Abstract

The invention discloses a floating oil seal which comprises a side cover seal, a sealing ring and an oil return hole. The side cover seal is of a floating type, a groove is formed in the sealing ring, a spring is fixedly arranged on the outer circle of the sealing ring, and the spring enables the sealing ring to be fixed between a casting side cover groove and a spindle. According to the floating oil seal, the requirement for precision of manufacturing and mounting is reduced, lubricating oil is prevented from seeping out along the spindle, workloads are reduced, mounting precision is increased, manufacturing and mounting errors are effectively reduced, and on-site working efficiency is improved.

Description

A kind of floatation type oil-seal
Technical field
Patent of the present invention relates to centrifugal vacuum machine technical field, is specifically related to a kind of floatation type oil-seal.
Background technique
Due to the existence of blower fan machining error and alignment error, blower fan main shaft and bearing support side cover axis hole can not be accomplished absolute concentric; Rear side cover axis hole and main shaft radial clearance circumference are installed respectively to inconsistent, scene needs spended time to regulate, therefore can be more complicated for on-the-spot installation, and be not easy to install for the person of lacking experience and adjust.
Summary of the invention
The object of invention: the object of the invention is, in order to make up the deficiencies in the prior art, provides a kind of floatation type oil-seal of increasing work efficiency.
The technical solution used in the present invention: a kind of floatation type oil-seal, comprise side cover sealing, seal ring and spill port, described side cover is sealed into floating type, on described seal ring, has groove, described seal ring outer ring is fixed with spring, and described spring is fixed on seal ring between foundry goods side cover groove and main shaft.
As optimization, described seal ring adopts rim of the mouth pattern between Hough.
Beneficial effect: the invention provides a kind of floatation type oil-seal, reduce and make and the required precision of installing, prevent that lubricant oil from oozing out along main shaft, reduce workload, increase installation precision, effectively make up and make and the error of installing, improve work on the spot efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of seal ring.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is described in detail:
A kind of floatation type oil-seal, comprises side cover sealing 1, seal ring 2 and spill port 3, and side cover sealing 1 is floating type, on seal ring 2, there is groove, seal ring 2 outer rings are fixed with spring 4, and spring 4 is fixed on seal ring 2 between foundry goods side cover groove and main shaft, and seal ring 2 adopts rim of the mouth pattern between Hough; Side cover sealing 1 adopts the graphite material with self-lubricating property, relies on spring 4 to hold main shaft tightly, can play the effect that prevents that lubricant oil from oozing out along main shaft.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
