Description
Technical field
The utility model belongs to field of mechanical technique, is related to air compressor and vacuum pump.
Background technique
Air compressor machine is the main body in compressed air source unit, it is by prime mover（Usually motor）Mechanical energy be converted into gas
The device of pressure energy is the pressure generator of compressed air.Air compressor machine is widely used in military, civilian, factory and enterprise, vehicle
The fields such as ship traffic, mine smelting, construction and decoration, household electrical appliance, automobile.Therefore, social development, people's lives are not all from
Open air compressor machine.
Currently used air compressor is mainly piston type air compressor and screw air compressor, although this two
Kind air compressor machine has their own advantages, but also all there is certain shortcoming.For example, piston type air compressor mainly utilizes motor shaft band
The rotary motion of crankshaft in motivation head, band piston are waved reciprocating and are compressed to cylinder interior gas, and piston is easily ground
It damages and stability is poor；Screw-rod air compressor cylinder internal rotor engaging friction, velocity of rotation is fast, and calorific value is big, does not require nothing more than material
The wearability of material is very high, and also needs a large amount of cutting oil when in use, and finally also needs to carry out oil gas point
From, therefore cause screw compressor energy consumption height, higher cost, complicated for operation, maintenance and the difficulty of maintenance larger.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, work for the above-mentioned problems in the prior art
Make the compression set of reliable, energy-efficient oil-free lubrication.
The purpose of this utility model can be realized by the following technical scheme：A kind of compression set of oil-free lubrication, it is special
Sign is, including cabinet, two symmetrically arranged cylinders being installed on cabinet, and is set to direct by motor shaft in cabinet
The cam for driving rotation is provided with cylinder cap on the cylinder, is provided with piston assembly in cylinder, the piston assembly with it is convex
Take turns several bearings being equipped in corresponding end for cam contact, and piston assembly close to the end of cam have to
The piston seat of outer radial protrusion, two are connected with respect between the piston seat in piston assemblies by four guide posts；When motor shaft drives
When cam rotates, the bearing that the driving of raised arcwall face is mounted in piston assembly on cam makes piston assembly in respective cylinder
Inside do straight reciprocating motion.
In a kind of compression set of above-mentioned oil-free lubrication, the piston assembly is offered close to the end of cam
For the notch of cam rotation.
In a kind of compression set of above-mentioned oil-free lubrication, it is total that the bearing by piston pin is fixedly installed in piston
At interior.
In a kind of compression set of above-mentioned oil-free lubrication, four guide posts are located at four sides of piston seat
At angle, and fixed by adjusting bolt.By adjusting the contact gap of adjustment bolt adjustable bearing and cam.
When compared with prior art, using the compression set of this oil-free lubrication, when motor shaft band moving cam rotates, cam
Outer arcuate face contacted with the bearing outer ring being mounted in piston assembly, drive piston assembly in respective cylinder same flat
Face linearly moves back and forth simultaneously, and air compressor machine continuous-stable is made to work, and largely reduces noise caused by air compressor machine, mentions
The high efficiency of air compressor machine, and internal structure is simple, effectively reduces the volume of air compressor machine, alleviates the weight of air compressor machine.

Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, Figure 2, Figure 3 shows, the straight belt handpiece of air compressor of this cam 3 include cabinet 1, be installed on cabinet 1 two
A symmetrically arranged cylinder 2, and it is set to the cam 3 for directly driving rotation in cabinet 1 by motor shaft, it is provided on cylinder 2
Cylinder cap 4 is provided with piston assembly 5 in cylinder 2, is equipped in piston assembly 5 and the corresponding end of cam 3 and contacts for cam 3
Several bearings 6, and piston assembly 5 close to the end of cam 3 have outward radial protrusion piston seat 7, two relatively live
It fills in and is connected between the piston seat 7 in assembly 5 by four guide posts 8；It is raised on cam 3 when motor shaft band moving cam 3 rotates
The bearing 6 that arcwall face driving is mounted in piston assembly 5 makes piston assembly 5 do straight reciprocating motion in respective cylinder 2.
In order to keep the bearing 6 in the straight belt handpiece of air compressor of this cam 3 easy for installation, 3 rotary work of cam is not obstructed,
Its piston assembly 5 offers the notch 9 rotated for cam 3 close to the end of cam 3, and bearing 6 passes through the fixed peace of piston pin 10
Loaded in piston assembly 5.
It further describes in detail, four guide posts 8 in the straight belt handpiece of air compressor of this cam 3 are located at four of piston seat 7
