ZLYJ序REDUCER特别是PLASTC EXTRUDIN

The ZLYJ series gear reducer is specially working for the plastic extruding machines. ZLYJ series speed reducer is a transmission part that possesses high precision hard gear surface and thrust block designed for plastic screw extruder. The design of product adapts all kinds of norm specified in ZBJ19009-88/ it features that gear and axis parts are made of high strength alloy steel. The gear is processes by carburization, quenching and tooth grinding process. The precision of gear is grade 6 specified in GB10095-88. The hardness of gear surface is HRC54 62. At front end of hollow input axis there is large specification thrust bearing that will bear axial thrust force while the screw is working. The complete machine features compact, high in bearing capacity, stable in transmission, low noise, high efficiency, etc. Hold series code name , specification number , transmission ratio , assemble a pattern in the machine reducing the speed in the type. Mark gives a demonstration. The nominal velocity ratio of series code name specification number assembles the machine reducing the speed pattern. 1. The gears and the gear shafts of this kind of gear reducer are finished with gas carburising process and precise grounding to sequentially get high loading capacity of per certain volume. 2. The strength of the hard tooth surface can reach to HRC-54-62. 3. All key components are finished by precisely machine, accurate assembly, and finally tested, and therefore, fairly low noise is reached. 4. The efficiency of gear unit can reach 95%, and has a long service life.
