Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to floating base bearings. Background Technology

[0002] Floating base bearings are widely used in the operation of mechanical equipment. They can adapt to displacement and vibration during equipment operation to a certain extent, ensuring stable operation of the equipment.

[0003] However, the existing technology has the following drawbacks:

[0004] When the equipment generates significant vibrations during operation, the bearings cannot effectively buffer the impact, which can easily lead to loosening or even damage of internal parts. Existing bearings have poor sealing performance, allowing external dust and impurities to easily enter the bearings, accelerating wear and reducing their service life. Furthermore, they are difficult to position precisely during installation, which can easily lead to installation deviations, affecting the bearings' performance and the operational stability of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a floating base bearing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a floating base bearing, comprising a base, a bearing housing, and a bearing body. The base has fixed cylinders on both sides, with internal threads evenly distributed on the inner side of each fixed cylinder. A through hole is formed in the center of the base. The bearing housing is inserted into the through hole, and its outer wall is fixedly connected to the inner wall of the through hole. A mounting groove is formed at the top of the bearing housing, and the bearing body is fitted into the mounting groove. Several shock-absorbing rubber pillars are evenly distributed along the circumferential direction on the bottom inner wall of the mounting groove. The tops of the shock-absorbing rubber pillars are tightly abutted against the bottom of the bearing body. A sealing sheet is provided on the top of the bearing housing.

[0007] By adopting the above technical solution, the shock-absorbing rubber column plays a role in buffering and shock absorption protection, and the sealing sheet enhances the sealing performance, preventing dust and impurities from entering the bearing and extending the bearing's service life.

[0008] The base is a rectangular frame with rounded corners at both ends. The outer diameter of the fixing cylinder is the same as the inner diameter of the rounded corners at both ends of the base. The base is made of high-performance engineering plastic, and the bearing seat is an annular cylindrical shape.

[0009] Using the above technical solution, the high-performance engineering plastics are lubrication-free and maintenance-free, and the bearings are movable and corrosion-resistant.

[0010] Support rods are fixedly installed around the bottom inner side of the bearing housing. The cross-sectional shape of the support rods is fan-shaped, and their inner sides are tightly abutting against the inner side of the bearing body. A ring plate is fixedly installed on the top of the four support rods. The height of the bearing body is the same as the depth of the mounting groove.

[0011] Using the above technical solution, the support rod plays a supporting and fixing role for the ring plate, and the outer diameter of the ring plate is the same as the inner diameter of the bearing body.

[0012] The bearing body includes a retainer and an inner ring. Threaded holes are provided in the center of the inner ring's inner perimeter. Threaded through holes are provided in the center of the four support rods. The threaded through holes are stepped holes. Fastening bolts are sequentially threaded into the threaded through holes and the threaded holes.

[0013] In this technical solution, the screw thread of the fastening bolt is installed inside the threaded hole and the threaded through hole, and its head is located inside the large-diameter hole.

[0014] The retainer is sleeved on the outside of the inner ring, and several rolling elements are evenly distributed between them. Several positioning grooves are evenly distributed on the inner side of the inner ring, and the top of the positioning groove is located below the bottom of the ring plate.

[0015] By adopting the above technical solution, the positioning groove of the inner ring is engaged with the external structure of the shaft to prevent mutual rotation between the two and ensure stable movement.

[0016] The bearing housing has a second annular sealing groove at its top, and the ring plate has a first annular sealing groove at its top. The bottom of the sealing sheet has a first sealing ring and a second sealing ring arranged sequentially from the outside to the inside. The first sealing ring and the second sealing ring are respectively engaged and installed in the second annular sealing groove and the first annular sealing groove.

[0017] Using the above technical solution, the sealing sheet is installed on the top of the bearing housing by engaging with the first sealing ring and the second sealing ring.

[0018] The sealing sheet has a protrusion on one side and is made of silicone material. The thickness of the bearing body sidewall is the same as the thickness of the mounting groove, and a rubber pad is adhered to the inner wall of the mounting groove.

[0019] Using the above technical solution, the protrusions facilitate the removal of the sealing sheet, and the rubber pad provides cushioning and protection.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] By installing shock-absorbing rubber pillars between the bearing housing and the bearing, the bearing's buffering and shock absorption capabilities are greatly enhanced, effectively reducing the damage to the bearing caused by equipment vibration, extending the bearing's service life, reducing noise caused by vibration, and improving the stability and comfort of equipment operation. The sealing plate can effectively prevent external dust and impurities from entering the bearing, reducing the wear of internal bearing parts and improving the bearing's reliability and service life.
