Installation and Operating Environment of Butt Couplers
Butt couplers shall be installed in a dust-free and clean room. They must be carefully selected and matched; the spacers used for butt couplers shall be ground. On the premise that the inner and outer ring spacers are kept at the same height, the parallelism of the spacers shall be controlled within 1μm.
Butt couplers shall be thoroughly cleaned before installation. During cleaning, the slope of the inner ring shall face upward, and the coupler shall feel flexible without stagnation. After air-drying, a specified amount of grease shall be applied; if oil mist lubrication is used, a small amount of oil mist oil shall be added.
Butt couplers shall be stored in a clean, ventilated environment free of corrosive gases, with a relative humidity not exceeding 65%. For long-term storage, regular rust prevention measures shall be taken. Special tools must be used for installing butt couplers to ensure uniform force application; knocking is strictly prohibited.
If foreign matters such as iron filings, burrs, or dust enter the butt couplers, they will cause noise and vibration during operation, and may even damage the raceways and rolling elements. Therefore, before installing butt couplers, it is essential to ensure that the installation surfaces and environment are clean.
After installation, if the butt couplers are not carefully aligned and straightened, the rotating couplers may be subjected to additional loads, friction, and vibration. These factors can accelerate fatigue, reduce the service life of butt couplers, and may also shorten the service life of other machine parts. In addition, increased vibration and friction may significantly increase energy consumption and the risk of premature failure.
