Herringbone Gear Reducer最先出現在DEZHOU L&A PETROLEUM MACHINERY CO.,LTD。
]]>The gear and gear reducer produced by our company utilize Lufkin herringbone gear technology. Gear processing is performed with specialized gear equipment, featuring a left and right helix angle of 30o. The diameter is controlled using specialized tools and an expansion method. Due to the characteristics of gear planing, our herringbone gears benefit from balanced forces, no axial force, and enhanced load-bearing capacity, resulting in a longer lifespan.
The reducer casing and cover undergo annealing before processing, which reduces casting stress by 90%. This ensures that the joint surfaces can be disassembled without deformation.
Product Line：
1.LUFKIN 80D, 114D, 160D, 228D, 320D, 456D, 640D, 912D 1280D pumping unit reducer and gear;
2.AMERICAN D114G, D 160G, D 228, 320F, 456F, D 640F, D912G pumping unit reducer and gear.。
Reducer products are strictly controlled according to API 11E standards
? Horizontal split cover gear housing design, easy to maintain on site.
? Precisely machined herringbone gear, uniform force, strong bearing capacity, longer life.
? All shafts are made of alloy steel, heat treated and precision machined to tight tolerances.
? Large brass sleeve on low speed shaft with high accuracy and long life. (LUFKIN)
? Integrated forced lubrication system, stable and reliable.
? Oil scraping components are installed from the upper part of the driving wheel, and the structural force is better than the lubricating effect.
? All parts are fully interchangeable with the LUFKIN and American gearbox.
