Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.
On the one hand the utility model provides a kind of oiling blade, the oiling blade include spire 1 and with the spiral
The connected folded edges 2 in the one end in portion 1, the folded edges 2 include the main body of plane or curve form and from the main bodys
Relative both sides be respectively facing the flanging 21 of the center line bending of the spire 1 for gear oil.
In the above-mentioned technical solutions, as shown in figure 1, oiling blade one end connection flanging structure 2 of spire 1, it is described
Folded edges 2 include the main body of plane or curve form and are respectively facing the spire from the relative both sides of the main body
Center line bending for the flanging 21 of gear oil, be the function that gear oil can be achieved by flanging 21, and using oil pump case
Oil pumping system is compared, and number of parts is less, simple in construction and easy to assembly, so as to reduce cost and be advantageous to production efficiency
Improve.
Wherein, in order to ensure the degree of balance of oiling blade and oil effect, it is preferable that the flanging 21 is on the center
Line Central Symmetry.
Also, the shape of flanging 21 has multiple choices.As shown in Figures 3 to 6, it is preferable that the flanging 21 is rolled over for plane
One of side, arc flanging and waveform flanging.Wherein, flanging 21 is mainly to substitute oil pump case to realize the work(of gear oil
Energy.
It should be noted that considering from formability and the convenience of processing, the main body of flat shape can be easy to be molded spire 1
When clamping and fixed oiling blade, meanwhile, also allow for machine-shaping flanging 21, and although the main body of curve form adds processing
Difficulty, but the effect to oil can be better ensured that.
Preferably, the main body is flat shape：As shown in figure 3, the flanging 21 is plane flanging, the plane flanging
Angle between the main body is θ, 10 °≤θ≤80 °；The flanging 21 is arc flanging, and the arc length of the arc flanging is
L1, the width of the main body are L2, and the both ends of 0 ＜ L1/L2≤1.5 or the arc flanging are relative with the main body respectively
Both sides connect.Because for plane flanging form, oily effect is preferably kept off in order to ensure to realize, the angle of flanging 21 should be use up
Amount is not more than 90 °.And for arc flanging, as shown in Figure 4 and Figure 5, when two arc flangings can realize preferable closed form
During state, it is assumed that the angle of circumference of circular arc is that α, flanging arc length L1 and the width L2 of main body (non-tuck portion) have following relation, L1/L2
=α/sin α；From functional relation, when 0≤α≤pi/2, function f (α)=α/sin α monotonic increases, in α=pi/2, letter
Number acquirement maximum, about 1.5；When closure is not implemented in tuck portion, it is only necessary to L1/L2 ＞ 0, therefore 0 ＜ L1/L2≤
1.5.Certainly, as shown in figure 5, the both ends of arc flanging also can be respectively with the main body relative both sides be connected, so as to be formed
Arc closes flanging.
As shown in Figure 2, it is preferable that length of the folded edges 2 along the centerline direction is H, 12mm≤H≤
30mm.It can so ensure that the length that oiling blade exposes the crankshaft end-face part being explained below is 12-22mm, this length can
So that oiling blade tuck portion is combined closely with crankshaft end-face part, it is contemplated that in present oil supply structure, under some bent axles
End face can be deep under pasta, use oil mass to reduce, pasta is suitably reduced, in order to ensure to contact with pasta, so plus
The length range of main body is grown.
Preferably, the oiling blade includes the planar portions 3 being connected with the other end of the spire 1.The master of planar portions 3
It is fixed oiling blade to act on, and can be the shape of plane therefore without realizing the function of pump oil.On furthermore, it is contemplated that
Oily blade will use the connected mode of interference fit with the bent axle being explained below, and install for convenience, it is preferable that the plane
The breach 31 for being used to install along centerline direction extension is provided with portion 3.Wherein, unsuitable excessive, the mistake of the size of breach 31
The big intensity decreases for easily causing planar portions 3, the failure risk that increase oiling blade is connected with bent axle, but the size of breach 31 are not yet
Should be too small, it can so increase installation difficulty.For example, the width of breach 31 can be 1mm.
The utility model second aspect provides a kind of compressor, and the compressor includes electric machine assembly, passed with the motor
The bent axle and above-mentioned oiling blade, the bent axle of dynamic connection are provided with centre bore, and the oiling blade is arranged on the center
In hole.Because the compressor includes above-mentioned oiling blade, therefore the oily function of gear can be achieved by flanging 21, and using oil pump
The oil pumping system of housing is compared, and number of parts is less, simple in construction and easy to assembly, so as to reduce cost and be advantageous to produce
The raising of efficiency.
Wherein it is preferred to the spire 1 is interference fitted with the centre bore.It is further preferred that the folded edges
2 are inserted partially into the centre bore and are interference fitted with the centre bore；And/or the oiling blade includes and the spiral
The connected planar portions 3 of the other end in portion 1, and the planar portions 3 are interference fitted with the centre bore.Oiling blade is used into interference
The mode of cooperation is arranged on bent axle, and the installation site of oiling blade can be made relatively reliable, improve the safety in utilization of device
Energy.
Preferred embodiment of the present utility model, still, the utility model and unlimited is described in detail above in association with accompanying drawing
In this.In range of the technology design of the present utility model, a variety of simple variants can be carried out to the technical solution of the utility model,
It is combined in any suitable manner including each particular technique feature.In order to avoid unnecessary repetition, the utility model
Various combinations of possible ways are no longer separately illustrated.But these simple variants and combination should equally be considered as the utility model institute
Disclosure, belong to the scope of protection of the utility model.
