Abstract
The utility model discloses a novel reduction box mechanism, relates to the field of machine manufacturing engineering and in particular relates to a novel reduction box mechanism. The novel reduction box mechanism is composed of a shifting fork (1), a tooth-shaped wheel (2), a spring (3), a worm wheel (4), a long shaft (5), a shaft pin (6) and a worm (7), wherein the shifting fork (1) is arranged at the upper end of the long shaft (5); the tooth-shaped wheel (2) arranged at right ends of the worm wheel (4) and the spring (3); the worm wheel (4) is externally arranged on the long shaft (5) and connected with the worm (7); the long shaft (5) is arranged inside the tooth-shaped wheel (2) and the worm wheel (4); the shaft pin (6) is arranged between the spring (3) and the shifting fork (1); and the lower end of the worm (7) is connected with the upper end of the worm wheel (4). By adopting the mechanism, the power transmission and the driving of a reduction box are realized through tooth meshing, therefore, the phenomenon of slipping does not happen and the work stability of the reduction box is guaranteed.
Description
Technical field:
The utility model relates to the mechanical manufacturing engineering field, a kind of Novel speed-reducing draw box mechanism of specific design.
Background technique:
Most reducing gears all are the purpose that reaches transmission of power by the friction engagement between two friction members usually in the market, the drawback that adopts this mechanism is exactly easily to skid between two, the situation that the stopping time turns during appearance, thus the operation of speed reducer affected.
The model utility content:
The purpose of this utility model provides a kind of Novel speed-reducing draw box mechanism, and it can effectively solve the existing problem of background technique, the phenomenon that can not occur skidding.
For solve the existing problem the utility model of background technique be by the following technical programs with to realize: it is comprised of fork 1, thread form wheel 2, spring 3, turbine 4, major axis 5, pivot pin 6, worm screw 7, fork 1 is installed in the upper end of major axis 5, thread form wheel 2 is installed in the right-hand member of turbine 4 and spring 3, turbine 4 is arranged on the outer top of major axis 5 and is connected with worm screw 7, major axis 5 is arranged on the inside of thread form wheel 2 and turbine 4, pivot pin 6 is arranged on the centre of spring 3 and fork 1, and the lower end of worm screw 7 is connected with the upper end of turbine 4.Shift fork 1 compresses thread form wheel 2 left under inner effect, to be in engagement between thread form wheel 2 and worm gear, dynamic system is by belt and band wheel drive worm screw 7, worm screw 7 and worm gear 4 engagements drive turbine 4, drive thread form wheel 2 by worm gear 4 and 2 engagements of thread form wheel again, connect by pivot pin 6 between thread form wheel 2 and the major axis 5, drive major axis 6 and rotate, under this state, spring 3 is in compressive state.When unclamping, shift fork 1 has not had reverse torsion, the elastic force of compressed spring 3 bounce-back when mediate this moment, force thread form wheel 2 to be moved to the left, force thread form to be taken turns and worm gear 4 disengaging engagements, thread form wheel 2 and worm gear 4 disengagings cause turbine 4 to dally on the major axis 5, can not reach the effect of driving major axis 5.Adopting speed reducer after this mechanism is that engagement by profile of tooth comes transferring power and driving, thus the phenomenon that can not occur skidding, thus guaranteed the stability of speed reducer work.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in Figure 1, this embodiment is comprised of fork 1, thread form wheel 2, spring 3, turbine 4, major axis 5, pivot pin 6, worm screw 7, fork 1 is installed in the upper end of major axis 5, thread form wheel 2 is installed in the right-hand member of turbine 4 and spring 3, turbine 4 is arranged on the outer top of major axis 5 and is connected with worm screw 7, major axis 5 is arranged on the inside of thread form wheel 2 and turbine 4, and pivot pin 6 is arranged on the centre of spring 3 and fork 1, and the lower end of worm screw 7 is connected with the upper end of turbine 4.Shift fork 1 compresses thread form wheel 2 left under inner effect, to be in engagement between thread form wheel 2 and worm gear, dynamic system is by belt and band wheel drive worm screw 7, worm screw 7 and worm gear 4 engagements drive turbine 4, drive thread form wheel 2 by worm gear 4 and 2 engagements of thread form wheel again, connect by pivot pin 6 between thread form wheel 2 and the major axis 5, drive major axis 6 and rotate, under this state, spring 3 is in compressive state.When unclamping, shift fork 1 has not had reverse torsion, the elastic force of compressed spring 3 bounce-back when mediate this moment, force thread form wheel 2 to be moved to the left, force thread form to be taken turns and worm gear 4 disengaging engagements, thread form wheel 2 and worm gear 4 disengagings cause turbine 4 to dally on the major axis 5, can not reach the effect of driving major axis 5.Adopting speed reducer after this mechanism is that engagement by profile of tooth comes transferring power and driving, thus the phenomenon that can not occur skidding, thus guaranteed the stability of speed reducer work.
