Abstract

本实用新型涉及一种背衬轴承,包括相互对应的轴承外圈和轴承内圈,所述轴承外圈的中部设有中挡边,轴承内圈的两端设有外挡边,轴承外圈与轴承内圈之间设有滚子,滚子上设有保持架,滚子的两端均设有密封圈,密封圈的外侧设有弹簧挡圈,弹簧挡圈与外挡边之间设有防尘盖。本实用新型的有益效果为:防尘盖与密封圈交错配置,这样就在轴承两端形成了迷宫密封结构,一方面可有效防止灰尘进入轴承内,影响轴承的精度和使用寿命,另一方面,可有效使润滑剂保存在轴承内,提高了润滑效果,同时减少润滑剂的泄漏。
The utility model relates to a backing bearing which comprises a bearing outer ring and a bearing inner ring that correspond to each other, wherein the middle part of the bearing outer ring is provided with a middle flange; two ends of the bearing inner ring are provided with outer flanges; a roller is arranged between the bearing outer ring and the bearing inner ring, and is provided with a retainer; two ends of the roller are provided with sealing rings; the outer sides of the sealing rings are provided with spring check rings; and dustproof covers are arranged between the spring check rings and the outer flanges. The backing bearing has the benefits that the dustproof covers and the sealing rings are arranged in a staggered way, so that labyrinth seal structures are formed at two ends of the bearing, therefore, on one hand, the dust can be effectively prevented from entering into the bearing to influence the accuracy and the service life of the bearing, on the other hand, a lubricating agent can be effectively stored in the bearing, so that the lubricating effect is improved, and the leakage of the lubricating agent is reduced.
