The invention relates to an oil-free lubrication linear compressor. The oil-free lubrication linear compressor is characterized by comprising a compression unit and a linear motor, wherein the compression unit comprises a cylinder assembly, a piston assembly, at least one plate spring, a plate spring bracket and a plurality of cylindrical springs, the linear motor is fixed by a bolt group which is used for connecting the plate spring bracket with a cylinder, one end of the piston assembly is connected with the plate spring, the other end of the piston assembly is arranged between the linear motor and the cylinder assembly, the cylindrical springs are arranged between the piston assembly and the cylinder assembly, and a piston is driven to do a straight reciprocating motion in the cylinder by a permanent magnet under the action of electromagnetic force of the linear motor, so as to compress a refrigerating medium. According to the linear compressor, the plate spring and the cylindrical springs are combined to support, so that the axial rigidity and the radial rigidity of the compressor are greatly increased; additionally, a gas bearing support technique is adopted, so that oil-free lubrication and gap sealing of the compressor are realized; the compressor has the characteristics of less friction resistance, low noise, compact structure and good stability.
Description
technical field [0001] The invention relates to a compressor, in particular to an oil-free lubricated linear compressor. Background technique [0002] In the traditional reciprocating compressor, the motor drives the crankshaft to rotate, and the connecting rod drives the piston to reciprocate up and down in the cylinder, and the suction, compression and discharge process of the working medium are completed through the cooperation of the suction and exhaust valves. The scroll compressor is composed of a fixed static disk and an eccentric rotating and translational moving disk. The two mesh with each other to form a compressible closed volume and compress the working medium. The rolling rotor compressor is a compressor with a closed volume composed of a fixed circular cylinder, rotor, exhaust valve, sliding vanes that are always attached to the outer surface of the rotor, and end covers on both sides. [0003] As mentioned earlier compressors are usually driven by rotary mot...
