Abstract
Abstract The invention relates to a transmission arrangement in which the transmission includes a friction-cone member which can be arranged with its hub on the motor shaft of a motor, whereby the end of the hub directed towards the motor includes at least one slot, and at this end of the hub there is arranged a clamping collar for clamping the hub to the motor shaft. An anti-friction bearing, arranged on the hub at the portion thereof which is closest to the friction-cone, adapted to resist radial and axial loads, and supported by a housing-flange of the motor, is radially and axially rigidly journalled in the housing-flange.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
A transmission arrangement, comprising: a motor having a housing-flange and a motor shaft; an infinitely variable friction-cone transmission having a friction-cone member including a hollow hub mounted on said motor shaft; an anti-friction bearing adapted to resist rigidly any radially and axially directed loads and in operative contact with said hub and said housing-flange at that end of said hub remote from said motor; and means for connecting to said motor shaft in an articulated manner to that end of said hub which is closest to said motor in such a way so as to avoid triple mounting the motor shaft journally and to accommodate and equalize pitching momentum including tilting or tipping forces acting on said friction-cone member, making said hub quasi-pivotal on said motor shaft and also making possible transmittal of any axial and radial forces encountered during operation of said infinitely variable friction-cone transmission into said housing flange thereby to relieve and unburden said motor shaft.
Claim 2
Dependent Claim
159 words
A transmission arrangement, comprising: a motor having a housing-flange and a motor shaft; an infinitely variable friction-cone transmission having a friction-cone member including a hollow hub mounted on said motor shaft; an anti-friction bearing adapted to resist rigidly any radially and axially directed loads and in operative contact with said hub and said housing-flange at that end of said hub remote from said motor; and means for connecting to said motor shaft in an articulated manner to that end of said hub which is closest to said motor in such a way so as to avoid triple mounting the motor shaft journally and to accommodate and equalize pitching momentum including tilting or tipping forces acting on said friction-cone member, making said hub quasi-pivotal on said motor shaft and also making possible transmittal of any axial and radial forces encountered during operation of said infinitely variable friction-cone transmission into said housing flange thereby to relieve and unburden said motor shaft.
Claim 3
Dependent Claim
47 words
A transmission arrangement according to claim 1, wherein said means for connecting includes at least one projection on said hub at said end closest to said motor to provide a support zone dimensioned in conformity with the diameter of said motor shaft and in operative contact therewith.
Claim 4
Dependent Claim
25 words
A transmission arrangement according to claim 2, wherein said at least one projection is rounded at said support zone as viewed in longitudinal cross section.
Claim 5
Dependent Claim
31 words
A transmission arrangement according to claim 1, wherein said means for connecting includes a sleeve operatively connectible to said motor shaft at said end of said hub closest to said motor.
Claim 6
Dependent Claim
39 words
A transmission arrangement according to claim 4, wherein said sleeve includes a plurality of external gear teeth, and said hub includes a plurality of internal gear teeth that operatively engage said plurality of external gear teeth of said sleeve.
Claim 7
Dependent Claim
25 words
A transmission arrangement according to claim 5, wherein said plurality of external gear teeth of said sleeve are rounded as viewed in longitudinal cross section.
Claim 8
Dependent Claim
48 words
A transmission arrangement according to claim 1, wherein that end of said hub closest to said motor includes at least one slot, and said means for connecting includes a clamping collar operatively arranged on a slotted end of said hub for securing said hub to said motor shaft.
Claim 9
Dependent Claim
20 words
A transmission arrangement according to claim 7, wherein said clamping collar is arranged engageable in the vicinity of said hub.
Claim 10
Dependent Claim
15 words
A transmission arrangement according to claim 7, wherein said hub includes three radially extending slots.
