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.
Claims10
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.
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.
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.
