Description
Technical field
The utility model is related to field of textile machinery, relates more specifically in ring throstle (hereinafter referred to as spinning frame)
Yarn-spinning spindle.
Background technology
Spinning frame is by the device of rove bar spun yarn (spun yarn) 9.Spinning frame includes drafting system, twisting and winding system
System.Fig. 1 is the schematic diagram for the usual structure for showing spinning frame, illustrated therein is spindle.Reference picture 1, first, drafting system 2 are led
Stretch the rove bar 1 of supply and make the spindle of rove bar 1, then twist the yarn 9 being pulled by twisting and winding system
Be wound on Yarn-spinning spindle 3.
Yarn-spinning spindle 3 is in twisting and winding system, and when Yarn-spinning spindle 3 is rotated, yarn 9 is by the steel on ring rail 4
Neck 5 and wire loop 6 are twisted.More specifically, while Yarn-spinning spindle 3 is rotated, ring rail 4 and rings 5 are along Yarn-spinning spindle 3
Axis direction is moved back and forth, and yarn 9 passes through the wire loop 6 being installed on rings 5, so that as wire loop 6 is slided on rings 5
(that is, being rotated relative to rings 5), so that yarn 9 is twisted while being wound on Yarn-spinning spindle 3.
Yarn-spinning spindle 3 is driven by spindle band 7.The revolution of Yarn-spinning spindle 3 is 12000 rpms to 25000 rpms.
Twist triangle zone domain and the air ring between drafting system 2 and Yarn-spinning spindle 3 are also show in Fig. 1.In drawing-off
Twizzle 8 is provided between system 2 and Yarn-spinning spindle 3.
Fig. 2A and Fig. 2 B are the sectional views of the Yarn-spinning spindle according to prior art, and Fig. 2 B are the bottoms of Fig. 2A Yarn-spinning spindle
Enlarged drawing.
Reference picture 2A and Fig. 2 B, the Yarn-spinning spindle mainly includes bolster 10, spindle blade 31 and aluminum casing 32.The top of spindle blade 31

Step between first upper end of 100 (outer rings 102) and the upper end of housing 200 and the main part 502 and wide diameter portion 501 of wharve 500
Axial gap preferably is left between face 503, in order to which wharve 500 is rotated relative to housing 200 and outer ring 102.Housing 200 it is upper
Radial clearance preferably is left between end and the wide diameter portion 501 of wharve 500, in order to which wharve 500 is relative to housing 200 and outer ring
102 rotate.
As shown in Figure 3 A and Figure 3 B, the internal diameter at the position of the assembling ball bearing unit 100 of housing 200 is more than remainder
Internal diameter.More specifically, the outer ring of the internal diameter and ball bearing unit 100 of the Part I 201 being located on the upside of axial direction of housing 200
102 external diameter is substantially equal, and outer ring 102 is embedded in (preferably merga pass radial direction holding screw is matched somebody with somebody in press-fit or small―gap suture
Fixed stop) into the Part I 201.The internal diameter of the Part II 202 being located on the downside of axial direction of housing 200 is less than first
Points 201 internal diameter, so as to form the step surface 203 radially extended between Part I 201 and Part II 202.Can be with
Outer ring 102 is supported by the step surface 203.
As shown in Figure 3 A and Figure 3 B, the axial length of the ball bearing unit 100 in present embodiment is larger, so as to by
One ball bearing unit supports whole Yarn-spinning spindle.Preferably, axial length (that is, the axle of outer ring 102 of ball bearing unit 100
To length) be more than or equal to housing 200 axial length 2/3.
Flange 204 and screw thread (not shown) are also formed with housing 200, can be via nut 600, packing ring 700 and method
The Yarn-spinning spindle is installed on rail plate by orchid 204.
The assembling of the Yarn-spinning spindle of simple declaration present embodiment below.First, assembling ball bearing unit 100, i.e., by ingot
Bar 400, ball 101, outer ring 102 are assembled into ball bearing unit 100；Then, by polished rod or aluminum casing 300 and ball bearing unit 100
Spindle blade 400 be pressed into from the axial two ends of wharve 500 in wharve 500；Finally, above-mentioned assembly is fitted into housing 200.
Assemble method not limited to this, for example, it is also possible to be pressed into polished rod or aluminum casing 300 first with blade and keeper
In wharve 500, ball bearing unit 100 is installed in housing 200, then the wharve 500 with polished rod or aluminum casing 300 is pressed
It is coupled on spindle blade 400.
The characteristics of Yarn-spinning spindle of present embodiment, includes：Simple in construction, energy consumption is small, non-maintaining, low cost.
As described above, compared with existing Yarn-spinning spindle, the part of the Yarn-spinning spindle of present embodiment is few, simple in construction.
In the present embodiment, the roller bearing and sliding bearing in existing Yarn-spinning spindle are instead of with ball bearing, therefore, in this reality
In the Yarn-spinning spindle for applying mode, it is convenient to omit ingot hook.
In the present embodiment, the roller bearing and sliding bearing in existing Yarn-spinning spindle are instead of with ball bearing.Ball
Bearing contacts for point, and friction ratio has the friction of the existing structure of roller bearing and sliding bearing small.Inventor passes through BearinX
Calculating has verified that compared with existing Yarn-spinning spindle friction reduces 30~40%.Due to the reduction of friction, energy ezpenditure
Reduction.So the Yarn-spinning spindle of present embodiment can reduce energy consumption for terminal user.
The Yarn-spinning spindle of present embodiment is lubricated by fat, and fat can be used for the situation of high speed, low friction and low noise.
During Yarn-spinning spindle is run, it is not necessary to attended operation.The Yarn-spinning spindle of present embodiment can be realized non-maintaining.So with having
Compared with the Yarn-spinning spindle of oil lubrication, the Yarn-spinning spindle of present embodiment can be saved for user maintenance cost and manpower into
This.
