Description

Technical Field

[0001] The invention relates to the technical field of fully split bearing design, in particular to a reinforced fully split electrical corrosion resistant rolling bearing and a mounting method thereof. Background Art

[0002] In application scenarios where it is very difficult to replace bearings, the use of fully split rolling bearings is a very important option. Most of the installation and disassembly steps can be omitted, such as disassembly of gears, clutches and transmission units, which can significantly reduce the cost of bearing installation and disassembly.

[0003] Electrical corrosion failure is a common failure mode of bearings. Bearing failure caused by electrical corrosion seriously affects the reliability of the entire machine, such as in the offshore wind power field.

[0004] At present, fully split rolling bearings are mostly cut by wire cutting to split the outer ring, inner ring, cage roller assembly and other parts into two halves with a small V-shaped angle, and then clamped together by bolts during installation. In addition, insufficient attention has been paid to preventing electrical corrosion.

[0005] The defects of existing fully split rolling bearings are as follows: ① An interference fit is usually adopted between the inner diameter of the rolling bearing and the main shaft. After the bearing is installed on the main shaft, no matter whether the inner ring of the bearing is provided with a clamping ring or not, it is only clamped by bolts, and the inner ring of the bearing is prone to micro-expansion due to the force; ② The rolling bearing transmits the load through the inner diameter of the bearing during operation, and the micro-expansion of the inner ring of the bearing will be further aggravated, and the fastening bolts of the inner ring may also cause fatigue fracture due to long-term tensile force; ③ There is a certain sharp edge effect in the gap between the outer ring and the inner ring wire cutting joint surface; ④ There is no targeted design for the common electrical corrosion phenomenon of bearings.

[0006] The existence of the above-mentioned defects leads to a significant reduction in the performance of the fully split bearing, which in turn limits the application scenarios of the fully split rolling bearing. Summary of the invention

[0007] The purpose of the present invention is to provide a reinforced fully-split electrical corrosion-resistant rolling bearing and an installation method thereof, which can solve the technical problem that the existing fully-split bearings have low performance and limited application scenarios.

[0008] In order to achieve the above object, the present invention adopts the following technical solution.

[0009] A reinforced fully split electrical corrosion resistant rolling bearing comprises a splittable bearing inner ring, a bearing outer ring and a retaining frame roller assembly. The bearing inner ring comprises a split inner ring one and a split inner ring two. The split inner ring one and the split inner ring two are fixed into a ring by a clamping ring.

[0010] Split inner ring one and split inner ring two are provided with snap-fit ​​structures for circumferentially fixing split inner ring one and split inner ring two at two connection points. The snap-fit ​​structure includes a protruding wedge structure provided on split inner ring one and a groove structure provided on split inner ring two and cooperating with the wedge structure. The relative sliding of split inner ring one and split inner ring two along the axial direction of the bearing can realize the clamping and separation of the snap-fit ​​structure.

[0011] The cage roller assembly comprises rollers, and the surfaces of the rollers are provided with an insulating coating for slowing down the electrochemical corrosion of the bearings.

[0012] Furthermore, the split inner ring 1 is provided with wedge structures at both axial ends of the connection surface with the split inner ring 2, and the split inner ring 2 is provided with groove structures for cooperating with the wedge structures at positions corresponding to the wedge structures.

[0013] Furthermore, a clamping ring is provided at each of the two axial ends of the inner ring of the bearing, and an inner diameter of the clamping ring and an outer diameter of the inner ring of the bearing are in interference fit.

[0014] Furthermore, the outer ring of the bearing includes a split outer ring 1 and a split outer ring 2, the connecting surface of the split outer ring 1 and the split outer ring 2 is a V-shaped surface, the split outer ring 1 and the split outer ring 2 are both provided with outer ring locating pins at the connection, and the split outer ring 1 and the split outer ring 2 are fixedly connected by outer ring fixing screws.

[0015] Furthermore, the roller (31) uses DLC surface coating technology to produce a coating with an insulating effect on its surface.

[0016] Furthermore, the cage roller assembly also includes two split cage assemblies, the roller is rotatably arranged on the split cage assemblies, the two split cage assemblies are both provided with cage locating pins at the connecting surface, and the two split cage assemblies are fixedly connected by cage fixing screws and cage connecting plates.

[0017] Furthermore, the clamping ring comprises a split clamping ring 1 and a split clamping ring 2, and the split clamping ring 1 and the split clamping ring 2 are fixedly connected by a clamping ring set screw.

