The utility model provides an insert bearing assembly system, includes roller conveyor 4 and assembly quality 7, and the system still includes hybrid tube 3 and lubricating grease conveyor, and the one end of hybrid tube 3 is linked together with lubricating grease conveyor, and the middle part of hybrid tube 3 is linked together with roller conveyor 4, and the other end of hybrid tube 3 is linked together with assembly quality 7.

When the grease feeding device is used, the grease 11 is fed into the mixing tube 3 by the grease feeding device, the rollers 10 are fed into the mixing tube 3 by the roller feeding device 4, the grease 11 and the rollers 10 are mixed in the mixing tube 3, the rollers 10 are uniformly distributed along the axial direction of the mixing tube 3 after mixing, the grease 11 is filled between every two adjacent rollers 10, because the grease 11 is thick, the subsequent grease 11 can push the mixture of the rollers 10 and the grease 11 into the assembling device 7, the rollers 10 and the grease 11 synchronously enter the roller path of the outer ring during the assembling of the outer spherical bearing, and the grease does not need to be refilled after the retainer is installed, so that the assembling process is simplified, the assembling cost is reduced, in addition, the grease 11 can be prevented from being left on the outer wall of the outer spherical bearing, and the packing and transportation are convenient.

It should be noted that, the outer spherical bearing is a modification of the deep groove ball bearing, and the overall structure thereof is not different, so that the roller conveying device 4 and the assembling device 7 in this embodiment may both adopt devices adopted for assembling the deep groove ball bearing in the prior art, which are well-established prior art, and are not described herein again.

In this embodiment, the grease feeding device includes a grease storage tank 1, the grease storage tank 1 is communicated with an output pump 2, and an output end of the output pump 2 is communicated with a mixing pipe 3. The delivery pump 2 needs to be a pump capable of adjusting the delivery speed so that the filling amount of the grease 11 between the adjacent two rollers 10 can be controlled.

In this embodiment, the roller conveying device 4 is communicated with a roller conveying pipe 5, a gap is formed in the middle of the mixing pipe 3, the roller conveying pipe 5 is inserted into the gap, an expanding portion is formed on the inner wall of one end, communicated with the mixing pipe 3, of the roller conveying pipe 5, a flexible blocking piece 8 is fixedly arranged in the expanding portion, and a through hole 9 is formed in the middle of the flexible blocking piece 8. Because the roller conveying pipe 5 and the mixing pipe 3 are communicated, and the mixing pipe 3 contains a large amount of grease 11, although the grease 11 will not flow into the roller conveying pipe 5 to cause great negative effects, but will cause the grease 11 to adhere to the surface when the rollers 10 are output from the roller conveying pipe 5, and cause the amount of the grease 11 filled between two adjacent rollers 10 to be not controlled well, the present embodiment adopts a mode that a soft baffle 8 is arranged at the communication position of the roller conveying pipe 5 and the mixing pipe 3, the through hole 9 is used as a passage of the rollers 10 to ensure that the rollers 10 can smoothly enter the mixing pipe 3, and the soft baffle 8 can deform to be attached to the surface of the rollers 10 when the rollers 10 pass through the through hole 9, so as to prevent the grease 11 from entering the roller conveying pipe 5 from the hole wall between the rollers 10 and the through hole 9, and when one roller 10 enters the mixing pipe 3, a part of the subsequent rollers 10 can enter the through hole 9 after being restored to seal the same, and further prevent the grease 11 from entering the rollers 5.

In this embodiment, the inner diameter of the through-hole 9 is smaller than the diameter of the roller 10. The smaller internal diameter of the through bore 9 ensures that a portion of the roller 10 can extend into the through bore 9 to close the through bore 9 and prevent grease 11 from entering the roller duct 5.

In this embodiment, the roller feed pipe 5 is located below the mixing pipe 3. Because the gravity borne by the roller 10 is greater than the gravity borne by the grease 11 under the same volume, the roller conveying pipe 5 is arranged below the mixing pipe 3, so that the roller 10 in the roller conveying pipe 5 can be prevented from extruding the soft baffle 8 under the action of gravity, and the interference on the flow of the grease 11 in the mixing pipe 3 can be avoided.

