Abstract
An apparatus for imparting complex rotary motion is used to lap an inner spherical diameter surface of a workpiece. A lapping tool consists of a dome and rod mounted along the dome's vertical axis. The workpiece containing the lapping tool is held in a gimbal which uses power derived from a secondary takeoff means to impart rotary motion about a horizontal axis. The gimbal is rotated about a vertical axis by a take means while mounted at a radially outward position on a rotating arm.
Claims12
An apparatus for imparting complex rotatary motion to at least one subject comprising:
- at least one holding means for said subject which rotates said subject around a horizontal axis;
- at least one means for rotating said holding means around a vertical axis;
- at least one rotating arm to which said rotating means is attached at a radially outward position, said rotating arm rotating about a vertical axis counter to the rotary motion of said rotating means;
- a power means to rotate said rotating arm;
- at least one takeoff means to derive power from power means and induce rotary motion to said rotating means;
- and
- at least one secondary takeoff means to derive power from takeoff means and transmit power to said holding means for inducing rotary motion to said subject.
A spherical inner diameter lapping apparatus comprising:
- at least one lapping tool consisting of a grinding surface dome and a rod attached along the vertical axis of the dome, said lapping tool fitting within at least one workpiece;
- at least one shell for enclosing said workpiece;
- at least one holding means for said shell which rotates said shell around a horizontal axis;
- at least one means for rotating said holding means around a vertical axis;
- at least one rotating arm to which said rotating means is attached at a radially outward position, said rotating arm rotating about a vertical axis counter to the rotary motion of said rotating means;
- a power means to rotate said rotating arm;
- at least one takeoff means to derive power from power means and induce rotary motion to said rotating means;
- and
- at least one secondary takeoff means to derive power from takeoff means and transmit power to said holding means for inducing rotary motion to said shell.
