Description

Technical Field

[0001] This utility model relates to the field of bearing push rod technology, specifically a wear-resistant push rod for bearing equipment. Background Technology

[0002] In bearing processing, assembly, and operating equipment, the push rod is a key component for bearing positioning, support, and transmission adjustment. This refers to the wear-resistant push rod used in bearing equipment. During operation, the push rod needs to maintain contact with the bearing body for extended periods. It must withstand the load transmitted by the equipment to maintain the bearing's stable position and also allow for a certain degree of axial sliding according to operating conditions. Since bearing equipment often operates at high frequencies, the contact area between the push rod and the bearing body is prone to wear due to continuous friction. If the push rod's wear resistance is insufficient, it will directly affect the bearing's operating accuracy. Therefore, push rods with excellent wear resistance and stable support capabilities are required to ensure the long-term reliable operation of the bearing equipment.

[0003] Traditional push rods for bearing equipment often employ an integrated structural design or rely solely on simple plating to enhance wear resistance, which presents several drawbacks. Firstly, the integrated structure necessitates complete replacement after localized wear, increasing material costs and extending equipment downtime for maintenance. Secondly, simple plating offers limited wear resistance, and the coating easily peels off over time, leading to direct friction between the push rod and the bearing body, exacerbating wear on both. This, in turn, causes increased bearing vibration, decreased precision, and in severe cases, even equipment failure, impacting production efficiency and product quality. Therefore, we propose a wear-resistant push rod for bearing equipment. Utility Model Content

Positioning and fixing rings are provided on both sides of the bearing body, and the two positioning and fixing rings are fixedly connected by bolts. The push rod sleeve is fitted onto the push rod body, and the top end of the push rod sleeve is tightly fitted with the anti-wear sleeve.

[0007] The positioning and fixing components are arranged in multiple rings on the inner side of the wear-resistant sleeve, and are used to fix the connection between the wear-resistant sleeve and the bearing body.

[0008] Preferably, the top end of the push rod body is provided with a ring-shaped top ring, the outer cylindrical surface of the push rod body is provided with six annularly distributed guide grooves, and the inner wall of the anti-wear sleeve is provided with six annularly distributed guide sliders. The guide sliders slide in cooperation with the guide grooves, wherein one end of the anti-wear sleeve is tightly fitted with the end face of the top ring.

[0009] Preferably, the outer cylindrical surface of the anti-wear sleeve has eight annularly distributed positioning cavities on its inner side, and the positioning cavities extend to both ends of the anti-wear sleeve. A connecting positioning groove is formed between two adjacent positioning cavities. The connecting positioning groove is rectangular and has through connecting holes at both ends.

[0010] Preferably, the positioning and fixing assembly consists of a positioning end and an auxiliary spring. The bottom cylindrical surface of the positioning end is provided with positioning slides on both sides, and the bottom of the positioning end is provided with an auxiliary spring.

[0011] Preferably, the positioning end and the auxiliary spring are installed inside the positioning cavity, wherein the positioning slides on both sides of the bottom end of the positioning end pass through the two ends of the anti-wear sleeve and are slidably engaged, and the top end of the positioning end passes through the outer cylindrical surface of the anti-wear sleeve and is telescopically engaged.

[0012] Preferably, the inner ring of the bearing body has eight annularly distributed positioning holes on its inner wall, and the inner ring of the bearing body is sleeved on the outer cylindrical surface of the anti-wear sleeve, wherein the top end of the positioning end is fixedly connected to the positioning hole.

[0015] Compared with the prior art, this utility model provides a wear-resistant push rod for bearing equipment, which has the following beneficial effects:

[0016] 1. The bearing equipment uses a wear-resistant push rod, which directly contacts the bearing body through an anti-wear sleeve. This isolates the bearing body from direct friction with the push rod body, significantly reducing wear on both. Simultaneously, the sliding engagement between the guide groove of the push rod body and the guide slider of the anti-wear sleeve, as well as the engagement between the inner wall slide strip of the push rod sleeve and the guide groove, restricts relative rotation of components, ensuring stable axial sliding. Furthermore, the positioning of the anti-wear sleeve by the top ring and the initial fixation of the bearing body by the positioning and fixing components prevent additional wear due to displacement during operation, further enhancing the overall structural durability.

[0017] 2. This bearing equipment uses wear-resistant push rods, and the positioning and fixing ring is fixed by bolts passing through the wear-resistant sleeve and the positioning connecting piece. During disassembly, simply unscrew the bolts to remove the positioning and fixing ring. The bearing body is fixed by the positioning end and the positioning hole. Pressing the positioning end can release the fixation and remove the bearing body. The push rod sleeve is also connected to the push rod body by bolts. After removing the bolts, it can be slid off along the guide groove. The modular bolt fixing and elastic positioning structure allows the replacement of vulnerable parts such as the wear-resistant sleeve and bearing body without disassembling the whole unit, greatly improving maintenance efficiency.

[0046] Guide groove 11: Guide groove 11 consists of six annular grooves on the outer cylindrical surface of the push rod body 2, which can slide and engage with the guide slider 15 of the anti-wear sleeve 3 and the slide bar of the push rod sleeve 1; it can limit the relative rotation of the components and provide precise guidance for their axial sliding.

[0047] Top ring 12: Top ring 12 is a ring-shaped structure at the top of the push rod body 2, and its end face is tightly fitted with one end of the anti-wear sleeve 3; it can precisely limit the initial position of the anti-wear sleeve 3 on the push rod body 2 and avoid its axial over-displacement.

