Стопорное кольцо расширителя ролика Caterpillar 4C6738

The Roller Expander Retaining Ring maintains the expander in a specified state, allowing rollers to remain engaged at the intended expansion level while motion or load transfer occurs. Limiting unintended axial or radial movement, the ring supports uniform roller contact behavior throughout the operating cycle. This control allows predictable interaction between the roller expander and adjacent working elements during rotation or movement. The retaining ring also supports service procedures by allowing removal and reinstallation of the expander without disturbing surrounding functional relationships.Attributes:• Controls retention of the expander in an expanded state.• Limits the unintended radial and axial movement of the expander.• Manages interaction between rollers and mating surfaces.Applications: The Roller Expander Retaining Ring is used with the sleeve replacement tool group to secure injector sleeves in the injector bore, maintaining a positive seal and proper alignment during removal and installation operations.
