The metal snap ring is provided with more than one elastic piece or clamping jaw which is arranged on the edge of the metal snap ring. According to the rotor cover assembly used for the rotor type compressor, the metal snap ring and the wafer cover are in integral injection molding, the metal snap ring solves the problem of unstable connection of plastic materials and the motor rotor, the connection reliability is high, and finally, the rotor cover assembly is buckled, connected and fixed with the motor rotor by the metal snap ring; and meanwhile, the wafer cover is made of plastics and can be manufactured to be various functions of shapes, and the oil output quantity of the compressor can be lowered. The rotor cover assembly has the characteristics that the structure is simple and reasonable, the cost is low, the service life is long, and the processing and the production are convenient.
Description
Technical field
The utility model relates to a kind of rotor cover assembly that is used for rotor-type compressor.
Background technique
Rotor-type compressor of the prior art referring to Fig. 1-shown in Figure 2, comprises that housing 1, housing internal fixation are provided with motor stator 2, are positioned at the rotor 3 and the compression assembly 4 at motor stator middle part, and compression mechanical part centre-crank shaft 4.1 links to each other with rotor.Drive the rotation compression refrigerant at compression assembly 4 centers by rotor, the electromagnetism gap is arranged between rotor and the stator, the air-flow of compressor upwards flows out from the electromagnetism gap, in order to reduce to tell oil mass, generally is fixedly connected with rotor disk lid 51 on rotor top.Rotor disk lid is generally disc; Its purpose is: the one, stop of the ejection of the oil of rotor center through the bent axle center hole; The 2nd, the rotor disk covers with the rotor high speed rotating, and also rotation is mobile together to drive the air-flow that flows up from the electromagnetism gap, makes that the mist of oil in the air-flow is thrown on the compressor housing with airflow breakaway under action of centrifugal force; Form Oil-gas Separation, reduce to tell oil mass.
Being made of metal of existing rotor disk lid; Its cost is higher; Simultaneously tell oil mass for rotor disk lid can better play effect and the reduction that rough air forms centrifugal rotation, rotor disk lid will be formulated more complicated structure, and the stamping process of existing metal panel beating can't satisfy the demands.Therefore, be necessary to do further improvement and perfect.
The model utility content
The purpose of the utility model aims to provide the rotor cover assembly that is used for rotor-type compressor that oil mass is told in a kind of simple and reasonable, with low cost and effective improvement, to overcome deficiency of the prior art.
A kind of rotor cover assembly that is used for rotor-type compressor by this purpose design comprises the rotor cover assembly that is arranged at rotor top, and its structure characteristic is that said rotor cover assembly comprises disk lid and metal clasp; The corresponding metal clasp of rotor is provided with draw-in groove, and the rotor cover assembly is fixed through metal clasp and the mutual buckle of rotor.
Said metal clasp is provided with more than one shell fragment or claw, and shell fragment or dog rings winding place on the edge of metal clasp; Metal clasp embeds or imbeds on the bowl-shape joint.
Said disk lid is plastic part, and metal clasp and disk lid are integrated injection molding, and shell fragment or claw expose to disk and cover; The rotor cover assembly is coaxial setting up and down with rotor.
Said disk lid comprises bowl-shape joint and the round plate that is attached thereto, and round plate is provided with more than one jut; This jut is arch or semicircle, and jut is uniformly distributed on the end face of round plate.
The utility model is through being integrated injection molding with metal clasp and disk lid; Metal clasp has solved plastic article and unstable problem of being connected of rotor; Connection reliability is high, realizes that finally the rotor cover assembly fixes through metal clasp and the mutual buckle of rotor; The disk lid can be processed the shape that satisfies various functions for plastic part simultaneously, and the arch jut on the round plate is easy to molding and forming, and the function that rough air forms centrifugal rotation is excellent, can reduce the oil mass of telling of compressor significantly through experimental verification; The characteristics that it has simple and reasonable, with low cost, long service life and is convenient to processing.
