Abstract
The utility model relates to the mechanical field, in particular to a sealing structure of a drive shaft end. The technical scheme includes that the sealing structure of the drive shaft end comprises a shaft casing, the drive shaft, a sealing framework and a sealing sleeve, wherein the a bearing is arranged in the shaft casing, the drive shaft is sleeved on the bearing, the sealing framework is sleeved outside the drive shaft and in an interference connection with the inner wall of the shaft casing, the sealing sleeve is arranged between the sealing framework and the drive shaft, a first groove is arranged on the wall where the sealing sleeve contacts with the drive shaft, a first seal ring is embedded in the first groove, a slope surface facing the drive shaft is arranged at one end close to the bearing on the sealing sleeve, a second seal ring is arranged in an area formed by the slope surface, the bearing and the drive shaft in a tensioning mode. The sealing structure at the end of the drive shaft can effectively prevent lubricating oil from leaking between the bearing and the seal sleeve.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of drive shaft end sealing configuration.
Background technique
The drive shaft end sealing should possess the requirement that prevents that axle, shell and casing internal gear lubricant oil from leaking; Yet the stuffing box gland of drive shaft end sealing configuration of the prior art is that rigidity contacts with bearing, and sealing effect is poor, and if when O-ring seals is installed, O-ring seals is caused damage, lubricant oil will release between bearing and stuffing box gland.
The model utility content
The purpose of the utility model provides a kind of drive shaft end sealing configuration, and it can effectively stop lubricant oil between bearing and stuffing box gland, to release.
The above-mentioned technical purpose of the utility model is achieved through following technological scheme: a kind of drive shaft end sealing configuration, be provided with in comprising bearing axle housing, be placed in live axle in the bearing, be placed in the outer and sealing skeleton that is connected with the interference of axle housing inwall of live axle, at the stuffing box gland that seals between skeleton and the live axle; Have groove one on said stuffing box gland and the wall that live axle contacts, be embedded with seal ring one in the groove one; Said stuffing box gland has the inclined-plane towards live axle near an end of bearing, and swelling has seal ring two in the formed zone of said inclined-plane, bearing and live axle.
In the time of assembling, seal ring two is placed in earlier on the live axle, on live axle, puts the stuffing box gland that is embedded with seal ring one again; Because seal ring two is to be placed in separately on the live axle; So in fitting tight circle two, seal ring two is not fragile, thereby; Make seal ring two fitted seal cover further realize the end sealing of live axle, effectively solve the easy problem of lubricant oil in the background technique from releasing between bearing and the stuffing box gland.
Preferred as the utility model, this kind end sealing configuration also comprises the dust cover that is placed on the live axle; The end of axle housing has flange; Have the groove two that matches with flange on the dust cover.
The flange of axle housing is embedded in the groove two of dust cover, thereby stops outside material, and for example, rainwater or muddy water etc. get into.
Preferred as the utility model is provided with jump ring between said sealing skeleton and the bearing.
Preferred as the utility model, said bearing is a ball bearing.
In sum, the utlity model has following beneficial effect:
1, the utility model can effectively be realized the end sealing of live axle, prevents that lubricant oil from releasing between bearing and stuffing box gland;
2, the utility model can effectively prevent exterior materials, like rainwater or muddy water etc., gets in the axle housing.
