“Gear refers to a mechanical element with gears on the rim that continuously meshes to transmit movement and power. It is extremely widely used in mechanical transmission and the entire mechanical field. Gears and gear oils complement each other and are indispensable. Gear is the most important transmission power transmission mechanism gear in machinery. Gear oil is used in various gear transmissions to prevent tooth surface wear, scratches, sintering, etc. to extend its service life and improve the efficiency of power transmission. Let’s first understand the gear oil.

Gear is the most important transmission power transmission mechanism gear in machinery. Gear oil is used in various gear transmissions to prevent tooth surface wear, scratches, sintering, etc. to extend its service life and improve the efficiency of power transmission. Let’s first understand the gear oil.
Gear oil is mainly based on petroleum lubricating oil base oil or synthetic lubricating oil, and is an important lubricating oil prepared by adding extreme pressure anti-wear agent and oiliness agent. Used in various gear transmissions to prevent tooth surface wear, scratches, sintering, etc., to extend its service life and improve the efficiency of power transmission. It has good anti-wear, load resistance and suitable viscosity. Gear oils are divided into two categories: automotive gear oils and industrial gear oils. Whether in the field of automotive oils or industrial oils, one item that car owners will focus on when maintaining their cars is gear oil. Therefore, gear oil is a very important product in two vehicles. However, as the service life of the equipment increases and the use environment changes, the original recommended oil products will not be applicable. The selection of gear oil according to the actual situation and specific equipment is an important link to ensure continuous good production. Next, the editor of Gongminwang will introduce to you how the ultrasonic liquid level sensor can effectively monitor the gear oil level.
What is the damage of lack of gear oil?
What is the most afraid of the reducer? The most feared thing is that the gear oil leaks out unknowingly. After the lack of oil, it is easy to damage the bearings and gears. In serious cases, the entire gearbox can be scrapped, which not only loses money, but also delays the construction period.
How to check whether the gear oil is lacking?
For the slewing motor reducer, generally there is an oil dipstick above the slewing motor. You can pull out the dipstick to observe whether the gear oil level is between the two observation holes at the bottom of the scale. The small hole at the bottom of the scale represents the lowest liquid level. The upper small hole represents the highest liquid level, and the gear oil level between the two observation holes is normal. When the liquid level is lower than the bottom hole, the gear oil should be refilled in time. For the walking motor reducer, since there is no oil dipstick for daily inspection, it is necessary to closely observe whether there is any oil leakage after changing the gear oil, and check and replace the oil seal and replenish the gear oil in time when the oil leakage is found.
Precautions for changing gear oil
Unscrew the oil level inspection hole screw plug, check whether the oil level reaches the specified oil level, and check whether the hole side scale is between 0 and 15 mm. If the amount of oil is insufficient, make up the gear oil to make the oil level reach the specified scale and check for oil leakage. When changing the gear oil, the vehicle should be started and rotated or traveled a certain distance to increase the temperature of the transmission gear oil. When the gear oil is still warm, unscrew the oil drain plug to drain the gear oil. When installing the oil drain plug, note that the oil drain plug of some models is magnetic. The iron powder adsorbed on the plug should be removed before screwing it on firmly. Then add new gear oil that meets the requirements until the gear oil overflows from the oil level inspection hole, and install the inspection hole plug. For some types of vehicles, such as Jetta cars, the transmission gear oil does not need to be replaced during use, just check for leakage. If leakage is found in the transmission, the leakage should be repaired and gear oil should be added.
Therefore, to maintain a reasonable liquid level in the gear oil tank, in general, the liquid level control of the centralized liquid supply system should be within the capacity of the liquid tank. In order to better detect the gear oil level, the mining network recommends a MaxBotix liquid level ultrasonic sensor MB7380.
The ultrasonic sensor is a sensor developed by using the characteristics of ultrasonic waves, and has the advantages of accurate measurement, wide detection range, flexible use, and easy maintenance. The hrxl-maxsonar-wr sensor line provides high-precision and high-resolution ultrasonic proximity detection and ranging in the air. The sensor line is characterized by 1mm resolution, target size and operating voltage compensation. In order to improve accuracy, better reject external noise sources, temperature compensation of internal speed and optional external temperature compensation. The hrxl-maxsonar-wr/wrc model is available in 5m or 10m models. This ultrasonic sensor can detect objects ranging from 1 mm to 30 cm. Objects with a range of more than 30 cm are usually reported as 30 cm. The output format of the interface is pulse width, analog voltage and digital serial in RS232 (MB7360 series) or TTL (MB7380 series). Factory calibration is standard. For applications that need to be used, the hrxl-maxsonar-wr sensor is a cost-effective solution. Accuracy range-search, low voltage operation, space saving, low cost, and weather forecast resistance of IP67.
