EC gearing, a new kind of toothed engagement — is a fundamental resource and energy saving development in the field of machine-building industry

A new kind of gearing called eccentrically cycloidal (EC) is developed,
on its basis the manufacture of almost any type of gearbox is possible
(cylindrical, planetary and bevel EC-gearboxes, and also
rack-type EC gears for mechanisms with rectilinear motion).
The new kind of gearing is asserted by 7 patents of Russian Federation.
International applications are filed.

Advantages of EC-gearing in comparison with analogs

Gearing type

Gear ratio U

Efficiency factor

Relative mass factor, kg/N*m

Involute gearing (external)	1-8	0,93-0,97	0,04-0,07
EC-Gearing (external)	1-40	0,9-0,99	0,005-0,01
Gearing with intermediate rolling bodies	8-40	0,4-0,8	0,01-0,02
Warm gearing (globoidal)	10-80	0,4-0,8	0,24-0,06

Figure shows the comparative dimensions of pinions with EC gearing and involute gearing with the same parameters (U = 9, equal loading torwue).

Several times reduction of mass and overall dimensions;
Increased gear ratio U in one stage up to 30
(in the involute gearing U<= 8);
It is allowed to increase misalignment and center-to-center clearance in the EC gearing 5-10 times compared with functioning standard parameters for the involute gearing without loss of force characteristics in the enegagement;
Efficiency in the EC gearing approaches the rolling efficiency 99,9% for Кfr = 0.075, since the meshing point is in the pitch point.

Our company has developed a new heavily transmitting module «Cyclo-TM» , instead of serially produced by PCR 320. At the same dimensions of our design modules transmits more torque and has an increased service life. Looking for investors.	When you visit Tomsk economic zone, the Deputy Minister Ministry of Emergency Situations Alexander Chupriyan see our products. Alexander Chupriyan expressed interest in the application of gears with the EC-gearing in the technique used in emergency response.	Prepared for shipment the next batch of gears with the EC-gearing main gear truck BelAZ 7555. At the moment, negotiations are under way to organize production this gear in Mezhdurechensk. At the same time developed design documentation for the main gear trucks BelAZ 30 tons and 90 tons.	Our company has developed a promising solution to the use of EC-gearing in the Top gear drive for drilling rigs. This solution has several competitive advantages over existing sravniniyu Russian and foreign counterparts. We invite you to cooperate with investors.
