Detailed description of the invention
Fig. 1 is the cross-sectional view of the spindle axis of false twister of the prior art；
Fig. 2 is the cross-sectional view of the spindle axis of false twister of the specific embodiment of the invention.
Specific embodiment
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
Referring to Fig. 2, spindle axis of false twister include mandrel 10, around mandrel 10 bearing 20 and be located on mandrel 10 and and bearing
20 along 10 axial direction of mandrel driving member 30 spaced apart from each other.
The bearing 20 includes bearing outer ring 21, between bearing outer ring 21 and mandrel 10 and along 10 axial direction of mandrel
First group of rolling element 22 and second group of rolling element 23 spaced apart from each other, first group of rolling element 22 is close to driving member 30, second group of rolling
Kinetoplast is far from driving member 30.First group of rolling element 22 and second group of rolling element 23 are for realizing between bearing outer ring 21 and mandrel 10
Relative rotation.
Inner peripheral surface between the bearing outer ring 21 and second group of rolling element 23 is equipped with the damping ring around mandrel 10
24, damping ring 24 has annular groove (not labeled) of the opening towards mandrel 10, and second group of rolling element 23 is located at annular groove and mandrel
Between 10.Spindle axis of false twister is realized along the damping function of 10 radial direction of mandrel in the bottom of annular groove, and annular groove is along 10 axis of mandrel
The damping function of spindle axis of false twister in axial direction is realized to the side wall of direction two sides.That is, damping ring 24 can be real simultaneously
The damping function of existing mandrel 10 axial direction and radial direction.Moreover, damping ring 24 designs simply, and compared with prior art, dress
It is simple with process and save the time.
The material of damping ring 24 is elastoplastic, to realize damping function.
In the present embodiment, referring to Fig. 2, the first inner ring 25 around mandrel 10, the first inner ring are installed in annular groove
25 provide raceway with mandrel 10 for second group of rolling element 23.The inner peripheral surface of damping ring 24 and bearing outer ring 21 realizes that interference is matched
It closes, the annular groove of the first inner ring 25 and damping ring 24 is also interference fit, makes damping ring 24 and bearing outer ring 21, the first inner ring 25
Tight fit is realized in 10 radial direction of mandrel with damping ring 4, is avoided loosening, be fallen off.In this way, the first inner ring 25,24 and of damping ring
Bearing outer ring 21 may be implemented to rotate synchronously.
Referring to Fig. 2, the bearing outer ring 21 is divided into middle part 211 along 10 axial direction of mandrel, is located at 211 two sides of middle part
Both ends 212, the internal diameter of the end 212 is greater than the internal diameter of middle part 211, first group of rolling element 22 and second group of rolling element
23 between both ends and mandrel 10.In the present embodiment, bearing outer ring 21 can be is formed using turning technology, forms work
Skill is simple.
The one side wall of damping ring 24 is resisted against the side wall of middle part 211, and another side wall of damping ring 24 is equipped with around edge
The packaging ring 26 of mandrel 10, packaging ring 26 are contacted with the connection of the inner peripheral surface of bearing outer ring, with damping ring 24, packaging ring 26 and core
There is gap between axis 10.In the present embodiment, the inner peripheral surface of packaging ring 26 and bearing outer ring is interference fit, packaging ring 26
Position-limiting action is in axial direction played to damping ring 24.In a particular embodiment, in assembly, packaging ring 26 can compress damping
Ring 24 can make the damping vibration amplitude of damping ring 24 in axial direction smaller in this way.
Referring to Fig. 2, the inner peripheral surface between the bearing outer ring 21 and first group of rolling element 22 is equipped with around mandrel 10
The second inner ring 27, for first group of rolling element 22 between the second inner ring 27 and mandrel 10, the second inner ring 27 and mandrel 10 are the
One group of rolling element 22 provides raceway.Referring to Fig.1, in the spindle axis of false twister of the prior art, close to first group of rolling element of driving member 4
5 directly contact with bearing outer ring 3.Compared with prior art, referring to Fig. 2, first group of rolling element 22 of the present embodiment not with bearing
Outer ring 21 contacts, and avoids bearing outer ring 21 from directly bearing vibration, bearing outer ring 21 is effectively prevent to rupture.
Moreover, along 10 axial direction of mandrel, being provided with spring between middle part 211 and the second inner ring 27 referring to Fig. 2
28, one end of spring 28 compresses the second inner ring 27, and the other end compresses the side wall of middle part 211.Spring 28 plays the axis of bearing 20
It is acted on to preload.It is clearance fit, i.e. the second inner ring 27 and bearing between second inner ring 27 and the inner peripheral surface of bearing outer ring 21
It is the mating connection with gap between the inner peripheral surface of outer ring 21, in the present embodiment, the second inner ring 27 and bearing outer ring 21
Inner peripheral surface between gap be 0.Under the effect of 28 elastic force of spring, clearance fit can permit first group of rolling element 22 along axial direction
Realize the rolling of certain stroke in direction.
Referring to Fig. 2, in the present embodiment, the raceway of bearing 20 is in O-shaped arrangement, the reason for this is that: after mounting, spring 28
Elastic force acts on the raceway of first group of rolling element 22, so that loaded between first group of rolling element and its raceway.After loaded,
In one group of rolling element 22, in the extended line and mandrel 10 of the line of two contact points of any one rolling element and two raceways
The intersection point of axis is located at first group of rolling element 22 backwards to the outside of second group of rolling element 23.And it is located at core in first group of rolling element 22
After raceway on axis is loaded, the loaded raceway for acting on second group of rolling element 23 and being located on mandrel 10, so that second group of rolling
It is loaded between body 23 and its raceway.After loaded, in second group of rolling element 23, the two of any one rolling element and two raceways
The intersection point of the central axes of the extended line and mandrel 10 of the line of a contact point also is located at second group of rolling element 23 backwards to first group of rolling
The outside of kinetoplast 22.Therefore, the raceway of bearing 20 is in O-shaped arrangement.Referring to Fig.1, two groups of rolling elements of the bearing 2 of the prior art
In, the friendship of the central axes of the extended line and mandrel 1 of the line of two contact points of any one rolling element and its two raceways
Point is located between two groups of rolling elements, and therefore, the track of bearing 2 is distributed in X-type.Compared with X-type distribution, the O-shaped rolling of the present embodiment
The rigidity of support that can increase spindle axis of false twister is arranged in road.
Although present disclosure is as above, present invention is not limited to this.Anyone skilled in the art are not departing from this
It in the spirit and scope of invention, can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
Subject to the range of restriction.
