The utility model transmission explanation: stir speed reducer and imported by primary centre wheel 12, slow down through one-level, drive secondary center wheel 8 by primary planet carrier 11, enter double reduction.Through double reduction, drive tertiary centre wheel 4 by secondary planet frame 7, enter three grades of decelerations.Third level reducing gear is output member with third-level planetary frame 3, and third-level planetary frame 3 drives output flange 1 by drum type land 2, and output flange 1 drives cylinder and rotates, and realizes complete machine output.
Stressed explanation: output flange 1 and drum type land 2 are fixed together, and under base housing 23 and 24 effects of big bearing, under static state what drive part are not produced thrust; Under the motion state, between output flange 1 and the third-level planetary frame 3, there is relative movement between drum type land 2 and the third-level planetary frame 3, two joint pairs are sphere, do not produce thrust in theory, but because there are error in processing and assembling, can produce certain thrust and thrust can be to three grades of drive part transmission.Three grades of drive parts float and the installation of tilting, and deadweight can produce one and point to the axial thrust load that secondary is set out part; Because the existence of backlash, machining error, assembly error also can produce an axial force of pointing to the secondary drive part in rotating process; After synthesizing, superpose, two power pass to the secondary drive part; Tertiary centre wheel 4 is axial limiting spare, and power can be by the tertiary centre wheel to the previous stage transmission.In like manner: the secondary center wheel is axial limiting spare,
Just take turns 8 to front transfer by secondary center in the power of tertiary centre wheel 4 accumulations and the power of secondary drive part generation; The primary centre wheel is axial limiting spare, and the power of 8 power of accumulating and the moving part generation of one-level of taking turns at secondary center just takes turns 12 to front transfer by primary centre.Shaft block ring 16, bearing I 15, hole are carried out axial limiting with 14 pairs of primary centre wheels 12 of back-up ring, and the power of the accumulation on the primary centre wheel 12 are delivered on the speed reducer shell.
In sum: stir in the speed reducer, between third-level planetary frame 3 and tertiary centre wheel 4, between tertiary centre wheel 4 and secondary center wheel 8, between secondary center wheel 8 and primary centre wheel 12, exist axial force and speed difference.Particularly between secondary center wheel 8 and the primary centre wheel 12, primary centre wheel 8 bears end at last as high speed input end and axial force, between secondary center wheel and the primary centre wheel bigger axial force and and speed difference is arranged.In common multistage planet driving mechanism, be to allow the direct phase mutual friction of two-stage central gear end face, and in the facing cut Sump lubrication of phase mutual friction, this mounting type is the most commonly used in the speed reducer of horizontal positioned.After band carries, stir that speed reducer is smoldered soon and noise is bigger, it is serious to find opening and inspecting after that primary centre wheel and secondary center are taken turns the contact jaw surface wear, and sintering, phenomenon such as turn blue; The secondary center wheel is more serious with two end wears that the tertiary centre wheel contacts; Two end faces that tertiary centre wheel and third-level planetary bridge joint touch have mild wear.In order to overcome the above problems, between central gears at different levels, bearing apical axis and bearing means have been increased, experiment shows, the utility model efficiently solves the stressed big and more serious problem of frictional ratio that stirs between the speed reducer central gears at different levels, effectively prevent the end wear that contacts between the central gears at different levels, make stir speed reducer rotate safety, steadily and noise lower.
