First, the product introduction
GCQZ series ball bearing consists of upper seat plate, lower seat plate, spherical wear plate, flat wear plate, ball plate, rubber seal ring and anchor components. Bearing capacity is divided into vertical bearing capacity of 1000KN ~ 60000KN a total of 35 specifications, its structure on the basis of ordinary spherical bearings, wear-resistant plate material modified ultra-high molecular weight PTFE, a good wear resistance and Self-lubricating, improve the bearing life, reducing maintenance, maintenance costs.
GCQZ (I): fixed bearing, one-way movable bearing in the direction of the horizontal bearing capacity of the vertical bearing capacity of 10%, generally applicable to peak ground acceleration acceleration Ag ≤ 0.05g bridge region;
GCQZ (Ⅱ): fixed bearing, one-way movable bearing in the direction of the horizontal bearing capacity of the vertical bearing capacity of 15%, generally applicable to the peak ground acceleration acceleration Ag ≤ 0.1g bridge region;
GCQZ (Ⅲ): fixed bearing, one-way movable bearing in the direction of the horizontal bearing capacity of vertical bearing capacity of 22.5%, generally applicable to the peak ground acceleration acceleration Ag ≤ 0.15g bridge region;
Two-way moving type support, the direction of the one-way movable bearing horizontal movement of the shear check the vertical bearing capacity of 5% of the design.
Second, product characteristics
1) The ball crown liner with hard chrome plating process, it has a high wear resistance and low coefficient of friction to improve the use of bearing performance;
2) bearing vertical curve angle 0.02rad, at the same time to adapt to any angle within the flat curve, flexible rotation;
3) wear-resistant plate with modified ultra-high molecular weight polyethylene, to meet the needs of a large bearing capacity also has good wear resistance and self-lubricating to improve the bearing life, reducing maintenance, maintenance costs;
4) Ambient temperature range (-40 ℃ ~ +60 ℃), can be used widely;
5) Under the seat plate anchor plate welded ear plate structure, to meet the requirements of the level of stiffness, reducing the amount of steel, a significant economic benefits;
6) bearing friction coefficient of less than 0.03, with the use of lubricating grease, which greatly improves the bearing life.
Third, product applications
GCQZ series of ball bearings strict implementation of the People's Republic of China traffic industry standards JT / T 17955-2009 "bridge ball bearing", the European standard EN1337.7-2005 requirements and related industry specifications developed bridge standard components product requirements.
My company has technology conversion GCQZ (I, Ⅱ, Ⅲ) (1000 ~ 60000) KN series of ball bearings. Applicable to all types of highways, roads and rail transit bridges.
