Description

Technical Field

[0001] This invention relates to the field of bearing housing technology, and more particularly to a suspended adaptive bearing housing. Background Technology

[0002] Suspended bearing housings are a type of bearing housing with a special suspension support that can accept comprehensive loads. They are characterized by their compact structure, flexible rotation, and convenient installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is what is commonly referred to as the bearing housing. As an important category of bearing housings, suspended bearing housings are widely used.

[0003] The bearing housing can be referenced from patent CN115585193B, which includes a mounting plate. A first support seat and a second support seat are respectively located on the top two sides of the mounting plate. The first support seat is fixedly connected to the top of the mounting plate. A groove is formed on the bottom of the second support seat corresponding to the top of the mounting plate, and the bottom of the second support seat is slidably installed in the groove. An adjusting screw is vertically inserted through the groove on the side away from the first support seat. By providing a first clamping device and a second clamping device, when fixing the bearing, the first clamping device can cooperate with the second clamping device to complete the fixing operation of the bearing from both sides, thus ensuring that the middle of the bearing is not obstructed. This, combined with the heat dissipation device, can effectively improve the heat dissipation effect of the bearing. Since the position of the second clamping device is adjustable, it can cooperate with the first clamping device to achieve locking operations on bearings of the same diameter but different widths.

[0004] Currently, suspended bearing housings generally adopt an integrated structural design. After installation and positioning, their spatial position is not adjustable. When there is a slight coaxiality deviation between the bearing and the supported rotating parts, the entire assembly must be disassembled and reassembled. This not only consumes a lot of time, but may also affect the assembly accuracy of the equipment due to repeated disassembly and reassembly, significantly reducing maintenance efficiency and operational reliability. Summary of the Invention

[0005] This invention relates to a suspended adaptive bearing housing, which solves the problem that existing suspended bearing housings generally adopt an integrated structural design, and their spatial position is not adjustable after installation and positioning. When there is a slight coaxiality deviation between the bearing and the supported rotating part, the entire assembly must be disassembled and reassembled, which not only consumes a lot of time, but may also affect the assembly accuracy of the equipment due to repeated disassembly and reassembly, significantly reducing maintenance efficiency and operational reliability.

[0006] In a first aspect, the present invention provides a suspended adaptive bearing housing, specifically comprising: a suspension support base, a lifting connecting frame, a bearing assembly base, an adjusting screw, a movable pin, a movable crossbar, and a return spring; the suspension support base is fixedly connected to a mounting surface by bolts, the lifting connecting frame is connected to the bottom of the suspension support base, the adjusting screw is connected inside the suspension support base and is connected to the lifting connecting frame; the bearing assembly base is connected to the bottom of the lifting connecting frame; the movable pin is connected to the top of the suspension support base and is connected to the top of the adjusting screw; the movable crossbar is connected inside the lifting connecting frame and is connected to the top of the bearing assembly base, and a return spring is provided between the movable crossbar and the lifting connecting frame.

[0007] Furthermore, two vertical guide rods are symmetrically arranged on the outside of the suspension support base, and two top guide holes are symmetrically arranged on the top of the lifting frame. The vertical guide rods slide through the top guide holes provided in the lifting frame, and the lifting frame is moved and guided by the sliding cooperation between the vertical guide rods and the top guide holes.

[0008] Furthermore, the adjusting screw is rotatably connected to the suspension support seat, and a threaded hole is provided in the middle of the top of the lifting frame. The adjusting screw is threaded into the threaded hole provided in the lifting frame. According to the bearing installation requirements, the adjusting screw can be rotated by a wrench, and the adjusting screw can drive the lifting frame to move up and down to adjust and change the height of the bearing assembly seat.

[0009] Furthermore, the top of the suspension support is provided with a guide hole, and the movable pin slides through the guide hole provided in the suspension support. The two sides of the movable pin are flat. A return spring is fitted on the outside of the movable pin. The top of the return spring contacts the suspension support and the bottom of the return spring contacts the movable pin. The guide hole guides the movable pin to move and prevents the movable pin from rotating. The return spring also provides an elastic reset effect for the movable pin.

[0010] Furthermore, a limiting block is provided around the bottom of the movable pin, and a limiting groove is provided around the top of the adjusting screw. The limiting block is inserted into the limiting groove provided on the adjusting screw. After the bearing assembly seat is adjusted to the required height, the adjusting screw stops rotating and the movable pin is released. The movable pin moves downward and resets under the influence of the return spring, so that the limiting block is inserted into the limiting groove. The adjusting screw is locked and fixed by the movable pin, preventing the adjusting screw from rotating, and indirectly fixing the height of the bearing assembly seat.

