Description
本發明係提供一種空氣壓縮機之傳動機構，尤指一種空氣壓縮機之傳動機構中的軸承形成非全圓形的構造，使空氣壓縮機之活塞體在壓縮筒內進行高頻率運作時，非全圓形的軸承能夠恆固在機體上而不會造成空轉或脫落的現象。 The invention provides a transmission mechanism of an air compressor, in particular, a bearing in a transmission mechanism of an air compressor forms a non-fully circular structure, so that the piston body of the air compressor operates at a high frequency in the compression cylinder, Fully round bearings can be fixed to the body without causing idling or falling off.
參閱第九圖及第十圖，顯示一習用的空氣壓縮機1，該空氣壓縮機1包含一基座11、結合在該基座上的一壓縮筒12、組裝在該基座上的一馬達13及可受該馬達13帶動而在該壓縮筒12內作往復運動的一活塞體14。透過馬達13帶動活塞體在壓縮筒12內作往復運動以完成氣體的吸入、壓縮及加壓氣體的排出。 Referring to the ninth and tenth drawings, a conventional air compressor 1 is shown. The air compressor 1 includes a base 11, a compression cylinder 12 coupled to the base, and a motor assembled on the base. 13 and a piston body 14 that is reciprocated within the compression cylinder 12 by the motor 13. The piston body is driven by the motor 13 to reciprocate in the compression cylinder 12 to complete the suction, compression and discharge of pressurized gas.
一般而論，習用空氣壓縮機1的馬達13係藉由一齒輪機構15及一曲柄機構的傳動來驅使活塞體作往復運動。該齒輪機構15包含裝設在馬達13心軸131上的第一齒輪(原動齒輪)151及與第一齒輪151相嚙合的一第二齒輪(從動齒輪)152，而曲柄機構包含一重力塊161、一軸桿162及一連桿163，軸桿162的一端穿過第二齒輪152並安裝在基座11上所設之一軸孔110內，於軸孔110內通常設有一金屬套筒或軸承111，軸承111為全圓形之形狀構造，且連桿163之一端係樞設於活塞體之活塞桿141的一末端142上的圓孔143，由於連桿163相對於軸桿162係為偏心，當第二齒輪152受 第一齒輪151帶動時，活塞體就會在壓縮筒12內作往復運動。 In general, the motor 13 of the conventional air compressor 1 drives the piston body to reciprocate by the transmission of a gear mechanism 15 and a crank mechanism. The gear mechanism 15 includes a first gear (priming gear) 151 mounted on the spindle 13 of the motor 13 and a second gear (driven gear) 152 meshing with the first gear 151, and the crank mechanism includes a gravity block 161. A shaft 162 and a connecting rod 163. One end of the shaft 162 passes through the second gear 152 and is mounted in a shaft hole 110 provided in the base 11. A metal sleeve or bearing is usually disposed in the shaft hole 110. 111, the bearing 111 is of a full circular shape, and one end of the connecting rod 163 is pivotally disposed on a hole 143 of one end 142 of the piston rod 141 of the piston body, since the connecting rod 163 is eccentric with respect to the shaft 162 When the second gear 152 is subjected to When the first gear 151 is driven, the piston body reciprocates in the compression cylinder 12.
