Latest Patents

Among his latest patents is an aerial spinning toy, which demonstrates his creativity in recreational inventions. Additionally, he developed a water lubricated bearing assembly for mining machines. This innovative bearing assembly for a rotary drilling tool includes inner and outer races with annular bearing surfaces and an annular channel formed between the races for water lubrication and cooling of roller bearing members positioned within the channel. A pump supplies pressurized flow through the channel, ensuring lubrication and preventing the feedback of rock particles. The design also features a transfer passageway that drains water from the bearing assembly, cooling the cutter teeth and reducing fine respirable dust, which poses a health hazard to mine workers. The rollers of the bearing include an annular notch that forms part of the flow channel, occupying approximately fifteen percent of the cross-sectional area. An elastic ring support for the outer race absorbs a significant portion of the drilling stress from the tool. Rotary water seals and wipers beside the bearings create a rotary water-tight joint, maintaining the concentric position of the fixed and rotary elements of the seals and wipers.
