Description

Technical Field

[0001] This utility model relates to the technical field of bearing oiling devices, and in particular to an oiling device for tapered roller bearings. Background Technology

[0002] Bearings, as key components in mechanical equipment, play a vital role in supporting rotating bodies, reducing friction, and transmitting loads. Regular and effective lubrication of bearings is one of the key measures to maintain their good performance and extend their service life.

[0003] In the prior art, a search revealed a Chinese patent disclosing "An oiling device for tapered roller bearings," application number "202320192912.8." This patent mainly includes a base, an outer frame connected to the middle of the base's top surface, an oil reservoir connected to the top of the outer frame, an opening on the top surface of the oil reservoir, support columns evenly spaced at the top of the base, a platform on the top surface of the support columns, a connecting plate connected to one side of the platform, a central plate connected to the end of the connecting plate, a motor connected to the bottom of the central plate, and the motor's output end passing through the central plate and connected to a rotating plate. A connecting pipe is connected to the bottom of the outer frame. While the above-mentioned oiling device uses a controller to open a valve during oiling, allowing the oil inside the oil reservoir to flow downwards along the connecting pipe, the motor starts and drives the rotating plate to rotate, causing the tapered nozzle at the end of the connecting pipe to perform a circular motion, thereby oiling the bearing placed on the platform. However, currently, bearing lubrication mostly uses lubricating grease. Due to the low fluidity of lubricating grease, the dripping method using the aforementioned connecting pipe results in slow flow of the grease within the connecting pipe, potentially leading to blockages. This makes it impossible to ensure timely and sufficient lubrication of the bearing, hindering the completion of the bearing lubrication process. Therefore, this invention provides an oiling device for tapered roller bearings to solve the problems mentioned in the background art. Utility Model Content

[0024] Reference Figure 1-4 This utility model discloses an oiling device for tapered roller bearings, comprising an operating table 1, an oil tank 2 fixedly connected inside the operating table 1, a mounting bracket 6 fixedly connected to the bottom of the operating table 1 below the oil tank 2, a first electric push rod 7 fixedly connected to the bottom of the mounting bracket 6, a first piston plate 8 slidably connected inside the oil tank 2, the top end of the piston rod of the first electric push rod 7 being fixedly connected to the first piston plate 8, a detachable top cover 3 installed on the top of the oil tank 2, a positioning ring 5 fixedly connected to the top of the top cover 3, and multiple oil outlet holes 4 evenly opened inside the top cover 3 and inside the positioning ring 5.

[0025] The tapered roller bearing is positioned inside the locating ring 5. The first electric push rod 7 moves the first piston plate 8 upward, and the moving first piston plate 8 squeezes out lubricating grease through the oil outlet 4. The lubricating grease can adhere to the bearing to complete the lubrication process. By adopting a multi-hole oil outlet method, it is beneficial to ensure the uniformity and efficiency of oiling the bearing. Furthermore, the cooperation between the first electric push rod 7 and the first piston plate 8 in squeezing out the lubricating grease facilitates better control of the oil application, avoiding grease waste and ensuring that the bearing receives adequate lubrication to guarantee a stable bearing service life.

This facilitates the oiling work of bearings of different specifications, making it more flexible and applicable.

[0027] To maintain sufficient grease in the upper oil tank 2, a replenishment oil tank 9 is fixedly connected to the top of the operating platform 1 and to one side of the upper oil tank 2. A fixing frame 10 is fixedly connected to the top of the operating platform 1, and a second electric push rod 11 is fixedly connected to the top of the fixing frame 10.

[0028] When lubricating oil needs to be replenished, the second electric push rod 11 will push the second piston plate 12 to transport the lubricating oil in the oil replenishment tank 9 to the upper oil tank 2 through the oil delivery pipe 13.

[0029] For ease of operation, a foot switch 16 is provided at the bottom of the operating table 1. The operator can control the first electric push rod 7 by stepping on the foot switch 16, thereby realizing the oiling operation. A transparent plate 15 is embedded inside the oil tank 2 and above the operating table 1. The operator can see the remaining amount of oil inside the oil tank 2 through the transparent plate 15 and replenish it in time.

[0030] Working principle: The tapered roller bearing is positioned inside the locating ring 5. The first electric push rod 7 moves the first piston plate 8 upward. The moving first piston plate 8 squeezes out lubricating grease through the oil outlet 4. The lubricating grease adheres to the bearing, completing the lubrication process. By adopting a multi-hole oil outlet method, the uniformity and efficiency of oiling the bearing are ensured. Furthermore, the cooperation between the first electric push rod 7 and the first piston plate 8 in squeezing out the lubricating grease facilitates better control of the oil application, avoiding grease waste and ensuring that the bearing receives adequate lubrication to guarantee a stable bearing service life.
