1. 2 Material

1. Housing: Full range series using HT250 high strength cast iron, and made by lost-foam casting, so it improved the casting precision.

2 . Gears and output shaft: Al usinghigh-quality alloy steel forging blank, andosmotic quenching treatment, so it extended gears and output shaft’s effective life.

3 . Flat keys: C45, Surface hardness: HRC 50.

1. 3 Gear Unit Efficiency

1. High precision gear; seals; bearings;Effectively reduces friction; Stage efficiency of gear drive reaches 97%.

For some ways of mounting, the input gear is completely immersed in the lubricant, please consider the churning loss when it comes to big frame size and high input speed.

1. 4 Working Condition

1. Ambient temperature -40~ 50°C (if lower than O’C, need to heat the lubrication higher than O°C or use anti freezing lubricant).

2. Input rotation speed ≤ 2800r/min.

3 .

Both Rotation Direction.

4. No industry limit.

# 1.2 材料
1. 箱体：全系列采用 HT250 高强度铸铁，经消失模铸造工艺制成，有效提高了铸造精度。
2. 齿轮与输出轴：均采用优质合金钢锻打毛坯，并经渗碳淬火处理，延长了齿轮与输出轴的使用寿命。
3. 平键：材料 C45，表面硬度 HRC 50。

# 1.3 减速机效率
1. 高精度齿轮、密封件及轴承可有效降低摩擦，齿轮传动单级效率可达 97%。
部分安装方式下输入齿轮会完全浸入润滑油中，针对大机座型号与高输入转速工况，需考虑搅油损耗。

# 1.4 工作条件
1. 环境温度：-40～50℃（若低于 0℃，需将润滑油加热至 0℃以上或选用防冻润滑油）。
2. 输入转速 ≤ 2800 r/min。
3. 可双向旋转。
4. 无行业限制。
