Wind Turbine Bearing Testing

Friday, October 31st, 2014

Bearings, seals, condition monitoring systems, and lubrication systems are continually made and developed, and they pave the way for more cost-effective wind energy generation.

Equipment manufacturers and wind farm operators continue to come up with solutions that boost the reliability and performance of wind turbine designs, whether they be old or new.

Large wind turbines are humongous machines. That said, the bearings that are used in wind turbines are also enormous, with bore diameters of between 100 mm and 700 mm, and even as much as 2 meters.

Only selected manufacturers across the globe can offer the market a stable supply of such large bearings. It’s a necessity for suppliers to have both production capability and the ability to provide sales and technical service in key areas all over the world, considering the wind-turbine industry is now developing on a global scale.

How to Measure V-Belts

Friday, October 24th, 2014

When measuring V-Belts you need length and width. If you have a belt measuring tool, that would be the best way to go about it. If not, here are ways that you can measure your belt the right way without a special tool.

First, when you measure a belt, you should mark where you start the measurement. This way, you ensure that the measurement is accurate. After having the starting point measured, you can then wrap the cloth tape measure around the belt once. That would give you the outside circumference.

If you don’t have a cloth tape measure, unrolling your belt onto a hard tape measure would be an option. When you use a hard tape measure, though, avoid wrapping the tape around the belt. Doing so will yield an inaccurate measurement.

Here’s how you can measure your belt if the belt is still on the machine and taking it off is not an option for you. Get a piece of string that you’re sure will fit around the belt. Start at one point and wrap around the whole thing coming back to the starting point. After this, remove your piece of string and measure it with a regular tape measure.

In measuring width, just take your tape measure and put it across the top of the belt. That’s it.

Having those two measurements in hand, the outside circumference as well as width, you can then get the proper belt for your application.

This video below will show how to properly measure each of these variables.

SKF Lubrication of Bearings

Friday, October 17th, 2014

With proper lubrication solution, you have a better shot at increasing uptime and productivity. On top of helping keeping premature bearing failures and machine downtime at bay, proper lubrication boosts up energy efficiency.

SKF lubrication solutions range from specialized lubricants to top-of-the-line lubrication systems. Integrated SKF lubrication solutions display their expertise in bearings, seals and condition monitoring. It shows their tribology knowledge – the study of friction, wear and lubrication.

They also take pride in their leading technical support and services, which involves lubrication management programmes to aid in lubricant selection, planning and monitoring.

 

 

How To Replace Skateboard Wheel Bearings

Friday, October 10th, 2014

Having your skateboard bearings replaced, installing new bearings, and putting your cleaned skateboard bearings back can be quite tricky, but once you learn how to go about it, it will become a breeze the next time around.

First off, just set the bearing into the wheel. And then, press the bearing down into the hole, with ample amounts of pressure on the external metal rim of the bearing. Caveat: do not press on the shield or even at the center part of the bearings. Press the bearing on its flat surface with the edge of the wheel.

Do this process with all the other bearings, putting one on each side of every wheel. It would be best to have the shielded side of the bearing facing out on each.

With the use of your skate tool or a socket wrench, slowly tighten every nut down. Doing so will push the bearings down into the wheels. See to it that you do it carefully to avoid cranking too hard or fast on the nuts. Otherwise, you may damage the bearings. Tighten them all up until they feel snug, and then stop. Don’t overdo it. Aim for the nuts to fit on snuggly, as well as to be done turning.

Proper Engine Oil For Different Car Brands

Friday, October 3rd, 2014

As opposed to what a considerable number of car technicians presume, they’re able to pick the lube brand they make use of in their automobile repair shop.

It has been established that car mechanics are not required to conform to lubricant brand suggestions from car makers. However, despite the fact that you’re free to decide on the brand of lubricants, guidelines with regard to type of oil are to be adhered to.

There are companies out there that have a wide array of engine oils, and they correspond with the oil type specifically required by a given car brand, and accredited by the car manufacturer.

That being said, how would you know which oil to use for which car brand?

First off, make use of the suggestion tool on certain websites. You can even fill forms like ‘Find the right lubricant for your vehicle’ in some sites. You can straight away get professional recommendation for the best motor oil for your vehicle.

So as to help car mechanics in doing their meticulous work, you can do your research and look up some poster that gives a straightforward and clear view on the right engine oil for prominent car brands like Volkswagen, Renault and Citroen.

A little bit of research can pay off.
