7.1鑄鋼料的許用擠壓應(yīng)力 2p53.210.9874MPadlh 所選鍵的強(qiáng)度滿足。 九減速器的各部位附屬零件的設(shè)計(jì). 1窺視孔蓋與窺視孔： 在減速器上部可以看到傳動(dòng)零件嚙合處要開(kāi)窺視孔, 大小只要夠手伸進(jìn)操作可。 以便檢查齒面接觸斑點(diǎn)和齒側(cè)間隙,了解嚙合情況.潤(rùn)滑油也由此注入機(jī)體內(nèi). 2放油螺塞 放油孔的位置設(shè)在油池最低處，并安排在不與其它部件靠近的一側(cè)，以便于放 油，放油孔用螺塞堵住并加封油圈以加強(qiáng)密封。 3油標(biāo) 油標(biāo)用來(lái)檢查油面高度，以保證有正常的油量.因此要安裝于便于觀察油面及油面穩(wěn)定之 處即低速級(jí)傳動(dòng)件附近；用帶有螺紋部分的油尺，油尺上的油面刻度線應(yīng)按傳動(dòng)件浸入深 度確定。 4通氣器 減速器運(yùn)轉(zhuǎn)時(shí)，由于摩擦發(fā)熱,機(jī)體內(nèi)溫度升高，氣壓增大，導(dǎo)致潤(rùn)滑油從縫隙向外 滲漏,所以在機(jī)蓋頂部或窺視孔上裝通氣器，使機(jī)體內(nèi)熱空氣自由逸處，保證機(jī)體內(nèi)外壓 力均衡，提高機(jī)體有縫隙處的密封性，通氣器用帶空螺釘制成. 5啟蓋螺釘 為了便于啟蓋，在機(jī)蓋側(cè)邊的邊緣上裝一至二個(gè)啟蓋螺釘。在啟蓋時(shí)，可先擰動(dòng)此螺釘頂 起機(jī)蓋；螺釘上的長(zhǎng)度要大于凸緣厚度，釘桿端部要做成圓柱形伙半圓形，以免頂壞螺紋； 螺釘直徑與凸緣連接螺栓相同。 在軸承端蓋上也可以安裝取蓋螺釘,便于拆卸端蓋.對(duì)于需作軸向調(diào)整的套環(huán),裝上二個(gè)螺 釘,便于調(diào)整. 6定位銷 為了保證剖分式機(jī)體的軸承座孔的加工及裝配精度，在機(jī)體聯(lián)接凸緣的長(zhǎng)度方向兩端各安 35 置一個(gè)圓錐定位銷。兩銷相距盡量遠(yuǎn)些，以提高定位精度。如機(jī)體是對(duì)稱的,銷孔位置不 應(yīng)對(duì)稱布置. 7環(huán)首螺釘、吊環(huán)和吊鉤 為了拆卸及搬運(yùn)，應(yīng)在機(jī)蓋上裝有環(huán)首螺釘或鑄出吊鉤、吊環(huán)，并在機(jī)座上鑄出吊鉤。 8調(diào)整墊片 用于調(diào)整軸承間隙,有的起到調(diào)整傳動(dòng)零件軸向位置的作用. 9密封裝置 在伸出軸與端蓋之間有間隙,必須安裝密封件,以防止漏油和污物進(jìn)入機(jī)體內(nèi). 十防滑方式的確定 1滾動(dòng)軸承的潤(rùn)滑 滾動(dòng)軸承的潤(rùn)滑采用脂潤(rùn)滑，它不易流失密封性好加脂周期長(zhǎng)。 該滾動(dòng)軸承的工作溫度不太高的可選鈣基潤(rùn)滑脂，滾動(dòng)軸承摩擦力大?？蛇x 1號(hào)潤(rùn)滑 脂 GB491-87 2齒輪的潤(rùn)滑 由于展開(kāi)式齒輪的傳動(dòng)速度比低，載荷大，油脂容易流失，所以采用粘度很高，防銹 性好的開(kāi)式齒輪油。采用油池潤(rùn)滑，自然冷卻，侵入油中的齒輪深度為 1-2個(gè)齒高， 采用液壓油 GB1118.1-1994. 附注： 參考數(shù)據(jù) 吳宗澤，羅圣國(guó)主編機(jī)械設(shè)計(jì)課程設(shè)計(jì)手冊(cè)。

Below I introduce our country reduction gear the development present situation
First, the domestic reduction gear many by the gear drive, the worm drive primarily, but has the power and the load ratio generally is small, or velocity ratio great and mechanical efficiency excessively low question.Moreover, in the material quality and the technological level also has many weakness, the large-scale reduction gear question is specially more prominent, the service life is not long.The domestic use large-scale reduction gear (above 500kw), many from overseas (for example Denmark, Germany and so on) imports The 60's start few tooth reduction gears and so on difference transmission, cycloid pin gear transmission, overtone transmission which produces has the velocity ratio to be big, volume small, mechanical efficiency higher merit? .But its transmission theory limit, cannot transmit the oversized power, the power all must be smaller than generally 40kw. Because in the transmission theoretically, the technological level and the material quality aspect has not broken through, therefore, has not been able fundamentally to solve the transmission power in a big way, the velocity ratio big, the volume small, the weight light, mechanical efficiency higher these requests basically.The 90's initial period, the home appears three links (gear) the reduction gear, is one kind of outside stable motion gear drive reduction gear, it may realize