TIMKEN imperial tapered roller bearings are commonly used structure and performance

TIMKEN structure and performance of 2019 - inch tapered roller bearings commonly used 09 - TIMKEN 25 inch tapered roller bearing structure and assembly dimension accuracy and rotation accuracy is different from the metric bearing. Used for imports of machinery, or special needs of industry. Commonly used structure are: the single row circular cone roller bearings ( TS) , the single row tapered roller bearing outer ring flange ( TSF） Double row circular cone roller bearings, double inner circle ( TDO） Double row circular cone roller bearings, double outer race ( TDI） , double outer ring inner cone Kong Shuang row taper roller bearings, TDIT） Taper roller bearings, double inner ring ( TDI、TDIT、TNA、TNASW、TNASWE） , double row with baffle combination ( 党卫军,SR) With baffle double column combinations ( 2TS- IM、2TS- DM、2TS- TM） 。 1, single row tapered roller bearing type TS: this is a basic and the most widely used taper roller bearing type, consists of inner ring components and outer ring. The design of the tapered roller bearing has the special suitable for joint under load. Bearing axial load to bear ability depends on the size of the contact Angle ɑ, contact Angle, the greater the axial load capacity is higher. The size of the contact Angle can be represented by calculating coefficient e. The said value coefficient, the greater the contact Angle, the greater the bearing axial load capacity is higher. 2, single row tapered roller bearing outer ring flange TSF model: outer ring flange for axial positioning and precise alignment of the bearing seat mounting surface. And simplify the bearing configuration design and provide a more compact structure. 3, double inner ring type double row circular cone roller bearings TDO: bearing by an integral outer ring and two single inner ring. Usually supply along with an inner ring, ring, as a preset clearance component, this structure provides a larger bearing span effectively, and is often used on the overturning moment as the main load of the application. To be able to use in a fixed (TDO bearing Positioning) Position or allow floating within the bearing inner hole, such as come to compensate the expansion of the shaft, the outer ring with the hole on the outer diameter, allows the use of positioning pin to prevent outer ring spinning in the bearing seat. 4, double outer ring double row circular cone roller bearings TDI type: the bearing by a whole of inner ring and two single outer ring, usually along with an outer baffle supply. As the default clearance components, bearing can use in the application of fixed rotation axis ( Positioning) Place. 5 double row circular cone roller bearings, double outer ring TDIT type: the bearing inner hole for conical, must use the interference fitted which can be used, but often need to remove the applications. 6, double inner ring type double row circular cone roller bearings TNA: like TDO products, by an integral outer ring and two single inner ring. Two inner ring of the small end face is connected, do not need to separate the baffle. Bearing provides standard built-in clearance, can be used in a fixed or floating. 7, double inner ring type double row circular cone roller bearings TNASW and TNASWE: TNA product deformation, inside is on the small end face of chamfering and lubrication groove through the shaft of the bearing lubrication. TNASWE has widen the inner ring of big guard, a big guard of grinding can use seal or pressure plate. This kind of product can be used on the fixed shaft. 8, double row taper roller bearings with baffle equipping SS type: composed of two sets of single bearing piece together ( TS type) Equipping the preset clearance. SS type is often referred to as' snap ring combination, together with the inner ring and outer ring baffle. SS type with the specified clearance to adapt to the working condition of the scene of the set range, with a baffle and a snap ring ( Also used as the outer ring baffle) To give the through holes in the bearing axial positioning. 9, double row with baffle equipping tapered roller shaft SR type: made up by two sets of single bearing ( TS type) Assemble the preset clearance. Bearing with two baffle and an optional for axial positioning card ring. 10, pairing with baffle 2 ts - tapered roller bearing IM: this type of bearing is composed of two sets of single row circular cone roller bearings, with an inner ring and an outer circle, in some applications, the baffle is also by the bearing block of shoulder instead. We often say that matches back-to-back. 11, pairing with baffle 2 ts - tapered roller bearing DM type: this type of bearing is composed of two sets of single row circular cone roller bearings, inner ring two large end face, with a baffle, commonly used in the application of the fixed end on the rotation axis. Is often said that the pairs face to face. 12, pairing with baffle 2 ts - tapered roller bearing TM: this type of bearing is composed of two sets of single row circular cone roller bearings, two sets of single bearing series installation, to provide a proper inner ring and outer ring insulation, can bear larger axial force component of the single direction. Is often said that the series of matching, the matching pattern is not frequently used. Hk united bearing focus bearing industry informationization service nearly 20 years, with many excellent bearing enterprise grows together, also witnessed China's bearing production technology from low to high development process. We will adhere to continue, the steadfast work, don't, don't give up, for the benign development of Chinese bearing industry do render some. Hk united bearing network bearing engineers, 2019. 03. 25
