Forms of thrust washers
Thread Content
Help: What standard does the thrust washer in the picture follow?
Is it called a thrust washer? Is its function for thrust application, but it isn’t necessarily called a thrust washer?
Behind the shaft end lock nut, there are 8 equally spaced claws: 7 pointing upward and 1 pointing downward. Who knows what this standard is?
A lock washer is a standard component used in conjunction with round nuts, primarily for fixing purposes; its function is to prevent the round nuts from loosening. JBT 9761-2008 Internal Combustion Engines – Thrust Washers for Crankshafts – Technical Requirements
GB/T 858-1988 – Lock washers for round nuts~~Take a look at this national standard~~
This is not a retaining washer; there is nothing in the middle that fixes it to the shaft
It’s probably some kind of cushion, scientifically known as a relaxation pad
The formats of the standards JBT 9761-2008 and GB/T 858-1988 are different; does anyone know about other standards as well? This gasket is located behind the locking nut on the pump shaft of the FLOWSERVE pump.
