Description
Technical Field
The present invention relates to a lubrication system, and more particularly to a lubrication system for an open gear.
Background
The open gear is widely applied to large-scale equipment in the industries of ocean engineering, electric power, mines, cement, steel, chemical engineering, paper making and the like. However, since the open gear has no dust cover or housing, the gear is exposed to the outside and is liable to fall into dust, chips, etc. during transmission, so that the gear is not in good working condition, and it is necessary to improve the lubrication condition of the gear to avoid the wear of the abrasive due to poor lubrication of the gear. The existing open gear lubrication modes comprise manual lubrication, oil cup filling lubrication, oil-gas lubrication and the like.
The manual lubrication is used for smearing the lubricating oil on the tooth surfaces of the open gear in a manual smearing mode, however, the diameter of the heavy open gear reaches several meters along with the continuous increase of the diameter of the open gear, and the traditional lubricating mode of manually smearing the lubricating oil has high labor intensity of operators and certain danger; in addition, in the middle-term maintenance process, because the open gear is in the meshing state, lubricating oil cannot be applied to the tooth surface of the gear at the meshing position in the current state, the application work cannot be completed on all the tooth surfaces at the meshing position and the tooth surfaces at the non-meshing position at one time, and the application work needs to be performed again after the gear is rotated for the tooth surfaces at the meshing position, so that the application process is complex, and the maintenance cost is high.
For example, patent document 1(CN204533469U) discloses a rolling type lubricator, which is a lubrication type of an oil cup filling type lubricator, in which an outer conical inner ball valve port 9 is provided at the lower end of an oil cup 1, and a guide ball 5 is provided on the inner spherical surface of the outer conical inner ball valve port 9. The oil cup is characterized in that a positioning movable piston 4 and a horizontal support plate 7 are sequentially arranged in the oil cup 1 from top to bottom, the positioning movable piston 4 is composed of a horizontal pressing plate 401 corresponding to the horizontal support plate 7 and a positioning column 402 arranged on the horizontal pressing plate 401, the positioning column 402 is sleeved with a spring 6, the top end of the positioning column 402 extends out of an upper cover plate 2 of the oil cup 1 through a longitudinal through hole, a limiting spring 8 is arranged between the horizontal support plate 7 and the flow guide ball body 5, and the horizontal support plate 7 is of a hollow structure or forms a gap with the inner wall of the. When the lubricating grease is used, grease is placed between the horizontal pressing plate 401 and the horizontal supporting plate 7, the grease penetrates through the horizontal supporting plate 7 under the pressure action of the horizontal pressing plate 401 to flow downwards and is gathered to the conical bottom surface flow guide ball body 5, and the flow guide ball body continuously rolls, so that lubricating grease continuously falls onto the surface of the open gear. However, for the lubricating mode, due to the lack of the oil quantity feedback unit, the external world cannot know the oil content in the oil cup, and when the oil is lack, an alarm cannot be sent to the external world to supplement the oil in time, so that the open gear is subjected to dry friction; and under the condition that the oil cup contains the oil, the oil cup can continuously fill the oil into the open gear, and the lubricating system cannot automatically control the oil filling time.
Patent document 2(CN204358071U) discloses an open gear oil-gas lubrication system, in which an air pressure-regulating filter device 2, a pneumatic barrel pump 7, an oil-gas mixing block 8, an oil-gas distributor 9, an oil-gas nozzle 10, etc. are provided, the air pressure-regulating filter device 2 has two gas outlet ends, the lubrication system has two compressed air passages, one passage leads to the pneumatic barrel pump 7 for providing power for the pneumatic barrel pump 7 to pump lubricating oil, the other passage directly leads to the oil-gas mixing block 8, the lubricating oil pumped by the pneumatic barrel pump 7 is mixed with the compressed air from the air pressure-regulating filter device 2 in the oil-gas mixing block 8 to form an oil-gas mixed flow, and the oil-gas mixed flow is distributed by the oil-gas distributor 9 and then is sprayed to the tooth surface of the open gear driving wheel by the oil-gas nozzle 10 to form an oil film. In the lubricating system, the electric control device controls the opening and closing of electromagnetic valves arranged in each oil and gas passage to realize automatic control. In the utility model, the lubricant forms an oil film on the open gear in the form of spraying oil mist, and is easy to be scattered to other spaces outside the gear surface in the spraying process, thereby being easy to cause waste and air pollution; moreover, when the electric control device fails, the lubricating system cannot work.
Therefore, it is an urgent technical problem in the art to provide a lubrication system for an open gear that is reliable in use and has high lubrication efficiency.
