QZ spherical bearings are made of a support plate including stainless steel plate, lower bearing plate, ball cap liner, Teflon slide (i.e. flat PTFE plate, spherical PTFE plate) and dust-proof structure and other components. Compared with the ordinary rubber bearings, its corner, rotating more flexible, larger capacity, allowable displacement volume and other characteristics, and able to adapt to needs of large rotation bearing totally,which are widely used in curved bridge, straight bridge, skew bridge and city overpass bridge projects.
Function and Usage:
1>QZ ball bearing by the attendance board, the male intermediate plate and Teflon board consisting of two different shapes. Road intermediate plate is a concave spherical surface, corresponding with the male intermediate plate, with a curved PTFE sheet lining between the two, through a spherical slide to meet with the beam end rotation; stainless steel plate and the intermediate plate Theravada another PTFE sheet on the composition of the second slide surface complete telescopic beam displacement generated due to temperature factors.
2>Ball bearing force transmission reliable, consistent performance each rotated, not only with pot rubber bearing load capacity, the horizontal displacement of large features, also meeting the needs of a large corner for wide bridge, curved bridge. Because of no use rubber parts to pressure parts, rubber low temperature brittleness and other effects of aging doesn't exist, which particularly suitable for low-temperature places.
QZ ball bearing main technical performance
| The support reaction force (vertical bearing capacity) is divided into 16: 1000KN, 1500KN, 2000KN, 2500KN, 3000KN, 4000KN, 5000KN, 6000KN, 7000KN, 8000KN, 9000KN, 10000KN, 12500KN, 1500KN, 17500KN and 20000KN. |
| The bearing angle into 0.02,0.04,0.06rad. (Can be increased if necessary) |
| Bearing friction coefficient of PTFE plate design has under grease lubrication conditions, stress is about 30MPa, values are as follows: Normal temperature (-25 ºC ~ + 60 ºC) 0.03 Low temperature (-40 ºC ~ + 60 ºC) 0.05 |
| The carrier can withstand the horizontal force; Unidirectional movable bearing (DX) transverse to the horizontal force of support reaction force of 10% Fixed bearing (GD) to withstand the horizontal force of support reaction force of 10% |