[0011] Furthermore, the bearing assembly seat is rotatably connected to the lifting frame, and the bearing assembly seat can rotate from 0 to 360 degrees. When the angle of the bearing assembly seat deviates from that of the mechanical rotating body, the bearing assembly seat is adaptively rotated and adjusted according to the different angles of the mechanical rotating body to change the orientation of the bearing assembly seat.

[0012] Furthermore, the lifting frame is provided with side sliding holes on both sides, and the two ends of the movable crossbar are slidably connected to the side sliding holes provided in the lifting frame, so as to guide the movement of the movable crossbar through the side sliding holes.

[0013] Furthermore, the bearing assembly seat has a positioning groove surrounding the top, and a positioning block surrounding the bottom of the movable crossbar, the positioning block being inserted into the positioning groove provided in the bearing assembly seat.

[0014] Furthermore, the bottom of the lifting frame is symmetrically provided with fixed pull holes, and the bottom end of the reset spring is connected to the fixed pull hole provided in the lifting frame. Both ends of the movable crossbar are provided with movable pull holes, and the top end of the reset spring is connected to the movable pull hole provided in the movable crossbar. After the bearing assembly seat is rotated and adjusted to the required angle, the movable crossbar is released. Under the influence of the tension of the reset spring, the movable crossbar moves downward to reset, so that the positioning block is inserted into the positioning groove, and the bearing assembly seat is limited and fixed by the movable crossbar.

[0015] This invention provides a suspended adaptive bearing housing, which has the following beneficial effects:

[0016] In use, this invention uses a vertical guide rod that slides into the top guide hole to guide the movement of the lifting frame. Depending on the bearing installation requirements, a wrench can be used to rotate the adjusting screw, which in turn moves the lifting frame up and down to adjust the height of the bearing assembly, thus better meeting the needs of bearing suspension support at different heights. A guide hole guides the movement of the movable pin, preventing its rotation, and a return spring provides elastic reset for the pin. Once the bearing assembly is adjusted to the desired height, the adjusting screw stops rotating, releasing the movable pin. Under the force of the return spring, the movable pin moves downwards to reset, inserting a limit block into a limit groove. The movable pin then locks the adjusting screw, preventing its rotation and indirectly fixing the height of the bearing assembly, ensuring stability at its designated height.

[0017] Furthermore, when the angle of the bearing assembly deviates from that of the rotating mechanical body, the bearing assembly is adaptively rotated and adjusted according to the different angles of the rotating mechanical body, changing the orientation of the bearing assembly to better meet the suspension support requirements of the rotating mechanical body under different angle conditions, thus possessing extremely strong versatility. The movable crossbar is guided by the side sliding hole, and the return spring provides an elastic reset effect for the movable crossbar. After the bearing assembly is rotated and adjusted to the required angle, the movable crossbar is released, and under the influence of the return spring, it moves downward to reset, allowing the positioning block to insert into the positioning groove. The movable crossbar limits and fixes the bearing assembly, preventing the bearing assembly from rotating and ensuring the stability of the bearing assembly under its angle condition.

Two vertical guide rods 101 are symmetrically arranged on the outside of the suspension support 1, and two top guide holes 201 are symmetrically arranged on the top of the lifting frame 2. The vertical guide rods 101 slide through the top guide holes 201 provided in the lifting frame 2. The adjusting screw 4 is rotatably connected to the suspension support 1. A threaded hole 202 is provided in the middle part of the top of the lifting frame 2, and the adjusting screw 4 is threadedly connected to the threaded hole 202 provided in the lifting frame 2. The lifting frame 2 is moved and guided by the sliding cooperation between the vertical guide rods 101 and the top guide holes 201. According to the bearing installation requirements, the adjusting screw 4 can be rotated by a wrench, and the adjusting screw 4 can drive the lifting frame 2 to move up and down to adjust the height of the bearing mounting seat 3, thereby better meeting the needs of bearing suspension support at different heights.

[0042] In this embodiment of the invention, a guide hole 102 is provided at the top of the suspension support 1, and the movable pin 5 slides through the guide hole 102 provided in the suspension support 1. The movable pin 5 is planar on both sides. A return spring 6 is fitted on the outside of the movable pin 5. The top of the return spring 6 contacts the suspension support 1, and the bottom of the return spring 6 contacts the movable pin 5. A limit block 501 is provided around the bottom of the movable pin 5, and a limit groove 401 is provided around the top of the adjusting screw 4. The limit block 501 is inserted into the limit groove 401 provided in the adjusting screw 4.

