This (2) is connected to the fixed ring and connected to the fixed structure, and can also be indirectly transmitted through the conductive member. It is not necessary to measure the dedicated electrostatic capacitance generating portion, so that the structure of the bearing 200923334 - the device can be simplified, and the device can be reduced. Moreover, the average pre-preparation of the rotating shaft can be stabilized by only two rotating bearings. The rigidity of the rotating shaft can be monitored steadily.

In the accompanying plural illustration, the bearing skirt of the present invention will be described with reference to Figs. 1 to 5, which is in the housing! Use the moon to apply the form. In the first embodiment, the main shaft 2 is freely rotatable. The hiding A and 3B support the main shaft 2, so that when the shaft is set, the shaft 2 becomes the spindle device, and the main shaft of the working machine is mounted on the main body of the main machine 2, which is tightly fitted along the shaft 8 inner ring 3i and the inter-turn Between the inner ring: knife = set of multiple bearings 3 Α, 3 Β, spacer 5. The bearing 3A (offer) is a rotating bearing in which the outer ring intermediate body T is interposed between H and 3g on the inner eve, and the plurality of rotating shafts are interposed between the rotating shafts and the shafts.

The outer ring 3 of the bearing 3Α, 3β: the inner ring 3g of the outer ring and the inner middle of the casing: the opposite direction—the shoulder-to-shoulder ratio is sandwiched between the Jc—the outer ring spacer ^ is self-impacting , two outer rings # The outer ring spacers 5, the inner width, the width dimension H1 and the inner ring ==== the outer ring spacers are different, the figure is right on the right end of the 200923334 .f The spacer 6 is inaccurately ~7, because the outer ring spacer 5 should be preloaded on the nut bearing of the abutting member. The Pw5 member 4 has a difference in width dimension and is energized in the inner rings 3i, 3i of the two bearings 3A, 3B. The outer ring spacer 5 and the conductive member such as the case, the shaft 2 and the inner ring spacer 4f are electrically insulated from the outer ring 3g; 2 = a conductive member. It is known that the insulating member 8 is interposed between the axially contacting surfaces of the outer ring as shown in Fig. 3 as sandwiched between the pinching fitting faces of the casing 1. The re-arcing member 8, the axial contact surface of the outer ring 3g and the housing} is also formed by sandwiching the insulating member outer ring 3g and the outer ring spacer 5 insulating material, and does not pre- (, the edge member 8 The sheet-shaped surface, the end surface, and the shell are further: the insulating member 8 such as the edge coating layer may be placed on the outside and on the contact surface of the outer ring spacer 5. The contact surface layer § is further provided with an insulating coating layer ZC instead of the insulating coating layer zc of the insulating coating layer zc on the outer ring 3g and the shell layer ZC of the insulating coating layer zc At least one of the members of the edge member 8 is required to have a combination of the electrical insulation of the outer ring 3g and the "multi-ZC". Any form can be used in the guide member like this.

In Fig. 4 (A), the outer ring 3g and the rotating body = a schematic diagram showing k. The lower lubricating film 13, i.e., the oil film, is formed with a thickness Ιμηι on the outside and transmits the load through the net slip film 13 to move the load. The electrostatic capacitance between the two sides of the lubrication is also the same as that of the bearing 12, and the outer diameter of the bearing is the same. If the lubricating film 13 is regarded as a conductor, the capacitor 15 is formed. The same as the inside of the ^, the electrode, then it is equivalent to a capacitor, also 16 〇 也 也 % % % 与 与 与 与 与 与 与 与 与 与 与 与 与 与 与 与 与 与 与 与 与 与 转动 转动 转动 转动 转动 转动 转动 转动 转动 转动 转动 转动The connected electric ', f, as shown in Fig. 4 - (Β), forms two electric capacitors Ca, Cb equal to each other, ^ ^. Here, if the capacitances of the two capacitors 15, 16 are /2. Further, it is assumed that the capacitance of the ^^^ capacitors ^ and 16 of the axis ^ is the capacitance scale of the Ca capacitor, and the body of the body is n', if the circuit structure of the connection of the respective rotors T is connected, These capacitances having the same capacitance can be regarded as the capacitance of the coil 3i, and the static capacitance Ca from the outer ring 3g is measured. In the inner ring 3i, the inner ring 3i is in the inner ring 3i, and the inner and outer rings 3i, 3 are used to measure the electrostatic current of the above-mentioned path. The main reason for the stability of the external part such as the current contact of the current collecting ring is required.

