Abstract
An oil-free lubricating compressor with the crank-slider reciprocating-piston includes a piston and a crank pin on the crank. The slider is fixed on the crank pin and in the frame. Two sides of the frame are connected with the piston rod symmetrically. The pistons are mounted at the end of the piston rod and in the cylinder.
Description
Technical field
The present invention relates to a kind of reciprocating piston oilless compressor, especially a kind of motion is not the non-lubricated compressor that adopts crank-link mechanism, specifically a kind of crank-sliding block reciprocating piston non-oil lubricating compressor.
Background technique
At present, need a large amount of oil-free compressors that use to carry out air feed in industries such as food, medicine, chemical industry, electronics, thus very huge to the requirement of oil-free compressor.The moving system of traditional reciprocating piston oilless compressor mostly is crank-link mechanism; In the microcephaly hole of connecting rod radial needle bearing is housed, link to each other with no oily piston by wrist pin, piston is arranged in cylinder during work, the radiating condition of connecting rod small end is very poor, the temperature height, the lubricating grease of radial needle bearing easily runs off, wears out, cause the early failue of needle bearing, and the interpolation of lubricating grease is very difficult, therefore at present power can not continuous operation greater than the reciprocating piston oil-free compressor of 11kW, and the life-span is short, has limited the performance of its proper function, has influenced the popularization and the application of oil-free compressor.
Summary of the invention
The objective of the invention is to design and a kind ofly utilize slide block and crank to rotatablely move to be transformed into the crank-sliding block reciprocating piston non-oil lubricating compressor of reciprocating full-oil-free lubrication.
Technological scheme of the present invention is:
A kind of crank-sliding block reciprocating piston non-oil lubricating compressor, comprise piston 9, crank pin 8, crank pin 8 is positioned on the crank, it is characterized in that being equipped with on the crank pin 8 slide block 6, slide block 6 is installed in the framework 1, the dual side-edge of framework 1 is symmetrically connected with piston rod 11, and piston 9 is installed on the rod end of piston rod 11, and piston 9 is installed in the cylinder 10.
The present invention has also further taked following technical measures:
Two slide blocks 6 are installed on the described crank pin 8, each slide block 6 is installed in each self-corresponding framework 1, the dual side-edge of each framework 1 all is symmetrically connected with piston rod 11, be equipped with on the rod end of piston rod 11 9, two frameworks 1 of piston separately the axis of two pistons 9 connecting of symmetry stagger mutually in the space and be in vertical distribution.
In framework 1, on two opposed inside faces identical linear motion guide rail 2 is installed all, is equipped with on the linear motion guide rail 2 and slide block 6 contacted straight line motion pads 3 with slide block 6 straight line movement directions.
Described linear motion guide rail 2 is the straight line motion roller guide, and described straight line motion pad 3 is a straight line motion needle roller pad.
Be connected with at framework 1 on the two side faces of piston 9 and be provided with some adjusting screws that connect to linear motion guide rail 2, spring 4 and adjusting screw 5 are installed in this adjusting screw, adjusting screw 5 spinnings are in regulating screw, one end and the adjusting screw 5 of spring 4 offset, and the other end and linear motion guide rail 2 offset.Effect by spring 4 applies pretightening force to linear motion guide rail 2 and slide block 6, thereby eliminates the assembling play of straight line motion pad 3, makes to-and-fro motion steadily not have impact.
Beneficial effect of the present invention:
1, owing to replace the connecting rod of traditional design, do not have the problem of connecting rod small end needle bearing, also do not have connecting rod to act on lateral thrust on the piston, thereby reliability height, life-span is long because of the early failue of overheated initiation with piston rod.
2, the kinematic pair of motion is rolling friction, so the efficient height, the life-span is long, reliability is high, obvious energy conservation.
3, the inertial force of the reciprocating part of traditional crank-link mechanism is with the whole balance of the method that adds equilibrium block, and motion of the present invention can fall this full balance of shaking force, so vibration severity and noise all are significantly less than conventional construction.

Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Shown in Fig. 2,3.
A kind of crank-sliding block reciprocating piston non-oil lubricating compressor comprises piston 9, crank pin 8, and piston 9 is installed in the cylinder 10, and crank pin 8 is positioned on the crank, and crank is driven by power mechanism and rotates; Two needle bearings 7 are installed on the crank pin 8, and each needle bearing 7 is installed in corresponding two slide blocks 6, has just constituted rolling friction pair between crank pin 8 and the slide block 6 like this, increases the service life.Each slide block 6 is installed in each self-corresponding framework 1, the dual side-edge of each framework 1 all is symmetrically connected with piston 9, two frameworks 1 axis of two pistons 9 connecting of symmetry separately stagger mutually in the space and be in vertical distribution cross or X-shaped structure, as shown in Figure 3.Two frameworks 1 with four pistons 9 be installed in four cylinders 10 on four mutually perpendicular attachment faces that are fixedly mounted on crankcase.In framework 1, on two opposed inside faces identical straight line motion roller guide 2 is installed all, is equipped with on the straight line motion roller guide 2 and slide block 6 contacted straight line motion needle roller pads 3 with slide block 6 straight line movement directions.Be connected with at each framework 1 on the two side faces of piston 9 and be provided with some adjusting screws that connect to straight line motion roller guide 2, spring 4 and adjusting screw 5 (as shown in Figure 2) are installed in this adjusting screw, adjusting screw 5 spinnings are in regulating screw, one end and the adjusting screw 5 of spring 4 offset, and the other end and straight line motion roller guide 2 offset.Effect by spring 4 applies pretightening force to straight line motion roller guide 2 and slide block 6, thereby eliminates the assembling play of straight line motion needle roller pad 3, makes to-and-fro motion steadily not have impact.
In addition, when specifically implementing, with the quantity of each framework 1 corresponding cylinder can be one, also can be more than one so that constitute the stage differential style piston-cylinder, piston and the quantity of cylinder can equate also can be unequal or identical.
It is same as the prior art that present embodiment does not relate to part.
