[0002] In modern mechanical transmission systems, sleeves are key components that are widely used for connection and support between various shafts and seats. However, under high load and high speed conditions, friction between the sleeve and the shaft easily generates a lot of heat, causing the sleeve temperature to rise, which in turn affects its service life and transmission efficiency. Traditional sleeve designs often lack effective heat dissipation mechanisms, making the sleeves easily damaged in high temperature environments, and even causing safety accidents.

[0026] For example, see Figure 1-Figure 8 The present invention provides a technical solution: a shaft sleeve with a cooling mechanism, comprising a shaft sleeve body 1, wherein the inner ring surface of the shaft sleeve body 1 is provided with two notches 2, a through hole 2 4 is provided between the two notches 2, through holes 1 3 are provided at both ends of the shaft sleeve body 1, two groups of through holes 1 3 are respectively connected to the two groups of notches 2, the notches 2 are annular grooves, a plurality of through holes 2 4 are provided, and the plurality of through holes 2 4 are distributed in a circle with the inner ring opening of the shaft sleeve body 1 as the central axis; a plurality of through holes 1 3 are provided in each group, and the plurality of through holes 1 3 are distributed in a circle with the inner ring opening of the shaft sleeve body 1 as the central axis.

[0027] When the sleeve body 1 is installed between the shaft seat and the shaft body, two notches 2 are reserved between the shaft body and the inner annular surface of the sleeve body 1. The heat generated by the sleeve body 1 and the shaft body is dissipated through convection formed by the through hole 1 3 and the through hole 2 4 on both sides of the notches 2, thereby achieving a cooling effect on the sleeve body 1 and the shaft body.

[0028] Embodiment 2, on the basis of embodiment 1, a wear-resistant sleeve 5 is sleeved on the tube body of the sleeve body 1, one end of the wear-resistant sleeve 5 is inserted in the slot 6, the slot 6 is provided on the surface of the sleeve body 1, a rubber ring 7 is fixed on the surface of the slot 6, the rubber ring 7 is a circular ring plate with an "L"-shaped cross-section, the rubber ring 7 is clamped between the wear-resistant sleeve 5 and the slot 6 to produce elastic deformation; a plurality of through holes 8 are provided on the surface of the slot 6, a screw 9 is inserted inside the through hole 8, one end of the screw 9 is fixed on the surface of the wear-resistant sleeve 5, and the other end of the screw 9 passes through the through hole 8 and is sleeved with a nut 10 threaded thereon.

[0029] A detachable wear-resistant sleeve 5 is installed on the outer side of the sleeve body 1, and the wear-resistant sleeve 5 realizes wear-resistant protection for the sleeve body 1. When the wear-resistant sleeve 5 or the sleeve body 1 is seriously worn, it is only necessary to replace the sleeve body 1 or the wear-resistant sleeve 5 separately, and there is no need to replace the entire sleeve body 1 and the wear-resistant sleeve 5. When assembling the sleeve body 1 and the wear-resistant sleeve 5, after the wear-resistant sleeve 5 is sleeved on the sleeve body 1, the screw 9 passes through the through hole 8, and then the nut 10 is sleeved on the screw 9 and screwed. The wear-resistant sleeve 5 clamps the rubber ring 7 to improve the screw connection firmness of the screw 9 and the nut 10.

[0030] Embodiment 3, on the basis of embodiment 2, a liquid collecting chamber 11 is reserved inside the wear-resistant sleeve 5, and the interior of the liquid collecting chamber 11 is filled with coolant, and pressure relief micropores 15 are provided on the end of the liquid collecting chamber 11 close to the screw 9 and on the rod body of the screw 9, and a sponge pad 16 is fixed to the end of the liquid collecting chamber 11 close to the screw 9, and the sponge pad 16 is an annular plate, and the sponge pad 16 covers the pressure relief micropores 15, and a reserved groove 17 is provided at the other end of the wear-resistant sleeve 5, and the reserved groove 17 is an annular groove, and the surface of the reserved groove 17 is plugged with a plug 12; a connecting plate 13 is fixed to the end of the plug 12 extending into the reserved groove 17, and the connecting plate 13 is an annular plate structure, and a plurality of fins 14 are integrally formed on the surface of the connecting plate 13, and the fins 14 are annular plates, and the sizes of the plurality of fins 14 are different, and the plurality of fins 14 are concentric circles.

