Abstract
Description
A special tool for quick disassembly and assembly of belt conveyor roller bearings Technical Field
[0001] This utility model relates to the field of mechanical technology, and in particular to a special tool for quick disassembly and assembly of belt conveyor roller bearings. Background Technology
[0002] As a crucial material conveying equipment in modern industrial production, the reliability of the roller bearings in belt conveyors directly affects the equipment's operating efficiency and service life. During equipment maintenance, the disassembly and assembly of roller bearings is a common and critical operation. Traditional disassembly and assembly methods typically rely on manual operation with simple tools, which can lead to inaccurate positioning and uneven force distribution, easily causing bearing damage or installation misalignment, and consequently resulting in abnormal equipment vibration, accelerated wear, and other malfunctions.
[0003] In existing technologies, the disassembly and assembly of belt conveyor roller bearings generally employs general-purpose tools combined with hammering and prying. However, such methods have significant drawbacks: on the one hand, the impact force generated by hammering can easily cause deformation of the inner and outer rings of the bearing or damage to the raceway, reducing the bearing's precision; on the other hand, manual prying makes it difficult to precisely control the applied force angle and clamping range, which can easily lead to scratches on the mating surfaces of the bearing and the journal, and even cause installation tilting. Summary of the Invention
[0004] This utility model discloses a special tool with a compact structure, convenient operation, and effective protection for bearings, in order to meet the needs of efficient and safe disassembly and assembly.
[0005] The technical solution adopted by this utility model is as follows: a special tool for quick disassembly and assembly of belt conveyor roller bearings, including a fixing plate, side plates fixedly connected to the bottom of both ends of the fixing plate, a telescopic rod fixedly connected to the bottom of the middle of the fixing plate, a stop block fixedly connected to the movable end of the telescopic rod, and a bearing clamping mechanism provided at the lower part of both side plates. The bearing clamping mechanism includes a screw that passes through the side plate and is threadedly connected to it. A clamping element is rotatably connected to the end of the screw near the stop block, and a knob is fixedly connected to the end of the screw away from the stop block.
[0006] As a further improvement of this utility model, handles are fixedly connected to the top of both ends of the fixing plate.
[0007] As a further improvement of this utility model, the screw is rotatably connected to the clamping member through a bearing.
[0008] As a further improvement of this utility model, the clamping member is fixedly connected to two guide posts that pass through the side plate on the side away from the abutment block, and the side plate is provided with guide holes for the guide posts to pass through.
[0009] As a further improvement of this utility model, the clamping member has a semi-arc structure.
[0010] The beneficial effects of this utility model are as follows: This utility model sets up an adjustable bearing clamping mechanism and a telescopic rod to work together. The screw drives the semi-arc clamping part to form a uniform covering and clamping of the bearing. At the same time, the telescopic rod pushes the abutment block to apply an axial thrust, thereby realizing the rapid separation of the bearing from the journal. Attached Figure Description

[0015] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.
[0016] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.
[0017] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0018] This utility model provides a special tool for quick disassembly and assembly of belt conveyor roller bearings, as shown in Figures 1-3. It includes a fixed plate 1, with side plates 2 fixedly connected to the bottom of both ends of the fixed plate 1. A telescopic rod 3 is fixedly connected to the bottom of the middle of the fixed plate 1. A stop block 4 is fixedly connected to the movable end of the telescopic rod 3. Bearing clamping mechanisms are provided at the lower part of both side plates 2. The bearing clamping mechanism includes a screw 5 that passes through the side plate 2 and is threadedly connected to it. A clamping element 6 is rotatably connected to the end of the screw 5 near the stop block 4. A knob 7 is fixedly connected to the end of the screw 5 away from the stop block 4.
[0019] As shown in Figure 1, in this utility model, handles 8 are fixedly connected to the top of both ends of the fixed plate 1, which allows the operator to easily hold and use the entire tool.
[0020] As shown in Figures 1-3, in this invention, the screw 5 is rotatably connected to the clamping member 6 via the bearing 9. Two guide posts 10, passing through the side plate 2, are fixedly connected to the side of the clamping member 6 away from the abutment block 4. The side plate 2 has guide holes through which the guide posts 10 pass. The clamping member 6 has a semi-arc structure, which better conforms to the shape of the bearing, improving the stability and reliability of the clamping.
[0021] Working Principle: In practical implementation, the tool is first placed at the location of the conveyor roller bearing to be disassembled or installed. The operator holds the handle 8 and places the fixing plate 1 in a suitable position, so that the two side plates 2 are located on both sides of the bearing. Then, by rotating the knob 7, the screw 5 is driven to rotate. Since the screw 5 is threadedly connected to the side plate 2, when the screw 5 rotates, it moves along the threaded hole of the side plate 2 towards the abutment 4, thereby pushing the clamping member 6 closer to the bearing. Because the clamping member 6 has a semi-arc structure, as the screw 5 advances, the two semi-arc clamping members 6 gradually and evenly cover and clamp the bearing. At this time, the telescopic rod 3 is operated to extend its movable end, pushing the abutment 4 to apply an axial pushing force towards the journal. Under the combined action of the stable clamping of the clamping member 6 and the axial pushing force of the abutment 4, the bearing is quickly separated from or installed from the journal.
[0022] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
