Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to an anti-creep deep groove ball bearing. Background Art

[0002] Deep groove ball bearings are characterized by low friction resistance and high speed. They can be used on parts that bear radial loads or combined loads of radial and axial loads. They can also be used on parts that bear axial loads. They are commonly used in small power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

[0003] However, during actual use, the applicant discovered the following technical problems:

[0004] 1. Creep between the outer ring and the bearing seat is mainly caused by factors such as bearing technical parameters, matching conditions or load conditions. Creep not only causes wear on the matching surfaces of the bearing and the bearing seat, but may also cause shaft deflection or tilt, thereby generating abnormal noise and vibration.

[0005] 2. When faced with deep groove ball bearing application scenarios with diverse width and specification requirements, deep groove ball bearings that rely on fixed sizes are very likely to be unable to adapt to the size, resulting in the need to re-customize deep groove ball bearings of corresponding specifications, which is time-consuming and wasteful.

[0006] To this end, the present application provides an anti-creep deep groove ball bearing to meet the needs. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide an anti-creep deep groove ball bearing.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0010] The outer ring and inner ring and the balls placed between them;

[0011] Width extension components, which are arranged on the sides of the outer ring and the inner ring;

[0012] The width extension assembly consists of a first width extension ring and a second width extension ring located on the sides of the outer ring and the inner ring, wherein the first width extension ring passes through the outer ring and the inner ring and is connected to the second width extension ring;

[0013] The outer ring, the first extension ring and the second extension ring are all provided with anti-creeping cuts.

[0014] Optionally, a connecting block is fixed on one side of the first widening ring, a connecting groove is provided on one side of the second widening ring, and fixing grooves are provided through the outer ring and the inner ring. The connecting block passes through the fixing groove and is connected to the connecting groove, thereby fixing the first widening ring and the second widening ring on the sides of the outer ring and the inner ring.

[0015] Optionally, a first through hole is provided in the connecting groove, and a first fixing bolt is configured with a thread inside the first through hole. The first fixing bolt passes through the first through hole to achieve a threaded connection with the connecting block. The connecting block is firmly fixed in the connecting groove by the first bolt and the characteristics of the thread to prevent the first widening ring or the second widening ring from falling off during use.

[0016] Optionally, the outer ring is composed of a semicircular part A and a part B, one side of the part A is symmetrically provided with a positioning block, and one side of the part B is symmetrically provided with a positioning groove, and the positioning block is placed in the positioning groove. The two positioning blocks are respectively inserted into the positioning grooves to achieve fixation between part A and part B.

[0017] Optionally, teeth are provided between the symmetrically arranged positioning blocks, and tooth grooves are provided between the symmetrically opened positioning grooves, and the teeth are matched with the tooth grooves. By providing teeth and tooth grooves on parts A and B, the bite strength between the two is increased, thereby preventing the positioning blocks from breaking under high-intensity load work.

[0018] Optionally, a second through hole is provided in the positioning groove, and a second fixing bolt is arranged in the second through hole. The second fixing bolt passes through the second through hole and is threadedly connected to the positioning block. The positioning block is firmly fixed in the positioning groove by the second bolt and the characteristics of the thread to prevent parts A and B from falling off during use.

[0019] Optionally, the outer sides of the first fixing bolt and the second fixing bolt are both threaded structures, and a hexagonal hole is opened on the top. The opening of the hexagonal hole allows them to be installed and disassembled using a hexagonal wrench. Using a hexagonal wrench can rotate the first fixing bolt and the second fixing bolt faster, transmit greater torque, and thus speed up the installation and disassembly.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] By adding extension components to the sides of the outer and inner rings, the bearing can be widened, effectively avoiding the situation where deep groove ball bearings cannot be adapted due to dimensional requirements. By simply adding extension components, the deep groove ball bearing can be widened, effectively saving time and cost. At the same time, the outer diameter of the outer ring is designed with an arc-shaped cutout across the entire width to avoid contact with the bearing seat, effectively blocking the traveling waves caused by the rolling element load under the load zone of the outer ring, thereby preventing the occurrence of creep.

[0042] like Figure 1-Figure 3 and Figure 6 As shown, an embodiment of the present invention provides an anti-creep deep groove ball bearing, comprising an outer ring 1 and an inner ring 2, with a plurality of balls 3 sandwiched between the outer ring 1 and the inner ring 2. A widening assembly 4 for widening the bearing is installed on the sides of the outer ring 1 and the inner ring 2. The widening assembly 4 includes a first widening ring 41 and a second widening ring 42. The first widening ring 41 is located on one side of the outer ring 1 and the inner ring 2, and the second widening ring 42 is located on the other side of the outer ring 1 and the inner ring 2. The first widening ring 41 passes through the outer ring 1 and the inner ring 2 and is clamped to the second widening ring 42.

[0043] The outer ring 1, the first extension ring 41 and the second extension ring 42 are all provided with arc-shaped cutouts 5. The setting of the cutouts 5 effectively prevents the bearing from creeping under specific load conditions while maintaining the ease of assembly and durability of the bearing.

[0044] By adding extension components 4 to the sides of the outer ring 1 and inner ring 2, the bearing can be widened, effectively avoiding the problem of deep groove ball bearings being unable to adapt due to dimensional requirements. This installation saves time and money. Furthermore, an arc-shaped cutout 5 is designed along the full width of the outer diameter of the outer ring 1 to prevent contact with the bearing seat. This effectively blocks the traveling waves caused by the rolling element load below the outer ring's load zone, thus preventing creep.

