Abstract
The utility model relates to a transmission applied to high-precision rotation. The transmission disclosed by the utility model comprises a box body; a roller plate is arranged in the box body; a fixed bracket is arranged at the side wall of the box body; the roller plate is arranged on a rotation shaft; a plurality of cylindrical rollers are radially distributed on the circumference of the end face of the roller plate; the roller plate is meshed with a worm rod via the cylindrical rollers; two ends of the worm rod are fixed in the box body via bearings; and a driving shaft of the worm rod is connected with a motor via a coupler. The transmission applied to the high-precision rotation, disclosed by the utility model, is simple in structure, achieves the continuous or intermittent indexing through the meshing between the roller plate and the worm rod, is long in service life and can conveniently fix the box body via the fixed bracket; and due to the long service life, the transmission disclosed by the utility model can replace an indexing mechanism.
Description
Technical field
The utility model relates to a kind of speed changer that is applicable to high-precision rotary.
Background technique
Present development along with precision processing technology, needs for speed changer are also increasing, but existing speed changer structure is all generally to adopt gear-shift transmission, turbine and worm screw are also the speed changer structures that often has, existing speed changer structure can only slow down, and can not realize calibration, particularly can not realize continuously and interrupted division, in highi degree of accuracy processing, need to realize continuously or the speed changer that is applicable to high-precision rotary of interrupted division.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of speed changer that is applicable to high-precision rotary simple in structure, easy to use.
The speed changer that is applicable to high-precision rotary of the present utility model, comprise casing, the inside of described casing is provided with the roller dish, the sidewall of casing is provided with fixed support, the roller dish is arranged on rotatingshaft, is radially distributed with some cylindrical rollers on the end face circumference of roller dish, and the roller dish is by the cylindrical roller engages worm, the two ends of worm screw are fixed on box house by bearing, and the live axle of worm screw connects motor by coupling.
Compared with prior art the beneficial effects of the utility model are: the speed changer structure that is applicable to high-precision rotary of the present utility model is simple, engagement by roller dish and worm screw, realize continuous or calibration intermittently, long service life, can easily casing be fixed by fixed support, long service life can replace indexing mechanism.
Description of drawings
Fig. 1 is the described a kind of structural representation that is applicable to the speed changer of high-precision rotary of the utility model embodiment.
In figure:
1, casing; 2, roller dish; 3, fixed support; 4, cylindrical roller; 5, worm screw; 6, bearing; 7, live axle; 8, coupling; 9, motor.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of speed changer that is applicable to high-precision rotary, comprise casing 1, the inside of described casing 1 is provided with roller dish 2, and the sidewall of casing 1 is provided with fixed support 3, and roller dish 2 is arranged on rotatingshaft, be radially distributed with some cylindrical rollers 4 on the end face circumference of roller dish 2, roller dish 2 is by cylindrical roller 4 engages worm 5, and the two ends of worm screw 5 are fixed on casing 1 inside by bearing 6, and the live axle 7 of worm screw 5 connects motors 9 by coupling 8.
The speed changer structure that is applicable to high-precision rotary of the present utility model is simple, by the engagement of roller dish and worm screw, realizes continuously or calibration intermittently, long service life, can easily casing be fixed by fixed support, long service life can replace indexing mechanism.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
