Precision bearings industry will usher in a new round of development opportunities

At present, China's secret bearing market environment is changing, industry development policy environment is changing, bearing manufacturers the previous government used to promote the development of the use of incentives, and now it is by comprehensively deepen reforms to seek a new impetus for economic development.

For the transformation and upgrading of enterprises, more accustomed to in the past, driven by administrative means, High speed Spindle but now more Forced by market forces.

Similarly, in the product technology and industrial scale, China's secret bearing industry has made great breakthrough. In the process of development of precision bearing industry, our market has been mainly adhere to the innovation and development, angular contact thrust ball bearing strengthen technical exchanges between the developed countries, greatly enhance the strength of precision bearings industry, enhance the market competitiveness of products. Public Wyatt emerged as precision bearings so influential at home and abroad in the precision bearings brand.

ZYS clutch bearing

When the clutch release bearing work, the clutch pedal force will be transmitted to the clutch release bearing. Clutch pressure plate clutch bearing toward the center,durability tester ,so that the pressure plate is pushed away from the clutch, the clutch plate and flywheel separation.

When the clutch pedal is released, before the spring pressure within the pressure plate pressure plate will push,Slewing bearing ,press the clutch, the clutch plate and clutch bearing separation, and the completion of a work cycle.

The basic model consists of a deep groove ball

The basic model consists of a deep groove ball angular contact ball bearing outer ring, an inner ring, a set of balls and a group holding structure into. Deep groove ball bearing type has two kinds of single and double row deep groove ball structure also points sealed and open two structures, open means without turbocharger bearings seal structure, sealed deep groove ball into the dust seal and oil seal. Dust sealing cap material is steel stamping.
When the only radial load, the contact angle is zero. When the deep groove ball bearings with a larger radial clearance, with angular contact bearings can bear large axial load, the friction coefficient is small deep groove ball bearings, the speed limit is also high.
Shielded deep groove ball High speed Spindle with rubber ring of deep groove ball bearings with snap groove deep groove ball bearings, have installed ball gap large load capacity of deep groove ball bearings, double row deep groove ball bearings.

High-speed motors have broad application prospects in the following areas:

High-speed motors have broad application prospects in the following areas:
(1) high-speed motor to be applied in a variety of occasions, air conditioner or refrigerator centrifugal compressor, etc., and with the development of science and technology, more and more specific requirements, its application will be more extensive.
(2) With the development of automotive hybrid cars, small size, light weight, high-speed generator will get full attention, and has a good prospect in the field of hybrid vehicles, aviation, shipbuilding and so on.
(3) high-speed gas turbine generator driven by a small volume, with high mobility, can be used in a number of important facilities, standby power, but also as an independent Bearing manufacturing machine supply or small power stations to make up for lack of centralized power, and has important practical value .

Common spindle bearings have grease lubrication

Common spindle bearings have grease lubrication, oil mist lubrication, oil lubrication, lubrication and ring jet lubrication and so on.
Grease lubrication without any equipment, lubrication method commonly used in low-speed spindle. dn value of the spindle at 1.0 × 106 or more, use more oil lubrication methods.
Oil mist lubrication is a lubricating oil (such as turbine oil) after pressure air atomizing for railway bearing lubrication. This way to achieve easy, simple equipment, oil mist lubrication function of both, but also play a role in cooling the bearing, but mist difficult recovery, serious environmental pollution, it is gradually being replaced by new oil and gas lubrication.
Oil lubrication is not a small amount of lubricant is atomized by compressed air directly timing, quantitative uniform bearing lubrication area was brought to a dedicated oil and gas pipelines along the wall. Lubricating oil lubrication role, and compressed air to propel the movement and cooling lubricants bearing role. Oil is always in the disengaged state, which facilitates oil recovery, while the environment is not polluted. The implementation of oil lubrication, generally requires that each has a separate oil and gas bearing nozzles to spray at the position of the Deep groove ball bearing, there are strict requirements, otherwise difficult to ensure lubrication, oil lubrication effect is also affected air traffic and oil and gas pressure. Generally speaking, the air flow can be increased to improve the cooling effect, and improve oil and gas pressure, not only can improve the cooling effect, but also contribute to the lubricating oil to reach the lubrication zone, and therefore, to improve the oil and gas pressure helps to improve the speed of the bearing.

Common spindle speed dn value

Common spindle speed dn value (dn value is the average diameter of the spindle radial clearance (mm) and the limit speed (r / min) the product of the spindle) to measure the speed spindle often refers to the value of the spindle dn 1.0 × 106 or more. With the development of bearing technology, lubrication technology, the spindle speed to improve year by year. The data show that in the 1980s, spindle bearing grease lubrication dn values ​​under conditions of maximum reach 0.5 × 106, but after the oil lubrication device developed, dn values ​​rapidly increased to 1.0 × 106, using angular contact ceramic ball bearings after, dn value of the spindle bearings further increased to 2.0 × 106.

High-speed machining technology more and more people's attention

High-speed fatigue testing machine technology more and more people's attention, it is not only for greater productivity, but also get high processing quality, and reduce production costs, and thus is considered to be the 21st century's most promising advanced manufacturing technology one.
In the advanced industrial countries, this technology has been widely used in aviation, aerospace and die industries. In the past five years, the technology of our country has made considerable progress. Is a prerequisite for high-speed cutting,
High-speed machine tools and virtual axis machine tools are groundbreaking major change. Whether ordinary or virtual axis CNC machine tools, a key component to achieve high-speed spindle unit remains.
