Description

Technical Field

[0001] This utility model belongs to the field of bearing housings, and specifically relates to a split vertical bearing housing. Background Technology

[0002] Bearing housings are important parts in mechanical equipment. They are generally used in conjunction with bearings. Their main function is to surround the outside of the bearing and fix the outer ring of the bearing so that the shaft connected to the inner ring can rotate normally. At the same time, they also provide support for the bearing and the shaft. Bearing housings are divided into integral bearing housings and split bearing housings.

[0003] Traditional split bearing housings consist of two housings, each with a semi-circular groove that mates with the bearing. The two housings are joined together to form a bearing hole, which is then fitted onto the bearing. The housings have flanges, and bolts pass through the flange holes to connect and secure the two housings. During operation, bearings generate significant vibrations. Because traditional split bearings are directly connected by bolts, the bolts are prone to loosening under prolonged vibration. If not regularly inspected, there is a risk of the bearing falling off, which can seriously affect equipment operation. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes a split vertical bearing housing. By setting a limiting component between the upper and lower connecting parts, vibration is resisted, thereby reducing the vibration intensity transmitted to the bolt, extending the bolt loosening cycle, and reducing the risk of bolt loosening.

[0005] The specific implementation scheme is as follows: a split vertical bearing housing, including an upper housing body, the upper housing body including an upper connecting part and an upper bearing fixing part; and also including a lower housing body, the lower housing body including a lower connecting part and a lower bearing fixing part;

[0006] The upper connecting part and the lower connecting part are detachably connected to fix the upper seat body and the lower seat body together. The upper bearing fixing part and the lower bearing fixing part are connected to form a bearing cavity for accommodating the bearing. A limiting member is provided between the upper connecting part and the lower connecting part.

[0007] Preferably, the limiting member includes a protrusion and a groove. The end of the upper connecting part that is connected to the upper bearing fixing part is the upper junction end, and the end of the lower connecting part that is connected to the lower bearing fixing part is the lower junction end. The groove is located at the upper junction end, and the protrusion is located at the lower junction end. The protrusion and the groove are engaged with each other.

[0008] The vibration of the bearing is first transmitted to the upper and lower junctions. The protrusions and the grooves engage with each other to prevent movement, thereby reducing the overall amplitude and increasing the closing strength between the upper and lower housings. This reduces the vibration intensity transmitted to the bolts and also increases the bearing capacity of the bearing housing.

[0009] Preferably, the lower bearing fixing part occupies 1 / 4-1 / 3 of the bearing cavity, that is, the upper bearing fixing part and the lower bearing fixing part are asymmetrically arranged. The asymmetrical arrangement will make the upper connecting part and the lower connecting part not be in the direct direction of the bearing centrifugal force. Before the vibration is transmitted to the limiting member, the upper bearing fixing part and the lower bearing fixing part themselves will resist and disperse the vibration. Then, after being resisted by the limiting member, the limiting member is prevented from bearing the direct transmission of centrifugal force and the load borne by the limiting member is reduced.

[0010] Preferably, the bottom contact surfaces of the slot and the protrusion are inclined from the horizontal position toward the lower seat body so that the bottom contact surfaces are perpendicular to the radial direction of the bearing cavity.

[0011] Vibration originates from the centrifugal force generated when the bearing rotates, acting on the inner wall of the bearing cavity. Since the bearing cavity is circular, the force is mostly radial. The bottom contact surface of the slot and the protrusion is perpendicular to the radial direction of the bearing cavity, which is more conducive to resisting the centrifugal force located in the first and second quadrants.

[0012] At the same time, the downward tilt angle will cause the upper bearing fixing part to move towards the lower bearing fixing part when under force, making the upper and lower connecting parts fit more tightly, playing a self-locking role and further preventing the bolts from loosening.

[0013] Preferably, both the upper and lower junctions are curved upwards from the horizontal direction.

