Automobile used engineering plastic sliding NSK bearings
NSK bearings used on engineering plastic sliding car on a lot of use of bearings are have special requirements, so the choice of auto bearing is not easy. Today I will to introduce to use the engineering plastic sliding off the bus, I hope it can help you choose.
The primary request of seat system is low cost
Usually used for seat system or stamping of sheet metal materials in the hole, and lengzha steel plate has a large size tolerance. However, in the seat system requires the smallest gap to minimize noise. In order to solve this contradiction, now more and more engineering plastic sliding bearing is used. Iglidur engineering plastic sliding bearing production and provide by igus company. The sliding bearing, if through the installation of flange rivet, in electrophoretic processing, through the automatic correction can compensation gap. Another way is to use clamp bearing to axial positioning, installed Yu Chongkong sheet.
Chassis: high bearing, high temperature resistant material
The stand or fall of automobile chassis performance directly affect the ride comfort and driving safety. Then must choose high load and high temperature resistant material. The material of high load, high temperature resistant iglidurz can in the high pressure of 150 mpa and 250 ℃ high temperature under the condition of normal operation. In addition, ensure the low elastic modulus of engineering plastics in shock or vibration, has the very good shock absorption performance.
Engineering plastic material used in transmission system
Auto transmission system for the low cost of engineering plastics materials provide a more broad application of space: from gear box and actuators to variable speed gear gear system. IglidurH4 material of sliding bearing to replace the traditional metal sliding bearing and rolling bearing. In practice, this material shows excellent shock absorption, at the same time can effectively and avoid contact with the surface of the cast aluminum matrix wear. In addition, the material resistant to oil, can be used under the temperature of 200 ℃.
Steering system: low coefficient of friction, high hardness
Nowadays, in the new car on the road without using engineering plastic sliding bearing. Steering system, for example: in the adjusting mechanism of steering column, low friction coefficient and high hardness is important - even if they don't consider stand larger machining tolerance. IglidurJ slotted sliding bearing materials. Its use can effectively compensate the gap, at the same time, guarantee has the similar kinetic friction coefficient and the static friction coefficient. In respect of steering shaft, igulidurF material under the condition of bearing in the lubrication state of installation, high pressure and low friction coefficient.
Butterfly: low coefficient of friction and wear
In butterfly valve, more and more use of engineering plastic bearing pressure into the plastic base. This design meet the needs of the structure compactness. IglidurH4 material of engineering plastic bearing, even in the used with PA or PPS material shaft, remain extremely low friction coefficient and wear volume. In addition, this kind of bearing has allowed for plastic coating processing.
The brake chuck bearing made of engineering plastic materials
Extreme vibration, corrosion, high temperature and high load - brake chuck in the bearing is used for under such harsh conditions. IglidurH2 / H4 material, has excellent bending resistance and abrasion resistance. Under this condition, can achieve surprising long service life. The wear resistance of particles is through its material into reinforcing fiber.
"More economic use of engineering plastic sliding bearing,"
In addition to the excellent mechanical properties and lubrication, and the advantages of the dry run, price of engineering plastic sliding bearing is quite low. It is also the material is widely used in automobile manufacture is an important factor.
