Product DescriptionCustom GearboxUsually we produce large gearboxes according to drawings. Large gearboxes are widely used. We can produce two-stage gearboxes, three-stage gearboxes or other large gearboxes. Our accuracy can reach 6 levels. We can provide complete inspection reports and support third-party inspection/online video inspection/factory inspection.Customized heavy-duty gearbox/high-speed gear reducer includes reducer case/body/housing, transmission spare parts such as gears, gear shafts, bearings, washers and other spare parts.Typical processing flow of the main components of the reducer (such as housing, gears, etc.):Reducer housing processing1. Raw material preparation: Cast iron or steel is usually used as raw material, and cutting is performed according to the design drawings.2. Casting/welding: For large reducer housings, casting is generally used for molding; for some small housings with high strength requirements, forging may be selected.3. Rough machining: Preliminary machining of castings or forgings, including turning, milling and other processes, to remove excess material and form a rough outline.4. Heat treatment: In order to improve the hardness and wear resistance of the housing, heat treatment operations such as normalizing and tempering are sometimes required.5. Finishing: Use precision machine tools to complete the fine machining of key parts such as bearing holes and mounting surfaces to ensure that the dimensional accuracy and surface finish meet the requirements.6. Inspection: Use tools such as three-coordinate measuring instruments to check whether the processed parts meet the design specifications.Gear processing1. Blank manufacturing: Select the appropriate material according to the design parameters of the gear and make it into a blank form. This step may involve forging or bar cutting.2. Tooth profile rough machining: Use a hobbing machine or a gear shaping machine to perform preliminary tooth profile machining on the gear blank.3. Heat treatment: The gears are carburized and quenched or other appropriate heat treatment methods are used to enhance the hardness and overall strength of the tooth surface.4. Tooth profile finishing: After heat treatment, the gears need to be ground and shaved again to ensure that the tooth profile accuracy meets the design standards.5. Surface treatment: In order to improve corrosion resistance and aesthetics, the gear surface can be galvanized, phosphated, etc.Other component processingShaft parts: The shaft is usually directly processed from forging blank, including turning, grinding and other steps.Seals and other accessories: Customized production according to specific needs to ensure compatibility with the entire system.Assembly and testingAssembly: All processed parts are assembled into a complete reducer according to the assembly drawing.Debugging and testing: The assembled reducer is fully functionally tested, including no-load operation, load test, and noise detection, to ensure that its performance indicators meet the standards.Who We AreEstablished in 2002, Luoyang Wangli Heavy Machinery Co.,ltd. focus on metal research and mining machinery spare parts. Our factory located in Luoyang, one of important base for heavy machinery in China. 2 factories over an area of 13,300 square meters, based on 100+ sets of equipment, our production capacity reaches 12000 Tons/Year. has passed ISO 9001 quality managment system certification in 2015.Our mainly products: dragline excavator spare parts,rotary kiln spare parts, large modulus gear (gear shaft), gearbox ect. 40+ patents with over 45 years experience to help focus on improve the service life of spare parts. We belive that more than 80% reason of mechanical parts' working life depends on hot processing (steel making/forging/casting/welding/heat treatment). Eight material engineers will control the quality from the original resource. Over the past 15+ export experience, we have served 200+ compaies in 50+ countries and regions, During these times, three international key projects, such as segment girth gear used in the Suez Canal in Egypt.We believe that innovation is the key to success and attracts talents who can think differently. Together, we can make a real difference.About UsWe have different specifications of oil forging presses,ring rolling machines,electric arc furnaces,thus we can provide variety of forging,casting and welding materials according to customer's requests.We have the completed machining equipment,including horizontal lathe,vertical lathe,CNC boring and milling machine, CNC boring machine,deep hole drilling and boring machine,gear hobbing machine,gear teeth grinding machine,grinding machine, etc. Strictly quality inspection system can produce high quality products.For each order,we can provide report for material chemical components testing,UT testing,hardness,mechanical property testing(impact testing,yield strength testing,tensile strength testing),size inspection,etc.Advantage of our Heat Treatment:- Professional, specific furnace, single-minded -Vertical pit furnace,keep the temperature uniformity during heating,+/-1℃ -Small deformation,little oxide layer,reduce material cost - Different materials can be cooled at the best speed - Large capacity,completed variety of quenching medium: oil,water,salt water,water based mixture.Our & CustomerCertifications
