Embodiment Construction

[0028] Such as Figure 1-3 As shown, the present invention provides a bearing assembly with a rotary transformer, including a bearing and a rotary transformer. The bearing includes a bearing inner ring 1, a bearing outer ring 2 located radially outside of the bearing inner ring 1, and a bearing outer ring 2 arranged on the The bearing ball 3 between the bearing inner ring 1 and the bearing outer ring 2, the rotary transformer includes a rotor 4 and a stator 5, wherein the rotor 4 and the bearing inner ring 1 are integral structures, and the stator 5 and the bearing outer ring 2 are also integral structures. The integral structure (or one-piece structure) can be integrally formed by two parts (such as forging, casting, etc.), or it can be connected to each other (such as welding, threaded connection, snap connection, hinged connection, etc.) ).

[0029] By processing or manufacturing the bearing and the resolver into an integral structure, the complexity of installing and dis...

Abstract

The invention provides a bearing assembly with a rotary transformer. The bearing assembly comprises a bearing and the rotary transformer, wherein the bearing comprises an inner bearing ring (1) and bearing balls (3), wherein the bearing balls (3) are arranged between the inner bearing ring (1) and an outer bearing ring (2); the rotary transformer comprises a rotor (4) and a stator (5); the rotor (4) and the inner bearing ring (1) are in an integral structure; and the stator (5) and the outer bearing ring (2) are also in the integral structure. Through the bearing assembly, the assembly and disassembly complexity of two components can be effectively lowered; the bearing assembly can be relatively conveniently installed on and dismantled from a main body component, especially a motor shaft; the maintenance complexity is greatly lowered; meanwhile, the cost of the integral structure is also reduced; the reliability is also improved; and the installation and production efficiency of a motor is improved. The invention further relates to the motor with the bearing assembly.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a bearing assembly with a rotary transformer and a motor with the same. Background technique [0002] The essential components for the installation of industrial motors in the prior art are the support bearings on the front and rear end faces, and the resolver used to detect the position, displacement and speed of the rotating shaft. After assembly, use a special end cover to install a resolver, and then lead out the resolver wires to connect to the drive controller. However, due to the two installations of the supporting bearing and the resolver, the complexity of the installation process is increased, and once any of the two parts is damaged, the entire motor needs to be reinstalled, and the manufacturing cost of the two parts is also greater than that of a whole parts. [0003] Due to the technical problems of complex installation, disassembly and maintenance of t...
