Plastic bevel gears, sometimes referred to as bevel pinions, are gear systems featuring conically shaped teeth and are made from various plastic materials. These gears are designed to transfer rotational motion between intersecting shafts at an angle.
The Plastic Bevel Gear capacity of welle manufacturers including process, material, weight and size is listed as follows:
✧ Plastic Process: Insert& Overmolding, Double Injection molding, Plastic Gear Molding, Prototype Molding, CNC Machining
✧ Plastic Material: Nylon, Acetal/POM, ABS/PC, U-PE, PEEK, etc
✧ Gear Quality: JIS 2( B 1702),JIS N6(B 17020-02),AGMA 12 (390.01~03);
Similar to miter gears, WELLE bevel gears have straight teeth and a conical profile for transmitting motion at a right angle. Unlike miter gears, one of the gears (sometimes
called a pinion) is smaller than the other. Combine a pinion and gear for right-angle speed reduction at ratios ranging from 2:1 to 4:1.
The bevelled gear drive serves to transfer rotary motion and torque, and the power transmission takes place through the bevelled gears. We offer machining and injection molding of straight bevelled gears.
Reduce Speeds where noise, and frequent lubrication are a concern, compared to metal gears, these nylon gears run more quietly, won’t rust, and don’t need to be lubricated. Because they’re self-lubricating, these bevel gears are commonly used in food machinery. they should not, however, come in direct contact with food or chemicals that will come in contact with food.
A complete set consists of a gear and pinion (sold separately). For a gear and Pinion to mesh correctly, they must have the same pressure angle, module and face width. plastic pinions can also be mated with metal gears, and plastic gears with metal pinions.
Speed ratio is the ratio by which shaft speed is reduced when transferring motion from pinion to gear, to increase shaft speed, transfer motion from gear to pinion. Changing shaft speed also changes torque: as speed decreases, torque increases.
