AI Technical Summary
Existing mechanical seals face challenges such as high manufacturing costs due to material removal processes for teeth, mechanical stress on teeth requiring expensive hardening processes, and environmental concerns related to graphite inserts used in sealing.
A mechanical seal design featuring a bayonet coupling for rotational and axial constraint between the annular body and the wave spring, and between the wave spring and the sealing element, eliminating the need for teeth and graphite inserts. The wave spring is constrained to provide uniform force distribution and prevent axial detachment.
The design enhances assembly versatility and safety by preventing axial separation during assembly, reduces manufacturing costs by eliminating material removal processes, and promotes environmental sustainability by avoiding graphite inserts and their associated pollution.
