As shown in Figures 1 to 4, in the screw compressor of embodiment one, dynamic disk component includes drive disk 20 and dynamic vortex
Disk 30, quiet disk component include bracket 10 and fixed scroll 80.Wherein, orbiter 30 is fixedly connected on drive disk 20, driving
Disk 20 is rotatably arranged on bracket 10, and engagement forms the compression of multiple crescent shapes between orbiter 30 and fixed scroll 80
Chamber.Drive disk 20 includes first bearing chamber 22, and orbiter 30 includes first passage 31 and oil injection structure 32, first passage 31
Outlet is arranged in orbiter 30 and is connected to towards on the end face of drive disk 20 and with first bearing chamber 22, the entrance of first passage 31
It is arranged on end face of the orbiter 30 far from drive disk 20, oil injection structure 32 is arranged in first passage 31.Fixed scroll 80
On be provided with the first oil filler point 82, the first oil filler point 82 being capable of position corresponding with first passage 31.
Using the technical solution of the present embodiment, in screw compressor operating.Orbiter 30 is relative to fixed scroll 80
It is moved along circular trace is preset, at the time of as shown in Figure 1, the first oil filler point 82 can be corresponding with first passage 31, makes oiling
The structures such as pipe can from the right side of Fig. 1 by the first oil filler point 82 be connect with oil injection structure 32 and to 22 oiling of first bearing chamber with
Lubricate first bearing 61.
Preferably, as shown in Fig. 2, the oil injection structure 32 of the present embodiment does not protrude from the entrance of first passage 31.Above-mentioned knot
Oil injection structure is embedded in orbiter 30 by structure, to avoid oil injection structure and the scraping collision of surrounding other structures, causes structural failure.
In other embodiments, oil injection structure also can be set on drive disk, and correspondingly, oil filler point also can be set
Make the correspondence of oil filler point and oil injection structure on bracket, realizes that oiling equipment passes through quiet disk component and to the first axle in quiet disk component
Chamber oiling is held, oil injection operation is simplified.
Meanwhile oil injection structure 32 is moved on orbiter 30 from drive disk 20 and is arranged in first passage by the present embodiment
In 31, the problem of drive disk needs for oil injection structure reserved space is evaded, has made the edge ruler of drive disk 20 Yu orbiter 30
It is very little can be roughly the same, alleviate the weight of drive disk 20, in this way when drive disk 20 and orbiter 30 rotate, drive disk 20
Smaller with the inertia of orbiter 30, the centrifugal force of generation and vibration are smaller, are conducive to control and can extend screw compressor
Service life.

Materials and weight further reduce inertia when drive disk 20 and the rotation of orbiter 30.
Further, as shown in Figure 2 and Figure 4, the present embodiment is the weight for mitigating drive disk 20, the bottom of first bearing chamber 22
Wall only remains the circular step for abutting fixed first bearing 61, and such structure is solid in drive disk 20 and orbiter 30
Also the space of bigger receiving lubricant grease is capable of forming when connecting surely.
Preferably, as shown in figure 3, the orbiter 30 of the present embodiment further includes multiple lugs 34, lug 34 and arm 21 1
One is arranged in correspondence with, and each lug 34 is provided with a first passage 31.Lug 34 is provided only on necessary position and realizes in this way
The arrangement of being connected and fixed between orbiter 30 and drive disk 20 and oil injection structure 32 eliminates unnecessary positional structure
Weight.
As depicted in figs. 1 and 2, the screw compressor of the present embodiment further includes separation structure 40 and the first crankshaft 50.Wherein,
Separation structure 40 is arranged between bracket 10 and drive disk 20, and the first crankshaft 50 is threaded through in separation structure 40.Separation structure 40
First bearing chamber 22 is formed between drive disk 20, second bearing chamber is formed between separation structure 40 and bracket 10, on bracket 10
It is provided with the second channel 11 being connected to second bearing chamber.Connection first bearing is formed between first crankshaft 50 and separation structure 40
The communicating passage 64 of chamber 22 and second bearing chamber.
First bearing chamber 22 is connected to second bearing chamber by communicating passage 64, forms a cavity, to scroll compression
When contracting machine injects lubricant grease, lubricating oil successively can be injected to first bearing chamber 22 and second bearing chamber by oil injection structure 32
Rouge saves the time of primary replacement pouring orifice dismounting oiling equipment, improves oiling efficiency to a certain extent.Meanwhile the
Two inlet and outlet of one channel 31 and second channel 11 as the cavity, allow staff in oiling for the first time by first
Channel 31, which is connected in the cavity to be formed to first bearing chamber 22 with second bearing chamber, injects lubricant grease, and the air in cavity can be with
Cavity is discharged by second channel 11, avoids air and compress in the cavities and form high pressure, prevents grease from full of cavity, influence
Lubricant effect.In follow-up maintenance, cavity can not be dismantled, lubricating oil is still injected from first passage 31 by oil injection structure 32
Rouge, new grease flow to second bearing chamber from first bearing chamber 22 under the effect of the pressure and successively fill up in first bearing chamber 22
Gap in gap and second bearing chamber.Correspondingly, waste oil can be extruded cavity from second channel 11 by new grease, on
The complexity that operation simplifies attended operation is stated, the working efficiency of replacement grease is substantially increased.Simultaneously as replacement grease
Process do not need to tear open machine, staff, which can according to need, improves maintenance frequency, guarantees screw compressor working effect.
Specifically, as shown in Fig. 2, first crankshaft 50 of the present embodiment includes first rotating shaft 51, the second shaft 52 and connection
Structure 53, connection structure 53 are arranged between first rotating shaft 51 and the second shaft 52.First axle is provided in first bearing chamber 22
61 are held, first rotating shaft 51 is threaded through in first bearing 61, and second bearing is intracavitary to be provided with second bearing 62, and the second shaft 52 is worn
In second bearing 62, connection structure 53 is threaded through in separation structure 40.The company of being formed between connection structure 53 and separation structure 40
The communicating passage 64 of logical first bearing chamber 22 and second bearing chamber, first passage 31 are led to by the channel of first bearing 61 with being connected to
Road 64 is connected, and second channel 11 is connected by the channel of second bearing 62 with communicating passage 64.The channel of above-mentioned first bearing 61
The gap passed through in bearing arrangement for grease or hole, by taking roller bearing as an example, axis are referred to the channel of second bearing 62
There is certain interval, so that grease passes through between inner ring, outer ring and the roller held.
In the technical scheme of this embodiment, it is also detachably provided with end cap 91 on bracket 10, pacified when end cap 91 is fixed
When filling over the mount 10, end cap 91 can cover second channel 11, and second bearing chamber is made to form closed cavity.It is unloaded in oiling
For lower cover 91 to expose second channel 11, new lubricant grease injects first bearing chamber from oil injection structure 32 under the effect of the pressure
22, and flowed through first bearing chamber 22 to second bearing chamber, full of in the gap and second bearing chamber in first bearing chamber 22
Gap, grease old at this time can be discharged under the action of the pressure of new grease from second channel 11；After the completion of oiling, dress
Upper end cover 91 is to block second channel 11, and oil injection structure 32 can play the role of check valve at this time, makes lubricant grease will not be from
First passage 31 flows out first bearing chamber 22.
As shown in Figure 1, the screw compressor of the present embodiment further includes the second crankshaft 70, the second crankshaft is threaded through drive disk 20
Central through hole in drive drive disk 20 and orbiter 30 mobile.
