Backlash designer with worm gear in the transmission. [Prior Art] [0002] Press, generally the most common in mechanical operation is the use of the transmission mechanism, and the transmission mechanism is the most widely used, and there are many methods used in the technology, such as 曰本特开平7 -1 48632, which is provided with two parallel worms in the machine table, the two worms respectively correspond to the two worm gears, and the two worm gears respectively correspond to the work table above the transmission, however, the above structure is two parallel due to the worm It is set so that it cannot cancel the thrust of each other when it is transmitted, so the axial thrust of the transmission is large. In addition, another embodiment of the technology disclosed in the Japanese case has an inner worm inside the machine, and an outer worm corresponding to the outer worm, and two inner and outer worms corresponding to the two transmissions. a worm wheel, and the two worm gears respectively correspond to the work table above the transmission. However, although the inner and outer worms are coaxial transmissions, the mechanism is complicated because of the combination of the sleeves, and at the same time, the manufacturing cost of the two worms is high, and It is also necessary to manually adjust the exact corresponding assembly to match the worm gear. In addition, the corresponding inner and outer worms cannot be designed with axial displacement control (cannot have the function of adjusting the control backlash), that is, the inner and outer worms The assembly is basically free of backlash, but if it needs to adjust the backlash state, it needs to be directed to the inner and outer worms. 09810688 (^单单除1第4页/共25页1013165371-0 1.374227 101 May On the 01st, the correction of the circumferential phase of the §« page bar can eliminate the backlash state, but the circumferential phase adjustment of the inner and outer worms needs to be disassembled and the tension block can be performed.

The worm is disposed at the rear of the worm with corresponding front and rear wedge blocks, and the rear wedge block is driven by a power element to generate a displacement front slanting wedge block, so that the front wedge block pushes the worm displacement to eliminate the back Gap; thereby, 09810688 (^ single number AD1G1 page 5 / total 25 pages 1013165371-0 1374227 • May 01, 101, according to the replacement page to eliminate the backlash of the transmission mechanism to achieve precise position control The backlash eliminating device of the transmission mechanism further comprises a coupling between the power source and the worm, and a thrust bearing between the worm and the front wedge block, and the thrust worm is used to eliminate the backlash. The coupling absorbs a slight amount of displacement of the worm; and the thrust bearing can withstand the axial thrust, so that the worm and other mechanisms are not injured in the actuating procedure.
