Embodiment
Referring to figs. 1 through Fig. 6, a kind of two juxtaposed cylinders of the utility model is described further without oily fork compressor embodiment.
A kind of two juxtaposed cylinders is without oily fork compressor, bag crankcase 1, crankcase 1 upper end is fixed with cylinder 2, cylinder 2 upper end is fixed with valve plate and has cylinder cap, cylinder 2 is aluminum, its side is provided with radiating fin 3, is provided with two juxtaposed compression chambers 4 of array, is equipped with the oscillating bar assembly 5 be mated in compression chamber in cylinder 2.Oscillating bar assembly 5 is constrained in compression chamber 4, axially can only do up and down reciprocatingly swing along compression chamber 4.Oscillating bar assembly 5 comprises fork main body 51, bottom fork 52, leather cup 53, and the gland 54 of fixing leather cup forms, bottom fork main body 51 and fork, 52 surround a bearing bore caved in 6, bearing can be fixed on fork center by bearing bore 6, when can ensure to install, bearing is in the positive lower end at compression chamber center, locking nut 55 by bottom fork 52 and fork main body 51 combine, when locking nut 55 is not locked, bottom fork 52 and the installation circular hole that forms of fork main body 51 can become large a little, convenient to install.Be provided with bearing in bearing bore 6, oscillating bar assembly 5 is connected with bent axle 7 by bearing.Bent axle 7 drives oscillating bar assembly 5 to do axially lower swing pressurized air along compression chamber 4, and adjacent two oscillating bar assemblies 5 differ 1/2 cycle, when an oscillating bar assembly be positioned at compression chamber 4 start bottom up motion compresses air time, another oscillating bar assembly is in compression chamber 4 topmost and start air-breathing in compression chamber of down moving.Arrange bent axle 7 moment of rotation so steady, the inertial force of oscillating bar assembly 5 is cancelled out each other simultaneously, and efficiency is high, more steady during air compressor work, decreases noise and vibrations.Crankcase 1 substantially horizontal is fixedly installed crankshaft base 8, and arrange in crankshaft base 8 and be provided with two bearings, fixed by bent axle 7 by bearing, bent axle 7 one end is stretched out crankcase 1 and is connected with belt pulley 9.Bent axle 7 two ends are all fixed on crankcase 1, the bending resistance of bent axle 7 is improved, relative to the mounting type only having one end fixing, the vibrations produced when compressor operating is set like this and noise less, bent axle 7 drive oscillating bar assembly 5 move upward compressed air to do work time amount of deformation reduce, operate more steady.
Crankcase 1 side is provided with suction port 10 and filter 11, and the air entering crankcase 1, first through the filtration of filter 11, can improve the turbidity test of air, be provided with gas-entered passageway 12 in cylinder 2, and the air entered from suction port 10 enters compression chamber through gas-entered passageway 12.When oscillating bar assembly 5 moves downward air-breathing, extraneous cool air is sucked by the suction port 10 from crankcase 1 side, and finally enter compression chamber 4 through gas-entered passageway 12, cool air has taken away the temperature in crankcase 1 in the process, and bearing is cooled, improve the life-span of bearing.
When belt pulley 9 driving crank 7 rotates, the eccentric shaft on bent axle 7 drives oscillating bar assembly 5 in cylinder compression chamber 4, do the to-and-fro motion not needing lubricant oil, achieves the air-breathing needed for compression and exhaust process; The friction of oscillating bar assembly 5 in cylinder compression chamber is realized by the leather cup 53 of selflubricating; Leather cup 53 is made up of filling polytetrafluoro material, has good self lubricity and pliability, when compressing because gas pressure opens, being close to cylinder, effectively reducing leakage, raising the efficiency.When belt pulley 9 rotates, the fan blade 13 be arranged on belt pulley 9 also rotates and forms air-flow, and the air-flow of formation is directed to cylinder 2; force cooling cylinder 2, reduce cylinder 2 temperature, protection leather cup 53; cylinder 2 outer wall is provided with radiating fin 3, adds heat diffusion area, strengthens radiating effect.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
