Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of screw conveyor bearing protection devices, specifically a screw conveyor bearing protection device. Background Technology
[0002] Screw conveyors are widely used in industrial production for horizontal or inclined conveying of powdery, granular, and small lump materials. Bearings are installed to facilitate the rotation of the main shaft, supporting it for screw conveying. However, in dusty environments, particles can easily enter the bearings, leading to severe wear and a short service life, thus presenting certain shortcomings. Therefore, we propose a bearing protection device for screw conveyors. Utility Model Content
[0003] The present invention aims to solve the problems existing in the prior art or related technologies.
[0004] Therefore, the technical solution adopted by this utility model is as follows: a bearing protection device for a screw conveyor, comprising a bearing housing, a lower protective shell, and an upper protective shell. An annular groove is provided on the outside of the bearing housing. The lower protective shell is inserted into the bearing housing. A sealing ring is provided at the top of the lower protective shell. A stud is provided at the top of the lower protective shell, and a fastening knob is threaded onto the stud. The upper protective shell is hinged to the top of the lower protective shell. Both the upper and lower protective shells are provided with locking blocks for engaging. Several baffles for sealing are provided on the inner sides of both the upper and lower protective shells.
[0005] Preferably, the bearing housing is rotatably connected to the main shaft of the screw conveyor via a bearing.
[0006] Preferably, the sealing ring is strip-shaped, and two sealing rings are symmetrically distributed on the lower protective shell.
[0007] Preferably, both the upper and lower protective shells are provided with rotating holes for the rotation of the screw conveyor main shaft, and the diameter of the rotating holes is larger than that of the screw conveyor main shaft.
[0008] Preferably, the right side of the upper protective shell has an insertion hole for fixing the stud, and the right side of the insertion hole is open.
[0009] Preferably, it also includes a desiccant, which is disposed inside the lower protective shell.
[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: By setting a lower protective shell and an upper protective shell, this utility model achieves a sealing effect without affecting the use of the screw conveyor main shaft, preventing external particles from wearing the bearing, extending its service life, and facilitating disassembly and assembly. Simultaneously, the inclusion of a desiccant provides a moisture-proof effect. During use, the user can align the locking blocks on the lower and upper protective shells with the annular groove on the bearing seat and insert them. After insertion, rotating the lower or upper protective shell causes it to close. Once closed, the stud will be inserted into the insertion hole of the upper protective shell. Then, rotating the fastening knob secures it for easy disassembly and assembly. After securing, the lower or upper protective shell seals the bearing inside the bearing seat, preventing external particles and other foreign objects from wearing the bearing. The sealing ring prevents foreign objects from entering through the gap between the lower and upper protective shells, while the baffle prevents foreign objects from entering through the rotating hole, improving sealing performance and facilitating use. Furthermore, a desiccant can be placed inside the lower protective shell; after placement, the desiccant absorbs moisture, delaying bearing corrosion and extending its service life.

[0023] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a screw conveyor bearing protection device, including a bearing housing 100, a lower protective shell 200 and an upper protective shell 300.
[0024] Specifically, the bearing housing 100 has an annular groove 101 on its outside. The bearing housing 100 is rotatably connected to the main shaft of the screw conveyor through a bearing. In use, the bearing housing 100 is used to install the bearing, and the annular groove 101 facilitates the installation of the lower protective shell 200 and the upper protective shell 300.
[0025] Specifically, the lower protective shell 200 is inserted into the bearing housing 100. A sealing ring 203 is provided at the top of the lower protective shell 200. The sealing ring 203 is strip-shaped, and two sealing rings 203 are symmetrically distributed on the lower protective shell 200. A stud 205 is provided at the top of the lower protective shell 200, and a fastening knob 206 is threaded onto the stud 205. In use, the sealing ring 203 improves the sealing performance of the device. The cooperation between the stud 205 and the fastening knob 206 can fix the upper protective shell 300 onto the lower protective shell 200 for disassembly of the device.
