Abstract

Provided is a shaft end sealing structure, comprising a shaft, a flange, a washer, an o-shaped ring, a cover plate and a nut. The utility model is characterized in that the flange is splinedly jointed to the shaft, a circular groove is arranged at the end of the spline joint, the washer and the o-shaped ring are arranged in the circular groove, a flange end face is at the other end of the circular groove, the nut is threadedly connected to the shaft and the cover plate is fixed to the flange end face. By adopting the above structure, the utility model has advantages of preventing deformation of o-shaped ring, achieving good sealing effect and long service life.

Description

A kind of sealing structure of shaft end
Technical field
The utility model relates to a kind of sealing structure of shaft end that is applied to construction machinery gear box.
Background technique
At present, the construction machinery gear box sealing structure of shaft end is: 1, flange is connected with spline with axle, and an O shape ring recess is left in the end of connection; 2, an O shape circle is installed on O shape ring recess; 3, in the O shape circle outside cover plate is installed; 4, a nut that is connected with axle is installed in the cover plate outside.There is following shortcoming in this sealing configuration: because O shape circle is directly installed on the spline end face, O shape circle is easy to be got in the spline teeth groove, thereby causes that the distortion of O shape circle loses sealing effect.
Summary of the invention
The purpose of this utility model provides the sealing structure of shaft end of the distortion of a kind of O of preventing shape circle, good sealing effect, long service life.
The purpose of this utility model is achieved in that by flange, axle, O shape circle, cover plate, pad to be formed, flange is connected with spline with axle, spline connects annular groove of end design, a pad is installed earlier on the annular groove, an O shape circle is installed again, the other end of annular groove is an end face of flange, and nut is fixed on cover plate on the end face of flange by being threaded with axle.
Because the utility model adopts said structure, prevent the distortion of O shape circle, good sealing effect, long service life.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
1,2 flanges, 3 pads, 4O shape circle, 5 cover plates, 6 nuts among Fig. 1.
Embodiment
Embodiment: the utility model is made up of axle 1, flange 2, pad 3, O shape circle 4, the external splines of axle 1 is connected by spline with the internal spline of flange 2, the annular groove of end design that connects, in order to pad 3 and O shape circle 1 to be installed, pad 3 leans against on the spline end face, and O shape circle 4 leans against on the pad 3, O shape circle 4 just can not squeezed distortion by spline when compressing like this, pad 3 plays the effect that prevents 4 distortion of O shape circle, and O shape is enclosed 4 cross sections can not be subjected to spline injury, long service life.
Nut 6 is on the end face of flange 2 with axle 1 by the other end that cover plate 5 is fixed on annular groove that is threaded, cover plate 5 encloses 4 axial compression with pad 3 with O shape, O shape is enclosed 4 internal diameters and is leaned against on axle 1 the external diameter, O shape is enclosed on the internal diameter that 4 external diameters lean against flange 2, the fluid in spline left side can't pass through O shape circle 4 seepage to the right, good sealing effect.