[0045] The specific installation method of the extension component 4 is as follows: Figure 3 and Figure 6 As shown, several connecting blocks 43 are fixed on the side of the first widening ring 41. The connecting blocks 43 can be fixed to the side of the first widening ring 41 by welding or in an integral manner. The integral setting is made by lathe processing. Several connecting grooves 44 are opened on the side of the second widening ring 42, and several fixing grooves 6 are opened on the outer ring 1 and the inner ring 2. Several connecting blocks 43 on the side of the first widening ring 41 pass through the several fixing grooves 6 on the outer ring 1 and the inner ring 2 and are inserted into the several connecting grooves 44, thereby fixing the first widening ring 41 and the second widening ring 42 to the sides of the outer ring 1 and the inner ring 2.

[0046] In order to reinforce the first widening ring 41 and the second widening ring 42 to prevent the deep groove ball bearing from falling off during use, the following steps are used: Figure 3 and Figure 6 As shown, a first through hole is opened in the connecting groove 44, the first through hole is a threaded hole, and the first fixing bolt is threadedly connected to the first through hole. The first fixing bolt passes through the first through hole from above the second widening ring 42 and is threadedly connected to the connecting block 43. The first bolt should be inside the first through hole, and care should be taken to avoid being parallel to or extending with the second widening ring 42 above it to prevent wear of the bearing seat. The connecting block 43 is firmly fixed in the connecting groove 44 by the first bolt and the characteristics of the thread to prevent the first widening ring 41 or the second widening ring 42 from falling off during use.

[0047] When the balls 3 between the outer ring 1 and the inner ring 2 are easily stuck after long-term use, which may cause the bearing to be damaged and replaced. Figure 1-5 To avoid this, specifically: the outer ring 1 is divided into two semicircular parts A11 and part B12, and parts A11 and B12 are directly spliced together so that when the ball 3 gets stuck, the two can be disassembled, so that the ball 3 and its outer ring 1 and inner ring 2 can be cleaned, so as to reuse and reduce losses. Two positioning blocks 111 are fixed on one side of part A11, and two positioning grooves 121 are opened on one side of part B12. The two positioning blocks 111 are respectively inserted into the positioning grooves 121 to achieve fixation between part A11 and part B12.

[0048] When the positioning block 111 is used for a long time, it may break due to high-intensity load, thereby causing the fixed connection between component A11 and component B12 to be damaged and unusable. Figure 3-5 To avoid this problem: a tooth 112 is provided between the two positioning blocks 111 on component A11, and the positioning block 111 and the tooth 112 on component A11 are both processed by a lathe; a tooth groove 122 is provided between the two positioning grooves 121 on component B12, and the positioning grooves 121 and the tooth grooves 122 on component B12 are both processed by a lathe, and the tooth 112 is matched with the tooth groove 122. By providing the teeth 112 and the tooth grooves 122 on components A11 and B12, the bite strength between the two is increased, thereby avoiding the positioning block 111 from breaking under high-intensity load operation.

[0049] In order to strengthen the fixing effect of the positioning block 111 inside the positioning groove 121 and prevent parts A11 and B12 from falling off during use, a second through hole is opened in the positioning groove 121 as shown in 4-5, and a second fixing bolt is threadedly connected to the second through hole. The second fixing bolt passes through the second through hole from above part B12 and is threadedly connected to the positioning block 111. The second bolt should be inside the second through hole, and care should be taken to avoid being parallel to or extending above part B12 to prevent wear of the bearing seat. The positioning block 111 is firmly fixed in the positioning groove 121 by the second bolt and the characteristics of the thread to prevent parts A11 and B12 from falling off during use.

[0050] Furthermore, Figure 7 As shown, the first fixing bolt and the second fixing bolt have the same structure, and the outer walls are threaded structures. A hexagonal hole is provided on the top to increase the fixing effect through the thread. At the same time, the hexagonal hole allows for installation and removal using a hexagonal wrench. Using a hexagonal wrench can rotate the first fixing bolt and the second fixing bolt faster, transmit greater torque, and thus speed up installation and removal.

[0051] The working principle of the utility model

[0052] When the bearing needs to be widened during use, a fixing groove 6 is opened on the standard bearing part of the lathe, and the first extension ring 41 and the second extension ring 42 of the corresponding size are taken. The connecting block 43 on the side of the first extension ring 41 is passed through the fixing groove 6 in the outer ring 1 and the inner ring 2, and then inserted into the connecting groove 44 on the side of the second extension ring 42, and fixed with the first fixing bolt to achieve the widening purpose.

[0053] When the ball 3 between the outer ring 1 and the inner ring 2 becomes stuck, use a hexagonal wrench to remove the second fixing bolt in the second through hole, then separate parts A11 and B12 to clean parts A11, B12 and ball 3. After cleaning, install ball 3 between parts A11 and B12. At this time, the positioning block 111 is aligned with the positioning groove 121 and inserted, and is fixed in the second through hole by threading with the second fixing bolt. When the positioning block 111 is fully inserted into the positioning groove 121, the teeth 112 match the tooth groove 122 to increase the bite force.

[0054] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
