The preferred choice for small and medium-sized granulators! Detailed explanation of K87 gearbox adaptation conditions and usage advantages

1、 Core usage advantages

1. Hard tooth surface design, strong durability under heavy loads

The granulator generates a significant impact load when extruding materials. The internal gears of K87 reducer are made of high-quality alloy steel and undergo carburizing quenching and precision gear grinding processing. The tooth surface hardness can be stably controlled within the range of 58-62HRC. This hard tooth surface design significantly enhances the contact fatigue strength of the gear, effectively resisting early wear and pitting under heavy load conditions, ensuring long-term stable operation of the equipment.

2. Compact layout of right angle axis, saving installation space

The K87 reducer adopts a straight axis (right angle axis) layout, with the input shaft and output shaft forming a 90 ° angle. This compact structure effectively shortens the axial length and is very suitable for heavy-duty equipment such as granulators that require installation space and vertical or side installation, reducing the complexity of the overall mechanism design.

3. Smooth and low-noise transmission, high operating efficiency

Thanks to the combination transmission of helical gears and spiral bevel gears, as well as the application of computer shaping technology, the K87 reducer has minimal dynamic load and speed fluctuations during meshing. This not only ensures a smooth transmission process and high load-bearing capacity, but also effectively reduces operating noise and vibration. Its average transmission efficiency can usually reach over 94% -95%, significantly reducing energy consumption.

4. Modular and diversified configuration, flexible adaptation

The K87 reducer adopts a modular design with a unit structure, supporting various methods such as foot installation, flange installation, and hollow shaft installation. At the same time, it can flexibly match motors of different powers (such as variable frequency motors, brake motors, explosion-proof motors, etc.) to meet the speed regulation and start stop requirements of the granulator at different process stages.

2、 Adapt to working conditions and environmental requirements

To ensure optimal performance of the K87 reducer in pelletizer applications, it is recommended to meet the following operating and environmental conditions:

Temperature and heat dissipation: The optimal working environment temperature should be maintained between -10 ℃ and 40 ℃. If the ambient temperature in the granulation locomotive room is too high, it is necessary to ensure good ventilation conditions around the reducer to assist in heat dissipation, and cooling devices can be added if necessary.

Load control: K87 reducer is suitable for medium and heavy load conditions. During continuous operation, it is recommended to control the load rate within 85%, and the instantaneous peak torque should not exceed 200% of the rated value to avoid overloading affecting the service life of the equipment.

Environmental requirements: The humidity should be kept moderate (50%~80%), avoiding use in environments containing strong corrosive substances or severe vibrations to prevent internal component corrosion or seal failure.

Installation accuracy: The installation base should be flat and sturdy, and the longitudinal and transverse horizontal deviations should be controlled within ≤ 0.1mm/m; If a coupling is used to connect the motor, precise coaxiality calibration is required to eliminate additional stress and ensure smooth transmission.

In summary, the K87 reducer, with its high torque, impact resistance, compact structure, and high transmission efficiency, perfectly meets the strict requirements of power transmission for small and medium-sized granulators, and is an ideal choice for improving the stability and production efficiency of granulation production lines.