[0048] Positioning movable cavity 13: The positioning movable cavity 13 consists of eight annular cavities on the inner side of the outer cylindrical surface of the anti-wear sleeve 3, which penetrate both ends of the anti-wear sleeve 3; it provides installation space for the positioning end head 5 and the auxiliary spring 6, and ensures the stable operation of the positioning and fixing components;

[0049] Connecting positioning groove 14: Connecting positioning groove 14 is a rectangular groove between adjacent positioning movable cavities 13 on the wear-resistant sleeve 3, with through connecting holes at both ends; positioning connecting piece 10 can be inserted, and bolts can be used to connect positioning fixing ring 4 and wear-resistant sleeve 3.

[0050] Guide slider 15: The guide slider 15 consists of six annular protrusions on the inner wall of the wear-resistant sleeve 3, which slide in conjunction with the guide groove 11 of the push rod body 2; it can limit the relative rotation between the wear-resistant sleeve 3 and the push rod body 2, and ensure the axial sliding stability of the two.

[0051] Working principle: First, the anti-wear sleeve 3 is slidably fitted onto the outside of the push rod body 2. The outer cylindrical surface of the push rod body 2 has six annularly distributed guide grooves 11, while the inner wall of the anti-wear sleeve 3 has six annularly distributed guide sliders 15. The guide sliders 15 and the guide grooves 11 form a precise sliding fit, which not only restricts the relative rotation between the anti-wear sleeve 3 and the push rod body 2, but also ensures the stability of the two when sliding along the axial direction. At the same time, one end of the anti-wear sleeve 3 is tightly fitted with the end face of the annular top ring 12 at the top of the push rod body 2, further ensuring the anti-wear effect. The initial assembly position of the sleeve 3 on the push rod body 2 is followed by the assembly of the bearing body 7. The inner ring of the bearing body 7 is directly fitted onto the outer cylindrical surface of the anti-wear sleeve 3. To achieve a fixed connection between the bearing body 7 and the anti-wear sleeve 3, a positioning and fixing assembly is provided inside the anti-wear sleeve 3. The positioning and fixing assembly consists of a positioning end 5 and an auxiliary spring 6, and is arranged in multiple annular groups inside the anti-wear sleeve 3. Eight annularly distributed positioning movable cavities 13 are opened on the inner side of the outer cylindrical surface of the anti-wear sleeve 3. The positioning movable cavities 13 extend to both ends of the anti-wear sleeve 3. The positioning end 5 and auxiliary spring 6 are installed inside the positioning movable cavity 13. During assembly, the auxiliary spring 6 is in a compressed state, generating an upward elastic thrust on the positioning end 5. At the same time, the positioning slides 9 on both sides of the bottom cylindrical surface of the positioning end 5 pass through both ends of the anti-wear sleeve 3 and form a sliding fit, which not only restricts the movement direction of the positioning end 5, but also ensures its stable extension and retraction. When the inner ring of the bearing body 7 is sleeved on the outer cylindrical surface of the anti-wear sleeve 3, the eight annularly distributed positioning holes 8 on the inner wall of the inner ring of the bearing body 7 correspond exactly to the position of the positioning end 5. Under the elastic action of 6, the top end of the positioning end 5 passes through the outer cylindrical surface of the anti-wear sleeve 3 and is embedded in the positioning hole 8, realizing the initial fixed connection between the anti-wear sleeve 3 and the bearing body 7. In the positioning and fixing stage, in order to enhance the installation stability of the bearing body 7, it is necessary to perform secondary fixing through the positioning and fixing ring 4. The positioning and fixing ring 4 is in the shape of a ring, and its inner wall is provided with eight ring-shaped positioning connecting pieces 10. A rectangular connecting positioning groove 14 is opened between two adjacent positioning movable cavities 13 on the anti-wear sleeve 3. A through connecting hole is also opened at both ends of the connecting positioning groove 14.During assembly, two positioning and fixing rings 4 are respectively fitted onto the anti-wear sleeve 3 and located at both ends of the bearing body 7. At the same time, the positioning connecting piece 10 on the inner wall of the positioning and fixing ring 4 is precisely inserted into the connecting positioning groove 14 of the anti-wear sleeve 3. Then, bolts are used to pass through both ends of the anti-wear sleeve 3 and the positioning connecting piece 10. The positioning and fixing ring 4 and the anti-wear sleeve 3 are rigidly connected by bolt tightening, which can effectively limit the axial displacement of the bearing body 7 and prevent it from loosening due to vibration and other factors during operation. This further ensures the stability of the connection between the bearing body 7 and the anti-wear sleeve 3. Finally, in the sliding guide and overall limiting link, the assembly of the push rod sleeve 1 plays a key role. The push rod sleeve 1 is fitted onto the push rod body 2, and its inner wall is provided with six ring-shaped sliding strips. These sliding strips form a sliding fit with the guide groove 11 on the outer cylindrical surface of the push rod body 2, ensuring that the push rod sleeve 1 can slide stably along the push rod body 2. For position fixing, the end of the push rod sleeve 1 is fixedly connected to the end of the push rod body 2 by bolts. Simultaneously, the top surface of the push rod sleeve 1 is tightly fitted with the other end of the anti-wear sleeve 3, providing a final limit on the axial position of the anti-wear sleeve 3 on the push rod body 2, preventing the anti-wear sleeve 3 from falling off the push rod body 2. On the other hand, the tight fit between the push rod sleeve 1 and the anti-wear sleeve 3 also reduces the gap between them, lowering vibration and noise during operation. At the same time, the anti-wear sleeve 3 directly contacts the bearing body 7, reducing wear between the bearing body 7 and the push rod body 2, and extending the service life of the overall structure.
