Description

Technical Field

[0001] The utility model relates to the field of bearing lubrication equipment, in particular to a bearing lubrication device. Background Art

[0002] The motor supports the rotation of the rotor through the bearings at both ends. The grease effect of the bearings is to ensure the life of the bearings. Bearing grease lubrication refers to filling the grease into the gap between the inner and outer rings of the bearing. There are two filling methods: manual repeated extrusion and equipment vacuum filling.

[0003] In the prior art, during the vacuuming and filling process of the equipment, the bearing is first pressed by the upper and lower silicone rubber pads to make the gap between the inner ring and the outer ring of the bearing in a sealed state. After the gap between the inner and outer rings is vacuumed by the vacuum pump, the chamber between the inner ring and the outer ring of the bearing is at a certain negative pressure. Then, the oil filling pump is turned on to fill grease into the chamber between the inner ring and the outer ring of the bearing. After completion, the upper and lower silicone rubber pads can be detached.

[0004] However, due to the negative pressure in the chambers of the inner ring and the outer ring during the filling process, there will be a certain adsorption force when the upper and lower rubber pads are separated from the bearing, so that the bearing may always adhere to the upper silicone rubber pad, causing the bearing to be at risk of falling off during the separation of the bearing lubrication device from the bearing.

[0005] Therefore, how to improve the reliability of the bearing lubrication device and reduce the risk of the bearing falling is a technical problem that technical personnel in this field currently need to solve. Utility Model Content

[0027] The core of the utility model is to provide a bearing lubrication device, which can effectively improve the reliability of the bearing and the sealing gasket when they are separated, and avoid the risk of the bearing falling off.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of the exploded structure of a specific implementation of the bearing lubrication device provided by the utility model; Figure 2 for Figure 1 AA section view of the bearing lubrication device shown.

[0030] In this embodiment, the bearing lubrication device comprises:

[0031] A grease injection head 1, the grease injection head 1 is provided with a vacuum port 12 and a grease injection port 11;

[0032] The base 2 is used to support the grease injection head 1, and a space for fixing the bearing 6 is provided between the grease injection head 1 and the base 2;

[0033] Sealing gaskets are located at both axial ends of the bearing 6 to seal the cavity between the inner ring 61 and the outer ring 62 of the bearing 6, and the vacuum port 12 and the grease injection port 11 are both connected to the cavity;

[0034] A separation component 5, one end of which is mounted on the grease injection head 1, and the other end of which can abut against the end surface of the bearing 6, and when the grease injection head 1 is away from the base 2, the end of the separation component 5 can push the bearing 6 to separate the bearing 6 and the sealing gasket.

[0035] Specifically, the vacuum port 12 and the grease injection port 11 on the grease injection head 1 are separately arranged, and the vacuum port 12 and the grease injection port 11 are both connected to the cavity. The number of grease injection ports can be designed according to actual needs to achieve uniform grease injection during the grease injection process, and the vacuum port 12 only needs to be set at one place; when grease injection is required, the grease injection port 11 is first closed, and then the air in the cavity is extracted through the vacuum port 12 to form a negative pressure in the cavity, and then the vacuum port 12 is closed, and grease is injected into the cavity through the grease injection port 11, so that the friction between the inner ring 61 and the outer ring 62 of the bearing 6 is reduced, thereby improving the service life and performance of the bearing 6; when the grease injection work is completed, the grease injection head 1 is lifted and kept away from the base 2. At this time, one end of the separation component 5 extends out and pushes the bearing 6 to separate the bearing 6 and the sealing gasket located on the grease injection head 1.

[0036] The bearing lubrication device provided by the utility model pushes the bearing 6 through the separation component 5 when the grease injection head 1 is separated from the base 2, so that the sealing gasket and the bearing 6 are smoothly separated, thereby avoiding adhesion between the bearing 6 and the sealing gasket, and further avoiding the risk of the bearing 6 falling off.

[0037] In some embodiments, the sealing gasket includes a first sealing gasket 3 and a second sealing gasket 4, the first sealing gasket 3 is installed on the grease injection head 1, and the first sealing gasket 3 and the second sealing gasket 4 are respectively located at the axial ends of the bearing 6; and the first sealing gasket 3 is provided with connecting holes at positions corresponding to the grease injection port 11 and the vacuum port 12, and a through hole is provided at a position corresponding to the separation component 5. In other words, the first sealing gasket 3 is provided with a plurality of connecting holes for the grease injection port 11 or the vacuum port 12 to communicate with the cavity; and is also provided with a plurality of through holes for the separation component 5 to penetrate. The first sealing gasket 3 and the second sealing gasket 4 are preferably rubber gaskets.

[0038] In some embodiments, the through hole is located at a position on the first sealing gasket 3 corresponding to the outer ring 62 of the bearing 6, and the through hole is isolated from the cavity. Specifically, this can be achieved by setting the diameter of the through hole to be smaller than the width of the outer ring 62. The through hole is isolated from the cavity to avoid air leakage at the position of the through hole when the cavity is evacuated, so as to ensure the sealing effect of the first sealing gasket 3.

