Description
本發明涉及一種齒輪傳動裝置。 The invention relates to a gear transmission.
齒輪傳動裝置之齒輪之輪齒之間相互嚙合。為保證齒輪之輪齒正常潤滑及避免因工作溫度升高而引起卡死現象,齒輪之間設有一定量之間隙。於輕負荷、扭矩變化大時、加速或減速時,齒輪之正反工作面交替變化,齒輪之間之間隙就會偏大而引起敲擊,從而增大齒輪之間之衝擊力和雜音。 The gear teeth of the gear of the gear transmission mesh with each other. In order to ensure the normal lubrication of the gear teeth and avoid the jam caused by the rising working temperature, a certain amount of clearance is provided between the gears. When the light load, the torque changes greatly, accelerate or decelerate, the positive and negative working faces of the gear alternately change, and the gap between the gears will be too large to cause knocking, thereby increasing the impact force and noise between the gears.
一種齒輪傳動裝置,其包括齒輪箱、設於齒輪箱內之第一齒輪、與第一齒輪相嚙合之第二齒輪及間隙調節機構。間隙調節裝置用於調節第一齒輪與第二齒輪之間之間隙。該間隙調節機構包括可轉動地固定於該齒輪箱內壁之固定支架、壓縮彈簧及可滑動地安裝於固定支架上之滑架。該第一齒輪之轉軸穿設該滑架。該壓縮彈簧設於該滑架與固定支架之間。該固定支架上開設有滑槽。該滑架上開設有與該滑槽相配合之肋條。該肋條沿該滑槽滑動,使該滑架相對於該固定支架僅沿一方向滑動。該壓縮彈簧抵壓滑架,滑架朝向第二齒輪滑動,使第一齒輪與第二齒輪之間之中心距減小,從而達到減小第一齒輪與第二齒輪之間之間隙之目的。 A gear transmission includes a gearbox, a first gear disposed in the gearbox, a second gear meshing with the first gear, and a clearance adjustment mechanism. The gap adjusting device is for adjusting a gap between the first gear and the second gear. The gap adjusting mechanism includes a fixing bracket rotatably fixed to an inner wall of the gear box, a compression spring, and a carriage slidably mounted on the fixing bracket. The rotating shaft of the first gear passes through the carriage. The compression spring is disposed between the carriage and the fixed bracket. A sliding slot is formed on the fixing bracket. The carriage is provided with ribs that cooperate with the sliding slot. The rib slides along the sliding slot to slide the carriage in only one direction relative to the fixing bracket. The compression spring presses against the carriage, and the carriage slides toward the second gear to reduce the center distance between the first gear and the second gear, thereby achieving the purpose of reducing the gap between the first gear and the second gear.
然,上述齒輪傳動裝置若需調節第一齒輪與第二齒輪之間之間隙時,需先打開齒輪箱,再調節彈簧之壓縮量,從而調節第一齒輪 與第二齒輪間隙。故,上述齒輪傳動裝置調節間隙較為繁瑣。 However, if the gear transmission needs to adjust the gap between the first gear and the second gear, the gear box needs to be opened first, and then the compression amount of the spring is adjusted to adjust the first gear. A gap with the second gear. Therefore, the gear transmission described above is relatively cumbersome to adjust the clearance.
鑒於上述狀況,有必要提供一種可方便調節齒輪間隙之齒輪傳動裝置。 In view of the above, it is necessary to provide a gear transmission that can easily adjust the gear clearance.

Then, the third gear 50 is sleeved on the rotating shaft 21 of the first gear 20, and the positioning protrusion 213 of the rotating shaft 21 of the first gear 20 is matched with the positioning groove 53 of the third gear 50, thereby making the first gear 20 rotates with the third gear 50. Then, the positioning member 41 and the elastic member 42 of the gap adjusting mechanism 40 are sequentially received in the receiving holes 211 of the rotating shaft 21 of the first gear 20. Then, the driving shaft 71 of the driving member 70 passes through the cover 13 of the gear box 10, and the driving member 70 is fixed to the outer wall of the cover 13 of the gear box 10. Next, the fourth gear 60 is non-rotatably sleeved on the drive shaft 71 of the driving member 70.

調節第一齒輪20與第二齒輪30之間之間隙時,使用螺絲刀等工具於齒輪箱10之外部,藉由間隙調節機構40之鎖固件43調整彈性件42之彈性變量,由於第一齒輪20與第二齒輪30為圓錐齒輪而成斜向抵持,故彈性件42之彈性變量與第一齒輪20與第二齒輪30之間之間隙量成線形關係。具體於本實施方式中,該彈性件42每壓縮1毫米,則可調整第一齒輪20與第二齒輪30之間之間隙量為0.05毫米。故,本發明之齒輪傳動裝置100可於其外部較方便且精確調節其齒輪間隙。 When the gap between the first gear 20 and the second gear 30 is adjusted, a tool such as a screwdriver is used to the outside of the gear box 10, and the elastic variable of the elastic member 42 is adjusted by the lock 43 of the gap adjusting mechanism 40, since the first gear 20 The second gear 30 is obliquely abutted by the bevel gear, so that the elastic variable of the elastic member 42 and the gap between the first gear 20 and the second gear 30 are in a linear relationship. Specifically, in the embodiment, the elastic member 42 can adjust the gap between the first gear 20 and the second gear 30 by 0.05 mm for every 1 mm of compression. Therefore, the gear transmission 100 of the present invention can adjust its gear gap more conveniently and accurately on its exterior.

The elastic member 42 is not limited to a cylindrical spring, and may be other structures such as a disc spring, a disk spring, or the like. The lock member 43 is not limited to the adjustment screw, and may be other structures, for example, a stud or the like that pierces the cover 13 of the gear case 10. The receiving hole of the first gear 20 can also be formed on the end surface of the rotating shaft 21 near one end of the small head of the first gear 20. At this time, the elastic member 42 of the side knee adjusting mechanism 40 is a tension spring.
