Abstract
The utility model discloses a big quartzy clock movement drive mechanism for modified building. It is mainly characterized by that the step motor is directly and rigidly connected with worm, so that the worm-gear pair structure is changed from the last-stage speed reduction of existent machine core minute shaft to first-stage speed reduction, and its original three-stage speed reduction is changed into second-stage speed reduction, and all the connecting wheels are removed, so that its structure is greatly simplified, its weight and cost are reduced by about half, its working stability is raised, and its noise is reduced to below 30 db.
Description
The utility model relates to a kind of improved timing gear train, particularly a kind of quartzy great bell movement gear train for building.
Present quartzy great bell movement gear train for building, be directly to drive the transmission of secondary straight-tooth gear by stepper motor, then final stage is the worm gear pair reducing gear, drives minute hand shaft and rotates, the last differential motion that realizes 12:1 again through secondary straight-tooth gear speed change drive hour hand axle cover.This gear train exists weak point to be: because of preceding double reduction is the straight-tooth gear transmission, and stepper motor is high-frequency power source, because rotating speed is fast, all there is certain clearance in the straight-tooth that respectively is meshed, produce high-frequency bump during running, stable working is poor, and noise is big.Adding worm gear pair is the afterbody that is contained in minute hand shaft, and minute hand shaft rotation will be through three grades of decelerations, thus volume greatly, complex structure, the cost height.
The purpose of this utility model just provides a kind of improved big clock movement gear train, reaches stable working, and noise is little, for building quartzy great bell movement gear train that the little cost of volume is low.
Task of the present utility model is done in such a manner: the direct and worm screw rigid attachment of stepper motor, be installed in underpart and drive the transmission of worm gear speed change, make the worm gear pair structure become minute hand shaft chopped-off head reduction gear, because the worm-drive speed ratio is big, after speed is reduced, through the transmission of one-level straight-tooth gear, realize the requirement of minute hand shaft rotating speed again.The hour hands axle sleeve again through the straight-tooth speed change, is realized the differential motion of 12:1.Because worm gear pair is the motion of a kind of screw inclined plane, become the big defective of impact noise when overcoming former secondary straight-tooth transmission after the chopped-off head transmission, also improved the stationarity of work greatly.Because minute hand shaft changes secondary into by former three grades of decelerations, and removes all cock wheels, simplifies the structure, and has reduced volume and weight.
Below with reference to drawings and Examples the utility model is described in detail.
Fig. 1 is a kind of structural representation of the present utility model.(1) body, (2) worm screw, (3) worm gear, (4) high speed shaft pinion wheel, (5) worm-wheel shaft, (6) stepper motor, (7) minute hand shaft gear wheel, (8) minute hand shaft pinion wheel, (9) minute hand shaft, (10) slow-speed shaft gear wheel, (11) slow-speed shaft, (12) slow-speed shaft pinion wheel, (13) hour hand axle gear wheel, (14) hour hands axle sleeve.
Fig. 2 is Figure 1A-A rotation profile;
Fig. 3 is a kind of transmission principle figure of the utility model;
Fig. 4 is prior art transmission principle figure.
With reference to Fig. 1, Fig. 3, this gear train has a convenient combined type body (1) that each parts in it are installed, and stepper motor (6) directly and worm screw (2) rigid attachment is installed in the bottom of body (1), drive worm gear (3) gearing-down on it, this worm gear pair chopped-off head slows down, under high-speed case, by the screw inclined plane transmission of worm gear pair, improved stable working greatly, it is than the present direct transmission of secondary straight-tooth gear, and the worm gear pair three-step gear shift has reduced impact noise then.After the chopped-off head worm gear pair was slowed down, pinion wheel (4) on worm-wheel shaft (5) and minute hand shaft gear wheel (7) engagement were realized minute hand shaft (9) rotating speed requirement again.The rotating speed of hour hands axle sleeve (14) is realized the differential motion of it and minute hand shaft (9) 1:12 after minute hand shaft pinion wheel (8) and slow-speed shaft gear wheel (10) and slow-speed shaft (11) are gone up pinion wheel (12) and hour hand axle gear wheel (13) two-stage speed change.Because the worm gear pair structure is become chopped-off head of the present utility model by the final stage deceleration that has the movement minute hand shaft now slows down, add that former three utmost points deceleration changes two utmost points into, and remove all cock wheels, simplify the structure greatly, make volume, weight and cost all reduce nearly 50%, the stable working raising, noise is reduced to below 30 decibels by original about 120 decibels.
Claims (1)
1, a kind of quartzy great bell movement gear train for building, mainly form by combination body (1), stepper motor (6), worm gear pair (2), (3), minute hand shaft (9), hour hands axle sleeve (14), the multistage straight-tooth gear that is meshed and auxiliary thereof, it is characterized in that direct and worm screw (2) rigid attachment of stepper motor (6), be installed in the bottom of body (1), drive worm gear (3) the speed change transmission that is meshed on it, through straight-tooth gear (4), (7), finish the minute hand shaft rotating speed, hour hands axle sleeve (14) is realized 12: 1 differential motion again through the straight-tooth speed change.
