Description
本發明係與減速機有關，特別是指一種具間歇性潤滑機構的減速機。The invention relates to a speed reducer, in particular to a speed reducer having an intermittent lubrication mechanism.
諧波減速機是一種具有高減速比的減速裝置，在習知的結構配置上主要包含有一剛性內齒環、一設於剛性內齒環內之撓性外齒杯，以及一可轉動地設於撓性外齒杯內之波產生器，當波產生器組裝於撓性外齒杯之後，撓性外齒杯會被波產生器之外周緣所推頂而變成橢圓形，藉此，當波產生器受到動力源之驅動而開始轉動時，剛性內齒環與撓性外齒杯之間在波產生器之長軸處可以完全咬合，而在波產生器之短軸處會完全脫離，由於剛性內齒環與撓性外齒杯之間有齒數的差異，所以當波產生器持續轉動時，此一齒數差異便能達到高減速比的效果，如此即可產生高力矩之輸出。The harmonic reducer is a speed reducer with a high reduction ratio. The conventional structure includes a rigid inner ring gear, a flexible outer tooth cup disposed in the rigid inner ring gear, and a rotatably disposed In the wave generator in the flexible external tooth cup, when the wave generator is assembled in the flexible outer tooth cup, the flexible outer tooth cup is pushed up by the outer periphery of the wave generator to become an elliptical shape, thereby When the wave generator is driven by the power source to start rotating, the rigid inner ring and the flexible outer cup can be completely engaged at the long axis of the wave generator, and completely detached at the short axis of the wave generator. Since there is a difference in the number of teeth between the rigid inner ring and the flexible outer cup, when the wave generator continues to rotate, the difference in the number of teeth can achieve a high reduction ratio, so that a high torque output can be produced.
為了達到延長壽命及降低磨耗的效果，在習用技術方面具有不同的潤滑設計，例如US20080245172A1專利案，其主要在減速機內部增加注油孔與出油孔，且注油的油路設計，可以同時潤滑剛輪與柔輪以及軸承內部，透過持續注油的過程，讓油脂可以由出油孔的地方，讓波產生器獲得潤滑效果，但是由於該專利前案需要持續供油潤滑，若無持續供油潤滑則沒有任何潤滑循環效果。另一方面，US5984048A專利案，其主要在減速機內的柔輪上增加油封設計，讓油脂不會流入輸入軸，然而該專利前案只能分開不同潤滑油脂，無法達到潤滑油更新的功能，使得整體的潤滑效果會連帶受到影響。In order to achieve the effect of prolonging the life and reducing the wear, there are different lubrication designs in the conventional technology, such as the US20080245172A1 patent, which mainly adds oil injection holes and oil outlet holes inside the reducer, and the oil passage design of the oil injection can simultaneously lubricate the steel The wheel and the soft wheel and the inside of the bearing, through the process of continuous oil filling, allow the grease to be lubricated by the oil outlet, but since the patent requires continuous oil lubrication, if there is no continuous oil lubrication There is no lubrication cycle effect. On the other hand, in the US5984048A patent, the oil seal design is mainly added to the flexible wheel in the reducer, so that the grease does not flow into the input shaft. However, the patent can only separate different lubricating greases and cannot achieve the function of lubricating oil renewal. The overall lubrication effect will be affected.

The output shaft 41 of the flexible outer cup 40 is provided.
以上所述即為本發明第一實施例各主要構件的組態說明。據此，利用一外力帶動該波產生器50的輸入軸51轉動，使得該撓性外齒杯40的撓性齒杯部42彈性變形，讓該撓性外齒杯42的部分外齒421嚙合於該剛性內齒環20的內齒21，並且使該剛性內齒環20與該撓性外齒杯40互相嚙合之位置沿著一環形路徑移動，讓該撓性外齒杯40的輸出軸41可以低轉速輸出相當的扭力。此外，當本發明的減速機作動時，其進行間歇性潤滑說明如下。The above description is the configuration description of each main component of the first embodiment of the present invention. Accordingly, the input shaft 51 of the wave generator 50 is rotated by an external force, so that the flexible tooth cup portion 42 of the flexible outer tooth cup 40 is elastically deformed, and a part of the external teeth 421 of the flexible outer tooth cup 42 are engaged. The inner tooth 21 of the rigid inner ring gear 20, and the position where the rigid inner ring gear 20 and the flexible outer tooth cup 40 are in mesh with each other, moves along an annular path, and the output shaft of the flexible outer tooth cup 40 is 41 can output a considerable torque at low speed. Further, when the speed reducer of the present invention is actuated, its intermittent lubrication is explained below.