At this time, the equivalent circuit of the two outer rings 3g is set as shown in Fig. 4 =, so that they are not electrically conductive to each other. At this time, the electrode of the axis determining mechanism 9 is L ί7 ' The circuit path is: capacitance measuring spindle 2 ~ other - side wheel bearing 3B: inner outer ring 3 _ rotating body Τ ~ inner ring 3i - electrode 12 of the valley measuring mechanism 9. In this real two moving body T - outer ring 3 Bu electrostatic electricity is equivalent to a special allowance, 2 rotating bearings 3 Α, 3 Β, not limited to "6". At this time, the number η of each is set to 6. The capacitance of only a few n capacitors is the same as & ^It T and the inner and outer rings 3i, 3g, then the two rotating bearings 3a, 3B overall 200923334 electrostatic capacitance c is c = nCa / 4 If the electrostatic capacitance is such as 疋, the average electrostatic capacitance Ca of the rotating body τ and the inner!/1 space can be obtained. The lubricating film interposed between them can be measured by a capacitance meter or the like. 1 Capacity measuring mechanism 9 The total electrostatic electrons measured by the mechanism 9 are equal to each other.

The outer ring of the measuring ring is connected by the electrode 12 of the side to be used as the fixed product / g of the bearing 3B, and the electrode 11 of the other side is connected as the fixed piece of the bearing 3A. It can be placed on the fixed side without using the components such as the current collecting ring or the brush 10 200923334 3i or the rotating body τ with a non-contact ring or a brush, etc., so that the inner ring 3^=3=, since the current collecting bearing 3 is not used 3 Β orbital net 3 p Wang non-contact type and can measure the electrostatic capacitance in the capacitor part: Therefore, the invention is simpler than the structure formed by the body, and the invention can reduce the profit. Life problem. Therefore, the shaft has no current collecting ring or electricity, and it is possible to use a two-speed rotating spindle in the rotation of the bearing. Because f can properly manage the axis of the spindle, and the desired rotation precision is right at 5 hp conductive member Μ χψ ^ 8, it can save on the outer ring outer diameter surface %g = 吏 for electrical insulation On the insulating member spacer, for example, spraying the surface, the inner peripheral surface of the casing 1, and the time and step of drying the outer ring, such as coating layer ZC, and then waiting for the insulating coating layer zc, b 3 Manufacturing steps.

When the power is obtained, the bearing 3B can be connected in parallel, and the electrostatic circuit/Fig. 8 does not. That is, the bearing 3A is coupled. In this equivalent circuit, the outer ring. ^Do not insulate with these bearings Μ, 兕, but in a conducting state. In this case, the outer ring spacer 5 is not provided with the capacitance A and 3B of the capacitance generating portion 6A, and the electrostatic capacitance between the static bodies is added. ^% inner and outer ring 3" 3g and rotation are repeated.

This is obtained - the angle of the side axis ^3B pre-^. In the bearing device of the second embodiment only in the form of a series connection with the bearing 3B, the ί ring spacer 5 does not need to be insulated, so that it is not necessary to provide an electrode for the housing 1 and the outer casing YgJ1, and therefore it is also necessary to The bearing electrode of the second side of the bearing electrode has a hole through which the wire has passed, so that the rigidity of the housing can be prevented from being formed, and since the electrode 12 can be turned over, it can be improved and concentrated. The static part of the load 12 200923334 is part of the capacitance generating part 6Α, so it can be connected to the low-cost αα# low manufacturing cost. In addition, it can also reach the disk] J > dual use. Therefore, the energy drop is shown in Fig. 9 as an example, in which 'I, the first one of the H's.
