Summary of the invention

However, in the case of the wear sensor disclosed in Patent Document 1, it is difficult to improve a resolution of a wear measurement because the resolution of the wear measurement depends on the machining accuracy of the block.

Likewise, in the case of the wear sensor disclosed in Patent Document 2, it is difficult to improve the resolution of the wear measurement because a lamination failure occurs when a plurality of substrates are laminated.

Accordingly, it is an object of the present invention to provide a wear sensor, a wear sensor device, a bearing and a method for adjusting the bearing that can improve a resolution of a wear measurement.

In order to solve the above problems, a wear sensor according to a first aspect of the present invention has an insulating substrate, the wear progress direction of which coincides with a longitudinal direction thereof, and which has a front end surface formed on one side of the insulating substrate to be worn, a pair of side surfaces which are separated from each other in a transverse direction perpendicular to the longitudinal direction and are respectively in contact with the front end surface, and a wiring formation surface surrounded by the front end surface and the pair of side surfaces and extending in the longitudinal direction includes a wiring group including a A plurality of continuity check wirings and at least one grounding wiring which are formed on the wiring formation surface so as to extend in the direction of wear progress and which are at intervals in a direction from a first side surface surface of the insulating substrate are disposed to a second side surface thereof, and wear detection wiring that is formed on the wiring formation surface and connects distal ends of the plurality of continuity check wirings and a distal end of the grounding wirings disposed on the front end surface side, on. The distal ends of the plurality of continuity test wirings and the distal end of the grounding wiring are arranged so that each respective distal end from the first side surface to the second side surface is further away from the front end surface a rear end surface of the insulating substrate is arranged. The wear detection wiring includes a plurality of detection wiring parts which are respectively electrically connected to distal ends of two adjacent wirings in the plurality of continuity check wirings and the grounding wiring.

According to the present invention, the wear sensor has the wiring group that includes the plurality of continuity check wirings and at least one grounding wiring, which are formed on the wiring formation surface so as to extend in the direction of wear progress, and which are arranged at intervals in the direction from the first side surface of the insulating Substrate are disposed to the second side surface thereof, and the wear detection wiring that is formed on the wiring formation surface and connects the distal ends of the plurality of continuity check wirings and the distal end of the grounding wirings disposed on the front end surface side, wherein the distal ends of the plurality of continuity test wirings and the distal end of the grounding wiring are arranged so that each respective distal end is far from the first side surface to the second side surface it is disposed away from the front end surface to a rear end surface of the insulating substrate, the wear detection wiring comprises a plurality of detection wiring parts each electrically connected to distal ends of two adjacent wirings in the plurality of continuity check wirings and the grounding wiring, and accordingly it is it is not necessary to form a gap for electrical insulation between the detection wiring parts in the wear progress direction.

Since a distance in the longitudinal direction of the insulating substrate can be reduced from a position where a detection wiring part is removed due to wear to a position where the next detection wiring part is removed, the resolution of wear measurement can be improved.

Since portions of the detection wiring parts that are adjacent to each other can be arranged so as to overlap in the wear advancing direction, the resolution of wear measurement can be made smaller than a width of the detection wiring part.

In the wear sensor according to the first aspect of the present invention described above, the plurality of detection wiring parts may each extend in a direction perpendicular to the wear advancing direction, and the wear detection wiring may have a stepped shape.

As described above, since the shape of the wear detection wiring is formed in a stepped shape with the plurality of detection wiring parts each extending in a perpendicular direction to the wear advancing direction, a timing at which each of the detection wiring parts is completely removed due to wear can be are shifted without forming a gap in the direction of wear progress.

In the wear sensor according to the first aspect of the present invention described above, the plurality of detection wiring parts may be arranged so as to be inclined with respect to the front end surface.

Since an area in which wiring widths of the continuity check wirings decrease toward the corners of the distal ends of the continuity check wirings located near the other side surface decreases, a sudden change in resistance value may be generated upon disconnection. As a result, an S / N ratio can be improved and thus the measurement accuracy of wear can be improved.

When the continuity test wirings 21st to 23 and the ground wiring 26th exhibit no electrical continuity and the continuity test wiring 24 and the ground wiring 26th which have electrical continuity becomes a sum of the first wear value B. and a value three times the second wear value C. is obtained as the wear value E as described in equation (3). $$\text{E.}=\text{B.}+3\times \text{C.}$$

In this way, the wear value acquisition unit acquires 48C the wear value E of the wear transmitter 8th since an initial state (a state in which the front end surface 11a of the insulating substrate 11 due to the rotation body 4th has not been worn).

The wear and tear value acquisition unit 48C becomes a wear value F of the bearing main body 6th near the wear surface 6a based on the wear value E of the wear sensor 8th .

Therefore, the amount of wear F of the bearing main body becomes 6th equal to the wear value E of the wear sensor 8th . Therefore, the amount of wear F of the bearing main body 6th can be obtained by taking the wear value E of the wear sensor 8th is obtained.

