主轴

At present, there are drilling more than 150 plants, with an annual output of various drilling about 1 million units, export over 20 million units, the drilling of speed through a pulley shift to resolve the pagoda, the governor need to stop the process, open the protective Enclosures, manual transmission, and other procedures, the process cumbersome and poor security, and is governing, not transferred to the spindle speed corresponding to the different materials of various aperture drilling at the best speed, the production efficiency is low.

目前，全国有钻床厂150多家，年产各种钻床100万台左右，出口20多万台，这些钻床的变速都是通过一对宝塔皮带轮换档解决的，调速过程需要停车、打开防护罩，手工换档等程序，操作过程繁琐且安全性差，并且是有级调速，不易使主轴转速调到对应于不同材质的各种孔径钻削时的最佳转速，因此生产效率也低。

ZL02 2 33851.9, the performance of its fast stepless speed regulation Pulley is a traditional pagoda shift by less than the governor, the product also has spindle speed digital form, and other new technology features, is the latest drilling replacement products.

数显无级调速钻床于2003年3月19日获国家专利（专利号ZL02 2 33851.9），其快捷无级调速之性能是传统宝塔带轮换档调速所不及的，该产品还配有主轴转速数显表等新技术功能，是钻床更新换代的最新产品。

This article elaborated a 12 level of rotational speed C6132 horizontal lathe headstock design process, the headstock uses to support the main axle and to cause it revolving.

本文阐述了一个12级转速的C6132卧式车床主轴箱的设计过程，主轴箱用以支撑主轴并使之旋转。

The topic is The design of the drilling machine fixture for Processing lathe shifting fort upper thread bottom hole, and lathe shifting fort located in the lathe speed institutions, mainly from the shift so that the spindle rotary movement of workers in accordance with the requirements of work, have the necessary speed and torque Role.

本课题是车床拨叉上螺纹底孔加工钻床夹具设计，而车床拨叉它位于车床变速机构中，主要起换档，使主轴回转运动按照工作者的要求工作，获得所需的速度和扭矩的作用。

CNC lathe spindle speed due to very high, for ease of workpiece clamping, multi-use high-speed hydraulic power chuck, because it is in the production plant has passed a strict balance, with a high speed (speed limit up to 4000 ~ 6000r/min), high clamping force (push pull for the largest 2000 ~ 8000N), high-precision, adjusting claw convenience, through-hole, long life and so on.

由于数控车床主轴转速极高，为便于工件夹紧，多采用液压高速动力卡盘，因它在生产厂已通过了严格的平衡，具有高转速（极限转速可达4000~6000r/min）、高夹紧力（最大推拉力为2000~8000N）、高精度、调爪方便、通孔、使用寿命长等优点。

The round trip is driven by servomotor, matched up with precision ball screw and wire slide rail, to smooth the round trip of the blade and position accuracy.

切刀与主轴采用无级变速AC马达。5。行程以伺服马达驱动，配合精密滚珠螺杆及线滑轨，切刀行程顺畅，定位精确。

. （6） The output signal of spindle relay is connected to the twenty-third Pin i.e.

输出主轴继电器信号分别连接：37针IO板（COM2）第23脚（即：OUT2），20脚

By the contact elemen analysis the shrink fit in impeller with shaft of steam turbines, and the contact stress of shrunk-on disc have been investigated.

套装在轴上的叶轮工作时，由于离心力的影响，会使叶轮内孔增大，以至叶轮与轴之间有可能产生间隙，因此，叶轮与主轴配合必须采用过盈配合。

The fifth chapter studied the key shaft, linking brace and pole base of experiment platform, using the finite element analyzing software, providing the intension checking and structure optimizing

第五章，利用有限元分析软件对实验台的关键件主轴、曲柄联接柱及长杆固定座进行有限元分析，并进行了强度校核和结构优化。

The machine which adopts two main shaft head for cutting is special for plate which is more than 300 mm and can minimize the processing period.

采用两个主轴头切削，特别适合加工大于300mm板材，缩短加工周期。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
