Description

Technical Field

[0001] The invention relates to the technical field of bearing installation, and in particular to a bearing limiting and anti-loosening device. Background Art

[0002] At present, the existing spindle bearing anti-skid limiter adopts a single screw to support the left and right sides of the bearing base, and the bearing is set on the bearing base to limit the bearing. Since the two sides of the standard bearing base are arc surfaces, the bearing base is subjected to large forces when the equipment is running. When a single screw pushes the bearing base, the contact area is small, and the strength of a single screw is low, resulting in poor limiting effect. After the equipment has been running for a period of time, the bearing base is prone to loosening and sliding, seriously affecting the service life of the equipment. In addition, due to the small contact area between the screw and the bearing base, the contact pressure is large, which can easily cause damage to the bearing base. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a bearing limiting and anti-loosening device with a simple structure to expand the contact area with the bearing base, avoid the bearing base from being damaged, and limit the bearing stably and reliably.

[0004] In order to solve the above technical problems, the purpose of the present invention is achieved through the following technical solutions: providing a bearing limit and anti-loosening device, comprising two relatively arranged limit and anti-loosening modules, the limit and anti-loosening module comprising a base, two top screws and a limit block, the base comprising a main board; the two top screws are arranged in parallel and are both vertically penetrated on the main board, one end of the top screw passes through the main board and a top screw nut is threadedly provided; the limit block is connected to one end of the top screw, and the side of the limit block away from the top screw forms an arc surface for fitting with the side of the bearing base, and the limit block is fixed by a fastener.

[0005] A further technical solution is as follows: the base further comprises a support plate, and the support plate is vertically arranged on a side of the main board away from the limiting block.

[0006] A further technical solution is: the support plate is located at the upper end of the main board.

[0007] A further technical solution is that the support plate and the main plate are formed integrally.

[0008] Its further technical solution is: the limit block includes a base plate and a limit plate vertically arranged on the base plate, one end of the top screw is connected to the limit plate, the arc surface is formed on the side of the limit plate away from the top screw to fit with the side of the bearing base, and the base plate is provided with a fixing groove for setting the fastener.

[0009] A further technical solution is as follows: a support member is connected between the limit plate and the bottom plate to support the limit plate and the bottom plate.

[0010] A further technical solution thereof is that the support member is a support plate in the shape of a right triangle, and the two right-angled sides of the support plate are respectively connected to the limiting plate and the bottom plate.

[0011] A further technical solution thereof is that the number of the support members is two and they are respectively arranged on the front and rear sides of the bottom plate.

[0012] The beneficial technical effects of the present invention are as follows: An anti-loosening device for bearing limit in the present invention has two oppositely arranged anti-loosening modules for limit. One end of the setscrew of the anti-loosening module for limit is connected to the limiting block. By forming an arc surface on the side of the limiting block away from the setscrew to fit the side surface of the bearing base, the limiting block can be closely attached to the bearing base to prevent loosening, effectively expanding the contact area between the arc surface of the limiting block and the side surface of the bearing base, reducing the contact pressure of the bearing base, thereby ensuring the normal use of the bearing base. At the same time, the double setscrews are used to tighten the limiting block, effectively ensuring the force-bearing strength of the limiting block against the sliding of the bearing base, preventing the displacement of the bearing base caused by excessive force during rotation, making the limit of the bearing stable and reliable, and avoiding damage to the bearing base. The structure is compact, simple and reliable, and the work is stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Please refer to Figures 1 to 4 as shown in Figure 1 a structural schematic diagram of a bearing limit and anti-loosening device provided by an embodiment of the present invention. The bearing limit and anti-loosening device includes two relatively arranged limit and anti-loosening modules 1. The limit and anti-loosening module 1 includes a base 11, two set screws 12 and a limit block 14. The base 11 includes a main board 111. The two set screws 12 are arranged in parallel and vertically penetrate through the main board 111. One end of the set screw 12 passes through the main board 111 and is threadedly sleeved with a set screw nut 13. The limit block 14 is connected to one end of the set screw 12. An arc surface 141 for fitting with the side surface of the bearing base 2 is formed on the side of the limit block 14 away from the set screw 12. The limit block 14 is fixed by a fastener 15.

[0024] Among them, the bearing 3 is installed on the bearing base 2. The bearing base 2 can be fixed on the main structure 4 by bolts 21 cooperating with connecting nuts to prevent the bearing base 2 from shifting in the vertical direction. By limiting and fixing the bearing base 2, the bearing 3 can be limited and fixed. The process of installing the bearing 3 and the bearing limiting and anti-loosening device on the main structure 4 is as follows: Install the base 11 on the main structure 4 corresponding to the position of the main structure 4 to initially pre-fix the position of the limiting and anti-loosening module 1. The other end of the set screw 12 passes through the main board 111 of the corresponding base 11, and a set screw nut 13 is threadedly sleeved on one end of the set screw 12. The ends of the set screws 12 of the two limiting and anti-loosening modules 1 face each other. Place the bearing base 2 with the bearing 3 installed between the bases 11 of the two limiting and anti-loosening modules 1 so that the bearing base 2 is located between the ends of the set screws 12 of the two limiting and anti-loosening modules 1. Fix the bearing base 2 by bolts 21 cooperating with connecting nuts to limit the position of the bearing base 2 in the vertical direction. Connect and install the two limiting blocks 14 on one end of the corresponding set screws 12 respectively so that the two limiting blocks 14 are located on both sides of the bearing base 2.

