Description

无油空压机的曲轴箱
技术领域
本实用新型涉及无油空压机的技术,特别是其曲轴箱技术。
背景技术
目前广泛应用的空压机多为有油空压机。由于连接在马达前端的曲轴箱内布置偏心轮,而曲轴箱内充有机油,长时间工作后,有油空压机在工作时会污染环境,而漏油也是不可避免的现象,工作中遇到缺油状况还会影响寿命。
实用新型内容
本实用新型目的在于为空压机配套设计一种无油的曲轴箱,以改善有油空压机的上述弊端。
本实用新型包括箱体,箱体的后端设有可与马达连接的开口端,在箱体内布置的偏心轮,在与偏心轮轴向平行的方向设置进风口。
本实用新型在曲轴箱的前端面开设进气口,空气从曲轴箱进入后,通过活塞连杆送气,实现无油工作,既无污染,又无缺油的安全隐患。
为防止环境空气的尘埃带入,本实用新型还在进风通道上设滤网。
为固定滤网,也便于更换、清洗,本实用新型在箱体前端设有敞开的端面,并于端面的周向设有连接螺孔,所述滤网通过两只设有条状孔的连接盖支撑在箱体的前端。
附图说明
图1为本实用新型的结构示意图;
图2为内、外连接盖的端面图。
图中,1箱体,2偏心轮,3内连接盖,4滤网,5外连接盖,6连接螺孔,7螺钉,8连接孔,9条状通孔,10通孔。
具体实施例
圆筒状箱体1的上侧壁设有通孔10,在箱体1内通过轴承支撑一偏心轮2,偏心轮2的轴向与箱体1的轴向平行。
在箱体1的前端周向对称开设四个螺孔6,两个圆形内连接盖3、外连接盖5上分别开设条状通孔9和周向的四个连接孔8,圆形滤网4通过内、外连接盖3、5的夹持和螺钉7、连接螺孔6连接在箱体1的前端。

Claims (3)

1、无油空压机的曲轴箱,包括箱体,箱体的后端设有可与马达连接的开口端,在箱体内布置的偏心轮,其特征在于在与偏心轮轴向平行的方向设置进风口。
2、根据权利要求1所述曲轴箱,其特征在于在进风通道上设滤网。
3、根据权利要求2所述曲轴箱,其特征在于在箱体前端设有敞开的端面,并于端面的周向设有连接螺孔,所述滤网通过两只设有条状孔的连接盖支撑在箱体的前端。
