How Do I Install the Load Shaft on a Hollow Shaft Type Gearhead?

Ms. Ori, you're late! I've been waiting for a long time!
The meeting prolonged. What's wrong with you today?
A customer asked me, "How do you attach a load shaft to a hollow shaft type gearhead?"
Also, I was asked, "Are spacers necessary?" but I couldn't explain it well...
With the hollow shaft type, you can't see what's inside, so no wonder it's difficult to visualize.
I also checked the instructions and illustrations in the catalog, and found that items such as an end plate, a retaining ring for hole, and a spacer are needed for installation.
But I can't quite figure out why it's necessary.
Now I get it! First of all, do you know how to attach the load shaft?
There are 2 ways: using an end plate and using a retaining ring for hole.
That's right. The shape of the load shaft is different, but the actual mounting method is not that different.
Look at the diagrams in the catalog carefully.

◇Using an End Plate

◇Using a Retaining Ring for Hole
You're right! If the load shaft is not a stepped shape, the only difference is that there's a spacer between the load shaft and the retaining ring for hole!
It seems using an end plate is more popular these days.
There's a table that summarizes the role of each component, so take a look.

●Main Role of Each Component

Parts Name	Main Role
Key	Power transmission
Retaining Ring for Hole	Retaining of load shaft
End plate	Bolt receptacle
Spacer 1	Bolt receptacle
Spacer 2	Protection of retaining ring for hole, gap adjustment
Washer	Prevention of loosening of screws
Screw	Fixing of load shaft and gearhead

I see! It certainly had a role.
As for the question "Do I need spacers?", actually, these spacers are very important.
As you can see in the above diagram, the inner diameter of the retaining ring for the hole is large, so without it, the bolt and flat washer that hold the load shaft in place will not catch and fall out.
I also often hear the question, "Where should I place the keys?"
It's difficult to decide whether to place it to the right or to the left...
In the above diagram, the key is located on the left side of the gearhead, but it can be anywhere, as long as the key is attached to the gearhead fits inside the hollow shaft.
That’s right!
I'll go to explain it to the customer right away!
Wait a minute, Vex. Please also introduce the newly released KII Series AC Motor Right-Angle Geared Type.
Of course! There is no reason not to introduce a new product that has all three features: "high torque," "high strength," and "affordable price."
OK, so are you ready to explain it properly to the customer?
Sure!
I got a little carried away...
