锻件为大、小端面及挡边内侧都有可靠的车削留量,采取标注和测量套圈小端面至挡边内侧之距离的方法。文中从理论上论述了该方法的正确性,并介绍了各部位尺寸及偏差的设计计算方法。附图2幅。

In order to gua-rantee that the faces and inside of rib in bearing inner ring forgings possess reliable turning allowance, the method of dimensioning and measuring the distance from cone front face to inside of rib is adopted. The correctness of above method is discussed theoretically & the design calculation method of dimensions and deviations in every position is also introduced in this paper.
