YOCH Bearing

The belt is too tight or the coupling is poorly assembled and in a bad state. Here you can adjust the belt tension and calibrate the coupling for repair.

Rolling INA bearings are classified according to the type and number of rows of rolling elements, the direction of the load they can bear, and whether they have automatic self-aligning function.

At the friction points between the crankshaft and the bearings, the crosshead and the slide plate, the packing and the piston rod, etc., the temperature exceeding the specified value is called overheating. The consequences of overheating: one is to accelerate the wear between the friction pairs, and the other is that the heat of the overheating continues to accumulate until the friction surface is burned and the lock is burned, causing major machine accidents. The main causes of bearing overheating are: uneven fit between the bearing and the journal or too small contact area; deflection of the bearing, bending and twisting of the crankshaft; too low viscosity of the lubricating oil, blockage of the oil circuit, failure of the oil pump, etc.; during installation There is no leveling, no clearance is found, the main shaft and motor shaft are not aligned, the two axes are tilted, etc.

During the operation of the compressor, some malfunctions and even accidents will inevitably occur. A fault refers to an abnormal situation that occurs during the operation of the compressor. Once eliminated, the compressor can resume normal operation, while an accident refers to a damage situation. The two are often related, and if a fault is not eliminated in time, it will cause a major accident.      Compressor is a machine used to increase gas pressure and transport gas. From an energy point of view, a compressor is a machine that converts the power energy of the prime mover into gas pressure energy. With the development of science and technology, the application of pressure energy has become increasingly widespread, making compressors one of the indispensable key equipment in many sectors of the national economy. During the operation of the compressor, some malfunctions and even accidents will inevitably occur. A fault refers to an abnormal situation that occurs during the operation of the compressor. Once eliminated, the compressor can resume normal operation, while an accident refers to a situation of damage. The two are often related, and if a fault is not eliminated in time, it will cause a major accident.

During the use of the machine, some noise will be generated more or less. Some of it is unavoidable, but some noise must be solved immediately once it is generated, otherwise it will affect the operation of the machine, make the production unable to operate normally, and cause unnecessary losses.

Welcome to our comprehensive guide on the advantages of utilizing precision needle roller bearings in industrial applications. In this article, we will delve into the various benefits that these bearings offer and how they can positively impact your operations. From their exceptional durability to their ability to handle heavy loads, precision needle roller bearings have become a vital component in numerous industries.

When the pipes of the brake system are filled with steam and gas exists, due to the relatively high compressibility of the gas, and the brake pedal feels soft and elastic when you step on it, it means that air has penetrated into the brake fluid. The braking effect will become worse, safety will be reduced, and the braking response speed will be reduced. Especially in mountains and mountainous areas, frequent braking will increase the temperature of the brake fluid. If the boiling point of the brake fluid is low, it is easier to cause cavitation in the braking system and damage the rubber sealing ring and brake components of the afterburner pump. cause damage. This will cause the braking system to completely fail and endanger personal safety. In addition, when there is gas in the brake fluid pipeline of the brake system, when the brake pedal is released, because the expansion speed of the gas is faster than the speed of the brake fluid, sometimes a flow from the brake oil cup of the booster cylinder to the brake fluid cup will occur. The phenomenon of external oil spraying. Brake fluid with a low boiling point seriously affects the braking performance of wheel loaders. At present, most domestic wheel loaders use 719 synthetic brake fluid, which is equivalent to HZY3 of domestic GB12981-2003 and DOT3 of the international standard. The dry boiling point of this brake fluid is 205°C. The dry boiling point refers to the fluid just removed from the sealed container. The boiling point of some inferior brake fluids is lower after being added to the brake system, and some inferior brake fluids have lower dry boiling points, thus affecting braking safety.

In recent years, loader brake system failures have become an increasing trend, especially brake failure, brake system temperature rise, oil leakage from the brake pump vent, and a series of other problems. At present, almost all domestic loader service brake systems use pneumatic brake systems. Top oil caliper disc brake, the selection of brake components is generally the same as that of automobiles. There are many factors that cause the failure of the loader's braking system, such as damage to the braking components leading to braking failure. In recent years, loader braking systems have become the main factor in the upward trend. The author believes that the decline in the quality of brake fluid and brake pads is also an influencing factor. The following is a brief introduction to the effect of brake fluid on the braking performance of wheel loaders.

Tapered roller bearings are separable, and their inner ring roller cage assembly and outer ring can be separated and assembled separately. Corrected linear contact between rolling elements and raceways avoids edge stresses. Tapered roller bearings can support both high radial and axial loads. Because this type of bearing can only bear axial force on one side, it needs to be paired when used. This type of bearing is used in gear boxes and axle holding boxes.
