Abstract

A flange arrangement includes a power shaft, a flanged hub connected detachably to the power shaft, and a stop member configured to detachably hold the flanged hub on the power shaft and to exert a disassembly force on the flanged hub so as to be able to rotate about a rotation axis of the power shaft.

First claim

What is claimed is:

1. A flange arrangement, comprising:
a power shaft;
a flanged hub connected detachably to the power shaft, wherein the flanged hub has an involute spline in mesh with an involute spline on the power shaft; and
a stop member configured to hold the flanged hub on the power shaft, wherein the stop member can be rotated about a rotation axis of the power shaft such that in a disassembly position of the stop member, a support segment of the flanged hub opposes a support segment of the stop member to be able to exert a disassembly force on the flanged hub by means of the stop member, wherein at least one of: the support segment of the stop member extends radially outward and the support segment of the flanged hub extends radially inward.

2. The flange arrangement of claim 1 , wherein the disassembly force exerted by the stop member is aligned along the rotation axis of the power shaft.

3. The flange arrangement of claim 1 , wherein the stop member has a first front face in facing relation to the power shaft so as to exert a holding force on the flanged hub, and a second front face which faces away from the power shaft and exerts the disassembly force.

4. The flange arrangement of claim 3 , wherein the stop member is configured for rotation between a holding position, in which the stop member exerts the holding force, and a disassembly position in which the stop member exerts the disassembly force.

5. The flange arrangement of claim 1 , further comprising a fastener received in the stop member to exert the disassembly force onto the flanged hub.

6. The flange arrangement of claim 1 , wherein the power shaft is embodied as a solid shaft or as a hollow shaft.

7. The flange arrangement of claim 1 , wherein the flanged hub comprises:
a cylinder section having the involute spline;
a flange section adjoining the cylinder section; and
a support collar configured to axially support the flanged hub on the power shaft as the involute spline of the cylinder section meshes the involute spline of the power shaft.

8. The flange arrangement of claim 1 , wherein the-stop, member comprises:
an annular body having a plurality of cut-outs; and
fasteners received in the cut-outs and interacting with the power shaft.

9. A gear unit, comprising a flange arrangement, said flange arrangement comprising a power shaft embodied as a drive shaft or as an output shaft, a flanged hub connected detachably to the power shaft and comprising a cylinder section having an involute spline, a flange section adjoining the cylinder section, and a support collar configured to axially support the flanged hub on the power shaft as the involute spline of the cylinder section meshes an involute spline of the power shaft, and a stop member configured to hold the flanged hub on the power shaft wherein the stop member can be rotated about a rotation axis of the power shaft such that in a disassembly position of the stop member a support segment of the flanged hub opposes a support segment of the stop member to be able to exert a disassembly force on the flanged hub by means of the stop member, wherein at least one of: the support segment of the stop member extends radially outward and the support segment of the flanged hub extends radially inward.

10. An electric motor, comprising:
a power shaft, the power shaft of the electric motor embodied as an output shaft; and
a flange arrangement, said flange arrangement comprising the power shaft, a flanged hub connected detachably to the power shaft, wherein the flanged hub has an involute spline in mesh with an involute spline on the power shaft, and a stop member configured to hold the flanged hub on the power shaft, wherein the stop member can be rotated about a rotation axis of the power shaft such that in a disassembly position of the stop member a support segment of the flanged hub opposes a support segment of the stop member to be able to exert a disassembly force on the flanged hub by means of the stop member, wherein at least one of: the support segment of the stop member extends radially outward and the support segment of the flanged hub extends radially inward.

11. The electric motor of claim 10 , wherein the flanged hub and the power shaft are connected via a taper seat, a cylindrical press fit, or a shaft-hub connection with key connection.

12. A drive train for a wind turbine, said drive train comprising:
a generator;
a gear unit connected as a first connection in a torque-transmitting manner to the generator; and
a power shaft connected as a second connection in a torque-transmitting manner to the gear unit;
wherein at least one of the first connection and the second connection is formed as a flange arrangement that includes: a flanged hub connected detachably to the power shaft, and a stop member configured to hold the flanged hub on the power shaft wherein the stop member can be rotated about a rotation axis of the power shaft such that, in disassembly position of the stop member, a support segment of the flanged hub opposes a support segment of the stop member to be able to exert a disassembly force on the flanged hub by means of the stop member, wherein at least one of: the support segment of the stop member extends radially outward and the support segment of the flanged hub extends radially inward.

13. A wind turbine, comprising:
a nacelle;
a rotor attached to the nacelle; and
a drive train received in the nacelle and comprising a generator, a gear unit connected as a first connection in a torque-transmitting manner to a generator, a power shaft connected as a second connection in a torque-transmitting manner to the gear unit, wherein at least one of the first connection and the second connection is formed as a flange arrangement that includes: a flanged hub, connected detachably to the power shaft, and stop, member configured to hold the flanged hub on the power shaft wherein the stop member can be rotated about a rotation axis of the power shaft such that in a disassembly position of the stop member, a support segment of the flanged hub opposes a support segment of the stop member to be able to exert a disassembly force on the flanged hub the means of the stop member, wherein at least one of: the support segment of the stop member extends radially outward and the support segment of the flanged hub extends radially inward.

14. An industrial application, comprising:
a drive unit;
a gear unit;
an output unit connected to the gear unit in a torque-transmitting manner; and
a connection provided between the gear unit and at least one of the drive unit and the output unit, the connection including a flange arrangement, wherein the flange arrangement comprises a power shaft, a flanged hub connected detachably to the power shaft, and a stop member configured to hold the flanged hub on the power shaft, wherein the stop member can be rotated about a rotation axis of the power shaft such that in a disassembly position of the stop member, a support segment of the flanged hub opposes a support segment of the stop member to be able to exert a disassembly force on the flanged hub by means of the stop member, wherein at least one of: the support segment of the stop member extends radially outward and the support segment of the flanged hub extends radially inward.
