Interchangeability of motor components

Interchangeability of motor components

In batch production and mass production of parts, without the selection and repair, arbitrarily take out a part or component of the same specification, it can be smoothly assembled to the product, and the quality of the product can be guaranteed. The nature of such parts or components of the same specification that can be interchanged is referred to as the interchangeability of the parts or components.

Parts are interchangeable and can be professionally produced by specialized workshops or factories, using advanced manufacturing methods to greatly increase labor productivity and reduce product costs. At the same time, assembly time can be shortened and the quality of the assembly can be improved. In terms of repair, when a part or part is damaged, it can be quickly replaced with a new part or part. The greater the scale of production, the more important the interchangeability of components.

In terms of the unit of use, the motor itself is often used as a component or component. First, motors of the same specification are required to be interchangeably installed, and secondly, detachable parts are required to be used interchangeably.

Dimensions related to installation and maintenance

● Center height H, that is, the height from the center of the shaft to the plane of the foot;

● shaft extension diameter D and length E, keyway width P and shaft groove depth G;

●The lateral center distance A of the foot hole and its distance from the center line A/2

● the axial center distance B of the foot hole and the distance C from the shoulder to the first foot hole;

● foot hole diameter K;

● stator inner diameter and rotor outer diameter;

● the matching size of the end cover and the base seat;

●The size of the bearing and bearing gear and bearing chamber,

● The matching size of the outer fan and the outer slip ring and the shaft extension.

Among them, A, B, C, D, H are the main installation dimensions to ensure the interchangeability of the motor; interchangeability is generally achieved by machining.
