ROLLER, IN PARTICULAR TRACK ROLLER OR CARRYING ROLLER FOR
CABLEWAY SYSTEMS
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the priority, under 35 U.S.C. ยง 119, of Austrian patent
application AT A155/2012, filed February 6, 2012; the prior application is herewith
incorporated by reference in its entirety.
BACKGROUND OF THE INVENTION
Field of the Invention:
[0002] The present invention relates to a roller, in particular a track roller or a carrying
roller, for use in cableway systems. The roller has a cylindrical tubular piece located
radially on the inside, two annular bearings which are located radially outside the
tubular piece and at an axial distance from each other, and a roller body which is
located radially outside the annular bearings and is embodied by a track ring and by
two flanged disks located to the sides thereof.
It is known in conveying systems having vehicles which are movable along
carrying cables or along guide rails to supply the electric devices located in the
vehicles with electric energy by means of accumulators. In that case, the
accumulators have to be charged up in the stations of the conveying systems, but this
necessitates a large technical outlay in the case of conveying systems in which the
vehicles are permanently in movement. In addition, as electric apparatuses increase
in size, the accumulators are required to have increased capacity. For this primary
reason, it would be desirable to produce the required electric energy by way of the
movement of the vehicles, wherein the electric apparatuses and systems are supplied
directly with current and the accumulators are charged up.
United States Patent Application Publication US 2008/0276826 A1 and its
counterpart European patent EP 1 992 539 B1, which are commonly assigned with the
instant application, described a cableway system in which cable cars are moved along
a carrying cable and the running gear of the cable cars is equipped with at least one
friction wheel which rolls along the carrying cable and which is embodied with a
generator which is operated by the friction wheel. This makes it possible, by the
movement of the cable cars along a carrying cable, to generate current by means of
the generator located on the running gear, the current being used to supply the electric
devices and systems located in the cable cars directly with current and to charge up
accumulators.
However, that known device necessitates considerable extra technical outlay
since the running gear of the cable cars additionally has to be embodied with at least
one friction wheel.
United States Patent Application Publication US 2010/0180792 A1 and its
counterpart International Patent Application A1 describe a
conveying system which has vehicles provided with track rollers, wherein one of the
track rollers is embodied with a generator. In that case, the generator is located on the
outside of the track roller, and the rotor of that generator is rotated simultaneously with
the track roller.
However, that known device is disadvantageous since it has be to be taken
into consideration in the structural configuration of the entire conveying system that the
vehicles are embodied with at least one track roller from which a generator protrudes
in the axial direction. In addition, the generator which is located on the outside of the
track rollers has to be protected against interfering influences, in particular against the
ingress of moisture and water.
There is furthermore the fact in the case of cableway systems that the carrying
and conveying cables for the cable cars and the traction cables for cable cars moving
along carrying cables are guided in the region of supports via carrying rollers which
are rotated by the movement of the carrying and conveying cables and of the traction
cables and that electric devices, such as transmitters, receivers, control apparatuses,
measuring apparatuses etc. for which an electric supply has to be provided, are also
provided on supports. Up to now, those electric devices have been supplied with
current via electric lines that are laid to the supports. As an alternative thereto, the
supports are provided with solar collectors and accumulators for effecting the supply of
electricity.

embodied by a track ring and by two flanged disks located to the sides thereof, in that
the roller is embodied with an annular electric generator which is located within a
cavity surrounded by the roller body and the two annular bearings.
In a preferred embodiment, the electric generator is formed by an annular
stator with at least one induction coil and by at least one permanent magnet which is
movable in relation to the stator, wherein the annular stator, which is carried by the
tubular piece, is located radially outside the tubular piece and in the axial direction
between the two annular bearings, and the at least one permanent magnet, which is
located radially outside the stator, is connected for rotation to the roller body, which is
rotatable in relation to the tubular piece.
