When transmission long axis rotates under extraneous input torque effect, drive by the first Small taper gear mounted thereto the steep-taper pinion rotation be arranged on jack shaft, thus moment of torsion is passed to jack shaft, drive jack shaft to rotate, in jack shaft rotary course, the second Small taper gear be arranged on transmission minor axis by the steep-taper gear driven be mounted thereon is rotated, thus moment of torsion is passed to transmission minor axis, owing to driving jack shaft by transmission long axis, transmission minor axis is driven by jack shaft, transmission long axis simultaneously engages transmitting torque by Small taper gear with jack shaft steep-taper gear with transmission minor axis, thus make transmission long axis and transmission minor axis output power in the same way, and export equidirectional moment of torsion to conical screw, like this, be adapted as in the process of co-rotating conical twin-screw extruder by incorgruous conical double screw extruder, extruder miscellaneous part for distribution gear case input end and output terminal need not be changed, only need to change distribution gear case, therefore, in retrofit process, change little and expense is low.
Described first Small taper gear, second Small taper gear and steep-taper gear are the taper gears that a kind of reference cone angle is very little, taper gear transmission is a kind of approximate circle Column gear transmission conjugating continuously along axis and become transverse tooth thickness, its addendum modification and transverse tooth thickness are nonlinear along the change of Gear axis, designed by having three pyramidal faces, steep-taper gear and the first Small taper gear, second Small taper gear is meshed, gear teeth backlash is identical, due to the first Small taper gear top circle, gap is left between second Small taper gear top circle, do not participate in engagement, like this, transmission efficiency is high, noise is little.
In further preferably mode of execution, described transmission long axis output terminal is connected with the first sliding cross coupling; Transmission minor axis output terminal is connected with the second sliding cross coupling.
Due to sliding cross coupling, there is simple, the high moment of torsion of structure, high rigidity, high sensitivity and allow the advantage of larger radial and axial deviation, transmission long axis is connected with screw rod by sliding cross coupling with the output terminal of transmission minor axis, larger transmission torsion can be absorbed, long service life and performance safety is reliable.
In further preferably mode of execution, described first Small taper gear two ends are supported by the first selfaligning roller bearing and the second selfaligning roller bearing; Described transmission long axis is provided with the first self-aligning thrust roller bearing; Described second Small taper gear two ends are supported by the 3rd selfaligning roller bearing and the 4th selfaligning roller bearing; Described transmission minor axis is provided with the second self-aligning thrust roller bearing; Described steep-taper gear two ends are supported by the first tapered roller bearing and the second tapered roller bearing.
Due to, tapered roller bearing is particularly suitable for bearing compound (radial and axial) load, and bearing capacity is comparatively large, therefore, by tapered roller bearing supporting steep-taper gear, is conducive to the stability ensureing steep-taper gear transmission moment of torsion; And support the first Small taper gear and the second Small taper gear by selfaligning roller bearing, the effect of aligning can be played, allow to there is radial deflection, be conducive to gear-driven stability.
