Description

Technical Field

[0001] This utility model belongs to the technical field of bearing accessories, and more specifically, it relates to a split-type adjustable bearing housing. Background Technology

[0002] Bearing housings are key components in mechanical structures that fix and support bearings, providing a stable mounting reference for the bearings and transmitting the loads (radial, axial, or combined loads) borne by the bearings to the equipment frame or foundation. Split bearing housings, as a type of bearing housing, allow for direct installation and removal of bearings simply by removing the top cover, making them particularly suitable for scenarios with long shaft systems and limited installation and removal space. Existing split bearing housings generally consist of a base, a top cover, a mounting plate for connecting to the equipment, and bolt holes drilled in the mounting plate.

[0003] Existing application number: CN202122987817.0, this utility model discloses a split bearing housing, including a base, a lower seat body disposed in the middle of the top of the base, an upper seat body disposed on the top of the lower seat body, a connecting seat A and a connecting seat B respectively disposed on both sides of the lower seat body and the upper seat body, and the connecting seat A and the connecting seat B are mutually adapted, and dustproof grooves are provided on the inner sides of both ends of the lower seat body and the upper seat body; this utility model provides bearing grooves inside the lower seat body and the upper seat body, and steel strip grooves inside the bearing grooves, and by embedding a fastening steel strip inside the steel strip groove, the bearing installed inside the bearing groove is further clamped and fixed by the fastening steel strip, thereby increasing the friction between the two, and by tightening the fastening bolts to compress the fastening steel strip, so that the fastening steel strip is tightly attached to the outer side of the bearing inside the bearing groove, thereby improving the stability of the bearing outer ring and ensuring the normal operation of the bearing.

[0004] Based on the above, in order to provide a certain lateral adjustment margin, the bolt holes of the split bearing housing are mostly designed with straight slots. After the bolt passes through the hole, it is fixed to the equipment only by the clamping force. After the equipment has been running for a long time, this structure is prone to displacement due to vibration. Under the continuous force of long-term vibration of the equipment, the fixing bolts are also prone to gradually reverse and loosen. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a split-type adjustable bearing housing. To solve the problem that, in order to provide a certain lateral adjustment margin, the bolt holes of split-type bearing housings often adopt a straight groove design. After the bolt passes through the hole, it is fixed to the equipment only by the clamping force. After the equipment has been running for a long time, this structure is prone to overall positional displacement due to vibration. Under the continuous force of long-term vibration of the equipment, the fixing bolts are also prone to gradually reverse and loosen.

[0006] The purpose and function of this utility model of a split-type adjustable bearing seat are achieved by the following specific technical means:

[0007] A split-type adjustable bearing housing includes a top cover, a base, a mounting plate, sliding blocks, bolt seats, bolt holes, fixing bolts, anti-displacement components, and anti-loosening components. The base is fixedly connected to the bottom of the top cover by bolts. The mounting plate is fixedly connected to the bottom of the base. Two sliding blocks are provided, and the two sliding blocks are slidably connected inside the mounting plate. Two bolt seats are provided, and the two bolt seats are fixedly connected to the outside of the two sliding blocks. Two bolt holes are provided, and the two bolt holes are respectively located inside the two bolt seats. Two fixing bolts are provided, and the two fixing bolts are respectively threaded into the two bolt holes. The anti-displacement components are located inside the mounting plate. Two sets of anti-loosening components are provided, and the two sets of anti-loosening components are respectively located inside the two bolt seats.

[0008] Furthermore, the anti-displacement component includes: an adjustment knob and a transmission worm gear; the adjustment knob is rotatably connected to the front of the mounting plate; the transmission worm gear is coaxially fixedly connected to the rear end of the adjustment knob.

[0009] Furthermore, the anti-displacement component also includes: a first drive shaft and a drive worm gear; the first drive shaft is rotatably connected inside the mounting plate; the drive worm gear is coaxially fixedly connected to the top of the first drive shaft, and the drive worm gear meshes with the drive worm.

[0010] Furthermore, the anti-displacement component also includes: an adjusting gear, a connecting rod, and an adjusting rack; the adjusting gear is coaxially fixedly connected to the bottom of the first transmission shaft; two connecting rods are provided, and the two connecting rods are respectively fixedly connected to the inner sides of two sliding blocks; two adjusting racks are provided, and the two adjusting racks are respectively fixedly connected to the inner sides of two connecting rods, and the two adjusting racks respectively mesh with the adjusting gear.

[0011] Furthermore, the anti-loosening component includes: a pressing plate and a positioning post; the pressing plate is slidably connected inside the bolt seat; and the positioning post is fixedly connected above the pressing plate.

[0012] Furthermore, the anti-loosening component also includes: a return spring, a positioning plate, and positioning holes; the top of the return spring is fixedly connected to the bottom of the pressing plate, and the bottom of the return spring is fixedly connected to the inside of the bolt seat; the positioning plate is coaxially fixedly connected to the top of the fixing bolt; multiple positioning holes are provided, and the multiple positioning holes are arranged in a circumferential array inside the positioning plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, bolt holes are made in the bolt seats. The positions of the two bolt seats are adjusted by setting anti-displacement components, providing a certain lateral adjustment margin. This allows the bolt holes that match the fixing bolts to be precisely aligned with the bolt slots of the equipment, while preventing the bolt seats from being displaced laterally by equipment vibration.

