耐高温轴承过热的对性能与寿命的影响
Release time:2022-08-25

耐高温轴承过热的对性能与寿命的影响,如果耐高温轴承内有铁屑、毛刺、灰尘等异物进入,将使轴承在运转时产生噪声与振动,甚至会损伤滚道和滚动体。所以在安装轴承前,必须确保安装表面和安装环境的清洁。润滑对耐高温轴承的运转及寿命有极为重要的影响。润滑脂由基础油、增稠剂及添加剂制成。润滑脂的性能主要由基础油决定。一般低粘度的基础油适用于低温、高速;高粘度的适用于高温、高负荷。
(1)轴承已经损坏,应该立即更换。
(2)轴承润滑脂过少、过多或有铁屑等杂质。耐高温轴承润滑脂的容量不应超过总容积的70%,有杂质者应更换。
(3)轴与轴承配合过紧或过松。过紧时应重新磨削,过松时应给转轴镶套。
(4)轴承与端盖配合过紧或过松。过紧时加工耐高温轴承室,过松时在端盖内镶钢套。
(5)电动机两端盖或轴承盖装配不良。将端盖或轴承盖止口装进、装平,拧紧螺钉。
(6)皮带过紧或联轴器装配不良。调整皮带张力,校正联轴器。
(7)轴承润滑油太少、有杂质或油环卡住。应如加油、换新油,修理或更换油环。
