AmTech International bevel gear manufacturing services provide high precision crafting to maximize the functionality in powertrain / power transmission applications. Most specifically, motion and power between the intersecting shafts at a right angle.

Normally, their operation responsibility is to vary the drive direction within a power transmission system by ninety degrees. In addition, the precision ground teeth can be hypoid, spiral and straight. Learn more about the different custom types we produce.


 

Spiral Bevel Gears

A Spiral Bevel Gear are used to transmit power between shafts that are at a 90-degree orientation to each other. Also, these custom parts are engineered with precision teeth which have a unique curve and are oblique in shape. Spiral bevel gear teeth have one concave, one convex side, feature a curve and have a spiral angle. This spiral angle is located from the tooth trace and pitch cone, resembling a helix angle that is located in teeth of helical types.

Since spiral bevel gears are not offset, less sliding occurs within gear teeth. This results in a low temperature operation with more efficient functionality than hypoid gear types. Also, since there is a large amount of tooth surface this allows for greater interlocking during the rotation process. Because of this overall efficient operation, our custom spiral bevel gears are perfect for high speed, high torque transmission and power generation application types.

Capabilities:
- M2 to M15
- Maximum outer diameter is 600mm

 

Zerol Bevel Gears

Zerol bevel gears are basically the same type of product as spiral types. The only important variation is the spiral angle of the zerol bevel gear teeth are machined to zero. Also, the teeth are manufactured to have a gradual curve with both a convex concave side. Also this type of gear operates in a similar fashion to a gearbox's straight bevel gear, but are gear cut and finished with high precision equipment for extremely tight tolerances and surface finishing.
 

Straight Bevel Gears

Straight Bevel Gears have a straight tooth geometry, which if extended, would pass through the point of intersection of their axes. The teeth are produced from forged alloy steel for maximum strength and case hardened for increased durability.



Capabilities:
- M1.3 to M8.5
- Pitches as coarse as 2.5 diameter or as fine as 48 D.P.
- Maximum outer diameter is 216mm
- Ratios from 1:1 to 1:10
 

Anti-Backlash Miter Gears

The miter gear parts are used to minimize backlash, which is excess movement between the screw and nut. The specialized products are custom designed and configured in varying dimensions, with many selections teeth quantity, bore sizing and angle pitch. The anti-backlash category of gearing products are manufactured with high grade materials that include: stainless steel, aluminum, brass, polyurethane graphite, Delrin and rolled steel. This type of solution is most ideal for applications where extremely precise operation is required, such as in industrial automation, robotics and high capacity antennas.

These OEM geared parts can be supplied with custom material specs, bore dimensions, module, pitch and tooth styles.
