Technical Field

[0001] This utility model belongs to the field of bearing housing technology, specifically relating to a stable bearing housing for automotive castings. Background Technology

[0002] Bearing housings, also called bearing boxes, are the outer support for shafts and bearings. They are widely used as important transmission components in machinery and equipment. Bearings also need support when they rotate, and the support required for bearing transmission is what we commonly call the bearing housing.

[0003] In the prior art, most bearing housings are usually installed using bolt sets. This can lead to instability at the connection between the bearing housing and the vehicle due to loosening of the bolt sets during use, causing the bearing housing to wobble. To address this problem, we propose a stable bearing housing for automotive castings. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 This utility model provides a stable bearing housing for automotive castings, including a fixing component 4, a bearing housing component 1 disposed above the fixing component 4, a B connecting component 3 disposed between the bearing housing component 1 and the fixing component 4, and an A connecting component 2 disposed on the bearing housing component 1.

[0028] The fixing component 4 includes a fixing base 41, the surface of which is provided with an insertion groove, and the insertion groove is provided with a sliding groove.

[0029] B connecting assembly 3 includes A snap-fit ​​rack 31, B snap-fit ​​rack 32 and spring 33. Spring 33 is installed in sliding groove. B snap-fit ​​rack 32 is slidably disposed in sliding groove and connected to the end of spring 33. A snap-fit ​​rack 31 is disposed on bearing seat assembly 1 and is disposed in insertion groove. A snap-fit ​​rack 31 is snapped with B snap-fit ​​rack 32.

[0030] Specifically, in actual use, by setting the A-type snap-fit ​​rack 31 on the lower bearing seat 11, and by slowly inserting the A-type snap-fit ​​rack 31 into the insertion groove and bringing it into contact with the B-type snap-fit ​​rack 32, the A-type snap-fit ​​rack 31 will squeeze the B-type snap-fit ​​rack 32 upon contact, thereby causing the B-type snap-fit ​​rack 32 to move into the sliding groove. Since a spring 33 is provided at one end of the B-type snap-fit ​​rack 32, after the A-type snap-fit ​​rack 31 is fully engaged with the B-type snap-fit ​​rack 32, the spring 33 will push the B-type snap-fit ​​rack 32, thereby enabling the B-type snap-fit ​​rack 32 to stably engage with the A-type snap-fit ​​rack 31.

[0031] In this embodiment, the bearing housing assembly 1 includes a lower bearing housing 11, an upper bearing housing 12, and a rotating bearing 14. The lower bearing housing 11 is disposed above the fixed base 41, the upper bearing housing 12 is disposed above the lower bearing housing 11, and the rotating bearing 14 is disposed between the lower bearing housing 11 and the upper bearing housing 12. The bearing housing assembly 1 also includes an automotive bearing 13, which is disposed within the rotating bearing 14.

[0032] Specifically, during use, the lower bearing housing 11 and the upper bearing housing 12 can be opened separately, and the rotating bearing 14 can be placed between the two, so that the car bearing 13 can be placed inside the rotating bearing 14 and thus the car bearing 13 can be fixed.

[0033] In this embodiment, the fixing component 4 also includes a buffer pad 42, which is disposed between the lower bearing seat 11 and the fixing seat 41. The surface of the buffer pad 42 is provided with a groove, and the opening position, size and shape of the groove are the same as those of the insertion groove.

[0034] Specifically, in actual use, in order to avoid the lower end of the lower bearing seat 11 colliding with the upper end of the fixed seat 41 and causing damage to both, a buffer pad 42 can be set between the two to buffer the lower bearing seat 11.

[0035] In this embodiment, a movable groove is provided on the lower bearing seat 11, and a rotating hole is provided in the movable groove. The rotating hole penetrates the surface of the lower bearing seat 11, and the A-type snap-fit ​​rack 31 is slidably disposed in the movable groove.

[0036] Specifically, in order to facilitate the subsequent disconnection between the lower bearing housing 11 and the fixed seat 41, the A-clamp rack 31 can be set in the movable groove and can slide. When disconnecting, simply move the A-clamp rack 31 horizontally.

[0037] In this embodiment, the B connecting assembly 3 further includes a ratchet 34, a ratchet 35, and a lead screw 36. The lead screw 36 is disposed in the rotating hole, the A engaging rack 31 is threaded onto the lead screw 36, the ratchet 34 is mounted on the lower bearing seat 11, and the ratchet 35 is mounted on the lead screw 36. The ratchet 34 and the ratchet 35 are engaged.

[0038] Specifically, to prevent the A-clamping rack 31 from moving during connection and causing instability, the A-clamping rack 31 can be threaded onto the lead screw 36. The A-clamping rack 31 can then be moved by rotating the lead screw 36. A ratchet 35 can then be installed on the lead screw 36, and a ratchet 34 can be installed on the lower bearing seat 11. The ratchet 34 engages with the ratchet 35, thus preventing the lead screw 36 from deflecting.

[0039] In this embodiment, the A connecting assembly 2 includes a connecting rod 21 and a bolt group 22. Fixing holes are provided on the surfaces of the lower bearing seat 11 and the upper bearing seat 12. The connecting rod 21 is disposed in the fixing hole, and the bolt group 22 is threadedly connected to the connecting rod 21.

[0040] Specifically, when connecting the lower bearing housing 11 and the upper bearing housing 12, the connecting rod 21 can be inserted into the fixing holes opened on both, and then the position of the connecting rod 21 can be fixed by the bolt group 22, so that the lower bearing housing 11 and the upper bearing housing 12 can be stably connected.

[0041] In this embodiment, the A connecting assembly 2 further includes a clamping member 23 and a threaded member 24. The clamping member 23 is sleeved on the connecting rod 21 and is positioned above the bolt assembly 22. The clamping member 23 includes a clamping portion and a threaded portion. The threaded member 24 is sleeved on the connecting rod 21 and is threaded onto the threaded portion.

[0042] Specifically, in order to prevent the bolt assembly 22 from deflecting and causing the connecting rod 21 to fall off, a clamping member 23 can be fitted onto the connecting rod 21 and connected to the threaded part through the threaded member 24, thereby squeezing the clamping part and allowing the clamping part to clamp the connecting rod 21, thus preventing the bolt assembly 22 from deflecting and the connecting rod 21 from falling off.

[0043] The working principle and usage process of this utility model are as follows: When installing the bearing housing assembly 1, the fixing assembly 4 can be stably connected to the vehicle first. Then, the bearing housing assembly 1 and the fixing assembly 4 can be stably connected through the B connecting assembly 3, thereby avoiding unstable connection during subsequent use, which would cause the bearing housing assembly 1 to shake. Then, the car bearing 13 can be stably set. Then, the lower bearing housing 11 and the upper bearing housing 12 can be stably connected through the A connecting assembly 2, thereby preventing the car bearing 13 from falling off during use.

[0044] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
