The Z-series hard tooth surface cylindrical gear reducer is an external involute helical cylindrical gear reducer produced according to the JB/T8853-1999 standard. Its products include three series: single level (ZDY), double level (ZLY), and triple level (ZSY).

2、 Features:

1. The center distance, transmission ratio, and other factors have been optimized and designed, resulting in good interchangeability of major components and parts.

2. The gears are all made of high-quality alloy steel carburized and quenched, with a gear hardness of HRC58-62.

3. Small size, light weight, high accuracy, large load-bearing capacity, long service life, high reliability, smooth transmission, and low noise.

4. Generally, oil pool lubrication and natural cooling are used. When the thermal power cannot meet the requirements, circulating oil lubrication or fan and cooling coil can be used for cooling.

3、 Reducer model, specifications and their representation method:

1. The models include: ZDY single-stage cylindrical gear reducer, ZLY two-stage cylindrical gear reducer, and ZSY three-stage cylindrical gear reducer.

2. The specifications include: single level; 80, 100, 125, 160, 200, 250, 280, 315, 355, 400, 450, 500, 560;
