Warmly celebrate ningbo corebone elevator accessories co., LTD. Official website opened!
Advantages of CoreBone rolling guide shoes: all roller parts are produced and imported by Korean factories. Special rubber formula, high resilience, low permanent deformation, low noise, excellent dynamic fatigue performance. Adopt international leading viscose material and advanced viscose technology. Scientific and rigorous professional vulcanization production line to ensure stable product quality. The imported NSK bearing, KBC bearing and "Humanistic C & U" customized bearing with stable performance are adopted. Reasonable support structure design, inheriting the classic, fully showing the combination of strength and beauty. Large scale use of casting technology, more stable and safer. Precision professional testing equipment ensures 100% qualified rate of products.
CoreBone roller guide shoe, the structural components include: ① casting base, ② roller assembly, ③ connecting rod adjusting device, ④ dust cover assembly. It is characterized in that: three groups of roller components are installed on the casting frame base through adjustable connecting rod positioning device, reasonable and classic design, compact structure, wear-resistant, noise-free and long service life of synthetic rubber material on roller surface, and quick adjustment of roller group and connecting rod device.
① Casting base: the whole casting of the base frame is selected for the base of the corebone roller guide shoe instead of the plate welding. The whole casting of the base can ensure the dimensional machining accuracy requirements and the base deformation after machining. No matter how old the welding plate is, how stress relief, machining precision and deformation after machining are, the stability of the long-term use is not as good as the whole casting Good manufacturing, such as precision equipment frame, machine base, engine shell, etc. all choose casting instead of welding plate, so the base of corebone roller guide shoes series products basically choose frame casting.
② Roller assembly: the roller assembly is composed of two sides pressing respectively on the wall surface of both sides of the elevator guide rail and one group of roller assembly pressing on the end face of the elevator guide rail. Three groups of roller assembly tightly clamp the hoistway guide rail in three directions, playing a good positioning role, so as to ensure the smooth operation of the elevator. The three groups of roller components are composed of aluminum die-casting hub and special synthetic rubber wear-resistant layer wrapped on the outer circle by vulcanization process. The wear-resistant layer is made of special synthetic rubber material, which can greatly improve the wear resistance, no noise and prolong the service life of the roller on the elevator. Greatly reduce the cost of replacement and maintenance times in the later stage.
③ Connecting rod adjusting device: one end of the connecting rod device is fixed on the base by bolts, and the middle part of the other end is equipped with a compression spring, which is on the screw between the positioning nut and the connecting rod, and the middle screw is equipped with a rubber stopper. The front end is connected with the roller assembly by bolts, and the connecting rod adjusting device can adjust the size between the roller and the guide rail and the relative position between the rollers through the compression spring, so as to tighten the guide rail, reduce the shaking and vibration feeling of the elevator during operation, and greatly improve the comfort of the passengers. The connecting rod adjusting device adjusts the tension size of the compression spring by adjusting the roller position, which is simple, convenient and fast Save time, adjust the relative position of the roller according to the different model of the guide rail, which is suitable for the use of various specifications of the guide rail, thus greatly reducing the production cost.
④ Dust cover plate: the dust cover plate is installed on the upper end of the base through bolts, which can cover the roller assembly and prevent dust falling Function on the roller.
