Hengshui Haotong Engineering Rubber Co., Ltd. The original Hengshui Haokun Engineering Rubber Factory was founded in 2001, covering an area of 8,000 It covers an area of 500 square meters and currently has 156 employees, including 38 professional and technical personnel. Our company is a key manufacturer specializing in the production of rubber products and supporting products for transportation facilities.

, The spherical rubber bearing transmits force through the spherical surface, and there will be no force necking phenomenon. The reaction force acting on the concrete is relatively uniform
. The spherical rubber bearing transmits force through the spherical polytetrafluoroethylene surface. The rotation process of the support is realized by the sliding of the plate. The rotation torque is small, and the rotation torque is only related to the spherical radius of the support and the friction coefficient of the PTFE plate, and has nothing to do with the size of the support angle. It is especially suitable for large rotation angle requirements. The design angle can reach up to br/>, and the spherical bearing has consistent rotation performance in all directions. It is suitable for wide bridges and curved bridges. This bearing product does not use rubber to bear pressure, and there is no impact of rubber aging on the rotation performance of the bearing. It is especially suitable for in low temperature areas.
Characteristics of spherical steel rubber bearings
The spherical rubber bearing has reliable force transmission and consistent rotation performance in all directions. It not only has the characteristics of large load-bearing capacity and large horizontal displacement of basin-type rubber bearings, but also can adapt to The need for large turning angles is suitable for wide bridges and curved bridges. Since the pressure-bearing parts do not use rubber parts, there is no impact of low-temperature brittleness of rubber, so it is especially suitable for low-temperature areas. The implementation standard of this series of rubber bearings is/"Technical Conditions for Ball Bearings".
Installation methods and precautions for spherical rubber bearings
When the spherical rubber bearings produced by our company leave the factory, the bearings have been leveled and the connecting bolts have been tightened to prevent the spherical rubber bearings from Turning and overturning occurred during installation. We can preset the rotation angle and displacement according to the user's design needs, but the construction unit should put forward the requirements for the preset rotation angle and displacement before ordering, and the manufacturer will pre-adjust it during assembly.
Before installation, the bridge construction unit can unpack and check the packing list, including the accessories list, a copy of the inspection report, the rubber bearing product certificate and the bearing installation and maintenance details. After the construction unit unpacks, the connecting bolts are not allowed to be rotated arbitrarily, and the supports are not allowed to be arbitrarily disassembled.
, When installing the spherical bearing, the installation height should meet the design requirements, and the plane of the rubber bearing should be ensured to be level and flat. The height difference between the four corners of the supporting surface of the spherical bearing shall not be greater than.
The bridge maintenance unit must conduct regular and strict inspections of the bridge bearings every year, remove debris and dust near the spherical rubber bearings, and carefully wipe away the dust on the stainless steel surface with cotton to ensure that it can be used.
Main technical properties of spherical steel bearings
Spherical steel bearings can be divided into grades according to the reaction force bearing capacity,,,,,,,,,,,,,,,,, when the bearing capacity is greater than Design and processing.
, The design rotation angle of the spherical bearing is divided into, the displacement amount of the spherical bearing is along the bridge direction ~, ~ and. The transverse bridge uses multi-directional movable supports. The design displacement can be changed according to project needs.
, The design friction coefficient of the spherical steel bearing is as follows when the polytetrafluoroethylene plate is lubricated with silicone grease and the stress is about The horizontal force borne by the longitudinal movable bearing and the transverse horizontal force of the bridge is the reaction force of the bearing. The horizontal force borne by the fixed bearing is the reaction force of the bearing.
