19. Install the front wheel and tighten the bolts in diagonal order. 20. The task of high-speed bearing lubrication must effectively deliver the lubricant to the moving surface in the bearing, repeat this process, and complete the maintenance on the other side. 21, use a jack to lift one side of the front wheel to remove the triangle iron bracket or pad brick, and the jack is unloaded so that the front and rear wheels hit the ground.

Repeat this process so that the front and rear wheels on the other side hit the ground. 22. Use a wrench to tighten the tire fixing bolts in diagonal order (should not be less than 40 kg torque). Illustrate; It takes about 2-3 hours for a single person to complete the maintenance.

Required, the method of wheel bearing maintenance:

1. The trolley wheel bearing is a maintenance-free bearing, but some can be maintained manually;

2. Bearing is an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body to be bright, reduce the friction coefficient during its movement, and ensure its rotation accuracy;

3. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, its radial size, vibration and noise clearance volts are larger, and the highest level is also higher;

4. The rolling bearing is generally composed of four parts: the outer ring, the inner ring, the socks carrying the rolling element and the cage. According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings.

Hello, Hawatt Bearing is glad for your question.

High-temperature bearing maintenance. 3 points of common technique fighting Li Hushu:

1.When the temperature of the high-temperature bearing is too high during operation, or when it emits harmful noise, it means that it may be damaged or there is an invasion of foreign objects, and the high-temperature bearing should be removed for cleaning and inspection, and when it is found that the steel ball or slide ring is cracked and damaged or the bearing is not changed after cleaning, the new high-temperature bearing must be replaced.

2.High-temperature bearings must be protected from dust and moisture intrusion during operation, and any impact on the inner or outer ring of the bearing is strictly prohibited.

3.The grease should be renewed after 2000-2500 hours of high-temperature bearing operation, but not less than once a year.

High-temperature bearings should be maintained and maintained in time, so that the base block can prolong the service life of high-temperature bearings.

On the question of whether the new bearing should be cleaned before use (installation), my principle is: the bearing produced by the regular manufacturer, as long as the original packaging (especially the plastic bag inside) is not damaged, shall not be cleaned, for the following reasons:

I have visited a number of well-known bearing factories in China, they have bearing assembly lines, the whole assembly line is in a dust-free operation state, the workshop is a dust-free workshop, the operator needs to go through a number of procedures such as dressing and vacuuming to strictly ensure the cleanliness of the workshop, and also has a workshop cleanliness (air suspended particles) automatic detection device. The whole assembly line is automatic, including ultrasonic cleaning, air drying, automatic assembly, testing, anti-rust oil injection, vacuum packaging, carton outer packaging, boxing, packaging and other complete operations. Therefore, as long as the inner packaging of the bearing that comes out of such an assembly line is not damaged, it should be very clean, and any on-site cleaning operation cannot achieve such cleanliness.

In most cases, the cleanliness of your environment is not up to the mark. For example, the container itself is not clean, and at the same time, the first cleaned bearing has sundries that are cleaned out in the cleaning liquid (generally kerosene, many people use gasoline on site), and the second is clean, but after cleaning, it is polluted, and impurities and sand enter the bearing raceway, which will directly affect the service life of the bearing.

If cleaning is necessary, then it is necessary to use standardized cleaning equipment with spraying, circulation, and filtration devices, otherwise it will only backfire.

It can not be cleaned, the bearing is shipped with lubricating oil, and it is cleaned several times before leaving the factory, and it is OK not to touch the dirt and water quality.

As an important mechanical accessory, bearings are widely used in living environments. An important indicator of bearing quality is the cleanliness of the bearing, which needs to be effectively cleaned during production and use to prolong its service life. The traditional method is to use kerosene spray or gasoline manual cleaning, but these methods have the defects of high cost, large labor demand, low efficiency, etc., and cannot meet the product cleanliness standard and the user's needs, so it is of practical significance to choose a safe, economical and efficient rolling bearing cleaning method.

Why should bearings be kept clean?

Pollutants, dust, debris produced by wear, alumina and silica and other small particles adsorbed on the surface of the rolling bearing without special protection, especially the lubricating surface, will form abrasive-like friction, causing serious wear on the contact part between the bearing rolling element and the raceway, and reducing the service life of the bearing under long-term wear. In addition to having a certain impact on the service life, the low cleanliness of rolling bearings will also seriously damage the components if there is particulate pollution in the bearing elements, resulting in vibration, noise, abnormal sound and other failures, and the serious probability of equipment accidents.

Why choose a bearing ultrasonic cleaner?

Ultrasonic cleaning is a new type of technology that has emerged in recent years, the principle is through cavitation, through the cavitation of ultrasonic conduction of cleaning agents, the deep holes, gaps, and hidden positions of the bearing can be effectively cleaned, and the use of bearing cleaning machine will not cause damage to the bearing surface. Because of the good cleaning effect and high efficiency, ultrasonic cleaning has been recognized by the majority of users, replacing the traditional cleaning method, and is widely used in rolling bearing cleaning.

In the actual industrial cleaning, the specific process of the ultrasonic cleaning machine and the supporting cleaning agent need to be based on the actual production situation and the number of batch cleaning, and the cleaning plan and cleaning process are formulated by professional ultrasonic technical engineers, so it is recommended to find some well-known enterprises in the industry and larger factories for consultation (such as Goodt Ultrasonic) to obtain the most suitable cleaning solution for themselves.

With the progress of bearing technology, people have more and more stringent requirements for bearing cleanliness and energy saving, and bearing cleanliness affects the service life and application effect of bearings. After comprehensively comparing the traditional cleaning methods, it is a good choice to choose to use the bearing ultrasonic cleaning machine to clean the bearing, which not only has better cleanliness and higher cleaning efficiency, which can not only effectively improve the service life of the bearing, but also benefit the environment.

1. In order to give full play to the bearing and maintain its due performance for a long time, it is necessary to do a good job in regular maintenance (regular inspection). It is important to detect faults at an early stage and prevent accidents before they occur through appropriate regular inspections to improve productivity and economy.

2. When cleaning and removing the bearing for inspection, first use photography and other methods to make a record of the appearance. In addition, check the amount of remaining lubricant and sample the lubricant before cleaning the bearing.

3. The cleaning of the bearing is divided into rough washing and fine washing, and the metal grid can be placed at the bottom of the container used.

4. During rough washing, use a brush to remove grease or sticky objects in the oil. In this case, if you rotate the bearing in oil, be careful that the rolling surface will be damaged due to foreign matter, etc.

5. When fine washing, slowly rotate the bearing in the oil, which must be carried out carefully.

6. The cleaning agent usually used is neutral and does not contain water, diesel or kerosene, and sometimes warm lye is used as needed. Regardless of the type of cleaning agent used, filter it frequently to keep it clean.

7. After cleaning, immediately coat the bearing with anti-rust oil or anti-rust grease.

8. In order to judge whether the removed bearing can be reused, it is necessary to focus on checking its dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage and sealing ring.

9. The inspection results can be judged by those who use inertial bearings or are proficient in bearings.

10. The criteria for judging vary according to the mechanical properties and importance, as well as the inspection cycle. If there is any of the following damages, the bearing shall not be reused and must be replaced.
