Anti backlash adjustment mechanism for gears

A gear box, comprising:

• a gear box housing;
• a driving shaft having a driving shaft gear, wherein the driving shaft is rotatably mounted in the gear box;
• a driven shaft having a driven shaft gear, wherein the driven shaft is rotatably mounted in the gear box so that the driven shaft gear is in operable position with the driving shaft gear;
• an eccentric bearing adjust positioned so as to surround at least a portion of the driven shaft;
• a first tip set screw positioned in the gear box housing in operable position juxtaposed next to the eccentric bearing adjust;
• a second tip set screw positioned in the gear box housing in operable position juxtaposed next to the eccentric bearing adjust;
• and
• wherein the first tip set screw and the second tip set screw are configured to calibrate a center position of the driven shaft by rotating the eccentric bearing adjust to mitigate backlash between the driving shaft gear and the driven shaft gear, wherein the eccentric bearing adjust has a circular cavity for receiving the at least the portion of the driven shaft and the circular cavity of the eccentric bearing adjust has an original center point that moves to an adjusted center point by tightening and loosening the first tip set screw and the second tip set screw.

A gear box, comprising:

• a gear box housing;
• a driving shaft having a driving shaft gear, wherein the driving shaft is rotatably mounted in the gear box;
• a first driven shaft having a first driven shaft upper gear and a second driven shaft lower gear, wherein the first driven shaft is rotatably mounted in the gear box so that the first driven shaft upper gear is in operable position with the driving shaft gear;
• a second driven shaft having a second driven shaft gear, wherein the second driven shaft is rotatably mounted in the gear box so that the second driven shaft gear is in operable position with the first driven shaft lower gear;
• a first eccentric bearing adjust positioned so as to surround at least a portion of the driving shaft;
• a first tip set screw positioned in the gear box housing in operable position juxtaposed next to the first eccentric bearing adjust;
• a second tip set screw positioned in the gear box housing in operable position juxtaposed next to the first eccentric bearing adjust;
• wherein the first tip set screw and the second tip set screw are configured to calibrate a center position of the driving shaft by rotating the first eccentric bearing to mitigate backlash between the driving shaft gear and the first driven shaft gear;
• a second eccentric bearing adjust positioned so as to surround at least a portion of the second driven shaft;
• a third tip set screw positioned in the gear box housing in operable position juxtaposed next to the second eccentric bearing adjust;
• a fourth tip set screw positioned in the gear box housing in operable position juxtaposed next to the second eccentric bearing adjust;
• and
• wherein the third tip set screw and the fourth tip set screw are configured to calibrate a center position of the second driven shaft by rotating the second eccentric bearing to mitigate backlash between the first driven shaft lower gear and the second driven shaft gear, wherein the first eccentric bearing adjust has a circular cavity and the second eccentric bearing adjust has a circular cavity for receiving at least the portion of the driving shaft and at least the portion of the second driven shaft respectively and the circular cavity of the first eccentric bearing adjust has an original center point that moves to an adjusted center point by tightening and loosening the first tip set screw and the second tip set screw.
