主减差速器轴承调整装置制造方法及图纸

本实用新型专利技术涉及一种主减差速器轴承调整装置，它包括主减差速器壳体（３）、主减齿轮（１）及差速齿轮轴（２），差速齿轮轴（２）通过两端的轴承（７）与壳体（３）连接，其特征在于：壳体（３）两端设有带有台阶的轴承孔（５），轴承孔（５）中设有调整垫片（４）与轴承（７）配合。本实用新型专利技术的优点在于：调整垫片厚度由计算机根据检测到的差速器轴承座实际宽度尺寸、差速器实际宽度尺寸，再结合被齿的安装距由计算机模拟差速器总成安装获得，这就保证了差速器左右轴承预紧力的相同并且使主、从动齿轮啮合位置在其实际安装距上，提高了齿轮和轴承的寿命及运转稳定性，降低了齿轮的啮合噪声。（*该技术在2018年保护过期，可自由使用*）

Main reduction differential bearing adjusting device

The utility model relates to a main reducer differential bearing adjusting device, which comprises the main reducer differential shell (3), (1) the main reducing gear and differential gear shaft (2), differential gear shaft (2) through both ends of the bearing (7) and the shell (3) is characterized in that the shell (3) are arranged at both ends of the bearing hole with steps (5), (5) is arranged in a bearing hole and bearing shim (4) and (7). The utility model has the advantages of adjusting shim thickness by the computer according to the detected differential bearing seat width, the actual differential actual width size, combined with the tooth mounting distance by computer simulation of differential assembly installation, which ensures that the differential about bearing preload and the same drive gear and the driven gear meshing position in the actual installation distance, improve the service life and the operation stability of gears and bearings, reducing the noise of gear meshing.
