Designed specifically for cranes, it plays a vital role in various crane mechanisms. Furthermore, it is well-suited for other types of machinery, such as transportation systems, metallurgy equipment, mining operations, chemical processing units, and light industrial tools, where reliable power transmission is crucial.<\/p>\n<h3>Features<\/h3>\n<ul>\n<li><strong>Materials:<\/strong><br \/>\nEngineers utilize high-quality, low-carbon alloy steel to craft the gears. After carburizing and quenching, these gears achieve a remarkable accuracy grade of 6.<\/li>\n<li><strong>Performance:<\/strong><br \/>\nThe gearbox delivers several advantages, including high precision, exceptional efficiency, smooth transmission, and reduced noise levels. Compared to the QJ series tempered gearbox, it surpasses its predecessor with a more compact size, lighter weight, higher load capacity, and enhanced reliability.<\/li>\n<li><strong>Structure:<\/strong><br \/>\nThe design incorporates a welded housing, providing robustness and durability. Additionally, the structure supports both three-point mounting and base mounting options, ensuring flexibility.<\/li>\n<li><strong>Output Shaft Types:<\/strong><br \/>\nThe QJY Reducer offers four output shaft configurations: flat key, involute spline, gear shaft end, and hollow shaft, catering to diverse application needs.<\/li>\n<li><strong>Lubrication and Cooling:<\/strong><br \/>\nFor lubrication, manufacturers typically use an oil sump system paired with natural cooling. However, for vertical gearboxes, they adopt a circulating oil lubrication system. Additionally, the reducer employs rolling bearings to enhance performance.<\/li>\n<\/ul>\n<h3>Operating Conditions<\/h3>\n<ul>\n<li><strong>Input Speed:<\/strong><br \/>\nThe gearbox operates effectively at input speeds below 1500 r\/min.<\/li>\n<li><strong>Temperature Range:<\/strong><br \/>\nWith a wide operational range, it functions reliably in temperatures between -40\u00b0C and +50\u00b0C.<\/li>\n<li><strong>Directional Operation:<\/strong><br \/>\nIts ability to perform bi-directional operation increases adaptability across various crane gearbox types.<\/li>\n<li><strong>Mounting Options:<\/strong><br \/>\nThe QJY Reducer provides multiple assembly configurations, offering versatile solutions for a variety of applications.<\/li>\n<\/ul>\n<h6><span style=\"font-size: 18pt;\"><strong><span style=\"font-family: arial, helvetica, sans-serif;\">Assembly form<\/span><\/strong><\/span><\/h6>\n<p><img
