The utility model discloses a miniature wind cooling reciprocating piston non-lubricated compressor, aiming at solving problems of poor radiating condition, high operating temperature, easy damage and no continual long term operation of the connecting rod small end bearing of current non-lubricated compressors. The utility model includes a non-oil cylinder (1), a non-oil piston (2), a connecting rod (12), and a crankshaft box(13). The non-oil piston (2) is installed in the non-oil cylinder (1). The characters are that the non-oil piston (2) is connected with the connecting rod (12) by a crosshead (4); the big head of the connecting rod (12) extends into the crankshaft box (13) and is connected to the driving crankshaft. One end of the crosshead (4) which is connected to the connecting rod (12) is disposed in the midbody guidance cylinder (7) installed between the non-oil cylinder (1) and a crankshaft box (13). The midbody guidance cylinder (7) is provided with a breathing hole (15). Thus, the connecting rod small end bearing has a low temperature rise and good radiation, and can work continually for long term.
Description
Technical field
The utility model relates to a kind of light duty compressor, especially a kind of small-sized oilless compressor, specifically a kind of small-sized air-cooled reciprocating piston non-oil lubricating compressor.
Background technique
As everyone knows, oil-free compressor need not refuel, and compressed medium and environment can not be subjected to oil pollution, and operating cost is low, has obtained the extensive of application in industries such as food, medicine, electronics, chemical industry, military projects, and the social demand amount is huge, and growing.But the running temperature height of traditional oil-free compressor, connecting rod small end needle bearing radiating condition is poor, and cunning fat easily runs off or is aging, causes bearing to damage in early days.Therefore, at present installed power can only intermitten service greater than the oil-free compressor of 11KW, when needs move continuously, and must be with two chaptrel stream work.Even take turns to operate, the life-span is not high yet, so limited applying of oil-free compressor.
Summary of the invention
The purpose of this utility model is poor because of radiating condition at the small end bearing of existing small-sized oil-free compressor existence, the running temperature height, fragile, and the problem that can not work long hours continuously, design little, the good heat dissipation of a kind of small end bearing temperature rise, the small-sized air-cooled reciprocating piston non-oil lubricating compressor of continuous operation for a long time.
The technical solution of the utility model is:
A kind of small-sized air-cooled reciprocating piston non-oil lubricating compressor, comprise no oil gas cylinder 1, no oily piston 2, connecting rod 12, crankcase 13, not having oily piston 2 is installed in the no oil gas cylinder 1, it is characterized in that described no oily piston 2 links to each other with the microcephaly of connecting rod 12 by crosshead 4, the major part of connecting rod 12 stretches in the crankcase 13 and links to each other with the driving bent axle, the end that crosshead 4 links to each other with connecting rod 12 is in the middle body guiding cylinder 7 that is installed between no oil gas cylinder 1 and the crankcase 13, and middle body guiding cylinder 7 is provided with spiracle 15.
One end of described crosshead 4 stretches in the no oil gas cylinder 1 and links to each other with no oily piston 2, the other end of crosshead 4 is arranged in body guiding cylinder 7, wrist pin 9 is installed on it, bearing 10 is installed on the wrist pin 9, the microcephaly of connecting rod 12 is sleeved on the bearing 10, and the major part of connecting rod 12 stretches in the crankcase 13 and links to each other with the driving bent axle.
In order further to reduce not have heat that oily piston 2 work produce by the transmission of crosshead 4 to the small end bearing part, the utility model is equipped with thermal insulating pad 3 between no oily piston 2 and mating face that crosshead 4 links to each other.
Similarly, transmit to middle body guiding cylinder 7 in order to reduce not have the heat that oil gas cylinder 1 produces, the whole temperature rise of body guiding cylinder in causing, the utility model is equipped with thermal insulating pad 6 on no oil gas cylinder 1 and middle body lead the mating face of cylinder 7.
For the heat dispersion of body guiding cylinder 7 in improving, the utility model is provided with the middle body cavity 14 that communicates with described spiracle 15 in the outside of middle body guiding cylinder 7, and breathing circuit filter 8 is installed on the body cavity 14 in this.
Be arranged in crosshead 4 on the end of body guiding cylinder 7 guide sleeve of being made by self lubricating material 5 is installed.
The utlity model has following advantage:
The needle bearing radiating condition that the utility model has solved in the existing small-sized oilless compressor connecting rod small end hole is poor, the running temperature height, and lubricating grease runs off easily and lost efficacy, and needle bearing is damaged in early days, the problem that machine can not move continuously and rate of fault is high.It is by on the basis of former conventional structure, increased middle body guiding cylinder 7, crosshead 4 and technical measures such as thermal insulating pad 6,3, increase breathing circuit filter 8 have been housed between junction plane, make heat and connecting rod 12 that no oil gas cylinder 1 produces in the course of the work isolate, roller bearing in the connecting rod small end hole holds 10 like this, heat radiation is good, and temperature is low.And by the cover made from lubricious material is housed to cover 5 in the lining portion of crosshead 4, the lateral force of bearing connecting rod 12 makes 2 in no oily piston bear axial force, reduces friction and wear greatly and generates heat.Thoroughly overcome completely without oily machine running temperature height, the flimsy defective of connecting rod small end needle bearing.
