Description

Technical Field

[0001] This utility model belongs to the technical field of lubricating oil filling devices, specifically a lubricating oil filling device for self-aligning roller bearings. Background Technology

[0002] Self-aligning roller bearings feature double-row rollers, with one common spherical raceway on the outer ring and two raceways on the inner ring that are angled relative to the bearing axis. This ingenious design gives them self-aligning properties, making them less susceptible to errors in the angle between the shaft and the bearing housing, or shaft bending. They are suitable for applications where angular errors are caused by installation errors or shaft deflection. During use, self-aligning roller bearings require lubrication, necessitating the use of a lubrication filling device.

[0003] Existing lubricating oil filling devices have relatively complete structures and functions, and can meet basic usage requirements, but the following problems still exist: In actual use, self-aligning roller bearings are double-row roller bearings, requiring lubrication from both sides. This necessitates lubrication on one side only, leading to repetitive operation steps. Furthermore, once the lubricant enters the bearing body, the inner ring needs to be manually rotated to ensure even lubrication. This manual rotation can be tiring, thus reducing overall efficiency. Utility Model Content

[0004] (a) Technical problems to be solved To overcome the aforementioned shortcomings of the prior art, this utility model provides a lubricating oil filling device for self-aligning roller bearings. This solves the problem that in actual use, self-aligning roller bearings are double-row roller bearings, requiring lubrication from both sides. This necessitates separate lubrication, meaning lubrication can only be applied to one side after the other, resulting in repetitive operation steps. Furthermore, after the lubricating oil enters the bearing body, the inner ring needs to be manually rotated to ensure even application, which is tiring and reduces overall efficiency.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a lubricating oil filling device for a self-aligning roller bearing, comprising a base and a self-aligning roller bearing body. The self-aligning roller bearing body has symmetrically arranged oil inlet grooves on both sides. A high-efficiency filling component is provided on the top of the base. An auxiliary filling component is provided between the top of the base and the self-aligning roller bearing body. The high-efficiency filling component includes an oil tank and a rectangular frame. The bottom of the rectangular frame and the oil tank are fixedly connected to the top of the base. A drive motor is installed on one side of the rectangular frame. A threaded rod is fixedly connected to the output end of the drive motor. The two ends of the threaded rod have opposite thread directions. Two threaded hole blocks are symmetrically threaded to the two ends of the threaded rod. The threaded hole blocks are slidably disposed on the inner wall of the rectangular frame. The auxiliary filling component includes a fixing block. A fixing groove is provided on the top of the fixing block. The self-aligning roller bearing body is engaged and adapted to the fixing groove.

[0006] As a further embodiment of this utility model: an auxiliary connecting rod is fixedly connected to the top of the screw hole block, an installation block is fixedly connected to one end of the auxiliary connecting rod, and an oil injection nozzle is fixedly installed on the inner wall of the installation block.

[0007] As a further embodiment of this utility model: a pump body is installed on one side of the oil tank, and the oil inlet end and oil outlet end of the pump body are respectively connected to an oil inlet pipe and an oil outlet pipe.

[0008] As a further embodiment of this utility model: the other end of the oil inlet pipe is connected to the oil tank, the other end of the oil outlet pipe is connected to an oil outlet branch pipe, and one end of the oil outlet branch pipe is connected to the oil injection nozzle.

[0009] As a further embodiment of this utility model: an L-shaped plate is fixedly connected to one side of the base, and a second motor is installed on one side of the L-shaped plate.

[0010] As a further embodiment of this utility model: a rotating rod is fixedly connected to the output end of the second motor, and a fixed rod is fixedly connected to one end of the rotating rod, the fixed rod being engaged with the inner ring of the self-aligning roller bearing body.

[0011] As a further embodiment of this utility model, a number of rubber protrusions are fixedly connected to the outer surface of the fixing rod.

[0012] (III) Beneficial Effects Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The lubricating oil filling device for self-aligning roller bearings, by setting up a high-efficiency filling component, can cooperate with two screw hole blocks to move towards or away from each other under the action of the threaded rod, so that two oil injection nozzles can be inserted into both sides of the self-aligning roller bearing body respectively, and lubricating oil can be injected into the interior of the self-aligning roller bearing body from the two oil injection nozzles at the same time.

[0013] 2. The lubricating oil filling device for self-aligning roller bearings is equipped with an oil outlet pipe and an oil inlet pipe. The oil outlet pipe can guide the lubricating oil to the oil outlet branch pipe, and then cooperate with two oil injection nozzles to add lubricating oil to the inside of the self-aligning roller bearing body.

[0014] 3. The lubricating oil filling device for self-aligning roller bearings, by setting an auxiliary filling component, allows the fixing block and fixing groove to lock and limit the self-aligning roller bearing body under the action of the auxiliary filling component. At the same time, under the action of the fixing rod, the inner ring of the self-aligning roller bearing body is locked, thereby assisting slow rotation and facilitating the even application of lubricating oil.

[0016] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0017] like Figure 1-4As shown, this utility model provides a technical solution: a lubricating oil filling device for self-aligning roller bearings, including a base 1 and a self-aligning roller bearing body 2. The self-aligning roller bearing body 2 has symmetrically arranged oil inlet grooves 3 on both sides for filling with lubricating oil. A high-efficiency filling component 4 is provided on the top of the base 1, and an auxiliary filling component 5 is provided between the top of the base 1 and the self-aligning roller bearing body 2. The high-efficiency filling component 4 includes an oil tank 41 and a rectangular frame 46. The bottom of the rectangular frame 46 and the oil tank 41 are fixedly connected to the top of the base 1. A drive motor 47 is installed on one side of the rectangular frame 46. The output end of 47 is fixedly connected to a threaded rod 48.

The threaded rod 48 can drive the threaded hole blocks 49 to move towards or away from each other. The threaded hole blocks 49 are slidably set on the inner wall of the rectangular frame 46. The auxiliary filling component 5 includes a fixing block 56. The top of the fixing block 56 is provided with a fixing groove 57. The self-aligning roller bearing body 2 is snapped into the fixing groove 57. The fixing groove 57 is a non-standard customized part and needs to be customized according to the size of the self-aligning roller bearing body 2. It can snap and fix the self-aligning roller bearing body 2.

[0018] Specifically, such as Figures 2-3 As shown, an auxiliary connecting rod 410 is fixedly connected to the top of the screw hole block 49. One end of the auxiliary connecting rod 410 is fixedly connected to a mounting block 411. An oil injection nozzle 412 is fixedly installed on the inner wall of the mounting block 411. The mounting block 411 provides a mounting platform for installing the oil injection nozzle 412. A pump body 42 is installed on one side of the oil tank 41. The oil inlet end and the oil outlet end of the pump body 42 are respectively connected to an oil inlet pipe 43 and an oil outlet pipe 44. The other end of the oil inlet pipe 43 is connected to the oil tank 41. The pump body 42 can guide the lubricating oil from the oil tank 41 to the oil outlet pipe 44. The other end of the oil outlet pipe 44 is connected to an oil outlet branch pipe 45. One end of the oil outlet branch pipe 45 is connected to the oil injection nozzle 412.
