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 technique
Single screw compressor forms Meshing Pair by a cylindrical screw and two spider pieces being arranged symmetrically, and is mounted in casing
It is interior.Screw channel, casing inner wall and spider piece constitute enclosed volume.Power passes on screw shaft, drives star-wheel rotation by screw rod.
Gas is entered in screw channel by suction chamber, 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 tooth of piece is taken turns because lubricating oil is easy the problems such as running oil and loss, so that spider piece considerable wear, therefore the abrasion of spider piece
Problem becomes the bottleneck of the current most critical of single screw compressor.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of single screw compressor spider piece, run in compressor
Can make in the process lubricating oil equably, continually form between gear piece and compressor case inner cavity, 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: provide a kind of single screw compressor spider piece, if it include a rotor and
Dry gear piece is provided with several longitudinal grooves on the rotor, and the gear piece is installed in the longitudinal groove, one surface of gear piece
On at least provided with two interlaced reinforcing ribs, the reinforcing rib both ends are neat with upper, the left and right periphery of the gear piece respectively
Flat, the reinforcing rib intersection is equipped with circular counter bore, is provided with groove on the reinforcing rib, and the groove is communicated with circular counter bore,
The gear piece top center is provided with pit, and the groove is communicated with pit.
The gear piece being installed on the rotor is detachable, is convenient for changing and cleaning gear piece.
The reinforcing rib both ends are respectively round-corner transition with the periphery place of flushing of the gear piece, the groove on the reinforcing rib
It is chamfered transition with the periphery place of flushing of the gear piece, lubricating oil is facilitated to flow into gear piece peripheric surface.
The groove cross section is rectangle, semicircle or triangle, and lubricating oil can be along flowing in groove.
The pit cross section is rectangle, semicircle or triangle, and the lubricating oil injected outside compressor is collected simultaneously
Storage.
After using the above structure, a kind of single screw compressor spider piece of the invention has following excellent compared with prior art
Select: interlaced reinforcing rib increases gear piece intensity on gear piece, can to avoid gear piece under air high pressure or with outside compressor
Bending deformation in shell inner wall and screw rod friction, and extend the service life of gear piece；Circular counter bore as confluence in grease,
Not only it can store lubricating oil, but also the lubricating oil of storage can be supplied into the groove that each item communicates therewith；It is connect at the top of gear piece with screw rod
Touching, therefore screw rod and gear piece are taken away and lubricated to the screw rod that the lubricating oil in pit is rotated, in addition, the pit at the top of gear piece will press
The lubricating oil injected outside contracting machine is collected and stores, and reduces the waste of lubricating oil.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and specific embodiments.
The present invention provides a kind of single screw compressor spider piece, and 14 both sides of a screw rod respectively set a spider piece in symmetry,
It includes a rotor 1 and several gear pieces 2 to one planetary gear, and rotor 1 is installed on prime mover in cylinder 8, is provided on rotor 1 several
Longitudinal groove 3, because 2 one surface of gear piece is equipped with two or more reinforcing ribs 4,3 inner wall of longitudinal groove is equipped on one side to match therewith
The spill guide rail of conjunction, so gear piece 2 can be installed in longitudinal groove 3.As shown in Figure 1,2 one surface of gear piece is equipped with four straight lines
Type reinforcing rib 4, first perpendicular to pit 7, and one end is arrived at 7 minimum point of pit and is flushed with pit 7, and place's round-corner transition is flushed；
Article 2 perpendicular to first, arrive at the two sides of gear piece 2 respectively and flush with both sides of the face by both ends, flushes place's round-corner transition；Separately
Outer two respectively centered on first symmetrically be set to first 4 both sides of reinforcing rib, both ends respectively with 2 end face of gear piece,
Flush place's round-corner transition, four reinforcing ribs 4 the distribution of rice font；Three reinforcing rib 4 one are connected with pit 7, and other end connects
To 2 bottom of gear piece；The midpoint intersection of four reinforcing ribs 4 converges at circular counter bore 5, pit 7 of the reinforcing rib 4 at 2 top of gear piece
Section is provided with groove 6, groove 6 and 2 end face of gear piece between circular counter bore 5, flushes place's chamfered transition, and groove 6 and circle are heavy
Hole 5 and pit 7 communicate, and circular counter bore 5 is located at 3 center of gear piece and close to 7 position of pit, when lubricating oil is from the oil outside compressor
Entrance 10 injects, as shown in Fig. 2, oil-in 10 is located at 8 top of cylinder, lubricating oil is dropped to 2 pit 7 of gear piece and tooth by gravity
2 top of piece, prime mover drive rotor 1 to rotate, and rotor 1 drives gear piece 2 to rotate, two planetary gear opposite direction rotatings, drives screw rod 14
Rotation, air are inhaled into from air intake 12, and the friction air of gear piece 2 generates heat, and lubricating oil is heated and by gravity, gear piece
There are a part of lubricating oil to form one layer of oil film between 29 inner wall of top and compressor block, and a part of lubricating oil is in gear piece 2
Top and 14 contact position of screw rod are taken away to form oil film by screw rod 14, and another part lubricating oil is flow to by the groove 6 on reinforcing rib 4
Circular counter bore 5, since air pressure acts on 2 surface of gear piece equipped with reinforcing rib 4, air pressure is squeezed in circular counter bore 5
Lubricating oil, lubricating oil flow in pit 7 by groove 6, gravity and centrifugation of the lubricating oil in pit 7 when gear piece 2 rotates
Under power effect, it flow to one layer of oil film of formation between 9 inner wall of top and compressor block of gear piece 2, the lubricating oil in circular counter bore 5
Part flows into 2 both sides of the face of gear piece, to form one layer of oil film, pressure-air between 2 side of compressor head 11 and gear piece
Blown out along with lubricating oil from air outlet slit 13, when between the top of gear piece 2 and 9 inner wall of compressor block, 2 top of gear piece and screw rod
Oil film between 14, between 2 two sides of gear piece and compressor head 11 is gradually depleted that new lubricating oil is passed through from circular counter bore 5
It crosses groove 6 and is continuously replenished into and form new oil film.
Preferred embodiments of the present invention are described above, but are not to be construed as limiting the scope of the invention.This hair
