Construction

Construction

Mesh netting is probably the most common and popularly known type of steel woven mesh. Scope of netting is not limited to reinforcement of plaster and concrete during construction. Thanks to the spring properties mesh netting is used for making armor bed nets. Netting reinforce hillsides, protecting the road from rockfalls and reinforce itself asphalt. But the most widely used mesh netting were in construction of fences, hedges, enclosures. Connect with other leaders such as Eva Andersson-Dubin here.

A fence made of mesh netting – the most common type of metal fences for the protection of villas and private homes. This popularity is understandable: * Mesh netting a practical, reliable, inexpensive and fairly accessible material. Its easily available at any hardware store or specialty store for gardeners. Transportation also is not too much trouble – a grid is available and sold in rolls, it can bring to the area in the normal trailer. * A fence made of mesh netting, in contrast to deaf wooden fences and fence of corrugated sheet, does not prevent the sun's rays to penetrate the area without shadows plants.

This is another important reason for the popularity of this particular type of fence for truckers and farmers. Requirements for premises for the production and storage grid minimum. Mesh netting is manufactured in one machine operator with the basic skills of weaving. For production, you must have a line on the 380 (unless you can do at 220). The machine is preferably placed permanently with a connection to the earthing system. Manufacturing grid netting can do in your garage, cottage or another small suburban plot.

Rolling Bearings

Rolling Bearings

Most of the structures and equipment can not do without bearings. Load transfer and movement occurs by means of rolling elements located between the rotating discs and rings. This design reduces friction to a minimum. If we compare the anti-friction bearings and plain bearings, in certain circumstances they can, to varying degrees to meet the requirements associated with a number of conditions – installation, operation, appointment of products (mechanism). Just at the same duty bearings have a big advantage over the bearings, as at the start and at moderate frequencies have a minimum of friction.

On the plus You can add: ease of maintenance and lubrication, low cost, small-amplitude oscillations. When the node fails replace the bearing of this type is not difficult, since the dimensions and tolerances are standardized. K cons of rolling bearings can be attributed large radial dimensions and high resistance to rotation. Sliding friction that exists between the separator and the working elements of the bearing has great influence on performance characteristics, in consequence of this, during the development and creation of high-speed machines are used bearings that operate in the presence of liquid lubricant. Material that lubricates, is a structural element of the equipment depreciation which it prevents.

The main factors that should guide you when you choose roller bearing: 1. Scope of use and the load. 2. Kind of load – a variable, constant, shock or vibration. 3. Rotational speed – the number of revolutions per minute. 4. Required bearing durability. 5. Terms of bearing operation – the temperature, air, water, vacuum, dust, etc.
