Abstract
A fan structure is provided with a fan, a fan support, a base, and a motor. The fan is provided with a rotational shaft rotatable about a rotational shaft, and a blade coupled to the rotational shaft to rotate about the rotational axis together with the rotational shaft. The fan support rotatably supports the rotational shaft. The base slidably supports the fan support so as to be slidable in the sliding direction. The motor includes a motor main body supported by a fan support opposite to the rotational shaft of the fan in the axial direction along the rotational axis, and a motor rotational shaft connected to the rotational shaft so as to rotate the rotational shaft.
Claims20
A fan structure comprising:
- a fan comprising:
- a rotational shaft rotatable about a rotational axis;
- and
- a blade coupled to the rotational shaft to rotate about the rotational axis together with the rotational shaft;
- a fan support rotatably supporting the rotational shaft;
- a base slidably supporting the fan support in a sliding direction;
- and
- a motor comprising:
- a motor main body supported by the fan support opposite to the rotational shaft of the fan in an axial direction along the rotational axis;
- and
- a motor rotational shaft connected to the rotational shaft so as to rotate the rotational shaft,
- wherein the fan support comprises:
- a base plate having a first opening;
- a support plate supporting the motor main body;
- and
- a plurality of beams each connecting the support plate and the base plate,
- wherein the base comprises:
- an attachment configured to be attached to an exterior frame forming an engine compartment of a work vehicle;
- and
- a top plate having a second opening larger than the first opening and connected to the attachment, and
- wherein the fan is supported by the support plate such that the fan passes through the first opening and the second opening.