In this case, the at least one permanent magnet can be located on a carrying
ring or permanent magnets can be embodied as a carrying ring, wherein the carrying
ring is fastened to the roller body. Furthermore, the annular stator can be located on
an annular carrier arranged on the tubular piece.
According to a further preferred embodiment, the roller body is embodied in
two parts and the two parts of the roller body surround the annular cavity in which the
annular electric generator is located.
Other features which are considered as characteristic for the invention are set
forth in the appended claims.
Although the invention is illustrated and described herein as embodied in a
roller, in particular track roller or carrying roller for cableway systems, it is nevertheless
not intended to be limited to the details shown, since various modifications and
structural changes may be made therein without departing from the spirit of the
invention and within the scope and range of equivalents of the claims.
The construction and method of operation of the invention, however, together
with additional objects and advantages thereof will be best understood from the
following description of specific embodiments when read in connection with the

DETAILED DESCRIPTION OF THE INVENTION
[0024] Referring now to the figures of the drawing in detail and first, particularly, to
Fig. 1 thereof, there is shown a section of a cableway system with a carrying cable 1, a
traction cable 1a and a cable car 2. The cable cars 2 of the system are movable along
the carrying cable 1 by way of the traction cable 1a. The cableway cars 2 are
embodied with track rollers 3 mounted on a running gear 21, wherein the running
gear 21, to which the cable car 2 is fastened by means of a carrying rod 22, is
movable along the carrying cable 1. The carrying rod 22 is pivotable on the running
gear 21 about an axis oriented approximately at a right angle to the direction of
movement and approximately horizontally by means of a joint 23. The running gear 21
is embodied with a clamping device 24 by way of which the cable car 2 can be coupled
to the traction cable 1a.
Fig. 2 illustrates a support 11 of the cableway system, at the upper end of
which support carrying rollers 3a are located, said carrying rollers being arranged on
rockers 12 and via which a carrying and conveying cable 1b is guided. The carrying
rollers 3a are rotated by the movement of the carrying and conveying cable 1b. A
maintenance platform 13 is furthermore located at the upper end of the support 11.
The track roller 3 and carrying roller 3a respectively illustrated in Fig. 3 and
Fig. 3A comprises a cylindrical tubular piece 31 which is located radially on the inside,
is embodied with steps on the radial circumference thereof and onto which two annular
bearings 32 located at an axial distance from each other are placed, the bearings
being assigned sealing lamellae 32a and being kept in the axial positions thereof by
means of spacer rings 32b. The roller body 33 is located radially outside the two
annular bearings 32. A track ring 34 is located radially outside the roller bearing 33,
and respective flanged disks 36 are fitted to the sides of said track ring with the
interposition of elastic rings 35. The flanged disks 36 are kept in the position thereof
on the roller body 33 by securing rings 37. The roller body 33 consists of two roller
body parts 33a and 33b.
Electrically insulating sleeves 31a are inserted into the tubular piece 31 at both
ends thereof and a central sleeve 31b is inserted in the central region thereof, which
sleeves 31a and 31b consist of a plastics material. The track ring 34 is produced from
a rigid elastic plastics material. The elastic rings 35 serve to press the two flanged
disks 36 against the securing rings 37. A screw 30 which serves for positionally
securing the track ring 34 is furthermore located in the roller body 33.
Between the tubular piece 31 and the roller body 33 there is an annular
cavity 30 which is formed by the two annular bearings 32 being located at an axial
distance from each other, thus forming an annular space 30a therebetween, and by
the roller body 33 being embodied in the central region thereof with an annular
recess 30b. The annular cavity 30 contains a generator 4 which consists of an annular
soft iron core 41, induction coils 42 located on said soft iron core and permanent
magnets 43 assigned to the latter. The induction coils 42 are connected in series.
The soft iron core 41 is fastened on a carrying ring 44 which is likewise placed onto
the tubular piece 31. The permanent magnets 43 are fastened on a carrying ring 43a
or are embodied as a carrying ring 43a, wherein said carrying ring 43a is likewise
inserted into the cavity 30 located within the roller body 33 and is coupled for rotation
to the roller body 33.
