Abstract
The utility mode discloses a bent axle, wherein an oil-hole is equipped throughout a long-line and shot-line of the bent axle and the oil-hole's centre is deflected to an axis of the long-line and short-line of the bent axle. The utility model has beneficial effectes of technology that an inertia distance of the bent axle's eccentric mass is counteracted with an eccentric inertia distance produced by the whole oil-hole's eccentricity after an eccentric design of the bent axle's oil-hole, thereby improving the whole unbalancedness, effectively reducing the upper and lower counterbalance's mass of a rotor, improving equilibrium state to increase a rotating radius of oil and correspondingly increase centrifugal pull of rotation, increasing oil pressure and flow speed, and improving the whole lubricating character.
Description
Technical field
The utility model relates to a kind of bent axle, especially relates to a kind of bent axle of compressor.
Background technique
Compressor arrangement design at present sees also Fig. 1, is with design of bent axle 1 center oilhole 2 centers and bent axle 1 major and minor axis dead in line, such design, though no problem, from the balance angle, equilibrium block carries out the balance of eccentric shaft eccentric mass about the rotor of the bigger quality of needs design; Need to design bigger oilhole 2 diameters in addition,, improve centrifugal action, thereby satisfy lubricated needs to increase the turning radius of oil.
Summary of the invention
The purpose of this utility model is to provide a kind of bent axle, making does not need to design bigger oilhole diameter, just can increase the turning radius of oil, improves centrifugal action, satisfy lubricated needs, and the rotor that does not need to design bigger quality up and down equilibrium block carry out the balance of eccentric shaft eccentric mass.
The technical solution of the utility model is: bent axle of the present utility model is provided with through the oilhole of bent axle length line, and this oilhole misalignment is in described bent axle major and minor axis axis.
Preferred version of the present utility model is: this bent axle diameter is big.
Preferred version of the present utility model is: this bent axle applies in the compressor.
Preferred version of the present utility model is: this compressor is a rotary compressor.
Preferred version of the present utility model is: this compressor is the compressor that can guarantee the wall thickness of oilhole misalignment behind described bent axle major and minor axis axis.
The beneficial effects of the utility model: bent axle of the present utility model is by after the design of oilhole off-centreization, the inertia of crankshaft eccentric mass fraction is apart from being offset by the eccentric eccentric inertia distance that produces of whole oilhole, so whole disequilibrium improves, can effectively reduce equilibrium block quality up and down, improve state of equilibrium; Owing to the off-centre design of oilhole, make the turning radius of oil obtain increasing in addition, the corresponding increase of rotary centrifugal force, oil pressure and flow velocity improve, and cause the increase of oily circulating load, and whole lubrication property is improved.
Description of drawings
Fig. 1 is the structural representation of existing a kind of bent axle;
Fig. 2 is a crankshaft structure schematic representation of the present utility model.
Embodiment
See also Fig. 2, be bent axle of the present utility model.Be provided with an oilhole 20 that runs through bent axle 10 major and minor axis in the bent axle 10, these oilhole 20 misalignments are in bent axle 10 major and minor axis axis.Can obviously find out from Fig. 2, after the 20 off-centreization designs of bent axle 10 oilholes, the inertia of bent axle 10 eccentric mass part is apart from being offset by the whole oilhole 20 eccentric eccentric inertia distances that produce, and so whole disequilibrium improves, can effectively reduce equilibrium block quality up and down, improve state of equilibrium.Owing to the off-centre design of oilhole 20, make the turning radius of oil obtain increasing in addition, the corresponding increase of rotary centrifugal force, oil pressure and flow velocity improve, and cause the increase of oily circulating load, and whole lubrication property is improved.
Bent axle 10 of the present utility model is suitable for the bent axle of various diameters, is particularly suitable for that diameter is big, adopts in the machine that can guarantee the wall thickness after oilhole 20 off-centre.
Bent axle 10 of the present utility model can apply in the various compressors, and this compressor comprises rotary compressor.
The above; it only is the preferable concrete true mode of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore protection domain of the present utility model should be as the criterion with the protection domain of claims.
