SULLI: I will introduce the rubber bearing in detail today. The rubber bearing in the water is mainly used for vertical bearing pumps and mixed flow pumps. Rubber bearing is used to support between shafts and axes. Copper rubber bearing, iron shell rubber bearings, bearing strips and full rubber bearings. Made by molding method. It is mainly used for ship axis flow pumps, deep well pumps, etc., as a supporting body of the slurry and pump leaves.

The rubber bearing in the water is mainly used for vertical shaft flow pumps and mixed flow pumps. It is especially suitable for circulating water pumps, washing pumps, cooling water pumps, seawater pumps, and drainage pumps of atomic energy stations and thermal power stations. On the other hand, due to the problem of water pollution caused by oil leakage in the oil lubrication beaches, the water lubrication method has been highly valued. The rubber bearing is also widely used in the ends of the stern axis, the rudder shaft, and the muddy cutter cut head -cut head shaft bearings Essence Rubber bearing is generally in machinery, and its main role is to support the effect of reducing friction first. Therefore, the accuracy, noise, etc. of the bearing are directly related to the use and life of machinery.

Rubber bearing function

Rubber bearing is used to support between shafts and axes. Copper rubber bearing, iron shell rubber bearings, bearing strips and full rubber bearings. Made by molding method. It is mainly used for ship axis flow pumps, deep well pumps, etc., as a supporting body of the slurry and pump leaves.

Advantages of rubber bearing

1. Little power loss

The sliding friction of wet rubber and metal is very small. The special rubber formula developed by our company makes the friction coefficient of the bearings smaller. Comparison of friction coefficient

2. Lear

Lignum vitae (material of wooden pulley and wood bearing) is more resistant to rubbing. It must be replaced in a few months in the use of a few months. If you use rubber bearing for more than 4 years.

3. It is not easy to damage axis and axis sleeve

Even between the sediment and the small stones entering the shaft and the rubber bearing, due to the effect of lubricating water, the rotating rotating cashmere bearing groove of the shaft is excluded. In order to make full use of this feature, our company made a special study on the rubber formula.

4. Anti -sound shock absorption

Due to the small friction between rubber bearings and shafts, the anti -sound reduction effect of rubber is obvious.

5. No pollution pollution

Because the lubricating material is water and no lubricating oil is required, no oil pollution is incurred.

Rubber bearing selection method

1. Selection of bearing models

The model of general bearing needs to be selected through some related technical professionals, and then the bearing is selected based on the main points of product use and the load it it bear. The business personnel mainly understand whether the actual load of the user is consistent with the selected bearing. If the bearing does not meet the requirements of the use, the customer should be recommended to make the model as soon as possible, but there is generally no problem in the selection model unless special products are selected.

2. Selection of bearing gap

When consumers are purchasing bearings, they will only provide models and grades to merchants. Few people will ask for the choice of bearing clearance. The business personnel must ask the use conditions of the bearing, the speed, temperature, and the tolerance of the bearing, and the tolerance of the bearing are directly related to the choice of the bearing gap. The choice of oil is generally based on the speed, temperature resistance, noise requirements, and starting power of the bearing. It is required that business personnel are required to know the performance of various oils.

3. The choice of bearing seal type

In terms of bearing lubrication, it is divided into two types, one is oil lubrication, and the other is fat lubrication. Generally, the oil lubrication bearing is selected for form bearing. The fat lubrication bearing is generally used. Seal the seal. The dust cover is suitable for high temperature or good environment. The sealing parts are divided into contact sealing and non -contact sealing. The contact -type sealing dustproof performance is good, but the power torque is large. There is no contact type.
