Can you provide detailed parameters of R138-V30-6P-S7.86-M1 reducer

The detailed parameters of R138-V30-6P-S7.86-M1 reducer are as follows:

This model belongs to the R series horizontal hard tooth helical gear reducer, suitable for medium to high power transmission scenarios, with high load-bearing capacity and transmission efficiency. According to existing technical data, its core parameters can be analyzed as follows:

1. Model analysis

R138: Refers to the gearbox with seat number 138 in the R series, which is a large specification and suitable for heavy-duty conditions.

V30: usually represents the input connection form, V-belt pulley or specific motor adaptation interface. Some manufacturers use V to represent compact structure, which needs to be confirmed with specific brands.

6P: Refers to a 6-pole motor (synchronous speed of about 1000 rpm) that is suitable for low-speed and high torque output applications.

27.86: The transmission ratio is 27.86, which means the input shaft rotates 27.86 turns and the output shaft rotates 1 turn, making it suitable for equipment that requires significant speed reduction.

M1: Installation form code, M1 generally refers to horizontal foot installation, output shaft facing downwards or standard direction layout, specific to the manufacturer's drawings.

2. Performance parameters (based on calculations from the same series)

Input power: approximately 5.5 kW (based on common configurations of R138 series)

Output speed: approximately 32 rpm (calculated as 960 rpm ÷ 27.86 for a 6-pole motor)

Output torque: up to 6290 N · m (similar to R138-B5.5KW models)

Safety factor: generally 1.25, meeting general industrial safety requirements

Transmission efficiency: ≥ 96%, thanks to the three-stage helical gear design and precision machining

3. Structure and Installation

Transmission structure: three-stage helical gear transmission, smooth operation, low noise

Box material: HT250 gray cast iron, high strength and good vibration resistance

Lubrication method: Built in splash lubrication system, easy to maintain

Protection level: IP55, dustproof and waterproof, suitable for factory workshop environment

Output shaft size: Φ 20mm+keyway 2.5mm (customizable), total length 174mm, width 135mm, height 134mm (including output shaft)

4. Adaptation and Application
This model is commonly used in industrial systems that require high stability, such as conveying equipment, mixing machinery, and lifting devices, especially suitable for continuous operation and conditions with large load fluctuations.
