How is this hub installed on the shaft?
Thread Content
I don’t see any keys; it probably isn’t the red version. Is there any brother who knows about this? It’s on the motor shaft
It’s true, it’s hard to understand; let’s have a full photo so we can all analyze it together
Is it a cone sleeve? The rear wheel of a compressor is pushed forward by an oil pressure actuator
Is that a thread on the shaft? If so, it should be a cap, right?
The half coupling of the cone sleeve is secured against loosening by a lock nut with four holes. Use the high and low hydraulic pumps to position the half coupling in the desired location. A set of specialized hydraulic tools is required.
What is this device? Why does it look like a press?
The information regarding the foam boards, as well as those on floors 3 and 6, has already been explained clearly~~~~ If you still don’t understand, just ask Xiao Du: “Keyless transmission””~~~~
