Abstract
The utility model relates to a play to put in a position rotation mechanism, including casing, worm wheel, worm, sun gear, two sets of planet wheel and two sets of slewing bearing, the worm is rotated with the casing and is connected worm wheel and sun gear fixed connection to with worm mesh, sun gear and casing rotate to be connected, and two sets of planets wheel is located the sun gear both sides respectively, all mesh with the sun gear, two sets of slewing bearing respectively with respective planetary gear meshing. The utility model discloses compact structure, installation space is little.
Description
Technical field
The utility model relates to a kind of swing type mechanism of elevator machinery.
Background technology
Existing elevator machinery operationally, often need the parallel motion simultaneously carrying out suspension hook, the parallel motion of self-balanced upper rotary and the rotary motion of arm, this process must steadily be carried out, and to affect its stability most important be exactly the rotary motion of arm opposite brackets; This rotary motion is generally realized by swing type mechanism, what swing type mechanism was common is bearing arrangement, namely there is the part of rotation and fixing part, existing swing type mechanism is in order to realize the smooth running of tower crane, increasing often by the size design of swing type mechanism, this design makes swing type mechanism self conduct oneself with dignity to be increased, and make the pressure of weighing of tower crane support excessive, structure is not compact.
Summary of the invention
The purpose of this utility model is to provide a kind of compact conformation, and swing type mechanism is reused in little the rising of installing space.
In order to achieve the above object, the technical solution of the utility model is: a kind of rising reuses swing type mechanism, comprise housing, worm gear, worm screw, sun wheel, two groups of satellite gears and two groups of pivoting supports, described worm screw is connected with housing into rotation, and worm gear is fixedly connected with sun wheel, and and worm mesh, sun wheel is connected with housing into rotation, two groups of satellite gears lay respectively at sun wheel both sides, all engage with sun wheel, and two groups of pivoting supports engage with respective satellite gear respectively.
Also be provided with bracing frame in described housing, one end and the bracing frame of sun wheel are rotationally connected by clutch shaft bearing.
Also be provided with erecting frame in described housing, two groups of satellite gears are all rotationally connected by rotating shaft and erecting frame.
The two ends of described worm screw are equipped with handle.
Described handle is provided with the assister bar of L shape.
After adopting said structure, when the utility model runs, by the rotation of worm screw, drive worm gear wheel, drive sun wheel to rotate simultaneously, sun wheel drives two groups of satellite gears to rotate, and satellite gear drives respective pivoting support, thus drives arm to rotate.The utility model coordinates owing to adopting worm and gear, and coordinates two groups of satellite gears and two groups of pivoting supports, and make compact conformation of the present utility model, installing space is little.
Accompanying drawing explanation
Fig. 1 is structure cutaway view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is structure birds-eye view of the present utility model.
Detailed description of the invention
The embodiment provided below in conjunction with accompanying drawing is described in further detail the utility model.
Shown in Fig. 1,2,3, a kind of rising reuses swing type mechanism, comprise housing 1, worm gear 2, worm screw 3, sun wheel 4, two groups of satellite gears 5 and two groups of pivoting supports 6, described worm screw 3 is rotationally connected with housing 1, and worm gear 2 is fixedly connected with sun wheel 4, and engages with worm screw 3, sun wheel 4 and housing 1 are rotationally connected, two groups of satellite gears 5 lay respectively at sun wheel 4 both sides, all engage with sun wheel 4, and two groups of pivoting supports 6 engage with respective satellite gear 5 respectively.
Shown in Figure 2, in order to make sun wheel 4 install firmly, rotate reliable, be also provided with bracing frame 1-1 in described housing 1, one end and the bracing frame 1-1 of sun wheel 4 are rotationally connected by bearing 10.
Shown in Figure 2, in order to make the rotating shaft 5-1 of two groups of satellite gears 5 install firmly, be also provided with erecting frame 1-2 in described housing 1, two groups of satellite gears 5 are all rotationally connected by rotating shaft 5-1 and erecting frame 1-2.
Shown in Figure 1, in order to can very labour-saving rotary worm 3, the two ends of described worm screw 3 be equipped with handle 7, and described handle 7 is provided with the assister bar 8 of L shape.
Shown in Fig. 1,2, when the utility model uses, driven the rotation of worm screw 3 by turning handle 7, worm screw 3 drives worm gear 2 to rotate, and drive sun wheel 4 to rotate, sun wheel 4 drives two groups of satellite gears 5 to rotate simultaneously, satellite gear 5 drives respective pivoting support 6, thus drives arm to rotate.The utility model coordinates owing to adopting worm gear 2 and worm screw 3, and coordinates two groups of satellite gears 5 and two groups of pivoting supports 6, and make compact conformation of the present utility model, installing space is little.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
