Description

Technical Field

[0001] The utility model relates to the technical field of mechanical transmission, in particular to a gear lubrication device, specifically to a lubricating oil coating device for a vibration-proof open gear. Background Art

[0002] Large heavy-load ball mills, tube mills and other material grinding equipment usually use small gears to drag large gears for transmission. They are open gears with the characteristics of heavy loads, poor working environment, serious gear damage and poor operating reliability. The existing commonly used lubrication technologies include jet lubrication technology, which uses oil pumps and air pumps to connect lubricating oil and compressed air to nozzles through pipes, and atomizes the oil through compressed air to form a high-speed jet, which is sprayed onto the ball mill gears to achieve the purpose of lubrication. This technology has problems such as poor gear lubrication effect and serious oil waste. A lubrication device that can save oil and use high-viscosity lubricating oil is urgently needed on site. To this end, the utility model patent with publication number "CN210318445U" applied by the applicant on March 30, 2019 discloses a lubricating oil coating device for large open gears, including a large gear and a small gear meshing with each other, and a meshing oil coating wheel is also provided on the upper side of the small gear, and the oil coating wheel is connected to a lubricating oil supply device, and the oil coating wheel is fixed on the mounting base of the small gear through a bracket provided, and it is disclosed that the bracket is provided with an adjustment mechanism for adjusting the meshing clearance between the small gear and the oil coating wheel. Although the adjustment mechanism can adjust the clearance between the small gear and the oil coating wheel, it can only be adjusted in advance according to needs and cannot complete real-time adjustment.

[0003] In actual use, due to the harsh working environment and heavy load of large open gears, such large open gears often experience excessive vibration during operation, which causes the oiling wheel to collide with the pinion and often causes damage to the oiling wheel.

[0004] Therefore, when using high-viscosity lubricating oil to lubricate large involute gears, how to ensure the lubrication effect while adapting to the lubrication device that may damage the lubrication system due to excessive gear vibration. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a novel lubricating oil coating device for vibration-proof open gears which can use high-viscosity lubricating oil, has good economy and can adapt to gear vibration tolerance.

[0006] The utility model is realized by the following technical scheme, and provides a lubricating oil smearing device for vibration-proof open gears, comprising a large gear and a small gear meshing with each other, a meshing smearing wheel is also provided on the upper side of the small gear, the smearing wheel is connected to a lubricating oil supply device, the smearing wheel has a plurality of small teeth meshing with the small gear, each meshing surface of the small tooth and the small gear is provided with a plurality of oil outlet holes or oil outlet slits, the inside of the smearing wheel has a cavity connected with the oil outlet hole or the oil outlet slit, the smearing wheel is installed on a floating mechanism on a first bracket through a hollow shaft, and the smearing wheel moves around the hollow shaft under the drive of the small gear. The shaft rotates, and the hollow shaft has a cavity connected to the inside of the oiling wheel and a hole for the lubricating oil supply device. The floating mechanism includes a pair of hollow shaft mounting seats that can float up and down, and both ends of the hollow shaft mounting seats have guide holes matching the guide rods. A support rod is provided at the bottom of the hollow shaft mounting seat, and the support rod has a stopper. The support rod is nested and installed in a sliding hole provided on the second fixed bracket through the stopper. A compression spring is nested and installed at the lower part of the support rod. The guide rod and the second fixed bracket are both fixedly installed on the first bracket, and the first bracket is fastened to the mounting base of the pinion.

[0007] After adopting the above scheme, the utility model conveys the lubricating oil to the oil outlet hole or oil outlet gap of the small tooth of the oiling wheel, and during the rotation of the small gear, the oiling wheel is pushed to rotate. At the same time, the lubricating oil overflowing or seeping from the upper surface of the oiling wheel is smeared on the meshing tooth surface of the small gear, and in the process of the small gear driving the large gear to rotate, the lubricating oil smeared on the meshing surface of the pinion gear is smeared on the meshing surface of the large gear, thereby realizing the lubricating oil smearing work of the large gear and the small gear. This smearing method does not require atomization, so even lubricating oil with high viscosity can be smeared, and in the process of smearing the lubricating oil, only the meshing surface that needs lubrication is smeared, and no waste of lubricating oil is caused. In the utility model, the oiling wheel is fixed to the first bracket by a floating bracket, and the first bracket is fixed to the mounting base of the small gear. In this fixing method, when the small gear vibrates out of tolerance or shifts, the oiling wheel can automatically adjust its position under the drag of the floating device to maintain its relative position with the small gear, so as to avoid the oiling wheel being damaged by the small gear with excessive vibration.

[0008] Preferably, the mounting mechanism of the floating mechanism is provided with an adjustment mechanism for adjusting the meshing clearance between the pinion and the oiling wheel. This solution can adjust the clearance between the pinion and the oiling wheel by providing an adjustment mechanism, can be flexibly used for lubrication of pinions with different tooth shapes, and can better control the amount of lubricating oil applied and the stress of the pinion and the oiling wheel.

[0009] Preferably, the lubricating oil supply device comprises an oil tank, an oil pump, an oil pipe and a controller. The oil pump delivers the lubricating oil in the oil tank to the oiling wheel through the oil pipe, and the start and stop of the oil pump is controlled by the controller. This preferred solution can adjust the lubrication time and the amount of lubricating oil by controlling the oil pump with the controller.

[0010] Preferably, a vibration sensor is installed on the first bracket, and the vibration sensor is electrically connected to the controller. In this solution, the vibration sensor installed on the first bracket can effectively detect the vibration value of the pinion and the first bracket. When the vibration value is out of tolerance, the vibration out-of-tolerance signal collected by the vibration sensor is alarmed through the controller, and the operation and maintenance personnel are notified in time to quickly handle it to avoid the expansion of the accident.

[0011] Preferably, the controller is a controller controlled by PLC, relay or single chip. As the easiest to implement solution, this preferred solution can be applied to the control of lubricating oil application of large open gears under various adjustments.

[0012] Preferably, the hollow shaft is provided with a plurality of holes connected to different oil outlet holes or oil outlet slits on the surface of the oiling wheel through different pipes. This preferred solution can improve the uniformity of lubricating oil on the surface of the oiling wheel, thereby improving the lubrication uniformity of the surface of the ultra-wide gear.

[0013] To sum up, the entire lubricating oil transmission and lubrication process of the utility model does not require pressurized atomization, and can use lubricating oil with higher viscosity, thereby increasing the oil film strength, improving the lubrication effect, and effectively protecting the gears. The floating mechanism provided can effectively improve the problem of easy damage to the oiling wheel due to excessive gear vibration. In addition, the beneficial effects of the utility model also include precise point-to-point lubrication of the lubricating oil, and no oiling of other non-meshing non-working surfaces, which maximizes the efficiency of lubricating oil use, reduces waste, reduces the amount of lubricating oil used, saves costs, and has the beneficial effects of long service life of the oiling wheel, easy implementation, low cost and good stability.
