Description

Technical Field

[0001] This utility model relates to the field of bearing housing maintenance technology, specifically a device for accelerating the application of grease to bearing housings. Background Technology

[0002] The bearing inside the bearing housing needs to be replenished with grease, which can form an oil film to reduce direct contact and friction wear of the bearing. At the same time, it plays a role in heat dissipation, sealing, rust prevention and shock absorption, thereby effectively extending the service life of the bearing and reducing the equipment failure rate.

[0003] In related technologies, various types of rollers are generally equipped with two bearing housings. When replacing or installing bearing housings on rollers in production line equipment, it is necessary to apply oil to the bearings. Currently, the common method of applying oil is for operators to use a hand tool to apply grease, or to directly apply the grease to the internal structure of the bearing by hand (wearing gloves).

[0004] The entire process relies mainly on manual labor, which first faces the problem of extremely low lubrication efficiency. Taking a common deep groove ball bearing as an example, the manual lubrication of a single bearing usually takes 5-15 minutes (the specific time depends on the bearing model and the operator's proficiency). If a batch assembly line or an emergency repair scenario is encountered, the manual lubrication process can easily become the "efficiency bottleneck" of the overall operation, directly leading to an extension of the equipment's online cycle or an increase in downtime due to malfunction.

[0005] Furthermore, manual lubrication inevitably leads to problems with improper application: due to the lack of standardized quantitative criteria (such as grease dosage and evenness of application), the amount of grease applied relies entirely on the operator's experience. In some cases, insufficient grease can result in inadequate lubrication inside the bearing, causing direct metal-to-metal friction during operation, which not only produces abnormal noise and vibration but also significantly shortens the bearing's lifespan. Conversely, excessive grease can be squeezed out of the sealing cavity during high-speed bearing operation, wasting grease and potentially causing additional resistance due to grease buildup, leading to localized overheating of the bearing, or even carbonization of the grease contaminating the bearing's interior and causing more serious equipment failure. Simultaneously, manual application cannot guarantee even distribution of grease on the raceway and rolling element surfaces, easily creating localized lubrication blind spots and posing a potential threat to the long-term stable operation of the equipment.

[0006] This traditional manual lubrication method not only restricts the efficiency of bearing housing replacement and installation, but also indirectly increases the cost and risk of failure in the later maintenance of the equipment due to the difficulty in controlling the standardization of operation. Utility Model Content

[0007] The purpose of this invention is to provide a device for accelerating the application of grease to bearing housings, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a device for accelerating the grease application of a bearing housing, comprising a lower cover, wherein the surface of the lower cover is provided with a semi-circular oil guide groove and an oil guide ring groove, the semi-circular oil guide groove and the oil guide ring groove are concentrically arranged and the semi-circular oil guide groove is connected to the oil guide ring groove, and the surface of the oil guide ring groove is provided with a plurality of oil outlet holes, thereby realizing simultaneous multi-directional oil replenishment of the bearing housing and greatly improving the grease application efficiency; The upper cover is sealed to the lower cover to prevent grease leakage and waste, and to ensure a clean oiling process. Both the upper and lower covers have a socket hole in the middle to facilitate the device being fitted onto the connecting shaft. The oil injection pipe is screwed to the upper cover and is connected to the semi-circular oil guide groove. After passing through the semi-circular oil guide groove and the oil guide ring groove, the grease is discharged from several oil outlet holes to replenish the bearing seat.

[0009] Furthermore, the lower cover has mounting holes on its side, and a handle is installed inside the mounting holes to facilitate the handling, positioning and disassembly of the device, thereby improving the ease of operation. The handle surface is fitted with an anti-wear sleeve to enhance the comfort of the grip.

[0010] Furthermore, the lower cover surface is provided with several threaded holes, and several hexagon socket bolts pass through the upper cover surface. The hexagon socket bolts are screwed into the threaded holes. The bolt connection method is simple to disassemble and assemble, and facilitates the maintenance and cleaning of the subsequent device.

[0011] Furthermore, the lower cover has an integrally formed grease nipple, which is connected to the oil outlet hole to precisely guide the grease to the bearing seat where it needs to be lubricated, thereby accelerating the lubrication process.

