Table of Standards and Measures: Flanges and Industrial Connections

During the development of projects related to industrial pipelines, various standards queries are required., measures and products. We present below an interesting dimensional and theoretical table, which facilitates consultation within various standards and pressure classes of industrial flanges and connections. You can also consult the equivalence between materials, dimensions of the holes of the […]

Bearings

Bearing is a part that guarantees the mobile connection between two elements of a mechanism., allowing between them to rotate. It is intended to allow rotation under load, accurately and with minimal friction. The Foundation The concept behind a bearing is quite simple: things run better than they slide. the wheels […]

roller chains

Roller chains are a transmission option when the torque involved in the design is not supported by a belt transmission, when the system does not allow transmission slippage or when there is a special request, such as transporting materials with the use of additions to chains. There are currently several types on the market, […]

A well-studied Transmission equipped with belts of suitable types and sizes offers an economical and safe system for power transmission., além disso, There are several benefits to using straps.. In power transmission through belts, a wide variety of multiplications or reductions and, when necessary, these multiplications […]

Coil Springs - Calculation Workbook

The Spring It is a single element or an association of elements (system) capable of assuming remarkable elastic deformations under the action of forces or moments, e, therefore, able to store a large amount of elastic potential energy. The characteristic elements of springs are the arrow, rigidity and flexibility. arrow is the […]
