Abstract
Description
Technical Field
[0001] This utility model relates to the disassembly of bearings of screw conveyors used in the papermaking and pulping industry, and in particular to an adjustable screw conveyor bearing device. Background Technology
[0002] Currently, screw conveyors are the main equipment used by paper mills for transporting pulp in my country's paper pulping industry. During operation, the screw shaft requires bearings to be mounted on bearing housings and fixed to the screw conveyor. Due to the heavy load and harsh working conditions of pulping equipment, the lifespan of the screw shaft is shortened, necessitating disassembly, maintenance, and replacement. The existing bearing housing mounting method makes it difficult to remove the lower bearing housing from the support plate, thus creating difficulties for the maintenance and replacement of the bearings and screw shaft. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide an adjustable screw conveyor bearing device with large disassembly space, repeated disassembly and assembly, high positioning accuracy, and reliable fixing.
[0004] To solve the above-mentioned technical problems, the adjustable screw conveyor bearing device of this utility model includes a bearing seat for fixing the bearing, a detachable adjusting seat, and a bottom support plate located at the bottom. The adjusting seat is arranged between the bearing seat and the bottom support plate. The adjusting seat includes an upper pad, a lower pad, and a channel steel located between the upper pad and the lower pad. The adjusting seat is installed on the bottom support plate and fixed by threaded fasteners.
[0005] Both the upper and lower pads are welded onto the channel steel.
[0006] The adjusting seat and the bearing seat are connected by threaded fasteners.
[0007] The bottom support plate has multiple mounting holes arranged in a matrix for inserting threaded fasteners.
[0008] The bottom support plate is provided with a side reinforcement plate.
[0009] The channel steel has a hollow structure.
[0010] The bearing housing is provided with a weight-reducing groove.
[0011] The bearing is a self-aligning roller bearing.
[0012] Advantages of this utility model: 1. The adjusting seat is a structure welded together by an upper pad, a lower pad, and a channel steel in the middle. The channel steel is a common type of steel material with universal specifications and wide availability. It is convenient to obtain materials and process them on-site according to the specific working conditions of different screw conveyors, which effectively reduces the difficulty of parts processing and manufacturing costs, and improves the applicability of the device. 2. The upper and lower pads are welded to both ends of the channel steel, so that the adjusting seat forms a stable frame structure. Even if the channel steel is a hollow structure, it can effectively bear the radial and axial loads generated by the bearing during operation, avoid the problem of easy deformation of a single pad structure, and improve the overall rigidity and long-term stability of the bearing installation part. 3. By setting the adjusting seat between the bearing housing and the bottom support plate and connecting it with threaded fasteners, the bearing housing can be stably fixed while the bearing housing can be replaced to achieve fine adjustment of the bearing installation height according to the installation requirements of different screw conveyors or different working conditions. The multiple mounting holes on the bottom support plate can be used to achieve a tight connection of the adjusting seat position, and there is enough space for disassembly and assembly, which is convenient for the maintenance, replacement and reuse of the bearing. 4. Side reinforcement plates are installed on the sides of the bottom support plate to form a multi-directional force support structure for the bearing device during the operation of the screw conveyor. This effectively enhances the connection strength between the bearing device and the machine body, reduces the impact of operating vibration on the bearing seat and adjustment seat, and improves the vibration resistance and reliability of the overall structure.

Detailed Implementation
[0014] The adjustable screw conveyor bearing device of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example
[0015] like Figures 1-5As shown, the adjustable screw conveyor bearing assembly includes a bearing housing 1 for fixing the bearing, a detachable adjusting seat 2, and a bottom support plate 6 located at the bottom. The adjusting seat 2 is positioned between the bearing housing 1 and the bottom support plate 6. The adjusting seat 2 includes an upper pad 3, a lower pad 4, and a channel steel 5 located between the upper pad 3 and the lower pad 4. The upper pad 3 and the lower pad 4 are welded and fixed to the upper and lower surfaces of the channel steel 5, respectively, forming an integral structure for the adjusting seat 2. The channel steel 5 is a hollow structure, which facilitates on-site material sourcing and processing, while reducing the overall weight while ensuring structural strength. The bearing housing 1 is detachably mounted on the upper pad 3 using threaded fasteners, and the bottom support plate... 6 is connected and fixed to the lower support plate 4 by threaded fasteners. The bottom support plate 6 has several evenly distributed mounting holes 7 for inserting threaded fasteners, thereby tightening the adjusting seat 2 and the bottom support plate 6 and adjusting the relative position between the adjusting seat 2 and the bottom support plate 6. The side of the bottom support plate 6 is provided with a side reinforcement plate 9, which is used to improve the overall structural strength after the bearing device is connected to the screw conveyor body, and enhance the vibration resistance and stability of the bearing device during operation. The bearing seat 1 is provided with a weight reduction groove 8 inside, which reduces its own weight while ensuring the bearing capacity of the bearing seat 1. The bearing seat 1 is equipped with a self-aligning roller bearing.
[0016] During installation, first fix the adjusting seat 2 to the bottom support plate 6 using threaded fasteners, then fix the bearing seat 1 to the upper pad 3 of the adjusting seat 2. The adjusting seat 2 is fixed in the mounting hole of the bottom support plate 6, which can be used to meet the bearing installation requirements of screw conveyors of different specifications.
