Abstract
The utility model discloses a crankshaft used for a compressor, which comprises a long shaft, a short shaft, a balance arm and an oil line, wherein the long shaft and the short shaft are connected through the balance arm; an oilhole is formed in the outer surface of the short shaft; an oil throwing groove is formed in the side part of the oilhole. When a closed type refrigeration compressor operates, partial lubricating oil is thrown from the oil throwing groove with the rotational motion of the crankshaft, so that the oil supply efficiency of the crankshaft is improved, the lubricating oil thrown from the oil throwing groove is splashed and spouted to a piston so as to lubricate the piston and an air cylinder, the oil line is simplified, and the lubricating efficiency is improved.
Description
Affiliated technical field
What the wood model utility related to a kind of refrigeration compressor gets rid of the oil groove crankshaft structure, specifically a kind ofly is applicable to enclosed refrigeration compressor, plays the fuel delivery adjusting and get rid of the bent axle of oil lubrication effect.
Background technique
The bent axle agent structure of enclosed refrigeration compressor is comprised of major axis, minor axis, balance arm and oil circuit.During installation, the major axis of bent axle is placed in the crankshaft hole of compressor crankcase, when compressor operating band dynamic crankshaft rotates, the lubricant oil that is positioned at the compressor housing bottom will rely on the centrifugal force that rotatablely moves and produce, by the oil circuit of bent axle, reach the purpose of friction pair between lubricated bent axle, crankcase and crankshaft-and-connecting-rod from bottom to up.But the general unobstructed degree only circulated for oil of existing crankshaft oilway carries out structural design, does not take into full account the affect problem of the oil mass of lubricant oil in oil circuit on fuel feeding efficiency, fuel delivery efficiency directly affects the working efficiency of compressor.In addition, lubricant oil is after carrying by crankshaft oilway, then is delivered to piston through the connecting rod oil circuit, for lubricating between piston and cylinder.Because oil circuit is too complicated, cause the Lubricating Oil quantity not sufficient between piston and cylinder, cause undue wear.
Summary of the invention
Wood model utility technical problem to be solved is to propose a kind of compressor bent axle that can simplify oil circuit, improve lubricant oil fuel feeding efficiency and lubricating efficiency.
For solving the problems of the technologies described above, a kind of compressor of wood model utility comprises major axis, minor axis, balance arm and oil circuit with bent axle, described major axis is connected by described balance arm with minor axis, and the outer surface of described minor axis is provided with oilhole, and the sidepiece of described oilhole is provided with and gets rid of oil groove.
Above-mentioned a kind of compressor bent axle, the described oil groove that gets rid of is straight trough, and it invests the outer surface of described minor axis, and a described side of getting rid of oil groove is connected with described oilhole, and opposite side extends to the end face of described minor axis.
Above-mentioned a kind of compressor bent axle, describedly get rid of the outer surface that oil groove invests described minor axis, and a described side of getting rid of oil groove is connected with described oilhole, and opposite side extends to described balance arm.
The wood model utility is owing to having adopted above-mentioned technical pattern, when enclosed refrigeration compressor turns round, when the centrifugal force that lubricant oil relies on the crankshaft rotating motion to produce goes out by oil circuit and from bent axle minor axis oilhole effluent from bottom to up, can make parts of lubricating oil along with rotatablely moving of bent axle throws away from getting rid of oil groove, not only can improve the fuel feeding efficiency of bent axle, and be sputtered onto piston through getting rid of the lubricant oil that oilhole throws away, lubricated between piston and cylinder, simplify oil circuit, improved lubricating efficiency.
The accompanying drawing explanation
Fig. 1 is the structural representation of wooden model utility bent axle;
Fig. 2 is an exemplifying embodiment schematic diagram of wooden model utility bent axle.
Embodiment
As shown in Figure 1, wood model utility bent axle comprises major axis 1, minor axis 2, balance arm 3 and oil circuit 4, major axis 1 and minor axis 2 are by balance arm 3 be connected (balance arm 3 is for counterweight and be connected major axis 1 and minor axis 2), the spiral chute of oil circuit 4 detours on the outer surface of major axis 1, and the spiral fluted two end part are provided with respectively upper oil hole 5 and lower oilhole 6.Minor axis 2 outer surfaces also are provided with oilhole 7, and the sidepiece of oilhole 7 is provided with and gets rid of oil groove 8.Get rid of oil groove 8 for straight trough, invest the outer surface of minor axis 2, the one side is connected with oilhole 7, and opposite side extends to the end face of minor axis 2, and (variation as an alternative, this side also may extend to balance arm 3.Simultaneously, get rid of oil groove 8 and also can adopt the groove of other shape).
As shown in Figure 2, by wooden model utility crankshaft installed, when the compressor, major axis 1 is placed in the crankshaft hole 11 of crankcase 10, and minor axis 2 is connected with connecting rod 12, and the opposite side of connecting rod 12 is connected with piston 13, and piston 13 is placed in crankcase cylinder 14.When major axis 1 rotates in the crankshaft hole 11 of crankcase 10, the lubricant oil that is positioned at the closed compressor casing bottom relies on the centrifugal force that rotatablely moves and produce, from bottom to up by crankshaft oilway 4.Part lubricant oil is at the lower oilhole 6 of major axis 1 outer surface, upper oil hole 5, oil circuit spiral chute and through forming the oil circulation between the internal oil channel 9 of major axis 1, minor axis 2 and balance arm 3, is used to form the fricting movement between the crankshaft hole 11 of film lubrication major axis 1 and crankcase 10.The lubricant oil of another part shunting is via the oil circuit of major axis 1 and balance arm 3, and suction is to minor axis 2 places, then overflows from oilhole 7 sides of minor axis 2.The lubricant oil part of overflowing forms oil film between minor axis 2 and connecting rod 12, and another part is thrown away by the oil groove 8 that gets rid of of oilhole 7 sides.The lubricant oil thrown away, due to effect of inertia, splashes to piston 13, for the reciprocating friction between the cylinder 14 of lube pistons 13 and crankcase 10, moves.
