FEANOR SIPGRADE project - 高精度长度测量仪器 Upgrade of SIP Genevoise Measuring Machines

FEANOR SIPGRADE project - 高精度长度测量仪器 Upgrade of SIP Genevoise Measuring Machines

这个项目的具体创新目标是找到一种新方法延长世界著名品牌SIP的运行周期。
单轴高精度长度测量仪器.

现状
以前的SIP(SIP 550M, SIP 302, SIP 305M)校准长度测量仪器被广泛认可为长度校准的标准,目前在全球许多校准实验室也是这样。

不幸的是,由于该公司关闭,并随后被海洛斯最后被德国马尔公司收购,所以,执行这些机器的电子或软件的升级没有可能,然而,这些机械原理,品质很高,仍然可以保证所需的精度。 他们中的一些正在运行DOS操作系统和旧电脑系统,最近期的版本,直到2001年有一个限制,软件不能于Windows 95之后的系统兼容。
校准实验室出现了严重的问题,根据ISO 17025 ,在保证效率,升级,验证和该校准软件的网络能力方面。

市场的冲击会影响所有现有的SIP测量机,这是目前许多长度校准实验室真正的瓶颈。
这些项目主要的好处是延长SIP校准仪器的使用周期,以高精度和高计量的特点知名。

具体的创新目标

发展一种新型高速的齿测量仪器,用来测量斜齿圆柱齿轮,由单一的侧翼滚动的方法,带有噪声分析。

双侧翼与单侧翼滚动的方法
齿轮的功能控制通常是双侧翼的 一个齿轮和一个主齿轮不断在接触-测量瞬时轴的距离)
这种控制方法是最便宜的,因为它使用一个单一的长度测量装置来衡量瞬间齿轮轴之间的距离,但不是最有效的,因为齿轮通常有固定的安装位置,转速通常较低。

单侧翼滚动可以改善这种情况,改善之后,齿轮的质量是由旋转编码器(角度测量)评估的,而不仅只是距离。两个齿轮(一个是主齿轮)在与定轴的距离下运行,像在真实案例中一样。

单侧翼测量的现有技术发展水平
单侧翼齿轮测量仪器已生产应用于转子压缩机,蜗杆齿轮和锥齿轮。现有的测量系统的转速是很低的( 60/rpm,另外,噪声分析只是在较大的测量机器上实施。

需要解决的问题
合作伙伴需要一个单一的侧翼斜齿圆柱齿轮的测量系统,可以通过修改现有的齿轮测量仪器实现。这个项目,从硬件上看,对现有仪器有所修改,软件上看,设计了一个新的软件模块和新的装夹系统,以适应特定客户的需求,能够提供更高的转速( 600-800/rpm或更多,从而模拟有效地应用在现实的齿轮周期)和包括一个可选的噪声分析模块(在不同的频率)

减少的财政预算
作为一个对现有单侧翼齿轮测量系统的改善,所需的财政预算只有一个全新仪器设计财政预算的一小部分。设计能力是已经存在的,唯一需要购买的部件是噪音采集系统,特殊驱动器和高速强劲的组成部分。

益处
这种新的仪器将允许,在真实的运行状况下,评估斜齿圆柱齿轮的行为和噪声。

DRAFT PRE-PROPOSAL

Specific innovation objective

Development of a new high-speed gear measurement instrument for helical spur gears by single flank rolling method, with noise analysis

Double flank vs. single flank rolling method
Functional control of gears is typically made with 'double flank' (one gear and one master gears constantly in contact - measurement of instantaneous axis distance. This control method is the cheapest, as it uses one single length measurement device to measure istantaneous distance between gear axis, and is not effective, as gears usually have fixed mounting position. Rotation speed is usually low. An improvement is made by 'single flank' rolling, where the quality of gearing is evaluated by rotation encoders (angle measurement) and not just distance. The two gears (one can be master gear) work with fixed axis distance, as in real working conditions.

State of the art for single flank measurement
Single flank gear measuring instruments have been produced by partner nr.1 for rotor compressors, for worm gears and for bevel gears. Rotation speed for existing measuring systems is low (60 rpm) and noise analysis is implemented only in larger measuring machines.

Needs addressed
Partner number B requires a single flank measurement system for helical spur gears, which can be obtained by a modification of existing single flank measurement instruments for bevel gears. This project is a hardware modification of an existing instrument and the design of a new software module and new fixturing systems, to fit specific customer needs, capable of higher rotational speed (600-800 rpm and more, thus simulating effective application as in the real gear life) and including an optional noise analysis module (at different frequencies).

Reduced budget
Being an improvement of an existing single flank gear measuring systems, the required budget is only a fraction of the budget required for a completely new instrument design. Design capability is already existing, the only components to be purchased are the noise acquisition system and special drives and robust components for high speed.

Benefits

The new gear measuring instrument will allow to evaluate behaviour and noise of spur helical gear under true operational conditions.