[0018] Furthermore, the plane where the connection surface of the split clamping ring 1 and the split clamping ring 2 is located and the plane where the connection surface of the split inner ring 1 and the split inner ring 2 is located are perpendicular to each other.

[0019] Furthermore, the split inner ring 1 and the split inner ring 2 are manufactured by dividing the same complete bearing inner ring using wire cutting.

[0020] A method for installing a reinforced fully-split electrical corrosion-resistant rolling bearing comprises the following steps.

[0021] Step 1: Install the split inner ring 1 at the corresponding position of the main shaft, and apply grease on the connecting surfaces of the split inner ring 1 and the split inner ring 2. The split inner ring 2 is axially offset from the split inner ring 1 to fit the connecting surfaces, and the split inner ring 2 is axially slid to make the groove structure match the wedge structure.

[0022] Step 2: Install clamping rings at both axial ends of the bearing inner ring. During installation, the plane where the connecting surfaces of split clamping ring 1 and split clamping ring 2 are located is perpendicular to the plane where the connecting surfaces of split inner ring 1 and split inner ring 2 are located. Split inner ring 1, split inner ring 2 and clamping ring together constitute the bearing inner ring.

[0023] Step three, assemble and install the two split cage assemblies at corresponding positions of the inner ring of the bearing using cage locating pins and cage fixing screws.

[0024] Step 4: Apply grease to the connection surfaces of split outer ring 1 and split outer ring 2, and use the outer ring locating pin and outer ring set screw to assemble and install them in the corresponding position of the cage roller assembly. Split outer ring 1 and split outer ring 2 together constitute the bearing outer ring.

[0025] Step 5: Install the outer ring of the bearing into the bearing seat and the installation is completed.

[0026] Furthermore, in step one, the split inner ring one and the split inner ring two need to be heated before installation.

[0027] Furthermore, in step five, the outer ring of the bearing is installed at the corresponding position of the bearing base, and after heating the contact part between the bearing seat upper cover and the bearing outer ring, the bearing seat upper cover is hoisted to cooperate with the bearing base, and the bearing seat upper cover is fixed to the bearing base through the bearing seat locating pin and the bearing seat locking screw.

[0028] After adopting the above technical solution, the present invention has the following beneficial effects: 1. In the present invention, a buckle structure for circumferentially fixing the inner ring of the bearing is provided at the junction of the first split inner ring and the second split inner ring, and a clamping ring is used to achieve all-round locking, and the locking effect is more accurate and firm, which inhibits the micro-expansion of the inner ring of the bearing when it is loaded, and avoids the set screw used to fix the inner ring of the bearing from being subjected to excessive tension and causing metal fatigue; 2. In the present invention, the plane where the connection surface of the split clamping ring 1 and the split clamping ring 2 is located is perpendicular to the plane where the connection surface of the split inner ring 1 and the split inner ring 2 is located, which can optimize the force of the inner ring of the bearing and improve the overall stability; 3. In the present invention, the connection surface of the split outer ring 1 and the split outer ring 2 is a V-shaped surface, and an outer ring positioning pin is provided at the same time, so that the positioning is more accurate by the dual positioning method of the V-shaped surface and the outer ring positioning pin; 4. During installation, the present invention can improve the sharp edge effect existing on the joint surface by applying a small amount of lubricating grease on the joint surfaces of the inner ring and the outer ring of the bearing; 5. The rollers in the present invention are treated with DLC surface coating technology, which makes the bearing have a certain insulation effect and can significantly improve the electrical corrosion resistance of the bearing.

[0046] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the following is a further detailed description of the characteristics and performance of a reinforced fully split electrical corrosion resistant rolling bearing and its installation method in the present invention in conjunction with the accompanying drawings and embodiments.

[0047] Embodiment 1 Please see attached Figures 1 to 8 A reinforced fully split electric corrosion resistant rolling bearing comprises a split bearing inner ring 1, a bearing outer ring 2, and a cage roller assembly 3. The bearing inner ring 1 comprises a split inner ring 11 and a split inner ring 2 12. The split inner ring 11 and the split inner ring 2 12 are fixed into a ring by a clamping ring 13. The clamping ring 13 is provided at each of the axial ends of the bearing inner ring 1, and the inner diameter of the clamping ring 13 is interference fit with the outer diameter of the bearing inner ring 1.

[0048] The clamping ring 13 includes a split clamping ring 1 131 and a split clamping ring 2 132, and the split inner ring 1 11 and the split inner ring 2 12 are made by wire cutting from the same complete bearing inner ring 1. The split clamping ring 1 131 and the split clamping ring 2 132 are fixedly connected by a clamping ring set screw 133.

