[0001] This case is a divisional application of the parent case with the patent application number 202111426612.3, application date 2021-11-25, and name "Forced Lubrication Device for Vibrating Wheel Vibrating Bearing". Technical Field

[0002] The invention relates to the technical field of vibration wheels, in particular to a forced lubrication device for a vibration bearing of a vibration wheel. Background Art

[0003] Vibratory rollers are one of the most commonly used construction machines in earthwork and road construction, primarily used for compacting sites or roads. Their operating principle is that two eccentric masses rotate in response to the driver, creating the excitation force from the eccentric forces. The eccentric masses are welded to the vibrating shaft and supported by four vibrating bearings. During vibration operation, the vibrating bearings are subjected to significant pulse loads, requiring adequate lubrication to ensure proper operation.

[0004] The existing lubrication method mainly uses an oil box to bring oil to the inner plate of the vibrating wheel during its operation, performing wall flow lubrication. However, wall flow lubrication does not fully lubricate the vibrating bearing, generates a lot of heat, and easily shortens the service life of the vibrating bearing.

[0005] Based on this, the present invention designs a vibrating wheel vibrating bearing forced lubrication device to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a vibrating wheel vibrating bearing forced lubrication device to solve the above technical problems.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a forced lubrication device for a vibrating wheel vibrating bearing, comprising a wheel rim, a fixed plate, a vibrating device and a web plate arranged inside the wheel rim, the web plate being connected to a mounting block, the mounting block being connected to a vibrating bearing, an oil pump being provided on a side wall of the mounting block, the oil pump being connected to a first one-way valve and a second one-way valve, the mounting block being provided with an excitation chamber for storing lubricating oil, the first one-way valve being connected to the excitation chamber through an oil inlet pipe, the second one-way valve being connected to the vibrating bearing through an oil outlet pipe, the side wall of the fixed plate being provided with a first stopper and a second stopper for controlling the oil suction and discharge of the oil pump.

[0008] Preferably, the vibration device includes a central shaft, eccentric modules are respectively sleeved on both ends of the central shaft, the vibration bearing is sleeved on the outer wall of the eccentric module, and a driver for rotating the central shaft is provided on the fixed plate.

[0009] Preferably, the eccentric module includes a connecting shaft and an eccentric block sleeved on the connecting shaft, the vibration bearing is sleeved on the outer wall of the connecting shaft, and the eccentric block is located in the excitation chamber.

[0010] Preferably, the first stopper and the second stopper are respectively provided with an inclined surface.

[0011] Compared with the existing technology, the present invention has the following advantages: with each rotation of the vibrating wheel, the oil pump, under the action of the first and second stops, completes one operation of sucking oil from the excitation chamber and forcibly lubricating the vibrating bearing. This avoids the problem of the vibrating bearing's service life being shortened due to insufficient lubrication under large pulse loads. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] Example:

[0021] See also Figure 1-4 The present invention provides a technical solution: a vibrating wheel vibrating bearing forced lubrication device, comprising a wheel rim 1, a fixed plate 2, a vibrating device 3, and a web 4 disposed within the wheel rim 1. The web 4 is connected to a mounting block 5, which is connected to a vibrating bearing 6. An oil pump 7 is disposed on the sidewall of the mounting block 5. The oil pump 7 comprises a housing 21, a spring 23 disposed within the inner cavity of the housing 21, and a valve core 22. The oil pump 7 is connected to a first one-way valve 8 and a second one-way valve 9, both of which are connected to the inner cavity of the housing 21. The mounting block 5 is provided with an excitation chamber 10 for storing lubricating oil. The first one-way valve 8 is connected to the excitation chamber 10 via an oil inlet pipe 11, and the second one-way valve 9 is connected to the vibrating bearing 6 via an oil outlet pipe 12. The sidewall of the fixed plate 2 is provided with a first stopper 13 and a second stopper 14 for controlling the oil suction and discharge of the oil pump 7. When the vibrating wheel is rolling, the oil pump 7 mounted on the mounting block 5 rolls in a circular motion. The fixed plate 2 is fixed to the roller body and does not rotate with the vibrating wheel rim 1. With each rotation of the vibrating wheel, the valve core 22 on the oil pump 7 contacts the first stop 13 and the second stop 14, respectively. When the vibrating wheel rotates in the forward direction, the oil pump 7 first contacts the first stop 13. When the oil pump 7 reaches the first stop 13, the valve core 22 on the oil pump 7 is squeezed. As the oil pump 7 passes the first stop 13, the valve core 22 on the oil pump 7 moves toward the fixed plate 2 under the action of the spring 23. At this point, the oil pump 7 draws lubricating fluid from the excitation chamber 10 into the inner cavity of the housing 21. When the oil pump 7 reaches the second stop 14, the valve core 22 on the oil pump 7 is squeezed, injecting lubricating fluid from the inner cavity of the housing 21 into the vibrating bearing 6. With each rotation of the vibrating wheel, the vibrating bearing 6 is lubricated once. This forced lubrication of the vibrating bearing 6 during forward rotation extends the service life of the vibrating bearing 6.

[0022] When the vibration wheel rotates in the opposite direction, the oil pump 7 first contacts the second stopper 14. When the oil pump 7 rotates to the second stopper 14, the valve core 22 on the oil pump 7 is squeezed. When the oil pump 7 passes the second stopper 14, the valve core 22 on the oil pump 7 moves to the side close to the fixed plate 2 under the action of the spring 23. At this time, the oil pump 7 draws the lubricating fluid from the excitation chamber 10 into the inner cavity of the shell 21. When the oil pump 7 rotates to the first stopper 13, the valve core 22 on the oil pump 7 is squeezed, and the lubricating fluid is injected from the inner cavity of the shell 21 into the vibration bearing 6. The vibration bearing 6 is lubricated once every rotation of the vibration wheel. When the vibration wheel rotates in the opposite direction, the vibration bearing 6 is forced to be lubricated in the above manner, thereby extending the service life of the vibration bearing 6.

[0023] Specifically, the vibration device 3 includes a central shaft 15, with eccentric modules 16 mounted on each end of the central shaft 15. The vibration bearing 6 is mounted on the outer wall of the eccentric modules 16. The fixed plate 2 is provided with a driver 17 for rotating the central shaft 15. The driver 17 drives the central shaft 15 to rotate, thereby rotating the eccentric modules 16, thereby generating an exciting force.

[0024] Specifically, the eccentric module 16 includes a connecting shaft 19 and an eccentric block 20 sleeved on the connecting shaft 19 . The connecting shaft 19 is connected to the central shaft 15 . The vibration bearing 6 is sleeved on the outer wall of the connecting shaft 19 . The eccentric block 20 is located in the excitation chamber 10 .

[0025] Specifically, the first stopper 13 and the second stopper 14 are each provided with an inclined surface 18. The inclined surface 18 provides a smooth transition. When the first stopper 13 or the second stopper 14 contacts the valve core 22 of the oil pump 7, the valve core 22 of the oil pump 7 is gradually pressed into the housing 21. This reduces the impact caused by the contact between the valve core 22 of the oil pump 7 and the first stopper 13 or the second stopper 14, thereby extending the service life of the oil pump 7.