[0012] Furthermore, the oil injection pipe has a pagoda head, which connects the oil injection pipe to the oil pipe of the grease injector, allowing for quick connection and a tight connection that is not easily detached.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) Using the handle, the upper and lower covers are put onto the connecting shaft, the grease nipple is aligned with the bearing, and with the high-pressure quantitative grease pump and multi-channel grease nipple, the grease can be accurately delivered to the key contact areas of the bearing raceway, cage and rolling elements in one go, without the need for manual application point by point. Compared with traditional manual grease injection, this method can significantly shorten the lubrication operation time of a single bearing and improve bearing maintenance efficiency.

[0014] (2) This utility model solves the problems of low efficiency and non-standard manual lubrication of bearings, abandons the inefficient mode of manual brushing and hand application, and, in conjunction with a high-pressure quantitative oil pump, can realize automatic oiling as soon as the bearing is in place, eliminating the efficiency bottleneck of manual oiling. In view of the instability of manual judgment of oil volume by experience and the need to ensure uniformity by touch, the high-pressure quantitative oil pump can realize timed and quantitative oiling, avoiding insufficient lubrication due to insufficient oil volume or overheating resistance due to excessive oil volume, thus achieving comprehensive guarantee of production needs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Please see Figure 1-6 This utility model provides a technical solution: a device for accelerating the application of grease to a bearing housing, comprising a lower cover 4, wherein the surface of the lower cover 4 is provided with a semi-circular oil guide groove 10 and an oil guide ring groove 11, the semi-circular oil guide groove 10 and the oil guide ring groove 11 are concentrically arranged and the semi-circular oil guide groove 10 is connected to the oil guide ring groove 11, the surface of the oil guide ring groove 11 is provided with a plurality of oil outlet holes 12, the diameter of the semi-circular oil guide groove 10 is larger than that of the oil guide ring groove 11, and the plurality of oil outlet holes 12 are arranged in a ring, which can evenly inject grease into the bearing 15, making the grease injection process more controllable and reducing the error of manual grease injection; The upper cover 3 is sealed to the lower cover 4 to ensure that the grease flows along the semi-circular oil guide groove 10 and prevents the grease from leaking between the upper cover 3 and the lower cover 4. The upper cover 3 and the lower cover 4 are both provided with a sleeve hole 8 in the middle. The size of the sleeve hole 8 corresponds to the connecting shaft 16, so that the upper cover 3 and the lower cover 4 can be smoothly fitted onto the connecting shaft 16, and also play a positioning role for oil injection. The oil injection pipe 5 is screwed to the upper cover 3 and is connected to the semi-circular oil guide groove 10. After passing through the semi-circular oil guide groove 10 and the oil guide ring groove 11, the grease is discharged from several oil outlet holes 12 to replenish the bearing seat 14. The oil injection pipe 5 is convenient to connect to the oil injection pump.

[0019] In this embodiment, as Figure 1 and Figure 4 As shown, the lower cover 4 has a mounting hole 17 on its side. A handle 1 is installed inside the mounting hole 17. An anti-wear sleeve 2 is fitted onto the surface of the handle 1. The anti-wear sleeve 2 can be made of silicone to improve the grip comfort of the handle 1. Silicone also has an anti-slip effect, making it less likely for the carrying device to slip out of the hand.

[0020] In this embodiment, as Figure 1 and Figure 4 As shown, the surface of the lower cover 4 is provided with several threaded holes 6, and the surface of the upper cover 3 is provided with several hexagon socket bolts 7. The hexagon socket bolts 7 are screwed into the threaded holes 6. The surface of the upper cover 3 is provided with a concave hole to accommodate the hexagon socket bolts 7, which can prevent the hexagon socket bolts 7 from protruding from the upper cover 3. The multiple hexagon socket bolts 7 improve the stability and sealing of the connection between the upper cover 3 and the lower cover 4. When it is necessary to clean the semi-circular oil guide groove 10, the oil guide ring groove 11, and the oil outlet hole 12, the hexagon socket bolts 7 can be unscrewed.

[0021] In this embodiment, as Figure 2 As shown, the lower cover 4 has an integrally formed grease nipple 9, which is connected to the oil outlet hole 12.

The grease injection pipe 5 is quickly connected to the grease injector. Grease is injected from the injector through the grease injection pipe 5. The grease flows into the semi-circular guide groove 10 and then into the guide ring groove 11. Under pressure, the grease quickly fills the guide ring groove 11. The grease that enters the guide ring groove 11 is accurately delivered to the inside of the bearing 15 through the grease injection nozzle 9. The multi-channel grease injection nozzle 9 achieves all-round and uniform lubrication inside the bearing 15, avoiding local leakage or over-lubrication by manual grease injection.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