[0025] Based on the above design, during operation, by moving the set screws 12 respectively to drive the limiting blocks 14 to move and adjust the position of the limiting blocks 14, so that the arc surface 141 of the limiting blocks 14 fits the side surface of the bearing base 2, thereby adjusting the coaxiality of the bearing base 2 and the main structure 4. Cooperate with the set screw nut 13 to fix the connection between the set screw 12 and the main board 111 of the base 11, prevent the set screw 12 from shifting in the horizontal direction relative to the corresponding main board 111, limit the position of the limiting blocks 14 in the horizontal direction, and fix the limiting blocks 14 by fasteners 15 to prevent the limiting blocks 14 from shifting in the vertical direction. The two limiting and anti-loosening modules 1 cooperate with each other to achieve stable limiting of the bearing base 2 in the horizontal direction, thereby realizing the limiting of the bearing 3. The bearing limiting and anti-loosening device is composed of two relatively arranged limiting and anti-loosening modules 1. One end of the set screw 12 of the limiting and anti-loosening module 1 is connected to the limiting block 14. By forming an arc surface 141 on the side of the limiting block 14 away from the set screw 12 that fits the side surface of the bearing base 2, the limiting block 14 is closely attached to the bearing base 2 to prevent loosening. It can effectively expand the contact area between the arc surface 141 of the limiting block 14 and the side surface of the bearing base 2, reduce the contact pressure of the bearing base 2, thereby ensuring the normal use of the bearing base 2. At the same time, use the double set screws 12 to tighten the limiting blocks 14, effectively ensuring the force strength of the limiting blocks 14 against the sliding of the bearing base 2, preventing the bearing base 2 from shifting due to excessive force during rotation, making the limiting of the bearing 3 stable and reliable, and avoiding damage to the bearing base 2. The structure is compact, simple and reliable, and the operation is stable.

[0026] Specifically, the base 11 further includes a support plate 112 which is vertically provided on a side of the main board 111 away from the limit block 14 to better fix the base 11 and define the position of the base 11. Preferably, the support plate 112 is located at the upper end of the main board 111. The support plate 112 and the main board 111 are integrally formed.

[0027] Specifically, the limit block 14 includes a bottom plate 142 and a limit plate 143 vertically provided on the bottom plate 142. One end of the setscrew 12 is connected to the limit plate 14. The arc surface 141 is formed on a side of the limit plate 143 away from the setscrew 12 to fit with the side surface of the bearing base 2. A fixing groove 144 for the fastener 15 to be provided is provided on the bottom plate 142. Wherein, the limit plate 143 can be located on a side of the bottom plate 142 away from the setscrew 12. A side of the limit plate 143 away from the setscrew 12 is flush with a side of the bottom plate 142 away from the setscrew 12. A side of the bottom plate 142 away from the setscrew 12 forms an arc surface for fitting with the side surface of the bearing base 2. The fastener 15 can be a screw. The screw passes through the fixing groove 144, and both ends of the screw are respectively fastened by fastening nuts 151 to define the position of the bottom plate 142, thereby defining the position of the limit block 14. Preferably, clip pieces 146 for defining the fastening nuts 151 are respectively provided on the front and rear sides of the bottom plate 142 at the fixing groove 144.

[0028] Specifically, in this embodiment, a support member 145 is connected between the limit plate 143 and the bottom plate 142 to support between the limit plate 143 and the bottom plate 142. Preferably, the number of the support members 145 is two and they are respectively provided on the front and rear sides of the bottom plate 142.

[0029] Specifically, in this embodiment, the support member 145 is a support plate in the shape of a right triangle, and two right-angled sides of the support plate are respectively connected to the limit plate 143 and the bottom plate 142. Of course, in some embodiments, the support member 145 can be a diagonal brace, and both ends of the diagonal brace are respectively connected to the limit plate 143 and the bottom plate 142.

[0030] In summary, a bearing limit and anti-loosening device of the present invention includes two relatively arranged limit and anti-loosening modules. One end of the set screw of the limit and anti-loosening module is connected to the limit block. By forming an arc surface that fits the side surface of the bearing base on the side of the limit block away from the set screw, the limit block is closely attached to the bearing base to prevent loosening. The contact area between the arc surface of the limit block and the side surface of the bearing base can be effectively enlarged, and the contact pressure of the bearing base can be reduced, thereby ensuring the normal use of the bearing base. At the same time, the limit block is tightened by using two set screws, effectively ensuring the force-bearing strength of the limit block against the sliding of the bearing base and preventing the displacement of the bearing base caused by excessive force during rotation, making the limit of the bearing stable and reliable, and avoiding damage to the bearing base. The structure is compact, simple and reliable, and the work is stable.
