Clearance is an important factor in rolling bearing can work normally, divided into the axial clearance and the radial clearance. Select the appropriate clearance, can make the load in the bearing rolling body between the reasonable distribution; can limit axis (or shell) of the axial and radial displacement, ensure the rotating precision linear plain bearings of shaft; the bearing work at a prescribed temperature; reduce the noise and vibration, to improve the bearing life. Therefore. In the selection of conical bearings, bearing clearance, must choose the appropriate.Selection of bearing clearance, should consider the following aspects:1, the bearing working conditions, such as load, temperature, speed etc.;2, on the use of performance requirements (bearing rotation accuracy, friction torque, vibration, noise);3, the bearing and the shaft and housing bore is in interference fit with the lead to reduction of bearing clearance;4, when the inner and outer rings of bearing, the temperature difference caused reduction of bearing clearance;5, because the expansion coefficient of shaft and housing materials of different, resulting in the decrease or increase of bearing clearance.6, according to experience, the most suitable for ball bearing clearance work to nearly zero; roller bearing should keep a small amount of mobile crane bearing clearance. At the request of supporting rigid good parts, bearing preload has certain value. Here is particularly pointed out that, the so-called clearance refers to the bearing clearance, in the actual operating condition. There is also a play called the original clearance, refers to the bearing without clearance. The original clearance than installation clearance. We choose to play, mainly is to choose appropriate clearance. View Details
conical bearing temperature are the main reason

The bearing temperature are the main reason:The first: whether the lubricating oil quality deterioration?

The bearing temperature are the main reason:The first: whether the lubricating oil quality deterioration? If the viscosity of lubricating oil can also result in INA bearing temperature riseSecond: bearing assembly if too tight, the gap will lead to inadequate flange bearing temperature rise;Third: bearing assembly worm gear speed reducer too tight will result in bearing temperature rise;Fourth: Race rotation on the shaft or shell will result in bearing temperature rise;Fifth: the bearing load is too large will result in bearing temperature rise;Sixth: if the conical bearing cage or a rolling body broken words, will result in bearing temperature rise.The amount of axial movement of the mobile or. According to the movement direction, can be divided into radial clearance and axial clearance. On the measurement of bearing clearance in the interior, in order to make the measurement value is stable, general test load was applied in the ring. Therefore, the test value than the actual clearance value, namely one more test applied load and elastic deformation. Bearing clearance operation, because the bearing with inner and outer rings and cause temperature, than the initial clearance of small. Running clearance and the bearing life, Wen Sheng, vibration and noise are closely related, so it must be set to the best state. Needle Roller Bearing Turntable bearings theoretically, bearing in operation, with negative clearance operation, the maximum bearing life. But it is very difficult to maintain the best clearance. With the change of the conditions of use, the negative clearance of bearings will increase, leading to the bearing life is significantly reduced or have a fever. Therefore, the initial clearance of bearings is slightly greater than zero. View Details

Under normal circumstances, the limit of 0.2 times the speed of the most desirable.2, using the site: combined load of tapered roller bearings for radial and axial radial load to bear mainly on, usually with two sets of angular contact deck crane bearing are used, primarily in the car front and rear wheel, a driving bevel gear, gear, reducer and other transmission parts.3, allow the tilt angle: tapered roller bearings are generally not allowed to tilt axis relative shell hole, such as tilt, less than 2'.4, allow the temperature: under normal load, and the lubricant has the advantages of high temperature resistance performance, and full lubrication conditions, allowed to work in -30 ℃ -150 ℃ temperature generally angular contact ball bearing.

This kind of bearing is separable bearings, roller bearings according to the number of rows into a single row, double row and four row tapered roller bearing. Single row tapered roller bearing clearance required user adjustment when in installation; double row and four row tapered roller bearing clearance has been in the factory according to user requirements given, the user does not have to adjust. Tapered roller bearings with tapered inner and outer ring raceway, tapered roller are arranged in between. All lines of conical surface projection at the same meet the bearing axis. This design makes the tapered roller bearings are particularly suitable to withstand complex (radial and axial load). Axial load bearing capacity is largely determined by the contact angle; alpha angle is larger, the axial load capacity is higher. Angle by calculating coefficients of e to say; the bigger the E value, the larger the contact angle, the axial load is bigger. Tapered roller bearings are usually separated type, namely the cone assembly with roller and cage assembly composed of conical outer ring and inner ring can be installed separately (outer ring). Tapered roller bearings are widely used in automotive, rolling mill, mine, metallurgy, plastics machinery industry. View Details