the great velocity ratio, transmission load ability is also big. Its volume and the weight are all lighter than the dead axle speed reducer gear, the structure is simple, the efficiency is also high.Because this reduction gear three axle parallel structure, therefore caused the power/volume (or weight) the ratio is still small.Also its input axis and the output shaft on the identical spool thread, this do not have in the use many inconveniently. Not only Beijing Institute of Technology develops in successful " stable motion speed reducer gear " to have outside three link reduction gear merit, but also has the big power/weight (or volume) the ratio, as well as the input axis and the output shaft on identical spool thread merit, is at the domestic leading position.The home has the minority college and the factory and mining enterprise does the research work to in stable motion gear drive certain principles, has published some research paper, in has done some work using the cycloidal tooth crop rotation stable motion reduction gear.
Second, the stable motion speed reducer gear principle of work synopsis, the stable motion speed reducer gear is refers to in a counter gear transmission, a gear in the stable motion generator actuation mean plane parallel motion, meshing through tooth profile between, actuates another tooth crop rotation dead axle to decelerate the rotation, the realization reduction gear function.The stable motion generator may use the parallelogram organization, either sine organization or cross slide organization.This achievement uses the parallelogram organization to take the stable motion generator. The stable motion generator may be the hypothesized use parallelogram organization, also may be the entity use parallelogram organization.Has the practical value stable motion gear mechanism for in counter gear organization, therefore may divide into the internal tooth crop rotation stable motion movement and the external tooth crop rotation stable motion movement two kind of situations.Outside the stable motion gear reduction organization, its internal tooth crop rotation stable motion movement, actuates the external gear and makes the deceleration rotation output.This organization also calls three links (gear) the reduction gear. As a result of the internal tooth crop rotation stable motion, two crank centers establish outside the annular gear tooth ring, therefore its size is not compact, cannot solve the volume major problem.? In stable motion gear reduction, its external tooth crop rotation stable motion movement, actuation internal tooth crop rotation deceleration rotation output.As a result of the external tooth crop rotation stable motion, two crank centers can establish in the external gear tooth ring, reduced the organization overall size greatly. Because in stable motion gear mechanism transmission efficiency high, volume small, input output coaxial line, therefore by widespread application prospect.
