Abstract

The present invention discloses a 3D printer, which comprises a spraying nozzle assembly, a motor and a bearing assembly, wherein the bearing assembly comprises a driving gear, a driven gear, an outer bearing, a rolling body and an inner, the inner bearing is provided with a first cylindrical cavity, one side is provided with a transmission shaft, the side wall of the first cylindrical cavity is provided with a tooth ring, a driven gear center shaft corresponding to the driven gear is arranged inside the first cylindrical cavity, the outer bearing is provided with a second cylindrical cavity, the bottom portion of the cylindrical cavity is provided with an output hole, the rolling body is positioned between the outer wall of the inner bearing and the side wall of the second cylindrical cavity, and the transmission shaft is sleeved inside the bearing, and penetrates through the output hole, and drives the wire feeder on the spraying nozzle assembly. According to the present invention, the speed reducing is performed on the small size level reduction output through the bearing assembly while the drive output torque force is increased, such that the specific-progression transmission ratio is achieved, the stability of the 3D printer spraying nozzle assembly is improved, the printing precision is improved, and the use is easy.

Description

technical field [0001] The invention relates to a 3D printer, in particular to a driving device on the 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive material to create three-dimensional objects. At this stage 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. 3D printing has brought about a global manufacturing revolution. In the past, component design was completely dependent on whether the production process could be realized. The emergence of 3D printers will subve...
