Abstract

A system for measuring angle adjustment of a hookspanner wrench to accurately tighten a bearing onto a shaft having a threaded and tapered portion. The system including a device providing a hookspanner wrench having a lever arm and an engaging portion, the engaging portion of the hookspanner wrench configured to engage a bearing locking nut, the lever arm configured to mount a storage clamping device fixed thereto, a smartphone secured in place by the storage clamping device, and a specialized application stored on the smartphone that provides a built-in inclinometer and look up data tables. A method for measuring angle adjustment of a hookspanner wrench to accurately tighten a bearing onto a shaft having a threaded and tapered portion as well.

First claim

The invention claimed is:

1. A system for measuring angle adjustment of a hookspanner wrench to accurately tighten a bearing onto a shaft having a threaded and tapered portion, the system comprising:
a hookspanner wrench having a lever arm and an engaging portion, the engaging portion configured to engage a bearing locking nut,
a storage clamping device comprising a clamp, the storage clamping device being positioned on the lever arm,
a smartphone secured in place by the clamp of the storage clamping device, and
a specialized application stored on the smartphone that provides a built-in inclinometer and look up data tables.

2. The system for measuring angle adjustment of a hookspanner wrench according to claim 1 , wherein the look up data tables display a correct bearing locking nut drive up angle based on a bearing type inputted into the smartphone.

3. The system for measuring angle adjustment of a hookspanner wrench according to claim 2 , wherein when a force is applied to an outer end of the lever arm and the hookspanner wrench begins to rotate the bearing locking nut, and wherein the inclinometer responds in real time and displays an updated locking nut drive up angle position.

4. The system for measuring angle adjustment of a hookspanner wrench according to claim 3 , wherein the application of force applied to the lever arm is stopped when the correct mounting angle/drive up position is indicated as being obtained on the inclinometer.

5. The system for measuring angle adjustment of a hookspanner wrench according to claim 1 , wherein the storage clamping device provides an adjustment mechanism that enables installation of the smartphone in both a horizontal and vertical direction to facilitate different sized smartphones.

6. The system for measuring angle adjustment of a hookspanner wrench according to claim 1 , wherein one of an angle, a number, and a color is displayed on the inclinometer to indicate the mounting angle/drive up position has been obtained.

7. The system for measuring angle adjustment of a hookspanner wrench according to claim 1 , further comprises a Full Qwerty Keypad for entering bearing type information that identifies a correct locking nut drive up angle on at least one display of the computing device.

8. A system for measuring angle adjustment of a hookspanner wrench to accurately tighten a bearing onto a shaft having a threaded and tapered portion, the system comprising:
a device providing a hookspanner wrench having a lever arm and an engaging portion, the engaging portion of the hookspanner wrench configured to engage a bearing locking nut,
a storage clamping device comprising a clamp, the storage clamping device being positioned on the lever arm,
a smartphone secured in place by the clamp of the storage clamping device, a specialized application stored on the smartphone that provides a built-in inclinometer and look up data tables,
the bearing having an inner race and a tapered bore being mounted over an outer unthreaded portion of the shaft,
the bearing locking nut having a threaded inner portion and screwed onto a threaded portion of the shaft, the bearing locking nut screwed onto the threaded portion of the shaft until an inner side of the locking nut and an outer side of the bearing inner race contact each other,
an interlocking arrangement providing a meshing grip between the hookspanner wrench and the locking nut,
information regarding a type of bearing to be secured being entered into the smartphone, and wherein
in response, a correct mounting angle/drive up position of the lock nut is displayed on the built-in inclinometer,
a force F applied to the lever portion of the hookspanner wrench causes the hookspanner wrench to rotate while the mounting angle/drive up position is monitored against what is displayed on the inclinometer and wherein
the application of force to the lever portion is stopped when the correct mounting angle/drive up position is indicated as being obtained on the inclinometer.

9. The system for measuring angle adjustment of a hookspanner wrench to accurately secure a bearing onto a shaft according to claim 8 , wherein the contact between an inner side of the locking nut and an outer side of the bearing inner race is a metal to metal contact.

10. A method of measuring angle adjustment of a hookspanner wrench to accurately secure a bearing onto a shaft, the shaft having a threaded and tapered portion, the method comprising:
sliding the bearing onto the tapered portion of the shaft,
screwing a lock nut onto the threaded portion of the shaft until an inner side of the locking nut and an outer side of the bearing inner race contact each other,
removing the locking nut off of the threaded portion,
placing a spacer over the threaded portion of the shaft and up against the bearing,
placing a lock washer over the threaded portion of the shaft and up against the spacer,
attaching the hookspanner wrench onto the locking nut,
providing a mounting device for a portable computing device disposed on a lever portion of the hookspanner wrench,
attaching the portable computing device onto the mounting device, the computing device having a software application that includes a built-in inclinometer,
initializing the software application that includes the built-in inclinometer,
inputting identifying information into a display disposed on the computing device regarding a bearing type to be tightened,
displaying a correct mounting angle/drive up position of the component on the built-in inclinometer,
applying force to the lever portion and rotating the hookspanner wrench while simultaneously monitoring the mounting angle/drive up position displayed on the inclinometer, and
stopping the application of force to the lever portion when the correct mounting angle/drive up position is indicated as being obtained on the inclinometer.

11. A device for tightening a bearing onto a shaft, the device comprising:
a hookspanner wrench comprising:
an engaging portion configured to engage a locking nut of the bearing,
a lever arm which extends radially away from the engaging portion, and

a storage clamping device attached to the lever arm of the hookspanner wrench, the storage clamping device configured to hold a smartphone comprising a front surface with a user interface thereon, a rear surface, a bottom end, and a top end, the storage clamping device comprising:
a first clamp end configured to abut the bottom end of the smartphone,
a lateral wall extending from the first clamp end and configured to abut the rear surface of the smart phone, and
a second clamp end slidably connected to the lateral wall and configured to abut the top end of the smartphone, the position of the first clamp end relative to the second clamp end being adjustable to facilitate clamping after the smartphone is positioned against the first clamp end and against the lateral wall to secure the smartphone in place.

12. A system for tightening a bearing onto a shaft, comprising:
the device of claim 11 , and
the smartphone positioned in the clamp, an application stored on the smartphone that provides a built-in inclinometer and look up data tables.

13. The system of claim 12 , wherein the look up data tables display a correct locking nut drive up angle based on a bearing type inputted into the smartphone.

14. The system of claim 13 , wherein when a force is applied to an outer end of the lever arm and the hookspanner wrench begins to rotate the locking nut, and wherein the inclinometer responds in real time and displays an updated locking nut drive up angle position.

15. The system of c
