The production of gears is an important business that supplies vital parts and equipment for engineering. Manufacturers of these use specialized processes and tools for their creation. Here are some important terms related to this industry.
Grinding – This is a cutting method where gears are formed and shaped by grinding wheels and tools. Manufacturers use this method primarily as a finishing operation.
Spur – This is the most straightforward design. They are a disk that has teeth projecting out in a radial fashion. They are not straight sided, but each groove is paralleled to the rotation axis. As each tooth engages, it has an impact on all corresponding teeth at once. This can be problematic because of the noise it creates.
Helical – The teeth on these are at an angle, allowing them to interact gradually. These are commonly used in automobile transmissions and other machines because they engage quietly and gradually, reducing noise.
Bevel – These are used when the shaft’s rotation needs to be altered. Two bevels may be 90 degrees apart. Straight ones are similar to spur in that all teeth are impacted at once, whereas spiral ones act more like the helical style in that they engage gradually. These are commonly used in many types of industrial machines.
Worm – These are put into use when large gear reductions are needed. The angle of it makes it useful in conveyor equipment as a braking mechanism because the worm will not allow itself to be turned.
Hobbing – This is a process in which a hob cuts teeth into a blank. The blank and the cutter rotate at the same time allowing the shape of the hob to be transferred. The hob must go around one complete time for each tooth.
When mechanical engineering firms and other companies need standard or custom gears, they buy directly from the manufacturer. Manufacturers that sell gears and provide gear cutting can cut new gears from a variety of materials. They use special lathes, milling cutters, tools, and machines to carve and turn gears from steel, plastic, and other durable materials.
Other services may include milling, turning, grinding, cutting, and honing. Gears help machines move, by employing a turning movement coupled with friction. Grooves in the gears fit into other components, allowing for a fluid motion. When they get stripped, new ones are needed. Manufacturers provide sales of gears such as helical, worm, bevel, and spur.
Gears of all kinds are needed in anything from trains and cars to military and commercial aerospace industries. They come in a variety of shapes, sizes, and styles, such as flat, hub, and internal. Companies in this industry may offer services ranging from gear shaping and turning to milling and surface finishing. In addition to gears, they may also sell accessories such as custom gear boxes, automatic machines, and precision tool room lathes.
Different vendors and dealers may specialize in gears for different industries. One may focus on services for the power tool business or automotive industry, while another may focus on the medical instrument and equipment industry. These companies often have full color catalogs on their web sites of all products, along with outlines of all services that potential customers can check out.
Customers can also find out more on the tools and lathes involved in the industry by contacting manufacturers directly. Listings appear online and in the phone book for gear cutting manufacturers.
