车载用空气压缩机的轴承的定位方法及其定位构造
技术领域
本发明涉及一种空气压缩机的轴承的定位方法及其定位构造,尤其是指一种利用一冲压制具冲压于一位在轴承的内轮并伸出于轴承外表面的轴杆的顶平面,让轴杆的顶平面受到挤迫产生口径扩增的外扩垣,使得轴承可借由轴杆的外扩垣及环垣的紧密夹持而能牢固地定位的车载用空气压缩机的轴承的定位方法及其定位构造。
背景技术
参阅图9及图10,显示一习用的车载用空气压缩机1,该空气压缩机1包含一基座11、结合在该基座上的一汽缸12、组装在该基座上的一马达13及可受该马达13带动而在该汽缸12内作往复运动的一活塞体14。通过马达13带动活塞体14在汽缸12内作往复运动以完成气体的吸入、压缩及加压气体的排出。
一般而论,习用车载用空气压缩机1的马达13借由一齿轮机构15及一曲柄机构的传动来驱使活塞体14作往复运动。该齿轮机构15包含装设在马达13心轴131上的第一齿轮(原动齿轮)151及与第一齿轮151相啮合的第二齿轮(从动齿轮)152,而曲柄机构包含一重力块161、一轴杆162及一连杆164,轴杆162的一端穿过第二齿轮152并安装在基座11上所设的一轴孔110内,于轴孔110内通常设有一轴承111或金属套筒112(可同时参考图7及图8),轴承111为全圆形的形状构造,曲柄机构的轴杆162借由一螺钉17锁固于轴承111,如图8及图9所示,又或者借由一固定扣18紧扣住设置在轴孔110内的金属套筒112中的曲柄机构的轴杆162,如图7所示,且连杆164的一端枢设于活塞体14的活塞杆141的一末端142上的圆孔143,由于连杆164相对于轴杆162为偏心,当第二齿轮152受第一齿轮151带动时,活塞体14就会在汽缸12内作往复运动。
然而,习用车载用空气压缩机1的活塞体14在汽缸12内作往复运动的过程中,常常会有变形运动的产生,以致影响空气压缩机的效率及降低该空气压缩机的使用寿命。经创作人深入研究之后,发现原因之一来自于习用塑料材质的基座11会因高温而产生稍为软化的现象,因此在活塞体14高频率往复运动时,活塞体14的活塞杆141与轴承111相互牵扯的情况下,前述借由一螺钉17将轴杆162与轴承111相锁固的状况下,实际上时常发生螺钉17的阳螺纹171与轴杆162的阴螺纹163因螺牙的结合深度不够或是锁固螺钉17的扭力不够,导致轴杆162在轴承111的内轮的内径向面产生松动,更甚至造成空转,而借由固定扣18扣住金属套筒112中的曲柄机构的轴杆162的环槽165,亦会在长期的使用下,固定扣18亦会产生脱落或松动,无论用螺钉17或固定扣18将轴杆162与轴承111或金属套筒112相结合,在活塞体14高频率往复运动下都会造成轴孔110与轴承111略为偏移变形,更导致轴孔110周边的壁面被齿轮机构15的第二齿轮152的侧面壁增加相互摩擦的现象,导致活塞体14随之偏移,活塞头144无法在汽缸12保持垂向运动,稍有偏角,使得当活塞体14在进行往复运动时,提供轴杆162安装的轴孔110的内壁会因受力不平均而在某一点先形成磨损,又当轴孔110磨损之后,该轴杆162的旋转(如图10中标号A所示)便形成非定点圆心的运动,一旦产生此种现象,该连杆164的旋转(如图10中标号C所示)亦随着形成非圆形的运动,进而使得活塞体14的活塞头144在汽缸12内进行往复运动时便会产生变形运动(如图11中虚线所示),导致活塞体14的活塞头144及轴孔110内的轴承111容易破坏,寿命降低。

请参阅图2、3、5、6所示,本发明的轴承6的定位方法是利用该较小口径的轴杆52的一端穿设于第二定位孔32的轴承6的内轮62并伸出于轴承6的外表面,使轴杆52的环垣521可抵触于轴承6上,再利用一冲压制具7冲压于位在轴承6的内轮62中的轴杆52的顶平面523,让轴杆52一端的顶平面523受到挤迫产生口径扩增的外扩垣524,使得轴承6可借由轴杆52的外扩垣524及环垣521的紧密夹持而能牢固地定位。
请参阅图4所示,该冲压制具7具有一顶压头71,该顶压头71的顶平面72设有一中心凹槽73,于中心凹槽73的外缘环设有一环柱74,该环柱74外围设有多个相间隔且呈放射状排列的凸块体75,让冲压制具7的顶压头71冲压于轴杆52的顶平面523会产生出压痕。
当车载用空气压缩机2进行运作时,因传动机构的齿轮5的轴杆52直接紧密夹持住轴承6,使传动机构在运作的期间不会使轴杆52与轴承6的定位形成松动、松脱,不易导致第二定位孔32之内的轴承6被破坏,间接地让活塞头保持在汽缸4内进行上下往复直线运动的最佳状态。
综观前论,本发明提供一种车载用空气压缩机2的轴承6的定位方式及其定位构造,其利用一冲压制具7冲压于一位在轴承6的内轮62且伸出于轴承6外表面的轴杆52的顶平面523,让轴杆52一端的顶平面523受到挤迫产生口径扩增的外扩垣524,使得轴承6可借由轴杆52的外扩垣524及环垣521的紧密夹持而能牢固地定位。
