FIG. 1 schematically illustrates a bearing assembly according to an embodiment of the invention. A bearing assembly according to an embodiment of the invention is described below with reference to fig. 1.

As shown in fig. 1, a bearing assembly 10 according to an embodiment of the present invention includes a bearing module and a temperature measuring module for detecting a temperature of the bearing module. In the embodiment shown in fig. 1, the bearing module is configured as a rolling bearing comprising an inner ring 1, a cage 2, rolling bodies 3 and an outer ring 4, and the thermometry module comprises a first thermometry module 5 for detecting the temperature of the inner ring 1 and a second thermometry module 6 for detecting the temperature of the outer ring 4. It is noted that in the embodiment shown in fig. 1, both the inner ring 1 and the outer ring 4 are configured as rotating elements. The first and second temperature measuring modules 5 and 6 are described in detail below with reference to the accompanying drawings.

Fig. 2, 3(a), 3(b), 4(a) and 4(b) schematically illustrate a first thermometry module in a bearing assembly according to an embodiment of the present invention. The first thermometric module in the bearing assembly according to the embodiment of the present invention will be described in detail below with reference to fig. 2, 3(a), 3(b), 4(a) and 4 (b).

As shown in fig. 2, the first thermometric module 5 includes a first mounting plate 501, a first wireless passive sensor 502, and a first cover 503. In particular, the first wireless passive sensor 502 is mounted in the first cover 503, and as can be clearly seen from fig. 2, a receiving portion for receiving the first wireless passive sensor 502 is provided on the first cover 503, and when it is required to mount the first wireless passive sensor 502 on the first cover 503, the first wireless passive sensor 502 is positioned in the receiving portion of the first cover 503. Moreover, a through hole is provided in the first cover 503, and the first cover 503 and the first wireless passive sensor 502 are mounted on the first mounting plate 501 together by a screw 504 through the through hole in the first cover 503. It can be understood that in the bearing assembly according to the embodiment of the present invention, the first cover 503 of the first thermometric module 5 is used to cover the first wireless passive sensor 502 to protect the first wireless passive sensor 502 from foreign objects such as dust.

The description continues with reference to fig. 2. As shown in fig. 2, the first mounting plate 501 is configured to include a first area (upper area) 5011 and a second area (lower area) 5012. The first area 5011 is used to mount the first wireless passive sensor 502, and the second area 5012 is used to mount a mounting portion to an end face of the inner ring 1. The second area 5012 is provided with first positioning portions 501a, the first positioning portions 501a are specifically provided as positioning grooves and are provided on both sides of the second area 5012, and accordingly, the end surface of the inner ring 1 is provided with second positioning portions (not shown) that are engaged with the first positioning portions 501a, the second positioning portions are specifically provided as positioning projections, and the first positioning portions 501a and the second positioning portions cooperate to position the first mounting plate 501 in the radial direction of the rolling bearing. In other words, the positioning of the first temperature measuring module 5 in the radial direction of the rolling bearing is shown in fig. 3(a), and since the up-down direction is the radial direction and the left-right direction is the axial direction in the cross-sectional view of the rolling bearing shown in fig. 3(a), the positioning in the radial direction of the rolling bearing is specifically the positioning in the up-down direction in fig. 3 (a). And, the radial positioning of the first mounting plate 501 on the right end surface of the inner ring 1 is realized by the cooperation of the first positioning portion 501a and the second positioning portion as described above, thereby realizing the positioning of the first temperature measurement module 5 in the radial direction on the rolling bearing. Fig. 3(b) is a partial enlarged view of a portion a in fig. 3(a), and it can be seen from fig. 3(b) that the first wireless passive sensor 502 of the first temperature measurement module 5 is positioned radially between the inner ring 1 and the outer ring 4 to ensure smooth signal transmission of the first wireless passive sensor 502. The signal is then read and processed by a read antenna and read module, which process is understood with reference to the prior art and is not described in detail herein. It is to be understood that the above description is merely an example, and the bearing assembly of the present invention is not limited thereto, for example, the forms of the first positioning portion and the second positioning portion are not limited to the above embodiment, and the first positioning portion may be provided as a positioning protrusion and the second positioning portion may be provided as a positioning groove; for another example, the first positioning portion is not limited to be disposed on two sides of the second region, and may be disposed at other positions of the mounting plate according to actual conditions; for another example, the first wireless passive sensor may be positioned differently in the radial direction of the bearing according to actual operating conditions.

