- Double row tapered roller bearings
Double row tapered roller bearings can only bear radial load at the same time it can be
subject to bi-directional load. It can be in bearing axial clearance range limit shaft or shell
two-way axial movement.
★Product features
The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surfaces of the
raceways and the roller axes if projected, would all meet at a common point on the main axis of the bearing. The rollers are guided by a
flange on the inner ring. This stops the rollers from sliding out at high speed due to their momentum. The larger the half angles of these
cones the larger the axial force that the bearing can sustain.
★Product application
In many applications tapered roller bearings are used in back-to-back pairs so that axial
forces can be supported equally in either direction.
Pairs of tapered roller bearings are used in:
- car and vehicle wheel
- mining equipment
- moderate speed
- engine motors
- axle systems
- construction
- agriculture
- reducers
- gear box
★Horton tapered roller bearings Basic size
- Single row tapered roller bearings:
Inner ring size: 20mm ~ 1270mm Outer ring size: 40mm ~ 1460mm Width size: 15mm ~ 240mm
- Double row tapered roller bearings:
Inner ring size: 38mm ~ 1560mm Outer ring size: 70mm ~ 1800mm Width size: 50mm ~ 460mm
- Four row tapered roller bearings:
Inner ring size: 130mm ~ 1600mm Outer ring size: 200mm ~ 2000mm Width size: 510mm ~ 1150mm
★Tolerance:
Horton tapered roller bearing with common
tolerance, and also provides P6X, P6, P5, P4,
★Radial clearance
Horton single row tapered roller bearings only
in after installation have clearance, and in
★Cage
Tapered roller bearing general ues the steel plate stamping, basket shape cage, but when the size is bigger, we
also adopts entity cage.
1. Outside diameter D ≤ 650mm, use the steel plate stamping cage, cage postposition without code mark.
2. Outside diameter D > 650 mm, use the steel entity prop cage, cage postposition without code mark.
★Dynamic equivalent load
P = Fr [KN], Fa / Fr ≤ e;
P = 0.4Fr + YFa [KN], Fa / Fr > e.
The single row tapered roller bearings used in pairs (basic physical size can be different), when calculation the
equivalent dynamic load of the bearing, must be included in the radial load cause additional axial force. The single
row tapered roller bearing additional axial force S, can approximate formula: S = Fr / 2y
★Static equivalent load
Single row tapered roller bearings
P0 = 0.5Fr + Y0Fa [KN] P0 < Fr, then P0 = Fr
Double row tapered roller bearings
P = 0Fr + Y1Fa [KN],Fa/Fre ≤ｅ P = 0.67Fr + Y2Fa [KN], Fa/Fre > e
- Q: Taper roller bearings are used on my motor. Serious damage occurred during use. Please help me analyze the possible causes of damage! Thank you
- To LZ: 1 it is recommended that the radial force and the rated load of the bearing be compared to determine whether the radial force is too large (if there is axial force, it needs to be synthesized as equivalent load, and then compare.) In 2 section, you basically is the middle of the two row tapered bearing ring and then as a double row tapered to use (not in general, so natural clearance installed back to back) without gasket or nut to adjust, this is a very good idea.
- Q: What is the size of tapered roller bearings 352214?
- Bearing type: tapered roller bearingNew model: 352214Old model: 97514EInternal diameter (mm):70Outside diameter (mm):125Width (mm):75
- Q: What are the conditions for the normal and reverse loading of tapered roller bearings?
- 2. anti loaded (outer ring width relative end) horns contact ball bearing or tapered roller bearing pressure center distance is greater than two at the midpoint of the bearing span, known as anti loading, obviously, axial thermal expansion will increase the axial clearance of bearing. In addition, the structure of reverse loading is more complicated, and it is inconvenient to assemble, disassemble and adjust.Stiffness analysis of positive and negative when the transmission parts of cantilever installation, shaft reverse mounting stiffness ratio of forward shafting high, this is because the distance from the center of pressure bearing with large, maximum bending moment of the bearing force, deformation and axial deformation and are less formal.
- Q: The roller of tapered roller bearings is cylindrical or cylindrical body? Why roller drawing method of drawing section for the rectangular (here I want to add: I have seen the N version, some of the paintings is rectangular, trapezoidal and some paintings, 2 versions, a few of my book is that the proportion is A/2 the roller projection) it indicates that the real roller should be a cylinder or a cylindrical body roller is... What master?
- Roller tapered roller bearing is a conical body, sometimes drawing simplified painted section cylinder, not misleading (a type of list), is also permitted.-- -- -- -- --
- Q: Tapered roller bearing: Bearing expert why burned or locked
- 1, improper choice of bearing clearance.For example: C3 group should be selected for clearance, and the actual use of ordinary group clearance. Because when the bearings work will continue to accumulate heat, shaft diameter and inner ring and outer ring rolling body will swell, because good radiating condition of expansion is relatively small, the whole bearing clearance becomes small, or even negative clearance larger.At this time, stress increases between the body and the rolling roller pressure, lubrication conditions decreased, there will be the phenomenon of boundary lubrication or even local steel on steel friction, so the temperature continues to rise, the base oil in lubricating grease evaporation, so lead to vicious spiral bearing overheating burned, rolling annealing into blue black color, then bearing the friction increasing roller holder to stop COLLOPSE bearing lock.
- Q: Tapered roller bearings. Are the rollers tapered?
- The cone can be seen as a right angled triangle revolving around a right angle, with a point at the top.
- Q: Can tapered roller bearings be installed in a vertical direction? In a vertical direction rather than in a horizontal direction..
- Absolutely. The bearing below the figure is the tapered roller bearing placed vertically.
- Q: The device is a vertical axis vertically arranged in the bearing chamber, the upper shaft without suspension, supported by bearings, shaft bearings are installed at the bottom of the outdoor rotating parts weighing 50 kg, the two ends of the shaft are used in single row tapered roller bearings, the bearings between the length of 30 meters. The rotation speed of the shaft is 480r/min. The device is suspended on a rotating turntable and is subjected to centrifugal force during operation...
- Why not such a large selection of axial thrust bearing, if the radial force selected contact angle greater than 45 degrees (thrust) tapered roller bearings or spherical roller bearings are good, ordinary radial cone bearing axial force mainly depends on the inner ring rib, movement and rib roller end surface contact of gyro rotation, life too effect of axial force, and excessive axial force will make rib fracture.
- Q: Tapered roller bearing suffix code YA2 stands for what does that mean?
- SatisfyHappiness is merely material meet? Of course not, happiness is not simple and get food and drink happy nor personal desires superficial meet. Wealth has sometimes not happy, luxury, and happiness cannot lead a gay life equate. Therefore, the material does not meet the real happiness.It is the balance of happiness tends to meet the spirit of Confucius, "there are friends from afar" or "awfully";