然而，習用空氣壓縮機1之活塞體在壓縮筒12內作往復運動的過程中，常常會有變形運動的產生，以致影響空氣壓縮機的效率及降低該空氣壓縮機的使用壽命。經發明人深入研究之後，發現原因之一來自於壓縮筒12與基座11之間的距離過長造成，亦即，如第十圖所示，因為齒輪機構15設在壓縮筒12與基座11之間的緣故，在壓縮筒12之中心與基座11內側緣之間具有一較長的距離(D)，由於該較長距離(D)的存在，造成連桿163之離心方向的運動會大大地影響軸桿162的轉動，使得當活塞體在進行往復運動時，提供軸桿162安裝的軸孔110之內壁會因受力不平均而在某一點先形成磨損，又當軸孔110磨損之後，該軸桿162的旋轉(如第十一圖之標號A所示)便形成非定點圓心之運動，一旦產生此種現象，該連桿163的旋轉(如第十一圖之標號C所示)亦隨著形成非圓形之運動，進而使得活塞體之閥頭在壓縮筒12內進行往復運動時便會產生變形運動(如第十圖之虛線所示)，導致活塞體的閥頭及軸孔內的軸承容易破壞，壽命降低。 However, in the process of reciprocating the piston body of the conventional air compressor 1 in the compression cylinder 12, deformation motion is often generated, which affects the efficiency of the air compressor and reduces the service life of the air compressor. After intensive research by the inventors, one of the reasons was found to be caused by the excessive distance between the compression cylinder 12 and the susceptor 11, that is, as shown in the tenth figure, since the gear mechanism 15 is provided on the compression cylinder 12 and the pedestal. Between 11 and 11, there is a long distance (D) between the center of the compression cylinder 12 and the inner edge of the base 11, due to the existence of the longer distance (D), the movement of the link 163 in the centrifugal direction The rotation of the shaft 162 is greatly affected, so that when the piston body is reciprocating, the inner wall of the shaft hole 110 provided with the shaft 162 is firstly worn at a certain point due to uneven force, and the shaft hole 110 is formed. After wear, the rotation of the shaft 162 (as indicated by reference numeral A in Fig. 11) forms a motion of the center of the non-fixed point. Once this phenomenon occurs, the rotation of the link 163 (e.g., reference numeral C of the eleventh figure) Also shown is a non-circular movement that causes the valve head of the piston body to undergo a reciprocating motion within the compression cylinder 12 (as indicated by the dashed line in the tenth figure), resulting in a piston body valve The bearings in the head and shaft holes are easily broken and the life is reduced.
本發明人有鑑於此，乃悉心從事設計，於今有本發明產生。緣此，本發明之主要目的在提供一種可提高活塞體運動穩定性的空氣壓縮機之傳動機構，藉以改善上述習用空氣壓縮機的缺點，進而提高空氣壓縮機及活塞體的使用壽命。 The present inventors have in view of this and have been engaged in design and have produced the present invention.

Of course, the second positioning hole 32 of the base 3 can still be matched with the corresponding configuration as the second, sixth, and seventh figures are implemented. status.
統觀前論，本發明係提供空氣壓縮機2之活塞體5在壓縮筒4 內進行往復運動之傳動機構中之曲柄體63的軸桿631所連結固定的軸承8，其外輪81係為非全圓形之形狀構造，而固定該軸承8之基座3則形成相對應的第二定位孔32，使曲柄體63帶動活塞體5在壓縮筒4內作往復運動時，軸承8不會因曲柄體63之旋轉軸動力而造成空轉或脫落，使得活塞體5在壓縮筒4內的運動不僅順暢，進而可提高該空氣壓縮機2之使用壽命者。 In view of the preamble, the present invention provides a piston body 5 of an air compressor 2 in a compression cylinder 4 The bearing 8 fixedly coupled to the shaft 631 of the crank body 63 in the reciprocating transmission mechanism has an outer wheel 81 having a non-full circular shape, and the base 3 fixing the bearing 8 is formed to correspond. The second positioning hole 32, when the crank body 63 drives the piston body 5 to reciprocate in the compression cylinder 4, the bearing 8 does not idling or fall off due to the rotating shaft power of the crank body 63, so that the piston body 5 is in the compression cylinder 4 The movement inside is not only smooth, but also the life of the air compressor 2 can be improved.
前述是對本發明之構造作較佳實施例的說明，而依本發明的設計精神是可作多種變化或修改的實施例。是以，對於熟悉此項技藝人士可作之明顯替換與修飾，仍將併入於本發明所主張的專利範圍之內。 The foregoing is a description of the preferred embodiments of the present invention, and embodiments of the invention may be modified or modified. Therefore, obvious substitutions and modifications may be made by those skilled in the art, and will still be incorporated in the scope of the claimed invention.
