Application Challenges in Compactor Drum

 Compactor drum is the most sensitive part of the machine which comprises of the key elements which plays a major role in compactor performance. The drum is typically designed to withstand the extreme application conditions and to provide longer life and durability to sustain in the extreme conditions and to withstand the dynamic forces in both soil and asphalt compactors.

Drum Bearing Housing -

Drum bearing housing is the most important assembly of a Compactor drum. It consists of the bearing and sealing arrangement which is placed at both the ends of the drum roller. It includes the spindle and the carrier housing along with the bearings. One of the key elements to protect this bearing assembly is the seals. Floating Seals contribute majorly to protect the complete bearing assembly from the external dirt and dust to enter in the drum assembly. It also withstands the extreme operating conditions like high temperature, dynamic loads etc.

Hence bearing housings requires the robust sealing arrangement to provide longer life, lower downtime and strength to the drum assembly. Major challenges in compactor bearing housings are -

·         Seal Failure – Sealing arrangement needs to be very robust in bearing housing as it must withstand the challenging operating conditions like external dirt, dust, asphalt, high temperature etc.

·         Bearing Damage – Failure of the seal arrangement may lead to further failure of bearings.

·         Shaft Damage – Bearing and Seal failure may Seize the shaft and cause down time.
