Abstract

A system for measuring angle adjustment of a hookspanner wrench to accurately tighten a bearing onto a shaft, the shaft having an adapter sleeve mounted thereon, the adapter sleeve 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.

First claim

The invention claimed is:

1. A device for measuring angle adjustment of a hookspanner wrench to accurately tighten a bearing onto a shaft having an adapter sleeve, the device comprising:
a hookspanner wrench having a lever arm and an engaging portion, the engaging portion 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, the built-in inclinometer displaying:
a first color when the hookspanner wrench is in a first position;
a second color when the hookspanner wrench in between the first position and a second position; and
a third color when the hookspanner wrench is in the second position.

2. The device 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 device 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 locknut drive up angle position.

4. The device 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 device 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 device 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 obtained.

7. The device 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 device for measuring angle adjustment of a hookspanner wrench to accurately tighten a bearing onto a shaft having an adapter sleeve, the device comprising:
a hookspanner wrench having a lever arm and an engaging portion, the engaging portion 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, wherein a specialized application stored on the smartphone that provides the built-in inclinometer and look up data tables provides a traffic light concept to indicate the mounting angle/drive up position obtained by displaying a green light for continuing to tighten the hookspanner wrench, a yellow lamp for when getting close to the pre-programmed angle, and a red lamp for stopping at the pre-programmed angle.

9. A system for measuring angle adjustment of a hookspanner wrench to accurately tighten a bearing onto a shaft having an adapter sleeve mounted thereon, the adapter sleeve having a threaded portion and a 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, 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, the built-in inclinometer displaying:
a first color when the hookspanner wrench is in a first position;
a second color when the hookspanner wrench in between the first position and a second position; and
a third color when the hookspanner wrench is in the second position,

the bearing having an inner race, the inner race having a tapered bore, the bearing being slid onto a tapered portion of the adapter sleeve,
the bearing locking nut having a threaded inner portion and screwed onto a threaded portion of the adapter sleeve, the bearing locking nut being screwed onto the threaded portion of the adapter sleeve until an inner side of the locking nut and an outer side of the bearing inner race just start to 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 locking 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.

10. The system for measuring angle adjustment of a hookspanner wrench to accurately secure a bearing onto a shaft having an adapter sleeve mounted thereon according to claim 9 , 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.
