According to the 3D printer provided by the invention, the small-size motor output is decelerated by the planetary reduction gear and the driving output torque is increased, so that the nozzle assembly of the 3D printer improves movement stability, improves printing precision, and expands the effective print space, and obtains sufficient torque and driving force.
Description
Technical field
The present invention relates to a kind of 3D printer, be specifically related to the drive unit on a kind of 3D printer.
Background technique
In existing 3D printer, drive the motor size of nozzle component wire feeding gear large, Heavy Weight, make on the one hand nozzle component poor stability in moving process, easily produce the phenomenon of shivering and affect printing precision, large-sized motor has occupied larger space on the other hand, has tied up the useful space that 3D prints.In order to improve this phenomenon, a lot of novel 3D printers start to attempt using small volume motor, but this has brought another one problem, is exactly the torsion deficiency of small volume motor, cannot meet nozzle component and drive required.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of 3D printer, turn round hypodynamic problem while using small size motor to solve.
Technological scheme: for solving the problems of the technologies described above, 3D printer provided by the invention, comprises nozzle component, motor, and the wire feeder on described nozzle component is driven by motor by planetary reduction gear;
Described planetary reduction gear comprises driving gear, 3 above driven gear, support, bearing, rack fixing seats, and described driving gear is driven by motor;
The circumferentially uniform driven gear central shaft identical with driven gear quantity of described support one side, another side is axially externally provided with transmission shaft;
Described rack fixing seat is provided with circular cylindrical cavity, is provided with gear ring along cylindrical cavity body sidewall, and in described rack fixing seat, circular cylindrical cavity bottom is provided with delivery outlet;
Described driven gear is socketed on the driven gear central shaft on support, and a part of gear engages with the driving gear that is positioned at carriage center position, and another part gear engages with the gear ring on rack fixing seat;
Driving sleeve on described support is connected on and in bearing, passes described delivery outlet and drive the wire feeder on nozzle component.
As preferably, the quantity of described driven gear and driven gear central shaft is 4 or 5 or 6.
Preferably, described bearing is self oiling bearing, and described support is circular support.
Preferably, the diameter dimension of described driving gear is less than the diameter dimension of driven gear.
Can be as required, the diameter dimension ratio of configuration driving gear, driven gear and rack fixing seat gear ring, thus obtain different reduction speed ratio, and then obtain the driver output of different torsion.
Beneficial effect: 3D printer provided by the invention, wire feeder on its nozzle component is driven by motor by planetary reduction gear, because adopting small volume motor size little lightweight, but torsion deficiency, when the present invention is slowed down to small size motor output by planetary reduction gear, increase the torsion of driver output, make the nozzle component of 3D printer promote the moving stability, improved printing precision, when having expanded effective print space, obtained enough driving forces and torsion.
Brief description of the drawings
Fig. 1 is the erection drawing of 3D printer planetary reduction gear of the present invention;
Fig. 2 is the general assembly structural representation front view of 3D printer planetary reduction gear of the present invention;
Fig. 3 is the general assembly structural representation right elevation of 3D printer planetary reduction gear of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment: this 3D printer comprises nozzle component, motor, wire feeder on described nozzle component is driven by motor by planetary reduction gear, this planetary reduction gear erection drawing as shown in Figure 1, comprise 1,3 driven gears 2 of driving gear, support 3, bearing 4, rack fixing seat 5, described bearing 4 is self oiling bearing.Described driving gear 1 is driven by motor.
The circumferentially driven gear central shaft 6 of uniform 3 of described support 3 one sides, another side is axially externally provided with transmission shaft 7.The present embodiment medium-height trestle 3 is steering wheel shape, can certainly be designed to the conventional shape that circle, Hexagon or other polygonals etc. can at the uniform velocity rotate.
Described rack fixing seat 5 is provided with circular cylindrical cavity, is provided with gear ring 8 along cylindrical cavity body sidewall, and in described rack fixing seat 5, circular cylindrical cavity bottom is provided with delivery outlet 9.Transmission shaft 7 on support 3 is socketed in bearing 4, and the delivery outlet 9 passing on rack fixing seat 5 is externally exported.
The general assembly structural representation front view of this planetary reduction gear as shown in Figure 2, described driven gear 2 is socketed on the driven gear central shaft 6 on support 3, part gear engages with the driving gear 1 that is positioned at support 3 central positions, and another part gear engages with the gear ring 8 on rack fixing seat 5.
The general assembly structural representation right elevation of this planetary reduction gear as shown in Figure 3, the delivery outlet that transmission shaft 7 passes on rack fixing seat 5 is externally exported, in order to drive the wire feeder on nozzle component, as the wire feeding gear on nozzle component or nozzle component change gear etc.
Described in the present embodiment, the diameter dimension of driving gear 1 is less than the diameter dimension of driven gear 2.
Because the diameter of gear ring 8 is greater than the diameter of driving gear 1, thus can realize motor-driven deceleration output, thus obtain larger torsion.Can certainly as required, change the diameter dimension of driving gear, driven gear and rack fixing seat gear ring, thereby obtain different reduction speed ratio and torsion.Described driven gear 2 and the quantity of driven gear central shaft 6 also can be configured to other quantity such as 4 or 5 or 6 as required.
Working procedure of the present invention is: the motor of 3D printer drives driving gear 1 to rotate in support 3 central positions, because 3 driven gears 2 are socketed on 3 driven gear central shafts 6 circumferential uniform on support 3, part gear engages with the driving gear 1 that is positioned at support 3 central positions, another part gear engages with the gear ring 8 on rack fixing seat 5, when so driving gear 1 rotates under motor drives, can drive the gear ring 8 interior rotation of 3 driven gears that engage with its gear on rack fixing seat 5, thereby drive support 3 unitary rotation, and then obtain the axially deceleration large torsion driver output of the upper transmission shafts 7 that arrange of support 3.Transmission shaft 7 is socketed in self oiling bearing 4 and passes delivery outlet 9, in order to drive the gear rotation that nozzle component upper wire feeding hose device is relevant, thereby has obtained the deceleration output of large torsion.In the time that driving gear 1, driven gear 2 are made as different ratio from the diameter of gear ring 9, can obtain corresponding different reduction speed ratio.
Above implementation column does not form restriction to the present invention; especially diameter of driven gear number, driving gear, driven gear and gear ring etc.; relevant staff is not departing from the scope of the technology of the present invention thought, and various variation and the amendment carried out, all drop in protection scope of the present invention.
