Description

Technical Field

[0001] The present application relates to the technical field of torque sensors, and more particularly to a rotor unit retainer for a drive shaft. Background Art

[0002] During the development of automotive products, the torque of the drive shaft is an important basis for the design of the driveline structure. Since the drive shaft rotates at a high speed during normal operation, a torque telemeter is usually used to measure the torque of the drive shaft.

[0003] During the use of the torque telemeter, the rotor unit and the battery unit need to be fixed on the drive shaft to achieve stable power supply and signal communication for the test unit. In common experimental devices currently, there is a lack of a component for fixing the rotor unit to the drive shaft. In daily work, engineers often wind the rotor unit and the battery around the drive shaft with cloth-based tape. Such installation is likely to result in insecure fixation, and when replacing the battery, this work needs to be repeated, wasting the time of engineers and having low efficiency. Utility Model Content

[0023] The following detailed embodiments are provided to assist the reader in obtaining a comprehensive understanding of the methods, apparatuses, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatuses, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein. Rather, changes that will be apparent after understanding the disclosure of this application may be made, except for operations that must occur in a particular order. In addition, descriptions of features known in the art may be omitted for increased clarity and conciseness.

[0024] The features described herein may be implemented in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, apparatuses, and / or systems described herein that will be apparent after understanding the disclosure of this application.

[0025] Throughout the specification, when an element (such as a layer, region, or substrate) is described as "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, it may be directly "on," "connected to," "coupled to," "above," or "covering" the other element, or there may be one or more other elements intervening therebetween. In contrast, when an element is described as "directly on" another element, "directly connected to" another element, "directly coupled to" another element, "directly above" another element, or "directly covering" another element, there may be no other elements intervening therebetween.

[0026] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0027] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or sections, these components, elements, regions, layers, or sections are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or section from another.

Thus, the term "above" includes both the orientation of "above" and "below" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relationship terms used herein will be interpreted accordingly.

[0029] The terms used herein are for the purpose of describing various examples only and are not intended to limit the examples. Unless the context clearly dictates otherwise, the singular forms are also intended to include the plural forms. The terms "comprises", "comprising", and "having" list the stated features, quantities, operations, components, elements, and / or combinations thereof that exist, but do not preclude the existence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0030] Due to manufacturing techniques and / or tolerances, variations in the shapes shown in the figures may occur. Thus, the examples described herein are not limited to the specific shapes shown in the figures, but include changes in shape that occur during manufacturing.

[0031] The features of the examples described herein may be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have a variety of configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0032] The present utility model provides a rotor unit retainer for a transmission shaft, as Figures 1 to 4 shown, the rotor unit retainer for the transmission shaft includes a first retainer 1 and a second retainer 2.

[0033] In the following description, reference will be made to Figures 1 to 4 the specific structure of the above components of the rotor unit retainer for the transmission shaft and the connection relationship of the above components will be specifically described.

[0034] As Figures 1 to 4 shown, in the embodiment, the first retainer 1 can be arranged on the first side in the radial direction of the transmission shaft 3. The second retainer 2 can be arranged on the second side in the radial direction of the transmission shaft 3. The first retainer 1 can be arranged opposite to the second retainer 2, and the first retainer 1 and the second retainer 2 can be connected and fixedly arranged around the transmission shaft 3. The rotor unit can be installed on the first retainer 1 and the second retainer 2, and thus the rotor unit can be firmly fixed to the side of the transmission shaft 3 indirectly to test the torque of the transmission shaft 3.

[0035] Preferably, as Figures 1 to 4 shown, in the embodiment, the first retainer 1 and the second retainer 2 can be formed into semi-circular rings. Specifically, the first retainer 1 can be formed into a half ring of 180° (or close to 180°). The second retainer 2 can also be formed into a half ring of 180° (or close to 180°). The shapes and sizes of the first retainer 1 and the second retainer 2 can be the same, so that the first retainer 1 and the second retainer 2 can form a complete ring when joined at the ends to be fixedly arranged around the outer periphery of the transmission shaft 3. The number of rotor units can be two, and the two rotor units can be respectively installed on the first retainer 1 and the second retainer 2, so that the rotor units can better test the torque of the transmission shaft 3.

[0036] Not limited to this, the first retainer and the second retainer being both formed into semi-circular rings is only a preferred case in the embodiment. As long as the rotor unit can test the torque of the transmission shaft, the first retainer and the second retainer can also be formed into other cases. For example: the first retainer is formed into a 300° ring, and the second retainer is formed into a 60° ring. In this case, the first retainer can be disassembled for easy installation on the rotating shaft, and the rotor units can all be installed on the first retainer.

