Description

Technical Field

[0001] The utility model relates to the technical field of bearing installation, and specifically relates to a bearing that is convenient to install. Background Art

[0002] In modern mechanical equipment, bearings are indispensable key components. The main function of a bearing is to support a mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. Through the support and guidance of the bearing, mechanical equipment can operate efficiently and stably, thereby meeting various complex process requirements. Widely used in various transmission systems, bearings can ensure the smooth operation of rotating components, reduce energy loss and wear.

[0003] However, during the installation process of traditional bearings, the installation of balls often requires relatively complex operations and precise positioning and fixing with the aid of special tools. This not only increases the installation difficulty but also prolongs the installation time, resulting in an increase in installation costs. In view of the above problems, a bearing that is convenient to install is thus proposed. Content of the Utility Model

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a bearing that is convenient to install.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A bearing that is convenient to install, including an outer bearing ring. One side of the inner surface of the outer bearing ring is provided with an inclined groove. A ball is movably connected to the center inside the outer bearing ring. A guiding groove is provided on the outer surface of the inclined groove. A fixed seat is fixedly connected to the inner surface of the top end of the guiding groove. An expansion rod is movably connected to the outer side of the top of the fixed seat. A spring is arranged on the outer circle of the expansion rod. One side of the outer surface of the spring is fixedly connected to a guiding tube. A limiting groove is arranged on one side inside the guiding tube.

[0006] As described above, the inclined groove is provided between the limiting groove and the outer bearing ring. One side outer wall of the ball is rotationally connected to the inner surface of the outer bearing ring through the limiting groove. The guiding grooves are annularly distributed on the outer surface of the inclined groove.

[0007] As described above, the spring is coated outside the expansion rod. Both the expansion rod and the spring are fixed between the guiding tube and the fixed seat. The other side bottom end of the guiding tube is rotationally connected to the inner wall of the bottom side of the guiding groove. The guiding tube and the inner side of the guiding groove form a telescopic structure through the cooperation of the expansion rod and the spring.

[0008] As described above, a cage is movably connected to the outer surface of the ball. A clamping ring is fixedly connected to one side of the outside of the cage. A connecting block is fixedly connected to the inner surface of the clamping ring. A vibration isolation layer is fixedly connected to the inner surface of the connecting block. A fixing bolt is movably connected to the other side of the outside of the cage. The inner surface of the ball is movably connected to an inner bearing ring.

[0009] As described above, the cage is snap-fitted with the ball through the clamping ring. A number of connecting blocks are provided. The vibration isolation layer is made of silica gel. The inner surface of the vibration isolation layer is closely attached to the outer surface of the ball.

[0010] As described above, the outer wall of the other side of the ball is rotatably connected to the surface of the inner bearing ring. The ball is rotatably connected between the inner bearing ring and the outer bearing ring.

[0011] As described above, a set of cages is provided. The cages are symmetrically distributed at the upper and lower ends of the ball. The set of cages is fixedly connected by fixing bolts.

[0012] Compared with the prior art, the convenient-to-install bearing has the following beneficial effects:

[0013] First, when the present utility model is installed, the ball is pushed into the inside of the outer bearing ring along the direction of the inclined groove. During the process of the ball entering the inclined groove, it will slide along the guiding groove on the inclined groove. As the ball is further pushed in, the ball will contact the guiding tube in the guiding groove. At this time, the telescopic rod and the spring at the bottom of the guiding tube will be compressed inward under the action of the ball, driving the guiding tube inward, so that the ball smoothly enters the internal limiting groove along the guiding tube. After the ball completely enters the limiting groove, the elastic force of the spring and the telescopic rod will make the guiding tube return to the initial position. At this time, the guiding tube rebounds outward, and the top of the guiding tube restricts the ball in the limiting groove, preventing the ball from sliding out along the guiding groove. The guiding groove and the guiding tube make the installation process of the ball simple and fast, and at the same time ensure the accuracy of the position of the ball. At the same time, since the ball is restricted by the guiding tube and the limiting groove, its position is relatively stable and not easy to fall off, thus ensuring the stability of the bearing during use.

[0014] Second, after the ball of the present utility model is placed at the center of the inside of the outer bearing ring, ensure that the ball can rotate freely. Then place the cage on the outer surface of the ball, and tightly snap-fit the cage with the ball through the clamping ring. At the same time, ensure that the vibration isolation layer on the inner surface of the connecting block is closely attached to the outer surface of the ball. By using the vibration isolation layer made of silica gel to reduce the impact force and vibration amplitude during the operation of the bearing, so as to improve the vibration isolation effect. Subsequently, place the inner bearing ring on one side of the inside of the ball, ensure that the ball can rotate freely between the inner bearing ring and the outer bearing ring. Finally, use fixing bolts to fix a set of cages together to complete the installation of the bearing.