[0015] Secondly, by setting a positioning post inside the bolt seat, in conjunction with the positioning plate on the top of the fixing bolt, the fixing bolt and the bolt seat are limited, preventing the fixing bolt from turning back and loosening under long-term equipment vibration, thus reducing the risk of equipment failure caused by loose fixing bolts.

[0016] This invention achieves precise alignment between the bolt seat and the bolt groove of the equipment through the anti-displacement component, effectively avoiding the overall positional shift caused by equipment vibration after connection, significantly enhancing the structural stability after installation. At the same time, the mechanical limiting structure of the anti-loosening component provides reliable constraint on the fixing bolts, eliminating the phenomenon of reverse loosening caused by continuous vibration during long-term use, greatly improving the fastening reliability of the fixing bolts, thereby ensuring that the bearing seat maintains a stable connection with the equipment during long-term operation.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example 1:

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] This utility model provides a split adjustable bearing housing, including an upper cover 1, a base 2, a mounting plate 3, sliding blocks 4, bolt seats 5, bolt holes 501, fixing bolts 9, and an anti-displacement component; the base 2 is fixedly connected to the lower part of the upper cover 1 by bolts; the mounting plate 3 is fixedly connected to the lower part of the base 2; two sliding blocks 4 are provided, and the two sliding blocks 4 are slidably connected inside the mounting plate 3; two bolt seats 5 are provided, and the two bolt seats 5 are fixedly connected to the outer parts of the two sliding blocks 4; two bolt holes 501 are provided, and the two bolt holes 501 are respectively provided inside the two bolt seats 5; two fixing bolts 9 are provided, and the two fixing bolts 9 are respectively threaded into the two bolt holes 501; the anti-displacement component is provided inside the mounting plate 3.

[0027] The anti-displacement component includes: an adjustment knob 6 and a transmission worm gear 601; the adjustment knob 6 is rotatably connected to the front of the mounting plate 3; the transmission worm gear 601 is coaxially fixedly connected to the rear end of the adjustment knob 6.

[0028] The anti-displacement component also includes: a first drive shaft 7 and a drive worm gear 701; the first drive shaft 7 is rotatably connected inside the mounting plate 3; the drive worm gear 701 is coaxially fixedly connected to the top of the first drive shaft 7, and the drive worm gear 701 meshes with the drive worm 601.

[0029] The anti-displacement component also includes: an adjusting gear 702, a connecting rod 8, and an adjusting rack 801; the adjusting gear 702 is coaxially fixedly connected to the bottom of the first transmission shaft 7; two connecting rods 8 are provided, and the two connecting rods 8 are respectively fixedly connected to the inner side of the two sliding blocks 4; two adjusting racks 801 are provided, and the two adjusting racks 801 are respectively fixedly connected to the inner side of the two connecting rods 8, and the two adjusting racks 801 mesh with the adjusting gear 702 respectively.

[0030] The specific usage and function of this embodiment are as follows: In use, first connect the equipment shaft, bearing, upper cover 1 and base 2. Then, according to the reserved bolt slots on the equipment, rotate the adjustment knob 6. The worm gear transmission mechanism formed by the meshing of the transmission worm 701 and the transmission worm 601 drives the first transmission shaft 7 to rotate. The first transmission shaft 7 drives the two connecting rods 8 and the two sliding blocks 4 to slide outwards simultaneously through the gear and rack transmission mechanism formed by the meshing of the two adjusting racks 801 and the adjusting gears 702 respectively. This causes the two bolt seats 5 to move outwards simultaneously. When the two bolt holes 501 are aligned with the two reserved bolt slots on the equipment, the fixing bolts 9 can be installed. Compared with the traditional straight slot-shaped bolt holes 501, the mounting plate 3 is less likely to be displaced by equipment vibration after being fixed. Example 2:

[0031] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown, it also includes anti-loosening components, with two sets of anti-loosening components, which are respectively installed inside the two bolt seats 5.

[0032] The anti-loosening component includes: a pressing plate 10 and a positioning post 1001; the pressing plate 10 is slidably connected inside the bolt seat 5; and the positioning post 1001 is fixedly connected above the pressing plate 10.

[0033] The anti-loosening component also includes: a return spring 1002, a positioning plate 11, and positioning holes 1101; the top of the return spring 1002 is fixedly connected to the bottom of the pressing plate 10, and the bottom of the return spring 1002 is fixedly connected to the inside of the bolt seat 5; the positioning plate 11 is coaxially fixedly connected to the top of the fixing bolt 9; multiple positioning holes 1101 are provided, and the multiple positioning holes 1101 are arranged in a circumferential array inside the positioning plate 11.

[0034] The specific usage and function of this embodiment: Before installing the fixing bolt 9, manually press the pressing plate 10 downwards so that the positioning post 1001 is completely retracted into the bolt seat 5. Then, use a wrench or other tools to rotate the fixing bolt 9. When the pressing plate 10 is about to contact the top of the bolt seat 5, release the pressing plate 10. Under the rebound action of the return spring 1002, the pressing plate 10 and the positioning post 1001 move upwards. Then, slightly rotate the fixing bolt 9 left and right so that the positioning post 1001 can pass through the nearest positioning hole 1101, thereby restricting the position of the positioning plate 11 and the fixing bolt 9 and preventing the fixing bolt 9 from being reversed and loosened due to long-term equipment vibration.
