Complicated and maintenance is difficult, and use cost is higher.
Therefore how above-mentioned existing problem and disappearance will be solved, the class of the desired most ardently research and development of as related dealer
Topic is located.
The content of the invention
The main object of the present invention is in that, using screw thread conversion speed, and then simplifies reducing gear, convenient
Maintenance and reduction use cost.
It is that, up to above-mentioned purpose, the speed reduction gearing of the present invention is provided with pedestal and transmission group, transmission group tool
There are the first power transmission shaft, second driving shaft and displacement plate, the first power transmission shaft surface is provided with the first external screw thread,
Second driving shaft surface is provided with the second external screw thread, and the second externally threaded helical pitch is more than the first externally threaded helical pitch,
And the first power transmission shaft is articulated in pedestal, and the first power transmission shaft and second driving shaft respectively with two end of second driving shaft
In parallel shape, the first internal thread and the second internal thread in displacement plate, are provided with, the first internal thread system is screwed together in
First external screw thread of the first power transmission shaft, the second internal thread are then screwed together in the second external screw thread of second driving shaft.
The pedestal is provided with two pieces of substrates, is provided with plural number guide rod between two pieces of substrates, and guide rod is parallel to the
A plurality of perforation are provided with one power transmission shaft and second driving shaft, and the displacement plate, in perforation, bushing is provided with,
Bushing is socketed on guide rod outer peripheral edge.
The pedestal is provided with two pieces of substrates, is provided with bearing, and two end of the first power transmission shaft is provided with substrate
One articulated section, two end of second driving shaft are provided with the second articulated section, and axle is received with the second articulated section in the first articulated section
Support is positioned at substrate.
By said structure, when the first drive axis, the first external screw thread of the first power transmission shaft is to promote
First internal thread of displacement plate, makes displacement plate lateral displacement, and while displacement plate is moved, displacement plate
Second internal thread is the second external screw thread that can promote second driving shaft, rotates second driving shaft, and because of second
Externally threaded helical pitch is more than the first externally threaded helical pitch, makes the slewing rate of second driving shaft less than the first transmission
The slewing rate of axle.

Specific embodiment
Refer to shown in Fig. 1, can be seen that by figure, the present invention is provided with pedestal 1 and transmission group 2,
Wherein：
The pedestal 1 with two pieces of substrates 11, plural number guide rod 12, and be arranged at the bearing 13 of substrate 11,
Plural number guide rod 12 is in parallel shape, and 12 2 side of guide rod is connected to two pieces of substrates 11.
The transmission group 2 has the first power transmission shaft 21, second driving shaft 22 and displacement plate 23, the first transmission
21 surface of axle is provided with the first external screw thread 211, and 22 surface of second driving shaft is provided with the second external screw thread 221,
Helical pitch of the helical pitch of the second external screw thread 221 more than the first external screw thread 211, and 21 2 end of the first power transmission shaft is arranged
There is the first articulated section 212,22 2 end of second driving shaft is provided with the second articulated section 222, the first articulated section 212
It is substrate 11 that pedestal 1 is positioned at by 13 support of bearing with the second articulated section 222, and the first power transmission shaft 21
With second driving shaft 22 be parallel to guide rod 12, and be provided with displacement plate 23 first internal thread 231, the
Two internal threads 232 and a plurality of perforation 233, the first internal thread 231 is to be screwed together in the first power transmission shaft 21
First external screw thread 211, the second internal thread 232 are then screwed together in the second external screw thread 221 of second driving shaft 22,
And bushing 234 is provided with perforation 233, bushing 234 is to be socketed on 12 outer peripheral edge of guide rod.
Refer to shown in Fig. 2, by figure it can be seen that, the first power transmission shaft 21 and second driving shaft 22 according to
Pivot with bearing 13, and guide rod 12 helps the 234 internal diameter lateral displacement of bushing for displacement plate 23 being made according to perforation 233,
Therefore the first power transmission shaft 21 is when rotating, the first external screw thread 211 of the first power transmission shaft 21 is to promote displacement plate
23 the first internal thread 231, makes the lateral displacement on the guide rod 12 of displacement plate 23, and moves in displacement plate 23
While, the second internal thread 232 of displacement plate 23 is the second external screw thread 221 that can promote second driving shaft 22,
So that second driving shaft 22 agrees to bearing 13 to pivot, it is more than outside first by the helical pitch of the second external screw thread 221
The helical pitch of screw thread 211, makes the slewing rate of second driving shaft 22 less than the slewing rate of the first power transmission shaft 21,
To reach the purpose of deceleration.
Therefore the present invention is can to solve existing problem with disappearance, its key technology is that present invention system is sharp
With first internal thread 231 and the second internal thread 232 of displacement plate 23, the first power transmission shaft of different lead is screwed togather
21 the first external screw thread 211, and the second external screw thread 221 of second driving shaft 22, make the first power transmission shaft 21
When rotating and drive second driving shaft 22 to rotate, different slewing rates are produced, to reach the purpose of deceleration,
And reducing gear, convenient maintenance and reduction use cost can be simplified.
