求購(gòu)齒輪減速器
This new project requires >90% efficiency gear reducer or we will not meet customer requirements. Here are some more details:
這個(gè)新項(xiàng)目要求齒輪減速器的功率達(dá)到90%，否則就滿足不了客戶的要求。下面是具體要求：
Application is closing/opening doors on portable transportation equipment. Power consumption is important. Closing the door is the hard part. Needs to generate 50ftlb of torque and then 250ftlb of torque for 1 second to make sure door is tightly closed. We will provide all controller functions.
用于輕便型交通設(shè)備的開(kāi)關(guān)門(mén)裝置。功率非常重要。閉門(mén)是最困難的部分，需要先產(chǎn)生50扭力繼而在1秒鐘之內(nèi)產(chǎn)生250扭力以卻使門(mén)被緊密關(guān)閉。我們可以提供控制器的功能。
Must produce 50ftlb with 12VDC @ 20A
必須滿足輸出電壓直流12V，輸出電流20A情況下產(chǎn)生50扭力。
Estimated motor efficiency is >82% and gear reducer efficiency is >90%
With 12VDC @ 20A =240W
預(yù)計(jì)輸出電壓直流12V@輸出電流20A=輸出功率240W情況下電機(jī)功率為82%，減速器功率為90%
240W @ 82% efficient = 196W output to gear reducer
240W的82%=196W輸入給減速器
196W x 150 x .90 = 26460W output from gear reducer with 90% efficient
功率為90%情況下減速器的實(shí)際輸出功率為196W x 150 x .90 = 26460W
Required output speed is 25rpm at gear reducer
Thus, required DC motor speed is 3750rpm (25 x 150)
Required torque @ 25rpm is 600inlb for 1 minute (output of gear reducer)
要求減速器的輸出速度為25轉(zhuǎn)/分，因此要求直流電機(jī)的輸出速度為3750轉(zhuǎn)/分（25 x 150），要求25轉(zhuǎn)/分時(shí)1分鐘內(nèi)產(chǎn)生600扭力（減速器的輸出功率）
Required torque @ stall torque is 3000 inlb (12VDC @ 100A) for 1 second
要求輸出直流電壓12V@輸出電流100A時(shí)，1秒鐘之內(nèi)失速扭矩產(chǎn)生3000扭力。
Estimated DC motor is:
4.4inlb @ 3750 rpm (rated speed and torque under full load)
Gear Reducer is estimated at 150:1 at >90% (We do not care if it is helical or planetary or cycloidal or hypoid or parallel offset, but just meet requirements).
預(yù)計(jì)直流電機(jī)：
電機(jī)在額定轉(zhuǎn)速及扭矩在滿負(fù)荷情況下，3750轉(zhuǎn)數(shù)/分時(shí)產(chǎn)生4.4扭力。
減速器的輸出功率>90%時(shí)預(yù)計(jì)輸出比在150:1（減速器的類型對(duì)我們來(lái)說(shuō)無(wú)所謂，不論是斜齒輪減速器還是行星減速器還是擺線針輪減速器還是斜齒圓柱齒輪減速器還是平行軸斜齒輪減速器，只要能滿足要求就可以）
Duty cycle is operates for 1 minute (10-15 times per day with minimum 30 minute rest period)
工作負(fù)載循環(huán)是運(yùn)行一分鐘（一天10-15次，間歇至少30分鐘）
Operates at most 60 hours per year. Must be watertight construction.
Minimum output shaft diameter is 25mm
一年最多運(yùn)行60小時(shí)，必須是防水式構(gòu)造，輸出軸的最小直徑為25mm。
Total weight of DC Gear Motor must be 17lbs or less. DC motor is 8lbs. Attaches to approved DC motor that weighs about 8lbs with brake.
直流齒輪電機(jī)的總重量為171磅或者更輕。直流電機(jī)是8磅，8磅的直流電機(jī)加上制動(dòng)器Mounts to 83% efficient DC motor電機(jī)功率達(dá)到83%
Used in portable transportion equipment用于輕便型交通設(shè)備
>90% efficiency is required要求功率>90%
240W DC motor with 12VDC @ 20A 輸出直流電壓12V@輸出電流20A，直流電機(jī)功率240W
Continuous is 196W x 150:1 ratio (estimated ratio of gear reducer)
連續(xù)功率為196W x 150:1減速比（預(yù)計(jì)齒輪減速器的減速比）

非常低的工作循環(huán)，一天僅使用15分鐘，至少30-分鐘的間歇期。
Used at most 60 hours per year
一年最多使用60小時(shí)
Used in outdoor application, IP66 or sealed
用于戶外裝置，達(dá)到IP66防塵防水等級(jí)或者密封。
Total DC gear motor package is less than 17 lbs.
總的直流齒輪電機(jī)組合不超過(guò)17磅
DC brake motor weighs about 8 lbs, so gear reducer weighs about 10lbs
直流制動(dòng)電機(jī)重8磅，所以齒輪減速器約重10磅
We do not care if the reducer is in-line or right angle, We do not care if reducer is planetary, helical, parallel in-line, hypoid or other style gear reducer. Only needs to meet efficiency and weight requirements. We would prefer an aluminum housing for environmental concerns.
減速器是平行軸還是直交軸無(wú)關(guān)緊要，減速器是行星型，斜齒輪型，平行直列型，斜齒圓柱型或其他類型的齒輪減速器對(duì)我們來(lái)說(shuō)都無(wú)所謂，只要能滿足功率及重量的要求就可以。處于環(huán)保要求考慮我們更傾向于選擇鋁外殼。
