Description

活塞
                            技术领域
本实用新型涉及一种活塞,尤其涉及一种在活塞侧壁上有润滑油通道的活塞。
                            背景技术
目前,我们所能了解到的活塞的润滑油通道是在活塞的侧壁上有一条自下到上的槽,它使活塞在工作时即活塞在气缸中运动,活塞槽中的油对活塞起润滑作用,但是其在圆周侧壁上只是一条,使活塞工作时尤其是其相对槽的对面工作面不能充分润滑,受到的摩擦力也较大,寿命受到了影响。
                             发明内容
本实用新型的目的在于克服上述存在的缺点,提供一种使活塞在工作时其侧壁的所有部位都能充分得到润滑,其使用寿命提高。
本实用新型的活塞包括活塞座、与活塞座相连的活塞筒柱形体,所述的与活塞座相连的活塞筒柱形体的的外侧壁面上具有润滑油道,所述的润滑油道是为多个油孔,即在所述的活塞筒柱形体的轴向外侧壁上有多排孔,在其周向外侧壁上每排孔为多个,该多个孔均匀分布在所述的活塞筒柱形体的圆周上。
所述的油孔可以为15个,且在柱形体的轴向有3排孔,在柱形部分的周向每排孔为5个,5个孔均匀分布在柱形体的圆周上。
上述所述的活塞具有工作时其侧壁面上能得到充分润滑,寿命长,结构简单,加工方便等特点。
                            附图说明
图1为本实用新型的结构示意图。
                     具体实施方式
下面根据附图对本实用新型作进一步阐述:
在图1中,活塞由活塞座1、与活塞座相连的活塞筒柱形体2构成,活塞筒的柱形体外径为32mm,厚度为2mm,所述的与活塞座相连的活塞筒柱形体的外侧壁面上具有润滑油道3,所述的润滑油道3是为15个油孔,即在柱形部分的轴向有3排孔,在柱形部分的周向每排孔为5个,该5个孔均匀分布在柱形部分的圆周上。

Claims (2)

1、一种活塞,包括活塞座、与活塞座相连的活塞筒柱形体,所述的与活塞座相连的活塞筒柱形体的的外侧壁面上具有润滑油道,其特征在于:所述的润滑油道是为多个油孔,即在所述的活塞筒柱形体的轴向外侧壁上有多排孔,在其周向外侧壁上每排孔为多个,该多个孔均匀分布在所述的活塞筒柱形体的圆周上。
2、根据权利要求1所述的活塞,其特征在于:所述的油孔为15个,且在柱形部分的轴向有3排孔,在柱形部分的周向每排孔为5个,5个孔均匀分布在柱形部分的圆周上。
