Product Description Product DescriptionSPROCKETSSprockets and links, also known in the industry as gears, run between the links of an excavator or bulldozer chain. Additionally, this undercarriage component runs on bushings that connect the two links of the chain. The gears are mounted around the machine's drive gear and are only used to drive the chain, so they do not bear any of the machine's weight.Sprockets are first molded or forged and then machined, which gives them a special heat treatment. If the steel does not contain enough carbon, it will become brittle during the hardening process. If it is only surface hardened, the sprocket or link will wear very quickly over time. Therefore, the sprocket teeth are hardened by induction hardening. The links are precision forged, finished, and hardened under special conditions.* We specialize in producing high-quality excavator and bulldozer Rim. * High-quality alloy steel is used, and the forging is replaced by the rolling ring forging process to ensure the continuity of the metal fiber structure. * So that the fiber structure of the forging is consistent with the shape of the forging, The metal flow line is complete, ensuring that the parts have good mechanical properties and longer service life.THE ROLE OF THE EXCAVATOR SPROCKETThe sprocket is bolted to the final drive and transmits the torque generated by the reduction gear system to the rubber track.The sprocket teeth mesh with the rubber track steel inserts, pushing the rubber track, which interacts with the ground through friction, grip, or both, trying to push the ground.Under favorable conditions, according to Newton's third law, the ground will react with an equal and opposite force, pushing the chassis.Product ParametersSPROCKET SPECIFICATIONSProduct NameSprocketKeywordsExcavator Drive SprocketMaterial40MnB/35MnBFinishSmoothColorsAs per to customer's requestTechniqueForging &castingWeight10-50kgSurface HardnessHRC50-56,Deepth:4mm-10mmSizestandard or CustomizedProcessForging CastingTest ReportProvidedShapeRoundQuality100% TestedOEMOEM Services ProvidedMOQ1 PieceSupport customization of idler pulleys of various specifications and usesParameAMPHWN-φZCodeDH55/R60250465135421812-φ1721DH1303255921715618.715-φ17.521DH1703626451716421.621-φ1823DH370490740216903328-φ2121DH400490740216903328-φ2121DH220/R225-7402660190681830-φ1621DH2804507602037425.516-021.523DH4503255901715222.415-φ1721E552304241354914.59-φ15.519E70B265555135381812-φ1625E70B-3288555135381712-φ1625E120B346600171.5522115-φ1821E200B4156601906322.314-φ21.521E305.5B230428135491612-φ1519E320456660190652316-φ2121E325450697203752718-φ21.521E33051581321680.52816-φ21.523E345577810216862320-φ2523E450561885216862624-φ2725E300B450770190702516-φ2125 ParamdAMPHWN-lZCodeEC140366591171.5581622-φ1721EC150320650171.1561520-φ1823EC2404106581906221.418-φ1921EC290450704203842816-φ2121EC360450760216902724-φ2121EC460/R450461B19216872624-φ2123EX30-52043501012814.69-φ1321EX3521035010127159-φ1321EX552304201354212.39-φ1519EX60-1290535154501812-φ1721EX703305351544019.612-φ1823EX903305351544019.612-φ1821EX1003565901715821.716-φ1721EX136370591171561616-φ1821EX150-1/EX150365643171651722-φ1723EX200-14156571756321.616-φ2223EX200-24306581907020.816-φ21.521EX200-3419658190702416-φ2221EX300-3465704203902820-φ2221UH04-7268600171.5641616-φ1821UH045284600171671916-φ1921UH025-52455351545014121-φ1821UH025-724553454491612-φ1721UH0633306551716618.516-φ17.523UH0812766651756522.314-φ21.521UH083370660175702316-φ2223HD307265514135381812-φ17.523HD550-33626501716422.715-017.523HD550-73626501716422.721-φ1823HD700-2362590171602115-φ17.521HD1880556B21216902824-φ2523HD8004026601906221.322-φ1821MS120-23806451715B2016-φ1823MS110-B/MS1102405061353818.516-φ1323TB175250530154361612-φ1621PC2019038010127159-φ1323PC301903501012714.59-φ1321PC30-72103851012515.69-φ1323PC30-10210385101271412-φ1323PC40-721042013536169-φ1321PC60-6/7265525154361512-φ1621PC75265480154361512-φ15.519PC903245381754016.215-φ1919PC120-64006001754214.415-φ1821PC1504246601906021.615-φ1821PC200-134666019068176-φ6021PC200-5473660190731820-φ1921PC200-5473660175681920-φ1923 Detailed PhotosFORGING OF SPROCKETSAfter a professional quenching and tempering process, the sprockets and tooth blocks are guaranteed to have good mechanical properties, high strength, good wear resistance, and not easy to bend and break.Adopting advanced machining centers and vertical CNC lathes for production, high precision requirements, and strict quality management to ensure efficient and stable products.Quenching depth: root teeth 6-10mm, top teeth 18-23mm.SPROCKET DESIGN* The excavator sprocket can be installed at the back or front of the crawler chassis. Generally speaking, the crawler chassis is at the back, which can reduce the length of the driving part and reduce power loss.* But with the increase of speed, as the crawler vibrates and the belt jumps and loses more energy, the power loss of the rear sprocket becomes larger, so it is generally believed that the driving speed is less than 15-20 km/h, which is good for the rear sprocket. The crawler loader adopts the rear positioning method of the driving wheel.SPROCKET TOOTH PROFILE REQUIREMENTS:(1) Allow track pins to enter and exit meshing smoothly and reduce impact force on contact surfaces.(2) Tooth surface contact stress reduces friction.(3) When track spacing increases due to wear, track pins and sprocket teeth can still work without chaining off.SPROCKET CHARACTERISTICS* An excavator drive sprocket is essential for transferring power from the final drive to the track chain, ensuring smooth and efficient machine operation.* Built for durability, it engages precisely with the track links to minimize wear and extend undercarriage life.ADVANTAGES OF CHOOSING OUR LOWER ROLLERS1.
