Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing housing technology, and more specifically, to a bearing housing with replaceable bearings. Background Technology
[0002] In the field of mechanical transmission, bearing housings are key components that support bearings and fix their positions. They are widely used in various mechanical equipment. At present, most bearing housings adopt a fixed structure that integrates the bearing and the housing or cannot be easily disassembled. When the bearing wears, fatigues or is damaged due to long-term operation, it is often necessary to replace the entire bearing housing. This not only causes a lot of material waste, but also significantly increases maintenance costs and downtime.
[0003] Some bearing housings are designed with a separable structure, but the disassembly process is complex, generally requiring multiple fastening screws for fixation. Tightening and loosening these screws is time-consuming, and requires specialized tools and extremely high assembly precision. Inaccurate alignment can prevent the screws from being properly tightened, and positional deviations can damage the bearing housing itself, further reducing equipment reliability. Therefore, we propose a replaceable bearing housing. Utility Model Content
[0004] The purpose of this invention is to provide a bearing housing with replaceable bearings to solve the defects mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A replaceable bearing housing includes a bearing base, a bearing top seat above the bearing base, bearing assembly chambers on the adjacent sides of both the bearing base and the bearing top seat, and a bearing embedded in each bearing assembly chamber. Two symmetrical protrusions are fixedly installed on the left and right sides of the bearing base, and vertically arranged guide rods are fixedly installed on the top surfaces of the protrusions. A top plate is fixedly installed at the top of multiple guide rods. Guide blocks are fixedly installed on the sides of the bearing top seat, and the guide blocks are fitted onto the guide rods and slidably connected to them. A screw is threaded onto the top plate, and a protrusion is fixedly installed at the bottom end of the screw. A bushing is rotatably connected to the protrusion, and an arc-shaped clamping sleeve is fixedly installed at the bottom end of the bushing. The arc-shaped clamping sleeve is located above the bearing top seat and presses the bearing top seat against the top surface of the bearing base.
[0007] Preferably, fixed supports are fixedly installed on both the left and right sides of the bearing base, and the fixed supports are fixedly installed on the external frame.
[0008] Preferably, the distance between the two guide rods on each side is greater than the width of the bearing, and the size of the bearing is adapted to the size of the bearing assembly chamber.
[0009] Preferably, a rubber anti-loosening pad is fitted on the top surface of the bearing top seat, and the arc-shaped clamping sleeve is pressed onto the rubber anti-loosening pad.
[0010] Preferably, side guide plates are fixedly installed at both ends of the arc-shaped clamping sleeve, and the side guide plates are sleeved on the guide rod and slidably connected to the guide rod.
[0011] Preferably, a knob is fixedly installed at the top of the screw, and the size of the rubber anti-loosening pad is adapted to the size of the bearing top seat.
[0012] Preferably, the size of the arc-shaped clamping sleeve is adapted to the size of the rubber anti-loosening pad, and the thickness of the rubber anti-loosening pad is between 0.15cm and 0.3cm.
[0013] Preferably, side reinforcing plates are fixedly installed on both the left and right sides of the top surface of the arc-shaped clamping sleeve, and two symmetrical inclined support rods are fixedly installed between the side reinforcing plates and the bushing.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model achieves convenient opening and closing of the bearing seat by setting a split structure consisting of a bearing base and a bearing top seat, combined with the sliding connection design of the guide rod and the guide block. When replacing the bearing, simply rotate the screw to raise the arc-shaped clamping sleeve to easily disassemble the bearing top seat without replacing the whole bearing, which greatly reduces maintenance costs and material waste.
[0016] 2. This utility model relies on the combination of an arc-shaped clamping sleeve, a rubber anti-loosening pad, and a side guide plate. When the screw is tightened, it can form a uniform and stable clamping force on the bearing top seat. The rubber anti-loosening pad can not only enhance the buffering effect but also prevent loosening caused by vibration. The side guide plate further constrains the movement trajectory of the clamping sleeve, ensuring the stability and coaxiality of the bearing after assembly.
[0017] 3. This utility model utilizes the rotating connection between the protruding column and the bushing, as well as the reinforced structure of the side reinforcement plate and the inclined support rod, to ensure that the arc-shaped clamping sleeve maintains a balanced force during the application of force.

[0027] 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.
[0028] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0029] Please see Figures 1-5This utility model provides a technical solution: a bearing housing with replaceable bearings, including a bearing base 1, a bearing top seat 15 disposed on the top of the bearing base 1, and bearing assembly chambers 10 disposed on the sides of the bearing base 1 and the bearing top seat 15 that are close to each other. A bearing 16 is embedded in the bearing assembly chamber 10. By setting a split structure between the bearing base 1 and the bearing top seat 15, the bearing assembly chambers 10 on the sides of the two can jointly embed the bearing 16, so that when the bearing 16 is replaced, only the bearing top seat 15 needs to be removed to remove the bearing 16, avoiding the disadvantages of replacing the entire bearing housing in the traditional one-piece bearing housing, and greatly reducing maintenance costs and material waste.
