What oil should be added to the gearbox? Comprehensive analysis of gear oil selection and usage guidelines

As the core component of mechanical equipment, the gearbox’s selection of lubricating oil is directly related to the equipment life and operating efficiency. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the selection criteria, common problems and maintenance suggestions for gearbox lubricants.

1. Classification and characteristics of gearbox oil

2. Recent hot topics of discussion

According to the data analysis of the entire network, the hot topics about gearbox lubrication in the past 10 days mainly focus on the following aspects:

1.Performance comparison of synthetic oil and mineral oil: Most technical forums recommend the use of synthetic gear oil for heavy-duty equipment. Although the cost is higher, it can significantly extend the oil change interval.

2.Oil selection in extreme environments: The selection of gear oil for Arctic scientific research equipment and desert operation machinery has become a hot topic, requiring special attention to low-temperature fluidity and high-temperature stability.

3.Oil mixing problem: Multiple cases have shown that mixing gear oils of different brands has led to an increase in sediment. Experts recommend cleaning the gear oil thoroughly before changing the oil.

3. Gear oil selection standards

4. Frequently Asked Questions

Q: Does the gear oil need to be replaced immediately if it turns black?

A: Not necessarily. Gear oil will gradually darken due to oxidation during use. Professional testing should be carried out to determine whether it needs to be replaced, rather than just judging by color.

Q: Can oil products of the same model from different brands be mixed?

A: Not recommended. Additive formulations from different manufacturers may present a risk of reaction, which may result in reduced lubrication performance.

Q: How to judge whether the gear oil needs to be replaced?

A: There are three main indicators to observe: 1) The viscosity changes by more than ±15%; 2) The acid value exceeds the standard; 3) The content of metal particles increases abnormally.

5. Maintenance suggestions

1.Create oil product file: Record the brand, model, quantity and usage time of each refueling.

2.Regular sampling and testing: Important equipment is recommended to take samples for laboratory analysis every 500 hours.

3.Storage precautions: Unopened oil should be stored in a cool, dry place away from direct sunlight. The shelf life is usually 2-3 years.

4.Waste oil treatment: Professional recycling is carried out in accordance with national environmental protection requirements, and random dumping is prohibited.

6. Future trends

According to industry trends, gear oil technology is developing in the following directions:

1.Long life formula: Develop synthetic gear oil with a service life of 8-10 years.

2.Intelligent monitoring: IoT sensors monitor oil status in real time to achieve accurate oil changes.

3.Environmentally friendly additives: Reduce heavy metal content and improve biodegradability.

The correct selection and use of gearbox lubricants can not only ensure efficient operation of equipment, but also significantly reduce maintenance costs. It is recommended that users choose appropriate oil products based on the equipment manufacturer's recommendations and actual working conditions, and establish a scientific maintenance plan.
