D gears catalog on inter 167 Finding useful 3D catalogs on inter Today on inter the information is structured into web pages. Almost all the panies in the world have web pages in order to offer more information about their products. There are 3 ways to search: 1 to find a pany into some specific engineering fields. If the name of pany is known usually the site is。 （ names） . (ex: SKF has ). If is not, an easy way is to use a searching site as google ( ) and as keywords the pany name。 2 to find some panies witch have similar products it is remended to use searching site as google and keywords technical words witch describe the product. For example to find bearing panies it can be use: keywords like “bearings”。 “ball bearings” etc.。 3 to find some specific products (standard or not) for a specific engineering field it is remended to use dedicated portals. A portal is a site which contains information and links to specific sites for a domain. (ex. On inter in the engineering fields the panies presents their products structured in catalogs. There are two types of catalogs on web. One is in wellknown format PDF (portable document format). To find catalog of this type it is remended for searching to use, after specific keywords, the acronym “PDF”. The advantage using a pdf catalogs is that all the needed information about a product is presented into single file, which can be printed. The other is interactive online catalogs which have some advantages like: 1 to find all information for a product (including in pdf format), 2 online calculus software, 3 the product can be directly implemented into CADCAMCAE software. To find such types of catalogs it is remended to use keywords as “3D catalogs online” in bination with technical keyword. For example to find a gears catalog 3D on line it can be use for searching the next string: “gears 3D catalogs online” Using 3D ponent catalogs In figure 9 is presented a screen capture for the results of 3D gears catalog search. With red arrow is marked possible inter address for 3D catalogs. In red rectangle is marked the address for interactive catalog presented in figure 10. In figure 10 is presented a portal for technical products which offers free 3D and 2D catalogs. As example it is presented a catalog wheal used in design of gear presented in figure 5. For selecting a wheal in this catalog it has 168 to specify all the necessary parameter: Pitch。 . Of Teeth。 Style。 Class。 Angle Degree。 Size。 Width。 Dia。 Dia. ( N/a= Hubless). Finding interactive online catalog . Interactive online catalog for gears In figure 11 is presented all the characteristics available in this catalog ( ) for selected wheal as technical characteristics。 prices。 available file formats for direct implementation into CADCAMCAE systems. Wheal characteristics For 3D model it was selected a step forma。
