In agricultural production, reliable agricultural machinery and equipment provide important guarantees for agricultural production. In the operation of agricultural machinery, damage to agricultural machinery parts is an important cause of agricultural machinery failure, which has a serious impact on agricultural production efficiency. Therefore, in current agricultural production, in-depth research on the causes of damage to agricultural machinery parts, taking effective measures to prevent damage, and improving the efficiency of agricultural machinery use have profound significance.

1. Common causes of damage to agricultural machinery components

(1) Damage caused by wear and tear

Wear and tear caused by friction of agricultural machinery in agricultural production, resulting in damage to agricultural machinery components, is quite common in current agricultural machinery use. In general, in the daily application of agricultural machinery, due to different working environments, various foreign objects such as dust, residue, weeds, etc. can cause wear and tear of the mechanical equipment. These foreign objects enter the agricultural machinery and affect the original precision mating surfaces and lubrication structures of the machinery. With long-term use, the cycle of agricultural machinery equipment deteriorates, causing key transmission components to lose their effectiveness prematurely. In addition, agricultural machinery similar to rotary tillers may come into contact with soil to some extent during actual operation. Due to substances such as sand, gravel, or stones in the soil, the agricultural machinery is severely worn down, such as the blades of rotary tillers, which are damaged by sand and gravel.

(2) Damage caused by materials and heat treatment processes

Incomplete materials or non-standard heat treatment processes are important factors causing damage to agricultural machinery parts. During the processing of parts, some of the materials have chemical compositions that do not meet the standards, and the processing of metal components is not standardized, resulting in problems such as cracks or wrinkles inside. Over time, this can lead to damage to agricultural machinery components. However, this issue cannot be visually detected during the process of purchasing and processing raw materials, which can easily lead to damage and failure of parts due to defects in raw materials during long-term use. If there are minor quality problems inside agricultural machinery parts, such as cracks, under normal use, the damage problem will not occur too early, so it will not have a significant impact on the functionality of agricultural machinery. However, if the metal structure undergoes heat treatment or welding, it will change and exacerbate crack problems, which has become an important cause of damage to agricultural machinery parts.

(3) Damage caused by design defects in parts

In agricultural production, the operating environment of mechanical equipment is complex, so strengthening the design of agricultural machinery parts requires sufficient consideration of the load or sealing of the parts, while also paying attention to the complexity of field operations to ensure their safety factor. In the daily operation of agricultural machinery equipment, the calculation of load safety factor is not high in the design of parts, and blockage occurs in agricultural machinery during field operations, which is the main manifestation of damage to most agricultural machinery parts. In this case, the load on agricultural machinery parts increases sharply, causing the parts to bend or break, or due to unreasonable design, foreign objects enter the sealed transmission box, resulting in damage to the sealed transmission parts of the closed gear transmission. In addition, due to unreasonable layout during the design process, the mechanical properties of the parts cannot be fully utilized, and the actual stress situation in operation does not meet the expected requirements, resulting in excessive local load force, cracks and bending of the parts, and serious consequences.

(4) Poor maintenance and damaged parts

In the daily use of agricultural machinery, paying attention to maintenance and upkeep is particularly crucial. In agricultural production, many drivers do not pay attention to the daily maintenance and upkeep of parts, which leads to problems such as loosening of agricultural machinery parts, insufficient lubricating oil, and even loosening of chains and belts. Over time, these problems gradually accumulate, resulting in the detachment and damage of agricultural machinery parts, which affects the service life of agricultural machinery.

2. Suggestions for preventing damage to agricultural machinery parts

(1) Lubrication is an effective method to alleviate part wear, and lubrication of parts can effectively reduce their wear. Lubricating the surface of the parts effectively reduces the friction between the surface of the parts and the external environment, thereby extending the service life of the parts. Therefore, in agricultural machinery maintenance, it is necessary to scientifically select lubrication methods based on actual conditions. Lubricating oil should be selected from regular manufacturers, and regular inspections of lubricating oil and grease should be carried out to check whether they are sufficient. If parts without lubrication show wear, targeted analysis should be conducted to determine whether the damage is caused by inadequate lubrication.

(2) Agricultural machinery manufacturers should pay attention to investigating the causes of agricultural machinery product failures and component damage. Based on annual after-sales service, they should collect and organize information on component damage caused by design and processing errors, analyze the causes of damage, take targeted measures, optimize design and processing, ensure the quality of agricultural machinery products, and promote the development of more mature agricultural machinery products.

(3) Agricultural machinery drivers also need to have a deep understanding of agricultural machinery maintenance, upkeep, and working principles to ensure correct and standardized operation. Before each operation, they should carefully inspect the agricultural machinery equipment to see the probability of risk occurrence. At the same time, they should regularly check the tightness of inspection parts and the tension effect of belt transmission, chain transmission, etc. They should pay attention to the agricultural machinery fault indicator lights. Once a problem occurs, they should immediately stop for inspection.

(4) Agricultural machinery maintenance institutions should continuously improve their technical capabilities, strengthen the technical training and evaluation of agricultural maintenance personnel, ensure the scientific and reasonable maintenance of damaged agricultural machinery parts, prevent the aggravation of agricultural machinery failure problems, and provide backup power for the maintenance of agricultural machinery and equipment. At the same time, advanced maintenance technologies and equipment should be introduced to create conditions for the improvement of agricultural machinery maintenance quality and efficiency.

In summary, with the rapid development of the social economy and the gradual improvement of agricultural machinery procurement policies, the level of economic development in rural areas continues to improve. As a result, the application of agricultural machinery and equipment continues to expand, improving the production efficiency of agriculture. In addition, in the actual use of agricultural machinery, the reliability and service life of agricultural equipment are highly valued by agricultural machinery operators, and many agricultural machinery failures often come from damage to agricultural machinery parts. For agricultural machinery parts, there are many ways of damage, which can lead to different causes of damage. Therefore, it is necessary to carefully analyze and organize the common causes of damage to agricultural machinery parts, analyze and summarize the root causes of part damage, take effective preventive measures and response methods, enhance the reliability of agricultural machinery equipment, extend the service life of agricultural machinery equipment, and ensure agricultural production efficiency.

Insert Bearings：

Insert bearings (SKF Y-bearings) are based on sealed deep groove ball bearings in the 62 and 63 series, but have a convex outer ring and in most cases an extended inner ring with a specific locking device, enabling quick and easy mounting onto the shaft.
