Fluid-power motor the utility model being provided below in conjunction with accompanying drawing is described in detail.It should be noted that, mentioned various mode of executions in embodiment part herein, are only to understand the technical solution of the utility model for the ease of those skilled in the art, are not limited to protection domain of the present utility model.
The first mode of execution
The first mode of execution of the present utility model provides a kind of fluid-power motor.Please refer to Fig. 1, Fig. 1 is the schematic diagram of the fluid-power motor of the first mode of execution of the present utility model.In Fig. 1, upper half part is sectional view, and lower half portion is front view.As shown in Figure 1, in the first mode of execution, the support 2 that described fluid-power motor comprises cylindrical shell 1 and rotates for supporting cylindrical shell 1, inwall at cylindrical shell 1 self longitudinally offers one or more spiral through hole 101, and spiral through hole 101 extends to the second end face 103 (as the right side of Fig. 1) from first end face 102 (as the left side of Fig. 1) of cylindrical shell 1.Described spiral through hole 101 has the first opening 1011 and the second opening 1012, and described the first opening 1011 is on the first end face 102 of described cylindrical shell 1, and described the second opening 1012 is on the second end face 103 of described cylindrical shell 1012.Described cylinder material is preferably stainless steel, also can use engineering plastics etc., as long as do not fractureed can meet rotation time.
On the inwall of described cylindrical shell 1 self, one or more spiral through hole 101 is set, and make described spiral through hole 101 extend to described the second end face 103 from the first end face 102 of described cylindrical shell, can in described spiral through hole 101, pass into for example high pressure water of highly pressurised liquid or high pressure slurry 3 (as shown by arrows in FIG., can be understood as highly pressurised liquid or high pressure slurry), as mentioned above, one is thought, this highly pressurised liquid or high pressure slurry 3 act on the hole wall of described spiral through hole 101, produce pressure, promoting described cylindrical shell 1 rotates with respect to described support 2.Because described highly pressurised liquid or high pressure slurry 3 flow along the spiral through hole 101 of described cylindrical shell 1 inside, therefore can not cause due to the gap between described cylindrical shell 1 and described support 2 loss of highly pressurised liquid or high pressure slurry 3, and due to underfill highly pressurised liquid or high pressure slurry 3 between described cylindrical shell 1 and described support 2, therefore can between described cylindrical shell 1 and described support 2, fill other media as oiling agent etc. or such as bearing of other mechanisms etc. is set, this is alleviated the friction between described cylindrical shell 1 and described support 2 on the one hand, make on the other hand described cylindrical shell 1 relative loose with the cooperation of described support 2, not only reduce the requirement on machining accuracy of the two, and be not easy to occur described cylindrical shell 1 and the stuck phenomenon of described support 2.In the first mode of execution, between described cylindrical shell 1 and described support 2, bearing is set, will specifically discuss hereinafter about this bearing.
Particularly, highly pressurised liquid or high pressure slurry 3 (water or mud) can enter spiral through hole 101 from the first end face 102 shown in Fig. 1 (being left side shown in Fig. 1), and spray from the second end face 103 (being right side shown in Fig. 1), thereby drive cylindrical shell 1 to rotate, now the common fluid-power motor that forms of cylindrical shell 1 and support 2.If the front end at cylindrical shell 1 is connected in drill bit 5 by bindiny mechanisms such as socket head screws 4, just can become the fluid power being driven by highly pressurised liquid or high pressure slurry 3 bores, in the municipal engineering of oil, colliery, metallurgy and non-excavation, can be widely used in horizontal drilling, vertically creep into, inclined boring etc.In the utility model, high pressure water, the fluids such as high-pressure slurry, can serve as power source.It should be noted that, support 2 is mainly support force for the active force of cylindrical shell 1, rather than frictional force, in other words, for cylindrical shell 1 of the present utility model is rotated, wish to reduce the frictional force between support 2 and cylindrical shell 1, ideal mode is that the frictional force between support 2 and cylindrical shell 1 is zero.Because the frictional force between support 2 and cylindrical shell 1 is less, it is also just less that cylindrical shell 1 rotates suffered resistance.
Please refer to Fig. 2 and Fig. 4, Fig. 2 is the structure perspective view of the cylindrical shell of the fluid-power motor of the first mode of execution shown in Fig. 1, and Fig. 4 is the sectional drawing of the cylindrical shell of the fluid-power motor of the first mode of execution shown in Fig. 1.As shown in the figure, spiral through hole 101 in above-mentioned the first mode of execution is set to the outer surface near cylindrical shell 1, far away apart from the central axis of cylindrical shell 1, like this in the time that highly pressurised liquid or high pressure slurry 3 promote cylindrical shell 1 around its central axis rotation, larger with respect to the torque of the central axis of this cylindrical shell 1.For example, the edge 1013 of spiral through hole 101 is, below 5mm, to be preferably below 4mm from the distance H of the outer surface 104 of cylindrical shell 1.In the utility model, the edge of described spiral through hole refers to, from the nearest edge of the outer surface of cylindrical shell.As shown in Figure 5, draw the center of circle that straight line BB crosses the center of circle of cylindrical shell 1 and passed spiral through hole 101 simultaneously, now, the intersection point of straight line BB and spiral through hole 101 just can be thought a some a on the edge 1013 of spiral through hole 101, the intersection point of the outmost turns of straight line BB and cylindrical shell 1 can be thought a some b on outer surface 104, and the distance between some a and some b is distance H recited above.
