Description

Technical Field

[0001] This utility model relates to the field of bearing housings, and in particular to an anti-slip bearing housing. Background Technology

[0002] Bearing housings are crucial components used to install and secure bearings, and their stability directly affects the bearing's operational accuracy and the overall performance of the equipment. During equipment operation, factors such as vibration and load changes can easily cause bearing housings to shift or slip, which can not only affect the normal operation of the equipment but also potentially lead to safety hazards. Traditional bearing housings lack anti-slip structures on the bottom, resulting in instability during use.

[0003] While some existing bearing housings offer some anti-slip functionality, their anti-slip structures are typically quite simple, relying solely on a bottom anti-slip pad or simple mechanical fixation. This results in limited anti-slip effectiveness and poor adaptability to different installation scenarios, making it difficult to meet the installation requirements of high-precision equipment. Therefore, a bearing housing with superior anti-slip performance and greater adaptability is needed. Utility Model Content

[0004] The technical solution adopted by this utility model to solve its technical problem is: an anti-slip bearing seat, including a top cover and a base; the top cover is installed on the top of the base, and a bearing mounting hole is provided in the center of the top cover, and a bearing is installed in the bearing mounting hole; the base is provided with bolt positioning holes, and positioning bolts are installed in the bolt positioning holes; the top surface of the base is provided with two pressing mechanisms symmetrically distributed along the center line of the base, and the pressing mechanism is composed of a first support rod, a first hinge support, a second hinge support, a second support rod, a third hinge support, a pressure plate, and angle fastening bolts; one end of the first support rod is... The first hinge support is connected to the top surface of the base. The other end of the first support rod is hinged to one end of the second support rod via the second hinge support. The other end of the second support rod is hinged to the pressure plate via the third hinge support. The first, second, and third hinge supports are all equipped with angle fastening bolts to fix the hinge angle. The top surface of the base is provided with two screw holes symmetrically distributed along the center line of the base. The screw holes are connected to a groove located on the bottom surface of the base. A suction cup is provided in the groove. The top of the suction cup is rotatably connected to a screw rod via a rotating seat. The screw rod passes through the screw hole and the top of the screw rod is connected to a handle.

[0005] Furthermore, both the first and second support rods are telescopic rod structures composed of a mother rod, a daughter rod, and length-fixing bolts. One end of the mother rod is telescopically connected to the daughter rod, and the side wall of the mother rod is provided with fixing bolts to fix the telescopic length of the daughter rod. By adjusting the length and angle of the first and second support rods, the pressure plate can contact and press against other fixed objects on the side of the bearing seat, thereby further securing the position of the bearing seat.

[0006] Furthermore, the mother rod of the first support rod is hinged to the top surface of the base through the first hinge support, the son rod of the first support rod is hinged to the son rod of the second support rod through the second hinge support, and the mother rod of the second support rod is hinged to the pressure plate through the third hinge support.

[0007] Compared with the prior art, the beneficial effects of this utility model are: (1) The clamping mechanism on the top surface of the base is connected by a multi-hinged support rod structure, which can flexibly adjust the angle and length of the first and second support rods, so that the pressure plate can adapt to the position and shape of the surrounding fixed objects in different installation scenarios and achieve tight contact with the surrounding components. This adjustable lateral clamping force can effectively limit the horizontal displacement of the bearing seat, make up for the deficiency of insufficient lateral constraint when the traditional bearing seat is fixed by bolts alone, especially when the equipment vibrates or the load changes, it can reduce the risk of displacement caused by lateral sway. The first and second support rods adopt a telescopic rod structure. Through the cooperation of the mother rod, the daughter rod and the fastening bolts, the length of the support rod can be precisely adjusted, further improving the fit between the pressure plate and the surrounding fixed objects, ensuring that the clamping force is uniform and stable, and avoiding the reduction of anti-slip effect due to size mismatch.

[0008] (2) The suction cup in the groove on the bottom of the base is linked to the handle via a screw. Rotating the handle can raise and lower the screw, thereby controlling the contact pressure between the suction cup and the mounting surface. When the suction cup is pressurized and air is expelled, it can use atmospheric pressure to tightly adhere to the mounting surface, forming an additional longitudinal fixing force. This, together with the positioning bolts in the bolt positioning holes, forms a double longitudinal fixing system of bolts and suction cups, solving the problem of insufficient stability caused by the lack of anti-slip structure at the bottom of traditional bearing seats or the reliance on only a single anti-slip pad. The suction cup and the screw are connected by a rotating seat, so that the screw does not drive the suction cup to rotate when it rotates, ensuring that the suction cup is always in a flat state and in contact with the mounting surface, improving the reliability of adsorption. At the same time, the connection design between the screw hole and the groove provides stable support for the screw, ensuring that the pressure adjustment of the suction cup is precise and controllable.

