Embodiment Construction

[0020] The present invention will be further described below with specific embodiment, see figure 1 —4:

[0021] The oblique shaft oil-free compressor includes a cylinder 1, a piston 2, a connecting rod 3, an axle box 4, a drive shaft 5 and a swing plate 6, and the connecting rod 3 and the swing plate 6 are rotatably connected to each other using a ball joint structure 7. Connected, the connecting rod 3 is driven by the wobble plate 6 to move, the connecting rod 3 drives the piston 2 and causes the piston 2 to reciprocate relative to the cylinder 1; 8. The axis O2 of the inclined shaft 8 is not parallel to the axis O1 of the drive shaft 5 (see image 3 ); the swing plate 6 is rotatably sleeved on the inclined shaft 8 through at least one rolling bearing 9a and at least one thrust bearing 10 (see figure 1 ), the swing plate 6 is driven by the drive shaft 5 to move; a limited rotation mechanism is set between the swing plate 6 and the axle box 4, and the limited rotation mecha...

Abstract

The invention belongs to the technical field of compressors, and provides an oblique-shaft type oilless compressor which comprises a cylinder, a piston, a connection rod, a shaft box, a driving shaft and a wobble plate. The driving shaft and an oblique shaft are used for driving the wobble plate so as to drive the connection rod and the piston to move in a reciprocating mode. A rotation limiting mechanism comprising a wobble plate pin, a swinging arm and shaft box pins is used for limiting the rotation angle of the wobble plate around the axis of the driving shaft. Since the wobble plate is sleeved on the oblique shaft in a rotating mode, lubrication oil or an oil bearing structure can be conveniently sealed between the wobble plate and the oblique shaft. All movement matching pairs of the rotation limiting mechanism can be connected through rotation structures, so that the oil bearing structure can be used, and the shaft box of the compressor does not need to store liquid lubrication oil, in other words, the oblique-shaft type oilless compressor eliminates the potential safety hazard that the lubrication oil splashes to the wall face of the cylinder so that oilless work-medium output of the compressor can be achieved in a reliable mode.

Description

technical field [0001] The invention belongs to the technical field of compressors, and relates to an inclined-axis compressor, in particular to an inclined-axis oil-free compressor which utilizes an inclined-axis mechanism to realize the reciprocating motion of a compressor piston-and-rod assembly. Background technique [0002] The existing swash plate compressor has the advantages of compact structure and good dynamic balance performance, and has been widely used in the field of compression of various gaseous working fluids such as natural gas, air, and steam. The principle of this type of compressor is that the prime mover drives a swash plate to perform a fixed-axis rotary motion around the axis of the rotating shaft, and then the swash plate drives a matching wobble plate to perform oscillating motion. The direction forms reciprocating movement and drives the connecting rod through the ball joint or sliding shoe structure, and then the connecting rod drives the piston t...