[0049] The split inner ring one 11 and the split inner ring two 12 are provided with a snap structure 14 for circumferentially fixing the split inner ring one 11 and the split inner ring two 12 at two connection points. The snap structure 14 includes a protruding wedge structure 141 provided on the split inner ring one 11 and a groove structure 142 provided on the split inner ring two 12 and cooperating with the wedge structure 141. The relative sliding of the split inner ring one 11 and the split inner ring two 12 along the axial direction of the bearing can realize the clamping and separation of the snap structure 14.

[0050] In the specific setting, the split inner ring 11 is provided with wedge structures 141 at both axial ends of the connection surface with the split inner ring 2 12, and the split inner ring 2 12 is provided with a groove structure 142 for cooperating with the wedge structure 141 at a position corresponding to the wedge structure 141.

[0051] In particular, when the clamping ring 13 is used to fix the bearing inner ring 1, the plane where the connecting surface of the split clamping ring 1 131 and the split clamping ring 2 132 is located is perpendicular to the plane where the connecting surface of the split inner ring 1 11 and the split inner ring 2 12 is located.

[0052] The bearing outer ring 2 includes a split outer ring 1 21 and a split outer ring 22. The connecting surface between the split outer ring 1 21 and the split outer ring 22 is a V-shaped surface. The split outer ring 1 21 and the split outer ring 22 are both provided with outer ring locating pins 23 at the connection. The split outer ring 1 21 and the split outer ring 22 are fixedly connected by outer ring fixing screws 24.

[0053] The cage roller assembly 3 includes a roller 31. The surface of the roller 31 is provided with an insulating coating for alleviating electrochemical corrosion of the bearing. The roller 31 uses DLC surface coating technology to produce a coating with an insulating effect on its surface.

[0054] The cage roller assembly 3 also includes two split cage assemblies 32, the roller 31 is rotatably arranged on the split cage assemblies 32, and the two split cage assemblies 32 are both provided with cage locating pins 33 at the connecting surface. The two split cage assemblies 32 are fixedly connected by cage fixing screws 34 and cage connecting plates 35.

[0055] In specific implementation, a reinforced fully split electric corrosion resistant rolling bearing and its supporting structure are composed of a reinforced fully split rolling bearing, a main shaft 4, a bearing base 51, a bearing seat upper cover 52, a bearing seat locating pin 53, and a bearing seat set screw 54. The bearing seat 5 is composed of a bearing base 51 and a bearing seat upper cover 52, which are positioned by the bearing seat locating pin 53 and fastened by the bearing seat set screw 54, and are combined into a bearing seat 5 as a whole for supporting the bearing outer ring 2.

[0056] The basic structure of the reinforced fully split rolling bearing consists of a bearing inner ring 1, a bearing outer ring 2, and a cage roller assembly 3.

[0057] The basic structure of the bearing outer ring 2 is composed of a split outer ring 1 21, a split outer ring 22, an outer ring positioning pin 23, and an outer ring set screw 24. The bearing outer ring 2 adopts a double positioning method of outer ring positioning pin 23 and cutting a small V-shaped surface to achieve more accurate positioning, and adopts a fastening method of two rows of outer ring set screws 24 to achieve more reliable fastening.

[0058] The basic structure of the bearing inner ring 1 is composed of a split inner ring 11 and a split inner ring 2 12. The basic structure of the clamping ring 13 is composed of a split clamping ring 1 131, a split clamping ring 2 132, and a clamping ring set screw 133. The clamping ring 13 is interference fit with the outer diameter surface of the edge of the bearing inner ring 1, and the angle between the joint surfaces of the two halves of the clamping ring 13 and the joint surfaces of the two halves of the bearing inner ring 1 is required to be about 90° for installation. At this time, the force is optimally decomposed and the clamping is more secure. Specifically, in actual operation, in order to reduce the difficulty of assembly, the angle is not strictly limited to 90°, and it can be around 90°. As a preference, the angle is between 60° and 120°.

[0059] The inner ring 1 of the bearing innovatively adopts a zigzag cutting method to cut the inner ring into two half rings and form a certain snap-fit ​​structure 14. During installation, it is inserted and spliced, and then clamped with a clamping ring 13 with a certain interference fit to achieve radial full-dimensional locking. The locking effect is more precise and firm, and the radial micro-expansion phenomenon of the inner ring 1 of the bearing when loaded is avoided.

[0060] The basic structure of the bearing outer ring 2 is composed of a split outer ring 1 21 , a split outer ring 22 , an outer ring locating pin 23 , and an outer ring set screw 24 .

