Introduction

Gears are machine elements used to transmit rotary motion between two shafts, normally with a constant ratio. The pinion is the smallest gear and the larger gear is called the gear wheel.. A rack is a rectangular prism with gear teeth machined along one side- it is in effect a gear wheel with an infinite pitch circle diameter. In practice the action of gears in transmitting motion is a cam action each pair of mating teeth acting as cams. Gear design has evolved to such a level that throughout the motion of each contacting pair of teeth the velocity ratio of the gears is maintained fixed and the velocity ratio is still fixed as each subsequent pair of teeth come into contact. When the teeth action is such that the driving tooth moving at constant angular velocity produces a proportional constant velocity of the driven tooth the action is termed a conjugate action. The teeth shape universally selected for the gear teeth is the involute profile.

Consider one end of a piece of string is fastened to the OD of one cylinder and the other end of the string is fastened to the OD of another cylinder parallel to the first and both cylinders are rotated in the opposite directions to tension the string(see figure below). The point on the string midway between the cylinder P is marked. As the left hand cylinder rotates CCW the point moves towards this cylinder as it wraps on . The point moves away from the right hand cylinder as the string unwraps. The point traces the involute form of the gear teeth.

The lines normal to the point of contact of the gears always intersects the centre line joining the gear centres at one point called the pitch point. For each gear the circle passing through the pitch point is called the pitch circle. The gear ratio is proportional to the diameters of the two pitch circles. For metric gears (as adopted by most of the worlds nations) the gear proportions are based on the module.

m = (Pitch Circle Diameter(mm)) / (Number of teeth on gear).

In the USA the module is not used and instead the Diametric Pitch d pis used

d p = (Number of Teeth) / Diametrical Pitch (inches)



Profile of a standard 1mm module gear teeth for a gear with Infinite radius (Rack ).
Other module teeth profiles are directly proportion . e.g. 2mm module teeth are 2 x this profile


Many gears trains are very low power applications with an object of transmitting motion with minium torque e.g. watch and clock mechanisms, instruments, toys, music boxes etc. These applications do not require detailed strength calculations........

How To Pick The Best Web Hosting Company

There are a lot of Web Hosting Company. First you should choose Good and Reputable company, then you should Filter that to the Best. Here is the criteria to pick the best Web Hosting Company.

Back End/Network Operations Centers
This is where your accounts are actually housed. Sometimes a hosting provider will lease a part of a larger network and sometimes a hosting provider will develop their own. It is important to find out what kinds and how many fiber optic connections the NOC has. Make sure there is plenty of redundancy built in. Make sure the NOC is managed 24/7, even on holidays. Make sure there are fire suppression systems in place. Last but not least, ask about security. Make sure there are plenty of security measure in place.

Customer Service
Are they friendly? Do they answer their telephones? Are you put on hold and if so, for how long? If you have to leave a message, do they respond quickly? Does the rep on the other end know what they are talking about? Look at their network page and see if they have reports of down time or issue statements about problems.

Technical Support
How long does it take to get questions answered and tasks performed. Send a test support message and gauge the response times. See if they offer 800 toll free support.

Ticketing Systems
Do they have a ticketing system that tracks performance times. This is key. If a hosting company has this, they are serious about improving internally.

Domain Names
Do they offer domain name sales? This can help to consolidate your vendor costs. See about getting a discount on domains if you are buying in bulk on a monthly basis.

Branding You
Does the hosting provider offer branded support? As you grow, you will need to expand and see if the hosting provider will set you up with your own technician in your company name. Do they offer branded control panels and name servers? You need these tools to grow. Find out how easy it is to set these features up for your own account.

Scalable Discounts
If you are growing at a rapid rate, ask for better pricing and discounts. It is ok to ask. It’s even better when you get it and will
reduce your overhead.

Financial Overview
Is that particular company in the red of black? Do they have a good cash flow? How fast is the host growing and can they handle the growth? What are they doing to grow and maintain the customer service level you expect. Are they near a buy out or planning

An Introduction to Domain Names

Simply put, a domain name is a “front” – they are word sequences users enter in their browser’s location bar to visit your site, but are not a Web site’s true address.
Domain names are attached to DNS (Domain Naming System) servers, which are used to translate numeric addresses (known as IP, or Internet Protocol, addresses) into words. Each site you visit on the net has a numeric IP address behind its name, which represents the site’s true address on the Internet.
Domain names are typically categorized by their extension, which is their identifying code. The three most popular types of Top Level Domains (TLDs), which are domains that are not
associated with a country, are:
.COM: Short for .commercial. Domain names with the .com extension are by far the most popular, and can be purchased by any individual or business. .
.NET: Short for .network, this domain extension was originally designed to be used by technical Web sites. However, domains using this extension can be registered by anyone.
.ORG: Short for .organization. Originally designated for non-profit firms and any other organizations that did not fit under the .com or .net extension, any individual or business may now register a .org domain name.
Country Level Domains
Domain names can also be assigned using country extensions. Each country has its own domain extension; Canada, for example, is .ca, while Japan has been assigned .jp. Most countries have specific rules surrounding exactly who can register domains using their extension and for what purpose; it’s therefore important to look before you leap.
Alternative Domain Names
The Internet Corporation for Assigned Names and Numbers (ICANN), the organization responsible for the administration of TLDs worldwide, recently approved several new extensions that are not specific to any country. These are:
* .areo
* .biz
* .coop
* .info
* .museum
* .name
* .pro
Each has been designed for a specific use, and is accompanied by certain restrictions. You can find more information about these TLDs here: http://www.icann.org/tlds/
Other Domain Extensions
In searching for your domain name, you may encounter Web sites offering extensions like .xxx, .free and .mp3. These are not true extensions endorsed by ICANN; rather, they rely on software solutions to guarantee their accessibility to users. Because ICANN has not approved any of these extensions, however, users that do not have the correct software cannot access sites using these names; therefore, they should be used for supplemental purposes only.
Although .com, .net and .org are typically the most visible and talked-about extensions, they are not the only ones available for use. From a functional perspective, country-level domains work just as well as any TLDs, and alternative extensions work just as well. Therefore, don’t necessarily settle for a mediocre TLD when you can get a better one using a different extension.