[0043] Using the above technical solution, the movable pin 5 is guided by the guide hole 102 to prevent it from rotating, and the return spring 6 provides an elastic reset effect for the movable pin 5. After the bearing assembly 3 is adjusted to the required height, the adjusting screw 4 stops rotating and the movable pin 5 is released. Under the influence of the return spring 6, the movable pin 5 moves downward to reset, so that the limiting block 501 is inserted into the limiting groove 401. The movable pin 5 locks and fixes the adjusting screw 4, preventing it from rotating, and indirectly fixing the height of the bearing assembly 3, ensuring the stability of the bearing assembly 3 at its current height.

[0044] In this embodiment of the invention, the bearing assembly seat 3 is rotatably connected to the lifting frame 2, and the rotation angle of the bearing assembly seat 3 is 0~360 degrees;

[0045] By adopting the above technical solution, when the angle of the bearing assembly 3 deviates from that of the mechanical rotating body, the bearing assembly 3 is adaptively rotated and adjusted according to the different angles of the mechanical rotating body, thereby changing the orientation of the bearing assembly 3 and better meeting the suspension support requirements of the mechanical rotating body under different angle conditions, thus possessing extremely strong versatility.

[0046] In Example 2, based on Example 1, the lifting frame 2 has side sliding holes 203 on both sides, and the two ends of the movable crossbar 7 are slidably connected to the side sliding holes 203 provided in the lifting frame 2. The bearing assembly seat 3 has a positioning groove 301 around its top, and the movable crossbar 7 has a positioning block 701 around its bottom. The positioning block 701 is inserted into the positioning groove 301 provided in the bearing assembly seat 3. The lifting frame 2 has fixed pull holes 204 symmetrically provided at its bottom. The bottom end of the return spring 8 is connected to the fixed pull hole 204 provided in the lifting frame 2. The movable crossbar 7 has movable pull holes 702 at both ends, and the top end of the return spring 8 is connected to the movable pull hole 702 provided in the movable crossbar 7.

[0047] Using the above technical solution, the movable crossbar 7 is guided by the side sliding hole 203, and the reset spring 8 provides an elastic reset effect for the movable crossbar 7. After the bearing assembly seat 3 is rotated and adjusted to the required angle, the movable crossbar 7 is released. Under the influence of the tension of the reset spring 8, the movable crossbar 7 moves downward and resets, so that the positioning block 701 is inserted into the positioning groove 301. The movable crossbar 7 limits and fixes the bearing assembly seat 3, preventing the bearing assembly seat 3 from rotating and ensuring the stability of the bearing assembly seat 3 at the angular state.

[0048] The working principle of this embodiment is as follows: First, the suspension support 1 is fixedly connected to the mounting surface with bolts. According to the bearing installation requirements, the movable pin 5 is pulled up, the return spring 6 contracts under force, and the limit block 501 separates from the limit groove 401, releasing the locking screw 4. The adjusting screw 4 is then rotated using a wrench, causing the lifting frame 2 to move up and down for adjustment, changing the height of the bearing assembly 3 to better meet the needs of bearing suspension supports at different heights. After the bearing assembly 3 is adjusted to the required height, the adjusting screw 4 stops rotating, and the movable pin 5 is released. The movable pin 5 moves downwards under the push of the return spring 6, resetting the limit block 501 into the limit groove 401. The movable pin 5 locks the adjusting screw 4, preventing its rotation and indirectly fixing the height of the bearing assembly 3. The stability of the bearing assembly 3 at its current height is ensured. When the angle of the bearing assembly 3 deviates from that of the rotating mechanical body, the movable crossbar 7 moves upward, the return spring 8 is stretched, and the positioning block 701 separates from the positioning groove 301, releasing the bearing assembly 3 from its limit. The bearing assembly 3 is adaptively rotated and adjusted according to the angle of the rotating mechanical body to change its orientation and better meet the suspension support requirements of the rotating mechanical body at different angles. After the bearing assembly 3 is rotated to the required angle, the movable crossbar 7 is released. Under the influence of the return spring 8, the movable crossbar 7 moves downward to reset, allowing the positioning block 701 to insert into the positioning groove 301. The movable crossbar 7 then limits and fixes the bearing assembly 3, preventing it from rotating and ensuring its stability at its current angle.
