Problems solved by technology

The transmission used for wide-body mining vehicles is the transmission of ordinary dump trucks. This type of transmission is used in ordinary vehicles with good road conditions and good gearbox lubrication; for wide-body mining vehicles, due to the harsh environment, steep slopes and bends , especially when the slope is large, splash lubrication cannot be carried out normally, and forced lubrication may also fail because the lubricating pump cannot absorb lubricating oil, and gear failure phenomena such as abnormal wear and gluing of constant meshing gears and third and fourth gears occur; simultaneous meshing gears The temperature rises rapidly, and through heat transfer, the temperature of the lubricating oil rises sharply, and the lubricating oil accumulated in the auxiliary tank transfers the temperature to the planetary gears, and the heat cannot be discharged in time, causing pitting of the planetary gears due to excessive temperature

Embodiment Construction

[0013] The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.

[0014] figure 1 Shown is the structural representation of the present invention.

[0015] The present invention adds an external lubricating system on the basis of the existing transmission lubricating system. The external lubricating system uses an external lubricating pump 2 as a power source and an angle switch 3 as a control element. Slope value, the external lubrication pump 2 is turned on by itself, and the constant meshing gear and the third and fourth gears of the gearbox are lubricated by spray nozzles. When the slope is less than the set value, the angle switch 3 is turned off, and the gearbox relies on its own internal lubrication system.

[0016] The external lubrication system includes a filter 1, an external lubrication pump 2, an angle switch 3, a one-way valve 4, a cooler 5, an oil circuit 6, an oil suction joint 7, a nozzle 8, a g...

Abstract

The invention discloses an external lubrication device for a transmission and a method. An external lubrication system is added on the basis of an existing transmission lubrication system. The external lubrication device comprises an external lubrication pump and an angle switch. The external lubrication pump is used as a power source of the external lubrication system. The angle switch is used as a control element. When a vehicle reaches the set slope value in the operation process, the external lubrication pump starts by itself, and normally-engaged gears, the third-gear gear and the fourth-gear gear of the transmission are spattered and lubricated through spray nozzles. When the gradient is smaller than the set value, the angle switch is turned off, and the transmission is lubricated through an internal lubrication system of the transmission. The external lubrication device is simple in structure, convenient to operate, high in reliability, capable of effectively solving the lubrication problem under the condition that a wide-body mining vehicle climbs a slope in a heavy-loaded manner, and capable of prolonging the service life of the transmission.

Description

technical field [0001] The invention relates to a gearbox lubricating device and method, belonging to the technical field of gearbox lubrication. Background technique [0002] The lubrication system is an integral part of the transmission. At present, transmission lubrication basically realizes lubrication and cooling through the combination of splash lubrication and forced lubrication. The transmission used for wide-body mining vehicles is the transmission of ordinary dump trucks. This type of transmission is used in ordinary vehicles with good road conditions and good gearbox lubrication; for wide-body mining vehicles, due to the harsh environment, steep slopes and bends , especially when the slope is large, splash lubrication cannot be carried out normally, and forced lubrication may also fail because the lubricating pump cannot absorb lubricating oil, and gear failure phenomena such as abnormal wear and gluing of constant meshing gears and third and fourth gears occur; ...
