The engine with no crank shaft is temporarily known by a
name called ‘running gearing’ engine. The technology of running gear can be
applied to all formerly manufactured engines equipped with crank mechanism.
This seminar deals with the arrangement and working of the engine and also its
comparison with conventional type of engine. The comparison result shows that
running gearing engine as much improved engine parameters than conventional
crank engine. 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 obvious advantages of running gearing engines – a steep
rise in torque of the shaft and a proportional growth of economical efficiency
- will promote their fast and wide spread. The advancement of the process will
be influenced by the fact that the current stock of combustion engines can be
quite easily updated for a running gearing mechanism.
The extensive
use of engines of this kind in transport and in industry can solve the problem
of power (energy) resources shortage for a long period in many countries. Also,
it is reasonably to speak about the essential prerequisites to the reduction of
world oil prices, as the fast growth in the efficiency of generation of a power
unit reduces the dependence on purchasing of power resources in the same
proportion. Taking into account the fact that fuel filling tanks of
transportation facilities are invariable, it can be noted that the use of
running gearing engines adequately increases the transportation range without
refueling. This is especially essential for air and sea transport.
In the process of rotation of toothed gear 1 (arrowed line)
being in mesh with the left gear rack of frame 2 as per Fig. 1 of the sketch,
piston 3 with gear frame 2 is moving upwards. At the moment when toothed gear 1
is going from the section of the left gear rack to the section of the toothed
semicircle of frame 2 motion velocity of piston 3 is slowing down abruptly,
falling off to zero in the point, when the vertical axis of symmetry of gear
frame 2 is in alignment with the diametric line of toothed gear 1. This
momentum corresponds to the upper dead centre (UDC) for piston3.
Concurrently, with the transfer of toothed gear 1 from the
gear rack section to the toothed semicircle section of frame 2, the fixing
mechanism takes frame 2 off the rest audits displacement is initiated to the
left under the effect of cross-axis component force, exerted in the engagement
of toothed gear 1 with the toothed semicircle of frame 2. Completely the cross
motion is finished at the moment of toothed gear 1 transfer from the section of
the toothed semicircle to the section of the right gear rack of frame 2. At
that very instant the teeth of gear 1 are wholly dropping out of mesh with the
left gear rack and are engaging with the right one. The fixing mechanism
locates the position of the frame relative to the toothed gear according to L
dimension. From the above indicated UDC point the movement of piston 3 with
gear frame 2 is initiated to the opposite direction, i.e. downwards accompanied
by a drastic linear velocity increase from zero.
The process of
further rolling of the gear over the gear rack with the change-over to the
upper toothed semicircle and then from it to the left gear rack, and all the
processes coming about in this case (the process of fixing and releasing of the
gear frame) are similar to those described. As a result as in a crank engine,
the complete double piston stroke is carried out in one complete revolution of
a toothed gear.
