Abstract
The utility model discloses a combining piece of a rotor of a spinning unit and belongs to components of a rotor spinning machine. The conventional rotor of the spinning unit is liable to abrade during high-speed spinning. The combining piece comprises a high-carbon-chromium bearing steel cuppy rotor base body and a high carbon steel rotor rod core body, wherein a condensation groove is formed in the bottom edge of the inner chamber of the rotor base body; a through hole is formed in the center at the bottom of the inner chamber of the rotor base body; the rotor rod core body is fixedly arranged in the through hole in a penetrating manner; a plurality of layers of CVD (chemical vapor deposition) films are arranged on the inner chamber surface and the outer surface of the rotor base body; and a plurality of layers of same CVD films are arranged on the surface of the rotor rod core body. As the CVD films are arranged on the surfaces of the rotor and a rotor rod, the rigidity and the abrasive resistance are improved, so as to prolong the service life of the rotor.
Description
Technical field
The utility model belongs to the rotor spinning machine parts, and is especially relevant with a kind of revolving cup conjunction that is used for the rotor spinning machine spinning organ.
Background technology
The device of rotor for spinning conjunction comprises revolving cup and cup bar, and the intracavity bottom edge of the cup-shaped matrix of revolving cup is provided with collection surface, and the intracavity bottom center of matrix is provided with through hole, and the cup bar fixedly is threaded onto in this through hole.Present rotor spinning machine rotor speed can reach more than 100,000 rev/mins, and revolving cup is when rotating so at a high speed, and revolving cup is easy to wearing and tearing with cup bar surface, so require revolving cup and cup bar surface to have very high ABRASION RESISTANCE.Tradition device of rotor for spinning conjunction adopts hard anodizing to handle or plating nickel on surface improves case hardness and ABRASION RESISTANCE; But; Such revolving cup conjunction 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 conjunction is short partially.
The utility model content
The purpose of the utility model is exactly than higher defective a kind of device of rotor for spinning conjunction with surperficial high rigidity and high-wearing feature to be provided in order to overcome existing device of rotor for spinning conjunction wear rate when the high-speed spinning.
For this reason; The utility model adopts following technical scheme: the device of rotor for spinning conjunction; Comprise cup-shaped revolving cup matrix of high-carbon-chromium bearing steel and high-carbon steel bowl bar core body; The intracavity bottom edge of revolving cup matrix is provided with collection surface, and the intracavity bottom center of revolving cup matrix is provided with through hole, and cup bar core body fixedly is threaded onto described through hole; Revolving cup 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: described cup bar core surface is provided with the identical CVD of multilayer (chemical vapour deposition (CVD)) and films.
As technique scheme replenish and perfect, the utility model also comprises following additional technical feature.
It is three layers that described CVD films, and is respectively from inside to outside: TiC layer, TiCN layer, TiN layer.
Described TiC layer thickness is 1～3um.
Described TiCN layer thickness is 1～4um.
Described TiN layer thickness is 1～4um.
Use the utility model can reach following beneficial effect: film through being provided with multilayer CVD at revolving cup with cup bar surface, hardness has been reached about HV2000, improve nearly 3 times, ABRASION RESISTANCE improves 5 times, has prolonged the service life of revolving cup greatly.
