Pressed bearing seat
- Our company produces various specifications and models of special stamping bearing seats for rollers, which have the advantages of light weight, good sealing performance, low cost and stable quality. Whether it is from the selection of raw materials or the technical indicators after the product is formed, it has won unanimous praise from customers.Stepped holes are machined on both ends of the roller steel tube for the stamping bearing seat, and then the bearing seat is press fitted.The main features of stamped bearing housings are:①A concave-convex labyrinth seal groove is directly designed on its outer side, and a layer of labyrinth seal structure is added to make the sealing effect more reliable. A sealing ring can be added to the outer end of the roller. A circular slope that is concave inward is designed on the sealing ring, and a labyrinth ring is raised when it is close to the circumference of the roller shaft, so that a sealing cover can be added. The gap with the roller shaft is changed from the traditional gap to an interference fit. The gap where the sealing cover and the sealing ring are embedded with each other is left inside the inwardly concave circular slope of the sealing ring. Since the gap is inverted, it effectively delays the tendency of water and ash to enter the sealed structure;②The moment of inertia is greatly reduced. The engineering plastic "nylon alloy" has a small specific gravity, which reduces the mass of the rotating part of the roller, and the moment of inertia is greatly reduced.③The mechanical strength of the engineering plastic "nylon alloy" can meet the requirements of the use of rollers, and can be produced by molds. The geometric dimensional accuracy and consistency are guaranteed, which provides a reliable guarantee for large-scale production.④Using the characteristics of plastic deformation of engineering plastic "nylon alloy", it can realize the production process of roller steel pipe without processing and assembling, ensuring the consistency of roller manufacturing accuracy.The rollers assembled with the new type of bearing housing are filled with appropriate grease in the labyrinth-type sealed cavity, and the water spray and dust-proof tests are performed on the simulated intensified test bench. The performance exceeds the standard and achieves the expected purpose.
