Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ceramic connectors, and more specifically to a high temperature resistant and wear resistant ceramic insert. Background Art
[0002] In the field of industrial production and mechanical manufacturing, components that work in high temperature and high wear environments are often required. Traditional insert structures often cannot meet the requirements of high temperature resistance and wear resistance at the same time.
[0003] Currently, most common inserts are simple columnar or block structures. These structures are prone to rapid decline in overall insert performance due to uniform heat transfer in high temperature environments, and lack effective structural design to disperse wear forces when facing friction and wear, resulting in more severe wear of the inserts. When used in conjunction with other components, simple geometric inserts have limited connection stability with other components and are prone to loosening or displacement under high temperature and high wear conditions. Utility Model Content
[0004] The utility model aims to provide a high temperature resistant and wear resistant ceramic insert, which improves the high temperature resistance and wear resistance, can obtain better connection stability, and reduce the possibility of loosening or displacement under high temperature and high wear conditions.
[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:
[0006] A high temperature and wear resistant ceramic insert comprises a ceramic body, one end of which is provided with an outwardly extending annular flange, the other end of which is provided with an inwardly recessed annular groove, and the outer surface of which is axially provided with spiral reinforcing ribs.
[0007] Furthermore, the cross-section of the reinforcing rib is semicircular.
[0008] Furthermore, the outer side surface of the annular flange is provided with a plurality of dovetail grooves evenly distributed axially around the ceramic body.
[0009] Furthermore, a plurality of positioning protrusions evenly distributed axially around the ceramic body are provided at the bottom of the annular groove.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] In this utility model, annular flanges and annular grooves are respectively arranged at both ends of the ceramic main body. This non - traditional simple columnar or block structure changes the heat transfer path. In a high - temperature environment, heat does not transfer evenly and quickly as in a common structure. Instead, complex transfer paths are formed at these special structural parts such as the annular flanges and annular grooves, slowing down the heat transfer speed, thereby improving the high - temperature resistance performance of the overall insert; the spiral reinforcing ribs arranged axially on the outer surface of the ceramic main body change the friction characteristics of the insert surface. When the insert rubs against other components, the spiral reinforcing ribs make the friction surface no longer a simple plane but a complex surface with a spiral structure. In this way, the frictional force can be dispersed, avoiding the concentration of wear forces in a certain area, thus reducing wear and improving the wear - resistance performance of the insert; the annular flanges can increase the contact area when connecting with other components, and the annular grooves can form a nested connection with other components. This design enables the insert to obtain better connection stability in both the axial and radial directions when used with other components, reducing the possibility of loosening or displacement under high - temperature and high - wear working conditions. Brief Description of the Drawings
[0012] Figure 1 It is a structural schematic diagram of this utility model.
[0013] 1. Ceramic main body; 2. Annular flange; 3. Annular groove; 4. Reinforcing rib; 5. Dovetail groove; 6. Positioning protrusion. Detailed Embodiment
[0014] As Figure 1 shown, a high - temperature - resistant and wear - resistant ceramic insert includes a ceramic main body 1. One end of the ceramic main body 1 is provided with an outward - extending annular flange 2, and the other end of the ceramic main body 1 is provided with an inward - recessed annular groove 3. The outer surface of the ceramic main body 1 is axially provided with spiral reinforcing ribs 4.
[0015] The cross - section of the reinforcing rib 4 is semi - circular; the cross - section of the reinforcing rib 4 being semi - circular makes the contact between the reinforcing rib 4 and other components smoother during the friction process. Compared with other cross - section shapes with distinct edges and corners, the semi - circular shape can reduce local stress concentration, thereby further reducing the possibility of wear and effectively improving the wear - resistance performance of the insert during use.
[0016] The outer side surface of the annular flange 2 is provided with a plurality of dovetail grooves 5 evenly distributed around the axis of the ceramic main body 1; when cooperating with other components, the dovetail grooves 5 can engage with corresponding structures on other components. After installation, this engaging structure can effectively prevent the insert from moving axially or radially during use, further enhancing the connection stability between the insert and other components.
[0017] A plurality of positioning protrusions 6 evenly distributed around the axis of the ceramic body 1 are provided at the bottom of the annular slot 3; a plurality of positioning protrusions 6 evenly distributed around the axis of the ceramic body 1 are provided at the bottom of the annular slot 3. When nested and connected with other components, these positioning protrusions 6 can match the corresponding structures on other components. Such a design makes the connection between the insert and other components at the slot part closer and more stable, effectively preventing the insert from detaching from the connection part under high-temperature and high-wear working conditions, and improving the reliability of the overall connection.
[0018] In the high-temperature environment of the present utility model, when heat is transferred to the high-temperature and wear-resistant ceramic insert, the annular flange 2 and the annular slot 3 on the ceramic body 1 change the path and speed of heat transfer, so that the heat will not quickly and evenly affect the entire insert, and the internal temperature rise speed is relatively slowed down; when relative movement occurs between the insert and other components to generate friction, the spiral reinforcing ribs 4 on the outer surface of the ceramic body 1 disperse the frictional force and avoid the concentration of wear force; when connecting with other components, the dovetail groove 5 of the annular flange 2 engages with the corresponding structure of other components, and the positioning protrusion 6 at the bottom of the annular slot 3 matches other components, ensuring the connection stability between the insert and other components from multiple parts.
[0019] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
