Abstract
A method for spin set bearing setting verification in a preload state on a shaft. An inertia wheel may be disposed on the shaft. The inertia wheel or the shaft is rotated. A first rotational speed is measured at a first time. The inertia wheel may decelerate over time to achieve a second rotational speed measured at a second time. The second speed is less than first speed. The change in time between the first time and the second time is measured. The bearing setting may be adjusted if the change in time is outside a predetermined time range. The bearing setting may remain unchanged if the change in time is within a predetermined time range.
Claims18
A method for setting bearings comprising the steps of:
- setting a bearing set on a shaft;
- positioning an inertia wheel on the shaft;
- rotating the inertia wheel;
- measuring a first time value at a first rotational speed;
- measuring a second time value at a second rotational speed, the second rotational speed being less than the first rotational speed;
- measuring a change in rotational speed between the first time value and the second time value;
- and
- adjusting the bearing setting if the change in rotational speed is outside a predetermined rotational speed range.
A method for setting bearings comprising the steps of:
- setting a bearing set on a shaft of a transmission for an agricultural tractor;
- positioning an inertia wheel on the shaft;
- rotating the inertia wheel;
- measuring a first time value at a first rotational speed;
- measuring a second time value at a second rotational speed, the second rotational speed being less than the first rotational speed;
- adjusting the bearing setting if the change in rotational speed is outside a predetermined rotational speed range, the predetermined rotational speed range having an upper limit and a lower limit, wherein if the change in rotational speed is above the upper limit the bearing set is in end play, if the change in rotational speed is within the predetermined rotational speed range, the bearing set is in appropriate preload, and if the change in rotational speed is below the lower limit, the bearing set is too tight.
