Description

Technical Field

[0001] The utility model relates to the technical field of bearing seats, in particular to a bearing seat with a surfacing structure. Background Art

[0002] A bearing seat is a support seat that can be used to carry and support bearings. Bearings are used inside large mechanical devices and are widely used in all walks of life. They can be used for load-bearing support or selection inside the device, which can effectively reduce the friction loss of the internal structure of the equipment. Bearings are generally used in conjunction with bearing seats, so the performance of the bearing seat directly affects the effectiveness of the bearing.

[0003] The bearings are constantly rotating during the working process. As the bearings rotate, they are prone to wear. Therefore, it is necessary to continuously inject engine oil to improve lubrication. Once the bearings are severely worn, it will affect the mechanical transmission efficiency, resulting in reduced transmission efficiency. In severe cases, it will cause damage to the drive shaft.

[0004] The oil filling holes in the existing bearings are mostly open, so after long-term use, the oil filling holes will be filled with dust, which will cause blockage inside the oil filling holes, and eventually the problem of not being able to inject oil into the bearing through the oil filling holes will occur. Therefore, it is necessary to make corresponding improvements to the oil filling holes set inside the existing bearings.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0009] Preferably, the oil filling seal assembly comprises a round block sleeved on the oil filling hole, a plurality of evenly distributed sealing sheets are provided in the oil filling hole, and a movable block extending into the round block is provided on one side of the sealing sheet.

[0010] Preferably, the movable block is sleeved with a matching sliding sleeve, and a rotating ring connected to a plurality of the sliding sleeves is provided inside the circular block, and the rotating ring extends outside the circular block.

[0011] Preferably, a slide groove is provided at the bottom end of the circular block and below the movable block, and a slide rod connected to the movable block is provided in the slide groove.

[0013] Preferably, the fixing ring is provided with a guide hole for the movable block to move, and the sealing sheets are in three groups and are closed to each other.

[0014] Preferably, a mounting seat is symmetrically fixedly connected to the side wall of the fixing seat close to the bottom end, and a reinforcing block with a right-angled triangle structure is provided at the top of the mounting seat.

[0015] The beneficial effects of the utility model are as follows: a welded cladding reinforcement block is welded between the fixed seat and the mounting seat to achieve structural reinforcement; the cladding reinforcement block is a triangular structure with good structural stability, thereby effectively ensuring the stability of the overall structure of the bearing seat; through the coordinated arrangement of the oil filling seal assembly and the oil filling hole, the problem of the oil filling holes in the existing bearings being mostly open-type arrangements can be effectively solved, so that after long-term use, the oil filling holes will be filled with dust, resulting in blockage inside the oil filling holes, and ultimately resulting in the problem of being unable to perform oil filling operations into the bearing through the oil filling holes.

[0030] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0031] In actual application, when it is necessary to inject oil into the interior of the bearing seat to lubricate the bearing, the rotating ring 12 is rotated to drive the sleeve 11 to perform a circular motion in the round block 8. The round block 8 drives the movable block 10 to move synchronously during the circular motion, so that the slide rod 14 on the movable block 10 slides in the slide groove 13. The slide rod 14 drives the movable block 10 to move left and right in the sleeve 11 as the position of the slide groove 13 changes, so that the movable block 10 drives the sealing sheet 9 to separate from each other, so that the oil filling hole 7 is in an open state, and then lubricating oil can be added to the inside through the oil filling hole. After completion, the rotating ring 12 is loosened, and the rotating ring 12 is automatically reset under the action of the torsion spring, so that the sealing sheets 9 are closed to each other, the oil filling hole can be automatically sealed, and dust can be effectively prevented from entering the body.

[0032] To sum up, with the help of the above-mentioned technical scheme of the utility model, the welded surfacing reinforcement block is welded between the fixed seat 1 and the mounting seat 16 to achieve structural reinforcement. The welded surfacing reinforcement block is a triangular structure with good structural stability, thereby effectively ensuring the stability of the overall structure of the bearing seat; through the coordinated setting of the oil filling seal assembly and the oil filling hole 7, it can effectively solve the problem that most of the oil filling holes in the existing bearings are open-type settings, so that after long-term use, the oil filling holes will be filled with dust, resulting in blockage inside the oil filling holes, and ultimately the problem of not being able to fill oil into the bearing through the oil filling hole.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
