It is characterised in that, in the tube (80) of the elastic component (8), at least part of the surface of at least one passage opening (6) is between the two elastic bushes (81). The bearing bush (1) has a recess (2) on its outer periphery, from the leading side (10), which reaches at least to the passage opening (6) in the tube (80) of the elastic component (8) behind the plane of its approaching edge.

Description

A kind of high-speed bearing that has flexible member especially for open-end spinning frame
Technical field
The present invention relates to a kind of high-speed bearing that has flexible member especially for open-end spinning frame, this spinning machine comprises an interior journal box of sleeve that is installed in flexible member, this sleeve is fixed by the two ends that it has resilient bushing, and flexible member is provided with at least one through hole.
Background technology
In order to improve work efficiency, high-speed bearing is especially for installation open-end spinning frame rotor and to surpass 40000min -1The high-speed bearing of speed operation, be installed in the flexible member, the flexible member of describing among the CS AO 238202 can be up to 80000min -1Speed under use, describe among the CS AO 256305, or, also can be used for surpassing 80000min based on the another kind of flexible member of this conception of species -1Speed.This two type of elastomeric element all is provided with bypass through hole (that is, air bias current hole), crosses bearing to prevent unnecessary air communication.
In the flexible member of describing in CS AO 238202, these through holes are arranged on the middle part of its sleeve.
In the flexible member of describing in CS AO256305, the length of high-speed bearing journal box increases, and the scope that the length of elastic component increases is subjected to the restriction of the length of installing space in the bearing body, therefore, described through hole must be arranged on the front portion of this flexible member, that is, and in the anterior resilient bushing.At this moment, described hole is by the rubber part of resilient bushing, and leads to installed surface, considers dimensional problem, and free end one side of the rubber part of the front side resilient bushing of flexible member must be towards the rear side resilient bushing of flexible member.Yet, the bypass through hole that processing is provided with like this, feasible requirement to processing technology has improved.In addition, the orientation of the front side resilient bushing of described flexible member causes the damage of himself sometimes when the dismounting machine.At last, but be not to be least importantly, whole side effect that this arrangement is involved will produce adverse influence to the dynamic characteristics of the installation of rotor.
Summary of the invention
The present invention will overcome this speed that is used at present exactly and surpass 80000min -1The shortcoming of flexible member, and allow to be used for speed at present and be lower than 80000min -1The use of speed of flexible member.
According to the present invention, a kind of high-speed bearing that has a flexible member of open-end spinning frame is provided, it comprises a journal box, this journal box is installed in the sleeve of flexible member, this sleeve is equipped with a resilient bushing in each end at its two ends, and this flexible member is provided with at least one through hole, in the sleeve of flexible member, the at least a portion on the surface of at least one through hole is arranged between two resilient bushings, and the journal box of high-speed bearing is provided with a gap starting from the external peripheral surface of its front side, in the sleeve of flexible member, this gap pass to through hole at least a portion below.
Description of drawings
Fig. 1 shows the cross-section structure of the bearing block that the open-end spinning frame rotor is installed.
The specific embodiment
Below, with reference to being installed, open-end spinning frame rotor 4 comes an example of the present invention is described.
High-speed bearing comprises a journal box 1, and this journal box is installed in the inner chamber of flexible member 8.This flexible member is made of a sleeve 80, and sleeve 80 has known resilient bushing 81 in its end.By means of the excircle of resilient bushing 81, flexible member 8 is installed in the known bearing block 7.
In its part between two resilient bushings 81, sleeve 80 has through hole 6.Be arranged at the journal box 1 of the high-speed bearing in flexible member 8 inner chambers, it closes on the excircle of front side of the rotor 4 in the illustrated example, be provided with gap 2, in the sleeve 80 that places near the flexible member 8 of the front side 10 of high-speed bearing journal box 1, this gap extends to the rear at the edge of through hole 6 at least, like this, the space 5 that limits by two resilient bushings 81 that just can freely be communicated with the space 3 of sleeve 80 inboards and sleeve 80 outsides, promptly, in illustrated example, the space 3 and the space 5 that are communicated with rotor 4 back, wherein space 5 is by the sleeve 80 of flexible member 8, two resilient bushings 81 of flexible member 8, and a wall of bearing block 7 limits, and has just like the air outlet slit shown in the figure 70 on this wall.With regard to its side effect, the dry problem of speed change and lubricant for example, air flows out sleeve 80 by this passage from the front side 10 of high-speed bearing, enter in the space 5 between the resilient bushing 81 in sleeve 80 outsides, promptly, in illustrated example, air flows into from the space around the rotor 4 in the free space 5 of bearing block 7 in the outside, and the space by high-speed bearing inside not.
On the excircle of the front side 10 of high-speed bearing journal box 1, by in the predetermined length scope, reducing the outside dimension of high-speed bearing journal box 1 by the front side 10 of journal box, and constitute gap 2.
In illustrated example, both having made is end at the resilient bushing 81 that is positioned at rotor, on the sleeve 80 of flexible member 8 through hole 6 is being set still.The rear portion of rotor 4 is inserted into sleeve 80, and high-speed bearing axle journal 1 closes on the excircle of front side 10 of rotor 4 at it, is provided with gap 2, and this gap extends to half place of through hole 6 along the longitudinal axis of the sleeve 80 of flexible member 8.In addition, in not shown another example that goes out, the corresponding length difference in the position of through hole 6 and the gap 2 on 10 excircles of the front side of high-speed bearing journal box 1 thereof, it can be adapted to the length and the position in the sleeve 80 of flexible member 8 thereof of high-speed bearing journal box 1.
The mutual size relationship in the gap of through hole 6 and high-speed bearing journal box 1 can be adapted to known demand, that is, and and interior required air quantity of unit interval by such " bypass " passage that produces.