[0014] The upper bearing fixing part occupies a large proportion of the entire bearing cavity. Therefore, in addition to the oblique upward force in the first and second quadrants, it is also subjected to the horizontal force. When the centrifugal force is in the horizontal direction, the junction of the upper and lower junctions is used to resist vibration. At this time, the bending will cause the upper junction to form an upward trend, which will then transmit the force to the limiting member, so that the limiting member can play a synergistic role in resisting vibration.

[0015] Alternatively, the lower bearing fixing part and the upper bearing fixing part can be set 1 / 1, and the protrusion can be set as a square protrusion, and the slot part can be set as a square hole to match the protrusion. This structure is easy to process, but the positions where the upper connecting part and / or the lower connecting part are connected are the direct force points of the upper bearing fixing part and / or the lower bearing fixing part. The direction of force transmission is the same as the direction of the limiting part. The force is directly transmitted to the limiting part, which increases the load on the limiting part, accelerates the wear of the limiting part, and shortens the service life of the limiting part.

[0016] Preferably, both the upper and lower connecting parts are provided with connecting holes, the two connecting holes are positioned correspondingly, and bolts are provided to pass through the two connecting holes to fix the upper and lower connecting parts.

[0017] Preferably, the connecting hole is elliptical, and the length of the connecting hole in the radial direction of the bearing cavity is greater than the length in the axial direction of the bearing cavity.

[0018] The elliptical connecting hole allows for a small amount of horizontal movement in the upper connecting part, providing a clearance for the limiting part to lock itself, and also buffering horizontal vibrations to some extent.

[0019] Preferably, the limiting member is located at the center of the upper and lower confluence ends, and the limiting members are provided on both sides of the bearing cavity, and the two limiting members are symmetrically arranged along the vertical diameter tangent of the bearing cavity.

[0020] The limiting component is located in the center position so that the supporting force on the left and right sides of the slot is the same, making it less prone to deformation.

[0021] Preferably, both the upper bearing fixing part and the lower bearing fixing part are provided with shoulders on both sides along the axial direction. The shoulders are arranged along the circumference and are used to prevent the bearing from moving axially along the bearing cavity, thereby preventing the bearing from falling off and protecting the bearing.

[0022] Preferably, the shoulder is provided with a top groove at the top of the upper bearing fixing part. The top groove is conducive to increasing the heat dissipation effect of the bearing cavity, and at the same time, it can reduce the production materials and reduce the production cost.

[0023] The beneficial effects of this utility model are as follows:

[0024] (1) The present invention uses the mutual contact between the slot and the protrusion to offset most of the vibration caused by the centrifugal force of the bearing, thereby increasing the bearing capacity of the bearing seat, extending the service life of the bearing seat, reducing the impact of vibration on the bolt, and reducing the risk of bolt loosening.

[0025] (2) The bottom surface of the slot and the protrusion of this utility model is set as a downward inclined surface. When the vibration is counteracted, it will form a downward movement trend and form a self-locking effect, making the upper connecting part and the lower connecting part fit more tightly and increasing the overall closing strength.

[0026] (3) The limiting component of this utility model adopts a concave-convex matching limiting method, which is convenient to assemble, simple to install, improves installation efficiency, and saves manpower.

[0027] (4) The extension direction of the upper connecting part / lower connecting part of this utility model is different from the force direction at the connection point with the upper bearing fixing part / lower bearing fixing part, so that the force borne by the limiting part is a component force in each direction, which reduces the load on the limiting part, extends the service life of the limiting part, and also improves the shock resistance.

[0040] Example 1

[0041] In one embodiment: a split vertical bearing housing is provided, such as Figure 1-5 As shown, it includes an upper seat 1, which includes an upper connecting part 11 and an upper bearing fixing part 12; it also includes a lower seat 2, which includes a lower connecting part 21 and a lower bearing fixing part 22.

[0042] The upper connecting part 11 is located on both sides of the upper bearing fixing part 12, and the lower connecting part 21 is located on both sides of the lower bearing fixing part 22;

[0043] The upper connecting part 11 and the lower connecting part 21 are detachably connected to fix the upper seat 1 and the lower seat 2 together. The upper bearing fixing part 12 and the lower bearing fixing part 22 are connected to form a bearing cavity 3 for accommodating the bearing. A limiting member 4 is provided between the upper connecting part 11 and the lower connecting part 21. A limiting member 4 is provided on both sides of the bearing cavity 3. The two limiting members 4 are symmetrically arranged along the vertical diameter tangent of the bearing cavity 3.

