INTRODUCTION Running
gearing is a new type of mechanism designed to transform progressive motion into
rotary motion. The term "running gearing" is only a temporary name given
to the mechanism and the mechanism has not yet been given its definite name.
The running gearing is developed by Mr. V.A.Vorgushin, an engineer, a M.T.S. in
co-authorship with Mr. P.A. Shishkin, an engineer. The
technology of a running gearing makes it possible to withdraw from an engine its
main component - a crank mechanism and to improve the engine's parameters. The
technology of the running gear can be applied to all formerly manufactured engines,
equipped with crank mechanisms. Both modernization of the available stock of engines
and realization of new projects may become a very profitable business for a number
of years. THE
ARRANGEMENT OF THE RUNNING GEARING
The arrangement of the engine is shown in figure-1. The running gearing is made
up of toothed gear 1 seated on the engine shaft and being in constant mesh with
gear frame 2. Gear frame 2 is shaped consisting of two racks of equal length and
two toothed semicircles of equal radii. By this alternative the gear frame is
connected to piston 3 of cylinder block 5 via a motion unit of Z axis. For
fixing of the extreme left and the extreme right positions of gear frame 2 (fixing
of L dimension as per fig.) the device is equipped with a mechanism of dynamic
fixing (not shown in fig.1). A
mechanism of dynamic fixing is the cam-type. It comprises a cam itself and two
linear rests. The working face of the cam represents an arc of the sector of a
circle. The cam and toothed gear 1 are seated on the axis of rotation of the shaft
and they are stationary relative to each other. Linear rests are fixed along the
gear racks; working faces of linear rests are the surfaces facing the axis of
symmetry of the gear frame. COMPARISON
WITH CRANK-ENGINE The
comparison of the running gearing engine with conventional crank engine can be
done under four categories. They are 1.
Kinematics.
2. Gas dynamics.
3. Dimension and mass.
4. Production cost
