1、概述
1, overview
QZ系列球型支座是由上支座板、下支座板、球形板、聚四氟乙烯滑板（F4、球面四氟板）及橡膠擋圈組成的一種特殊盆式橡膠支座產(chǎn)品。
QZ series ball bearing is a kind of special basin type rubber bearing product composed of upper support plate, lower support plate, spherical plate, polytetrafluoroethylene slide plate (F4, spherical Teflon plate) and rubber ring.
它將盆式支座中的橡膠板改為球面四氟板因而得名,由于QZ球型支座中間鋼板及底盆亦相應地改成球面，減小了摩擦系數(shù)。其位移由上支座板與平面四氟板之間的滑動來實現(xiàn)。
It changed the rubber plate in the basin support to the spherical Teflon plate, hence its name, because the QZ ball bearing, the middle steel plate and the bottom basin were correspondingly changed into spherical surfaces, and the friction coefficient was reduced. The displacement is realized by sliding between the upper support plate and the plane Teflon plate.
在上支座板上設置導向槽或?qū)颦h(huán)來約束支座的單向或多向位移，可以制成球形單向活動支座和固定支座。通過球形板和球面四氟板之間的滑動來滿足支座轉(zhuǎn)角的需要、
A guiding groove or a guiding ring is arranged on the upper support plate to restrict the unidirectional or multidirectional displacement of the support, and can be made into a spherical one-way movable support and a fixed support. The sliding angle between the spherical plate and the spherical plate can meet the requirement of the bearing rotation,
2、優(yōu)點
2, advantages
QZ球型支座以傳力可靠，轉(zhuǎn)動靈活的特點，不但具有GPZ盆式橡膠支座承載能力大的特點，座位移大等特點，而且能更好地適應大轉(zhuǎn)角的需要，與普通盆式支座相比具有下列優(yōu)點：
QZ ball bearing with reliable power transmission, flexible rotation characteristics, not only has the GPZ basin type rubber bearing large carrying capacity, seat shift and other characteristics, and can better meet the needs of a large angle, compared with the ordinary pot bearing has the following advantages:
1、球形橡膠支座通過球面?zhèn)髁Γ粫霈F(xiàn)力的縮頸現(xiàn)象，作用在混凝土上的反力比較均勻；
1, the spherical rubber bearing through the spherical transmission force, no force necking phenomenon, the role of the reaction force on the concrete more evenly;
2、球形支座通過球面聚四氟乙烯板的滑動來實現(xiàn)支座的轉(zhuǎn)動過程，轉(zhuǎn)動力矩小，而且轉(zhuǎn)動力矩只與支座球面半徑及聚四氟乙烯板的摩擦系數(shù)有關(guān)，與支座轉(zhuǎn)角大小無關(guān)，特別適用于大轉(zhuǎn)角的要求，設計轉(zhuǎn)角可達0.05rad.
The rotation process 2, spherical bearing by sliding spherical Teflon plate to realize bearings, small rotating torque, and rotational torque on the friction coefficient and radius of the spherical bearing and Teflon plates, has nothing to do with the bearing angle, and is especially suitable for large angle, the design angle can reach 0.05rad.
3、QZ球型支座各向轉(zhuǎn)動性能一致，適用于寬橋、曲線橋；
The 3 and QZ ball bearings have the same isotropic rotation performance, and they are suitable for wide bridges and curved bridges;
4、這種支座產(chǎn)品不用橡膠承壓，不存在橡膠老化對支座轉(zhuǎn)動性能的影響，特別適用于低溫地區(qū)。
4, this kind of bearing products do not use rubber pressure, there is no rubber aging on the bearing rotation performance, especially for low temperature areas.
3、球型支座的分類
3. Classification of spherical bearings
球形支座通過球面?zhèn)髁?、不出現(xiàn)力的縮頸現(xiàn)象，作用在混凝土上的反力比較均勻； 球形支座通過球面聚四氟乙烯板的滑動來實現(xiàn)支座的轉(zhuǎn)動過程，轉(zhuǎn)動力矩小，而且轉(zhuǎn)動力矩只與支座球面半徑及聚四氟乙烯板的摩擦系數(shù)有關(guān)，與支座轉(zhuǎn)角大小無關(guān)。
Necking spherical bearing by force, not spherical force, reacting force in the concrete is uniform; rotation of the spherical bearing by sliding spherical Teflon plate to realize bearings, small rotating torque, and rotational torque on the friction coefficient and radius of the spherical bearing and Teflon plates, has nothing to do with bearing angle.
因此特別適用于大轉(zhuǎn)角的要求，設計轉(zhuǎn)角可達0.05rad以上。支座各向轉(zhuǎn)動性能一致，適用于寬橋、曲線橋等； 支座不用橡膠承壓、不存在橡膠老化對支座轉(zhuǎn)動性能的影響，特別適用于低溫地
Therefore, the utility model is especially suitable for the requirements of large rotation angles, and the design angle can reach more than 0.05rad. The supporting bearing has the same properties of rotation, which is suitable for wide bridges, curved bridges, etc. the bearings do not need rubber pressure and there is no effect of rubber aging on the rotation performance of the bearings, especially for low temperature