[0044] In this embodiment, the limiting member 4 includes a protrusion 41 and a slot 42. The end of the upper connecting part 11 connected to the upper bearing fixing part 12 is the upper junction end 111, and the end of the lower connecting part 21 connected to the lower bearing fixing part 22 is the lower junction end 211. The slot 42 is provided at the upper junction end 111, and the protrusion 41 is provided at the lower junction end 211. The protrusion 41 and the slot 42 are engaged.

[0045] The vibration of the bearing is first transmitted to the upper junction 111 and the lower junction 211. The protrusion 41 and the slot 42 engage with each other to prevent each other from moving, thereby reducing the overall amplitude and thus reducing the vibration intensity transmitted to the bolt.

[0046] In this embodiment, the lower bearing fixing part 22 occupies 1 / 4-1 / 3 of the bearing cavity 3, that is, the upper bearing fixing part 12 and the lower bearing fixing part 22 are asymmetrically arranged. The asymmetrical arrangement will cause the upper connecting part 11 and the lower connecting part 21 to be not in the direct direction of the bearing centrifugal force. Before the vibration is transmitted to the limiting member 4, the upper bearing fixing part 12 and the lower bearing fixing part 22 themselves will resist and disperse the vibration. Then, after being resisted by the limiting member 4, the limiting member 4 is prevented from bearing the direct transmission of centrifugal force, and the load borne by the limiting member 4 is reduced.

[0047] Furthermore, the bottom contact surfaces 43 of the slot portion 42 and the protrusion portion 41 are inclined from the horizontal position toward the lower seat body 2, so that the bottom contact surface 43 and the radial direction of the bearing cavity 3 are perpendicular.

[0048] The vibration originates from the centrifugal force generated when the bearing rotates and acts on the inner wall of the bearing cavity 3. Since the bearing cavity 3 is circular, the force is mostly radial. The bottom contact surface 43 of the slot 42 and the protrusion 41 is perpendicular to the radial direction of the bearing cavity 3, which is more conducive to resisting the centrifugal force located in the first and second quadrants.

[0049] At the same time, the downward tilt angle will cause the upper bearing fixing part 12 to move towards the lower bearing fixing part 22 when under force, so that the upper connecting part 11 and the lower connecting part 21 fit more tightly, playing a self-locking role and further preventing the bolts from loosening.

[0050] Furthermore, both the upper junction 111 and the lower junction 211 are bent upwards from the horizontal direction.

[0051] The upper bearing fixing part 12 occupies a large proportion of the entire bearing cavity 3. Therefore, in addition to the oblique upward force located in the first and second quadrants, it is also subjected to the horizontal force. When the centrifugal force is in the horizontal direction, the junction of the upper junction 111 and the lower junction 211 is used to resist vibration. At this time, the bending point will cause the upper junction 111 to form an upward trend, thereby transmitting the force to the limiting member 4, so that the limiting member 4 plays a cooperative role in resisting vibration.

[0052] Furthermore, both the upper connecting part 11 and the lower connecting part 21 are provided with connecting holes 23, the two connecting holes 23 are positioned opposite each other, and bolts are provided to pass through the two connecting holes 23 to fix the upper connecting part 11 and the lower connecting part 21.

[0053] Furthermore, the connecting hole 23 is elliptical, and the length of the connecting hole 23 in the radial direction of the bearing cavity 3 is greater than the length in the axial direction of the bearing cavity 3.

[0054] The elliptical connecting hole 23 allows the upper connecting part 11 to have a small amount of movement space in the horizontal direction, which provides a movement gap for the limiting part 4 to lock itself, and also buffers the horizontal vibration to a certain extent.

[0055] Furthermore, the limiting member 4 is located at the center of the upper junction 111 and the lower junction 211.