[0015] Other advantages, objects and features of the present utility model will be set forth in part in the following description, and in part will be obvious to those skilled in the art upon examination of the following, or may be learned from the practice of the present utility model.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-4As shown in the figure, the utility model provides a technical solution: a bearing that is convenient to install, including an outer bearing ring 1. On one side of the inner surface of the outer bearing ring 1, an inclined groove 101 is provided. At the center inside the outer bearing ring 1, a ball 102 is movably connected. On the outer surface of the inclined groove 101, a guiding groove 2 is provided. At the inner surface of the top of the guiding groove 2, a fixing seat 201 is fixedly connected. On the outer side of the top of the fixing seat 201, a telescopic rod 202 is movably connected. A spring 203 is arranged on the outer ring of the telescopic rod 202. On the outer surface of one side of the spring 203, a guiding tube 204 is fixedly connected. On one side inside the guiding tube 204, a limiting groove 205 is provided. The outer surface of the ball 102 is movably connected with a cage 3. On the outer side of one side of the cage 3, a clamping ring 301 is fixedly connected. On the inner surface of the clamping ring 301, a connecting block 302 is fixedly connected. On the inner surface of the connecting block 302, a vibration isolation layer 303 is fixedly connected. On the outer side of the other side of the cage 3, a fixing bolt 304 is movably connected. The inner surface of the ball 102 is movably connected with an inner bearing ring 305.

[0023] According to the overall structure of the device, during installation, the ball 102 is pushed into the inside of the outer bearing ring 1 along the direction of the inclined groove 101. During the process of the ball 102 entering the inclined groove 101, it will slide along the guiding groove 2 on the inclined groove 101. As the ball 102 is further pushed in, the ball 102 will contact the guiding tube 204 inside the guiding groove 2. At this time, the telescopic rod 202 and the spring 203 at the bottom of the guiding tube 204 will be compressed inward under the action of the ball 102, driving the guiding tube 204 inward, so that the ball 102 smoothly enters the internal limiting groove 205 along the guiding tube 204. After the ball 102 completely enters the limiting groove 205, the elastic force of the spring 203 and the telescopic rod 202 will cause the guiding tube 204 to return to its initial position. At this time, the guiding tube 204 rebounds outward, and the top of the guiding tube 204 restricts the ball 102 in the limiting groove 205 to prevent the ball 102 from sliding out along the guiding groove 2. Then, the cage 3 is placed on the outer surface of the ball 102, and the cage 3 is tightly clamped with the ball 102 through the clamping ring 301. At the same time, it is ensured that the vibration isolation layer 303 on the inner surface of the connecting block 302 is closely attached to the outer surface of the ball 102. By using the vibration isolation layer 303 made of silicone material, the impact force and vibration amplitude during the operation of the bearing are reduced to improve the vibration isolation effect. Subsequently, the inner bearing ring 305 is placed on one side inside the ball 102 to ensure that the ball 102 can rotate freely between the inner bearing ring 305 and the outer bearing ring 1. Finally, a set of cages 3 are fixed together with the fixing bolt 304 to complete the installation of the bearing.

[0024] As Figures 1-4As shown, the inclined groove 101 is formed between the limiting groove 205 and the outer ring 1 of the bearing. One side outer wall of the ball 102 is rotatably connected to the inner surface of the outer ring 1 of the bearing through the limiting groove 205. The guiding grooves 2 are annularly distributed on the outer surface of the inclined groove 101. The spring 203 is coated outside the telescopic rod 202. Both the telescopic rod 202 and the spring 203 are fixed between the guiding tube 204 and the fixed seat 201. The other side bottom end of the guiding tube 204 is rotatably connected to the bottom inner wall of the guiding groove 2. The guiding tube 204 and the inner side of the guiding groove 2 form a telescopic structure through the cooperation of the telescopic rod 202 and the spring 203.

