AI Technical Summary
During the working process, the traditional inner sleeve generates heat due to friction, which leads to a higher temperature and a larger volume, increasing friction and wear, thereby reducing equipment efficiency and increasing the frequency of failure.
A new inner sleeve was designed, with hanging ears on the sleeve, and an inclined heat dissipation hole was opened on the inner wall of the sleeve to connect with the sleeve holes to form a heat dissipation pipeline to effectively reduce heat accumulation.
Through the design of the heat dissipation hole, the inner sleeve can effectively control temperature changes, reduce friction and wear, reduce energy consumption and operating costs, and improve the stability and life of the equipment.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of mechanical parts and relates to an inner sleeve, in particular to a new inner sleeve. Background Art
[0002] Mechanical inner sleeves are usually installed inside parts that need to rotate or slide in mechanical equipment. Through their special materials and structural design, they can reduce friction, improve wear resistance, and enhance equipment stability. They are an indispensable part of the transmission system of mechanical equipment and have an important impact on the overall performance and life of the equipment.
[0003] The temperature of the traditional inner sleeve material gradually rises due to friction during operation. The inner sleeve expands and contracts due to heat, and its volume increases under the influence of heat. The increase in volume will reduce the gap between devices, causing the inner sleeve to be easily worn, with reduced efficiency and even frequent equipment failures during equipment operation. Summary of the invention
[0004] The utility model aims to provide a novel heat dissipation inner sleeve in view of the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a new type of inner sleeve, including a sleeve body, characterized in that the sleeve body is provided with hanging ears, the hanging ears are located on the left and right sides of the sleeve body, the sleeve body is provided with sleeve holes for easy installation, the top of the sleeve body is provided with a plurality of heat dissipation holes for connecting with the sleeve holes, and the heat dissipation holes are inclined, and the heat dissipation holes include an upper opening and a lower opening, the upper opening is provided at the top of the sleeve body, and the lower opening is connected with the sleeve holes.
[0006] In the above-mentioned novel inner sleeve, the hanging ear is provided with a mounting hole for facilitating the connection with the sleeve body.
[0007] Compared with the prior art, the new inner sleeve has heat dissipation holes connected to the outside world on the inner wall of the sleeve, which reduce the heat generated by the equipment when it is working, prevent the inner sleeve from increasing in volume due to heat, effectively reduce friction and wear, reduce energy consumption, and reduce operating costs.
