Abstract
The invention discloses a hollow bearing oiling structure for an oil-free scroll compressor, belonging to the technical field of compressors. According to the oiling structure, an oiling operation can be finished in case of no detachment of a machine, the operation and the maintenance are convenient, and maintenance expense and maintenance time can be saved and the cost can be reduced. The structure comprises an oiling hole which is formed along the axial direction of an eccentric shaft, and the oiling hole penetrates through the eccentric shaft, and thus the eccentric shaft is of a hollow structure; a bearing oiling chamber is formed at the inner end part of the eccentric shaft, and the oiling hole is communicated with the bearing oiling chamber; a fastening bolt for sealing the oiling hole, and a gasket are arranged at the outer end part of the eccentric shaft, and a rubber rod matched with the oiling hole is further arranged at the inner end part of the fastening bolt. The hollow bearing oiling structure for the oil-free scroll compressor disclosed by the invention is simple to operate, convenient to use, and suitable for bearing oiling for multiple compressors.
Description
Technical field
The invention belongs to Compressor Technology field, relate to a kind of oil-free turbo-compressor, especially a kind of bearing hollow oil injection structure of oil-free turbo-compressor.
Background technique
Scroll compressor mutually to be moved the compression square-cavity change being formed and reduce continuously from outside to inside by the paired helical being staggered 180 degree, reaches air-flow compression.In air-breathing, compression, exhaust work process, price fixing is fixed in frame, and Moving plate is driven by eccentric shaft and with anti-rotation mechanism restriction, around price fixing basic circle center, makes the plane rocking of very minor radius.Be from conventional the different of oscillating type compressor, two helical relative movement gaps are little but do not contact, and the linear velocity of two helical relative movement is lower.According to above principle, the feature of oil-free turbo-compressor does not have metal friction in compression chamber, and compressor noise is little, and the life-span is long.But the machining accuracy of apparent oil-free turbo-compressor is high, and manufacturing requirements is high.
The bearing of oil-free turbo-compressor is with grease lubrication, bearing is after use some cycles, need to fill grease to safeguard the normal operation of compressor, existing grease injection mode: one is undertaken grease-filled by machine apart, and can only complete in manufacturer, maintenance cost is high, safeguard not in time with inconvenience; Another kind completes greasing with grease gun oil hole on equilibrium block, and what this grease gun can not be firm is fixing, and operation inconvenience, also compressor will have been pulled down greasing, maintenance time is long.
Summary of the invention
Technical assignment of the present invention is the bearing hollow oil injection structure providing a kind of oil-free turbo-compressor for above-mentioned deficiency of the prior art, this oil injection structure can complete grease injection operation when the not teardown of engine, without the need to returning factory, easy to operate and be convenient to safeguard, simultaneously can maintenance cost saving and when safeguarding
Between, reduce costs.
The technical solution adopted for the present invention to solve the technical problems is:
The bearing hollow oil injection structure of this kind of oil-free turbo-compressor, is characterized in that, its structure comprises the oil hole axially arranged along eccentric shaft, and described oil hole, through described eccentric shaft, makes eccentric shaft be hollow structure; The inner end of described eccentric shaft is provided with bearing oil-filling cavity, and oil hole is connected with bearing oil-filling cavity; The outer end of eccentric shaft is provided with clamping bolt and the pad of shutoff oil hole, and the inner end of described clamping bolt is also provided with a rubber rod matched with oil hole.
Preferably, described rubber rod one end is provided with outside thread, and the inner end of clamping bolt is embedded with a groove, is provided with the internal thread matched with rubber rod outside thread in groove.
The present invention has following outstanding beneficial effect:
1, because described oil hole is through described eccentric shaft, eccentric shaft is made to be hollow structure; The inner end of described eccentric shaft is provided with bearing oil-filling cavity, and oil hole is connected with bearing oil-filling cavity; Outer end is provided with clamping bolt and the pad of shutoff oil hole, so it have employed hollow oil injection structure, can when not dismantling compressor, directly complete the injection of grease, and simple to operation, client can complete greasing voluntarily, and maintaining cost is low, and safeguard in time to there is good utilization and extention and be worth.
2, because the inner end of described clamping bolt is also provided with a rubber rod matched with oil hole, described rubber rod one end is provided with outside thread, the inner end of clamping bolt is embedded with a groove, the internal thread matched with rubber rod outside thread is provided with in groove, so it can after grease have been noted, crammed in oil hole by clamping bolt, and then can prevent the grease of annotating from passing back into oil hole, do not have lubrication, in order to avoid cause unnecessary waste, rubber rod is convenient to dismantle with being threaded of clamping bolt simultaneously.
