Abstract

A study has been conducted to investigate unbalance in Valeo hydraulically driven fan systems (HDFS). The principles of balancing have been modeled and applied to HDFS assemblies. The process from the initial build of the part during the molding process to the final completed assembly has been evaluated to determine how to best decrease unbalance in a manufacturing environment. The areas that were deemed to need significant improvement are the couple unbalance specification and the act of inserting balls into the fan groove to correct for unbalance. A new specification of 48 kg-mm2 was recommended and has been introduced to help expedite production cycle times, and a recommendation of a laser system to remove material from the outside of the ring has been made also been made. Preliminary studies have shown that the implementation of a laser balance system could yield very positive results with respect to repeatability and decreased cycle time. Improvement of this process has showed the potential to increase the profitability of Valeo HDFS assemblies in the current automotive market.
