Description
Technical field
The present invention relates to a kind of driven journal end face densification device, refer more particularly to a kind of driven journal end face densification device of High Rotation Speed.
Background technique
Obturage technically at contemporary transmissions spindle nose end face, being all generally adopt graphite annulus and rubber ring to seal, for the rotational speed more than 9000 revs/min, is need to be sealed by the high-speed slide of graphite annulus and runway end face.For preventing runway and bearing from having relative sliding, have employed the nut be tightened on axle and compressing spacer sleeve, thus making the form that the frictional force of runway and bearing and gear shaft increases.Under this structural type, need spacer sleeve, nut, the parts such as lock washer could be installed and tighten up runway, and number of spare parts is many; Tightening up due to nut on the other hand, makes runway produce distortion, can produce destruction, be unfavorable for the work of graphite annulus to high-precision runway end face plane degree.Because the linear velocity that rubs in high-speed slide process greatly easily damages graphite annulus.The rolling closing in mode adopted between graphite annulus and fitting seat fixes graphite annulus, and make graphite annulus complex-shaped, difficulty of processing is large.Thus make manufacture and operating cost all higher.
Summary of the invention
The object of the invention is to solve above-mentioned deficiency, designing a kind of new driven journal end face densification device.
For achieving the above object, the present invention by the following technical solutions: a kind of spindle nose face seals comprises end face and to obturage housing, wavy spring, positioning ring, graphite annulus, positioning ring seal ring, collar, block and runway, bearing, transmission shaft, runway seal ring, the transmission shaft shaft shoulder.Wherein end face housing of obturaging is mounted in casing, and graphite annulus is fixedly mounted in positioning ring, and positioning ring is arranged on end face and obturages limited by wavy spring and block, collar in housing.Runway is arranged on the transmission shaft shaft shoulder near bearing.
Described graphite annulus is a rectangle ring body, comprises a graphite annulus and to obturage end face, and the wavy spring obturaged in housing by being arranged on end face promotes the end face of obturaging of graphite annulus in positioning ring and is close to forward runway and obturages end face.When transmission shaft High Rotation Speed, runway end face and graphite annulus end face of obturaging of obturaging produces and slides, and plays to lubricant oil in transmission casing the effect of obturaging.
Obturage positioning ring seal ring that housing and carrying out between runway and transmission shaft seals and runway seal ring of described positioning ring and end face is all employing 0 type rubber ring.
The described transmission shaft shaft shoulder is designed with two symmetrical shaft shoulder grooves on axis.
Described runway is a cirque body, in order to keep the balance of transmission shaft under high speed rotating, the inner ring axis of the end face of obturaging of runway is designed with two symmetrical runway positive stop lug boss, runway being fixedly mounted on the transmission shaft shaft shoulder by the axis of two runway positive stop lug boss and the transmission shaft shaft shoulder being designed with two symmetrical shaft shoulder fit depressions, driving runway to rotate by transmission shaft.Installation end face on runway is close to bearing inner ring and is installed.Runway on runway end face and graphite annulus end face of obturaging of obturaging seals by sliding, and obturages effect for improving and reduce the wearing and tearing of graphite annulus, and the obturage planeness of end face design of runway is not more than 0.6 μm, and roughness is not more than 0.2 μm.For runway dispels the heat when high speed rotating, the outer shroud of runway has a V-type annular groove.
Described end face is obturaged, and housing is uniform in inner ring is welded with 4 blocks, and is designed with an annular snap ring recess in the inner ring of housing of obturaging near the end face outside block.
Described positioning ring comprises front ring body and rear ring body, positioning ring boss, positioning ring groove.Graphite annulus is arranged in front ring body graphite ring seat, and be drive fit between graphite annulus and graphite ring seat, magnitude of interference is 0.12 ~ 0.85mm.At positioning ring outside design 4 uniform positioning ring boss, the positioning ring groove that the central position of each positioning ring boss has a block obturaged on housing with end face to match.Obturage in housing when positioning ring is arranged on end face, circumferencial direction is spacing by block; Axially by be arranged on end face obturage housing inner position ring rear ring body on push ahead wavy spring and before pinning positioning ring the collar of ring body end face carry out spacing.
Beneficial effect of the present invention is: simplify the improvement with structure due to driven journal end face densification device number of spare parts, graphite annulus diameter reduces, make the linear velocity reduction in the course of the work of primary seal end face, fricative heat can be reduced, improve reliability and the working life of face seals.