[0031] After the wear-resistant sleeve 5 is sleeved on the sleeve body 1, it not only prevents the sleeve body 1 from wear, but also the inserted tube 12 inside the wear-resistant sleeve 5 extends outward to dissipate heat through the connecting plate 13 and the fins 14, which is beneficial to cooling the wear-resistant sleeve 5 and the sleeve body 1. After the coolant in the liquid collecting chamber 11 evaporates, the pressure is released through the pressure relief micropores 15. When the coolant needs to be supplemented, it will be removed and immersed in the coolant pool until the coolant extends into the liquid collecting chamber 11 through the pressure relief micropores 15.

[0032] Detailed usage process:

[0033] 1. Install the sleeve body

[0034] Check the sleeve body: Confirm the integrity of the sleeve body 1, including whether the notch 2, through hole 1 3 and through hole 2 4 on the inner ring surface are intact. Install the sleeve: Install the sleeve body 1 between the shaft seat and the shaft body, and ensure that two notches 2 are reserved between the shaft body and the inner ring surface of the sleeve body 1. Check the heat dissipation channel: Confirm whether the convection heat dissipation channel formed by through hole 1 3 and through hole 2 4 on both sides of the notch 2 between the sleeve body 1 and the shaft body is unobstructed.

[0035] 2. Install the wear-resistant sleeve

[0036] Prepare the wear sleeve: confirm the integrity of the wear sleeve 5, as well as whether the slot 6, rubber ring 7, through hole 8, screw 9 and nut 10 are complete. Install the wear sleeve: Sleeve the wear sleeve 5 on the sleeve body 1, and ensure that one end of the wear sleeve 5 is inserted into the slot 6. Fix the wear sleeve: After the screw 9 passes through the through hole 8, the nut 10 is screwed on the screw 9 to ensure that the wear sleeve 5 is firmly fixed on the sleeve body 1. Adjust the position of the rubber ring 7 so that it is clamped between the wear sleeve 5 and the slot 6 to produce elastic deformation and enhance the stability of the connection.

[0037] 3. Refill coolant (if applicable)

[0038] Check the liquid collecting chamber: If the wear-resistant sleeve 5 has a reserved liquid collecting chamber 11 inside and needs to be filled with coolant, please check whether the liquid collecting chamber 11 is intact and whether the pressure relief micropores 15 are covered by the sponge pad 16. Refill the coolant: If the coolant in the liquid collecting chamber 11 is insufficient, remove the wear-resistant sleeve 5 and soak it in the coolant pool until the coolant passes through the pressure relief micropores 15 and extends into the liquid collecting chamber 11. After ensuring that the coolant completely fills the liquid collecting chamber 11, reinstall the wear-resistant sleeve 5.

[0039] 4. Install the insert and dissipate heat Prepare the insert: Confirm whether the insert 12, connecting plate 13 and fin 14 are complete. Install the insert: Insert the insert 12 into the reserved groove 17 of the wear-resistant sleeve 5, and ensure that the connecting plate 13 and fin 14 are correctly installed. Dissipation operation: When the sleeve body 1 and the wear-resistant sleeve 5 are working, the heat dissipation effect of the connecting plate 13 and the fin 14 is used to cool the sleeve body 1 and the wear-resistant sleeve 5.

[0040] 5. Maintenance and Inspection Regular inspection: Regularly check the wear of the sleeve body 1 and the wear-resistant sleeve 5, and whether the heat dissipation channel is unobstructed.

[0041] Replacement of parts: If the sleeve body 1 or the wear-resistant sleeve 5 is severely worn, replace the corresponding parts separately according to the wear condition, without replacing the whole sleeve.

[0042] Replenishing coolant: Replenish the coolant in the liquid collecting chamber 11 regularly as needed to ensure the cooling effect.
