Description
Technical Field
The invention relates to a gear surface coating device, in particular to a gear surface coating device for an RV reducer, and belongs to the field of gear machining.
Background
The RV reducer consists of a front stage of a planetary gear reducer and a rear stage of a cycloidal pin gear reducer, has compact structure and large transmission ratio, has a self-locking function under a certain condition, is one of the most common reducers, and has small vibration, low noise and low energy consumption. The RV transmission is a newly-emerging transmission, is developed on the basis of the traditional needle pendulum planetary transmission, not only overcomes the defects of the common needle pendulum transmission, but also has a series of advantages of small volume, light weight, large transmission ratio range, long service life, stable precision, high efficiency, stable transmission and the like. Increasingly receiving wide attention at home and abroad. The RV reducer is composed of a cycloidal pin wheel and a planet support, and has the advantages of small size, strong impact resistance, large torque, high positioning precision, small vibration, large reduction ratio and the like, and is widely applied to the fields of industrial robots, machine tools, medical detection equipment, satellite receiving systems and the like. Compared with the common harmonic transmission in the robot, the variable-speed reducer has much higher fatigue strength, rigidity and service life, has stable return difference precision, and does not obviously reduce the motion precision along with the increase of the service time like the harmonic transmission, so the RV reducer is mostly adopted in the high-precision robot transmission in many countries in the world, and therefore, the RV reducer has the development trend of gradually replacing the harmonic reducer in the advanced robot transmission.
The vacuum magnetron sputtering technology is that an electron trap is formed by utilizing a magnetic field matched with the surface of a cathode, so that electrons are enabled to closely attached to the surface of the cathode to drift under the action of E multiplied by B. The magnetic field orthogonal to the target surface electric field is set, fast electrons generated during sputtering make approximate cycloid motion in the orthogonal electromagnetic field, the electron stroke is increased, the ionization rate of gas is improved, meanwhile, high-energy particles lose energy after colliding with the gas, the temperature of the matrix is lower, and coating can be completed on a non-temperature-resistant material. The technology is the most advanced technology in the glass film technology, is the civilization of the top technology combining three aspects of the aerospace industry, the weapon industry and the nuclear industry, and mainly achieves the effects of energy conservation, environmental protection and the like through the technology for civilian use.
The principle of sputtering coating is that the plasma generated by the abnormal glow discharge of the thin gas bombards the surface of the cathode target under the action of an electric field, molecules, atoms, ions, electrons and the like on the surface of the target are sputtered out, and the sputtered particles have certain kinetic energy and are ejected to the surface of a base body along a certain direction to form a coating on the surface of the base body.
The sputtering coating initially appears as simple direct current diode sputtering, which has the advantages of simple device but low direct current diode sputtering deposition rate; to maintain self-sustaining discharge, it cannot be done at low pressure <0.1 Pa; the application is limited by the defects of being incapable of sputtering insulating materials and the like. A hot cathode and an auxiliary anode are added in the DC dipolar sputtering device to form DC tripolar sputtering. The increased generation of hot electrons by the hot cathode and the auxiliary anode enhances the ionization of the atoms of the sputtering gas, thus enabling sputtering to be performed even at low pressure; in addition, the sputtering voltage can be reduced, so that the sputtering is carried out under the state of low pressure and low voltage; meanwhile, the discharge current is increased and can be independently controlled without being influenced by voltage. An electrode grid is added in front of the hot cathode to form a quadrupole sputtering device, so that the discharge tends to be stable. However, these devices have difficulty in obtaining a plasma region having a high concentration and a low deposition rate, and thus have not been widely used industrially.
