Abstract
The utility model discloses a spinning rotor for a rotor spinning device and the spinning rotor is a component for a rotor spinning machine. While a conventional spinning rotor for a rotor spinning device is characterized by high wear rate in high-speed spinning processes, the spinning rotor in the utility model is characterized in that the spinning rotor comprises a cup-shaped GCr15 base body, wherein a coagulation groove is arranged at the edge of the base part of the inner cavity of the base body, a via hole for rotor rod installation is arranged at the base part center of the inner cavity of the base body, multiple CVD (chemical vapor deposition) coatings are arranged on the surface of the inner cavity of the base body and the outer surface of the base body, and a diamond-like nanometer coating layer is arranged on the CVD coatings. Through arrangement of multiple CVD coatings on the surface of the spinning rotor, the small dents on the surface of the CVD coating layer can be filled. Therefore the spinning rotor is advantaged by smoother surface, improved wear-resisting capability, reduced surface friction, and prolonged service life of the spinning rotor.
Description
Technical field
The utility model belongs to the rotor spinning machine parts, especially with a kind of to be used for rotor spinning machine spinning organ cup relevant.
Background technology
The spinning principle of rotor spinning machine is that resultant yarn is drawn in the fiber that disperses cohesion back twisting in the collection surface that rotates revolving cup at a high speed; Present rotor spinning machine rotor speed can reach more than 100,000 rev/mins; Revolving cup is when rotating so at a high speed; Fiber and yarn are quite severe to the friction of revolving cup inner chamber, thus require the revolving cup surface particularly surface of internal cavity have very high ABRASION RESISTANCE.The tradition device of rotor for spinning adopts hard anodizing to handle or plating nickel on surface improves case hardness and ABRASION RESISTANCE; But; Such revolving cup case hardness is generally about HV800; When spinning for the high rotating speed more than 100,000 rev/mins, the wear rate on revolving cup surface is still than higher, and the service life of revolving cup is short partially.
The utility model content
The purpose of the utility model is exactly than higher defective a kind of rotor spinning device cup with surperficial high rigidity and high-wearing feature to be provided in order to overcome existing rotor spinning device cup wear rate when the high-speed spinning.
For this reason; The utility model adopts following technical scheme: a kind of rotor spinning device cup; Comprise cup-shaped GCr15 matrix, matrix intracavity bottom edge is provided with collection surface, and matrix intracavity bottom center is provided with through hole and is used for the mounting cup bar; Matrix surface of internal cavity and outer surface are provided with multilayer CVD (chemical vapour deposition (CVD)) and film, and it is characterized in that: be provided with eka-gold steel stone nano-film coating layer outside described CVD films.DLC has good properties: high rigidity, and low-friction coefficient, ABRASION RESISTANCE is good, and adhesion is big, and good thermal conductivity is arranged.
As technique scheme replenish and perfect, the utility model also comprises following additional technical feature.
It is three layers that described CVD films, and outwards is respectively from matrix: TiC layer, TiCN layer, TiN layer.
Described type of diamond nano-film coating layer formed by three layers, and outside CVD films course, be respectively: ground floor is a self-lubricating layer, and the second layer is a wearing layer, and the 3rd layer is anti-adhesive layer.
Use the utility model can reach following beneficial effect: through be coated with rete peripheral hardware type of putting diamond nano-film coating layer at revolving cup surface C VD, CVD is coated with the small depression of film surface fills, make the cup surface more smooth, thus more wear-resisting; And a type diamond nano-film coating has good thermal conductivity, has anti-cohesiveness, makes fiber yarn and cup mantle friction littler, has prolonged the service life of revolving cup greatly.
