This involute calculator is the first all over world that you can input the parameters value and operate their fixed attribute for involute gear.

What"s even more surprising is that we can provide platform-cross application. That is to say you can use it on all most popular operate systems such as Windows, MacOs, Linux, Android. The application interface is shown as following pictures.

This calculator is base the gear standards ISO 21771:2007 and DIN 3960. Formulas are as following.

Equations according to ISO 21771:2007:

$$d=|z|cdot m_t=frac{|z|cdot m_n}{coseta}$$
$$m_t=frac{m_n}{coseta}$$
$$m_x=frac{m_n}{sineta}=frac{m_n}{cosgamma}=frac{m_t}{taneta}$$
$$m_n=frac{m_tcdot sineta}{taneta}$$
$$eta+gamma=90^circ$$
$$cosalpha _t=frac{d_b}rnjj5fl$$
$$tanalpha _n=tanalpha _tcdot coseta$$
$$d_b=dcdot cosalpha _t =|z|cdot m_tcdot cosalpha _t=frac{|z|cdot m_ncdot cosalpha _t}{coseta}=frac{|z|cdot m_n}{sqrt{{tan}^2alpha _n+{cos}^2eta}}$$
$$m_t=fracrhfrtnj{|z|}=frac{m_n}{coseta}$$
Equations according to $DIN 3960$:
$$m_b=frac{m_n}{sqrt{{tan}^2alpha _t+{cos}^2eta}}$$
$$d=|z|cdot m_t=frac{zcdot m_n}{coseta}$$
$$m_n=frac{m_bcdot coseta}{cosalpha _t}$$

Every parameter value should between a special region according involute gear theory and standard.

Involute Calculator can real-time check your input characters from keyboard and virtual keyboard. If the character input is wrong, calculator can show the error message in Information TextArea(for Android, the error message is shown by Toast).

There are 13 kinds of error message you would see.

bigger than the max limit: 100.

smaller than the min limit: 0.001.

more digits before dot: 2

more digits after dot: 4

Illegal dot here

more than one 0 in a real number

Illegal signal position here

Illegal 0 at the beginning of a integer number

Illegal character here: u

input is finished, you can not input any character more

minute part is bigger than 60

second part is bigger than 60

more angle second decimal digits: 3

We provide the Windows, MacOs, Linux and Android applications. You can install into your computers and smart phones. All install package and green-folder are integrated with jdk(Java Development Kit) 1.8, so you needn"t install any jdk. If you have install any other version 1.8, don"t worry about it, this application have nothing with the system-integrated jdk.

There are two kinds type app for windows, the "installing" and "green-soft", as it shown in following picture, you can choose one of them to experience calculating.

For the installing type, the installing process is a standard windows software installing process, you can install as the following steps. You can change install path in step 2.

We also provide to kinds type of install packages for mac os, the dmg package and the pkg package. I recommend you the first, because the dmg package is easy to drag the app file to Mac System Application Folder. like Fig

For the pkg package, just like the windows system install process, but you can not get the file path it installed to. So it is not a better way for this involute calculator. The pkg installing process is shown on Fig.

The operate interface is Chinese, but it is same to English one or other language and state.

As we known, there are many release version linux operate system, the most famous ones are ubuntu, red hat, debian, fedora and so on. The involute calculator can provide two kind of linux installation package, ded and rpm format.

These two format can be in many linux based operate system.

For ded package, you can install it use command:

dpkg -i involutecalculator-2.3.ded

More information of command dpkg is in https://help.ubuntu.com/lts/serverguide/dpkg.html

For rpm package, you can instal it use command:

rpm -ivh involutecalculator-2.3-1x86_64.rpm

More information of command rpm is in http://rpm.org/

The involute calculator for Android application is publish to the Google Play Store, you can install it via search InvoluteCalculator in Google Play. Fig is the Google Play . Also, you can visit the web page InvoluteCalculator to install it.

對于中國大陸的用戶，由于一些顯而易見的原因，您不能訪問幾乎全部的谷歌服務。為此，我們在國內酷安網發布了此應用。您可以訪問InvoluteCalculator安裝此應用。
For the Chinese mainland users, for some obvious reasons, you can not access almost all of Google services. To this end, we released this application in the 酷安網.

The mathmatic theory and Agorithm will be discuss and displayed in our involute calculator paper

The user interface have some parts, Fig.

If you click Logo Area, it will display the copy right information.

If you click Develop Info icon, it will display the developer information.

In setting dialog, you can change the operator name, interface language and system log.

Iterms will take effect after you restart this application

The web application is same to desktop application for user.

For a common test case, $z=24,m_n=5,m_t=5,m_x=29,m_b=5,alpha_N=20^circ,alpha_T=20^circ,$$beta=10^circ,gamma=80^circ,d=122,d_b=115$

We look forward to your feedback and Suggestions about this Involute Calculator if you have some questions or find some bugs about this software. You can email an issue to Prof. Dr.-Ing. Prof. h. c. Frank H?rtig and Xiaozhong GUO.
