Description

Technical Field

[0001] This utility model belongs to the technical field of wire doffing machine components, and in particular relates to an easy-to-maintain drive driven wheel. Background Technology

[0002] The driven wheel of the doffing machine is the core component of its drafting transmission system. It is not directly connected to the power source but is driven to rotate by the driving wheel. Its main function is to precisely guide and transmit the filament bundle, and to apply drafting force through the speed difference with the front and rear wheel sets, thereby increasing fiber strength. It is also responsible for changing the filament bundle direction, providing contact pressure, and maintaining stable filament bundle tension. These are crucial for ensuring the quality of chemical fiber products. However, the driven wheel of the doffing machine still has the following drawbacks in actual use: During the operation and maintenance of the driven wheel of the doffing machine, after a long period of operation, the wheel body is prone to the accumulation of oil, dust and other impurities on the driven wheel due to the oil and dust on the yarn bundle. It is necessary to remove the driven wheel. When removing the driven wheel, the bolts are fastened to the mounting structure, and rotation will drive the driven wheel to rotate, which is not convenient for disassembly. Secondly, during maintenance, the driven wheel of the wire doffing machine is directly installed using an installation device. During installation, the driven wheel structure needs to be aligned with the installation structure, and the operator needs to tighten it. Therefore, the installation and positioning are not convenient during operation. Utility Model Content

[0003] The purpose of this utility model is to provide an easy-to-maintain drive driven wheel. By setting a fixed chamber, a movable rod, a driven bearing, and a limiting component, it solves the problems that the drive driven wheel of the wire doffing machine is not easy to disassemble during maintenance, and is not easy to reinstall and position after disassembling the driven wheel.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an easy-to-maintain driven wheel, comprising a fixed chamber, movable rods, a driven bearing, and a limiting assembly. Movable holes are provided on both lower sides of the fixed chamber, and movable rods are movably connected to each of the two movable holes. A driven bearing is movably connected between the two movable rods, and the driven bearing is located in the lower part of the fixed chamber. Limiting assemblies are symmetrically fixed at the top of the fixed chamber, and each limiting assembly includes a limiting roller. The fixed chamber serves as the main structure, with movable holes on both lower sides for the movable rods to pass through. The movable rods connect to and support the driven bearing located in the lower part of the fixed chamber. The limiting assemblies are symmetrically installed at the top of the fixed chamber, and the limiting rollers constrain the position of the outer ring of the driven bearing, ensuring that it does not deviate during operation.

[0005] Furthermore, mounting screw holes are symmetrically provided below the movable holes on both sides of the fixed chamber, and mounting brackets are fixed to the upper part of both ends of the fixed chamber. The fixed chamber has symmetrical mounting screw holes below the movable holes, and mounting brackets are fixed to the upper part of both ends, so that the entire fixed chamber can be installed to the bottom of the wire drawing machine by bolts.

[0006] Furthermore, a limiting plate is fixed to the end of the movable rod away from the driven bearing. The limiting plate is located outside the fixed chamber. The outer end of the movable rod is provided with a limiting plate located outside the fixed chamber to prevent the movable rod from moving excessively inward, thereby limiting the relative position of the movable rod and the fixed chamber.

[0007] Furthermore, a connecting cantilever is symmetrically fixed to the lower part of the movable rod between the inner wall of the fixed chamber and the driven bearing. A mounting bolt is threaded into each of the two mounting screw holes. The mounting bolt is rotatably connected to the side of the connecting cantilever away from the driven bearing. A connecting cantilever is fixed on the movable rod. The mounting bolt passes through the mounting screw hole and is rotatably connected to the connecting cantilever. By tightening or loosening the mounting bolt, the movable rod can be pushed or pulled back to realize the installation, fixation or disassembly of the driven bearing.

[0008] Furthermore, a fixed sleeve is fixed to the periphery of the driven bearing, and an outer ring is fixed to the periphery of the fixed sleeve. A limit ring is fixed to one edge of the periphery of the outer ring. The driven bearing is fitted with a fixed sleeve, and the outer ring is fixed on the fixed sleeve. A limit ring is provided on one side of the outer ring. The outer ring is used for rolling and conveying on the track, and the limit ring plays a guiding role for the filament bundle to prevent the filament bundle from falling off.

[0009] Furthermore, the limiting assembly also includes connecting rods. The two limiting rollers respectively contact the upper part of the outer circumference of the outer ring. Connecting rods are fixed at both ends of the limiting rollers. The top ends of the connecting rods at both ends of the limiting rollers are fixed to the top of the fixed chamber. The limiting rollers are fixed to the top of the fixed chamber through the connecting rods at both ends. Their wheel surfaces contact the upper part of the outer ring to limit the vertical movement of the outer ring and ensure that the driven bearing operates stably in the fixed chamber.