In above-mentioned the first mode of execution, mention, on the inwall of cylindrical shell 1 self, longitudinally offer multiple spiral through holes 101, particularly the plurality of spiral through hole 101 is preferably parallel spiral through hole.Be arranged in parallel and make each spiral through hole 101 be subject to producing equidirectional component after high-pressure liquid promotion, thereby guarantee the maximum of making a concerted effort that forces cylindrical shell 1 to rotate.When have multiple spiral through hole on the inwall of cylindrical shell self time, the plurality of spiral through hole can be also uneven spiral through hole.As long as above-mentioned multiple spiral through hole 101 is for being distributed in fifty-fifty on the inwall of cylindrical shell 1 self, the each several part that can make cylindrical shell 1 be separated by spiral through hole 101 is stressed evenly, thereby cylindrical shell 1 can be to rotate relative to state stably.For example, as shown in Figure 3 and Figure 5, Fig. 3 is the A-A sectional view of Fig. 2, Fig. 5 is that the A-A of the cylindrical shell of the fluid-power motor of the first mode of execution shown in Fig. 2 is to sectional view, in the fluid-power motor of the first mode of execution, be on average provided with 4 spiral through holes 101, the spiral through holes of even number such as 2,6,8,10,12 also can be on average set, or the spiral through holes of odd number such as 1,3,5,7,9 are set fifty-fifty.In the utility model, the number of spiral through hole is restriction not, promotes cylindrical shell rotation as long as can realize.
In above-mentioned the first mode of execution, mention, on the inwall of cylindrical shell 1 self, longitudinally offer multiple spiral through holes 101,, in the inner-wall material of cylindrical shell 1 self, longitudinally offer multiple spiral through holes 101, for example stainless steel of material that the edge of said through hole is configured cylindrical shell surrounds.
Please refer again to Fig. 1, rotate in order to support cylindrical shell 1, support 2 has axle 201, at least a portion of this axle is positioned at the inner chamber of cylindrical shell 1, thereby cylindrical shell 1 can be rotated around this axle 201, and in the first mode of execution, most axle 201 is all positioned at the inner chamber of cylindrical shell 1.This axle 201 supports cylindrical shell 1 rotation except playing carrier function, the effect of hand-held this motor of person that also plays easy-to-operat.Between described axle 201 and cylindrical shell 1, have bearing 6, the relative rotation between axle 201 and cylindrical shell 1 will be more convenient like this.In the present embodiment, needle bearing can be selected, because needle bearing radial thickness is less, the overall dimension of fluid-power motor can be reduced.Can certainly select other bearings such as roller bearing or ball bearing.In addition, consider from realizing the counterrotating angle of cylindrical shell 1 and support 2, also can not use bearing and oiling agent, such as lubricant oil or water etc. are set between axle 201 and cylindrical shell 1.
Preferably, in the first mode of execution, between described axle 201 and cylindrical shell 1, there are multiple bearings 6, most preferably be at the two ends of axle 201 bearing 6 is respectively set.In some cases, if the length of axle is larger, occur bending and deformation for fear of axle so, a bearing also can be set at the middle part of axle again, to be used as supplemental support.
As shown in Figure 1, when this fluid-power motor is connected with drill bit 5 and with high pressure water during as driving fluid, can connect drill bit 5 at the right-hand member of cylindrical shell 1, now can also on the first end face 102 of cylindrical shell 1, end cover 7 be set to seal the left end of spiral through hole 101, avoid high pressure water to reveal from the first end face 102 of cylindrical shell 1.Installing after end cover 7, in order to input continuously high pressure water in spiral through hole 101, axle 201 can be stretched out to end cover 7 one segment length, and along it, blind hole 2011 (left section of this axle is hollow shaft) is axially set in axle 201, in cylindrical shell 1, be provided with the cavity 8 communicating with this blind hole 2011, this cavity 8 is communicated with mutually with each spiral through hole 101.Like this, can only in this blind hole 2011, pass into high pressure water, and then by this blind hole 2011, high pressure water be introduced to cavity 8_ and then introduced each spiral through hole 101.Thereby needn't pass into high pressure water to multiple spiral through holes 101 simultaneously.In Fig. 1, the flow direction of high pressure water is shown with arrow.
In the first mode of execution, described fluid-power motor also comprises highly pressurised liquid supplier or high pressure slurry supplier (not shown), described highly pressurised liquid supplier is communicated with described spiral through hole 101, can be communicated with the first opening 1011 of described spiral through hole 101 particularly, thereby supply with the fluid such as highly pressurised liquid or high pressure slurry for this spiral through hole 101.In actual use, described highly pressurised liquid supplier or high pressure slurry supplier can be communicated with spiral through hole 101 indirectly.For example, in the first mode of execution, first this highly pressurised liquid supplier or high pressure slurry supplier are communicated with the blind hole 2011 in axle 201, then by the cavity 8 arranging in cylindrical shell 1, finally realize and being communicated with spiral through hole 101.As highly pressurised liquid supplier or high pressure slurry supplier, those skilled in the art can be as required, use any type of highly pressurised liquid supplier or high pressure slurry supplier in prior art, for example high pressure water supplier or high-pressure slurry supplier.
