Title Rotator
mechanism The problem the inventor(s) wanted to solve The main aim was to create
a simple mechanism for the coupling of two shafts where the direction of
rotation of the driving and driven shafts can be the same or opposite and
their angular velocity is always the same. Description. This rotator mechanism is
suitable for the coupling of two shafts that are in parallel to each other or
in any angular position with respect to each other and, where the angular
velocity of the driving and driven shaft is always the same, while their
direction of rotation can be arbitrary. Presentation. This mechanism
is suitable for the transmission of the rotary movement from one shaft to an
other that are in parallel to each other or in any angular position with
respect to each other, with the same or opposite direction of rotation. Its
construction differs from the usual drives, since,
it does not contain gear or flexible, deformable components. It does not
change the drive ratio, but its construction enables the branching of the
power transmission chain. The precisely guided arms make also possible the
constant power transmission even if no oil lubrication is used. Its
structural design is shown in the perspective diagram. At the extreme
ends of the shafts there are shaft coupling heads to which moving arms are
connected. These moving arms, at the driving shaft end, convert the rotary
movement into vector components and then, by moving periodically the two
shafts found in the centre part of the mechanism, the rotary movement is
rebuilt again at the driven shaft end. In this
mechanism the efficient co-action of the arms and the inner shaft results in
the synchronous rotation of the coupled shafts and, when starts the rotation
of one of the shafts then the other shaft follows its rotary movement with
the same angular velocity and, depending on the construction layout, in the
same or opposite direction. The mechanism provides the
highest efficiency if the rotating and moving components are supported in
bearings and the rotary parts are balanced that can also be realised without
any difficulty. Application This rotator mechanism can
be used in the machine and vehicle industry. It is suitable to replace gear
type drives and cardan joints that are permanently
built in (fixed position) ones. Advantages The construction has a low
friction, noiseless operation, low lubricant requirement and a higher shaft
angle range as that of the cardan joints and, at
the same time, the driving and driven shafts have the same angular velocity
in every moment. Its construction is simple and, thus, it can cheaply and
easily be manufactured and it can be dimensioned for versatile use. Stage of development. The prototype development
is in course. Documentation available: The complete technical
