Tianjin elastic ball bearing hinge ball joints _ seismic bearing brand factory outlets _ Limit elastic ball hinge support provided by Hao-engineering rubber. Tianjin elastic ball bearing hinge ball joints _ seismic bearing brand factory outlets _ Limit elastic ball bearing hinge is Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) 2014 年 new upgrade introduced in the role (or load) The maximum angle under the most unfavorable combination 0.02rad, this value should comply with the relevant provisions of the standard or given by the designer. Under the proper use of state poor corner, this value should comply with to have any standards, the general should meet the design requirements. Ball bearing hinge flip when changing variable rotation under load occurs, the variable rotation will cause the rotation of wear, ball bearing hinge will affect the seal durability. Turn the trajectory design range, according to the following formula should be determined according to the design requirements. The actual change in the scope of gray machine design vehicle load caused the number of bearing service life of the vehicle under the design angle difference between the amount of the correction factor bearing bottom basin diameter, test and track the actual rotation range, usually 5, Fan rotation trajectory, ball bearing hinge foreign test data shown below. Pot bearing rotation constraints, and constraints caused by the rubber sheet caused by seals Huan moving, rubber sheet maximum restraint in accordance with the following provisions. Ball bearing hinge maximum restraint moment generated by elastic rubber plate diameter ball joint bearing, permanent total use, variable-angle effect caused by the restoring moment coefficient at zero rotation; under constant load eccentricity, rubber sheet no run case moment, pilot testing devices coefficient, using two pot bearing with a sliding surface of the test device, using a ball bearing hinge pot bearings with a spherical bearing static testing device. Rubber sheet average pressure, have restored the next moment coefficient rotation Run circumstances. Eccentricity, ball bearing hinge case the lower limit has run elasticity ball bearing hinges, moment no run case, when the rotation under no circumstances run recovery from the coefficients. Ball bearing hinge on the roof at the bottom of the basin with a surface due to the friction generated additional moment should be considered, in order to determine the value of this moment, the bottom and the top surface of the ring basin largest coefficient of friction on ball joints should go 0.2 bearing in pots developed on the basis initiated on the basis of style on a ball bearing hinge bracket, back in the 1970s, it developed into a spherical foreign holder, China has also started to develop in 1988 and began a spherical bearing used in engineering practice , completed in 2000 national standard setting work, the spherical bearing not only involve the corner and all aspects of carrying capacity to adapt to the range of large bearings than ball joints, so enter the 1990s, the spherical bearing in our long-span bridge engineering on has been more widely used, and completed the revision of the national standard in 2008, while the completion of the core standard package involves the design drawings. General construction spherical bearing, ball bearing hinge support by the board, spherical steel liner plate, the ball bearing slide hinge flat PTFE skateboards, skateboard fixed elastic spherical ball joints PTFE bearings, seals rings and dust cover and other components to make the composition, role and structure of spherical bearings require its major components. Ball bearing hinge plate can also be called the end of the basin, usually made of steel castings, bearings also useful for small tonnage processed thick steel case, the next major act bearing plate fixed spherical PTFE sheet, and will stand reaction force is transmitted to disperse or bridge piers supporting the platform. Sliding ball joint rotation by sliding spherical bearing steel liner plate and spherical PTFE sheet between to achieve, but usually spherical steel liner plate steel castings finishing, ball joints and spherical bearings for processing completed Flexible ball joint bearing, now there are situations using coated stainless steel surfaces. If after using steel processing, machining precision spherical rotation function will refer directly affect the bearing, which points to attract attention.
