Abstract
The utility model relates to an oil-leakage prevention shaft gland device consisting of an output shaft of a case and an oil seal box. An end surface of the case and the output shaft are coaxially provided with the oil seal box. A centrifugal impeller is fixed on the output shaft in the oil seal box. An oil scraping plate is tangent with the plane of the centrifugal impeller and fixed on the oil seal box. An oil return hole is arranged on a wall of the case in the oil seal box. The oil-leakage prevention shaft gland device has the advantages of reasonable design, simple structure and good sealing effect.
Description
Technical field
The utility model belongs to seal arrangement, particularly relates to a kind of anti-leakage of oil gland seal device.
Background technique
At present, shaft sealer is widely used in a plurality of industries such as production, processing, machine-building, as be applied in the machinery such as wind turbine equipment middle gear case, motor, but the problem of existing shaft sealer ubiquity leakage of oil, leakage of oil mainly concentrates on axle and casing joint, has badly influenced the normal operation of system.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of anti-leakage of oil gland seal device is provided.
Anti-leakage of oil gland seal device of the present utility model is that output shaft and the oil sealing box by casing constitutes.Be provided with the oil sealing box with the coaxial heart of output shaft on the end face of casing, be fixed with centrifugal impeller on the output shaft in the oil sealing box, have with the centrifugal impeller plane tangent and be fixed on oil scraping plate on the oil sealing box, on the wall of the casing in the oil sealing box spill port is arranged.
As further improvement of the utility model, on output shaft, has a slice centrifugal impeller at least at oil sealing box internal fixation.
As further improvement of the utility model, 1～3 impeller is arranged on output shaft.
As further improvement of the utility model, centrifugal impeller has two-sided tangent and be fixed on oil scraping plate on the oil sealing box.
Anti-leakage of oil gland seal device of the present utility model, reasonable in design, simple in structure, good sealing effect.
