Gearbox Worm Gear Stripped

The Model: 10TGE 60.1 <<< (10TGE is what we could cypher)

The Model could also be a 10TGF ???

Found these...might check for original patent...

The first two I covered,..

I'll check out the rest, thanks SE

Have you analyzed what caused the gear to strip? It would be a bad thing to wait 11 weeks and then strip another one.

Operator error. This is one critical part of the process where an operator should be there at all times. But plant and upper management (mostly upper management) deems it unnecessary and a waste of man power. (Until it an issue arises)

I could go on, but you get the gist

The product we pump sets up very quickly, we have heat tracers on at all times.

If any down time through out the line occurs, then this area has to monitored closely, if down time exceeds 5 minutes, it has to shut down and flushed out and washed before it sets up.

The heat tracers work against you because the heat tracers are used so it will pump efficiently, but with the pump not running, the temperature window what the product is at is very narrow. If it sits in the pump too long, will cook and set, or if we shut the heat tracers off, it will also set.

I'm no expert, but could something like this save you from having this problem again?

to keep it from stripping yes...

Unfortunately, the other side of the blade......

if the temperature is right at the boundaries where the product will start hardening to a point where the torque couples take effect and slip and not push the slug through, this has happened also, and then we have product hardening in the pump and lines.

Yes, a larger gearbox would help... we're just playing the cards that we were dealt right now.

or a shear pin

or you could put in an electrical overload, to cut below worm strip torque -

or a hydraulic pressure cutout on the pump - once you get it running!

I'd replace the gearbox. Hub City has off the shelf solutions for most applications.

Like to thank everyone for the responses

I called a local machine shop. They do this all the time, I'm bring the box in and they'll measure it up. And machine one.

As far as getting a more available off the shelf item. Not always as easy as that. There are specialty application where it does not allow this. Even though it's a standard box which vendor do have on their line card. It is not a high volume item due to the special process.

We had a screw pump with titanium screws, it took 8 months from the time we put in an order to receive.

in this case, I don't believe this is the case, this case is get what we have, going. But it did shake people up to may be have another on the shelf.
