Bearing inner race be arranged on rotating shaft 1 on, flexible member 3 is arranged in bearing chamber 4, bearing outer ring be mounted in bearing room and
Contact with flexible member 3.5 interference fit of rotation stop phantom ring is sleeved on one end of bearing outer ring, is located at and leans on rotation stop phantom ring
Nearly bearing chamber one end evagination is evenly arranged three and leads tooth 6；On the wall of bearing chamber side, correspondence is led tooth and arranges guide groove 7 one by one；Lead tooth pair
Guide groove is answered to insert one by one, the axial float displacement during decrement ＞ rotating shaft work of the insertion depth ＞ flexible members for leading tooth；
Lead flank and lead and coordinate for gap between groove sidewall；It is interference fits between the bearing outer ring other end and bearing chamber.Lead flank
Face and the fit tolerance led between groove sidewall are G7/h6.
What the flexible member in this embodiment was selected is wavy spring packing ring；Again during specific embodiment, concrete equal function
Butterfly spring or other flexible members can also apply in the present embodiment.
Rotation stop phantom ring in this embodiment is tight with one end of bearing outer ring, rotation stop phantom ring and axle by hot cover process
Bearing outer-ring laminating is tight, forms the first assembly.
Rotation stop phantom ring and bearing outer ring in the specific implementation, can be also integrally formed by this embodiment.Rotation stop phantom ring with
Bearing outer ring can merge makes that a list is holistic and the bearing outer ring with rotation stop lag function, only has so as to be formed
Turn a New function bearing of lag function.
The matrix mounting means of this embodiment：
Rotation stop phantom ring interference fit is sleeved on one end of bearing outer ring, is located near bearing chamber one on rotation stop phantom ring
End evagination is evenly arranged leads tooth no less than one；On the wall of bearing chamber side, correspondence is led tooth and arranges guide groove one by one；Lead tooth correspondence guide groove
Insert one by one, the axial float displacement during decrement ＞ rotating shaft work of the insertion depth ＞ flexible members for leading tooth；Lead flank
Face and lead between groove sidewall for gap coordinate；It is interference fits between the bearing outer ring other end and bearing chamber side wall.Rotation stop is servo-actuated
Ring is tight with one end of bearing outer ring by hot cover process, and rotation stop phantom ring is fitted with bearing outer ring closely, forms first and assembles
Body.First assembly and rotating shaft are assembled, it is ensured that rotating shaft carries out tight set assembling with bearing inner race, forms the second assembly.
Flexible member is put in bearing room, the 3rd assembly is formed；Second assembly is assembled with the 3rd assembly, and is ensured
Rotation stop phantom ring lead tooth guide groove corresponding in alignment bearings room one by one after insert, lead the insertion depth ＞ flexible members of tooth
Compress axial float displacement when ＞ rotating shafts of taking measurements work.Lead to coordinate for minimal clearance between tooth and guide groove and (coordinate optional
With G7/h6), it is ensured that leading between tooth and guide groove can be with moving axially relative, and without circumferentially rotating.Bearing outer ring opposite side and bearing chamber
Between be interference fits, it is ensured that while bearing outer ring and bearing chamber axiality, between can carry out it is moving axially relative.Outside bearing
Circle end face prop up flexible member after, bearing continue axially-movable, by flexible member precommpression certain size, it is ensured that flexible member with
Under the synergy of rotating shaft, the bearing clearance of bearing is eliminated；Ultimately form assembly；So far, bearing floating is servo-actuated and bearing outside
Circle spline structure assembling is completed.
The course of work of the present embodiment：
When rotating shaft 1 is with 2 inner ring normal rotation of dynamic bearing, according to actual condition demand, rotating shaft may occur axial displacement,
Now, there is overall axial displacement in the first assembly under the drive of rotating shaft；Now, because arrange on rotation stop phantom ring 5 three
Root is inserted after leading three corresponding guide grooves 7 of 6 alignment bearings room 4 of tooth, and leads the decrement of the insertion depth ＞ flexible members of tooth
Axial displacement when ＞ rotating shafts work.Lead, it is ensured that
Leading between tooth and guide groove can be with moving axially relative, and without circumferentially rotating；No matter the first assembly under the drive of rotating shaft 1 to X-axis
Positive direction or negative direction motion, flexible member 3 all can prop up the end of outer ring one end of bearing 2 in the presence of elastic force in real time
Face, while leading the cooperation of tooth 6 and the guide groove 7 in bearing room on rotation stop phantom ring 5, also ensure that bearing occurs axle in bearing room
While motion, the outer ring of bearing will not circumferentially rotate.When outside operating mode recovers normal, the second assembly and the 3rd
The relative position of assembly restPoses, and mechanism can still ensure normal operation, and play the rotation stop effect of bearing outer ring.
In addition to above-described embodiment, the utility model also proposes following examples 2：
