Product Overview:

ZSY250 is a ‌three-stage hardened cylindrical gear reducer‌, complying with the JB/T8853 standard. Its core parameters vary with the nominal transmission ratio, and the key data are summarized as follows:

Core Specification Parameters

• ‌Model Meaning‌: Z (Cylindrical), S(Three-stage), Y (Hardened Tooth Surface).
• ‌Input Speed‌: Usually ≤1500 r/min (also adaptable to 1000/750 r/min).
• ‌Tooth Surface Hardness‌: HRC 54-62 (carburizing and quenching process).
• ‌Transmission Efficiency‌: Three-stage transmission efficiency >85%.
• ‌Applicable Environment‌: Temperature -40℃~45℃, circumferential speed ≤20 m/s.

Typical Operating Condition Parameters (Input Speed 1500 r/min)

Note: If the input speed is 1000 r/min, the power needs to be converted proportionally (about 65%-70% of the value at 1500 r/min).
