Constant Velocity Joint Boot

-
Image
constant velocity joint ( CVJ) is an essential Part of the vehicle driven shaft system, supplying power to the wheeler. The wheels of an Automobile are rotated by the power of an engine transmitted through a rotating shaft, components of the shaft are coupled by a mechanism called Constant Velocity Joint which is required to transmit a constant rotation to the wheels. The types of CV  by position are inboard and outboard, by function are fixed or plunging and by design are ball type and tripod.  In front-wheel drive cars, ball-type CV joints are used on the outer side of the drive shafts (outer CV joints), while the tripod-type CV joints mostly used on the inner side (inner CV joints).  Inner CV joints connect the drive shafts to the transmission, while the outer CV joints connect the drive shafts to the wheels. In the vehicle,CV joints connect the transmission to the half shafts, and again from the half shafts to the wheels. These joints accommodate the up a

X SECTION RING

-
Image
X  SECTION RING S eals that approximate to an X section are manufactured as an alternative to O-rings. The cross-section may vary from something approaching a square section with lobes,  X-rings offer some potential benefits for certain applications. There are two indi-vidual sealing surfaces, so minor damage is less likely to lead to leakage. The cross-section is more resistant to spiral twisting with cyclic pressure. The mould parting line is not on the sealing surface of radial sealing applications, as it is with an O-ring. Of particular interest is that the elastomer interference is achieved by a combination of squeeze and deflection of the seal section.  would be acceptable for O-rings. However, because of the more compliant cross-section the pressure range is more limited. Depending on the actual cross-sectional geometry it may be limited to pressures in the range of 8–10 bar. Although they are more resistant to rolling than O-rings,

RECTANGULAR SECTION RINGS

-
Image
RECTANGULAR SECTION RINGS Rectangular section rings are widely used. They can generally be considered to be interchangeable with elastomer O-rings. They may be manufactured by moulding for high volumes but are also lathe cut from extruded tube. A particular benefit ofrectangular rings is that they will not flex under cyclic pressure. They will therefore be less prone to leakage due to flexing and wear,  For this reason theyare used as an alternative to O-rings on some high duty hydraulic equipment and similar applications. Another familiar application is oil filters on automotive engines,where improved stability during fitting is an important consideration. The rings may be of rectangular or square cross-section, depending on the application and manufacturing methods. O RING AND RECTANGULAR RINGS 1. Without  compression 2. With Compression 3.With Compression and pressure activated. 사각형 단면 링이 널리 사용됩니다. 그들은 일반적으로 엘라스토머 O- 링과 호환 가능. 이들은 성형에 의해 제조 될 수있다. 높은 볼륨

High pressure hydraulic hose

High Pressure Hydraulic hose In  recent years hydraulic has grown steadily and this trends is likely to continue well into the next century. The technological demands made on hydraulic hose manufactures have also increased and will intensify further in parallel  with market requirements for high pressure hoses. Pressure levels available for high pressure hoses have increased inordinately with improved design and the wire industry has provided a higher strength product to give designer the necessary material to facilitate these advances. Larger diameter wires with very high tensile strengths are now available which have the processing characteristics necessary for hose manufacture. Aramid textile fiber has also played a significant role in allowing the production of higher  pressure hoses particularly for the offshore oil industy. Hoses have become slimmer in wall, lighter in weight and more flexible thus they are able to work at lower bend radii and with capability

Hoses and its processing

-
Image
                                                                   Hoses: Most hoses are made up of three elements: (1) a tube, (2) reinforcement, and (3) an outer cover. 1.   Tube 2. Reinforcement 3. Outer cover Each of these components is usually adhered to the adjacent component by the bonding agents or thin layer of specially designed rubber. Tube: The tube is the inner most rubber or plastic element of the hose.The   tube may be placed over reinforcing elements. For suitable serive, the tube must be resistant to the materials it is intended to convey. The Characteristics of the rubber or plastic compound from which the   tube is made and the thickness of the tube are based on the service for which the hose is designed. Reinforcement: Reinforcement can be textile, plastic or metal alone or in combination, built into the body of the hose to withstand internal pressures, external forces or a combination of both .The type and amount of rein
