The invention relates to the technical field of motors, in particular to a magnetic self-centering motor assembling method which is applied to a motor and comprises the following steps: forming a rotor assembly; a rotor assembly is rotatably and preliminarily installed on a base through a rotating shaft assembly, an end cover is preliminarily installed on the base, a bearing chamber of the end cover supports an outer ring of a bearing on the rotating shaft assembly through a radial elastic supporting unit, and the radial elastic supporting unit allows the outer ring of the bearing to slightly and radially float; a driving current is applied to the stator assembly, so that the rotor assembly generates a rotation trend or rotates at a low speed, and the rotor assembly is driven to overcome the micro radial rigidity of the radial elastic supporting unit by utilizing the unbalanced magnetic pulling force of interaction between the rotor assembly and the stator assembly; and the rotation axis of the stator assembly is automatically adjusted to a position which tends to be coaxial with the central axis of the stator assembly. The method can actively compensate radial dimension chain errors and assembly deviations accumulated in the previous process.

A protection structure for a power output driven shaft of a tractor comprises a power output shell. A driven shaft bearing and a driven shaft bearing clamp spring for limiting the axial movement of the driven shaft bearing are arranged in the power output shell; the power output driven shaft is mounted on the inner sides of the driven shaft bearing clamp spring and the driven shaft bearing; and the power output shell is provided with a protective flange for providing support when the driven shaft bearing snap spring deforms. Axial impact force generated by the universal transmission shaft on the power output shaft during transition of the tractor or working with a machine tool is overcome, and faults such as breakage and damage of a bearing clamp spring, early abrasion of a power output shell and tooth breaking of a gear caused by axial movement of a driven shaft due to overlarge axial impact force are prevented.

The utility model relates to a kind of taper roller bearing assembly equipment, belong to the technical field of taper roller bearing assembly.The taper roller bearing assembly equipment, comprising: press fitting machine, the inside fixed mounting of press fitting machine is equipped with press fitting seat, the top of press fitting machine is fixedly installed with electric push rod;Guiding assembly mechanism, for alignment guiding confirmation when taper roller bearing assembly The guiding assembly mechanism setting in the outside of press fitting seat;Wherein, the guiding assembly mechanism includes the press fitting rod of fixed installation in the output end of electric push rod;The assembly angle of taper roller bearing can be accurately confirmed before press fitting by guiding component, ensure that inner and outer ring and roller assembly are centered, electric push rod is only driven press fitting rod to press down after alignment up to standard, avoid misplacement and damage caused by angle deviation.Cleaning component setting in press fitting seat top, impurity and oil dirt in press fitting area can be removed before assembly, improve assembly accuracy, prevent foreign matter from causing early wear.