[0025] By pushing the ball 102 into the interior of the outer ring 1 of the bearing along the direction of the inclined groove 101, during the process of the ball 102 entering the inclined groove 101, it will slide along the guiding groove 2 on the inclined groove 101. As the ball 102 is further pushed in, the ball 102 will contact the guiding tube 204 in the guiding groove 2. At this time, the telescopic rod 202 and the spring 203 at the bottom of the guiding tube 204 will be compressed inward under the action of the ball 102, driving the guiding tube 204 inward, so that the ball 102 smoothly enters the inner limiting groove 205 along the guiding tube 204. After the ball 102 completely enters the limiting groove 205, the elastic force of the spring 203 and the telescopic rod 202 will make the guiding tube 204 return to the initial position. At this time, the guiding tube 204 rebounds outward, and the top of the guiding tube 204 restricts the ball 102 in the limiting groove 205, preventing the ball 102 from sliding out along the guiding groove 2. The guiding groove 2 and the guiding tube 204 make the installation process of the ball 102 simple and fast, and at the same time ensure the accuracy of the position of the ball 102. At the same time, since the ball 102 is restricted by the guiding tube 204 and the limiting groove 205, its position is relatively stable and not easy to fall off, thus ensuring the stability of the bearing during use.

[0026] As Figures 1-4 shown, the cage 3 is snap - connected to the ball 102 through the snap - ring 301. A number of connecting blocks 302 are provided. The vibration isolation layer 303 is made of silica gel material. The inner surface of the vibration isolation layer 303 is closely attached to the outer surface of the ball 102. The other side outer wall of the ball 102 is rotatably connected to the surface of the inner ring 305 of the bearing. The ball 102 is rotatably connected between the inner ring 305 of the bearing and the outer ring 1 of the bearing. The cage 3 is provided as a set. The cages 3 are symmetrically distributed at the upper and lower ends of the ball 102. A set of cages 3 are fixedly connected by fixing bolts 304.

[0027] After the ball 102 is placed at the center inside the outer bearing ring 1, ensure that the ball 102 can rotate freely. Then place the cage 3 on the outer surface of the ball 102, and tightly engage the cage 3 with the ball 102 through the clamping ring 301. At the same time, ensure that the vibration isolation layer 303 on the inner surface of the connecting block 302 is in close contact with the outer surface of the ball 102. By using the vibration isolation layer 303 made of silicone material, reduce the impact force and vibration amplitude during the operation of the bearing to improve the vibration isolation effect. Subsequently, place the inner bearing ring 305 on one side inside the ball 102, ensure that the ball 102 can rotate freely between the inner bearing ring 305 and the outer bearing ring 1. Finally, use the fixing bolt 304 to fix a group of cages 3 together to complete the installation of the bearing.

[0028] Working principle: During installation, the ball 102 is pushed into the inside of the outer bearing ring 1 along the direction of the inclined groove 101. During the process of the ball 102 entering the inclined groove 101, it will slide along the guide groove 2 on the inclined groove 101. As the ball 102 is further pushed in, the ball 102 will contact the guide tube 204 in the guide groove 2. At this time, the telescopic rod 202 and the spring 203 at the bottom of the guide tube 204 will be compressed inward under the action of the ball 102, driving the guide tube 204 inward, so that the ball 102 smoothly enters the internal limit groove 205 along the guide tube 204. After the ball 102 completely enters the limit groove 205, the elastic force of the spring 203 and the telescopic rod 202 will cause the guide tube 204 to return to its initial position. At this time, the guide tube 204 rebounds outward, and the top of the guide tube 204 restricts the ball 102 in the limit groove 205 to prevent the ball 102 from sliding out along the guide groove 2. The guide groove 2 and the guide tube 204 make the installation process of the ball 102 simple and fast, and at the same time ensure the accuracy of the position of the ball 102. At the same time, since the ball 102 is restricted by the guide tube 204 and the limit groove 205, its position is relatively stable and not easy to fall off, thus ensuring the stability of the bearing during use.

[0029] After the ball 102 is placed at the center inside the outer bearing ring 1, ensure that the ball 102 can rotate freely. Then place the cage 3 on the outer surface of the ball 102, and tightly engage the cage 3 with the ball 102 through the clamping ring 301. At the same time, ensure that the vibration isolation layer 303 on the inner surface of the connecting block 302 is in close contact with the outer surface of the ball 102. By using the vibration isolation layer 303 made of silicone material, reduce the impact force and vibration amplitude during the operation of the bearing to improve the vibration isolation effect. Subsequently, place the inner bearing ring 305 on one side inside the ball 102, ensure that the ball 102 can rotate freely between the inner bearing ring 305 and the outer bearing ring 1. Finally, use the fixing bolt 304 to fix a group of cages 3 together to complete the installation of the bearing.
