[摘要]
本設(shè)計(jì)是將一對(duì)圓錐齒輪傳動(dòng)與NGW行星機(jī)構(gòu)串聯(lián)，形成一個(gè)組合機(jī)構(gòu)，用來傳遞兩相交軸之間的運(yùn)動(dòng)和動(dòng)力，并實(shí)現(xiàn)較大的傳動(dòng)比。對(duì)齒輪與中心輪組合的受力狀況分析時(shí)，應(yīng)引入不均載系數(shù)根據(jù)傳動(dòng)，工作扭矩，載荷，根據(jù)級(jí)數(shù)轉(zhuǎn)速要求計(jì)算出齒輪的齒數(shù)，模數(shù)，分度圓直徑，計(jì)算出傳動(dòng)齒的齒厚，齒面硬度，選擇齒形，根據(jù)上述要求選定達(dá)到此要求的材料，并且做出經(jīng)濟(jì)效益最好的選擇，再根據(jù)此材料的彈性影響系數(shù)，各傳動(dòng)齒輪接觸疲勞強(qiáng)度極限，再對(duì)材料的選擇正確與否做出校核，并且要滿足減速器的使用壽命要求，根據(jù)載荷和傳動(dòng)扭矩計(jì)算傳動(dòng)主軸的直徑及定位，計(jì)算中心距，確定行星輪系的周轉(zhuǎn)圓半徑及方向，并指定輪系的旋轉(zhuǎn)方向，得到各項(xiàng)數(shù)據(jù)后，依據(jù)設(shè)計(jì)要求結(jié)構(gòu)大小，確定各部件相對(duì)位置，進(jìn)入外箱體的設(shè)計(jì)，秉承體積最小，拆裝方便的原則，定好主軸位置，窺視孔，潤(rùn)滑口在箱體上的位置，便于維修判斷。除齒輪以外，對(duì)于承受工作載荷的其他零部件如軸、鍵、軸承等、也進(jìn)行了設(shè)計(jì)校核。減速器箱體采用法蘭式結(jié)構(gòu)，用以滿足工作環(huán)境的安裝條件。減速器高速級(jí)為圓錐齒輪傳動(dòng)，以實(shí)現(xiàn)換向。由于功率、傳動(dòng)比較大，將這對(duì)圓錐齒輪設(shè)計(jì)為斜齒圓錐齒輪。低速級(jí)采用NGW行星機(jī)構(gòu)進(jìn)一步增大傳動(dòng)比，NGW行星機(jī)構(gòu)可以傳遞較大的功率以及實(shí)現(xiàn)較大的傳動(dòng)比，因此在設(shè)計(jì)中采用直齒圓柱齒輪。

[英 文]This design is a bevel gear transmission with NGW planetary bodies in series, forming a combination of institutions, to transfer the two-axis intersection between the movement and momentum and to achieve greater transmission ratio. Gear and centre round the composition of the force analysis of the situation, should be introduced under the uneven transmission coefficient, the torque, load, in accordance with the requirements in order to speed the gear teeth, module, the circle diameter, calculated Drive Tooth tooth thick, tooth surface hardness, select profile, in accordance with the requirements of the selected material to this request, and make the best choice for cost-effective, then this material under the impact of the flexibility factor, the transmission gear contact fatigue limit , And the choice of materials to check whether or not correct, and to meet the requirements of the life of reducer, according to load and transmission torque spindle drive calculated the diameter and location, from the ICC to identify planets revolving round the circle of radius And direction, and specify the round of the direction of rotation, get the data, based on the design requirements of size, determine the relative position of components into the box, the design is home to the smallest, to facilitate entry to the principle of the spindle good location, Peep hole, I lubrication in the box on the location, ease of main In addition to gear, the work load of other bear parts such as the axis, keys, the bearings, also had a design Reducer a flange-box structure to meet the conditions for the installation of the working environment.for high-speed cone gear trans mission in order to achieve commutation. As power, drive more, on this bevel gear designed to ramp bevel gear. Low level used to further increase NGW planetary transmission ratio, NGW planetary bodies can convey more power and the realization of the larger transmission ratio, used in the design of the spur gear.
