Precise double-shaft transmission mechanism

A precise double-shaft transmission mechanism mainly solves the problems that an existing positioning transmission mechanism is complex in structure, low in transmission efficiency, not sufficient in output rigidity, weak in bearing capacity and impact-resistant capacity, short in service life and high in production cost. The precise double-shaft transmission mechanism is characterized in that a first horizontal transmission mechanism (101) comprises a horizontal worm gear (4) and a horizontal worm (5) which are engaged with each other; a horizontal motor (1) is connected with the horizontal worm (5) through a horizontal coupler (3); and the horizontal worm gear (4) is used for driving a second horizontal transmission mechanism (105) to move. The precise double-shaft transmission mechanism has the beneficial effects of being compact in structure, small in size, small in weight, low in cost, large in transmission ratio, high in transmission efficiency, large in output rigidity, low in return difference, high i
