Depending on the location and conditions of use and environmental conditions select size, precision is guaranteed with suitable bearing TIMKEN bearing life and feasibility of the premise.
1, using the site: tapered roller bearings for radial load mainly radial and axial joint load, usually paired with two sets of bearings, mainly in the automotive front and rear wheels, active bevel gears, differential device, reducer and other transmission parts.
2, the permissible speed: installed correctly, oiled environment, allowing for the TIMKEN bearings 0.3-0.5 times the speed limit. Under normal circumstances, at 0.2 times the speed limit is most appropriate.
3, allowing the tilt angle: Tapered roller bearings are generally not allowed axis relative to shell hole, if inclined, the maximum does not exceed 2 '.
4, allowing the temperature: the under normal load, and lubricant temperature performance, and full lubrication conditions, the general bearings allow the environment of -30 ℃ -150 ℃ temperature.
Removal and installation of rolling bearings should be carefully carried out the same time. Careful not to damage bearings and various parts, especially the demolition of an interference fit bearings, the operation is difficult. Therefore, at the design stage to take into account in advance for easy removal, according to the need to design the removal tool is also very important. In the demolition, according to the drawings of demolition methods, in order to investigate the rolling bearing with conditions to obtain the demolition job foolproof.
Removing the interference fit of the outer ring, the circumference of the housing in advance several outer extrusion screw is provided with a screw, the screw tightened equally side, while the removal. These usually cover the screw holes blind plugs, tapered roller bearings and other separation-type bearings, the housing block set shoulders several incisions, the use of pads, with press dismantling, demolition, or gently pounding.
Removal of the inner ring can be used to pull the latest simple mechanical pressure. At this time, pay attention to your inner bear its pullout.
Large bearing inner ring removal by hydraulic method. By setting the hydraulic pressure to the shaft hole, to make easy to pull. Width of rolling bearings is the hydraulic method and drawing fixtures and use, disassembly operations.
Removal more compact TIMKEN bearings with adapter sleeve, with shaft stopper secured support inner ring, the nut back several times, using the pads with a hammer and beat demolished.
Large bearings, the use of hydraulic demolition easier, in the cone axis pressurized oil feed hole, so that the inner expansion, demolition rolling method. Operation, there is the possibility of rolling suddenly emerge, it is best to use the nut as well as a stopper.
TIMKEN bearings after installation, in order to check for proper installation, operation should be checked. Small machines can be rotated by hand to verify rotate smoothly. Check the project due to nick, indentation caused by dysfunctional, because poor installation, mount the torque generated by poor processing unstable, because clearance is too small, the installation error, seal friction torque caused by too large and so on. Without exception, you can begin powering.
Consistency of grease and lubricating ability is affected by the operating temperature of a temperature of rolling bearings must operate at the same temperature to select the correct consistency and good grease lubrication. Fat in a different temperature range to produce a substantially low temperature can be divided into, and the high temperature with the temperature of the grease. Meanwhile, the main distinction according to the temperature and working conditions: oil according to its permissible operating temperature classification. There is a class of fats known resistance to crushing or resistance to crushing and adding molybdenum disulfide, and wherein lubricant with additives to enhance the strength of the film.
Through a variety of heat treatment, chemical treatment and the surface hardening treatment, can improve the bearing strength and wear resistance. Especially steel, and only after the heat treatment in order to fully display its superior mechanical properties. Alloy steel bearing stress concentration sensitivity is high, so the shape of the structure steel shaft must be reasonable, otherwise we lose the meaning of alloy steel.
Equipped with ABS unit has a seal bearing magnetic thrust ring, thrust ring can not be such a collision, impact or collision with other magnetic fields. Before installation remove from the box, so that they stay away from magnetic fields, such as the use of electric motors or electric tools. These bearings are mounted, through the observation of the dashboard road test needle ABS warning to change the operation of the bearing.
Contaminants may enter or re-install possible errors. Therefore, we must be very careful removal of bearing vibration, the shaft must be properly supported, may be harmed or rolling of the power outlet.
Demolition and beyond pre-set in the case of a few screws around the outside of a screwdriver squeeze, tighten the screw terminals. Side of the demolition. These are usually cover the screw holes clogged shaker tapered roller bearings, bearing on the shoulders of a single set of several incisions housing blocks, mats, delete, and press, or excavation demolition. Secondly, bearing cylindrical hole round vibrating screen can be pulled out of a simple mechanical pressure of the latest demolition demolition. At this point, we should pay attention to the inherent strength to withstand the tension.
Degree rotating ring burning amount of interference may occur and should become smaller and smaller. As long as the operating temperature to ensure that the impact of thermal expansion, maximum speed and centrifugal force, in order to prevent the surface creep or slide tight. Workload at a fixed ring and TIMKEN bearing size, select a very small clearance fit or interference fit, too loose or too tight, not conducive to maintaining the original shape completely.
