Specific embodiment

As shown in Figs. 1-5, the bearing arrangement of the slip shaft of leakproofness can be improved described in the utility model embodiment, institute is real The technological means applied purpose to be achieved is, solves traditional slippage shaft device because the fault of construction of its bearing portion makes component phase Mutually cooperation imprecision, and then caused expansion set component internal is easily accessible dust clast and seriously affects slip shaft cutting accuracy The technical issues of, during solving the technical problem, first have to overcome in bearing assembly using corresponding technological means The component at least two positions be fixedly connected with problem, first, the connection between the retaining ring of bearing and bearing corresponding site is usual Using the fixed form of gluing, it is lower not only to seal grade, it is more serious will lead to it is heated after it is easy to aging, fall off, final shadow Ring the operation of entire slippage shaft device；Second, the retaining ring right side of bearing is plane, and it is directly assembled to expansion set component Interior, the change still not a bit so far of this assembling mode is not also changed the defect using corresponding technological means Into, therefore, current slippage shaft device is directly exposed because the defect can frequently result in expansion set component, make dust clast be easy into Enter.

In conclusion the basis that the technical solution adopted in the utility model is implemented, is by end ring 3 and axis first Bearing plate 4 forms the relationship for the connection that cooperates, and is then because installing matching relationship between end ring 3 and expansion set 1, finally It realizes with 2 application process of existing expansion set 1 and slippage component, thoroughly overcomes two point defects appeared above.

Installation matching relationship between the end ring 3 and bearing plate 4 of arrangement above is analyzed:

The bearing plate 4 implemented is adjacent with the slippage component 2 in application apparatus in installation site, the bearing implemented Retaining ring 3 is then adjacent with the expansion set 1 in application apparatus in installation site, 4 outer ring of bearing plate therein as with end ring 3 The fixation anchor ring of secure fit connection, the fixation anchor ring are set to the outer ring of bearing portion 5 in position, and this fix anchor ring with The mode of annular array is uniformly distributed several axially position components 41, it is preferable that used in the utility model embodiment Axially position component 41 includes screw, but used component is not limited to screw, each axially position group according to actual needs The fixed-direction of part 41 is identical as the driving shaft installation direction of institute's application apparatus；It at the same time, is realization axial direction and radial both sides The fixing seal means of position, 5 outer ring of bearing portion implemented are equipped with several radial positioning components 42, it is preferable that practical new at this In type embodiment, used radial positioning component 42 includes screw, but used component is not limited to according to actual needs Screw, the fixed-direction of each radial positioning component 42 and institute's application apparatus have the initiative the radial direction of axis.

Correspondingly, the fixed end face 31 of a ring shape, tool is arranged towards the one side of bearing plate 4 in the end ring 3 implemented When body is implemented, the position of the fixed end face 31 of the annular is set to the inner ring of implemented end ring 3, the fixed end face 31 of this annular Anchor ring on uniformly open up several fixing threaded holes 32 for secure fit bearing plate 4, each fixing threaded hole 32 and bearing pressure Each 41 position of axially position component of plate 4 corresponds to one by one, thus by determining the axial direction on the fixed anchor ring of bearing plate 4 Hyte part 41 is tightened against in the fixed corresponding fixing threaded hole 32 in end face 31 of annular of end ring 3, is realized end ring 3 and axis Bearing plate 4 carries out axial seal positioning；At the same time, to realize the axial fixing seal means with radial both sides position, implemented 3 inner ring of end ring fixation hole for being cooperatively connected with radial positioning component 42 be set finally pass through axially position and diameter To positioning, make end ring 3 and 4 fixing compact of bearing plate, and not easy to fall off；

Further, for the dust seal performance for enhancing expansion set 1, the end ring 3 implemented increases towards the one side of expansion set 1 If the chuck 33 of an annular, so that end ring 3 is covered in expansion set 1 towards the outer ring surface of 1 one side of expansion set of institute's application apparatus and fix Face, since 1 stationary plane of expansion set of institute's application apparatus is usually there are certain space being recessed inwardly, which forms solid Determine slot position, set chuck 33 is caught in inside the corresponding fixed groove face of expansion set 1, thus make end ring 3 outer circuit covering in On the basis of 1 stationary plane of expansion set, also by fixation groove face further clamping, sealing of the chuck 33 to expansion set 1, dust or broken is reduced Bits enter in expansion set, greatly improve dust seal performance.

The bearing arrangement of the slip shaft of leakproofness can be improved described in the utility model embodiment, firstly, by using axis The axially position component 41 of bearing plate 4, radial positioning component 42 the screw hole positioning lock with 3 corresponding position of end ring respectively Tightly, to realize two-way positioning, overcome that traditional bearing component and retaining ring inner hole caused using gluing be easy by heat ageing, The defects of falling off is formed in conjunction with anticreep between the outer ring for the bearing plate 4 implemented and the fixed end face 31 of the annular of end ring 3 Portion；Then, by using the end ring 3 with chuck 33, cooperate when being tightly connected with the expansion set 1 of application, chuck 33 with it is swollen Set 1 forms sealing state, forms oil seal part between the outer end and expansion set 1 of the end ring 3 implemented.

As seen in figs. 5-6, the utility model is implemented bearing arrangement is in use, with the expansion set 1 of institute application apparatus, sliding Poor component 2 matches, and constitutes a slip axle housing group, and it is sliding several groups can be arranged on sliding main shaft in applied slippage shaft device Deviation shaft set group, the installation for expansion set 1, slippage component 2, using state of the art, on the main shaft of applied slip shaft With air flue, air flue is connected to inside expansion set 1 by air inlet group, is worked if being respectively set on the end face of 1 arranged on left and right sides of expansion set Consent, piston is arranged in each piston hole inside, in positional relationship, due to the expansion set 1 of slippage component 2 and adjacent slip axle housing group It is adjacent, to make the slippage component 2 of adjacent slip axle housing group to its same group retaining ring and swollen by the piston motion of expansion set 1 The axial displacement of 1 position generation to the right is covered, thus rewinding cylinder tensioner.
