introduction:Planetary reducer as Taixing city general reducer factory hot products,It has its own advantages,It is particularly prominent in terms of deceleration characteristics,Here is a brief introduction to the deceleration characteristics of the lower planet reducer: 1、High torque、Impact resistance:The mechanism of planetary gear is similar to the transmission mode of traditional parallel gear。Traditional gears only rely on the extrusion of very few contact surfaces between two gears,All the load is concentrated on the few gear faces in contact,Easy to produce friction and fracture between gears。The planetary gear reducer has six larger area contact surfaces with the gear360Degree uniform load,Multiple gear faces uniformly bear the instantaneous impact load,

introduction:Process and advantages of powder high speed steel There are two ways of making high speed steel,One is the traditional ingot casting,The other is made by powder metallurgy。Traditional smelting manufacturing is usually divided into secondary refining(EAF+LF+VD)Or electroslag remelting(ESR)Two kinds of process,The above method is due to slow cooling of the metal liquid,It will cause uneven segregation of alloy and coarse growth of alloy carbide,And affect the performance of high speed steel。Although subsequent hot work process,The casting structure of the ingot can be changed and refined,Reduce the adverse effects,But it does not eliminate the original casting tissue,Thus for physics and machinery
