The utility model relates to a bearing dust-proof structure and an angle grinder. The bearing dust-proof structure includes: a main shaft; a bearing, which is sleeved on the main shaft, including the outer ring and the inner ring; an end cover, which is internally provided with a circumferential groove to hold the bearing, and a dust-proof gasket is arranged on the side wall of the output end close to the main shaft of the end cover, which at least covers the outer ring and the inner ring. The technical effect is at least as follows: one side of the circumferential groove of the bearing in the end cover is provided with a dust-proof gasket, which covers at least the outer ring and the inner ring. Since the circumferential groove of the end cover is in contact with the bearing for assembly, the dust-proof gasket is in direct contact with the bearing, and there is no gap between the two. The traditional dust-proof gasket is assembled on the main shaft, and there is a gap between it and the bearing, so the dust is easy to enter into the bearing, causing the bearing to be stuck. In this technical scheme, the dust-proof gasket is in direct contact with the bearing, so as to avoid the dust directly entering into the bearing as far as possible, the dust-proof effect is better, the service life of the bearing is prolonged, and the maintenance cost is reduced.

轴承防尘结构及角磨机
本技术涉及角磨机
,特别是涉及一种轴承防尘结构及角磨机。
技术介绍
角磨机(anglegrinder),又称研磨机或盘磨机,是一种利用玻璃钢切削和打磨的手持式电动工具,主要用于切割、研磨及刷磨金属与石材等。工作头处于切削或打磨模式时,被加工的工件产生较多的粉尘碎屑,容易进入承载主轴的轴承内,影响轴承的使用。传统的防尘方式通常是在主轴上装配防尘垫片,以减少粉尘碎屑等进入轴承内。在实现传统技术的过程中,专利技术人发现:传统的防尘方式依然存在较多的粉尘碎屑等进入轴承内的现象,影响轴承的使用。
技术实现思路
基于此,有必要针对传统的防尘方式依然存在较多的粉尘碎屑等进入轴承内的现象,影响轴承的使用的问题,提供一种轴承防尘结构及角磨机。本技术提供一种轴承防尘结构,包括:主轴;轴承,套设于所述主轴,所述轴承包括外圈和内圈;端盖,所述端盖内开设有周向卡槽,以容置所述轴承,所述端盖于所述周向卡槽的靠近所述主轴的输出端的侧壁设有防尘垫片,所述防尘垫片至少覆盖所述外圈和所述内圈。 ...
