Abstract
A work machine includes a compactor drum, a controller, and an output device. The compactor drum includes a vibratory system, which includes at least one bearing that supports rotation of the vibratory system within the compactor drum, and lubricant received by the at least one bearing. The controller is configured to monitor at least one physical property of the vibratory system over a specified time and project a remaining useful life of the lubricant based on the at least one physical property. The output device is configured to generate an output indicative of the remaining useful life.
Claims20
A work machine comprising:
- a compactor drum that comprises a vibratory system, the vibratory system comprising:
- at least one bearing that supports rotation of the vibratory system within the compactor drum;
- and
- lubricant received by the at least one bearing;
- a controller configured to monitor a plurality of physical properties of the vibratory system over a specified time and project a remaining useful life of the lubricant based on the plurality of physical properties;
- and
- an output device configured to generate an output indicative of the remaining useful life.
A method of estimating a remaining useful life of a lubricant for a vibratory system of a compaction machine, the method comprising:
- receiving, by at least one bearing of the vibratory system, a lubricant;
- monitoring, by a controller, a plurality of physical properties of the vibratory system over a specified time;
- projecting, by the controller, a remaining useful life of the lubricant based on the a plurality of physical properties of the vibratory system over the specified time;
- and
- outputting an indication of the remaining useful life of the lubricant for an operator of the vibratory system.
A vibratory compactor that includes a compactor drum, the vibratory compactor comprising:
- a vibratory system positioned within the compactor drum, the vibratory system comprising:
- at least one bearing that supports rotation of the vibratory system within the compactor drum;
- and
- lubricant received by the at least one bearing;
- a controller configured to monitor a plurality of physical properties of the vibratory system and project a remaining useful life of the lubricant based on the plurality of physical properties;
- and
- an output device configured to generate an output indicative of the remaining useful life.
