Abstract
The utility model relates to a gear transmission structure, which comprises a motor (1), a pinion (2), a large annular gear ring (3) and three brackets (5), wherein the motor (1) is connected with the pinion (2); the pinion (2) is meshed with the outer wall of the large annular gear ring (3); each bracket (5) is provided with small roller (4); the three small rollers (4) are distributed uniformly along the circumference of the large annular gear ring (3) ; the small rollers (4) are matched with the inner flange (3.1) of the large annular gear ring (3). According to the gear transmission structure disclosed by the utility model, the pinion connected with the motor is used for driving the large annular gear ring, so that a test tube frame fixed on the large annular gear ring is driven to rotate; the three small rollers are uniformly and circumferentially distributed on an equal-height horizontal plane, so that the large annular gear and the test tube frame are fixed together.
Description
Technical field
The utility model relates to a kind of gear transmission structure, be used to the immunology detection instrument of transfusing blood, belongs to the medical equipment technical field.
Background technique
The existing cuvette cartridge mounted mechanism that adopts rotation plate type, by the small gear on motor shaft, drive large annular tooth ring, to reach, test tube holder fixed thereon is rotated, adopt this kind structure small gear and large annular tooth ring to skid sometimes to cause and do not mesh, affected the normal use of instrument.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of rotating property stable gear transmission structure.
The purpose of this utility model is achieved in that
A kind of gear transmission structure, comprise motor, small gear and large annular tooth ring, described motor is connected with small gear, the outer wall engagement of the large annular tooth ring of small gear, be characterized in: described structure also comprises three supports, on described each support, be provided with a trundle, described three trundles distribute along large annular tooth ring even circumferential, and trundle coordinates with the inward flange of large annular tooth ring.
A kind of gear transmission structure of the utility model, its trundle adopt Rubber materials to make.
A kind of gear transmission structure of the utility model, sliding motion structure is adopted in the upper end of one of them support.
Compared with prior art, the beneficial effects of the utility model are:
A kind of gear transmission structure of the utility model, by the small gear be connected with motor, drive large annular tooth ring, the test tube holder that makes to be fixed on large annular tooth ring rotates, adopting three trundles on contour horizontal plane, to press even circumferential distributes, large annular tooth ring and test tube holder are fixed, trundle adopts Rubber materials to make, can increase the frictional force with large annular tooth ring inward flange, while preventing from rolling, skid, and can effectively reduce vibrations and reduce noise, sliding motion structure is adopted in three one of them upper ends of support, with civilian dress, tear large annular tooth ring and test tube holder open, and can in assembling, regulate the tightness of test tube holder rotation according to actual conditions, therefore can guarantee the normal use of instrument.
