Improper contact pattern is one of the most relevant root causes for premature gearing damage. In case of well designed gearboxes, pinion modification shall ensure that there is always a smooth transition between load carrying and non-load carrying areas of the flanks. Accordingly, edges of the flanks and the tips of the teeth shall not be in contact at regular loads, just providing some reserves for extreme peak torque.
As contact pattern is influenced by elastic deflections of the system, its verification has to be conducted at regular load conditions - preferably on a test rig, alternatively during regular operation. One option is application of contact dye which will be removed where metallic contact appears and otherwise can remain in the gearbox until end of service life. The strong point of this method is that it can easily be applied to gearboxes that are already installed and thus can even detect possible influences by the installation itself.
Apart from that, such inspection can be part of the acceptance protocol, which is highly beneficial in case of small series of industrial gearboxes.

EELPRAAX-130 "Nadeshda"
After recently introducing EELPAX and EELPRA which are dedicated to either axial or radial loading of bearings, this machine type EELPRAAX-130 combines the benefits of both machines by their two hydraulic cylinders per test station.
Accordingly, test rigs type EELPRAAX can universally test any kind of bearing at any combination of axial and radial loads while EELPRAAX-130 suits to bearings up to 130 mm outer diameter.

EELPRA-130 "Sissi II" This machine is mainly used for endurance testing of deep groove ball bearings, cylindrical roller bearings and any kind of radial bearings up to 130 mm outer diameter while its two test stations allow for simultaneous testing of up to eight specimens on two shafts. Therefore, a typical application of this test rig is part of incoming quality inspection by which eight randomly picked samples are subjected to very demanding testing conditions leading to approval of the related container if each sample achives e. g. two times calculative lifetime.

Bearing test rig EELPAX-200 "Rami II"

This machine is mainly used for endurance testing of tapered roller bearings, angular contact ball bearings and any kind of thrust bearings up to 200 mm outer diameter. Within EELPAX series, the EELPAX-200 is the biggest test rig that can be operated by one person without a crane.

By its two test stations with completely independent oil circuits, one can simultaneously carry out two test runs on in total four specimens while load, speed, oil temperature and oil flow rate can be varied in wide ranges.

Overseas shipment of a brand new test rig type EELPRA-130.
This test rig is suitable for lifetime testing of radial bearings up to 130 mm at a broad spectrum lof loads, speed and lubrication conditions. Its main purpose will be incoming inspection of especially deep groove ball bearings.

Just started testing of worm drives using steel worms and steel gears on an electrical gearbox embracement test rig. These test runs are part of a research project which shall lead to substitution of bronze by steel in worm drives in order to reduce dependence on expensive copper alloys, increase power density and decrease consumption of electricity.
