JQZ ball bearing
First, the product introduction
JQZ series ball bearing consists of upper seat plate, lower seat plate, spherical wear plate, flat wear plate, ball plate, rubber seal ring, guideway assembly and anchor assembly. Bearing vertical bearing capacity is divided into 1.0MN ~ 70MN a total of 33 specifications, its structure on the basis of ordinary spherical bearings, wear-resistant plate material using modified ultra-high molecular weight polytetrafluoroethylene, a good wear resistance And self-lubricating, to improve the bearing life, reducing maintenance, maintenance costs.
JQZ (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 the peak ground acceleration acceleration Ag ≤ 0.10g bridge region;
JQZ (Ⅱ): fixed bearing, unidirectional movable bearing The horizontal bearing capacity is 15% of the vertical bearing capacity, which is generally applicable to the bridge with the peak acceleration of ground motion 0.10g≤Ag≤0.15g.
JQZ (Ⅲ): fixed bearing, one-way movable bearing in the direction of the horizontal bearing capacity of the vertical carrying capacity of 22.5%, generally applicable to the peak ground acceleration 0.15g ≤ Ag ≤ 0.20g 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) the use of anchor bearings with higher anti-corrosion performance Dacromet surface treatment process to improve the anti-corrosion performance of the anchor;
6) bearing friction coefficient of less than 0.03, with the use of lubricating grease, which greatly improves the bearing life.
Third, product applications
JQZ series of ball bearings strict implementation of the People's Republic of China traffic industry standard JT / T 17955-2009 "bridge ball bearing", the European standard EN1337.7-2005 requirements and related industry specifications developed bridge standard components product requirements.
I have technology companies have JQZ (I, Ⅱ, Ⅲ) (1000 ~ 70000) KN series of spherical bearings. Applicable to all types of highways, roads and rail transit bridges.