[0030] Specifically, two symmetrical protrusions 12 are fixedly installed on both the left and right sides of the bearing base 1. A vertically arranged guide rod 13 is fixedly installed on the top surface of the protrusion 12. A top plate 14 is fixedly installed on the top of the multiple guide rods 13. A guide block 151 is fixedly installed on the side of the bearing top seat 15. The guide block 151 is sleeved on the guide rod 13 and slidably connected to the guide rod 13. A screw 33 is threadedly connected to the top plate 14, so that the bearing top seat 15 moves along a fixed trajectory when it opens and closes, which not only ensures the assembly accuracy, but also prevents misalignment and damage to the bearing 16. At the same time, the top plate 14 at the top of the guide rod 13 provides a fixed support point for the screw 33, enhancing the overall structural stability.
[0031] Specifically, a protrusion 32 is fixedly installed at the bottom end of the screw 33, and a bushing 31 is rotatably connected to the protrusion 32. An arc-shaped clamping sleeve 3 is fixedly installed at the bottom end of the bushing 31. The arc-shaped clamping sleeve 3 is located above the bearing top seat 15. The arc-shaped clamping sleeve 3 presses the bearing top seat 15 against the top surface of the bearing base 1. When the screw 33 is rotated, the bushing 31 can rotate freely, which prevents the arc-shaped clamping sleeve 3 from shifting due to friction, ensuring uniform clamping of the bearing top seat 15 and improving assembly reliability.
[0032] In this embodiment, fixed supports 11 are fixedly installed on both the left and right sides of the bearing base 1. The fixed supports 11 are fixedly installed on the external frame by fastening screws, which facilitates the fixing of the fixed supports 11 and achieves the effect of fixing the bearing base 1.
[0033] Specifically, the distance between the two guide rods 13 on each side is greater than the width of the bearing 16, and the size of the bearing 16 is adapted to the size of the bearing assembly chamber 10, so that the bearing 16 can be taken out normally for replacement after the bearing top seat 15 is opened.
[0034] Furthermore, a rubber anti-loosening pad 2 is fitted on the top surface of the bearing top seat 15, and an arc-shaped clamping sleeve 3 is pressed on the rubber anti-loosening pad 2. The thickness of the rubber anti-loosening pad 2 is between 0.15cm and 0.3cm. Under the action of the arc-shaped clamping sleeve 3, the rubber anti-loosening pad 2 undergoes elastic deformation, fills the gap and buffers vibration, and prevents the bearing seat from loosening.
[0035] In addition, side guide plates 30 are fixedly installed at both ends of the arc-shaped clamping sleeve 3. The side guide plates 30 are sleeved on the guide rod 13 and slidably connected to the guide rod 13, further constraining the downward pressing path of the arc-shaped clamping sleeve 3, ensuring that the clamping force acts perpendicularly on the bearing top seat 15, and enhancing the overall anti-loosening effect.
[0036] It is worth noting that a knob 34 is fixedly installed at the top of the screw 33, which facilitates quick manual tightening or loosening, making operation convenient and efficient. Side reinforcement plates 35 are fixedly installed on both the left and right sides of the top surface of the arc-shaped clamping sleeve 3. Two symmetrical inclined support rods 36 are fixedly installed between the side reinforcement plates 35 and the bushing 31. The side reinforcement plates 35 and the inclined support rods 36 of the arc-shaped clamping sleeve 3 form a triangular support system, which disperses stress when force is applied, avoids deformation of the arc-shaped clamping sleeve 3, and ensures long-term stability and clamping reliability.
[0037] It is worth noting that the size of the rubber anti-loosening pad 2 is adapted to the size of the bearing top seat 15, and the size of the arc-shaped clamping sleeve 3 is adapted to the size of the rubber anti-loosening pad 2, which is used to stabilize the assembly operation.
[0038] When using the replaceable bearing housing of this utility model, the bearing base 1 is fixed to the external frame by fastening screws through the fixed support 11 to ensure stability; when replacing the bearing 16, the knob 34 at the top of the rotating screw 33 lifts the arc-shaped clamping sleeve 3 upward, and its side guide plate 30 rises synchronously along the guide rod 13 to release the pressure on the bearing top seat 15.
[0039] Subsequently, the bearing top seat 15 is slid upward along the guide rod 13. Its guide block 151 cooperates with the guide rod 13 to ensure accurate movement trajectory and avoid collision with the bearing 16. After the bearing top seat 15 is fully opened, because the spacing of the guide rods 13 is greater than the width of the bearing 16, the old bearing 16 can be directly removed from the bearing assembly chamber 10 and a new bearing can be installed.
[0040] During reset, the bearing top seat 15 is slid down along the guide rod 13 until it fits against the bearing base 1. At this time, the bearing 16 is embedded in the bearing assembly chamber 10 of the two. Rotating the knob 34 causes the screw 33 to drive the arc-shaped clamping sleeve 3 to press down, ensuring that the arc-shaped clamping sleeve 3 applies vertical pressure to the rubber anti-loosening pad 2. The elastically deformed rubber anti-loosening pad 2 fills the gap and buffers vibration. Combined with the triangular support structure of the side reinforcement plate 35 and the inclined support rod 36, the bearing seat is stably assembled and can operate reliably for a long time.
[0041] 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 preferred examples and are not intended to limit the utility model.
