滑差轴 Air  Friction

1YR-700(气压式滑差轴)

这种型号大的特点是,滑差环与卷芯之间的转动力矩是通过调整主轴中气压高低的方法来实现的,从而控制每个滑差环所带动的卷芯,这样就实现了分切是,不同卷材之间由于卷材厚度的差异导致的张力不均引起的复卷问题。

另外,由于是气压控制凸键的收放,所以装卸卷材非常方便;因为特殊的密封增压方式,主体内页没有橡胶气囊,几乎不用维修。

相对机械式气胀轴,不易产生污染,所以特别适用于食品包装行业。

φ3’’76.2mm)纸芯专用。

英文:Most of  differential shaft has side—friction controlled slip between each cartridges made of force by spring or air cylinder aside .

It is known that the constant friction between each cartridge is rarely accomplished in this type .

The first air friction we present works by air pressure controlled equally to each cartridges ,so slip of each cartridge is even which builds precisely controlled rolls.

Loading /unloading of a finished roll is really easy because core is gripped by lugs inflated by air.

Unlike other air friction shafts,this product  has no tube in it ,so no trouble because of tube.

2、YR-700A(气压式滑差轴)

YR-700型号,每个滑差环增加了侧向轴承,使得卷材更容易脱附出来。

英文:Addition of bearing cartridge which helps roll to move horizontally.

3、YR-701(机械式滑差轴)

YR-700相比较,此型号产品适用于高张力20KG以上,厚度150μm,卷材克重为250g以上的卷材。并且可根据卷芯的内经制作轴的外径尺寸。

英文:As  stated in YR-700,has some disadvantage because of its structure,but still applicable for heavy and think rolls.

4、 YR-702(机械式滑差轴)

此规格精度比YR-700还要好,可应用于更加精密的场合。每个滑差环两列滚珠凸键,一列的6个(共12个)在一定的立卷取时,卷芯与滑差环之间的凸键能够始终保持卷芯的真圆度和同心度;另6个滚珠全部凸起将卷芯涨紧。卷取开始,随着卷材张力增加,因设定了轴向压力,因纸张厚度不均匀造成卷材的直径差异,一旦大于设定压力则产生打滑,从而达到控制各分切卷之间张力的均衡。

分切小宽度:15mm

卷材厚度:50μm-500μm

因没有橡胶气囊,几乎无需维修,滑差环外径可依卷芯内经尺寸。

英文:One step further than YR-700series ,this product performs more precise work ,Friction which makes roll slip is still everly controlled .

There are two columns of ball bearings(6*2=12)per a cartridge, 6of 12are aligning concentric between core and shaft by constant spring force from in to out .

The rest are clamping a core tightly when shaft starts rolling

Minimum slit width available is 15mm

Common film thinkness is between 50-500microns .

No tubes are needed .

OD of the cartridges can vary up to core size .
