Abstract
The utility model relates to a driving device for changing reciprocating straight motion into rotary motion. The utility model comprises a support frame, a driving shaft, a chain wheel, chains and a spring adjustment device. The chain wheel can only drive the driving shaft to rotate along one direction. The support frame is provided with two sliding rods which move to and fro in a straight mode. The support frame is spaced and supported by a guide wheel which can rotate around the support frame. The two sliding rods are respectively connected with a chain. The two chains respectively bypass the chain wheel matched with the two chains in a driving mode to be connected with a steel cable which is spaced by a fixed pulley flatly arranged, and the steel cable is around the fixed pulley. The fixed pulley is connected with the spring adjustment device. Mechanical efficiency is greatly improved, and the utility model can be used in various moving devices.
Description
The utility model relates to a kind of transmission device that rotatablely moves that linear reciprocating motion is become.
Linear reciprocating motion being changed into rotatablely move now needs piston to drive crank by connecting rod, drives crankshaft rotating by crank again, realizes the work done of transmission power.For example the kind of drive of steam engine is exactly like this.The connecting rod of this structure and crank active force produce the component of several different directions owing to angle is different, friction between slide block and slideway, connecting rod and crank swing up and down loss and the drawback that the rotation of the power of generation and flywheel causes the multiple reasons such as dead point of piston motion to produce, and all greatly reduce mechanical efficiency.
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of connecting rod and crank of saving is provided, and the reciprocal of power source of doing linear reciprocating motion firmly is converted to rotating power and the transmission device of work done.
The purpose of this utility model realizes by following technical proposals:
Linear reciprocating motion is become the transmission device that rotatablely moves have support, transmission shaft, sprocket wheel, chain, spring regulating device, sprocket wheel can only drive transmission shaft and rotate along a direction, its technological scheme is that described support is provided with two slide bars doing linear reciprocating motion, two slide bars are by the spacing supporting of upper saw pulley that can rotate around support, two slide bar front ends connect a chain respectively, these two chains all are connected with wire rope after walking around the sprocket wheel that transmission with it cooperates respectively, wire rope is spacing by its horizontally disposed static pulley of walking around, and static pulley is connected with spring regulating device.
In the technique scheme, be the roller of being located on the support that is positioned at slide bar upper end and lower end thereof with the upper saw pulley of the spacing supporting of slide bar.Be horizontally disposed with static pulley on the support, the wire rope two ends of walking around this static pulley are connected with two slide bars respectively.Below chain, have on the support and can change the supporting rollern that slide bar is done the angle of linear reciprocating motion.
The utility model is because its said structure, make it with original by piston, connecting rod, the conventional transmission power mode of crank and bent axle becomes no connecting rod and crank, the transmission power mode of bent axle, the reciprocating power of the power source (two slide bars) of linear reciprocating motion will be done, directly become stable rotation power, eliminated original transmission device owing to the shortcoming of connecting rod with the different component of the different generations of active force angle of crank, also eliminated because the friction between slide block and slideway, swinging up and down and disadvantage that a large amount of effect losses such as piston motion dead point bring of connecting rod and crank makes that mechanical efficiency is effectively big to be improved.It has reduced space, makes very easyly, can be used for the manpower transmission of toy car, bicycle and other class equipment that can be manned.
The utility model is described in further detail below in conjunction with embodiment:
Fig. 1 is a plan view of the present utility model.
Fig. 2 is a plan view of the present utility model.
As shown in Figure 1 and Figure 2, the utlity model has support 2, transmission shaft 9, sprocket wheel 10 and 10 ', chain 8 and 8 ', spring regulating device 13, two slide bars 6 and 6 ', upper saw pulley, wire rope 11 and 14, static pulley 12 and 1, supporting rollern 7.Sprocket wheel 10 and 10 ' can only drive transmission shaft 9 and rotate along same direction, and this structure is a prior art.Described support 2 is provided with 6,6 ', two slide bars of two slide bars 6 of doing linear reciprocating motion, 6 ' by the spacing supporting of upper saw pulley that can rotate around support 2, and upper saw pulley is the roller of being located on the support 4,5,3 that is positioned at slide bar 6,6 ' upper end and lower end thereof.Two slide bars 6,6 ' front ends connect a chain 8,8 ' respectively, sprocket wheel 10,10 ' back that these two chains 8,8 ' are walked around the cooperation of transmission with it respectively all are connected with wire rope 11, wire rope 11 is spacing by its horizontally disposed static pulley 12 of walking around, and static pulley 12 is connected with spring regulating device 13.When the utility model uses, spring regulating device 13 should be fixed on a certain position.For making two slide bars whole device when the to-and-fro motion compact, can make to be horizontally disposed with static pulley 1 on the support 2, wire rope 14 two ends of walking around this static pulley 1 are connected with two slide bars 6,6 ' respectively.Tighten the nut on the spring regulating device like this, device is tightened.Below chain 8,8 ', have on the support 2 and can change the supporting rollern 7 that slide bar 6,6 ' is done the angle of linear reciprocating motion.Be the center with supporting rollern 7 like this, sliding rod rack 2 rotates an angle beta, can make slide bar 6,6 ' become the β angle to do linear reciprocating motion with horizontal plane, and the β value can change in 0-90 °.During the utility model work, slide bar 6 moves right, drive chain 8 motions, sprocket wheel 10, transmission shaft 9 are turned clockwise, outputting power, after steel wire fly 11, static pulley 12, sprocket wheel 10 ', chain 8 ' transmission, slide bar 6 ' is to left movement simultaneously, sprocket wheel 10 ' rotation counterclockwise this moment is to transmission shaft 9 not works done.In like manner, when slide bar 6 ' moved right, it was to the transmission shaft work done and outputting power, and this moment, slide bar 6 was to left movement.So circulation is exported successively and stable rotation power transmission shaft 9.
