Description

Technical Field

[0001] This utility model belongs to the field of large circular knitting machines, and in particular relates to an auxiliary installation component for a large disc gear. Background Technology

[0002] In large circular knitting machines, the large disc gear is the main transmission component. In current large circular knitting machines, the large disc gear is usually located in the large disc. To ensure the stable rotation of the large disc gear in the large disc, the large disc is usually equipped with limit blocks to limit the movement of the large disc gear, so that the central axes of the large disc and the large disc gear are coaxial.

[0003] A mounting structure for a large disc gear in a thread-pressing machine, application number CN201210045297.4, includes a large disc with an annular limiting boss. The large disc gear is positioned within the large disc and limited by the annular limiting boss. At least four bottom wear-resistant plates are arranged circumferentially on the contact surface between the bottom of the large disc gear and the inner bottom surface of the large disc. At least four side wear-resistant plates are arranged circumferentially on the contact surface between the inner wall of the large disc gear and the outer wall of the limiting boss. While the annular limiting boss limits the large disc gear, ensuring the coaxiality of the central axes of the large disc and the large disc gear requires adjustment of each limiting structure. Currently, this is done manually by feel, resulting in insufficient installation accuracy. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary mounting component for a large disc gear, so as to overcome at least one of the above-mentioned defects in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides an auxiliary installation component for a large disc gear, including a digital torque wrench, a connector, several adjusting components, and several limiting components. The digital torque wrench is detachably connected to the middle of the connector, the connector is detachably connected to the top of the large disc gear, several adjusting components are screwed to the inner wall of the large disc gear, and the ends of the adjusting components are provided with limiting components, the outer walls of the limiting components contacting the inner wall of the large disc gear.

[0007] Preferably, the adjusting component includes a first stud and a nut. The first stud is screwed to the inner wall of the large disc. The outer end of the first stud passes through the inner wall of the large disc and is rotatably connected to the limiting component. The inner end of the first stud is located inside the inner wall of the large disc and is screwed with a nut.

[0008] Preferably, the limiting component includes a limiting block and a second stud. The limiting block is rotatably connected to the first stud. The second stud is screwed to both sides of the limiting block. The bottom end of the second stud extends to the bottom of the limiting block and contacts the bottom wall of the large disc.

[0035] like Figures 1 to 8 As shown, this embodiment provides an auxiliary installation assembly for a large disc gear, including a digital torque wrench 1, a connecting member 2, several adjusting members 3, and several limiting members 4. In this embodiment, there are eight adjusting members 3 and eight limiting members 4, evenly spaced along the circumference of the large disc 5. The digital torque wrench 1 is detachably connected to the middle of the connecting member 2, which is detachably connected to the top of the large disc gear 6. Several adjusting members 3 are screwed to the inner wall of the large disc 5, and limiting members 4 are provided at the ends of the adjusting members 3. The outer wall of the limiting member 4 contacts the inner wall of the large disc gear 6. During installation, connector 2 is installed on top of the large disc 5. Then, the digital torque wrench 1 is placed on connector 2. Rotating the digital torque wrench 1 causes connector 2 to rotate, making the large disc 5 rotate. During this process, the large disc gear 6 is subjected to forces from the limiters 4 at different positions. The digital torque wrench 1 provides real-time feedback on the torque value during the rotation of the large disc 5. Based on the torque value, the installer adjusts the corresponding limiter 4 until the torque value remains constant during rotation. In this way, adjusting the position of the limiter 4 based on the torque value changes the traditional method of adjustment by feel, greatly improving installation accuracy. After all limiters 4 have been adjusted, the digital torque wrench 1 is removed, and connector 2 is detached from the large disc gear 6. Adjusting component 3 and limiters 4 are retained. The large disc gear 6 is limited by the limiters 4 at various positions, ensuring that the central axes of the large disc 5 and the large disc gear 6 are coaxial.

[0036] The adjusting component 3 includes a first stud 31 and a nut 32. The first stud 31 is screwed to the inner wall of the large disc 5. The outer end of the first stud 31 passes through the inner wall of the large disc 5 and is rotatably connected to the limiting component 4. The inner end of the first stud 31 is located inside the inner wall of the large disc 5 and is screwed with the nut 32. During adjustment, the first stud 31 is screwed on, causing the limiting component 4 to move closer to or away from the large disc gear 6. After adjustment, the nut 32 is screwed on to fix the position, keeping the limiting component 4 in its current position.

[0037] The limiting component 4 includes a limiting block 41 and a second stud 42. The limiting block 41 is rotatably connected to the first stud 31. Second studs 42 are screwed onto both opposite sides of the limiting block 41. The bottom end of the second stud 42 extends below the limiting block 41 and contacts the bottom wall of the large disc 5. The outer wall of the limiting block 41 contacts the inner wall of the large disc gear 6. The bottom surface of the second stud 42 is flat. The second stud 42 provides support for the limiting block 41, preventing it from rotating or shifting during adjustment. Its flat bottom surface ensures the levelness of the limiting block 41 and stable contact with the large disc gear 6. Furthermore, the screwing connection between the second stud 42 and the limiting block allows adjustment of the height of the limiting block 41, with the specific height adjustable according to requirements.

[0038] The first stud 31 has a ball head 311 at its outer end, and the inner wall of the limiting block 41 has a receiving groove 411. The ball head 311 extends into the receiving groove 411 and can rotate relative to the receiving groove 411. The rotational connection between the first stud 31 and the limiting block 41 is achieved through the cooperation of the ball head 311 and the receiving groove 411, ensuring that the first stud 31 smoothly pushes the limiting block 41 during adjustment without causing the limiting block 41 to rotate.

[0039] The outer wall of the limiting block 41 has an oil groove 412 that extends along the length of the limiting block 41. The oil groove 412 serves to store oil and lubricate the large disc gear 6 during operation.

[0040] The oil groove 412 is V-shaped, which allows the oil to stay in the oil groove 412 for a longer time, ensuring lubrication of the large disc gear 6.

[0041] The limiting block 41 includes a base 413 and a wear-resistant plate 414. The wear-resistant plate 414 is fixed to the outer wall of the base 413, and the outer wall of the wear-resistant plate 414 contacts the inner wall of the large disc gear 6. The wear-resistant plate 414 is used to prevent wear, thereby preventing the large disc gear 6 from shifting or vibrating during operation.

[0042] The connecting component 2 includes a horizontal arm 21, a first bolt 22, a second bolt 23, and a spacer 24. The first bolt 22 is screwed into the middle of the horizontal arm 21, and the socket of the digital torque wrench 1 mates with the head of the first bolt 22. Spacers 24 are installed at opposite ends of the horizontal arm 21 via the second bolt 23. The spacers 24 are located below the horizontal arm 21 and contact the top wall of the large disc gear 6. The bottom end of the second bolt 23 extends to the bottom of the spacer 24 and is screwed into the top wall of the large disc gear 6. The bottom surface of the spacer 24 is flat. By setting the spacers 24, the horizontal arm 21 is leveled, making the horizontal arm 21 parallel to the large disc gear 6, ensuring smooth rotation of the large disc gear 6.
