Specific embodiment
1. the structure of the adjustable oil bits seperator of velocity-reducing chamber
As shown in Figure 1, the adjustable oil bits seperator of velocity-reducing chamber is by shell, hollow cylinder (1), rotary pot (2) and motor (3)
Composition.Hollow cylinder (1) is covered in the outside of rotary pot (2), can be slided up and down and be locked along common symmetry axis, the two group ingredient
The rotary body disembarked, installation is inside the housing.Motor (3) be mounted on shell in the following, motor (3) and rotary pot (2) shaft phase
Connection.Rotary pot (2) and hollow cylinder (1) constitute smooth surface, to avoid high-speed motion metal fillings to hollow cylinder (1)
Inner wall damages.Hollow cylinder (1) upper end is provided with equally distributed oil outlet (4), oil outlet (4) below, rotary pot (2) with
On cylindrical cavity be known as velocity-reducing chamber.
2. oil bits are in the motion analysis of a rotating body
In actual use, with oil metal fillings be by the continuously row of feeding/into bits mouth (5), it is oily in this case
Bits separation function, which reaches ideal separating effect, means that it can also reach ideal separating effect to monolithic band oil metal fillings.Cause
This, oil bits might as well be carried out in the motion analysis of a rotating body for monolithic band oil metal fillings.As shown in Fig. 2, band in rotary pot (2)
The centrifugal force F that oily metal chip is subject to can be decomposed into the component F upward along rotary pot (2) inner curve bus tangential direction1,
And chip is to the normal pressure F of rotary pot (2)2, furthermore effect of the chip also by inertia force, gravity and frictional force, wherein being used to
Property power be chip from contact rotary pot (2) position to the path of current location by power integral.When chip reaches rotary pot
(2) when edge, since rotary pot (2) and hollow cylinder (1) constitute smooth surface, maintain at this time the power of chip movement vertically to
On.The quality of chip, v are indicated with m0Indicate speed vertically upward when chip reaches rotary pot (2) edge, x (t) indicates chip
The height risen after runing time t in velocity-reducing chamber, ω indicate that the revolving speed of the rotary body of seperator, r indicate half on the inside of velocity-reducing chamber
Diameter, μ indicate the friction factor on the inside of chip and velocity-reducing chamber, then the normal pressure that chip is subject to, i.e. centrifugation force are mr ω2, then
Have
I.e.
It enables?
Solution
Wherein c1For undetermined constant.Utilize y (0)=v0?
I.e.
Therefore
Both ends integrate
Wherein c2For undetermined constant.It is obtained using x (0)=0
I.e.
Therefore
Due toThere is unique zero point
Therefore by displacement function
The maximum vertical penetration of chip is
As can be seen that chip rises to t0Moment displacement reaches maximum value xmax, speed zero, chip no longer rises at this time,
But it will not decline, unless its suffered gravity is greater than stiction.
3. the influence that seperator parameter moves chip
Although the parameter of some oil bits seperators involved in above-mentioned is not easy to determine, relevant function representation formula is utilized
Still can be on qualitative description be carried out on how these parameters influence movement of the chip in velocity-reducing chamber, these descriptions are for seperator
Design and deceleration cavity length adjustment all have important directive function.
Firstly, it can be seen from (4) formula in the case where material or certain friction factor, the maximum vertical penetration of chip
Unrelated with its quality, i.e. the maximum vertical penetration of the chip of different quality is equal.This guarantees selected suitable decelerations
Cavity length, the chip of same material can be discharged from the row of seperator/into bits mouth (5).It can from (1) formula and (2) formula
Out, the chip of identical material, the rule risen be also it is identical, the changing rule of speed is also identical, therefore de-oiling journey
Degree is also balanced.
Influence chip maximum vertical penetration is rotational speed omega, velocity-reducing chamber inner radius r and the chip of seperator rotary body
With the friction factor μ on the inside of velocity-reducing chamber.The increase of ω, r or μ can all make xmaxReduce.To guarantee that chip can be smoothly discharged, subtract
Fast cavity length is necessarily less than chip maximum vertical penetration, therefore for the seperator of different parameters, means when increasing ω, r or μ
The reduction of deceleration cavity length.From here it can also be seen that the chip of unlike material, deceleration cavity length should select different sizes,
This has also fully demonstrated the length-adjustable superiority of velocity-reducing chamber.
