Easy to install, convenient, safe and reliable
Prefix code - the sub-component of the bearing.
The basic code - the performance of bearing the example and size and other important features.
Post-code - the performance of bearing accuracy and material properties.
The motor bearings use smooth metal balls or rollers as well as lubricated inner and outer metal surfaces to reduce friction. These balls or rollers "carry" the load, support the motor spindle, so that the motor (rotor) can be a stable rotation.
Small and medium-sized motor to accept the majority of rotating bearings. Large and medium models also accept rotating bearings. Small motor bearings at both ends to accept ball bearings (deep groove ball bearings). The medium-sized motor receives the roller bearing at the load end (the same is usually used for high load conditions), and the non-load side accepts the ball bearing (but also has the opposite environment, such as a 1050 kW motor). The rotating bearing is greased by grease lubrication, but also effective lubricating oil lubrication.
Motor bearing placement of the pros and cons, will directly affect the bearing accuracy, life and performance. Therefore, please fully study the bearing placement, that is, including the following items, including the operation of the bearing scale bearing placement.
Bearing inner ring and the shaft is tight together, the outer ring and the bearing hole is loose together, the press can be used to press the bearing on the shaft, and then the shaft together with the bearing into the bearing hole, Bearing inner ring on the end of the pad, a soft metal material to do the device casing (copper or mild steel).
Bearing outer ring and bearing seat hole together, the inner ring and the shaft for the loose together, the bearing can be pressed into the bearing hole, then the outer diameter of the casing should be slightly smaller than the diameter of the seat hole.
If the bearing rings and shaft and seat holes are tight together, the placement of the inner and outer ring to press the shaft and seat hole at the same time, the layout of the casing should be able to balance the bearing inner and outer ring end face.
b. heating together
By heating the bearing or bearing, the use of thermal expansion will be tightly common to loose loose common arrangement. Is a commonly used and labor-saving placement. This method is suitable for the placement of larger bearing capacity, the front of the bearing or decentralized bearing rings into the tank in the symmetrical heating 80-100 ℃, and then removed from the oil as soon as possible to the shaft, Prepared to cool the inner ring end and shoulder fit is not tight, the bearing can be cooled after the axial tightening. Bearing outer ring and light metal bearing seat tight together, to accept the heating of the bearing seat hot elements, can prevent the common surface by the scratches.
When the bearing is heated with a fuel tank, there should be a grid at the positive distance from the bottom of the tank. The bearings should be hung with hooks. The bearings can not be placed on the bottom of the box to prevent the impurity from entering the bearing or unevenly heated. Thermometer, harsh control oil temperature shall not exceed 100 ℃, to prepare for tempering effect, so that the hardness of the ring down.
(1) the bearing with the fire oil wash, press into the bearing, to the bearing outer ring of the roller to add Shell No. 3 lithium grease to two-thirds full, with a net hand smear symmetry, fitted with bearing gland, Tightening bolts for tightening bolts with bolts;
(2) bearing for the table can be dispersed cylindrical roller bearings, bearings should be set on the shaft and in place;
(3) the bearing seat installed in the case, if the grease filling hole, must be aimed at the location. Tighten the bearing with fastening bolts with anti -
(4) the table in favor of the block mounted on the shaft and in place, the axis key should be the shaft key into the keyway and then install the outer part of the block, the shaft with a ring on the shaft;
(5) Tighten the solid fastening bolts, turn the adjustable pair of blocks to reach the front angular position and tighten the fastening bolts. After the above assembly is completed, the shaft should have a positive axial chord;
(6) on the vibration of the motor at both ends of the protective cover, fastened with screws.
