A rotary table device comprising:
- a housing having a space portion formed therein;
- a main shaft installed in the space portion and provided with a worm wheel coupled along an outer circumference thereof;
- a pair of worm shafts provided to be engaged with the worm wheel at both sides of the worm wheel in a predetermined position of the space portion;
- a driving motor installed on one side of the housing;
- a power transmission member installed on an upper surface of the housing to transmit a driving force of the driving motor to the pair of worm shafts;
- and
- a clearance adjustment member installed in a predetermined position of each lower end of both sides of the housing, wherein the power transmission member comprises:
- a pair of belt pulleys provided on the upper surface of the housing and coupled to each end portion of the pair of worm shafts;
- a pair of idle gears provided in a predetermined position of the upper surface of the housing so as to be positioned between the pair of belt pulleys;
- and
- a belt connecting the pair of belt pulleys and the pair of idle gears to a driving shaft of the driving motor.
A rotary table device comprising:
- a housing having a space portion formed therein;
- a main shaft installed in the space portion and provided with a worm wheel coupled along an outer circumference thereof;
- a pair of worm shafts provided to be engaged with the worm wheel at both sides of the worm wheel in a predetermined position of the space portion;
- a driving motor installed on one side of the housing;
- a power transmission member installed on an upper surface of the housing to transmit a driving force of the driving motor to the pair of worm shafts;
- and
- a clearance adjustment member installed in a predetermined position of each lower end of both sides of the housing, wherein the clearance adjustment member comprises:
- a pair of coupling portions symmetrically coupled to predetermined positions of the both sides of the housing;
- and
- adjustment portions screw-engaged to penetrate centers of the coupling portions, wherein the adjustment portions adjust a gap between the worm wheel and the worm shaft through pressing of outer sides of the pair of worm shafts.