[0010] This utility model has the following beneficial effects: This invention solves the problem of inconvenient disassembly of the driven wheel of the wire doffing machine during maintenance by setting up a fixed chamber, a movable rod, and a driven bearing. When it is necessary to remove the driven bearing from the fixed chamber, simply rotate the mounting bolt to pull the movable rod out of the driven bearing. Then, pull the driven bearing, the fixed sleeve, and the outer wheel ring to remove the driven bearing from the fixed chamber, thus completing the disassembly of the driven bearing. This makes the disassembly of the driven wheel of the wire doffing machine more convenient during maintenance.

[0011] This invention solves the problem of inconvenient reinstallation and positioning of the driven wheel of the doffing machine after disassembly by setting up a fixed chamber, a movable rod, a driven bearing, and a limiting component. During the installation of the driven bearing in the fixed chamber, the direction of the upper limiting ring on the outer ring of the driven bearing is first determined. The driven bearing, fixed sleeve, outer ring, and limiting ring are then placed in the fixed chamber and their positions are determined with the two limiting rollers. This facilitates the alignment of the driven bearing with the movable rod, making it easier to reinstall and position the driven wheel of the doffing machine after disassembly.

Specific Implementation Example 1

[0016] Please see Figure 1-6 This utility model is an easy-to-maintain driven wheel, including a fixed chamber 1, a movable rod 2, a driven bearing 3, and a limiting component 4. The lower parts of both sides of the fixed chamber 1 are provided with movable holes 101, through which the driven bearing 3 is connected. The fixed chamber 1 is movably connected to the movable rod 2 through the movable holes 101. The movable rod 2 is movably connected in both movable holes 101. The movable rod 2 is connected to the driven bearing 3 in the fixed chamber 1. The driven bearing 3 is movably connected between the two movable rods 2. The driven bearing 3 is located in the lower part of the fixed chamber 1. The driven bearing 3 cooperates to connect the roller to it. The limiting component 4 is symmetrically fixed in the top of the fixed chamber 1. The limiting component 4 includes a limiting roller 401. The limiting component 4 limits and determines the position of the outer wheel rim 302 in the fixed chamber 1.

[0017] Specifically, mounting screw holes 102 are symmetrically provided below the movable holes 101 on both sides of the fixed chamber 1. Mounting brackets 103 are fixed to the upper part of both ends of the fixed chamber 1. The fixed chamber 1 is connected to the mounting bolts 203 through the mounting screw holes 102. The mounting bolts are screwed into the bottom of the wire drawing machine after passing through the mounting brackets 103. The fixed chamber 1 is then installed between the fixed chamber 1 and the wire drawing machine.

[0018] Furthermore, a limiting plate 201 is fixed at the end of the movable rod 2 away from the driven bearing 3. The limiting plate 201 is located on the outside of the fixed chamber 1 and is used to limit the extreme position of the movable rod 2 moving inward to the inside of the fixed chamber 1.

[0019] Furthermore, a connecting cantilever 202 is symmetrically fixed to the lower part of the periphery of the movable rod 2 between the inner wall of the fixed chamber 1 and the driven bearing 3. A mounting bolt 203 is threaded into each of the two mounting screw holes 102. The mounting bolt 203 is rotatably connected to the side of the connecting cantilever 202 away from the driven bearing 3. The movable rod 2 is rotatably connected to the mounting bolt 203 through the connecting cantilever 202. The mounting bolt 203 is threadedly connected to the mounting screw hole 102 of the fixed chamber 1. After rotating the mounting bolt 203, the movable rod 2 is driven to change position.

[0020] Furthermore, a fixed sleeve 301 is fixed to the periphery of the driven bearing 3, and an outer ring 302 is fixed to the periphery of the fixed sleeve 301. A limit ring 303 is fixed to one edge of the periphery of the outer ring 302. The driven bearing 3 is connected to the outer ring 302 through the fixed sleeve 301. The outer ring 302 guides and conveys the falling filament bundle. The limit ring 303 is used to guide the filament bundle and prevent it from detaching from the outer ring 302.

[0021] The operation process of this embodiment is as follows: When it is necessary to install and limit the driven bearing 3 during operation, after the driven bearing 3 is placed into the fixed chamber 1 and limited, the mounting bolt 203 is rotated. During the rotation of the mounting bolt 203, the movable rod 2 is driven to move until the movable rod 2 is inserted into the driven bearing 3. After the mounting bolt 203 is tightened between the fixed chamber 1, the driven bearing 3 is installed in the fixed chamber 1. When it is necessary to remove the driven bearing 3 from the fixed chamber 1, the mounting bolt 203 is rotated directly to drive the movable rod 2 out of the driven bearing 3. Then, the driven bearing 3, the fixed sleeve 301 and the outer ring 302 are pulled to remove the driven bearing 3 from the fixed chamber 1, thus completing the disassembly of the driven bearing 3.
