Description
Technical Field
The utility model belongs to the technical field of mechanical lubrication, and particularly relates to a lubricating oil level determining structure of a closed transmission device.
Background
The lubricant level determining mode of the transmission device has various forms, and a common overflow screw plug determining method is that an overflow screw plug is arranged at the lubricant level position theoretically required by the transmission device, the overflow screw plug is opened during oiling, and the oil flows out from the overflow screw plug during filling. In the oil level determination method, a transparent oil level gauge is arranged near the theoretical oil level surface of the transmission device, and the oil level of lubricating oil is observed by naked eyes during oiling. The flexible oil level determining method is that the flexible oil level is provided with the maximum and minimum lines of the oil level of the lubricating oil, and the oil level of the lubricating oil is preferably between the two lines when the flexible oil level is oiled by inserting the oil level meter into the special-shaped oil level channel for many times. The rigid oil measuring scale determining method is that the rigid oil measuring scale is provided with maximum and minimum lubricant level lines, and the oil measuring scale is inserted into the linear oil measuring channel several times during oil filling, so that the lubricant level is between the two lines. The oil level sensor determining method is to utilize the change of the capacitance between the sensor shell and the sensing electrode caused by the lubricant entering the transmission device and to convert the change into current change to check the lubricant level in the transmission device.
The various oil level determining modes of the transmission device have advantages and disadvantages and are suitable for different working occasions. The overflow screw plug determination method is simplest, has the least material consumption and is most economical, but a certain manual operation space is reserved, and the overflow screw plug determination method is generally suitable for an exposed transmission device. The oil scale method has the best intuitiveness, but an observation channel is reserved, so that the oil scale method is convenient for artificial observation and is generally suitable for observing a transmission device with better sight. The reliability of the flexible dipstick determination method and the rigid dipstick determination method is highest, but the operation is repeated for a plurality of times when lubricating oil is added, which is time-consuming and labor-consuming, and is generally suitable for a transmission device without maintenance or with less maintenance. The oil level sensor determination method is most convenient and visual, and can display the oil level of the lubricating oil on a terminal interface in a digital display mode, but has lower reliability, high price and difficult calibration, and is generally suitable for a transmission device with a better use environment such as smaller impact vibration.
The armored vehicle is used as combat equipment, all transmission devices are basically arranged at the bottommost part of the vehicle, and the periphery of the transmission devices is generally wrapped by functional components such as a power cabin, a vehicle body, a floor, a gun turret, a bullet frame and the like, so that the manual operation space is small, the sight line is poor, the daily use environment is bad, the conventional transmission device oil level determining mode is extremely inconvenient to operate or cannot be used at all in the environment, and the daily maintenance and the maintenance of the equipment at ordinary times and in the war are seriously influenced.
Disclosure of utility model
The technical problems to be solved by the utility model are as follows: the prior transmission oil level determining mode is not suitable for armored vehicles, and seriously affects the daily maintenance of equipment at ordinary times and in war time.
In order to solve the technical problems, the specific technical scheme of the utility model is as follows:
The utility model provides a lubricating oil level of closed transmission determines structure, transmission box adopts the cast mode shaping, transmission box's side and bottom surface are provided with bellied built-in oil duct 15, and inside opening sets up in lubricating oil theory oil level line 12 department, and outside opening sets up in box bottom next to drain plug screw 17 department, and outside opening is provided with overflow plug screw 11.
The utility model has the beneficial effects that: by utilizing the principle of communicating vessels, lubricating oil higher than a theoretical oil level line is drained to the outside of the vehicle through the built-in oil duct of each structural member, so that the purpose of accurately determining the lubricating oil quantity of the closed transmission device of the armored vehicle outside the vehicle is achieved. The method can successfully solve the problem that the lubricant amount of the closed transmission device of the multi-type armored vehicle is difficult to determine, particularly the problem that the lubricant of the transmission device under the power cabin cannot be replaced, greatly reduces the daily maintenance of equipment at ordinary times and in war time, and can be popularized and applied.
