Abstract
A drive assembly comprises a motor with a pulley coupled to its rotary output shaft. A pulley support structure is fixed with respect to the motor and is coupled to the pulley by bearings configured to allow rotation of the pulley with respect to the support structure. The drive assembly is incorporated into a belt drive system. Lateral forces exerted on the pulley by the drive belt are transmitted to the pulley support structure via the bearings rather than being exerted on the rotary output shaft.
Claims20
A drive assembly comprising:
- a motor having a rotary output shaft that is rotatable about a rotation axis;
- a pulley coupled to the rotary output shaft for rotation with the rotary output shaft about said rotation axis;
- and
- a pulley support structure,
- wherein the support structure is fixed with respect to said motor and is coupled to said pulley by at least one bearing that is configured to allow rotational movement of said pulley with respect to said support structure about said rotation axis.
A drive system comprising a drive assembly, the drive assembly comprising:
- a motor having a rotary output shaft that is rotatable about a rotation axis;
- a pulley coupled to the rotary output shaft for rotation with the rotary output shaft about said rotation axis;
- and
- a pulley support structure,
- wherein the support structure is fixed with respect to said motor and is coupled to said pulley by at least one bearing that is configured to allow rotational movement of said pulley with respect to said support structure about said rotation axis,
- wherein said pulley is a drive pulley of said drive system and is coupled to a driven pulley of said drive system by at least one drive loop, preferably at least one drive belt, in order to drive said driven pulley.
A vibratory apparatus comprising a vibratory drive system, wherein the vibratory drive system comprises a drive system, the drive system comprising a drive assembly, the drive assembly comprising:
- a motor having a rotary output shaft that is rotatable about a rotation axis;
- a pulley coupled to the rotary output shaft for rotation with the rotary output shaft about said rotation axis;
- and
- a pulley support structure,
- wherein the support structure is fixed with respect to said motor and is coupled to said pulley by at least one bearing that is configured to allow rotational movement of said pulley with respect to said support structure about said rotation axis,
- wherein said pulley is a drive pulley of said drive system and is coupled to a driven pulley of said drive system by at least one drive loop, preferably at least one drive belt, in order to drive said driven pulley.
