Mar. 8, 2017 Metal belt life and S-N curve

Now let us continue to talk about belt life.
Our belts and sleeves are made from metal. 
Metal experiences 'metal fatigue.' This fatigue strength is described by 'S-N curve = stress-number of bendings' as below.

Fatigue strength is determined by bending stress, tensile stress and crown radius of pulleys.
And in case of a welded belt, toughness around the welded area determines belt life.
Dymco strictly control this welding process to keep high belt quality.

Furthermore we have developed combination of heat treatment and rolling technology in ring-rolled belts and thin-wall sleeves.  The original welded line in these products show almost same level of hardness and tensile strength as the parent material.

Metal lives long when stress becomes less.
What about humans?  We have to stand work as well as mental stress.
Have you ever seen S-N curve of a human body?

2017. Mar. 1st- Life test of metal belts

I want to be strong and tough.  How about you?

When it comes to steel belt, there is a life factor in belt properties.
Japan industrial standards stipulates hardness and tensile strength of each steel grade, but we do not know how long one belt continues to rotate in small pulleys or large pulleys.
So Dymco examines it  in our lab to know for sure how long one belt works.  It takes dyas, so everyday some belt is under life test day and night in our lab.

One stainless steel belt is expected to go beyond bendings of 10 million times.  Belts in a picture below are after 10 million bendings.  We do not find cracks or damages at all.

We continue this life test to get to know for sure life of belts.

2017.2.15 Oil skimmer belt

Do you know this simple phenominon?
Oil easily stays on metal.
Oil skimmer belt makes use of this.
Cloth and plastics are made oil skimmer belts.
But metal oil skimmer belt is very good at catching oil, life, anti-wear, anti-heat, and anti-corrosion.    
Please let us know your pulley diameter.  We recommend adequate belt size.

2017.02.01 Power Transmission Metal Belt @ DYMCO, ATX WEST HALL B #4381

We display power transmission belt, too, at ATX WEST next week.
There is increasing deman for it especially in vacuume environment.
We select the best steel grade and belt process for each application.

We wish we could meet as many sales representatives, metal belt users, and visitors as possible there.

2017.01.25 Stainless Steel Belt Conveyor at ATX WEST Feb. 7-9

We will show our standard stainless steel belt conveyor, too.

You will watch what metal belts is set, how smooth or flat it is.
It will be understood quite easily that this conveyor can work inspection by laser or camera, for this provides flat stage all the time, continuously.

We wish we could meet as many sales representatives, metal belt users, and visitors as possible there.

See you then!