According to the wear sensor 8th the first embodiment has the wear sensor 8th the wiring group 12 with the continuity test wiring 21st to 25th and the ground wiring 26th which at intervals in the X direction from the side surface 11b to the side surface 11c of the insulating substrate 11 and the wear detection wiring 13 attached to the wiring formation surface 11d of the insulating substrate 11 is formed and the distal ends 21A to 25A of the continuity test wiring 21st to 25th and the distal end 26A the ground wiring 26th which is on the side of the front end surface 11a of the insulating substrate 11 are arranged, connects, on. The distal ends 21A to 26A are arranged so that the respective distal end is from the side surface 11b to the side surface 11c farther from the front end surface 11a to the rear end surface of the insulating substrate 11 away. The Wear detection wiring 13 has the detection wiring parts 31 to 35 on, each electrically connected to the distal ends of two wirings that are below the continuity test wirings 21st to 25th adjoin each other, and the grounding wiring 26th are connected. Accordingly, it is not necessary to leave a gap for electrically insulating between the detection wiring parts in the direction of wear progress A. to train.

Thereby, there can be a distance in the longitudinal direction (Y direction) of the insulating substrate 11 from a position where one detection wiring part has been removed due to wear to a position where the next detection wiring part is removed, the resolution may be reduced D. that of the wear measurement can be improved.

Portions of the respective detection wiring parts 31 to 35 that are adjacent to each other can be arranged so that they are in the direction of wear and tear A. overlap and this can cause the resolution D. of the wear measurement can be made smaller than a width of the detection wiring part (a width in the Y direction).

The detection wiring parts 31 to 35 are arranged to extend in a direction perpendicular to the direction of wear progression A. extending one form of wear detection wiring 13 is designed to have a stepped shape, thereby a timing at which each of the detection wiring parts 31 to 35 removed due to wear, can be shifted without leaving a gap in the direction of wear progress A. to train.

Second embodiment

A method of adjusting a bearing 5 a second embodiment is made with reference to FIG 4th and 5 described. In the second embodiment, a case will be described as an example in which the wear sensor 8th of the first embodiment on a bearing main body 6th is set.

An in 4th Depicted J indicates an area in which a wear value cannot be detected (hereinafter referred to as an area J designated). In 4th and 5 are the same components as those in 1 and 2 structure shown by the same reference numerals.

First, an in 4th illustrated step of the wear sensor 8th in a receiving part 6A of the storage main body 6th arranged so that a portion of a distal end of the wear sensor 8th from a wear surface 6a of the storage main body 6th protrudes (sensor arrangement step).

In the sensor arranging step, a portion of the detection wiring parts 31 to 35 (For example, the detection wiring parts 32 to 35 in the case of 4th ) in the receiving part 6A and the remaining portion (for example, the detection wiring part 31 in the case of 4th ) is outside of the receiving part 6A arranged.

Next, in an in 5 illustrated step the distal end side of the wear sensor 8th by the wear surface 6a and the side of the wear surface 6a of the storage main body 6th protrudes, scraped off so that the front end surface 11a of the wear sensor 8th and the wear surface 6a are coplanar to each other (processing step). In the processing step, not only the insulating substrate is used 11 but also a section of the wiring group 12 scraped off.

In the process of scraping a portion of the wear sensor 8th and the storage main body 6th For example, a method such as a cutting method or a milling method can be used.

Next, a state of electrical continuity between the continuity check wiring and the ground wiring using a wear value obtaining device will be discussed 9 is checked to identify the detection wiring that has been removed (the detection wiring 31 in the case of the 5 ) (Continuity check step).

In the continuity check step, a voltage is sequentially applied between the continuity check wirings 21st to 25th and the ground wiring 26th is applied to check whether or not a current is flowing therethrough, thereby identifying the remote detection wiring part.

In the case of 5 flows as the continuity test wiring 21st of a structure that will wear the remaining wiring 13 and the continuity test wirings 22nd to 25th includes, is disconnected, no power between the continuity test wiring 21st and the ground wiring 26th . Therefore, in this part, it is to be determined that the detection wiring part 31 was removed.

In contrast, in the case of 5 as the structure that the remaining wear detection wiring 13 and the continuity test wirings 22nd to 25th includes, is integrated, a current between the continuity test wiring 22nd and the ground wiring 26th . Therefore, in this case, it is to be determined that the detection wiring part 32 remains in a state that the continuity check wiring 22nd and the continuity test wiring 23 can connect.

Accordingly, if the setting of the wear sensor 8th to or on the storage main body 6th is completed, the detection wiring parts showing a wear value of the wear surface 6a can detect the detection wiring parts 32 to 35 , the detection wiring part 31 is excluded or excluded.

According to the procedure for adjusting the storage 5 In the second embodiment, the method includes the above-described sensor arranging step, the processing step, and the continuity checking step, wherein the area J (an area from the front end surface 11a of the insulating substrate 11 to the detection wiring part 31 that is closest to the front end surface 11a is arranged) at which a wear value cannot be detected, can be removed, and the detection wiring part 31 removed by scraping can be identified.

This allows even if the wear value of the wear surface 6a of the storage main body 6th is small, the wear value can be obtained.

Further, although in the second embodiment, a case has been described as an example in which the wear sensor 8th of the first embodiment in the storage main body 6th is set, the same effects as those of the second embodiment can be obtained even if the wear sensor 55 of the modified example of the first embodiment in the bearing main body 6th instead of the wear sensor 8th is set.
