Abstract
The utility model relates to a movement synthetic demonstration instrument, which comprises two motors, two pairs of driving and driven gears, two pairs of bearing seats and bearings, two screw rods, a base plate, a pad seat and a movable block. One end of one screw rod is sheathed with the driven gear, and the bulge of the driven gear is a shaft sleeve which is fixedly sheathed with the bearing, wherein the bearing is fixed on the bearing seat which is fixed on the base plate through fixing screw bolts. The driven gears are driven be the driving gears which are driven by the motors. The other end of the screw rod is horizontally extended in the internal thread hole of the movable bearing seat. The dynamic force end of the other screw rod is the same as that of the first screw rod. The second screw rod needs to pass through the movable bearing seat, and the other end thereof is provided with the movable block. The motion composition demonstration instrument has simple operation, and good demonstration effects can be obtained.
Description
Technical field
The present invention relates to a kind of instruments used for education, particularly relate in the physics of demonstration middle school about the synthetic demonstration instrument that moves.
Background technology
In middle school teaching material about the synthetic experimental technique that moves: fills with water in being about the glass tube of 80cm～100cm one end sealing, put the small cylinder that a red wax is made in the water, with the openend of glass tube plug jam-pack.This glass is close to blackboard vertically is inverted, red wax stone just at the uniform velocity rises along glass tube, does rectilinear motion, and red wax stone is above top straight line rises to.Then, glass vertically is inverted, at the uniform velocity mobile to the right or speed change moves with the hand level with glass tube when red wax stone rises, observes the motion of red wax stone, it will be appreciated that it is moving linearly or curvilinear motion obliquely.
The speed of this demenstration method manual control horizontal direction, velocity magnitude and variation thereof are difficult to grasp, and the track of resultant motion can't be described, can't carry out instruction analysis, the student is difficult to see the track of motion, moreover the experimental implementation inconvenience, be difficult for succeeding, and can't obtain better teaching.
Summary of the invention
For solve motion composition demonstrating instrument on the teaching material be difficult for succeed and the unconspicuous problem of teaching efficiency, the present invention proposes a kind of motion composition demonstrating instrument, this demonstrator is mainly by two motors, two pairs of main driven gears, the two pairs of bearing seats and bearing, two screw rods, substrate, base, formations such as movable block, it is characterized in that: be with follower gear on the end of a screw rod, the projection of this follower gear is an axle sleeve, be with bearing on this axle sleeve regularly, this bearing fixing is on bearing seat, this bearing seat is fixed on the substrate by set bolt, follower gear drives by driving gear, driving gear is by driven by motor, and the other end level of screw rod stretches in the hole that has internal thread of movable axle bearing.One end of another screw rod also is with a follower gear, axle sleeve on this follower gear is with bearing regularly, this bearing fixing is in a movable axle bearing, this screw rod level is passed the movable axle bearing, the other end at this screw rod passes a movable block, this movable block is connected with this screw rod by internal thread, and follower gear drives by driving gear, and driving gear passes through driven by motor.
This motion composition demonstrating instrument is simple to operate, can obtain teaching demonstration effect preferably.

Embodiment
As shown in Figure 1, be with follower gear 4 on one end of screw rod 3, the projection of follower gear 4 is an axle sleeve 30, be with bearing 5 on the axle sleeve 30 regularly, bearing 5 is fixed on the bearing seat 6, and bearing seat 6 is fixed on the substrate 10 by set bolt 7, and follower gear 4 drives by driving gear 2, driving gear 2 drives by motor 1, and the other end level of screw rod 3 stretches in the hole that has internal thread of movable axle bearing 14.One end of screw rod 13 is with follower gear 15, axle sleeve on the follower gear 15 is with bearing 16 regularly, bearing 16 is fixed in the movable axle bearing 14, screw rod 13 levels are passed movable axle bearing 14, the other end at screw rod 13 passes a movable block 8, movable block 8 is connected with screw rod 13 by internal thread, and follower gear 15 drives by driving gear 12, and driving gear drives by motor 11.
Connect the power supply of motor 1, screw rod 3 rotates in movable axle bearing 14, forces movable axle bearing 14 to drive screw rod 13 and adjunct and movable block 8 thereof and moves along screw rod 3 together.Movable block 8 is as the synthetic object of reference of motion.Be connected in series swept resistance in the loop as Fig. 2 motor 1, show the rotating speed of motor 1 adjustable be that movable block 8 is variable along the speed of screw rod 3 directions.When motor 11 energized, movable block 8 will be at the uniform velocity mobile along screw rod 13 directions.If simultaneously with motor 1 and motor 11 energized, the motion of movable block 8 will show the synthetic phenomenon of motion so.
