Description
【Technical field】
The present invention relates to cycloid reduction technical field, more particularly, it relates to a kind of general cycloid of zero return difference of interlayer casing
Reduction box.
【Background technology】
Prior art B, X Series Universal cycloid speed reducer, existing nearly 50 years production histories, product is throughout many departments.
Prior art major defect is：
(1) thermal power is not high：Not device fan and scattered using other on domestic B, X series cycloid speed reducer high speed shaft
Hot measure, only relying on natural heat dissipation causes thermal power low so that user's one, two types number of increasing of having to carry out type selecting, perhaps
Many mechanical theory monographs are exactly so to specify, its result necessarily increases expense, and power is bigger, expense increase is more：Such as volume
Fixed 8255 types (2.68 ten thousand yuan of weight 865kg, valency), now increase type selection 8265 (weight 1125kg, a valency 3.82 ten thousand
Unit)；Two type selections 8270 (6.22 ten thousand yuan of weight 2610kg, valency) are increased such as.
《Gear Transmission Design handbook》Page 972 are pointed out：Thermal power is enclosed decelerator under lubricating oil balanced temperature conditions
Caned peak power continuously transmitted.Thermal power should be equal to or be bordering on the power of real work transmission.
《The design of Planetary Involute Gear and manufacture》Page 230 are pointed out：Thermal power is referred under the conditions of natural cooling
Lubricating oil temperature is less than input power during allowable temperature.Thermal power be design lubricating system, from the important evidence of decelerator.
The defect low to solve prior art thermal power, present invention aim at providing with water-cooled or air-cooled in casing interlayer
Substitute natural heat dissipation to improve thermal power.
(2) general cycloidal reducer return difference is big (10 '～15 '), the above-mentioned advantage of general cycloid reduction technology is used
Make large solar photovoltaic generating tracking drive device, it is impossible to as bearing turntable for radar antenna driving means.
Solar energy power generating tracking drive device, technical scheme both domestic and external are " multistage planet deceleration components+worm gear snail
Bar pair+worm anti-backlash mechanism ", mainly problem appear to is that in operation：Worm couple is larger as output stage volume, axial force
Greatly, longtime running occurs that abrasion, return difference increase and impact positioning precision significantly.Chongqing gear-box disclosed in Patent Office of the People's Republic of China
The patent application of company《A kind of azimuth transmission device of heliostat》(201310115194.5), its technical scheme is " series of rows
Star deceleration component+worm couple+planet output block+planet anti-backlash mechanism ", is disadvantageous in that：Complex structure；Due to row
Star anti-backlash mechanism and the long half of ring gear tooth in making planet output block are engaged with planetary gear, and second half and the gap planetary gear that disappears
Engagement, thus bearing capacity reduces half.
《Radar and antagonism》2004.02 disclosed in the phase《A kind of brand-new bearing turntable for radar antenna》, it is by one " external three
The azimuth drive that crank planetary speed reducer with small tooth number difference " is directly constituted, is disadvantageous in that：Realized with the high accuracy of manufacture little
Return difference, thus manufacturing cost is considerably increased, Involute Small Teeth Difference Planetary Gearing bearing capacity and efficiency are less than cyclo drive.
【The content of the invention】