[0009] (3) The combination of multi-angle adjustment of the clamping mechanism with the extension and retraction function of the support rod and the adjustable pressure design of the suction cup enables the bearing seat to adapt to different installation surfaces such as smooth metal and composite materials, as well as complex scenarios with diverse layouts of surrounding components, thus solving the problem of poor adaptability of existing anti-slip bearing seats. The synergistic effect of transverse clamping and longitudinal adsorption constructs a three-dimensional anti-slip fixing system, which can effectively disperse stress under dynamic working conditions such as high-frequency vibration and sudden load changes in equipment, reduce the stress load on a single structure, reduce the risk of bolt loosening and component wear, and provide a reliable guarantee for the stable operation of high-precision equipment.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0014] Reference Figure 1-3This embodiment provides an anti-slip bearing seat, including a top cover 1 and a base 2; the top cover 1 is fixedly installed on the top of the base 2, and a bearing mounting hole is provided in the center of the top cover 1, with a bearing 3 installed in the bearing mounting hole; the base 2 is provided with bolt positioning holes, with positioning bolts 4 installed in the bolt positioning holes; the top surface of the base 2 is provided with two pressing mechanisms symmetrically distributed along the center line of the base 2, the pressing mechanism consisting of a first support rod 5, a first hinge support 6, a second hinge support 7, a second support rod 8, a third hinge support 9, a pressure plate 10, and an angle fastening bolt 11; one end of the first support rod 5 is hinged to the top surface of the base 2 through the first hinge support 6, the other end of the first support rod 5 is hinged to one end of the second support rod 8 through the second hinge support 7, and the other end of the second support rod 8 is hinged to the third hinge support 9. The hinge support 9 is hinged to the pressure plate 10. The first hinge support 6, the second hinge support 7 and the third hinge support 9 are all provided with angle fastening bolts 11 to fix the hinge angle. When the angle fastening bolts 11 are loosened counterclockwise, the angle of the hinge support can be freely adjusted. When the angle fastening bolts 11 are tightened clockwise, the angle of the hinge support is locked. The top surface of the base 2 is provided with two screw holes 12 symmetrically distributed along the center line of the base 2. The screw holes 12 are connected to the groove 13 located on the bottom surface of the base 2. The groove 13 is provided with a suction cup 14. The top of the suction cup 14 is connected to the rotating seat 17 by bolts. The top of the rotating seat 17 is provided with an annular groove. The bottom end of the screw rod 15 is rotatably connected through the annular groove. The screw rod 15 passes through the screw hole 12 and the top end of the screw rod 15 is fixedly connected to the handle 16.

[0015] In this embodiment, both the first support rod 5 and the second support rod 8 are telescopic rod structures composed of a mother rod, a daughter rod, and length-fixing bolts. One end of the mother rod is telescopically connected to the daughter rod, and the side wall of the mother rod is provided with fixing bolts to fix the telescopic length of the daughter rod. By adjusting the length and angle of the first support rod 5 and the second support rod 8, the pressure plate 10 can contact and press against other fixed objects on the side of the bearing seat, thereby further securing the position of the bearing seat.

[0016] In this embodiment, the mother rod of the first support rod 5 is hinged to the top surface of the base 2 through the first hinge support 6, the son rod of the first support rod 5 is hinged to the son rod of the second support rod 8 through the second hinge support 7, and the mother rod of the second support rod 8 is hinged to the pressure plate 10 through the third hinge support 9.

[0017] When installing the anti-slip bearing seat, first use the positioning bolts 4 to fix the base 2 to the fixed object below. Then adjust the angle of the support rod and hinge support in the clamping mechanism so that the two pressure plates 10 are clamped onto the fixed objects on both sides, achieving a further fixing effect. Depending on the installation environment, you can choose whether to unscrew the suction cup downwards for suction fixation. Turn the handle clockwise to move the screw 15 downwards, causing the suction cup 14 to extend from the groove 13 and contact the plane of the fixed object below the base 2 for vacuum suction.

[0018] It should be noted that in the multiple anti-slip structure, the combination of positioning bolt 4 and suction cup 14 is a complementary design based on the needs of different scenarios.

[0019] Firstly, although positioning bolts have high static strength, they may loosen due to prolonged vibration under high-frequency vibration and impact load conditions. In such cases, a suction cup can counteract some of the lateral shear force through continuous suction, slowing down the loosening of the positioning bolt. For example, in motors and pumps, where bearing housings are subject to periodic vibration, the suction cup can provide cushioning protection when the preload of the positioning bolt decreases, preventing instantaneous slippage.

[0020] Secondly, when the mounting surface is smooth metal, glass, or composite material, the positioning bolts require pre-drilling, which may compromise the integrity of the surface. The suction cup structure allows for damage-free fixing, and with a small number of positioning bolts, it meets strength requirements while protecting the mounting surface. Furthermore, in temporary installation and debugging scenarios, the suction cup can quickly position the bearing housing, avoiding thread wear caused by repeated removal of the positioning bolts.

[0021] Then, the stress from the fixing bolts concentrates around the bolt holes, potentially causing localized deformation at the bottom of the bearing housing. The suction cup, through surface contact, distributes pressure evenly across the suction area, forming a point-to-surface force system with the bolt, reducing localized stress peaks. For example, on cast iron bearing housings, the suction cup can reduce the risk of cracking caused by excessive preload on the fixing bolts.

[0022] Finally, redundancy design is a crucial principle in industrial equipment safety standards. When positioning bolts fail due to accidental breakage or loosening, suction cups can serve as an emergency anti-slip measure, preventing sudden displacement of the bearing housing and subsequent cascading failures. This double protection is particularly important in high-risk scenarios such as lifting machinery and conveying equipment, buying valuable time for troubleshooting.

[0023] In conclusion, the suction cup structure does not replace the positioning bolt, but rather forms a more comprehensive anti-slip system through functional complementarity, taking into account strength, adaptability and safety, and its advantages are more obvious, especially in complex working conditions.

[0024] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
