I. Product brief introduction:
Motor bearing, also known as motor bearing or motor bearing, is a special bearing used for motor.
The bearings used by the motor supporting the shaft, which can guide the rotation, and motor bearing can also bear the rotating parts of the shaft.
YSJ series compressor special motor bearing type
Shaft extension: 6204-2e-c3, 6205-2e-c3, 6206-2e-c3, 6308-2e-c3, 6309-2e-c3, 6311-c3, 6313-c3, 6314-c3, 6317-c3, 6319, 6319-c3, 6322

II. Product advantage:
Most of the small and medium motor USES rolling bearings. Large and medium sized motors also use rolling bearings. Small motor bearing at both ends.
Ball bearing (deep groove ball bearing) is used. The medium motor USES roller bearings (usually used for high load conditions) on the load side, and ball bearings are not used in the load end (but there are also the opposite, such as 1050kW motor). The rolling bearing is lubricated by grease, but also lubricates the lubricating oil.
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.
