Abstract
The utility model relates to a movement driving mechanism, comprising a motor, a driving belt, a first driving gear, an endless screw, worm wheels, racks, etc. The movement driving mechanism is characterized in that the movement driving mechanism is also equipped with a second driving gear; the motor is connected with the second driving gear which is equipped with belt pulleys through the driving belt; the second driving gear is meshed with a gear which is coaxially connected with the endless screw; the endless screw is meshed with the worm wheel; the worm wheel is meshed with the rack which is installed on a driving disc; the position on one side wall relative to the second driving gear is equipped with a slotting, and the grinding teeth of the driving gears are exposed through the slotting. When normally transmitting, the motor is turned to drive the driving gear which drives the endless screw, and the endless screw drives the worm wheel which drives the rack to move. When once debugging is conducted because of failure or no power, the driving gear is just needed to switch by hand, and driving members can be driven to move.
Description
Technical field:
The utility model relates to light medium movement product, particularly relates to a kind of employing drive of motor worm and gear and drives movement.
Background technology:
As shown in Figure 1, I provide a kind of movement in the utility application of number of patent application 03223780.4, this kind movement adopts motor 1 to drive worm screw 3 by belt 2 and rotates, and then worm gear 4 is given in transmission, give tooth bar by worm gear 4 transmissions again, thus drive dish turnover movement.Adopt the movement of this kind method transmission, it is simple to have a drive mechanism, the advantage of reliable transmission.Because motor is directly by the belt pulley of belt gear on worm screw, worm screw transmission worm gear drives again tooth bar moves.These moving links are installed in the movement, and at the volley, in case when motor or driving member break down, or carry out non-transformer when debugging, under the situation of not opening the movement lid, transmission component is moved, installed video disc also just can't take out.
Summary of the invention:
The purpose of this utility model is to provide a kind of movement gear train, make when motor or driving member break down, or do not have when debugging electricity, under the situation of not opening the movement lid, can make video disc that transmission component moves, that can take out and pack into.
The movement gear train of realizing the utility model purpose comprises motor, formations such as driving belt, first transmission gear, worm screw, worm gear, tooth bar, it is characterized in that being provided with second transmission gear, motor connects with second transmission gear that is provided with belt pulley by driving belt, second transmission gear is meshed with coaxial first gear that is located at worm screw, the worm and wheel engagement, worm gear and tooth bar engagement, tooth bar is installed on the drive plate; Position at relative second transmission gear of sidewall is provided with a fluting, and the grinding tooth of second transmission gear sees through fluting and exposes out.When normal transmission, drive second transmission gear by the rotation of motor, again by the second transmission gear snail drive worm screw, worm screw drives worm gear, the motion of worm gear drives tooth bar.In case break down or non-transformer when debugging, only with hand is stirred second transmission gear, can drive transmission component and move.
As improvement of the present utility model, the grinding tooth of described second transmission gear sees through the sidewall that fluting exceeds movement.
Adopt movement gear train of the present utility model, when motor or driving member break down, or there be not when debugging electricity, under the situation of not opening the movement lid, transmission component is moved, the video disc that can take out and pack into, simultaneously, have easy to operate, advantage of simple structure.
Description of drawings:
Cassette mechanism structure synoptic diagram before the improvement of Fig. 1.
Fig. 2 is the utility model cassette mechanism structure assembling synoptic diagram.
Specific embodiment:
As shown in Figure 2, a kind of movement gear train, comprise motor 5, formations such as driving belt, first transmission gear 7, worm screw 8, worm gear 9, tooth bar (not shown) is characterized in that being provided with second transmission gear 10, and motor 5 connects with second transmission gear 10 that is provided with belt pulley by driving belt, second transmission gear 10 is meshed with coaxial first transmission gear 7 that is located at worm screw 8, worm screw 8 and worm gear 9 engagements, worm gear 9 and tooth bar engagement, tooth bar is installed on the drive plate; The grinding tooth that is provided with a fluting 6, the second transmission gears 10 in the position of relative second transmission gear 10 of sidewall sees through fluting 6 and exposes out, and the grinding tooth of second transmission gear 10 sees through the sidewall that fluting 6 exceeds movement.When normal transmission, drive second transmission gear 10 by the rotation of motor 5, drive by second transmission gear 10 again that first transmission gear 7, first transmission gear 7 drive worm screws 8, worm screw 8 drives worm gears 9, worm gear 9 drives the tooth bars motion.In case break down or non-transformer when debugging, only with hand is stirred second transmission gear 10, can drive transmission component and move.
Claims (2)
1. a movement gear train comprises motor, formations such as driving belt, first transmission gear, worm screw, worm gear, tooth bar, it is characterized in that being provided with transmission gear, motor connects with second transmission gear that is provided with belt pulley by driving belt, second transmission gear is meshed with coaxial first transmission gear that is located at worm screw, the worm and wheel engagement, worm gear and tooth bar engagement, tooth bar is installed on the drive plate; Position at relative second transmission gear of sidewall is provided with a fluting, and the grinding tooth of second transmission gear sees through fluting and exposes out.
2. movement gear train as claimed in claim 1 is characterized in that the grinding tooth of described second transmission gear sees through the sidewall that fluting exceeds movement.
