Description
Technical field
The utility model relates to technical field of automation equipment, more particularly to a kind of hollow rotating platform.
Background technique
Chinese utility model patent discloses a kind of hollow rotating micro regulator for platform, application number:
CN201820142655.6, open (bulletin) day: 2018-10-19 comprising: cabinet, connecting flange and counter flange, cabinet
Inside is equipped with outer gear ring, and connecting flange and counter flange are connected to the lower section of cabinet side, connecting flange and transition method in turn
The blue internal input shaft that is equipped with realizes power transmitting, and one end that input shaft upwardly extends has driving gear, also sets on cabinet
It is equipped with a fine tuning structure, fine tuning structure includes a flush end holding screw, and flush end holding screw is screwed on the side end face of cabinet, is revolved
Turning flush end holding screw drives connecting flange and input shaft integrally to advance, come adjust the center of outer gear ring and driving gear away from.It is logical
Aforesaid way is crossed, the utility model hollow rotating micro regulator for platform is adjusted using rotary screw between the engagement of internal gear
Gap, structure is simple, easy to operate, while the engagement of internal gear can be made to reach zero clearance, improves positioning accuracy, reduces
Processing and manufacturing cost.
The rotating platform micromatic setting adjusts the back lash of internal gear, this screw adjusting side using rotary screw
The shortcomings that formula are as follows: 1, when being adjusted using screw, the method for adjustment of back lash is to turn adjusting nut, to change driving gear
Position.And gear teeth meshing gap should be within the scope of 0.15~0.40mm.If gap is greater than specified value, driven wheel of differential should be made close
Drive bevel gear, it is on the contrary then leave.To adjust back lash, the circle number that one end adjusting nut is screwed into should be equal to the other end and adjust
The circle number that nut is back-outed.It can be seen that the adjusting nut for not only needing to twist one end when adjusting from above-mentioned regulative mode, and
And the adjusting nut for twisting the other end is also needed just to can guarantee the position of driven wheel of differential, adjusting is very troublesome, needs both sides simultaneously
Operation；2, degree of regulation is low, and since the prior art is adjusted using screw, adjusting when will constantly listen the gear engagement to be
No there are also noises, just prove to adjust in place when only the noise when gear engages reaches normal sound；And adjust essence
Spend it is low because can not know when rotating nuts rotation every time turn around back lash can adjust how much, adjusting when is
Adjusting is realized by manual rotating nuts, needs operator by one approximate dimensions of adjusting are felt, then using multiple tune
Section ability mode is suitably sized to one, is unable to fast debugging to the smallest size of back lash error, existing screw tune
Regulating device needs operator to have technical experience abundant and certain debug time back lash could be adjusted in place, when not having
When the people of technical experience abundant is adjusted, not only adjustment speed is slow, it is also necessary to which repeated multiple times adjusting is just adjustable in place.
