A gearbox is a power transmission device to produce high torque by reducing the drive speed or increase the drive speed the other way. Planetary gearbox consisting three components: sun gear, planet gear and ring gear .A Sun gear is a gearwheel in a planetary gear system, that rotates around its own axis and has other gears (planet gears) that rotate around it. Much like the Sun and planets in our solar system. The amount of planetary gears in a gearbox varies based on the gear ratio. Most planetary gearboxes have from two to five planet gears.When looking at planetary gears, the strength of the gearbox is usually determined by the size of the sun gear. Larger sun gears will allow for higher torque values.The planet carrier,Its objective is to hold up to gears of the same size, which mesh with the sun gear. Planetary Gearbox advantages:Provides high torque at slow speeds .The shafts are made up of hardened and tempered alloy steel . Sun gears ,planet gears and ring gears are made of powder metallurgy and sintering steel Low noise levels.Good quality taper roller bearings for input and output shafts .High efficiency .We produce precision metal gearboxes through powder metallurgy .Powder metallurgy is ametal workingprocess in which finely-powdered metal is mixed with binder material to create a"feedstock" that is then shaped and solidified usinginjection molding.The ability to combine several operations into one process ensures MIM is successful in saving lead times as well as costs, providing significant benefits to manufacturers. The metal injection molding process might be a green technology due to the significant reduction in wastage compared to "traditional" manufacturing methods.MIM can produce parts where it is difficult, or even impossible, to efficiently manufacture an item through other means of fabrication. Increased costs for traditional manufacturing methods inherent to part complexity, such as internal/external threads, miniaturization, or identity marking, typically do not increase the cost in a MIM operation due to the flexibility of injection molding.The window of economic advantage in metal injection molded parts lies in complexity and volume for small-size parts. MIM materials are comparable to metal formed by competing methods, and final products are used in a broad range of industrial, commercial, medical, dental, firearms,aerospace, andautomotiveapplications. Dimensional tolerances of ±0.3% are common and machining is required for closer tolerances . MIM technology has found increased applications in the commercial world - from home appliances to watches, automobiles to aerospace, and medical to orthodontics.The advantages of metal injection molding for metal fabrications :Highest degree of design freedom for complex shapes and geometriesProvides practical economic solutions to increasingly stringent material and product design requirementsFunctional integration of various features, such as lateral drillings, interior and exterior threads and gear teeth.Components can be heat and surface treated, plated, welded and solderedVery high volume production series run on fully-automatic injection molding machines using multi-cavity toolsmetal injection moulding process custom metal partsMIM prcess in each steps :1. metal powers option2.
