The key technology of Luoyang bearing

Design and Analysis: Analog design experience is still the main study stress analysis and load spectrum is almost blank. Technical difficulties which are the requirements for spindle bearings trouble-free operation of 13 * 104h or more, and have more than 95 percent reliability; Luoyang bearing gearbox bearings for high load capacity design a high failure rate and so on. Luoyang bearing Materials: different parts of the bearing using different materials and heat treatment, such as increased yaw and pitch bearings 40CrMo steel at low temperature (ambient temperature -40 ℃ ∽-30 ℃, the bearing operating temperature of about -20 ℃) ​​Cylindrical roller bearing and other mechanical impact energy heat treatment method performance control surface induction hardening of the hardened layer depth, surface hardness, soft bandwidth and surface cracks; gearbox bearing equivalent foreign STF, HTF steel research and control its optimum content of residual austenite research; Luoyang bearing spindle bearing quality steel in the domestic vacuum degassing surviving in the case of a gap, Taper bearing using ESR carburizing steel ZG20Cr2Ni4A manufacturing. Anti-corrosion and sealing. Yaw and pitch bearing special clearance requirements. Yaw and pitch bearing raceways grinding. Spindle bearings and gearbox bearings precision machining. Transmission bearings maintain improved design frame. Testing and so on.

Introduction and structural characteristics of Tapered roller bearings

  Tapered roller bearings can withstand axial load in one direction, a direction to limit the axial displacement of the shaft or housing. Tapered roller bearings are mainly used to bear radial load mainly radial and axial joint load. Compared with angular contact ball bearings, bearing capacity, low speed limits. Double row tapered roller bearing outer (or inner) as a whole. Two inner (or outer) face similar small, middle spacer, clearance by adjusting the thickness of the spacer, and can also be used to adjust the thickness of the spacer double row tapered roller bearings preloaded. Tapered roller bearings mainly bear radial diameter, axial joint load. Load bearing capacity Crossed Tapered Roller Bearing  on the angle of the outer ring raceway, the greater the bearing angle Carrying capacity greater. These bearings are separable bearings, according to the number of columns bearing rolling elements into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance to be user adjusted during installation. Tapered roller bearings have tapered inner and outer ring raceways, tapered rollers are arranged between the two. All conical surface projection lines are a little get together with the bearing axis. This design makes tapered roller bearings particularly tapered rollers  for the accommodation of combined (radial and axial) loads. Most of axial load bearing capacity is determined by the contact angle α; greater the α angle, the higher the axial load capacity. Tapered roller bearings are usually separated type, that is with roller and cage assembly of components of the inner cone and cone outer (outer) installed separately. Tapered roller bearings are separable bearings, inner and outer rings have tapered raceway. These bearings are loaded according to the number of columns roller into single row, double row and four row tapered roller bearings, such as different structural types. Single row tapered roller bearings can support radial load and axial load in one direction. When the bearing radial load, will produce an axial component, so when you need another can withstand axial force in the opposite direction of the bearing to be balanced.

Tapered roller bearings on the basis of components

According to the different nature of the friction of moving parts, the bearings can be divided into two types of rolling bearings and plain paired tapered bearing. China is one of the countries in the world earlier invention of rolling bearings, in ancient China, the structure has long been documented about the axle bearings. Seen from archaeological artifacts and data, China's oldest Rolling bearing structure with a modern prototype, appeared in BC Bearing is an important foundation for all types of Cylindrical roller bearing and equipment, spare parts, its precision, performance, longevity and reliability of the host precision, performance, longevity and reliability play a decisive role. Mechanical products, bearings are precision products requires not only a comprehensive support mathematics, theoretical physics and many other disciplines, but also materials science, heat treatment technology, precision machining and measurement technology, slim bearings technology and efficient numerical methods and powerful computer technology and many other disciplines to serve, so the bearing is also a representative of the national scientific and technological strength of the product.paired tapered bearing Is fixed and reduce part load coefficient of friction in mechanical transmission process. You can also say that when the other parts on the shaft relative motion to each other, the process used to reduce the power transmission coefficient of friction and keep the shaft center position fixed parts. Bearing is a kind of modern machinery and equipment vital components. Its main function is to support the mechanical rotating body to reduce the equipment in the transmission process, mechanical load coefficient of friction.
