Abstract
The utility model relates to a novel shaft sealing structure, which comprises a shaft, a shaft sleeve, a bearing, a bearing gland and a bearing seat, and is characterized in that the surface of a inner ring hole of bearing gland is provided with a labyrinth sealing ring, the inner end surface of the inner ring hole is processed with a bevel angle, the outer side surface of the shaft sleeve is provided with a right angle convex edge, and the right angle convex edge corresponds to the bevel angle on the inner end surface of the inner ring hole of the bearing gland. The novel shaft sealing structure has the advantages that oil is prevented from leaking through using the function of throwing oil of the shaft sleeve.
Description
Technical field
The utility model relates to a kind of new-type shaft seal structure.
Background technique
The form of the lubricated employing labyrinth seal lubricant oil of axle system is carried out at present, but common labyrinth seal structure exists the phenomenon of leakage of oil, needs the lubricant oil of often annotating for this reason, causes the waste of lubricant oil on the one hand, has also influenced environmental hygiene in addition.Therefore demand inventing a kind of novel shaft seal structure urgently, to address the above problem.
Summary of the invention
The purpose of this utility model is the problem that common labyrinth seal exists leakage of oil in the solution prior art, and a kind of new-type shaft seal structure is provided.The utility model designs a kind of new-type shaft seal structure, comprise axle, axle sleeve, bearing, bearing gland, bearing support, it is characterized in that: on bearing gland inner ring hole face, offer labyrinth seal, on the interior edge face of inner ring hole, be processed with the oblique angle, one right angle chimb is arranged on the outer side surface of axle sleeve, and the oblique angle on the interior edge face of right angle chimb and bearing gland inner ring hole is corresponding.The utility model has the advantages that utilizing axle sleeve to have gets rid of oily effect, prevents leakage of oil.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
Comprise axle 1, axle sleeve 2, bearing 3, bearing gland 4, bearing support 5 among the figure, it is characterized in that: on 6 of bearing gland 4 inner ring holes, offer labyrinth seal 7, on the interior edge face of inner ring hole 6, be processed with the oblique angle, one right angle chimb 8 is arranged on the outer side surface of axle sleeve 2, and the oblique angle on the interior edge face of right angle chimb 8 and bearing gland 4 inner ring holes 6 is corresponding.
According to the mobile principle of fluid in the rotary component, promptly when fluid attached to rotary component on the time, and do not reach the rotating speed of the separation of flow, its moving direction is to flow to the big direction of diametric(al), shown in figure three, even the trend that the direction that the also oriented diametric(al) of the separation of flow is big flows, the effect of the right angle chimb 8 on the axle sleeve 2 that is subjected to when then the lubricant oil that outbound flows from bearing support 5 inside runs into axle sleeve 2 rotating with axle is thrown away, gets back to bearing support 5 inside.
Claims (1)
1. new-type shaft seal structure, comprise axle, axle sleeve, bearing, bearing gland, bearing support, it is characterized in that: on bearing gland inner ring hole face, offer labyrinth seal, on the interior edge face of inner ring hole, be processed with the oblique angle, one right angle chimb is arranged on the outer side surface of axle sleeve, and the oblique angle on the interior edge face of right angle chimb and bearing gland inner ring hole is corresponding.
