전동기에서 베어링 시스템의 중요성과 신중한 베어링 선택의 필요성
베어링 시스템은 전기 모터 제품의 중요하고 중요한 제어 요소이며 베어링의 성능 요구 사항은 다양한 모터 및 작동 조건에 따라 다릅니다.
일부 작동 조건에서는 모터의 부하 용량이 더 높아야 하고, 일부는 전기 모터에 축방향 부하가 필요하며, 일부 환경 조건에서는 모터에 소음이 없어야 합니다.
따라서 전기 모터용 베어링의 매칭에 신중을 기해야 합니다.
전기 모터의 베어링 맞춤 및 축 방향 이동에 대한 고려 사항
Regarding the fit between bearings and associated components, on the one hand, it is necessary to control the radial fit relationship of the bearings, and on the other hand, it is also necessary to consider the necessity of axial direction movement.
As for the shielded bearings themselves, when there is no axial force acting, or its axial force does not affect the axial clearance of the bearing life, the radial fit relationship should be considered.
From the analysis of the axial force of the electric motor bearings, for locating ball bearing, since their axial displacement has been limited by associated components, only the radial fit relationship needs to be considered.
방사형 및 축 방향 유격은 전기 모터의 설계 및 성능에 중요한 요소입니다.
그러나 전기 모터의 플로팅 엔드 베어링의 경우 선택한 베어링 유형에 따라 원통형 롤러 베어링과 관련 구성 요소 간의 맞춤 관계를 조정할 필요가 있습니다.
전기 모터의 회전자에 대한 베어링 맞춤 고려 사항
전기 모터 작동에서 회전자 회전의 특수한 특성에 따라 회전 중 내륜과 축 사이의 원주 방향 상대 운동을 방지하기 위해 고정측 베어링과 플로팅 엔드 베어링의 내부 링은 샤프트에 억지 끼워 맞춤으로 장착되어야 합니다. , 일반적으로 내부 또는 외부 링 회전으로 알려져 있습니다.
Electric motor bearings typically consist of both inner and outer rings, which are designed to support the rotating shaft and maintain its position within the motor assembly
The fit between the outer bearing ring and the bearing housing should be distinguished according to the type of bearing.
The load carrying capacity of an electric motor is an important consideration in selecting the appropriate motor for a particular application
When a separable bearing is used for the floating end, a small clearance fit between the outer ring of the bearing and the bearing housing can be used, and the clearance selection should ensure that the working clearance of the bearing during operation meets the requirements.
When a non-separable bearing is used for the floating end, there should be sufficient clearance between the outer ring of the bearing and the section of the bearing inner and outer cover stop grooves to allow for axial sliding of the bearing due to thermal expansion and contraction.
It is particularly important to emphasize that the surface roughness and roundness of the bearing housing are crucial to ensuring that the outer ring of the bearing is not damaged due to excessive external forces.
Comprehensive Evaluation of ball Bearings Clearance Control and Importance of Communication with Bearing Suppliers
The control of radial clearance of bearings is related to both the fit relationship between the inner ring of the ball bearings and the shaft, and the fit relationship between the outer ring of the bearing and the bearing housing.
Different manufacturers have different tendencies in choosing tolerances, and the effectiveness of processing parts may also vary.
Therefore, when choosing bearing clearance, a comprehensive evaluation should be conducted based on the characteristics of the specific application, and communication with the bearing supplier is particularly important.
Bearing clearance refers to the gap between the rolling elements of the deep groove ball bearings and the inner and outer ring shells of the bearing.
The amount of movement when the unfixed side of the bearing ring clearance is radially or axially moved is referred to as the bearing clearance.
According to the direction of movement, it can be divided into radial loads clearance and axial clearance.
The size of the operating clearance during operation affects the rolling fatigue life, temperature rise, noise, vibration, and other performance characteristics of the bearing.
