A smart axle for track rollers or idlers

Abstract

The present invention provides an intelligent shaft for a thrust wheel or a guide wheel. The intelligent shaft comprises a hollow shaft body and two end heads; a central oil groove between the two end heads is formed in the inner hole of the hollow shaft body; oil holes are formed in the hollow shaft body; and an oil injection hole is formed in one of the two end heads, and the other end head is provided with a temperature sensor and a lubricant concentration sensor, or both of the two end heads are provided with a temperature sensor and a lubricant concentration sensor. According to the intelligent shaft for the thrust wheel or the guide wheel of the invention, the central oil groove is formed on the basis of the inner hole of the hollow shaft body, the oil injection hole is formed in one of the two end heads, and therefore, the number of oil grooves or oil storage cavities required to be machined on the other components of the thrust wheel or guide wheel can be decreased, and the machining costs of the thrust wheel or guide wheel can be low; and the temperature sensor and the lubricant concentration sensor are adopted, the quality of lubricant can be monitored in real time, and therefore, it can be ensured that the service life of the thrust wheel or guide wheel will be long, and the lubricant will not be wasted.

Description

technical field [0001] The invention relates to a mechanical component, in particular a smart axle for a roller or guide wheel. Background technique [0002] With the continuous development of society, large-scale infrastructure projects are constantly being implemented. In infrastructure projects, it is inevitable to use engineering vehicles such as excavators and bulldozers. The walking mechanism of such engineering vehicles usually requires the use of guide wheels and supporting weights. wheel. [0003] Lubrication is required between the wheel body and the supporting shaft of the guide wheel or supporting wheel, so the existing guiding wheel or supporting wheel all need to provide oil holes and oil storage tanks on the wheel body and the supporting shaft, as the announcement number is CN203946186U A track roller disclosed in a Chinese utility model patent includes a track roller body, a support shaft, and a karaoke. A floating seal ring and a floating seal rubber ring a...

AI Technical Summary

Problems solved by technology

The track roller not only needs to set up lubricating oil passages on the support shaft, but also needs to set up oil grooves and oil storage chambers on other components to avoid wear and improve the service life of the track rollers, but it also makes the track rollers such as the support shaft zero. The processing of components is complicated and the processing cost is relatively high

[0004] In addition, lubricating oil will deteriorate after long-term use, and it needs to be changed in time, otherwise it will affect the lubrication effect. Can be replaced regularly, if the replacement cycle is too long, it may cause wear between the wheel body and the support shaft, affecting the service life of the guide wheel or roller; if the replacement cycle is too short, it will cause waste of lubricating oil
