The utility model can unidirectionally rotated by the driven working shaft and can have more than two working speed change effects.
Description
Technical field
The utility model relates to mechanical transmission, specifically a kind of perseverance to the mechanical transmission speed change gear.
Background technique
At present, if almost machinery all be unable to do without transmission and speed change gear, therefore kind, the style of mechanical transmission and speed change gear are various, piece do not win number, the working shaft of existing mechanical transmission and speed change gear and its transmission is down that suitable, reverse rotational direction can be arranged in working order, that is to say that when power source has changed sense of rotation working shaft is also correspondingly attacked and become sense of rotation.This is the state that generally operates in general mechanical industry, and along with the development of mechanical industry and relevant industries, the design that has need working shaft can only be permanent to rotation, also promptly forever can only be towards a direction rotation, therefore existing transmission, speed change gear are difficult to satisfy the demand, the speed change of existing in addition transmission, speed change gear is constant, is difficult to have multiple speed changing effect.
Summary of the invention
The purpose of this utility model provides a kind of mechanical transmission, speed change gear, and it can make by the working shaft perseverance of transmission to rotation, if the sense of rotation and the rotating speed of change power source can make working shaft that the effect of multiple speed change is arranged.
Technical solution of the present utility model is the line shaft at existing transmission, speed change gear, on the basis of working shaft, the utility model is two overrunning clutchs of serial connection on line shaft or working shaft particularly, two overrunning clutchs are for the reverse each other work structuring of the transmission of power source rotating force, and each overrunning clutch all links to each other with working shaft or power wheel shaft by one group of gear train, belt or chain separately.
The above overrunning clutch can overcoat gear, belt pulley or sprocket wheel, or self outer shroud tooth, belt pulley or sprocket wheel.
The utility model is that the gear Gear combination that be fixed in working shaft or power wheel shaft on intermeshing with it that is set in the overrunning clutch periphery is gear train, or is with the gear train of being made up of jointly both meshed gears of energy and its between the gear fixing on the overrunning clutch of tooth and working shaft or the power wheel shaft outside it.
Alleged belt of above the utility model or sprocket wheel link to each other and are meant that belt sleeve is on the peripheral belt pulley of clutch or sprocket wheel and working shaft or on motive power wheel shaft upper pulley or the sprocket wheel.
Overrunning clutch that the utility model is said so is now commercially available prior art products, also claim unilateral bearing, be only can the single direction transmission the mechanical transmission basic part, when power source during towards the rotation of direction, overrunning clutch dallies automatically, when power source rotated to another way, overrunning clutch engaged automatically.
The utility model has the advantages that it can make by the working shaft folk prescription of transmission to rotation, and can make working shaft that two or more speed changing effect is arranged.
Description of drawings
Fig. 1 is an organigram of the present utility model;
Fig. 2 is that the utility model adopts existing free wheeling sprag clutch organigram.
Embodiment
According to shown in Figure 1, the utility model is dynamic takes turns 2 and the power wheel shaft, being serially connected with model on the power wheel shaft is that CK-A2052 overrunning clutch 1 and model are CK-A2052 overrunning clutch 3, overrunning clutch 1 and overrunning clutch 3 are for the reverse each other work structuring of the rotating force transmission of power source, overrunning clutch 1 can be fixed in the first Gear center of gear train 4, first gear is meshed mutually with gear on being fixed in working shaft 6 and forms gear train 4, the overrunning clutch 3 outer teeth that are with, and form gear train 5 jointly by both meshed gears of energy and its between the gear of fixing on the working shaft 6, need to prove that here this intermediate gear is to be fixed on the rotatable axle 7.
With reference to the accompanying drawings, the utility model is that the power of rotation transmits by overrunning clutch 1 and affiliated respectively moving gear group 4 and the gear train 5 of overrunning clutch 3, the position of overrunning clutch can be designed and any axle of each tooth belt on the same group or chain respective action makes up, and overrunning clutch 1 and overrunning clutch 3 are for the reverse each other work structuring of the transmission of power source rotating force.Overrunning clutch 1 is in separated state (idling conditions) when motive power wheel 2 turns clockwise transmission, overrunning clutch 3 then in running order (being jointing state), this moment, gear train 5 was started working, because of gear train 5 numbers of gears are odd number, so do not change sense of rotation when being delivered to working shaft 6, also promptly this moment, working shaft turned clockwise.Or overrunning clutch 1 in running order (jointing state) overrunning clutch 3 then is in separated state (idling conditions) when motive power wheel 2 turns clockwise transmission.During overrunning clutch 1 work, this moment, gear train 4 was started working, because of gear train 4 numbers of gears are even numbers, so changed the direction of rotation when being delivered to working shaft 6, this moment, working shaft 6 also turned clockwise, when the power of rotation when to clockwise rotate with the speed that rotates counterclockwise be the same, the rotating speed that is delivered to working shaft is because power source transmits by gear train 4 and gear train 5, and the speed ratio of gear train 4 and gear train 5 is different, when so the power of rotation is delivered on the working shaft 6 when clockwise rotating or rotating counterclockwise with same rotating speed, the sense of rotation of working shaft 6 is unidirectional, but rotating speed can be two kinds of different rotating speeds, if the power rotating speed of rotation has X kind rotating speed, and the sense of rotation of energy conversion rotating power, working shaft 6 can be obtained X and multiply by 2 kinds of speed changing effect so.
Overrunning clutch of the present utility model is except can being in transmission connection with gear train and working shaft, can also adopt being in transmission connection of belt type or chain type, also can use gear, belt, the chain combined type connects, precondition is that two groups of adhering to separately of overrunning clutch 1 and overrunning clutch 3 are in transmission connection, one group effect is to guarantee that the sense of rotation in transferring power source is unidirectional to the sense of rotation of working shaft 6, the sense of rotation that another group effect by the gear transmission break-in guarantees the transferring power source is different direction to the sense of rotation of working shaft 6, in a word so long as on power wheel shaft or working shaft, implement two overrunning clutchs of serial connection, and two overrunning clutchs are for the reverse each other work structuring of the transmission of power source rotating force, and finally reach the working shaft folk prescription and all belong to scope of the present utility model to the technological scheme of rotating.
According to shown in Figure 2, the overrunning clutch 1 and 3 that the utility model adopts, be free wheeling sprag clutch, free wheeling sprag clutch by: outer shroud 8, interior ring 9, voussoir 10 etc. are formed, working principle is an interior ring 9 fixedly the time, and outer shroud 8 clockwise directions rotate, and voussoir 10 is locking not, outer shroud 8 can rotate (being idling conditions) automatically, voussoir 10 lockings (jointing state) when outer shroud 8 counterclockwise rotates.
