Description
Technical field
The present invention relates to a kind of physics teaching experimental device, a kind of be used for demonstrating sprocket wheel, chain drive
Experimental provision.
Background technology
Sprocket wheel, chain drive relate to the subject classification such as chain drive, lever mechanics, comprehensive relatively strong, directly by theory
Mapping explanation sprocket wheel, chain drive seem the most jerky, therefore, invent a kind of device gesture for showing sprocket wheel chain drive and exist
Must go.
Summary of the invention
For relations such as moment during visual in image reaction sprocket wheel, chain drive, speed, the invention provides a kind of sprocket wheel
Drive experiments device.
The present invention is achieved in that on base and is respectively provided with set screw from left to right, pole, spring scale, support and
Pole, the pole of the right and left is respectively mounted quiet sprocket wheel, movable sprocket, is connected by chain between quiet sprocket wheel and movable sprocket, quiet chain
Wheel periphery connects wheel rim, and under chain, middle part is provided with expansion tightening wheel, and expansion tightening wheel is rack-mount by adjusting rod, set screw
Being connected with slide plate, slide plate is placed with friction pad, friction pad is connected with spring scale by bracing wire.
The described sprocket wheel that quiet sprocket wheel is multiple different radii combination.
Bottom described friction pad smooth, lubricant can be added if desired and reduce the friction between friction pad and slide plate.
The invention has the beneficial effects as follows: the velocity variations during connection transmission of different radii sprocket wheel can be reflected intuitively,
Also the relation between input power and power output and sprocket radius and wheel rim radius can be reflected by the reading of spring scale, by tool
The experimentation of body and data calculate and can increase the interest of Students ' Learning and can deepen the understanding of student.

Detailed description of the invention
As it can be seen, be respectively provided with set screw 2 on base 1 from left to right, pole 8, spring scale 5, support 6 and pole 8,
It is respectively mounted quiet sprocket wheel 13, movable sprocket 9 on the pole 8 of the right and left, is connected by chain 10 between quiet sprocket wheel 13 and movable sprocket 9,
Quiet sprocket wheel 13 peripheral connection has wheel rim 12,10 times middle parts of chain to be provided with expansion tightening wheel 11, and expansion tightening wheel 11 is arranged on by adjusting rod 7
On support 6, set screw 2 is connected with slide plate 3, and slide plate 3 is placed with friction pad 14, and friction pad 14 is by bracing wire 4 and spring scale 5
Connect.
Embodiment 1:
When carrying out rotating speed and moment experiment, the ratio of the radius and movable sprocket 9 that connect quiet sprocket wheel 13 according to chain 10 obtains quiet chain
The rotating speed of wheel 13, this rotating speed i.e. the rotating speed of wheel rim 12, change different quiet sprocket wheels 13 when testing, for ensureing device
Steadily operating, needs to regulate adjusting rod 7 position on the frame 6, so that expansion tightening wheel 11 rises or moves down so that chain 10 is in
Tensioner state.
Embodiment 2:
When measuring chain, chain gear transmission, placing friction pad 14 on slide plate 3, the one side that friction pad 14 is smooth contacts with slide plate 3,
Slide plate 3 connecting stay wire 4, reconnects spring scale 5, and regulation set screw 2 makes slide plate 3 rise, and friction pad 14 closely connects with wheel rim 12
Touching, give the certain dynamics of movable sprocket 9 and rotating speed, chain 10 band sound sprocket wheel 13 rotates, and wheel rim 12 first has to overcome when rotating
The friction of friction pad 14, record wheel rim 12 uniform rotation time spring scale numerical value, finally, by give movable sprocket 9 dynamics and
Rotating speed carries out comparing calculation with the rotating speed of the wheel rim 12 calculated and the numerical value of spring scale 5, complete input power and power output with
The explanation demonstration of the relation between sprocket radius and wheel rim radius.
