The present invention is arranged further: described lock screw forms spiral through the axial hole on fixed gear with the axial threaded hole on adjustable gear and is connected.
Adopt above-mentioned further setting, by arranging lock screw, form spiral with adjustable gear to be connected, thus after adjustment backlash, adjustable gear and fixed gear are forced together tightly, the surface of contact of these two gears forms friction torque, two gears are rotated together, adopt above-mentioned further setting, the number of lock screw can be multiple, in the present invention preferably three, three lock screws are evenly distributed on the end face of fixed gear (or adjustable gear) together with an adjustment screw rod B (or adjustment screw rod A), be conducive to easy to process on the one hand, ensure that adjustable gear and fixed gear surface of contact have enough friction torque on the other hand, and larger gear transmission load can be born.
The present invention is arranged further again: described fixed gear, annulus boss and coaxial thereto are arranged.
Adopt and above-mentionedly to arrange further again, it is simple that structure is set like this, easily manufactured, be conducive to the installation of adjustable gear and twin-screw regulating device.
The present invention is arranged further again: described push rod and the axial hole of fixed gear have adjustment space.
Adopt and above-mentionedly to arrange further again, object is that the push rod rotated with adjustable gear has and necessarily adjusts space, and this space does not need very large, and the backlash of general adjustment only has several.
The present invention is arranged further again: the axial hole of described lock screw and fixed gear has adjustment space.
Adopt and above-mentionedly to arrange further again, object is that the lock screw rotated with adjustable gear has and necessarily adjusts space, and this space does not need very large, and the backlash of general adjustment only has several.
The present invention is arranged further again: the both ends of the surface structure of described adjustment screw rod A and adjustment screw rod B is tack, an end face and push rod inconsistent, other end is provided with straight groove or cross recess.
