Description
Technical field
The present invention relates to the mechanical transmission structure of antenna rotating platform, especially gear sub-center away from and return difference adjustment technology.
Background technique
Antenna rotating platform be generally driven by a motor retarder, retarder output shaft band pinion gear, drive again final stage gear wheel,
To drive antenna load to rotate.Gear pair usually has certain return difference.The return difference of gear pair has significant impact to equipment performance,
Equipment precision can be reduced, and may cause oscillation and additional noise, it usually needs return difference is controlled.
Return difference between the pinion gear and final stage gear wheel of reducer output shaft connection is usually adjusted with eccentric bushing.Generally
Eccentric bushing tune center away from and the principle of return difference be with method: the positioning spigot of retarder is passed through into the through-hole on eccentric bushing, it is eccentric
Set is processed into (retarder mounting hole and pedestal mounting hole are not pre-machined) as shown in Figure 1 and Figure 2, due to eccentric bushing through-hole and partially
The decentraction of heart loop port excircle (because eccentric degree is little, does not see that through-hole is bright less than 1mm in actual production, therefore on figure
The aobvious side for being biased to eccentric loop port), therefore rotating eccentricity covers the center of adjustable pinion gear and gear wheel away from adjustment in turn
Return difference between the two makes return difference between pinion gear and final stage gear wheel reach specified requirement when rotating eccentricity is set to a certain position
Afterwards, the relative position for subtracting eccentric bushing and pedestal is just write down, while the motor on retarder is rotated into assigned direction, writes down deceleration
Then retarder mounting hole and pedestal mounting hole are stamped in the relative position of device and eccentric bushing on eccentric bushing, complete assembly.
This mode has the disadvantage that inconvenient for operation, and inefficient, mounting hole is not easy to guarantee with beating quality；If thing
First retarder mounting hole is accomplished fluently, then after completing installation, retarder and motor direction may be arbitrarily, and then block or
Interfere peripheral structure.
Summary of the invention
In order to solve the above-mentioned technical problem, the present invention improves eccentric bushing, provides a kind of new antenna rotating platform
And eccentric bushing.
Antenna rotating platform provided by the invention, including motor, retarder, eccentric bushing, pinion gear, gear wheel and pedestal；It is described
Eccentric bushing is fixed on the pedestal, and motor is connect to drive retarder to rotate with retarder, and reducer output shaft passes through bias
The through-hole of set is connect with pinion gear, and the positioning spigot of retarder is socketed in the through-hole of eccentric bushing, and pinion gear is nibbled with gear wheel
It closes；Wherein eccentric bushing includes bottom plate and the seam allowance from bottom plate protrusion, and the through-hole of eccentric bushing is located in eccentric loop port and eccentric
The through-hole of set and eccentric loop port excircle decentraction；Two circle mounting holes are provided on eccentric bushing, outer ring mounting hole is uniformly distributed,
It is distributed circle and eccentric loop port excircle is concentric, corresponding for eccentric bushing to be installed on pedestal, is provided on pedestal partially
The heart covers mounting hole；Inner ring mounting hole is uniformly distributed, and distribution circle is concentric with eccentric bushing through-hole, for retarder to be fixed on bias
It puts on.
Further, several notches are offered in bottom plate outer edge.
Further, the excircle of eccentric bushing bottom plate and eccentric loop port excircle are concentric.
The present invention also provides a kind of eccentric bushing for antenna rotating platform, including bottom plate and from the seam allowance of bottom plate protrusion,
The through-hole of eccentric bushing is located in eccentric loop port and the through-hole of eccentric bushing and eccentric loop port excircle decentraction；It is set on eccentric bushing
Two circle mounting holes are equipped with, outer ring mounting hole is uniformly distributed, and distribution is round concentric with eccentric loop port excircle, is used for eccentric bushing
It is installed on pedestal；Inner ring mounting hole is uniformly distributed, and distribution circle is concentric with eccentric bushing through-hole, for retarder to be fixed on partially
The heart is put on.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
The present invention offers two circle mounting holes on eccentric bushing, and each mounting hole is uniformly distributed circumferentially, beats on pedestal
There is eccentric bushing mounting hole, adjust the density and spacing of mounting hole, can find after the return difference of big pinion gear mixes up
Two pairs of retarder mounting holes and pedestal mounting hole fix eccentric bushing, while the direction of retarder and motor being made not interfere week
Side object.Without beating mounting hole again after adjusting eccentric bushing position, so that adjustment operation becomes simple, improves adjustment efficiency；
It also avoids being not easy the problems such as guaranteeing with inconvenient for operation, quality when beating.
