Therefore, unless the claims expressly state otherwise, specific dimensions and other physical characteristics related to the embodiments disclosed herein should not be considered limiting.

[0030] Systems and devices

[0031] exist Figure 1 , a system 100 is shown for measuring the angle adjustment of a hook spanner 10 to precisely tighten a bearing 20 onto a shaft 30. The shaft 30 may include a threaded portion 40 and a tapered portion 47. The threaded portion 40 includes a slot 49, the purpose of which will be disclosed later in this specification. The system 100 also provides a bearing lock nut 50 that is tightened by the hook spanner 10.

[0032] Now refer to Figure 1 - Figure 2 , the system 100 may further provide an apparatus 110. Figure 2 1 . The device 110 itself is shown in FIG. The device 110 provides a hook wrench 10 that includes a lever arm 15 and an engagement portion 17. The engagement portion 17 of the hook wrench 10 is configured to engage at least four indentations 52 disposed on an outer surface of the bearing lock nut 50. The engagement portion 17 includes a protrusion 19 that interlocks with one of the at least four indentations 52. Thus, this interlocking arrangement provides a latching grip between the hook wrench 10 and the bearing lock nut 50.

[0033] The lever arm 15 is configured to have a storage clamping device 60 mounted thereon. A portable communication device or smartphone 70 is secured in place by the storage clamping device 60. The storage clamping device 60 provides a sliding adjustment mechanism. This sliding adjustment mechanism enables the smartphone to be mounted in both horizontal and vertical orientations (as indicated by the arrows), facilitating the mounting of smartphones of varying sizes.

[0034] An application (App) 72 or a mobile application software 72 designed to run on a smart phone and other mobile devices is stored in the memory 930 of the smart phone 70. The smart phone can also provide a microprocessor 932, which operates together with the memory 930 to execute the functions of the App. Most importantly for the present invention, the App 72 provides a built-in inclinometer 90 and a lookup data table 74, and the lookup data table 74 is displayed on the display 77 (see Figure 11A 、 Figure 11B and Figure 11C ). The lookup data table 74 displays the correct bearing lock nut drive up angle based on the bearing type input into the smart phone.

[0035] Now referring to Figure 3 - Figure 5 , the bearing 20 has an inner ring 21, and the inner ring 21 includes a tapered hole 22. During assembly, the tapered hole 22 of the bearing 20 slides gently on the threaded portion 40 of the shaft 30 and rests on the tapered portion 47 of the shaft 30. The bearing lock nut 50 has a threaded interior 54. The threaded interior 54 of the bearing lock nut 50 mates with the threaded portion 40 of the shaft 30.

[0036] The bearing lock nut 50 is screwed onto the threaded portion 40 of the shaft 30 until the inner side 56 of the bearing lock nut 50 and the outer side of the bearing inner ring 24 contact each other. The bearing lock nut 50 is "hand tightened" until the inner side 56 of the bearing lock nut 50 and the outer side of the bearing just begin to contact and only very light force is generated to drive the bearing. In addition, depending on the material of the construction, the contact between the inner side 56 of the bearing lock nut 50 and the outer side of the bearing inner ring 24 can provide metal-to-metal contact.

[0037] Once the inner side 56 of the bearing lock nut 50 is manually tightened against the outer side of the bearing inner ring 24, the position of the bearing 20 on the tapered portion 47 of the shaft 30 is initially set. The assembly can be seen in the cross-section shown in Figure 6 .

[0038] At this time, the bearing lock nut 50 is removed, so that the spacer 92 and the lock washer 82 can be inserted onto the shaft, and the spacer 92 and the lock washer 82 are gently pressed against the bearing inner ring 24 of the bearing 20. See Figure 6 - Figure 9。The radially inwardly projecting tab 84 of the lock washer 82 engages the groove 49 of the threaded portion 40 of the shaft. This engagement prevents the lock washer from spinning and serves to secure the lock nut to the lock washer upon tightening. The spacer and lock washer are now installed, and then the lock nut is manually screwed onto the threaded portion of the shaft. Again, "hand tighten" the bearing lock nut 50 until the inner side 56 of the bearing lock nut 50 and the outer side of the bearing inner ring just begin to contact and only a very light force is generated between the two to drive up against the bearing.

[0039] Now, the bearing with a tapered inner ring is initially set onto the tapered portion of the shaft, and the spacer, lock washer, and lock nut are manually tightened in place, and it will be ready to utilize the device 110 for precisely securing the bearing to the shaft as shown in Figure 10 .