The description continues with reference to fig. 2. As shown in fig. 2, the first mounting board 501 includes a first side (left side) and a second side (right side) opposite to each other, the first wireless passive sensor 502 is mounted at the first side of the first mounting board 501 at a first area 5011, and the first positioning portion 501a is mounted at the second side opposite to the first side at a second area 5012. The second side of the mounting plate 501 at the second area 5012 will be used for mounting to the mounting portion of the inner ring 1, and therefore the first wireless passive sensor 502 is arranged opposite to the mounting surface of the first mounting plate 501, which is advantageous in that the first wireless passive sensor 502 is spaced a distance from the cage 2 of the rolling bearing, thus ensuring that the first thermometric module 5 does not interfere with the cage 2 of the rolling bearing to affect the operation of the rolling bearing, as is also clearly shown in fig. 3 (b).

Further, as shown in fig. 2, at the second area 5012, the second side face of the first mounting plate 501 is configured to have a convex arc-face profile, and the mounting portion of the inner ring 1 is configured to have a concave arc-face profile adapted to the convex arc-face profile. Specifically, fig. 4(a) shows that the first temperature measuring module 5 is mounted on the rolling bearing, fig. 4(B) is a partially enlarged view of a portion B in fig. 4(a), and it can be clearly seen from fig. 4(B) that the convex cambered profile portion of the first mounting plate 501 is connected with the concave cambered profile portion of the inner ring 1. It will be appreciated that the above-described form of the mounting portion of the inner ring of the rolling bearing is advantageous for the occurrence of stress concentration during the hardening process of the inner ring, but this is merely an example and the bearing assembly of the present invention is not limited thereto, and for example, the mounting portion on the inner ring may also be provided in the form of a dovetail groove, a trapezoidal groove, or the like. As an example, the convex cambered profile portion of the first mounting plate 501 and the concave cambered profile portion of the inner ring 1 are connected in an adhesive manner, but this is merely an example, the bearing assembly of the present invention is not limited thereto, and the mounting plate and the inner ring may be connected in other manners.

FIG. 5 schematically illustrates a second thermometric module in a bearing assembly according to an embodiment of the invention. A second thermometric module in a bearing assembly according to an embodiment of the invention is described below with reference to figure 5.

As shown in fig. 5, second thermometric module 6 includes second mounting plate 601, second wireless passive sensor 602, and second cover 603. In particular, second wireless passive sensor 602 is mounted in second cover 603, and as can be clearly seen from fig. 5, second cover 603 is provided with a receiving portion for receiving second wireless passive sensor 602, and when it is desired to mount second wireless passive sensor 602 in second cover 603, second wireless passive sensor 602 is positioned in the receiving portion of second cover 603. Furthermore, a through hole is provided in second cover 603, and second cover 603 and second wireless passive sensor 602 are mounted together on second mounting plate 601 by screws 604 through the through hole in second cover 603. Further, the end face of the outer ring 4 is provided with a mounting portion provided as a mounting hole into which the second mounting plate 601 is mounted via a screw, for example.

Therefore, in the bearing assembly of the present invention, the sensor in the thermometric module is defined as a wireless passive sensor, thus eliminating the need for an external power source, thereby eliminating the need to frequently replace the battery of the sensor. In addition, the temperature measuring module in the bearing assembly is mounted on the end face of the inner ring and/or the outer ring of the bearing through the mounting plate, so that the occupied space is small, and the interchangeability with surrounding parts is good. Therefore, the bearing assembly of the present invention has the advantages of small volume, low maintenance requirements and good interchangeability.

It will be appreciated by those skilled in the art that although the bearing modules in the bearing assembly of the present invention described above with reference to the drawings are specifically rolling bearings, this is merely an example and the bearing modules of the bearing assembly of the present invention are not limited thereto. The inner ring and the outer ring of the rolling bearing in the bearing assembly of the present invention are not limited to both being a rotating member, and for example, only the outer ring or the inner ring may be provided as a rotating member. For another example, the radially inner and outer members included in the bearing module in the bearing assembly of the present invention are not limited to the inner and outer rings of the rolling bearing, and the bearing module of the present invention may include the radially inner and outer members each cooperating with one outer member to achieve the restriction of the movement between the outer members independently of each other, for example, the bearing module may be a sliding bearing.

As described above, although the exemplary embodiments of the present invention have been described in the description with reference to the drawings, the present invention is not limited to the above-described embodiments, and the scope of the present invention should be defined by the claims and their equivalents.
