一种高速减速器用轴端密封试验装置

Shaft-end seal test device for high-speed decelerator

Abstract

The invention relates to a shaft-end seal test device for a high-speed decelerator. The device comprises a main shaft which is connected with a high-speed motor to form a drive end and is arranged in a horizontal direction, and two sets of shaft-end seals disposed on a sleeve of the main shaft. The periphery of the main shaft is provided with an annular sealed cavity which is disposed on the pedestal and is located between the two shaft-end seals. The main shaft is also provided with a bearing located in the sealed cavity. The peripheral surfaces of the shaft-end seals are sleeved by adjustment flanges. One end, far from the sealed cavity, of each shaft-end seal is provided with a lubricating oil leakage receiving disc. The device also comprises an adjustment mechanism which adjusts the flanges to move in the axial direction of the main shaft so as to simulate the radial jump of the shaft-end seals. The device can achieve a lubricating mode needed by the bearing in the sealed cavity, carries out the performance testing of the shaft-end seals at the same time in the lubricating mode, and improves the testing efficiency of the shaft-end seals. In addition, the device also can simulate the radial jump of the shaft-end seals.
本发明涉及一种高速减速器用轴端密封试验装置。本发明包括与高速电机连接构成驱动端且沿水平方向布置的主轴以及安装在主轴轴套上的两套轴端密封,所述主轴周向上设有安装在底座上且位于两组所述轴端密封之间的环状密封腔体,所述主轴上还设有位于所述密封腔体内的轴承,所述轴端密封周面上套设有调整法兰,所述轴端密封远离所述密封腔体的一端设有润滑油接漏盘,该装置还包括将所述调整法兰沿所述主轴径向进行移动以模拟所述轴端密封径向跳动的调整机构。本发明可以在所述密封腔体内实现轴承所需的润滑方式,并在相应的润滑方式下同时对两套轴端密封进行性能试验,提高了轴端密封的试验效率,另外本发明还可以模拟所述轴端密封的径向跳动试验。