Z=μ r ω is enabled in (3) formula2, then
Utilize inequality
KnowTherefore
It is the monotone decreasing function of Z, i.e. t0It is long-pending μ r ω2Monotone decreasing function.Therefore work as product μ r ω2When increase, chip reaches most
The time of big lifting height is reduced.Particularly, when μ increases, the time that chip reaches maximum vertical penetration is reduced, same explanation
The chip of unlike material, deceleration cavity length should select different sizes, embody the length-adjustable superiority of velocity-reducing chamber.
When the timing of ω, r and μ mono-, chip speed v vertically upward at rotary pot (2) edge0Only with the shape of rotary pot (2)
Shape is related.The v it can be seen from (3), (4) two formulas0Bigger, chip rise time and maximum vertical penetration are also bigger.Therefore must not
The shape that deliberately design rotary pot (2) can reach ideal oil bits separating effect by adjusting deceleration cavity length.
4. the design and adjusting of velocity-reducing chamber
According to the analysis of front, the characteristics of motion and maximum vertical penetration and rise time of the chip in velocity-reducing chamber with
Its quality is unrelated, therefore front is equally applicable to chip stream to the analysis of chip.In order to metal fillings is smoothly discharged, row/into bits
The distance at mouth (5) to rotary pot (2) edge is preferably equal to the maximum vertical penetration of chip, and numerical value passes through although can not calculate
Experiment is readily available.For the adjusting convenient for deceleration cavity length, should be fully considered when designing hollow cylinder (1) various possible
The maximum vertical penetration of metal fillings therefrom selects the maximum as the length of hollow cylinder (1).
Adjust row/into bits mouth (5) to rotary pot (2) edge distance be equal to chip maximum vertical penetration in the case where,
Oil outlet (4) from row/into bits mouth (5) with a distance from it is remoter, the speed of chip vertically upward is bigger, in the effect of oil outlet (4) de-oiling
Fruit is poorer, therefore, should reduce as far as possible oil outlet (4) upper limb to row/into bits mouth (5) distance.
In addition, in order to which the oil droplet after separation is discharged after entering oil outlet (4) unblockedly, the shape of oil outlet (4)
Shape must be consistent with the motion profile of oil droplet.According to above-mentioned design, when chip reaches oil outlet (4) speed that rises have been approached for
Zero, along with the effect of gravity, movement in the vertical direction can be ignored, and need to only consider movement in the horizontal direction.
Since centrifugal force when oil, which is considered to be worth doing, reaches oil outlet (4) is mr ω2, therefore the centrifugal acceleration of isolated oil droplet is r
ω2, centrifugal speed is r ω2T, centrifugation distance is when into oil outlet (4) t seconds
And the angle that hollow cylinder (1) turns at this time is ω t.
It can be seen that the rotational speed omega and hollow cylinder (1) half of a motion profile for the oil droplet separated and seperator motor (3)
Diameter r is related.The shape of oil outlet (4) can be thus designed after the revolving speed and hollow cylinder (1) radius of motor (3) determine.
It crosses oil droplet burble point and makees a plane as polar plane, pole is made even the intersection point of face and axial line, and polar axis takes pole
With the line of oil droplet burble point, rotating polar-coordinate system is established, to describe the motion profile of oil droplet.It is assumed that the revolving speed of motor (3)
Be 30 revolutions per seconds, r=30 (cm), hollow cylinder (1) with a thickness of 3 (cm), motion profile of the oil droplet in rotating polar-coordinate system is such as
Shown in Fig. 3.
When oil droplet radial motion 3cm, the angle that hollow cylinder (1) turns over is 25.7831 °.From figure 3, it can be seen that oil droplet
From into oil outlet (4) to leaving oil outlet (4), track is substantially straight line tangent on the inside of one and hollow cylinder (1),
Therefore oil outlet (4) can be designed along the tangential direction on the inside of hollow cylinder (1).
To any constant ω, due to polar curve
With polar curve
Indicate same curve, and the shape of curve is only related with hollow cylinder (1) radius r, and cylinder wall thickness is usually not
It crosses several centimeters, therefore the variation of ω will not influence the shape of oil outlet (4).
Although hollow cylinder (1) radius r can influence the shape of above-mentioned curve, the value of r is usually not too large, such as not
More than 100 centimetres, still oil outlet (4) can be designed along the tangential direction on the inside of hollow cylinder (1) in this case.
