Abstract
The utility model relates to a harmonic speed reducer transmission device adopting a harmonic gear reducing transmission. The utility model can drive a supported object to rotate horizontally and vertically. Owing to the single characteristic of a harmonic speed reducer, the utility model can make the high rotation speed of a motor reduced to very low rotation speed. As a consequence, the supported object has stable rotation, small noise and uniform speed movement. Meanwhile, the device has the advantages of small size, light weight and no return difference. Therefore, the utility model is an ideal transmission device.
Description
The utility model belongs to a kind of improvement of the slewing gear that slows down.
At present, the deceleration slewing gear that adopts the control motor to control because control rotating speed of motor height generally all is to utilize many group spur wheels to cooperate to slow down, obtains the required slow-speed of revolution, controls controlled thing again and makes controlled rotation.This deceleration slewing gear volume is bigger, and to installation and processing required precision height, thereby cost is higher; Vibration is big in the deceleration rotation process, noise is big, return difference is big, control accuracy is low.
The purpose of this utility model provides that a kind of vibration, noise, return difference are little, the high volume of control accuracy, the corresponding novel deceleration slewing gear that reduces of weight.
The utility model adopts harmonic speed reducer directly to be connected with the control electric machine main shaft, replaces many group spur wheels and cooperates, and slows down.Cooperate with multiple spur wheel and to compare, the harmonic speed reducer volume is little, and is in light weight, vibrates for a short time, and noise is low, return difference is little, control accuracy is high, has stronger bearing capacity.After adopting harmonic speed reducer, the performance of deceleration slewing gear is significantly improved.The harmonic speed reducer output shaft according to actual needs, also can with spur wheel, worm gear or worm screw connect, and are used.
Accompanying drawing is the side-looking and the front elevational schematic of one of the utility model most preferred embodiment, is made up of vertical surface rotation system and horizontal plane rotation system two-part.
In the vertical surface rotation system, control motor (5) is fixed on the side plate (7), the main shaft of control motor (5) is connected with the input shaft of harmonic speed reducer (3), the output shaft of harmonic speed reducer (3) connects worm screw (1), worm screw (1) and worm gear (9) engagement, be fixed with supporting plate (2) on the output shaft of worm gear (9), the fixing controlled thing of supporting plate (2) carrying (as vidicon camera etc.).By start-up control motor (5), can make controlled thing that supporting plate (2) and it fixes together, be the axle center with worm gear (9) output shaft, in vertical surface, rotate, change the angle of depression or the elevation angle of controlled thing.
In the horizontal plane rotation system, control motor (4) is fixed on the base plate (8), the main shaft of control motor (4) is connected with the input shaft of harmonic wave rotating speed device (6), the output shaft of harmonic speed reducer (6) is fixed with spur wheel (11), spur wheel (11) is meshed with spur wheel (10), and spur wheel (10) is fixed on the support or supporting surface of deceleration slewing gear by its central shaft hole.By start-up control motor (4), can make the deceleration slewing gear, be the axle center with the central shaft hole of spur wheel (10), in horizontal plane, rotate, change the horizontal azimuth of controlled thing.
Control motor (4) and (5) can start work respectively, also can start work simultaneously, makes controlled thing carry out the adjustment at horizontal azimuth and the vertical surface angle of depression or the elevation angle, remote control easy to implement respectively or simultaneously.