[0040] Now refer to Figure 10 - Figure 13 , a Full Qwerty Keypad FQK for entering bearing type information is shown. The bearing type information identifies the correct lock nut drive angle. The correct lock nut drive angle is shown on the display 77 of the smart phone 70. See specifically Figure 11A , Figure 11B and Figure 11C . The lookup data sheet 74 displays the correct bearing lock nut drive angle based on the bearing type input into the smart phone. In response, the correct installation angle / drive position of the bearing lock nut 50 is shown on the built-in inclinometer 90.

[0041] When a force F is applied to the lever arm 15 of the hook wrench, the force causes the hook wrench to rotate. When the force F is applied to the outer end of the lever arm, the hook wrench starts to rotate the bearing lock nut. When the wrench starts to rotate, the inclinometer responds in real time and displays the updated lock nut drive angle position in a clockwise manner. Thus, while (the wrench) is rotating, monitor the installation angle / drive position by referring to the content shown on the built-in inclinometer 90. When the correct installation angle / drive position is indicated on the inclinometer, stop applying the force F to the lever arm.

[0042] The correct installation angle / drive position can be indicated in various ways. First, as shown in Figure 11B , a graph of the drive angle can be shown. Here, the initial starting point is indicated, and when the spanner wrench rotates, the current angle α changes. When the arrow indicates reaching the goal, the drive angle is reached.

[0043] In Figure 11C the configuration shown, the starting angle or the current angle can be displayed in the upper part of the built-in inclinometer 90, and the target angle can be displayed in the lower part 94 of the built-in inclinometer 90.

[0044] In Figure 12 - Figure 13 the configuration shown, the starting angle or the current angle can be displayed as a vertically extending arrow on the display of the inclinometer. Here, a color is displayed on the built-in inclinometer 90 to indicate the current installation angle / driving position. For example, the green-colored part on the inclinometer can indicate "continue to rotate the hook wrench". The yellow part can indicate "you are approaching the desired driving angle target", and the red part can indicate "the target has been reached". In this way, the vertical arrow remains vertically extended, and when the wrench rotates, the colored part moves towards the target.

[0045] Method

[0046] A method 200 for measuring the angular adjustment of a hook wrench to accurately fix a bearing to a shaft will now be disclosed, the shaft having a tapered portion and a threaded portion.

[0047] In a first step 210, the method includes sliding the bearing onto the tapered portion of the shaft. Here, the bearing is gently slid upwards onto the tapered portion of the shaft. This is opposite to being tamped in place.

[0048] In a second step 220, the method includes screwing a lock nut onto the threaded portion of the shaft. The lock nut is screwed onto the threaded portion of the shaft until the inner side of the lock nut and the outer side of the inner ring of the bearing start to contact each other.

[0049] In the next step 230, the method provides removing the lock nut from the threaded portion. This is done in anticipation of the next step 240, which provides placing a spacer on the threaded portion of the shaft and pressing the spacer against the bearing. Further, the method provides placing a lock washer on the threaded portion of the shaft and pressing the lock washer against the spacer in step 250.

[0050] In the next step 260, the method provides attaching the hook wrench to the lock nut. As disclosed previously, the engaging portion of the hook wrench is configured to engage at least four notches provided on the outer surface of the bearing lock nut. The engaging portion includes a protrusion that interlocks with one of the at least four notches. In this way, this interlocking configuration provides a latch grip between the hook wrench and the lock nut.

[0051] Then, the method includes step 270: providing a mounting device for a portable computing device and arranging the mounting device on the lever arm of the hook wrench.

[0052] Then, the method calls step 280: Attach the portable computing device to the installation device, the computing device having a software application including a built-in inclinometer.

[0053] The method further includes step 290: Initialize the software application including the built-in inclinometer.

[0054] In step 300, perform entering identification information regarding the type of bearing to be fastened into the display disposed on the computing device.

[0055] The method includes step 310: Display the correct installation angle / driving position of the component on the built-in inclinometer.

[0056] The method includes step 320: Apply a force F to the lever arm and rotate the hook wrench while monitoring the installation angle / driving position displayed on the inclinometer.

[0057] Finally, the method provides step 330: When the correct installation angle / driving position is indicated on the clinometer, stop applying the force F to the lever arm. Thus, when the correct installation angle / driving position is displayed on the display, the method is completed and the force stops.

[0058] Since many modifications, variations and changes in detail can be made to the described preferred embodiments and methods of the present invention, it is intended that all matter shown in the foregoing description and in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Accordingly, the scope of the present invention is to be determined by the appended claims and their legal equivalents.
