Description
本發明是提供一種曲柄軸穩定結構，尤指一種減少引擎額外轉動力磨耗的曲柄軸箱蓋。The present invention provides a crankshaft stabilizing structure, and more particularly to a crankcase cover that reduces the wear of the engine's additional rotational force.
近年來機車引擎日新月異，業者除了對引擎改良之外，也對引擎的從動零件進行改造，其目的無非是想要更快速及更強大的馬力追求。In recent years, the engine of the locomotive has been changing with each passing day. In addition to improving the engine, the manufacturer has also modified the driven parts of the engine. The purpose is to find a faster and more powerful pursuit of horsepower.
請參閱第1圖及第2圖所示，一般引擎主缸體1一側延設一曲柄軸11，該曲柄軸11的內側設置一軸承100，該軸承100配合設置在一引擎曲柄軸蓋體101內部設置的一軸承座(圖未示出)，該軸承座設有一軸孔102，該曲柄軸11穿伸該引擎曲柄軸蓋體101設置的軸孔102外，再將曲柄軸11再穿過一曲柄軸箱蓋12內部設置一油封座120中的一油封121之孔122外，再與一葉輪2的軸孔21及一保護蓋體22的軸孔221組配，然當該曲柄軸11帶動葉輪2旋轉時，藉此葉輪2散發引擎內部之熱量，但是該曲柄軸11與葉輪2之間形成間距，容易使曲柄軸11於旋轉當中產生晃動、轉動不穩定，導致曲柄軸箱蓋12內側的油封121因曲柄軸11晃動而擴張，喪失防漏功效，又因曲柄軸11於旋轉中晃動而轉動效果不佳，造成引擎馬力輸出的磨阻。Referring to FIG. 1 and FIG. 2 , a crankshaft 11 is extended on one side of the main engine main cylinder 1 , and a bearing 100 is disposed on the inner side of the crankshaft 11 . The bearing 100 is cooperatively disposed on an engine crankshaft cover. A bearing seat (not shown) is disposed inside the housing. The bearing housing is provided with a shaft hole 102. The crank shaft 11 extends beyond the shaft hole 102 provided by the engine crank shaft cover 101, and then the crank shaft 11 is re-worn. The inside of the crankcase cover 12 is disposed outside the hole 122 of an oil seal 121 in the oil seal seat 120, and then is coupled with the shaft hole 21 of the impeller 2 and the shaft hole 221 of the protective cover 22, and then the crank shaft When the impeller 2 rotates, the impeller 2 dissipates the heat inside the engine, but the crank shaft 11 and the impeller 2 form a gap, which easily causes the crankshaft 11 to sway during rotation, and the rotation is unstable, resulting in the crankcase cover. The oil seal 121 on the inner side of the 12 is expanded by the crankshaft 11 to be swayed, and the leakage prevention effect is lost, and the crankshaft 11 is swayed during the rotation, and the rotation effect is poor, resulting in the wear resistance of the engine horsepower output.
因此，發明人依據上述缺點，提出一種曲柄軸穩定結構，改進習知的缺點。Therefore, the inventors have proposed a crankshaft stabilizing structure in accordance with the above disadvantages, and have improved the conventional disadvantages.
本發明的主要目的，在於透過曲柄軸箱蓋內部增設一滾珠軸承，增進曲柄軸轉動的穩定性。The main object of the present invention is to increase the stability of the crankshaft rotation by adding a ball bearing inside the crankcase cover.
本發明藉由上述技術可達到至少具有下列優點：The present invention can achieve at least the following advantages by the above technology:
1.本發明藉由曲柄軸穩定結構，以穩定葉輪與曲柄軸之間的穩固性，更能減少曲柄軸旋轉的晃動所造成的油封擴張及引擎馬力的額外磨阻，達到引擎馬力的增進。1. The invention stabilizes the structure by the crankshaft to stabilize the stability between the impeller and the crankshaft, and can further reduce the oil seal expansion caused by the sway of the crankshaft rotation and the additional wear resistance of the engine horsepower, thereby achieving an increase in engine horsepower.
2.本發明於曲柄軸箱蓋設置有一供該曲柄軸穿伸之凹軸部，該凹軸部的下方設有供一滾珠軸承放置的一軸承座及其上方設有供一油封放置的一油封座，藉由該曲柄軸箱蓋內部設置的滾珠軸承與油封，使該曲柄軸與葉輪之間無間距，令曲柄軸於旋轉當中不會產生晃動，轉動效果佳。2. The present invention is provided with a concave shaft portion for the crank shaft to extend through the crank axle cover, a bearing seat for a ball bearing and a oil seal for an oil seal disposed above the concave shaft portion The ball bearing and the oil seal provided inside the crankcase cover have no gap between the crankshaft and the impeller, so that the crankshaft does not sway during the rotation, and the rotation effect is good.
