Description

Technical Field

[0001] The utility model belongs to the technical field of bearing seats, and in particular relates to an integrated sealed non-metallic bearing seat. Background Art

[0002] In the sewage treatment industry, the use of various mechanical equipment is crucial, including belt filter presses, plate and frame filter presses, mud scrapers, coarse screens, fine screens, etc. These equipment generally use bearing seats in the drive and transmission links to achieve their functions. At present, the standard practice in the industry is to use metal bearings and their matching bearing seats.

[0003] However, the sewage treatment environment has its own particularity. The complex components in the sewage, such as corrosive substances, high salinity, high temperature and exhaust gas, pose a severe challenge to the metal bearing seat. These environmental factors can easily damage the metal bearing seat and then corrode the bearing itself, resulting in a significant reduction in the durability of the equipment, thus shortening the service life of the equipment and increasing the cost of operation and maintenance.

[0004] Therefore, in order to improve the stability and reliability of equipment, reduce equipment failures caused by environmental factors, extend the service life of equipment, and control the operation and maintenance costs more reasonably economically, it is particularly important to develop and apply more suitable bearing and bearing seat materials for the special needs of the sewage treatment industry. This requires us to consider the complexity and corrosiveness of the sewage treatment environment in material selection and design, and ensure that the selected materials can effectively resist these harsh conditions to ensure the efficient operation of the entire sewage treatment system. Utility Model Content

[0005] The utility model aims to provide an integrated sealed non-metallic bearing seat, which is resistant to acid and alkali, chloride ions, sewage and exhaust gas erosion.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0007] An integrated sealed non-metallic bearing seat comprises a bearing seat body, a blind cover, a bearing, an oil seal and a sealing ring; the bearing seat body is provided with a blind cover mounting position, a bearing mounting position, an oil seal mounting position and a sealing ring combining position from the outside to the inside; the blind cover is connected to the bearing seat body by a thread to form a whole; the bearing is installed adjacent to the blind cover, and the blind cover ring presses the outer ring of the bearing to fix the bearing; the oil seal is installed adjacent to the bearing at the oil seal mounting position; the sealing ring is sleeved on the sealing ring combining position of the roller body and the bearing seat body.

[0008] Furthermore, the bearing seat body is also provided with an oil filling hole and a bolt fixing hole; the oil filling hole is arranged on the side of the bearing seat body and is installed with a standard oil cup so that the lubricating oil can be filled into the space formed by the blind cover, the bearing and the oil seal through the oil filling hole to form a sealing body, thereby protecting the bearing from gas and liquid erosion; the bolt fixing hole fixes the bearing seat body to the workpiece through bolts to prevent the bearing seat from shifting.

[0009] Furthermore, the sealing ring is provided with an inner ring and an outer ring; the inner ring is sleeved on the outer diameter of the roller body to form an interference fit; the outer ring is sleeved on the sealing ring combination position to form a clearance fit; the sealing ring and the roller body rotate synchronously, the inner ring is interference sealed, and the rotating outer ring and the bearing seat body form a dynamic seal at the sealing ring combination position to prevent sewage from entering and corroding the oil seal.

[0010] Furthermore, the connection between the blind cover and the bearing seat body is an external thread structure, and the blind cover is a polygonal structure (such as a quadrilateral or hexagon), which facilitates the installation and removal of the blind cover.

[0011] Furthermore, the bearing seat body is made of high-strength composite HPPA material through precision injection molding and has a hollow skeleton structure to ensure strength while reducing weight.

[0012] The beneficial effects of the utility model are as follows: the one-piece sealed non-metallic bearing seat of the utility model adopts an one-piece design, which simplifies the installation process and improves the maintenance efficiency. The non-metallic bearing seat adopts high-strength composite HPPA material to improve the acid, alkali and chloride ion resistance of the bearing seat, and can adapt to the sewage corrosive environment. The special structure of the one-piece sealed non-metallic bearing seat can prevent sewage and exhaust gas erosion, provide better sealing performance, and protect the bearing from external pollution. The weight of the bearing seat is reduced, and the overall burden of the equipment is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
