Abstract
The utility model relates to a transmission mechanism, in particular to a rotating screw rod transmission mechanism which comprises a ladder-shaped screw rod and is characterized in that an upper thrust shaft shoulder is arranged at the upper end of the ladder-shaped screw rod, a speed reducing motor is fixed on the top portion of the upper thrust shaft shoulder, a lower thrust shaft shoulder is arranged at the lower end of the ladder-shaped screw rod, and the lower thrust shaft shoulder is fixed on a rolling ball type thrust bearing. The rotating screw rod transmission mechanism has the advantages of being simple in structure and good in screw rod rigidity, moving vertically is avoided, deformation cannot happen easily, operation is smooth, and the rotating screw rod transmission mechanism is suitable for wide popularization.
Description
(1) technical field
The utility model relates to driving mechanism, particularly a kind of rotary screw rod driving mechanism.
(2) background technique
Lead screw transmission mechanism is mainly used to be transformed to rotatablely moving straight line motion, or straight line motion is converted into rotatablely moves, lead screw transmission mechanism mainly is divided into two kinds, and a kind of is that screw mandrel moves up and down but do not rotate, and another kind is that screw mandrel rotates, driving gate by nut moves up and down, the surface friction drag of the first driving mechanism is larger, and transmission efficiency is low, and the precision of the second driving mechanism is higher, system stiffness is good, the utility model article the second mechanism.
(3) summary of the invention
The utility model provides a kind of compact structure in order to remedy the deficiencies in the prior art, the rotary screw rod driving mechanism of stable working.
The utility model is achieved by the following technical solution:
A kind of rotary screw rod driving mechanism comprises trapezoidal screw, it is characterized in that: described trapezoidal screw upper end is equipped with the thrust shaft shoulder, and upper thrust shaft shoulder top is fixed with reducing motor; The trapezoidal screw lower end is equipped with the lower thrust shaft shoulder, and the lower thrust shaft shoulder is fixed on the ball type thrust-bearing.
The beneficial effects of the utility model are: the rotary screw rod driving mechanism of this model utility is simple in structure, and the screw mandrel good rigidly can not move up and down, and is not yielding, and moves smoothly, is suitable for extensive popularization.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
Among the figure, 1 trapezoidal screw, the thrust shaft shoulder on 2,3 reducing motors, 4 times thrust shaft shoulders, 5 ball type thrust-bearings.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises trapezoidal screw 1, it is characterized in that: described trapezoidal screw 1 upper end is equipped with the thrust shaft shoulder 2, and the upper thrust shaft shoulder 2 tops are fixed with reducing motor 3; Trapezoidal screw 1 lower end is equipped with the lower thrust shaft shoulder 4, and the lower thrust shaft shoulder 4 is fixed on the ball type thrust-bearing 5.
Adopt rotary screw rod driving mechanism of the present utility model, the upper thrust shaft shoulder 2 of trapezoidal screw 1 upper end withstands the reducing motor 3 at top, can prop up like this trapezoidal screw 1 moves up, the lower thrust shaft shoulder 4 of trapezoidal screw 1 lower end is fixed on the ball type thrust-bearing 6, support the downward load of trapezoidal screw 1, trapezoidal screw 1 two ends can be fixed like this, can not move up and down, strengthened the rigidity of trapezoidal screw 1, made operation more smooth and easy.
Claims (1)
1. a rotary screw rod driving mechanism comprises trapezoidal screw (1), it is characterized in that: described trapezoidal screw (1) upper end is equipped with the thrust shaft shoulder (2), and the upper thrust shaft shoulder (2) top is fixed with reducing motor (3); Trapezoidal screw (1) lower end is equipped with the lower thrust shaft shoulder (4), and the lower thrust shaft shoulder (4) is fixed on the ball type thrust-bearing (5).
