herringbone gear

All kinds of cylindrical gears can be manufactured using 5-axis technology. A good example are herringbone gears used in applications where the rotating speed of the gear is really high, for example in the reduction gear of a gas turbine. To achieve a smaller housing with cheaper and simpler bearing arrangements, using the 5-axis technology is a superior solution. And ATA Gears can offer you that.

Comparison with the traditional method makes it clear why: For example, with a 20 mm teeth module, the wheel or disc grinding is around 0.5 m diameter, so it needs a big space to exit the tooth gap. And that’s definitely a big drawback with the traditional method.

Now, with the 5-axis method, there’s no need to leave a space at the point where the tooth direction changes, so we can manufacture a considerably smaller and lighter gear. For gear designers this means new opportunities and savings in material costs. That’s right, producing the gear set needs less energy and raw material. To top it off, smaller size provides the same output.

Less energy and raw material are needed.

No size limits

With ATA Gears’ 5-axis technology there’s just no limit on size with any gear wheel type: up to 3 100 mm diameter is feasible. Likewise pinion shafts up to 1 000 mm diameter. So it’s definitely a preferable production option for non-serial gears in specific applications or service projects. We can produce all non-standard tooth geometries. There is just no upper limit to the module and the tooth can be in very tight spots, even attached directly to the axle.  And again, using the 5-axis method, you also get a much more durable tooth root than with conventional methods. All this and highly competitive delivery times. No special tooling is required as with conventional machines.  Well worth thinking about?
