Description

TECHNICAL FIELD

[0001] The utility model belongs to gear drive lubrication technical field, concretely is a hand -held open gear lubricating device. BACKGROUND

[0002] Open gear is a common mechanical transmission component, and is mostly applied to large machinery under low speed and heavy load, such as ship lock miter gate hoist, mine equipment, wind power generation, etc., and the running state thereof determines the safe operation of equipment. Good lubrication is an important prerequisite for guaranteeing the safe operation of the gear transmission system, and if the open gear tooth surface is insufficiently lubricated, dry friction between the tooth surfaces of the open gear will occur, which will accelerate the wear of the gear system, cause abnormal noise of the gear, reduce the service life, and even cause tooth surface gluing phenomenon, and even tooth breakage, which is easy to cause major safety hazards. Regular and effective lubrication of the open gear can not only ensure the formation of an oil film between the tooth surfaces, reduce the friction coefficient between the teeth, reduce friction loss, but also accelerate heat dissipation to protect the tooth surface base material and improve the service life of the gear. At present, there are three kinds of lubrication modes for large open gears at home and abroad, one is manual smearing of lubricating grease, which has good flexibility, low cost and less waste of lubricating grease, but the subjective factors have a great influence on the lubrication quality, and it is difficult to guarantee the lubrication quality, and it is easy to be affected by the operation space, and it is not convenient to realize manual smearing of lubricating grease in narrow space. The second is spray lubrication, which sprays lubricating grease to the tooth surface needing lubrication through a pressurizing and heating device. This mode is widely used and mature in technology, but the manufacturing and daily maintenance cost is high, the viscosity of the lubricating grease is different, and the lubricating grease is easy to appear wire drawing phenomenon in the heating and spraying process, which pollutes the environment. The third is oil wheel lubrication, that is, the lubricating grease is brought into the gear meshing area through the oil wheel, and the lubrication effect is achieved through the mutual meshing of the transmission open tooth. This mode has good stability and low technical requirements, but the loss of lubricating grease is large, the oil wheel dripping phenomenon is serious and easy to cause pollution, and a certain installation space is needed to arrange the corresponding oil wheel.

[0003] To solve the above problems, the relevant technical personnel has carried out a lot of research to improve the lubricating effect. For example, patent No. CN201921167668.X discloses a gear spraying lubricating oil device, which comprises a spraying chamber, a conveying track and a spraying device. The device automatically sprays lubricating oil to the surface of the gear through the spray head. Patent No. CN202222780761.6 discloses an open gear automatic lubricating device for ship lock miter gate hoist. The device uses a lubricating pump station connected to an external oil wheel through a lubricating pipeline. The external oil wheel is installed on the side of the open gear through a mounting bracket and is engaged with the open gear to be lubricated to realize the lubrication of the open gear. The above two lubricating devices can meet the lubrication demand of the open gear to a certain extent, but they will cause a lot of grease waste and cannot dispose the waste grease in time, which will inevitably cause environmental pollution. At the same time, these two lubricating methods need a certain space for installing related equipment on site. In the case where the space condition is not allowed, these two lubricating methods are no longer applicable. Utility model content
