锤式破碎机转子轴承公差配合的分析与选择

<title>alysis and Selection of Tolerance and Fit of Rotor Bearing in Hammer Crusher

指出由于PC1010锤式破碎机转子轴承公差配合选择不当,导致轴承早期失效。提出以轴承允许的最高工作温度计算内圈和外圈的热膨胀量,然后据此选择合适的公差配合。

<abstract>e tolerance and fit of rotor hearing in PC1010 hammer crusher is unsuitable, Which result in its early failure.The author put forward that heat expansion of hearing inner race and outer ring arc calculated out bused on the highest allowable service temperature of hearing. In view of the above, the suitable tolerance and fit are selected.