[0056] The limiting member 4 is located at the center position, so that the supporting force on both sides of the slot part 42 is the same, and it is not easy to deform.

[0057] Furthermore, both the upper bearing fixing part 12 and the lower bearing fixing part 22 are provided with shoulders 31 on both sides along the axial direction. The shoulders 31 are arranged along the circumference and are used to prevent the bearing from moving along the axial direction of the bearing cavity 3, so as to prevent the bearing from falling off and to protect the bearing.

[0058] Preferably, the shoulder 31 is provided with a top groove 32 at the top of the upper bearing fixing part 12. The top groove 32 is beneficial to increase the heat dissipation effect of the bearing cavity 3, and at the same time, it can reduce the production materials and reduce the production cost.

[0059] The upper seat 1 and lower seat 2 are fitted onto the bearing, which is located inside the bearing cavity 3. Bolts pass through the connecting hole 23 to connect and fix the upper seat 1 and lower seat 2. When the bearing is running, centrifugal force continuously acts on the upper seat 1 and lower seat 2. The limiting member 4 acts to block the vibration caused by the centrifugal force. The bearing cavity 3 is divided into four quadrants with the center as the base point. The first and fourth quadrants are to the left, and vice versa. When the vibration generated by the centrifugal force in the first quadrant is canceled out by the bottom contact surface 43 of the right protrusion 41 and the slot 42, the bearing cavity 3 is in a relatively stable position. The inclined surface causes the upper seat 1 to have a downward movement tendency, forming a self-locking mechanism; the centrifugal force in the second quadrant is offset by the bottom contact surface 43 of the left protrusion 41 and the slot 42; the centrifugal force in the third quadrant acting on the upper seat 1 is offset by the contact point between the left upper junction 111 and the lower junction 211, and the centrifugal force acting on the lower seat 2 is offset by the right limiting member 4; the centrifugal force in the fourth quadrant acting on the upper seat 1 is offset by the contact point between the right upper junction 111 and the lower junction 211, and the centrifugal force acting on the lower seat 2 is offset by the left limiting member 4.

[0061] In another embodiment: a split vertical bearing housing is provided, including an upper housing 1, which includes an upper connecting part 11 and an upper bearing fixing part 12; and a lower housing 2, which includes a lower connecting part 21 and a lower bearing fixing part 22.

[0062] The upper connecting part 11 is located on both sides of the upper bearing fixing part 12, and the lower connecting part 21 is located on both sides of the lower bearing fixing part 22;

[0063] The upper connecting part 11 and the lower connecting part 21 are detachably connected to fix the upper seat 1 and the lower seat 2 together. The upper bearing fixing part 12 and the lower bearing fixing part 22 are connected to form a bearing cavity 3 for accommodating the bearing. A limiting member 4 is provided between the upper connecting part 11 and the lower connecting part 21. A limiting member 4 is provided on both sides of the bearing cavity 3. The two limiting members 4 are symmetrically arranged along the vertical diameter tangent of the bearing cavity 3.

[0064] The limiting member 4 includes a protrusion 41 and a slot 42. The upper connecting part 11 is connected to one end of the upper bearing fixing part 12 as the upper junction end 111, and the lower connecting part 21 is connected to one end of the lower bearing fixing part 22 as the lower junction end 211. The slot 42 is provided at the upper junction end 111, and the protrusion 41 is provided at the lower junction end 211. The protrusion 41 and the slot 42 are engaged.

[0065] In this embodiment, the lower bearing fixing part 22 and the upper bearing fixing part 1 / 1 are provided. The protrusion 41 can be set as a square protrusion, and the slot part 42 is set as a square hole to cooperate with the protrusion 41. In this scheme, the positions connected by the upper connecting part 11 and / or the lower connecting part 21 are the direct force points of the upper bearing fixing part 12 and / or the lower bearing fixing part 22. The direction of force transmission is the same as the direction of the limiting part 4. The force is directly transmitted to the limiting part 4, which increases the load at the limiting part 4, accelerates the wear at the limiting part 4, and shortens the service life of the limiting part 4. However, this structure is easy to process and can also be used as an implementation method.
