我厂主要生产单列向心球轴承(最大规格311)。近两年随着对外贸易的发展,我厂按照外商的要求,承接生产“带座外球面向心球轴承”(简称“UCP轴承”)。这种轴承比单列向心球轴承形状复杂,外形也较大,因此,用现有退磁设备对其残磁进行退磁很困难,质量很差。为解决此问题,我们对洛阳轴承厂援朝产品“WD20”退磁机的电磁参数进行调整,改进了结构型式,自制成TCQ-2型退磁机。解决了对UCP轴承残磁的退 I plant mainly produces single row radial ball bearings (maximum size 311). In recent two years with the development of foreign trade, our factory in accordance with the requirements of foreign investors, to undertake the production of “spherical bearings with seat ball” (referred to as “UCP bearings”). This bearing than the single row of radial ball bearings complex shape, the shape is also larger, so the use of existing demagnetization equipment to demagnetize its residual magnet is very difficult, poor quality. In order to solve this problem, we adjusted the electromagnetic parameters of “WD20” demagnetization machine of Luoyang Bearing Factory towards North Korea to improve the structure type and made TCQ-2 demagnetization machine.
