The detailed parameters of the R138-V30-6P-27.86-M1 reducer are as follows:
This model belongs to the R series horizontal hard tooth surface helical gear reducer, which is suitable for medium and high power transmission scenarios and has high load-bearing capacity and transmission efficiency. According to existing technical data, its core parameters can be analyzed as follows:
1. Model Analysis
R138: Indicates the reducer with frame number 138 in the R series. It is a large model and is suitable for heavy-load conditions.
V30: Usually represents the input connection form, V-shaped pulley or specific motor adapter interface. Some manufacturers use V to indicate compact structure, which needs to be confirmed with the specific brand.
6P: refers to the 6-pole motor (synchronous speed is about 1000 rpm), which is used in low-speed and high-torque output situations.
27.86: The transmission ratio is 27.86, that is, the input shaft rotates 27.86 times and the output shaft rotates 1 circle, which is suitable for equipment that requires significant speed reduction.
M1: Installation form code, M1 generally means horizontal foot installation, output shaft downward or standard direction layout, please refer to the manufacturer"s drawings for details.
2, performance parameters (refer to the same series for calculation)
Input power: about 5.5 kW (based on common configuration of R138 series)
Output speed: about 32 rpm (calculated based on 6-pole motor 960 rpm ÷ 27.86)
Output torque: up to 6290 N·m (similar to R138-B5.5KW model)
Safety factor: Generally 1.25, meeting general industrial safety requirements
Transmission efficiency: ≥96%, thanks to three-stage helical gear design and precision machining
3. Structure and installation
