Description
Technical field
The present invention relates to mechanical transmissioning technology, particularly a kind of transmission device of two-way Driving Torque.
Background technique
All the time, the output shaft of the power source of motor etc. is connected to the wheel disc such as sprocket wheel or pulley, with this wheel disc for starting point, by chain, the wirerope driving torque of the transfer motion powers such as belt.
Existing technical paper comprises the patent documentation of Japan, a kind of transmission device is disclosed in special publication number 2011-535319 publication, such as, patent documentation 1 is recorded: carrying case comprises, as can the sprocket wheel 1 of free pivotal output block or output block, can the wheel shaft 4 of free pivotal output block and input block, between sprocket wheel 1 and wheel shaft 4, start engages and can free pivotal multiple planetary pinion 8, and the movable cam part 202 optionally engaged with this planetary pinion 8.And when cam member 202 engages with planetary pinion 8, planetary gear portion can stop revolution.That is, when cam part 202 does not engage with planetary pinion 8, the gyratory directions of sprocket wheel 1 is contrary with the gyratory directions of wheel shaft 4.
That is, the transmission device (carrying case 100) in patent documentation makes the revolution of input and output parts reverse by switching selectivity, can to predetermined direction driving torque.
Traditional transmission device Problems existing: traditional transmission device exports to predetermined load in order to the torque that will export from power source, switching towards needs according to torque, thus can to this load transmission.But, if that as the driving belt of two sliding doors opened or two-way carrying, when needing load device to provide two-way torque, the bi-directional drive of transmission simultaneously power at least need two groups of power sources (or transmission device) simultaneously.Therefore, whole driving structure becomes complicated, and cost increases and then becomes a problem.
Summary of the invention
Object of the present invention is exactly for overcoming the deficiencies in the prior art, propose for above-mentioned problem, its object is to provide a kind of transmission device, the unidirectional torque exported from power source be can be used as any transmission of torque of two-way (being according to circumstances unidirectional or just reverse) by it, still further provides a kind of transmission device and the load device with this transmission device.
The present invention is realized by such technological scheme: a kind of transmission device of two-way Driving Torque, it is characterized in that, comprise wheel disc, central axis C and reversing device, central axis C comprises at least two wheel discs side by side, wherein, 1st wheel disc is fixedly arranged on central axis C, and with central axis C for axle, with central axis C synchronous axial system; 2nd wheel disc and the 1st wheel disc radial parallel, be arranged side by side, rotate centered by the axis of central axis C; Be connecting body between 1st wheel disc and the 2nd wheel disc, its center hole is directly or indirectly fixed on central axis C, reversing device is made up of gear train, the gear train of reversing device comprises at least three gears, be separately positioned on the 1st wheel disc, the 2nd wheel disc and connecting body, gear on 1st wheel disc and the 2nd wheel disc by the intermediate gear transmission on connecting body, mutual transmitting torque, the transmission of torque of output is given to the other side by the 1st wheel disc or the 2nd wheel disc; When the transmission of torque utilizing reversing device the 1st wheel disc or the 2nd wheel disc to be exported is to the other side, the 1st wheel disc and the 2nd wheel disc rotate backward mutually;
When central axis C is motor output shaft, the 1st wheel disc and the 2nd wheel disc drive a load respectively, when central axis C is a load input shaft, the 1st wheel disc or the 2nd wheel disc then drive by the driving wheel on the motor output shaft of external power supply.
The effect of invention
1, the unidirectional torque by exporting from power source, the while of making any one in the 1st wheel disc or the 2nd wheel disc pivotal, makes the 1st wheel disc and the 2nd wheel disc mutually reverse by reversing device, the wheel disc of the opposing party can also be made to turn round at other direction.That is, transmission device of the present invention, by mutual reverse pivotal 1st wheel disc and the 2nd wheel disc, using the unidirectional torque that provides from power source etc. as two-way torque transmission simultaneously.Therefore, according to the present invention, by while driving mechanism overall simplification, economic benefit can also be realized.By the interlock of the 1st umbrella gear, the 2nd umbrella gear and middle umbrella gear, use easy structure just can make the 1st wheel disc or the reversion of the 2nd wheel disc.That is, transmission device can be formed with less parts, achieve the simplification of device and decrease cost.
