Description
Technical field
The present invention relates to the technical field of single screw compressor, a kind of specifically single screw compressor spider piece.
Background technology
Single screw compressor forms Meshing Pair by a cylindrical screw and two spider pieces being arranged symmetrically, mounted in casing
It is interior.Screw channel, casing inner wall and spider piece form enclosed volume.Power is passed on screw shaft, and star-wheel rotation is driven by screw rod.
Gas is entered in screw channel by suction muffler, is discharged after compression by vent ports and discharge chamber.Functioning as star-wheel is reciprocal
The piston of piston compressor, when spider piece relative motion in screw channel, enclosed volume is gradually reduced, and gas is compressed, star
The problems such as tooth of wheel piece is oily because lubricating oil is easily run and is lost so that spider piece considerable wear, therefore the abrasion of spider piece
Problem turns into the bottleneck of the current most critical of single screw compressor.
The content of the invention
The technical problems to be solved by the invention are：A kind of single screw compressor spider piece is provided, it is in compressor operating
During can make lubricating oil equably, continually form between gear piece and compressor case inner chamber, between gear piece and screw rod, from
And the abrasion of gear piece is reduced, and reduce loss of lubrication.
The technical solution used in the present invention is：A kind of single screw compressor spider piece is provided, if it include a rotor and
Dry gear piece, some longitudinal flutings is provided with the rotor, the gear piece is installed in the longitudinal fluting, the surface of gear piece one
On it is neat with upper, the left and right periphery of the gear piece respectively at least provided with two interlaced reinforcements, the reinforcement both ends
Flat, the reinforcement intersection is provided with circular counter bore, and groove is provided with the reinforcement, and the groove communicates with circular counter bore,
The gear piece crown center is provided with pit, and the groove communicates with pit.
The gear piece being installed on the rotor is detachable, is convenient for changing and cleaning gear piece.
The reinforcement both ends are round-corner transition with the periphery place of flushing of the gear piece respectively, the groove on the reinforcement
The periphery place of flushing with the gear piece is chamfered transition, facilitates lubricating oil to flow into gear piece peripheric surface.
The groove cross section is rectangle, semicircle or triangle, and lubricating oil can flow along in groove.
The pit cross section is rectangle, semicircle or triangle, and the lubricating oil injected outside compressor is collected simultaneously
Storage.
After above structure, a kind of single screw compressor spider piece of the invention has following excellent compared with prior art
Point：Interlaced reinforcement adds gear piece intensity on gear piece, can avoid gear piece under air high pressure or with outside compressor
Flexural deformation in shell inwall and screw rod friction, and extend the service life of gear piece；Circular counter bore as confluence in grease,
Both lubricating oil can be stored, the lubricating oil of storage can be supplied to the groove that each bar communicates therewith again；Connect at the top of gear piece with screw rod
Touch, therefore the screw rod that the lubricating oil in pit is rotated is taken away and lubricates screw rod and gear piece, in addition, the pit at the top of gear piece will press
The lubricating oil of injection is collected and stored outside contracting machine, reduces the waste of lubricating oil.

Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
The present invention provides a kind of single screw compressor spider piece, and the both sides of a screw rod 14 respectively set a spider piece in symmetry,
It includes a rotor 1 and some gear pieces 2 to one planetary gear, and rotor 1 is installed on prime mover in cylinder 8, is provided with rotor 1 some
Longitudinal fluting 3, because the surface of gear piece 2 one is provided with the reinforcement 4 of more than two, the inwall of longitudinal fluting 3 one side is provided with to match therewith
The spill guide rail of conjunction, so gear piece 2 can be installed in longitudinal fluting 3.As shown in figure 1, the surface of gear piece 2 one is provided with four straight lines
Type reinforcement 4, first perpendicular to pit 7, and one end is arrived at the minimum point of pit 7 and flushed with pit 7, flushes place's round-corner transition；
Article 2 perpendicular to first, both ends arrive at respectively the both sides of gear piece 2 and with both sides end face, flush place's round-corner transition；Separately
Outer two are symmetrically located at first both sides of reinforcement 4 centered on first respectively, both ends respectively with the end face of gear piece 2,
Flush place's round-corner transition, four reinforcements 4 the distribution of rice font；Three reinforcement 4 one is connected with pit 7, and other end connects
To the bottom of gear piece 2；The midpoint of four reinforcements 4 is intersecting to be converged at circular counter bore 5, pit 7 of the reinforcement 4 at the top of gear piece 2
Section is provided with groove 6, groove 6 and the end face of gear piece 2 between circular counter bore 5, flushes place's chamfered transition, groove 6 sinks with circle
Hole 5 and pit 7 communicate, and circular counter bore 5 is located at the center of gear piece 3 and close to the position of pit 7, when lubricating oil is from the oil outside compressor
Entrance 10 is injected, as shown in Fig. 2 oil-in 10 is located at the top of cylinder 8, lubricating oil is dropped to the pit 7 of gear piece 2 and tooth by Action of Gravity Field
The top of piece 2, prime mover rotor driven 1 rotate, and rotor 1 drives gear piece 2 to rotate, two planetary gear opposite direction rotatings, drive screw rod 14
Rotation, air are inhaled into from air intake 12, and the friction air of gear piece 2 produces heat, and lubricating oil is heated and by Action of Gravity Field, gear piece
A part of lubricating oil is left between 2 top and the inwall of compressor block 9 and forms one layer of oil film, a part of lubricating oil is in gear piece 2
Top and the contact position of screw rod 14 are taken away to form oil film by screw rod 14, and another part lubricating oil is flow to by the groove 6 on reinforcement 4