In this case, the soft iron core 41 together with the induction coils 42
constitutes the stator of the generator 4. By contrast, the permanent magnets 43,
which are rotatable together with the roller body 33 in relation to the tubular piece 31,
constitute the rotor of the generator 4. A line 42a which is led out of the roller 3, 3a is
connected to the induction coils 42. The roller body part 33a is embodied with a
pressure compensating element 45 through which moisture located in the cavity 30
can escape out of the latter.
The track roller 3 or carrying roller 3a is fastened to the running gear 21 of a
cable car 2 or on a rocker 12 which is located on a carrying support 11 by means of a
bolt 5 passing through the tubular piece 31. By this means, the tubular piece 31 and,
by means of the latter, the stator of the generator 4 are arranged in a manner mounted
on the framework, whereas the roller body 33 and, by means of the latter, the
permanent magnets 43 are rotatable in relation to the tubular piece 31 by means of the
annular bearings 32.
Rotation of the roller body 33 in relation to the tubular piece 31 causes the
permanent magnets 43 to move in relation to the induction coils 42, thus generating an
alternating current in the latter, said current being guided via the line 42a to the electric
consumers provided in the cable car 2 and to accumulators provided on the
supports 11. A track roller 3 is rotated by rolling of the latter along a carrying cable 1,
and a carrying roller 3a is rotated by a traction cable 1a which is guided via the latter
or by a carrying and conveying cable 1b guided via the latter.
The composition of a carrying roller 3 or of a track roller 3a is explained below
with reference to Fig. 4. The first roller body part 33a is embodied with the track
ring 34, the elastic rings 35, the flanged disks 36, the securing rings 37, the pressure
compensating element 45 and with the securing screw 38. The inner surface of the
first roller body part 33a is embodied with steps running all the way around. The
carrying ring 43a together with the permanent magnets 43 is inserted into the roller
body part 33a from the right. The left annular bearing 32 is then pressed in from the
left. Subsequently, the preassembled tubular piece 31 with the carrying ring 44, the
soft iron core 41, the induction coils 42 and the line 42a is inserted into the annular left
bearing 32 from the right. The second roller body part 33b together with the annular
right bearing 32 pressed into the latter is then inserted from the right into the first roller
body part 33a and onto the tubular piece 31. Finally, the sleeve 31b, a sealing
lamella 32a, a spacer ring 32b and a sleeve 31a are inserted from the left, and a
sealing lamella 32a, a spacer ring 32b and a sleeve 31a are inserted from the right.
The second embodiment, illustrated in Fig. 5, of a track roller 3 or carrying
roller 3a according to the invention substantially coincides with the track roller 3 or
carrying roller 3a illustrated in Fig. 3, wherein the functionally identical components are
provided with same reference numbers. Said track roller 3 or carrying roller 3a differs
from the roller 3, 3a according to Fig. 3 in that the roller body 33 is embodied as a
single piece, wherein said roller body is approximately hollow and cylindrical. By this
means, the carrying ring 31, the soft iron core 41 together with the induction coils 42,
the carrying ring 43a embodied with the permanent magnets 43, the two annular
bearings 32, the sealing lamellae 32a, the spacer rings 32b and the sleeves 31a
and 31b can be inserted into said roller body.
This results in the production of a track roller 3 or a carrying roller 3a, the outer
configuration of which corresponds identically to the track rollers or carrying rollers
used in the cableway system, thus enabling it to be useable instead of one of the track
rollers or carrying rollers, wherein it also fulfils the function of an electric generator
without further technical measures being required for this purpose. A track roller or
carrying roller of this type additionally serves to generate current in order to feed
electric apparatuses or accumulators.
[0035] Owing to the fact that the generator 4 is located in the interior of said track
roller 3 or carrying roller 3a, the generator is optimally protected from climatic
influences, in particular from the ingress of water or moisture.