參閱圖3至圖6所示，當該撓性外齒杯40的輸出軸41以低轉速轉動時，該輸出軸41會同步帶動該軸承30的內環體32轉動，設在該內環體32上的推抵元件70也同時被帶動，當該內環體32轉動特定角度時，該推抵元件70的推抵部72則會推抵該接觸元件60接觸部61，使該接觸元件60內縮而由常態位置位移到作動位置，此時，該接觸元件60推動該儲油空間15內的潤滑油，經由該第二儲油孔152、該第一油道口221、該軸向油道22A流向該徑向油道22B，再由該第二油道口222輸出，由於該第二油道口222貫通於該內齒21，因此，潤滑油得以由該第二油道口222輸出至該內齒21，藉以對相互嚙合的該剛性內齒環20的內齒21與該撓性外齒杯40的外齒421進行潤滑作業，經由該第二油道口222輸出的潤滑油並得以順著該本體10的孔壁面131流至該軸承30的內、外環體31、32之間，以對該軸承30進行間歇性的潤滑，而達到無持續供油潤滑的狀態下仍可進行間歇性潤滑的目的。Referring to FIG. 3 to FIG. 6 , when the output shaft 41 of the flexible outer cup 40 rotates at a low rotation speed, the output shaft 41 synchronously drives the inner ring body 32 of the bearing 30 to rotate, and is disposed on the inner ring body. The pushing member 70 on the 32 is also driven at the same time. When the inner ring 32 is rotated by a certain angle, the pushing portion 72 of the pushing member 70 is pushed against the contact portion 61 of the contact member 60, so that the contact member 60 Retracting from the normal position to the actuating position, at this time, the contact element 60 pushes the lubricating oil in the oil storage space 15 through the second oil storage hole 152, the first oil passage port 221, the axial oil passage 22A flows to the radial oil passage 22B and is further outputted by the second oil passage port 222. Since the second oil passage port 222 penetrates the inner tooth 21, the lubricating oil can be output from the second oil passage port 222 to the inner tooth. 21, whereby the inner teeth 21 of the rigid inner ring gear 20 and the outer teeth 421 of the flexible outer tooth cup 40 are lubricated, and the lubricating oil outputted through the second oil passage port 222 is followed by the body. The hole wall surface 131 of 10 flows between the inner and outer ring bodies 31, 32 of the bearing 30 to intermittently the bearing 30 Lubrication, while achieving continuous lubrication without lubrication, can still be used for intermittent lubrication.
另外，當該推抵元件70的推抵部72推抵該接觸元件60的接觸部61，使該接觸元件60由該常態位置移動至該作動位置的過程中，該接觸元件60同時壓抵該彈性元件93，使該彈性元件93變形而蓄積一彈性恢復力；當該推抵元件70的推抵部72脫離該接觸元件60的接觸部61時，該彈性元件93則恢復原狀而將該接觸元件60朝該撓性外齒杯40的撓性齒杯部42方向推動，使該接觸元件60由作動位置恢復到常態位置，以等待下一次被該推抵元件70所推抵。In addition, when the pushing portion 72 of the pushing member 70 is pushed against the contact portion 61 of the contact member 60 to move the contact member 60 from the normal position to the actuating position, the contact member 60 simultaneously presses the contact member 60. The elastic member 93 deforms the elastic member 93 to accumulate an elastic restoring force; when the pushing portion 72 of the pushing member 70 is disengaged from the contact portion 61 of the contact member 60, the elastic member 93 returns to the original state and the contact is restored. The element 60 is urged in the direction of the flexible toothed cup portion 42 of the flexible outer toothed cup 40, returning the contact element 60 from the actuated position to the normal position for waiting for the next push of the push element 70.
據此，藉由該接觸元件60能夠彈性復位地設在該儲油空間15，且該接觸部61凸出於該孔壁面131，同時該減速機內更設有一推抵元件70，該推抵元件70受該內環體32或撓性齒杯部42所帶動，藉以間歇性的碰觸該接觸元件60，使該儲油空間15內的潤滑油可間歇性的釋放，以對該內齒21與該外齒421嚙合處及該軸承30進行間歇性的潤滑，而達到無持續供油潤滑的狀態下仍可進行間歇性潤滑的目的。Accordingly, the contact member 60 is elastically reset and disposed in the oil storage space 15, and the contact portion 61 protrudes from the hole wall surface 131, and a push-in member 70 is further disposed in the reducer. The element 70 is driven by the inner ring body 32 or the flexible tooth cup portion 42 to intermittently touch the contact element 60, so that the lubricating oil in the oil storage space 15 can be intermittently released to the inner tooth. 21 is engaged with the external tooth 421 and the bearing 30 is intermittently lubricated, and the intermittent lubrication can be performed without continuous lubrication.
另外，由於該本體10的儲油空間15設有一儲油口153，該儲油口153被一蓋板91所封設，因此，可視需求將該蓋板91拆離而注入新的潤滑油，而得以更新潤滑油，以提升整體的潤滑效果。In addition, since the oil storage space 15 of the main body 10 is provided with an oil storage port 153, the oil storage port 153 is sealed by a cover plate 91. Therefore, the cover plate 91 can be detached and a new lubricating oil can be injected as needed. The lubricant is updated to improve overall lubrication.
綜上所述，上述實施例及圖式僅為本發明之較佳實施例而已，當不能以之限定本發明實施之範圍，舉凡依本發明申請專利範圍所作之均等變化與修飾，皆應屬本發明專利涵蓋之範圍內。In the above, the above embodiments and the drawings are only the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, and the equivalent changes and modifications according to the scope of the present invention should be The scope of the invention is covered.