Third, this project technical characteristic and key technologies? 1. this project technical characteristics, in this new " stable motion speed reducer gear " and domestic and foreign had the speed reducer gear compares, has the following characteristic: (1) velocity ratio scope is big, gets up from I=10, may reach most greatly several thousand.If manufactures the great velocity ratio the reduction gear, then demonstrates this reduction gear the merit.(2) transmission power scope is big: And may connect a body manufacture with the electric motor. (3) structure simple, the volume small, the weight is light.Reduces about 1/3 compared to the existing speed reducer gear.(4) mechanical efficiency is high.95 (5) this reduction gear input axis and the output shaft are on the identical spool thread.This reduction gear see Table 1 with other reduction gear performance comparison. Because lacks the data, various reduction gears power/load ratio which in the table arranges in order is most superior.? Table 1? Each kind of reduction gear comparison model power (kw) reduction gear ratio quality (kg) QI-450? 93 31.5 1820 ZSY-250? 95 31.5 540 NGW-92 88.1 31.5 577 SEW (Germany)? 90 28.61 1300 NP-100? 100 30 400 Note: NP-100 is in the stable motion speed reducer gear, the SEW reduction gear quality contains the electrical machinery.2. this project key technologies? May know by Figure 2, in “stable motion speed reducer gear " is by annular gear Z2, external gear Z1 and the parallelogram organization combination becomes.Its transmission principle is: The electrical machinery input rotary motion, the external tooth crop rotation parallel migration, its center of circle path is a circle, makes the dead axle rotation with it meshing annular gear. Because external tooth crop rotation parallel migration, therefore name stable motion gear mechanism.The gear parallel migration needs to have the auxiliary body help realization, may use (6~12) to sell the axis, the roller takes the hypothesized auxiliary stable motion organization, also may use the eccentric shaft to take the entity auxiliary stable motion organization.In the stable motion speed reducer gear key technologies and the essential craft are the composition parallelogram component size computation and the request processing precision, the gear teeth main parameter choice. These factors will all affect the transmission ability and the transmission quality.Overall speaking, the group cost reduction gear various spare parts all request to have the high precision, they will be deciding the reduction gear overall transmis3. this project survey this project has obtained the Chinese practical new patent, the patent number: ZL95227767.0? .? This project trial produced the first prototype from 1995 (power 2.5kW, after velocity ratio I=32), with some factory and mine cooperation, has one after another designed following several kind of different powers, the different velocity ratio reduction gear.(1) electrically operated on rollers gate uses the reduction gear, power 550W, velocity ratio I=26, is united as one body with the electrical machinery.sion quality. (2) mixer uses the reduction gear, power 370W, velocity ratio I=17.(3) some military goods use two kind of reduction gears, one kind of power 370W, velocity ratio I=23.5; Another kind of power 370W, velocity ratio I=103 two level of transmission reduction gear.(4) steel mill large package rotary abutment reduction gear, power 7.5kw, velocity ratio I=64.(5) steel mill table reduction gear, power 7.5kw, transmission I=11. In this patent foundation, has developed one kind of new ultra-large reduction gear, the power may reach 1000kw, at present is developing subminiature (outlook size for a millimeter level) miniature reduction gear.

（一）、國(guó)內(nèi)的減速器多以齒輪傳動(dòng)、蝸桿傳動(dòng)為主，但普遍存在著功率與重量比小，或者傳動(dòng)比大而機(jī)械效率過(guò)低的問(wèn)題。另外，材料品質(zhì)和工藝水平上還有許多弱點(diǎn)，特別是大型的減速器問(wèn)題更突出，使用壽命不長(zhǎng)。國(guó)內(nèi)使用的大型減速器（500kw以上），多從國(guó)外（如丹麥、德國(guó)等）進(jìn)口。60年代開(kāi)始生產(chǎn)的少齒差傳動(dòng)、擺線針輪傳動(dòng)、諧波傳動(dòng)等減速器具有傳動(dòng)比大，體積小、機(jī)械效率高等優(yōu)點(diǎn)?。但受其傳動(dòng)的理論的限制，不能傳遞過(guò)大的功率，功率一般都要小于40kw。由于在傳動(dòng)的理論上、工藝水平和材料品質(zhì)方面沒(méi)有突破，因此，沒(méi)能從根本上解決傳遞功率大、傳動(dòng)比大、體積小、重量輕、機(jī)械效率高等這些基本要求
