Abstract

The invention discloses a shaft oil seal with oil returning directly, and a machine tool. The shaft oil seal comprises a shaft oil seal component, an annular oil chamber and an oil return port, wherein the annular oil chamber is connected with the oil return port; one end of the oil return port is connected with a box; and a small port is formed at the part, connected with the oil return port, of the box. With the adoption of the shaft oil seal, the oil leakage is precluded, a good oil saving effect is exerted, the number of spare parts is reduced, the assembly efficiency is improved, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of an oil seal, in particular to a shaft oil seal and a machine tool that directly returns oil. Background technique [0002] Generally, the oil return method of the shaft oil seal of the gearbox is to return the oil through the oil pipeline outside the box. figure 1 It is an oil seal structure for the compressor shaft. The waste oil in the oil seal flows into the box through the oil return pipe assembly. However, this structure has several major defects. One is the problem of oil leakage, and the other is the addition of unnecessary pipe joints , pipelines and other components reduce assembly efficiency and increase costs. Contents of the invention [0003] In view of this, the present invention proposes a direct oil return shaft oil seal and a machine tool to solve the above-mentioned problems of oil leakage, low assembly efficiency and high cost. [0004] In order to achieve the above object, technica...