[0061] The cage roller assembly 3 is composed of two split cage assemblies 32 and rollers 31 .

[0062] The bearing inner ring 1 and the cage roller assembly 3 are installed on the main shaft 4, and the bearing outer ring 2 is installed in the bearing seat 5 for supporting the shaft system.

[0063] Embodiment 2 Please see attached Figures 9 to 16 , a method for installing a reinforced fully split electrical corrosion resistant rolling bearing comprises the following steps.

[0064] Step one, install the split inner ring 11 at the corresponding position of the main shaft 4, and apply grease on the connecting surfaces of the split inner ring 11 and the split inner ring 2 12. The split inner ring 2 12 is axially offset from the split inner ring 11 to fit the connecting surfaces, and the split inner ring 2 12 is axially slid to make the groove structure 142 cooperate with the wedge structure 141.

[0065] In particular, the split inner ring 1 1 and the split inner ring 2 12 both need to be heated before installation.

[0066] Step 2: Install the clamping ring 13 at both axial ends of the bearing inner ring 1. During installation, the plane where the connecting surface of the split clamping ring 1 131 and the split clamping ring 2 132 is located is perpendicular to the plane where the connecting surface of the split inner ring 1 11 and the split inner ring 2 12 is located. The split inner ring 1 11, the split inner ring 2 12 and the clamping ring 13 together constitute the bearing inner ring 1.

[0067] Step three: The two split cage assemblies 32 are assembled and installed at corresponding positions of the bearing inner ring 1 using the cage positioning pins 33 and the cage fixing screws 34 .

[0068] Step 4: Apply grease on the connecting surfaces of split outer ring 1 21 and split outer ring 2 22, and use outer ring locating pin 23 and outer ring fixing screw 24 to assemble and install them at the corresponding position of cage roller assembly 3. Split outer ring 1 21 and split outer ring 2 22 together constitute the bearing outer ring 2.

[0069] Step five, install the bearing outer ring 2 into the bearing seat 5, and the installation is completed.

[0070] Specifically, the bearing outer ring 2 is installed at the corresponding position of the bearing base 51. After heating the contact portion between the bearing seat upper cover 52 and the bearing outer ring 2, the bearing seat upper cover 52 is hoisted to cooperate with the bearing base 51, and the bearing seat upper cover 52 is fixedly connected to the bearing base 51 by the bearing seat locating pin 53 and the bearing seat fixing screw 54.

[0071] In the specific implementation, firstly, the main shaft 4 is placed vertically with the large end face downwards and leveled. Then, the inner diameter surface of the split inner ring 11 is heated, and after heating, it is installed in the corresponding position of the main shaft 4 and a small amount of grease is applied to the online cutting joint surface.

[0072] Then, the inner diameter surface of the split inner ring 2 12 is heated. After the heating is completed, a small amount of grease is first applied to the online cutting joint surface, and then it is moved axially with the split inner ring 1 11 at a certain offset until it is combined with the split inner ring 1 11 as a whole.

[0073] The split inner ring 11 and the split inner ring 2 12 are locked at the corresponding positions on the main shaft 4 by the clamping ring 13. The two halves of the clamping ring 13 and the two halves of the bearing inner ring 1 are required to be installed at about 90 degrees. At this time, the force is optimally decomposed and the clamping is more secure. Finally, the clamping device is used to clamp the inner ring.

[0074] The two split cage assemblies 32 are positioned by the cage positioning pins 33 , fastened together as a whole by the cage fixing screws 34 and the cage connecting plates 35 , and installed at the corresponding positions of the bearing inner ring 1 .

[0075] A small amount of grease is applied to the joint surface of the split outer ring 1 21 and the split outer ring 2 22, and the outer ring positioning pin 23 is used to position the outer ring, and the outer ring set screw 24 is used to tighten the assembly as a whole and install it in the corresponding position of the cage roller assembly 3. The bearing seat 5 can limit the radial direction of the bearing outer ring 2, so the traditional two-half cutting method with a small V-shaped angle can be used.

[0076] The bearing seat 5 is assembled with the main shaft 4. The outer ring mounting surface of the bearing seat upper cover 52 is heated, and the bearing seat upper cover 52 is hoisted to be combined with the bearing base 51. The two are positioned by the bearing seat locating pin 53 and fastened by the bearing seat set screw 54 to form a whole, and then the bearing outer ring 2 is pressed by the pressing device.

[0077] After cooling to room temperature, the installation is completed.

[0078] It should be noted that the parts not described in detail in this scheme are all prior art, and the above embodiments are only used to illustrate the present invention, but the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the protection scope of the present invention.
