Electric Motor Thrust Bearing

The thrust bearing is usually at the top of the motor and may consist of one or more angular contact bearings a spherical roller bearing or a hydrodynamic plate bearing.

Electric motor thrust bearing.

Open bearings with normal clearance. One of these on each end of a motor shaft will resolve all of the radial and axial forces presented by an electric motor. Another variation on the standard thrust washer is to use several in series whenever the vmax or maximum velocity in rpm exceeds the normal specification for a sliding not rolling bearing such as a single thrust washer. The bearings should enable high and low speed oper ations min i mize friction and save power.

Lock nuts requiring a keyway. A thrust bearing is either integrated with a specific main bearing assembly or independent of the main. A constant axial load being 2 of the basic static load rating co. Needle roller thrust bearings.

68 f 20 c thus a bearing temperature of 158 f 70 c measured on the bearing stationary outer ring or housing washer. Electric motor bearings the purpose of a bearing in an electric motor is to support and locate the rotor to keep the air gap small and consistent and transfer the loads from the shaft to the motor. The washers slide against flat shaft faces to keep the shaft from moving back and forth sideways. Crankshaft thrust bearings provide a fore aft gap control for axial movement or endplay of the crankshaft.

Precision lock nuts. Tapered roller thrust bearings. Motor encoder units. Rolling bearings in electric machines the purpose of using rolling bearings in electric machines is to support and locate the rotor to keep the air gap small and consistent and to transfer loads from the shaft to the motor frame.

A constant radial load being 5 of the basic static load rating co. Lock nuts with integral locking. Rolling element bearings in electric motors support and locate the rotor maintain a small and consistent air gap between the rotor and stator and transfer loads from the shaft to the motor frame. Spherical roller thrust bearings.

The bearings should be able to operate at low and high speeds whilst minimizing frictional loses. The force and direction upward downward or balanced of the applied axial load dictate the type and number of thrust bearings needed to obtain optimum performance and. These thrust bearings are located at a specific main bearing location generally at the center main or rear main depending on engine design. Sensor bearing units.
