Classification of spherical roller bearing and spherical roller bearing and useful devices

Spherical roller bearings are divided into: cylindrical inner hole and cone inner hole. Cone inner hole of rear taper 1:12 respectively, code-named K of spherical roller bearing, Type 153000 or 113000) Rear and 1:30, code-named K30 spherical roller bearing. This kind of bearing with conical shaft timing, the axial move can adjust the bearing inner ring radial clearance. To the rear, code-named K, K30 cone hole spherical roller bearing, gear, on the matching set of set of rear becomes code-named K + H and K30 + H the bearing. In this kind of bearing can not shoulder on the optical axis of applicable to demand often device and remove the bearings. In order to improve the smooth performance of bearing, the bearing outer ring car has a ring groove and an average spread of three oil hole is drilled, then buy code-named W33. Main applicable insist: stamping steel enhanced insist ( The suffix E, the domestic few) 。 Stamping steel plate type stick to ( The suffix CC) , glass fiber reinforced polyamide 66 stick to ( The suffix TVPB) And machined brass plate stick to ( The suffix MB) 。 Machined brass one-piece stick to ( The suffix CA) Stamping steel plate, vibration places insist ( The suffix JPA) 。 Brass insist (vibration places The suffix EMA) 。 On the same structure, bearing code or have different. Main use: papermaking machinery, installation, railway vehicle axle reducer, gear box bearing, rolling mill, rolling mill rolls, crusher, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reducer, vertical arrange ushering self-aligning bearing. Spherical roller bearing with two race between inner ring and groove for spherical outer ring, equipped with cylindrical roller bearing. On the surface of the outer ring raceway curvature center and bearing center differences, so with automatic self-aligning ball bearing the same tone heart function. Present deflection in axis, a hood, can automatically adjust load and two direction axial load. Radial load can be big, suitable for the condition of heavy load, impact load. Inner circle diameter is tapered bore the bearing, can be directly. Or the use of set cover, remove the cylinder device on the cylindrical shaft. Adhere to the frame using steel plate stamping, polyamide forming keep frame and copper alloy frame system adhere to. About the self-aligning bearing, the shaft bearing load case shaft hole, using intermediate device can avoid outer ring tilt and rotate. Should keep in mind that some of the size of the self-aligning ball bearing of ball protrudes from the side of the bearing, so the intermediate gear ring should be recessed, in case of damage to the ball. A lot of bearing and ordinary mechanical or hydraulic pressure into laws to stop using device. About do not type bearings, inner ring and outer ring can separate device, thus simplify the installation process, especially when the inside and outside the circle must be especially interference fit. In the inner ring has been in place of the axial load including outer ring of bearing box, must pay attention to check the inner and outer circle can correctly to, in order to prevent the scratch bearing raceway and rolling parts. If a cylinder and needle bearing with without the inner ring or side of the flange rim flange edge of inner ring, the initiative to use gear sleeve. Outside diameter should be equal to the inner ring raceway diameter of sleeve F, machining tolerance specification should be d10. Drawn cup needle roller bearing is best use the spindle unit. Device of spherical roller bearing axial clearance, available on the journal of adjusting nut, adjusting shim and bearing hole of the thread, or use the way such as preloaded spring stop adjustment. The size of the axial clearance, and the bearing assembly when decorate, interval between bearing and shaft is associated with the data of bearing seat, can according to the working conditions. On high load high speed of spherical roller bearing, adjust clearance, must think temperature influence on axial clearance, clearance has reduced the temperature rise of provoking budget amount, that is to say, the axial clearance to properly adjust a bit bigger. On low speed and accept the vibration of the bearing, no clearance should be taken to device, exerted load or the device. Its purpose is to make the spherical roller bearing roller and raceway produce good contact, load average spread, avoid the roller and raceway is impacted by the vibration were destroyed. After adjustment, the axial clearance with the size of the dial gauge test. Way is to dial gauge fixed on the fuselage or bearing seat, shiny appearance of dial gauge contact to resist axis, around along the axial shaft, whose hands of throwing is the largest axial clearance value.
