Sometimes projects call for certain types of gears that just can not be found in the typical marketplace. If you should be faced with this not too uncommon problem, custom made gears can be ordered from gear manufacturing companies. But, in order to buy custom gears, you need to know some of the basics of pinion gears (circular gear used with a rack strip which is toothed), splined shafts, and the like.
Gear manufacturing companies can help you to get any job done that calls for gears, if you know what it is you are looking for. One thing you will have to keep in mind when ordering your gears will be material. Many people prefer cast iron. In fact, this is the most popular material for bevel gears due to its durability. It does not wear down very easily at all. Cast iron gears will be sure to pass the test of time.
When it comes to bevel gears, it is important to know how many teeth you will want. The difference in the amount of teeth will dictate many aspects of the performance of your gear. How ever many teeth the bevel has will determine the mechanical advantage to be changed as you see fit.
Hypoid gears are a type of bevel gear, but they are a bit different. Gears of this nature resemble bevels, but their shaft axes do not intercept. This can add some freedom to a project, creating a somewhat more diverse gear.
In some projects, high torque will be a necessity. Gear manufacturing companies usually offer worm sets, which are great for transmitting that high frequency torque you are looking for.
Before approaching gear manufacturing companies, it is important that you know your project inside and out. You will be a much more satisfied customer if you contact gear manufacturing companies knowing just what you have in mind.
