Vibration wheel for vibratory roller

Abstract

The invention discloses a vibration wheel for a vibratory roller. The vibration wheel comprises an outer ring, a center plate arranged inside the outer ring and an inner ring arranged in the middle of the center plate. A vibration shaft with an eccentric shaft is arranged in the inner ring, and the two ends of the vibration shaft are fixedly connected with the center plate through vibration bearings. A sealed oil storage cavity is formed among the outer ring, the inner ring and the centre plate. A plurality of rib plates extending to the oil storage cavity are evenly distributed on the outer edge of the inner ring, and a supporting plate is arranged at the lower ends of the rib plates. According to the vibration wheel, lubricating oil can be kept within the best temperature range all the time, it is ensured that the lubricating oil is in the good working characteristics, and the service life of the vibration wheel is prolonged.

Description

technical field [0001] The invention relates to a vibration wheel for a vibratory road roller, belonging to the technical field of vibratory road rollers. Background technique [0002] The vibrating wheel of a traditional vibratory roller consists of an eccentric shaft, lubricating oil, inner ring, rib plate, left and right supporting plates, outer ring, coolant, web, vibration bearing and plug. When the eccentric shaft rotates, the centrifugal force will drive the entire steel wheel to vibrate. At the same time, the centrifugal force will generate a lot of heat when the vibration bearing rotates. Since the vibration wheel rolls, the web can bring lubricating oil into the vibration bearing to lubricate the vibration bearing. And the lubricating oil takes away the heat on the vibrating bearing and transmits it to the inner ring and the web while lubricating. [0003] The biggest defect of this structure is that the air convection between the inner ring and the outer ring is ...

AI Technical Summary

Problems solved by technology

[0003] The biggest defect of this structure is that the air convection between the inner ring and the outer ring is too slow, the heat transfer is limited, and the contact area between the web and the lubricating oil is too small, and the heat dissipation capacity is insufficient

This will easily lead to a higher temperature of the lubricating oil, resulting in a temperature exceeding the reasonable range of the lubricating oil, causing early failure of the lubricating oil, and reducing the life of the vibration bearing and premature damage
