What are the effects of the thickness and material of insulation cotton/insulation board on the insulation effect of the gearbox

The influence of the thickness and material of insulation cotton/insulation board on the insulation effect of the reducer is mainly reflected in the following aspects:
1. The influence of thickness on thermal insulation effect

Thermal insulation performance: Thicker insulation cotton can more effectively block heat transfer and reduce the impact of high temperature on surrounding components of the gearbox. For example, a thickness of around 10 millimeters ensures insulation while minimizing interference with the heat dissipation system. However, excessive thickness (such as exceeding 15 millimeters) may affect heat dissipation efficiency and lead to heat accumulation.

Weight and installation: Increasing thickness will increase material weight, which may affect the stability of the gearbox structure. It is necessary to balance insulation requirements and mechanical loads.

2. The influence of material on thermal insulation effect

Fiberglass: Strong high-temperature resistance (up to 300 ℃ or above), low thermal conductivity, suitable for high-temperature environments, but attention should be paid to the harm of fiber dust to health.

Polyurethane foam: good elasticity and sound insulation, but poor high temperature resistance (usually below 100 ℃), easy to aging under long-term high temperature.

Polyester fiber: environmentally friendly and has good sound absorption performance, but has weak insulation ability, suitable for medium and low temperature scenarios.

3. Comprehensive recommendations

High temperature environment: Glass fiber material is preferred, with a thickness controlled at 10-15 millimeters, and ventilation design is ensured to avoid heat dissipation obstruction.

Medium and low temperature environment: polyurethane foam or polyester fiber can be selected, and the thickness can be adjusted according to the actual demand, taking into account lightweight and cost.

Installation process: It is necessary to ensure that the material is tightly adhered to the surface of the reducer to avoid the air layer reducing the insulation efficiency.
