Elliptical gears

Elliptical gears are mostly needed by manufacturers of automatic machines, especially in the printing and textile industry. Sometimes the rotation speed of a shaft, pusher, blade, sealer needs to be changed within the same turn. Elliptical gears actually change a rotary motion with steady speed into a rotary motion with variable speed within the same turn. The degree of speed variation depends on the distance between the ellipse focuses. And in all those cases in which the speed of the driven shaft needs to be
changed within the same turn.

Different and variable ratios are available with properly used sets of three and four-gears for automatic machines handling different product sizes. Elliptical gears can be of different materials according to the Customer's needs: steel, bronze, nylon and bakelised fabric. Proper instruments ensure a good rolling of
the pairs: gears are also checked after being heat treated if cementation and hardening or induction-hardening on gear teeth is required, so as to remove possible deformations. Elliptical gears for high rpms can also be balanced, on Customer's request. All gears have suitable reference marks for a proper assembly as they need to be assembled with a certain timing. Until now, elliptic gears have not been widely used. This was mainly due to the difficulty of making them. We think that the design and engineering of our elliptic gears has reached a good quality standard. We already supply several world famous companies with our elliptic gears regularly.
