Calculation and analysis of high-speed precision spindle bearing thermal properties
2015-11-27
Bearing frictional torque, the higher the speed, the frictional heat generated by the more, the higher the temperature rise of the bearing, the bearing for the high speed bearing (dn values in the range of 2,000,000) the use of oil-air lubrication can be well suppressed bearings the temperature rise.

Bearing frictional torque, the higher the speed, the frictional heat generated by the more, the higher the temperature rise of the bearing, the bearing for the high speed bearing (dn values in the range of 2,000,000) the use of oil-air lubrication can be well suppressed bearings the temperature rise. For the friction torque and friction heat precision spindle bearings, the greater torque, bearing fever mainly related with the friction torque. Frictional heat generated by the more. According to the formula derived Palmgren, the bearing friction torque has two parts: frictional torque occurring lubricant viscosity and friction torque and speed independent of load occurs.

A number of incidents have occurred recently involving failure of the slew bearings of ships’ cargo deck crane bearing, resulting in crane losses and serious injury to personnel. These failures have been caused by undetected excessive wear in the slew bearings.Rocking tests Crane manufacturers generally recommend that ‘rocking tests’ are carried out every six months in accordance with their instructions, and that the results are recorded and monitored in order to ensure the wear tolerances remain within the limits permitted by the designers.Cranes which are particularly at risk are those with single ball race slew bearings. Cranes fitted with this type of slew bearing must have rocking tests carried out, in accordance with manufacturer’s instructions, to determine that the amount of wear in the bearing races is within permitted limits.

truck mounted crane bearing fall rolling sound
2015-07-20
The noise in general, mostly large truck mounted crane bearing at low speeds and bear radial load. When the operation of the bearing in the radial load, load and non load bearing, if the truck mounted crane bearing has a radial clearance, the non load area of the rolling body and the inner raceway no contact, but because of the action of centrifuga... The noise in general, mostly large truck mounted crane bearing at low speeds and bear radial load. When the operation of the bearing in the radial load, load and non load bearing, if the truck mounted crane bearing has a radial clearance, the non load area of the rolling body and the inner raceway no contact, but because of the action of centrifugal force may be associated with the outer ring contact, therefore, at low speeds, the centrifugal force is less than when rolling body weight when the natural vibration and noise, the rolling of the fall and and inner raceway or cage collision and motivate the bearing, and has the following characteristics:Easy to produce A. triple row roller slewing bearing grease lubrication, oil lubrication is not easy to produce. When use inferior lubricating grease are more susceptible to.B. often occurred in winter.C. for only the radial load and the radial clearance is large but also easy to produce.D. also can be in a certain range and different size bearing its speed range are also different.E. may be a continuous sound may be intermittent sound.F. the forced vibration often excited outer two order, three order bending vibration, thus make the noise. Through the use of pre load equation method can effectively reduce the noise, reduce the installed bearing radial clearance, choose good lubricants can also improve, some foreign enterprises adopt light rolling body, such as ceramic roller or hollow roller and other technical measures to prevent the occurrence of such noise.

Radial ball bearing is a universal design that can withstand the load of different sizes in the high-speed movement. This thin wall bearings type of rolling bearings by sets of precision ball and cage as well as the composition of the inner and outer rings. Which standard radial ball bearings there is a deep groove structure that can withstand the radial load and smaller axial load from any direction. Has a maximum load capacity of radial ball bearings mainly take radial load. This type of bearing a variety of sizes to choose from. Different configurations can be sealed to protect the internal components of rolling bearings and grease can be Needle Roller Bearing retained. Radial ball bearings are widely used in general industry, automotive industry, agriculture, chemical and household appliances industries. View Details

Deep groove ball bearings are precision parts, thus requiring the use of fairly cautious attitude that change is the use of high-performance bearings, if used improperly, they can not achieve the expected performance results, and easy to bearing damage.

Deep groove ball bearings are precision parts, thus requiring the use of fairly cautious attitude that change is the use of high-performance bearings, if used improperly, they can not achieve the expected performance results, and easy to bearing damage. Therefore, the use of bearings should note the following:First, the bearing and the truck mounted crane bearing surrounding environment be kept clean, even invisible dust into the bearing smile, will increase wear, vibration and noise of the bearings.Second, when using the installation to be carefully, do not allow a strong punch, does not allow a direct hit with a hammer bearing, are not allowed to pass through the rolling pressure.Third, the use of appropriate and accurate installation tools, to make use of special tools, try to avoid the use of fabric ship loader bearing and staple fiber stuff like that.Fourth, to prevent corrosion of truck mounted crane bearings, direct hands when handling bearings, to fully wash hands sweat, and coated with high-quality mineral oil before operation, especially during the rainy season and summer to pay attention to rust. However, under a particular operating condition, the bearing can get a longer conventionalLife calculation, especially in the case under light load. These particular operating condition is, when the rolling surface (track and rolling elements) and the limit Thrust Roller Bearings is effectively separated contaminants may cause damage to the surface of a lubricant film. In fact, under ideal conditions, the so-called permanent bearing Life is possible. View Details
