When selecting an oil-cooling or water-cooling system for the R27-15.63-0.25kW reducer, a comprehensive judgment must be made based on its power, speed, working environment and installation space. The air-cooled oil cooler is preferred. In high temperature, continuous operation or space-limited scenarios, a water-cooled plate cooler can be considered.
1. First clarify the basic parameters of the reducer (inferred based on the model)
R27-15.63-0.25kW is a small gear reducer with the following typical parameters:
Motor power: 0.25kW
Reduction ratio: 15.63
Output speed: about 90~100 r/min (assuming input speed 1400 r/min)
Output torque: about 24.5 N·m (calculation: T = 0.25 × 9550 ÷ 1400 × 15.63 × 0.9 ≈ 24.5 N·m)
This model is often used for small equipment with light load and continuous operation, such as conveyor lines, packaging machines, etc.
2. Oil cooling vs water cooling system selection suggestions
Conclusion : For a 0.25kW low-power reducer, the heat generation is small (estimated to be about 50~80W). Under normal working conditions, the air-cooled type is completely sufficient. If the equipment operates in a high temperature environment (>45°C) or continuously operates at full load, it can be upgraded to water cooling.
3. Selection Key parameter suggestions
1. Cooler type selection
Prefer air-cooled fin type or plate-fin type: compact structure, maintenance-free, and no risk of leakage
Water cooling optional plate type (removable): easy to clean, suitable for environments with good water quality
2. Matching cooling capacity
Estimation of system heat generation: According to the 'heating power estimation method', take 20%~35% of the motor power → PV = 0.25kW × 25% = 62.5W → Select a cooler with a cooling capacity ≥80W to leave a margin
3. Installation method optimization
It is recommended to adopt the independent circulation cooling method: install a cooling pump, pump oil from the fuel tank through the cooler and then return to the fuel tank to avoid damage to the cooler due to excessive return pressure.
The direction of the inlet and outlet of the cooler should be easy to connect. Vertical or horizontal installation can be selected according to the space.
4, material and lifespan
It is recommended to choose red copper finned tubes for heat transfer tubes, which are corrosion-resistant and have good thermal conductivity.
When the environment is dusty, install a protective net or fan filter
