Product Description OEM Customer custom forging Large Module pinion gear Sugar Mill Large Crown tooth Gear WheelProduct DescriptionGear transmission relies on the thrust between gear teeth to transmit motion and power, also known as meshing transmission. With this gradual meshing, helical gears operate much more smoothly and quietly than spur gears. Therefore, almost all automobile transmissions use helical gears.Since the teeth on the helical gear present a certain angle, the gears will be under a certain amount of stress when they mesh. Equipment using helical gears is equipped with bearings to withstand this pressure. The precision of gear grinding precision gear can reach 5~6 levels. The corresponding dimensional accuracy can be achieved through precision gear grinding machine and grinder. It has the characteristics of stable transmission, low noise, long service life, and is suitable for high-power and heavy load. Spur GearGears having cylindrical pitch surfaces are called cylindrical gears. Spur gears belong to the parallel shaft gear group and are cylindrical gears with a tooth line which is straight and parallel to the shaft. Spur gears are the most widely used gears that can achieve high accuracy with relatively easy production processes. They have the characteristic of having no load in the axial direction (thrust load). The larger of the meshing pair is called the gear and smaller is called the pinion. Helical GearHelical gears are used with parallel shafts similar to spur gears and are cylindrical gears with winding tooth lines. They have better teeth meshing than spur gears and have superior quietness and can transmit higher loads, making them suitable for high speed applications. When using helical gears, they create thrust force in the axial direction, necessitating the use of thrust bearings. Helical gears come with right hand and left hand twist requiring opposite hand gears for a meshing pair.Gear RackSame sized and shaped teeth cut at equal distances along a flat surface or a straight rod is called a gear rack. A gear rack is a cylindrical gear with the radius of the pitch cylinder being infinite. By meshing with a cylindrical gear pinion, it converts rotational motion into linear motion. Gear racks can be broadly divided into straight tooth racks and helical tooth racks, but both have straight tooth lines. By machining the ends of gear racks, it is possible to connect gear racks end to end. Bevel GearBevel gears have a cone shaped appearance and are used to transmit force between two shafts which intersect at one point (intersecting shafts). A bevel gear has a cone as its pitch surface and its teeth are cut along the cone. Kinds of bevel gears include straight bevel gears, helical bevel gears, spiral bevel gears, miter gears, angular bevel gears, crown gears, zerol bevel gears and hypoid gears. Screw GearScrew gears are a pair of same hand helical gears with the twist angle of 45° on non-parallel, non-intersecting shafts. Because the tooth contact is a point, their load carrying capacity is low and they are not suitable for large power transmission. Since power is transmitted by the sliding of the tooth surfaces, it is necessary to pay attention to lubrication when using screw gears. Worm GearA screw shape cut on a shaft is the worm, the mating gear is the worm wheel, and together on non-intersecting shafts is called a worm gear. Worms and worm wheels are not limited to cylindrical shapes. There is the hour-glass type which can increase the contact ratio, but production becomes more difficult. Due to the sliding contact of the gear surfaces, it is necessary to reduce friction. For this reason, generally a hard material is used for the worm, and a soft material is used for worm wheel. Even though the efficiency is low due to the sliding contact, the rotation is smooth and quiet. When the lead angle of the worm is small, it creates a self-locking feature. Internal gearInternal gears have teeth cut on the inside of cylinders or cones and are paired with external gears. The main use of internal gears are for planetary gear drives and gear type shaft couplings. There are limitations in the number of teeth differences between internal and external gears due to involute interference, trochoid interference and trimming problems. The rotational directions of the internal and external gears in mesh are the same while they are opposite when two external gears are in mesh.Product Parameters Product nameSpur Gear & Helical Gear & Gear ShaftMaterials AvailableStainless Steel, Carbon Steel, Brass, Bronze, Iron, Aluminum Alloy etcHeat TreatmentQuenching & Tempering, Carburizing & Quenching, High-frequency Hardening, Carbonitriding......Surface TreatmentCarburizing and Quenching,Tempering ,Tooth suface high quenching Hardening,TemperingBOREFinished bore, Pilot Bore, Special requestProcessing MethodMolding, Shaving, Hobbing, Drilling, Tapping, Reaming, Manual Chamfering, Grinding etcPressure Angle20 DegreeHardness55- 60HRCSizeCustomer Drawings & ISO standardPackageWooden Case/Container and pallet, or made-to-orderCertificateISO9001:2008Machining ProcessGear Hobbing, Gear Milling, Gear Shaping, Gear Broaching, Gear Shaving, Gear Grinding and Gear LappingApplicationsToy, Automotive, instrument, electrical equipment, household appliances, furniture, mechanical equipment,daily living equipment,electronic sports equipment, , sanitation machinery, market/ hotel equipment supplies, etc.Advantages1.
