Abstract
The utility model discloses a kind of bent axle of piston compressor and piston compressor, bent axle includes：Eccentric part, the oil outlet of the eccentric part roof, tangential direction extension of the oil outlet along the eccentric part are formed through on the eccentric part.By setting above-mentioned oil outlet, the fuel-displaced resistance of bent axle can be reduced, and the lubricity between each part can be increased, and the Energy Efficiency Ratio for entering power, piston compressor being improved of compressor can also be reduced.
Description
Technical field
It the utility model is related to Compressor Technology field, more particularly to the bent axle of a kind of piston compressor and with should
The piston compressor of bent axle.
Background technology
In operation process, motor driven bent axle rotates compressor together, and bent axle is by oil pump component from compressor housing
Interior suck lubrication oil, lubricating oil is via the oilhole on bent axle and each part of oil-bath lubrication.But the oil outlet one in crankshaft eccentric portion
As it is axially disposed, so fuel-displaced difficulty is big, and the effect of lubrication connecting rod, the piston pin that is connected with connecting rod and piston is poor, and
And compressor enters that power is larger, the efficiency of compressor is poor.
Utility model content
The utility model is intended to one of technical problem at least solving in correlation technique to a certain extent.Therefore, this reality
With a kind of bent axle of piston compressor of new proposition, the bent axle can reduce fuel-displaced resistance, can improve oil lubrication company
The effect of bar, the piston pin being connected with connecting rod and piston.
The utility model further proposes a kind of piston compressor.
According to the bent axle of piston compressor of the present utility model, including：Eccentric part, it is formed through on the eccentric part
The oil outlet of the eccentric part roof, tangential direction extension of the oil outlet along the eccentric part.
According to bent axle of the present utility model, the fuel-displaced resistance of bent axle can be reduced, and can be increased between each part
Lubricity, and the Energy Efficiency Ratio for entering power, piston compressor being improved of compressor can also be reduced.
In addition, following distinguishing feature can also be had according to the bent axle of piston compressor of the present utility model：
In some examples of the present utility model, formed with going out oil groove in the side wall of the eccentric part, it is described go out oil groove not
Through the eccentric part roof, it is described go out oil groove be connected with the oil outlet.
In some examples of the present utility model, it is described go out oil groove be configured to prolong along the axially inclined of the eccentric part
Stretch.
In some examples of the present utility model, the oil outlet is circular port, slotted eye, Long Circle hole or polygon
Hole.
According to piston compressor of the present utility model, include the bent axle of described piston compressor.
The beneficial effect of the piston compressor is identical with the beneficial effect of the bent axle, will not be described in detail herein.
Brief description of the drawings
Fig. 1 is the sectional view according to the eccentric part of the bent axle of the utility model embodiment.
Reference：
Eccentric part 10；Oil outlet 11；Go out oil groove 12.
Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings.Below by
The embodiment being described with reference to the drawings is exemplary, it is intended to for explaining the utility model, and it is not intended that new to this practicality
The limitation of type.
Below with reference to the accompanying drawings the bent axle according to the utility model embodiment is described in detail, the bent axle can be applied in piston type
In compressor.
As shown in figure 1, it can be included according to the bent axle of the utility model embodiment：Eccentric part 10, formed on eccentric part 10
There are the oil outlet 11 through the roof of eccentric part 10, tangential direction extension of the oil outlet 11 along eccentric part 10.It is understood that edge
The oil outlet 11 of the tangential direction extension of eccentric part 10 can cause lubricating oil to have along perpendicular to the radial direction of eccentric part 10
It speed, can so be flowed out in order to lubricating oil out of oil outlet 11, and connecting rod can be preferably lubricated in order to lubricating oil, with connecting
Bar connected piston pin and piston.
Thus, according to the bent axle of the utility model embodiment, the fuel-displaced resistance of bent axle can be reduced, and can be increased each
Lubricity between part, and the Energy Efficiency Ratio for entering power, piston compressor being improved of compressor can also be reduced.
Wherein, formed with oil groove 12 is gone out in the side wall of eccentric part 10, go out oil groove 12 not through the roof of eccentric part 10, go out oil groove
12 are connected with oil outlet 11.Wherein, the lubricating oil for flowing through out oil groove 12 can have tangential velocity, so can preferably just
It is fuel-displaced in oil outlet 11, and the lubricating oil for flowing through out oil groove 12 can lubricate the contact surface between eccentric part 10 and connecting rod, can
To cause eccentric part 10 and connecting rod reliable operation, matching relationship stabilization.
Preferably, axially inclined extension along eccentric part 10 can be configured to by going out oil groove 12.So going out oil groove 12 can be with
The contact surface between eccentric part 10 and connecting rod is preferably lubricated on the axial direction of eccentric part 10, the He of eccentric part 10 can be improved
The cooperation reliability of connecting rod.
Alternatively, oil outlet 11 can be circular port, slotted eye, Long Circle hole or polygonal hole.
According to the bent axle of the piston compressor of the utility model embodiment, including above-described embodiment.
In the description of this specification, reference term " one embodiment ", " some embodiments ", " example ", " specifically show
The description of example " or " some examples " etc. means specific features, structure, material or the spy for combining the embodiment or example description
Point is contained at least one embodiment or example of the present utility model.In this manual, to the schematic table of above-mentioned term
State and be necessarily directed to identical embodiment or example.Moreover, specific features, structure, material or the feature of description can be with
Combined in an appropriate manner in any one or more embodiments or example.In addition, in the case of not conflicting, this area
Technical staff the different embodiments or example and the feature of different embodiments or example described in this specification can be entered
Row combines and combination.
Although embodiment of the present utility model has been shown and described above, it is to be understood that above-described embodiment is
Exemplary, it is impossible to it is interpreted as to limitation of the present utility model, one of ordinary skill in the art is in the scope of the utility model
