STRESS AND STRAIN ANALYZE OF

SMALL ROTATION BODIES OF BEARINGS

 

In the paper is presented the study of tensions and strains ho appears in small radial roller bearings during the compressive strength testing caused by forces acting perpendicular to the roller generator. For modelling a roller bearing Ø 16×24 [mm] we used SolidWorks program, the tests were conducted on two types of rollers with and without defect loaded in five-speeds charging.

STRESS AND STRAIN STUDY OF THE ROLLER BEARINGS USING FEM METHOD

 

This paper aims to study the stresses and strains that occur in small radial bearings with rolls of Æ 7,5×15 mm diameter. We have considered five-speed charging for two distinct cases: without and with defects.

 

Keywords: roller bearing, contact voltage, strain, roll flange

RECONDITIONING MODE OF AGGREGATE WHAT

EQUIPS PUMPING STATIONS

 

There are presenting a new way to increase the pumping efficiency in many pumping station, concerning in pumps working service life optimization. This objective is rational according to the demand to not make inopportune investments (premature or expensive) by replacing or rehabilitating less used pumps. Other reason is to minimize or eliminate, as it possible, to keep on function massive used pumps with low efficiency.

NEW SOLUTIONS FOR HYDRAULIC MACHINES
This is the worlds first time that is possible to simultaneously assure a
two advantage solution by one mathematical & technical elements combination
(provided from hydro-energetic and pumping). There become possible to
manufacture the bigger welded metal sheets viroles on the field better like
before (penstock lower bend, spiral casing and draft tube of the turbine). For
the bigger hydraulic pumps is possible to minimize the manufacturing cost for
draft tube & spiral casing to the double viroles. Finally is obtaining a globally
increase of work efficiency and abrasive & corrosive agents lowest sensitivity
too.
