Flange arrangement, flanged hub, stop member, gear unit, electric motor, wind turbine and industrial application

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.

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.

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.

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.