[0039] In some embodiments, the first sealing gasket 3 is fixed to one end of the grease injection head 1 close to the base 2, and a limiting boss is provided in the middle of the end of the grease injection head 1 close to the base 2, and the diameter of the limiting boss corresponds to the aperture of the inner ring 61 of the bearing 6, and the first sealing gasket 3 surrounds the periphery of the limiting boss. Specifically, the first sealing gasket 3 can be pasted on the end face of the grease injection head 1 close to the base 2 to facilitate the fixation of the first sealing gasket 3; the diameter of the limiting boss corresponds to the aperture of the inner ring 61 of the bearing 6, in order to achieve the positioning of the bearing 6 and facilitate the installation of the bearing 6.

[0040] In some embodiments, there are multiple separation components 5, which are evenly distributed along the circumference of the grease injection head 1. Specifically, by providing multiple separation components 5, when the grease injection head 1 is separated from the base 2, the first sealing gasket 3 and the bearing 6 can be quickly separated, so that the bearing 6 is prevented from being adsorbed on the first sealing gasket 3, thereby avoiding the risk of the bearing 6 falling after being sucked up, and reducing the damage to the bearing 6.

[0041] In some embodiments, one end of the separation component 5 corresponds to the outer ring 62 of the bearing 6 or corresponds to the inner ring 61 of the bearing 6. Specifically, by making one end of the separation component 5 correspond to the outer ring 62 or the inner ring 61 of the bearing 6, it is convenient to push the bearing 6. Since the width of the outer ring 62 of the bearing 6 is relatively large, it is preferred to abut one end of the separation component 5 against the outer ring 62 of the bearing 6.

[0042] In some embodiments, the separation component 5 is cylindrical, and the separation component 5 corresponds to the inner ring 61 of the bearing 6, and can abut against the end surface of the inner ring 61. Specifically, the separation component 5 can also be cylindrical and installed on the injection molding head. The abutment between the cylindrical separation component 5 and the inner ring 61 or the outer ring 62 of the bearing 6 facilitates the separation of the first sealing gasket 3 and the bearing 6. This method has better separation efficiency and more stable force. The action of the separation component 5 can be achieved by the elastic component 52 or by other electrical components.

[0043] In some embodiments, the grease injection head 1 is further provided with an installation groove, in which the separation component 5 is arranged. Specifically, the installation groove can facilitate the arrangement of the separation component 5 without affecting the appearance of the grease injection head 1; the installation groove should be arranged at a position corresponding to the end surface of the bearing 6.

[0044] In some embodiments, the separation component 5 includes an elastic component 52 and a movable pin 51, one end of the movable pin 51 abuts against the elastic component 52, and the other end can extend to the outside of the mounting groove and abut against the end surface of the bearing 6. The elastic component 52 is preferably a spring. The movable pin 51 is preferably a metal movable pin 51, which has high strength and good separation effect.

[0045] In a specific embodiment, several elastic components 52 and movable pins 51 are arranged around the first sealing gasket 3, and the first sealing gasket 3 is separated from the bearing 6 by the elastic force of the structure, so as to ensure that the bearing 6 will not adhere to the first sealing gasket 3 after separation, thereby realizing the automatic completion of the greasing process of the bearing 6. In addition, the separation component 5 includes a movable pin 51 and an elastic component 52, and the movable pin 51 and the elastic component 52 form an elastic top-opening structure, which is evenly distributed on the outer ring 62 of the bearing 6, and the diameter of the movable pin 51 is smaller than the width of the outer ring 62 of the bearing 6, so as to ensure the performance of the first sealing gasket 3.

[0046] Furthermore, during the vacuuming and filling process of the equipment, the bearing 6 is first compressed by the first sealing gasket 3 and the second sealing gasket 4; the cavity between the inner ring 61 and the outer ring 62 of the bearing 6 is in a sealed state, and the cavity between the inner ring 61 and the outer ring 62 is vacuumed by a vacuum pump; after the cavity between the inner ring 61 and the outer ring 62 of the bearing 6 is at a certain negative pressure, the oil filling pump is turned on to fill grease into the cavity of the bearing 6; after the grease filling is completed, the first sealing gasket 3 and the second sealing gasket 4 are detached, and the circumferentially arranged elastic component 52 and the movable pin 51 of the first sealing gasket 3 separate the first sealing gasket 3 from the bearing 6 through the elastic force of the structure.

[0047] In some embodiments, the separation component 5 is a gas cylinder, an oil cylinder or an electric cylinder. Specifically, by replacing the elastic component 52 and the movable pin 51 with a gas cylinder, an oil cylinder or an electric cylinder, the separation efficiency and reliability of the first sealing gasket 3 and the bearing 6 can be improved, and the elasticity reduction caused by the long use of the elastic component 52 can be avoided.

[0048] Of course, the bearing lubrication device can be used not only for separating the bearing 6 from the sealing gasket, but also for separating the bearing 6 from the mold.

[0049] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0050] The above is a detailed introduction to the bearing lubrication device provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
