Abstract
An eccentric orbit abrading apparatus includes a housing having a base for supporting the abrading apparatus on a surface. A workpiece support member is mounted on the housing and provides a surface for supporting the workpiece thereon. A motor is mounted in the housing and includes a motor shaft that may selectively rotate about a first rotational axis. A transmission transmits the rotational motion of the motor shaft to a platen so that as the motor shaft rotates, the platen is caused to rotate about a second rotational axis that is offset from and orbits about the first rotational axis.
Claims41
An abrading apparatus comprising:
- a housing comprising a base adapted to support said housing on a surface;
- a workpiece support member mounted on said housing;
- a motor mounted within said housing and comprising a motor shaft, said motor shaft selectively rotatable about a first rotational axis;
- a platen;
- and
- a transmission, said transmission transmitting rotation of said motor shaft to said platen so that as said motor shaft rotates, said platen is urged to rotate about a second rotational axis that is offset from and orbits about said first rotational axis.
An abrading apparatus comprising:
- a base adapted to support the abrading apparatus on a surface;
- a housing connected to said base;
- a workpiece support member mounted on said housing;
- a motor connected to said housing, said motor comprising a motor shaft rotatable about a first axis of rotation;
- a platen rotatable about a second axis of rotation, said second axis of rotation differing from said first axis of rotation, said platen coupled to said motor shaft by a transmission, said transmission orbiting said second axis of rotation in a circular path about said first axis of rotation as said motor shaft rotates.
The abrading apparatus of 23 wherein said platen further comprises a platen support, said platen support defining said bore accepting said spindle.
An abrading apparatus for abrading material from a workpiece, the abrading apparatus comprising:
- a housing;
- a base connected to said housing, said base adapted to support said housing on a surface so that an operator may abrade material from the workpiece without the need to manipulate a position of the abrading apparatus;
- a rotatable platen;
- a workpiece support connected to said housing;
- a motor mounted on said housing, said motor comprising a motor shaft rotatable about a first axis of rotation;
- and
- a transmission connected to said platen and said motor shaft said transmission transmitting rotation of said motor shaft to said platen, said platen rotatable about a second axis of rotation defined by said transmission, said second axis of rotation offset from said first axis of rotation, said second axis of rotation orbiting about said first axis of rotation as said motor shaft rotates.
An abrading apparatus for abrading material from a workpiece, the abrading apparatus comprising:
- a housing;
- means for positioning said housing on a surface;
- a workpiece support connected to said housing;
- a platen rotatable about an axis of rotation;
- a motor connected to and at least substantially enclosed by said housing and comprising a rotatable motor shaft;
- and
- a transmission linking said motor shaft and said platen, said transmission urging said axis of rotation of said platen to orbit about a point as said motor shaft rotates.
