Abstract
An actuator comprising: a motor having a housing and a drive shaft, the motor arranged to rotate the drive shaft relative to the housing about a drive shaft axis; a first torque transfer device arranged to transfer torque from the drive shaft to a second shaft, the second shaft being rotatable about a second shaft axis parallel to and radially spaced from the drive shaft axis; and an output torque transfer device arranged to transfer torque from the second shaft to the housing of the motor; wherein, upon rotation of the drive shaft relative to the motor housing, the housing of the motor is arranged to rotate relative to the position of the second shaft axis.
Claims24
An actuator comprising:
- a motor having a motor housing and a drive shaft, the motor arranged to rotate the drive shaft relative to the motor housing about a drive shaft axis;
- a first torque transfer device arranged to transfer torque from the drive shaft to a second shaft, the second shaft being rotatable about a second shaft axis parallel to and radially spaced from the drive shaft axis;
- and
- an output torque transfer device arranged to transfer torque from the second shaft to the motor housing,
- wherein:
- when the motor housing is maintained in a fixed position, rotation of the drive shaft relative to the motor housing causes rotation of the position of the second shaft axis about the motor housing, or
- when the position of the second shaft axis is maintained in a fixed position, rotation of the drive shaft relative to the motor housing causes rotation of the motor housing about the position of the second shaft axis.
An actuator comprising:
- a motor having a housing and a drive shaft, the motor arranged to rotate the drive shaft relative to the housing about a drive shaft axis;
- a first torque transfer device arranged to transfer torque from the drive shaft to a second shaft, the second shaft being rotatable about a second shaft axis spaced from the drive shaft axis;
- and
- an output torque transfer device arranged to transfer torque from the second shaft to an output member, the output member being arranged to rotate about an output axis;
- wherein the output axis is coaxial with the drive shaft axis, and
- wherein the output member is fixedly attached relative to the stator of the motor.
An actuator comprising:
- a motor having a housing and a drive shaft, the motor arranged to rotate the drive shaft relative to the housing about a drive shaft axis;
- a first torque transfer device arranged to transfer torque from the drive shaft to a second shaft, the second shaft being rotatable about a second shaft axis spaced from the drive shaft axis;
- and
- an output torque transfer device arranged to transfer torque from the second shaft to an output member, the output member being arranged to rotate about an output axis;
- wherein the motor is arranged at least partially within the output member, and
- wherein:
- (i) the output member is substantially annular,
- (ii) the output member is a pulley, or
- (iii) the stator of the motor is fixedly attached with respect to the output member.
An actuator comprising:
- a motor having a housing, a stator, a rotor, and a drive shaft, the motor arranged to rotate the drive shaft relative to the housing about a drive shaft axis;
- a first torque transfer device arranged to transfer torque from the drive shaft to a second shaft, the second shaft being rotatable about a second shaft axis spaced from the drive shaft axis;
- and
- an output torque transfer device arranged to transfer torque from the second shaft to an output member, the output member being arranged to rotate about an output axis;
- wherein the output member is fixedly attached relative to the stator of the motor.
