本文介绍了研制适合±50℃的制动缸活塞皮碗及相应的润滑脂。文章建议,根据试验,Y形制动缸活塞皮碗及89D号润滑脂应为今后采用的方向。旧型制动缸应以全胶L形皮碗、89D号润滑脂分别取代夹布皮碗、46号润滑脂。这些科研项目已取得了良好的密封、润滑效果,达到较长的换脂期。
This article describes the development of ± 50 ℃ brake cylinder piston bowl and the corresponding grease. Article suggested that, according to the test, Y-shaped brake piston bowl and No. 89D grease should be used in the future direction. The old brake cylinder should be full plastic L-shaped bowl, No. 89D grease were replaced cloth cloth bowl, No. 46 grease. These research projects have achieved good sealing, lubricating effect, to achieve a longer period of change.
