Damping ball bearing | bearing steel truss professional manufacturers | unidirectional sliding ball bearing damping provided by Hao-engineering rubber. Damping ball bearing | bearing steel truss professional manufacturers | unidirectional sliding ball bearing damping is Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) 2014 年 launched a new upgraded steel pendulum column the relative position of the grid bearing the accuracy of the components, the force is uniform. Whether roller bearing steel grid roller allowed crawling, skewed. Whether rocking shaft bearing steel grid tilt. Steel cast concrete pendulum bearing steel grid column note the presence or absence of concrete peeling, cracking, exposed tendons and steel with or without corrosion. In regular testing stage, bearing steel grid defective parts, type, nature, scope, quantity and description of the extent of the external situation carefully and provide typical defects of photographs and pictures. Multi requirements for special bridge inspection report should clearly state the reasons inspection. Special investigation. The so-called special investigation is to always check after regular inspection, bearing steel grid should be based on the status and nature of the damage for dictation specific bridge or steel truss bearing ball bearing damping bidirectional activity, the use of instruments to coordinate awakened Field test activities damping unidirectional ball bearing, load testing machine other ancillary tests, carried out a detailed survey made by check, decided to emergency repair methods goods through special investigations and obtain information on two patches designed to investigate. Furthermore, the survey items bearing steel grid checking operations may include environmental conditions, traffic, bridge bearings MI characteristics and conditions. Steel truss bearing types and causes of deterioration, steel truss bearing deterioration classification, according to railway standards, bearing deterioration abcd class is divided into four railway bridge bearing deterioration rating damping ball branch seat, according to railway standards, steel truss bearing deterioration rating, laminated rubber bearing deterioration rating shows, pot bearing deterioration rating. Evaluation Methods bearing steel grid degradation, according to the provisions of the standard steel truss railway bearing deterioration evaluation method made two provisions, to determine the type of steel truss bearing deterioration and degradation level, should be bright in the optical fiber jumped ah with the naked eye and under appropriate testing equipment checks. How to deterioration of the project, at the time of rating, one of the most serious deterioration should be assessed. Steel truss bearing deterioration and repair of judgment, for the steel truss bearing deterioration or damage to the extent of inspection methods and emergency repair. Countries have different requirements for word, as a reference inferior, judging related bearing steel grid deformation and repair of standard materials, steel truss bridge bearings are interchangeable parts of unidirectional sliding damping Ball bearing, especially steel truss supports, material aging due to its life than concrete, steel side, at the discovery of the fault and the damage be repaired or even worse turn. Establish regular replacement refers again.
