Our roads and bridges using a ball bearing hinge experienced during the execution of the standard, in 2007 began to standard technical specifications were revised again, the ball bearing hinge series of specifications have to do some changes, from our roads and bridges pot bearings The development, its adaptability corner from the maximum angle position 0.001rad GPZ development GPZ (II) the maximum angle position 0.02rad, ball bearing hinge maximum carrying capacity also increased from 50000KN to 60000KN, the situation is also true of China's railway . Here is the client in order to understand the use of the GPZ and GPZ (II) Basic Specifications Series listed for reference purposes only. Ball bearing hinge according to current standards, according to the bearing type to adapt to room temperature, and the temperature range is divided into two kinds of cold steel ball bearing hinge free installation guide, by the use of performance is divided into two-way bearing activities, southeast to support activities Three types of seat and the fixed bearing. Ball bearing hinge series of specifications, technical performance GPZ, the ball bearing hinge vertical angle of not less than 0.001rad, vertical bearing capacity of 1000 ~ 50000KN divided into 28 horizontal bearing capacity of the non-slip surface is vertical 10% of the friction coefficient in the desired pattern classification. In addition to stainless steel sliding surface grid professional manufacturer of ball bearing hinges, should be regularly carried out bearing steel paint anti-rust treatment. When the bridge connecting bridge bearings, it is important twisting point substructure, fine structure. Some call back spine of the bridge, due to ball joint mount itself quality problems, as well as the design, installation, improper use of the process in the various hinge bearings, plus many years in the field of environment bearing the image atmosphere, ball Hinge Supports most prone to the disease, resulting in premature bearing damage, it will seriously affect the normal use and life of the bridge. Especially in the early construction of the bridge some food, the widespread loss of oxygen in a long time problem. Ball bearing hinge aging, rusting steel hinge bearing failure bidirectional ring design finished processing, there are some small scissors supported girder span bridge originally not set formal bearing. Making these bridges in the large tonnage, high traffic loads, there has been a series of problems, the ball bearing hinge bearing an urgent need to carry out the replacement and maintenance.
