Evoloid gears in general

New technology:
Gears which consist of less than five teeth are called evoloid gears. To realise those helical gearing has to be used.

We show you different types of gears in which the pinion has only one tooth. Those can be used for transmission into slow movement as well as in fast transmissions. Therefore you get an immense scope of increasing the transmission.
We can calculate, design and produce those evoloid gears in chipping methods and in mass production methods.



Advantages of evoloid toothing

Gears to reduce the rotational speed: An example shows the advantages of a very common transmission for an actuator in platine type with transmission i=1000:1

Currently in industrial applications gears with common toothing achieve transmissions of around i=4:1, if you for example need a ratio of i=1000:1 you need minimum 5 stages and therefore 10 wheels and six axis (4 potentized by 5 = 1024 )
Evoloid toothing gives us the opportunity to use pinions with only one tooth, so if the tooth number at the hollow wheel stays the same (60), the transmission increases to i=60:1. So we cut the number of needed stages in half, also shrinking the overall dimensions.
In several applications we built evoloid toothed gearings with slow transmissions and conducted many of our customers into serial production.

Gears to increase the rotational speed:
Along the lines of an example for a not so common actuator with a transmission ratio of i=1:200

Here common wheel also limitate to i=1:4, therefore we need 4 stages with 8 wheels and 5 axis ( 4 potentized by 4 = 256).
By using evoloid gears with i=1:60 we can again reduce to 2 stages and only need 4 wheels and 2 axis.
By increase of the rotational speed it will also be possible to achieve transmissions up to i=1:100. In several applications we built evoloid toothed gearings with fast transmissions and conducted many of our customers into serial production.
