Description
Technical field
The present invention relates to a kind of oil-free scroll formula bearing of compressor lubricating structure, more particularly to the lubricating machine
The oil injection structure of structure.
Background technology
After oil-free scroll formula compressor uses one section of period, it is necessary to be injected into lubricant grease and prevent certainly
Enter the work of line period maintenance among the bearing for turning.But the oiling mode of prior art is to need to disassemble
After the part of the fixed scroll of body, can be directed to the pump nozzle of bearing carries out the carrying out of oiling.
As shown in figure 1, being that prior art oil-free scroll formula compressor uses a kind of more bearing lubrication
Oil injection structure.Need first to remove the parts such as left half side fixed scroll and wind scooper in figure (in figure
Remove) after, using oiling instrument 39 by lubricant grease entering through pump nozzle 35 and bearing mounting base
Oilhole 34 is injected into the envelope that bearing mounting base 33, crank axle 36 and the three of clutch shaft bearing 37 are collectively forming
In oil cavity 38, and then lubricating grease is set to reach in clutch shaft bearing 37 and the cavity of second bearing 16, to reach
To the lubrication of bearing, mark 17 represents housing in figure.
Fixed scroll is the critical component of oil-free scroll, and its fitted position precision is, it is necessary to have certain
The professional of oil-free scroll machine assembling experience can just be carried out, due to completing the work of machine general maintenance
In, it is necessary to carry out complexity disassembles assembling process, increased maintenance time.
The content of the invention
The technical problem to be solved in the invention there is provided a kind of oil-free scroll formula bearing of compressor lubrication
Mechanism, it is intended to solve the problems, such as above-mentioned.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：
The present invention includes：Housing, clutch shaft bearing and second bearing；Also include：It is outer bearing carrier, solid
Determine scrollwork, screwed hole, unthreaded hole, crank axle, bearing block；Described outer bearing carrier, housing and fixation
Scrollwork constitutes a closed cavity；Described clutch shaft bearing and second bearing are in the closed chamber
In body；Described crank axle makes hollow shaft, and the hollow shaft is made up of successively screwed hole and unthreaded hole；Institute
The bearing block stated constitutes cavity with crank axle；Described screwed hole, unthreaded hole and cavity are constituted and are communicated to
The passage of the lubrication portion of clutch shaft bearing and second bearing；Also include：One fills lubricating oil mechanism；Institute
The lubricating oil mechanism that fills stated is connected with screwed hole.
Compared with prior art, the beneficial effects of the invention are as follows：Because attended operation process is not always appointed
What disassembles action, alleviates attendant's workload, also reduces the operating experience requirement of attendant.
The quality of rotatable parts is reduced, compressor whole efficiency is improved to a certain degree.
Brief description of the drawings
Fig. 1 is the oil injection structure of prior art oil-free scroll formula bearing of compressor.
Fig. 2 is an embodiment of the present invention structural representation.
Fig. 3 is another kind example structure schematic diagram of the invention.
Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
From Fig. 2, Fig. 3：The present invention includes：Housing 9, clutch shaft bearing 6 and second bearing 7；
Also include：Outer bearing carrier 2, fixed scroll 10, screwed hole 4, unthreaded hole 5, crank axle 12, bearing block
8；Described outer bearing carrier 2, housing 9 and fixed scroll 10 constitute a closed cavity；Described
Clutch shaft bearing 6 and second bearing 7 are in the closed cavity；Described crank axle 12 is made
Hollow shaft, the hollow shaft is made up of successively screwed hole 4 and unthreaded hole 5；Described bearing block 8 and crank
Axle 12 constitutes cavity 11；Described screwed hole 4, unthreaded hole 5 and cavity 11 are constituted and are communicated to first
The passage of the lubrication portion of bearing 6 and second bearing 7；Also include：One fills lubricating oil mechanism；Institute
The lubricating oil mechanism that fills stated is connected with screwed hole 4.
As shown in Figure 2：Described fills lubricating oil mechanism for a set screw 3 and L-type spanner 1；Institute
The set screw 3 stated is placed in screwed hole 4, and L-type spanner 1 can adjust the position of set screw 3.
As shown in Figure 3：Described fills lubricating oil mechanism for a pump nozzle 13 and nozzle 14；Described
Pump nozzle 13 is placed in screwed hole 4.
Operation principle of the invention is as follows：
Carry out axially position by the anti-stop scrollwork rotation of crank axle 12 and to dynamic scrollwork, and crank axle 12
The cooperation for passing through clutch shaft bearing 6 and second bearing 7 with dynamic scrollwork bearing block, clutch shaft bearing 6 and
Second bearing 7 is in the airtight cavity that housing 9 and fixed scroll 10 are formed.Crank axle 12 is done
Into hollow shaft, hollow cavity is made up of screwed hole 4 and unthreaded hole 5.Grease is filled in hollow cavity, and is locked
Upper set screw 3, so that when to machine maintenance, can be stopped payment by using the regulation of L spanners 1
Screw 3 is along arrow movement (Fig. 2) so that the lubricating grease in screwed hole 4 and unthreaded hole 5 is arranged to cavity 11,
And then reach in the cavity of clutch shaft bearing 6 and second bearing 7, so as to realize clutch shaft bearing 6 and
The purpose of the lubrication of second bearing 7.
Set screw 3 in Fig. 2 can also be replaced by the present invention pump nozzle 13 in lower Fig. 3, be led to
Cross nozzle 14 to refuel, so as to also realize the purpose of clutch shaft bearing 6 and the lubrication of second bearing 7.
