Precision Ball Bearing 6201 2RS C3 Conveyor Rollers Usage Gcr15 Material
I. Product brief introduction:
Check work editor before installation of conveyor roller bearing seal.
First, check the surface quality of the shaft seal. Such as flexibility, hardness of the rubber material, moulding of residual flash, the finish of parts of the lip and tidy condition, such as storage for a considerable time sealing, must pay attention to the presence of saponification brittle or abnormal phenomenon such as extrusion deformation.
Second, the detection of shaft seal geometry size must match drawing size requirements, the process generally in the oil film bearing factory before delivery, inspection work must be equipped with simulated taper sleeve, simulated the conveyor rollers roll neck dedicated device. Check the size of the supporting roller and arc chamfer in the relevant parts of the neck seal, and do not allow the burrs and scratches. Talk about the lubrication of the roller backing bearing.
Third, the conveyor roller neck and shaft neck seal clean after the oil film bearing oil. The oil film bearing other parts are installed on the bearing pedestal according to the cleaning and installation of the general procedure of rolling oil film bearing.
II. Product advantage:
Whether the bearing installation is good or bad will directly affect the bearing's accuracy, life and performance. Therefore, please fully study the installation of bearing, i.e., bearing installation according to operation standard including the following items.
Cleaning bearings and related parts. (for grease lubricated bearings and double-sided oil seal or dust cover, no cleaning shall be required before the sealing ring bearing is installed.)
To check the dimensions and finishing conditions of relevant parts
Bearing should be installed according to the bearing structure, size and cooperate with properties of bearing parts, pressure should be directly in the tight fit on the ring width, shall not be passed on roller pressure, bearing installation commonly adopt the following methods:
A. Pressure fit
Bearing inner ring and shaft tight fit, outer ring and bearing hole is a loose fit, press the bearing to be pressed on the shaft are available, and then put the shaft together with the bearing load bearing hole, when pressed on the bearing inner ring end face, cushion the assembling casing made of a soft metal material (copper or mild steel).
When the bearing outer ring and the bearing hole are tight fit together, the inner ring and shaft are relatively loose, and the bearing can be pressed into the bearing hole. The outer diameter of the assembly casing should be slightly less than the diameter of the hole.
If the bearing ring and the shaft and the seat hole are tight fit, the mounting of the inner circle and the outer ring should be pressed into the shaft and the seat hole. The structure of the assembly sleeve should be able to hold the inner circle and the end surface of the outer ring simultaneously.
By heating the bearing or bearing seat, the thermal expansion will be used to fit the installation method of loose fitting. Is a common and labor-saving installation method. This method is suitable for interference quantity larger the installation of the bearings, the bearing before hot charging type or separable bearing ring into the fuel tank even heat 80-100 ℃, and then loaded on the shaft, as soon as possible out of the oil to prevent inner ring after cooling end face and the shoulder joint is not tight, bearing axial fastening again after cooling. When the bearing outer ring is tightly coupled with the light metal bearing seat, the hot loading method of the heating bearing seat can be used to avoid the surface chafing.
Heating tank with bearing and should be at a certain distance from the bottom of a mesh, or hanging hooks in the bearings, bearing on the bottom, in case of heavy impurities into the bearing or uneven heating, fuel tank must have a thermometer, strictly control the oil temperature shall not exceed 100 ℃, in order to prevent the tempering effect, reduce the hardness of the ring.
