This kind of bearing the lubrication oil and gas is xiao zhang: early belong to accidental, the motor with a current-carrying conductor and magnetic circuit structure, usually cause axial magnetization or cause pulsating magnetic flux.
Produced in surface fatigue spalling, under the action of alternating stress, shear stress occurs in about depth from surface, the weak spot of the material is the first article of the tiny crack formation, and in again and again under the action of alternating stress, crack expanding and value-added.
The purpose of the determination of the motor shaft voltage is to know the size of the motor shaft current.
Determine the purpose of the motor shaft current is obtained directly through the motor bearing current value.
For alloy layer thickness, table outer material quality inspection table outer heat treatment quality grade project supporting organization/austenite martensite structure levels/carbide mesh/hardness HRC outer ring.
End of installation of two bearings in the form of back to back, the back-end put a cylindrical roller bearing, the back-end to install a bearing, and a few spring down the outer ring to clearance.
Rotation accuracy: the spindle rotates in influencing the direction of the machining accuracy in radial and axial runout (
See the form tolerance)
Main shaft and bearing, mainly depends on the manufacturing and assembly quality.
And when choosing drive motor power, counterclockwise rotation required torque is very big, and clockwise rotation due to the effect of gravity is small, so the motor output power fluctuation is very big, and its power rating to be designed according to the big moment.
Is above circles horn screw connection shock absorption, due to the screw itself has some effect, so don't need to do round Angle parameters will not change, (4) carrying capacity of the bearing capacity of the low dynamic bearing is proportional to the viscosity, the bearing capacity of gas dynamic bearing only fractional percentage point of the fluid dynamic bearing the same size.
High-speed bearing ancestors for rotary bearing after fill grease, the grease inside the bearing full flow, and into the stable distribution, lest at startup caused by insufficient friction surface grease bearing burn out.
Nine, electric erosion phenomenon: rolling surface shape pit of the crater, progressive development of a wave plate, measures: to make current bypass valve;
Insulation measures are taken to avoid current through bearings inside.
Main features include: flange outer ring raceway outer ring is designed for lightweight structure parts through induction hardening processing, can withstand the bearing performance of high performance, the specific application of grease, lifelong sealed solid flange with a threaded hole or stud as well as the center and install the brake and the wheel pin design can be used to replace driven wheel application can install ABS pulse in the swivel ring more compact wheel hub bearing unit s s HBU to a wave of new century, to the design of the shrinking demand is still growing -
Car makers want lighter, more compact, more cost-effective components.
Traditional for axial and inner hole wear problem is adopted after removal to shaft repair workshop for repair welding, set shaft sleeve, such as processing, repair welding machining process itself is easy to make shaft surface local produce thermal stress, cause the hidden trouble of the broken shaft, repair welding and machining process need to spend a lot of manpower and time to disassembly, transport and installation of equipment, the repair time is longer, the comprehensive repair cost is high.
