Maglev health beauty weight loss health beds is a Magnetic support for a complex electronic and mechanical high-tech products of the alternative, suspended in the air bed, its role as a magnet beneath the bedstead and bed base interactions of magnets bedstead bed base and leave them suspended, and then to bed magnetic base of the bedstead can transform the whole magnetic vibration; before and after; around; rocking movement, etc.; in the bedstead campaign process, without any linkage, or gears or belts, twisted Lian passive body without motor or hydraulic arm of the initiative institutions, and its actuation process without any oil or exhaust noise and pollution generation, magnetic levitation force bed, and consumption of reactive small, control is simple, safe and reliable, such a novel concept, design reasonable, full-featured, performance, a wide range of applications; can be described as a collection: physical therapy, fitness, leisure, sleep and other motor function as one design.

磁悬浮养生美容减肥健康床是一种以磁力支撑，为一种电子与机械复合之另类高科技产品，悬浮於空气中的床，其作用为床架下方的磁体与床底座磁体相互作用而使床架离开床底座而悬浮起来，再以床底座磁极之变换而使床架能做上下磁震动；前后；左右；摇摆等运动；在床架的运动过程中，无需任何连杆，或齿轮或皮带，绞炼之被动机构，亦无需马达或油压臂之主动机构，且其作动过程中无任何噪音与油污或废气的污染产生，磁悬浮床作用力大，耗功小，控制简便，安全可靠，此种构思新颖，设计合理，功能齐全，性能优良，应用广泛；可谓集合：理疗，健身，休憩，睡眠等多种运动功能为一体的设计。

Furthermore, the forming die can realize single punch extrusion according to different die carriers and equipment, double punch extrusion in opposite directions, as well as the extrusion of the helical cylindrical gear with big helix angle.

本发明结构简单，易于制造、安装，可根据不同模架和设备实现单个冲头挤压，也可实现两个冲头对向挤压；可以实现大螺旋角齿轮的挤压；成形力小，下料精度要求低。

The primary purpose of developing the four-tooth difference harmonic drive is to decrease the stress in flexspline under the condition of smaller transmission ratio. In this paper, we focused our study on its accuracy characteristics.

采用四齿差双波谐波齿轮传动的主要目的是为了在小传动比情况下不致影响柔轮的强度，本文主要研究其精度特征。

It should be said GALLUS machine meshing gear teeth, there was a small staves of opportunities.

不该说GALLUS的机械是歪齿轮啮合的，呈现齿杠的时机小。

The helix angle on the worm is generally quite large, and that on the gear very small.

螺旋角对蠕虫一般都相当大，这对齿轮非常小。

In the design of crossed-helical gears, the minimum sliding velocity is obtained when the helix angle are equal.

在横渡螺线齿轮设计，当节面角是相等的时，极小值滑的速度得到。

In prior art, the position and attitude control for antenna can only realized in small-scale, and lies in the means of hydraulic cylinder, gear box and rotary joint.

目前天线的位姿控制还都在小范围内实现，实现的手段是通过液压缸、齿轮箱和旋转关节等刚性结构的运动。

Screw on the choice of friction loss, high efficiency, high precision, long life of the ball screw, the electrical selected stepper motor, motor and the ball screw with gear deceleration.The main to modify the lathe is to modify the portrait, horizontal enter to the system in the Whole modification process and choose the automatic knife rest and be processed the thread need by pulser. The whole control system with the CPU of JKW-15T is to control the machine for center, through a plait distance drive tool machine an equipments to carry on control to attain need of process degree.

整个改造过程主要对车床纵、横向进给系统进行改造，丝杠选用摩擦损失小，效率高，精度高，寿命长的滚珠丝杠，电机选用步进电机，电动机与滚珠丝杠用齿轮减速；刀架改造成能自动换刀的回转刀架，由脉冲发生器来加工所需要的螺纹；整个控制系统以JKW-15T型号的单片机为中心，通过编程对机床的驱动设备进行控制以达到所需要的加工程度。

The frequency about 30KHZ small may quench Φ10 about the high accuracy axis,the hard level maintains in 1 mm,may quench ￠250 the diameter macro-axis,also may quench Φ500 about the gear.
