Description
Technical Field
The utility model belongs to the technical field of air compressors, and particularly relates to a five-cylinder oil-free air compressor.
Background
At present, the working mode of the oil-free air compressor is that a motor is used for driving a crankshaft and a connecting rod to work, and pistons in a cylinder are driven to reciprocate through communication to do work; the existing crankshaft is generally provided with a fixed wheel, and the fixed wheel has the function of improving the working stability of the crankshaft so as to prevent the crankshaft from generating excessive vibration in centrifugal rotation; however, due to the presence of the fixed sheave, the stress points on the crankshaft are concentrated on the fixed sheave, which easily causes the crankshaft to be broken at this position due to excessive compression; there is a need for improvement.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provide the five-cylinder oil-free air compressor which has the characteristics of ensuring the working stability of a crankshaft and avoiding the breakage of the crankshaft.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: the five-cylinder oilless air compressor comprises a cylinder body and a power assembly, wherein a motor assembly is arranged in the cylinder body and is respectively connected with the power assemblies positioned at two sides of the cylinder body through rotating shafts; the power assembly comprises a driving connecting rod, a crankshaft, a crankcase, a crankshaft cover, a movable wheel and five cylinder assemblies, wherein the crankshaft cover is covered on the side surface of the crankcase; one end of the crankshaft is connected with the rotating shaft through a coupler, and the other end of the crankshaft passes through the driving connecting rod and is positioned on the crankshaft cover; the driving connecting rod is positioned in the crankcase, and the connecting rod parts on the driving connecting rod are respectively connected with pistons in the five cylinder assemblies so as to do work in the driving connecting rod; the cylinder assembly is positioned outside the crankcase and connected with an external air source through an air filter; the movable wheels are positioned on the crankshaft and are opposite to the fixed wheels on the crankshaft in position so as to synchronously rotate, and the movable wheels and the fixed wheels are respectively positioned on two sides of the driving connecting rod.
The movable wheel is arranged on the crankshaft in an adjustable way.
By adopting the structure, compared with the prior art, the utility model has the following advantages: according to the utility model, the movable wheel is arranged on the crankshaft, and the movable wheel and the fixed wheel are respectively positioned at two sides of the driving connecting rod, so that the center between the movable wheel and the fixed wheel is concentrated on the crankshaft positioned in the driving connecting rod, the pressure is prevented from being concentrated at one side, and the phenomenon of shaft breakage is avoided.

Detailed Description
The following description is of the preferred embodiments of the present utility model, and is not intended to limit the scope of the utility model, which is further described with reference to the accompanying drawings and examples.
Examples, see fig. 1-2: the utility model provides a five jar oilless air compressor machine, includes cylinder body 10 and power assembly, and the inside hollow structure that is of cylinder body 10 has motor assembly in its inside, and motor assembly is connected with the power assembly that is located the cylinder body 10 both sides respectively through the pivot to drive power assembly work through it. The power assembly comprises a driving connecting rod 20, a crankshaft 21, a crank case 22, a crank cover 23, a movable wheel 24 and five cylinder assemblies 25, wherein the crank cover 23 covers the side surface of the crank case 22 so as to seal the interior of the crank case. One end of the crankshaft 21 is connected with the rotating shaft through a coupler, and the other end of the crankshaft passes through the driving connecting rod 20 and is positioned on the crankshaft cover 23; the driving connecting rod 20 is positioned in the crankcase 22, and the connecting rod parts on the driving connecting rod 20 are respectively connected with pistons in five cylinder assemblies 25; in operation, the motor assembly drives the crankshaft 21 to rotate, and the connecting rod 201 on the driving connecting rod 20 drives the piston to do work up and down in the cylinder assembly 25 through the rotation of the crankshaft 21. The cylinder assembly 25 is located outside the crankcase 22 and is connected with an external air source through an air filter 26, an air inlet chamber and an air outlet chamber are arranged in the cylinder assembly 25, and air in the air inlet chamber is discharged from the air outlet chamber after being compressed again through the work of the piston so as to be used. The running wheel 24 is located on the bent axle 21 and is relative with the tight pulley 27 position on the bent axle 21 in order to rotate in step, and running wheel 24 and tight pulley 27 are located the both sides of initiative connecting rod 20 respectively, and specifically, running wheel 24 is adjustable setting on bent axle 21, and its relative position with tight pulley 27 can be adjusted according to the user demand in use to guarantee that the line center of running wheel 24 and tight pulley 27 is located the shaft hole of initiative connecting rod 20, avoided the excessive concentration of pressure, make the operation more steady.
