TRANSMISSION GEARTransmission gears for buses and trucks manufactured by 3,500 ton and 4,500 ton presses.
Product description Transmission gears used for heavy trucks or buses. Production equipment Produced by large-size press (3,500 ton and 4,500 ton equipment). Scope of work Scope of work can be performed up to outer flange diameters of ø320 mm and the rib part is formed thin and wide, causing overload to the machine. Therefore, a safety factor should be considered when designing. Technical characteristics Because many quality problems occur at the Rib joint part, caution is required in designing. To reduce weight and standard operation time, this product is produced by inserting a hole in the Rip part.
DRIVE PINIONA product that transmits power to the axle. There are two types (A and B), depending on the shape of the head part.
Product description Drive pinions used for the differential that drives both wheels by changing the rotational direction of the torque transmitted from the car’s transmission. (They rotate by engaging with the ring gear) Technical characteristics Minimum deformation occurs in the gear teeth part at the time of carburization after machining only when the flow-line is formed perpendicular to the surface. Therefore, the flow-line is improved by setting the standard of the raw material specification and depressed area specification.
RING GEARA product that changes the direction of rotational force transmitted from the transmission to drive both wheels.
Product description Ring gears that change the direction of rotational force transmitted from the transmission to drive both wheels. (It rotates by engaging with the drive pinion.) Technical characteristics Products that are thin compared with the outer diameter due to the product’s shape. The product should be designed in consideration of the safety factor of the machine so that overload is not applied to the machine due to a forging load that is larger than the theoretical load.
AXLE SHAFTA rear axle shaft used for vehicles and agricultural machinery produced by the 5 inch or 7.5 inch upsetter.
Product description Rear axle shaft used for vehicles and agricultural machinery. Production equipment Produced by the upsetter (forging equipment dedicated for the shaft). 5 inch upsetter and 7.5 inch upsetter are available. Scope of work Producing a flange outer diameter of Ø210 mm, shaft diameter of Ø70 mm, and a product of up to 40 kg. Technical characteristics The product was produced by welding the shaft and flange in the past. Now, the product is manufactured in a single piece using upsetter equipment, saving welding costs and improving strength.
BEVEL GEARGears used for the device that distributes the proper rotational speed required for both wheels when driving on a curve.
Product description Gears used for the device that distributes the proper rotational speed required for both wheels when driving on the curve. Technical characteristics Forging/Machining costs are minimized by inserting the tooth shape into the shape of the product.
YOKEA propeller shaft part that transmits the torque of the transmission to the axle.
Product description Yokes are propeller shaft parts that transmit the torque of the transmission to the axle. Production equipment The product shape makes molding difficult, and complicated flash shapes appear. Scope of work Production equipment is determined by the size of the product. The above product is produced by a 2,500 ton press. Technical characteristics A product that is susceptible to quality problems such as underfill and material overlapping. Blocker mold design is important, and the materials should be placed on the horn part of both sides when forging.