[0037] Preferably, as Figures 1 to 4As shown, in the embodiment, threaded holes 4 may be provided at the ends of the first holding member 1 and the second holding member 2. Specifically, the cross-sections of the ends of the first holding member 1 and the second holding member 2 may be formed as rectangles, and the threaded holes 4 may be opened at the ends of the first holding member 1 and the second holding member 2. And when the ends of the first holding member 1 and the second holding member 2 are arranged oppositely (i.e., when the ends of the first holding member 1 and the second holding member 2 are fitted together), the positions of the threaded holes 4 at the end of the first holding member 1 correspond to the positions of the threaded holes 4 at the end of the second holding member 2. The first holding member 1 and the second holding member 2 may be connected by bolts, and the two ends of the bolts may be respectively installed in the threaded holes 4 of the first holding member 1 and the threaded holes 4 of the second holding member 2, thereby connecting the ends of the first holding member 1 and the second holding member 2.

[0038] More preferably, as Figures 1 to 4 shown, in the embodiment, the first holding member 1 may be provided with four threaded holes 4. That is, two threaded holes 4 may be provided at each end of the first holding member 1. Correspondingly, the second holding member 2 may be provided with four threaded holes 4, and two threaded holes 4 are provided at each end of the second holding member 2.

[0039] In addition, preferably, in the embodiment, the inner diameters of the first holding member 1 and the second holding member 2 (i.e., the diameters of the inner rings of the semi-circular rings) may be slightly smaller than the outer diameter of the transmission shaft 3 (i.e., the diameter of the transmission shaft 3). In this case, the first holding member 1 and the second holding member 2 cannot be completely buckled on both sides of the transmission shaft 3. A gap is formed between the connected ends of the first holding member 1 and the second holding member 2, and the size of the gap can be adjusted by bolts, thereby adjusting the locking degree between the rotor unit holder for the transmission shaft and the transmission shaft 3.

[0040] Preferably, as Figures 1 to 4 shown, in the embodiment, rotor mounting grooves 5 may be opened on the sides of the first holding member 1 and the second holding member 2 away from the transmission shaft 3, and the rotor mounting grooves 5 are used for mounting the rotor unit. Specifically, the rotor mounting grooves 5 may be opened on the outer arc surfaces of the first holding member 1 and the second holding member 2. The rotor mounting grooves 5 may be square grooves, and the rotor unit may be installed in the rotor mounting grooves 5.

[0041] Furthermore, preferably, as Figure 2 and Figure 3As shown, in the embodiment, a first wire hole 50 for communicating with the outside may be opened on the side of the rotor mounting groove 5. Specifically, the first wire hole 50 may be provided at one end in the length direction of the rotor mounting groove 5. The first wire hole 50 may communicate the rotor mounting groove 5 with the axial ends of the first holder 1 and the second holder 2. With such a setting, the wire can extend into the rotor mounting groove 5 through the first wire hole 50 to connect the rotor unit.

[0042] In addition, preferably, as Figures 1 to 3 shown, in the embodiment, a cover plate 7 may be provided at the notch of the rotor mounting groove 5. Specifically, a rectangular cover plate 7 with equal dimensions may be provided at the notch of the rotor mounting groove 5. Screw holes may be opened on the first holder 1 and the second holder 2, and the cover plate 7 may be mounted at the notch of the rotor mounting groove 5 by screws to prevent the rotor unit from being thrown out during the movement of the transmission shaft 3.

[0043] Preferably, as Figures 2 to 4 shown, in the embodiment, battery mounting grooves 6 may be opened on the sides of the first holder 1 and the second holder 2 close to the transmission shaft 3 for mounting batteries. Specifically, the battery mounting grooves 6 may be opened on the inner arc surfaces of the first holder 1 and the second holder 2. The battery mounting grooves 6 may be square grooves, and the batteries may be installed in the rotor mounting groove 5.

[0044] Furthermore, preferably, as Figures 2 to 4 shown, in the embodiment, second wire holes 60 for communicating with the outside may be opened on the sides of the battery mounting grooves 6. Specifically, the second wire holes 60 may be provided at both ends in the length direction of the battery mounting grooves 6. That is, the second wire holes 60 may communicate the battery mounting grooves 6 with the axial ends of the first holder 1 and the second holder 2. With such a setting, the wires connected to the batteries can extend out of the battery mounting grooves 6 through the second wire holes 60, and the wires can be used to connect the batteries and the rotor units.

[0045] In addition, preferably, in the embodiment, the rotor unit retainer for the transmission shaft may further include a counterweight. The counterweight may be installed in the battery mounting groove 6. Specifically, a card slot may be provided in the battery mounting groove 6, and the counterweight may be clamped in the card slot to ensure the uniform weight of the first holder 1 and the second holder 2 and keep the transmission shaft 3 balanced during rotation. In addition, a cover plate (not shown) may also be installed at the notch of the battery mounting groove 6.

[0046] During use, the first retaining member 1 and the second retaining member 2 of the rotor unit retainer for the transmission shaft are fastened to the transmission shaft 3 by bolts. The first retaining member 1 and the second retaining member 2 can rotate with the transmission shaft 3 and protect the battery and the rotor unit inside. The battery in the battery mounting groove 6 is connected to the rotor in the rotor mounting groove 5 by a wire. This arrangement enables the rotor unit and the battery to be firmly fixed to the transmission shaft 3.