In this embodiment, mixing tube 3 communicates with fitting device 7 via flexible conduit 6. The flexible conduit 6 can control the flow direction of the mixture of the roller 10 and the grease 11, so that the flow direction is not limited by space, and the layout and the assembly of field equipment are more convenient.

In this embodiment, considering that a mixture of the roller 10 and the grease 11 is easy to remain on the working platform, and a conventional manner of transporting a bearing by a conveyor belt is easy to cause a large amount of grease to adhere to the conveyor belt, the conveyor belt in the assembling device 7 is improved in this embodiment, a plurality of outer ring containers are fixedly arranged on the conveyor belt, each outer ring container includes a tray 17 and a bottom plate 13 detachably arranged on the tray 17, a through hole is formed in the middle of the bottom plate 13, a sheath 12 and a limit ring 14 are fixedly arranged on the bottom plate 13, the sheath 12 is located on the periphery side of the limit ring 14, a gap for accommodating the outer ring is left between the sheath 12 and the limit ring 14, the inner diameter of the limit ring 14 is equal to the aperture of the through hole, a plurality of radially extending support rods 16 are fixedly connected to the inner side of the limit ring 14, and all the support rods 16 are commonly connected to a connection plate 15 coaxially arranged with the limit ring 14. During assembly, the outer ring is placed in the gap and the inner ring is placed on the support rod 16, and when the mixture of the roller 10 and the grease 11 is fed between the inner and outer rings, some of the grease 11 may fall down through the gap and through-holes between the support rod 16 into the tray 17, thereby avoiding contamination of the conveyor belt and the worktop, and after a certain period of use, the bottom plate 13 and the tray 17 may be separated to clean the grease 11 in the tray 17. In fact, because the grease 11 has poor fluidity, there is substantially little grease 11 that falls down, and therefore the tray 17 can be used for a long time after a single cleaning, without requiring frequent cleaning of the tray 17.

The assembling method of the assembling system comprises the following steps S1 to S4:

s1, the grease conveying device conveys grease 11 into the mixing pipe 3.

And S2, after the part of the mixing pipe 3 corresponding to the roller conveying device 4 is filled with the grease 11, the roller conveying device 4 conveys the roller 10 into the mixing pipe 3.

S3, the grease feeding device continuously feeds the grease 11 into the mixing tube 3, and the mixture of the roller 10 and the grease 11 in the mixing tube 3 is fed into the flexible guide tube 6 by the grease 11.

S4, the mixture of the roller 10 and the grease 11 in the flexible conduit 6 enters the fitting device 7 under the thrust of the subsequent grease 11 in the mixing tube 3.

In the present embodiment, the specific method of step S1 includes steps S1.1 to S1.5.

With the above method, it is possible to directly fill the grease 11 at the time of filling the roller 10, thereby quickly assembling the spherical outer bearing.

S1.1, determining the diameter of the rollers 10 and the number of rollers 10 in each spherical outer bearing.

S1.2, determining the distance between two adjacent rollers 10 according to the diameters of the rollers 10 and the number of the rollers 10.

S1.3, determining the amount of the lubricating grease between two adjacent rollers 10 according to the distance between two adjacent rollers 10.

S1.4, determining the conveying speed of the grease 11 according to the amount of the grease between two adjacent rollers 10 and the conveying speed of the roller conveying device 4.

S1.5, the grease conveying device conveys the grease 11 to the mixing pipe 3 according to the conveying speed of the grease 11.

Because the sizes of different spherical bearings are different, the required amount of the lubricating grease 11 is also different, so the method firstly controls the conveying speed of the lubricating grease 11 according to the actual parameters of the spherical bearings, and indirectly controls the using amount of the lubricating grease 11, so as to ensure that the filled lubricating grease 11 can meet the use requirements of the spherical bearings.

In the present embodiment, in step S2, the roller 10 passes through the through hole 9 when entering the mixing tube 3 from the roller conveying tube 5, and the soft flap 8 is pressed to closely adhere the soft flap 8 to the roller 10.

In this embodiment, in step S2, after one roller 10 enters the mixing tube 3, a part of the subsequent roller 10 protrudes into the through hole 9 to close the through hole 9.
