Description
Technical field
The utility model relates to mechanical transmission fields, particularly relates to a kind of clutch device that can commutate fast.
Background technique
Clutch, as a kind of vitals of machine driven system, is responsible for the work of power cut or connection.Clutch device is of a great variety, mainly contain friction clutcch, fluid coupling, magnetic clutch etc. several, but existing clutch all can only realize input shaft and output shaft rotating Vortex function by its working principle.In addition, for some machinery equipment, its power system needs commutation function in transmission.Such as lathe adopts breast wheel to adjust screw mandrel rotation direction, and to realize cutter break-in function, conventional tri-star wheel changement as shown in Figure 1.Joystick diverse location, can realize the switching that follower turns to.In order to avoid beating tooth, the mechanism such as often to need stop operating during switching, in the middle of this is invisible, reducing the utilization efficiency of machine.
At present, the clutch device simultaneously with " clutch " power train and output shaft " fast commutation " function does not temporarily occur.In prior art, Chinese utility model patent CN203335742 discloses a kind of double single-pinion planetary gear automatic clutch and realizes normal clutch function.But owing to adopting two-row planetary gear structure, needed for it, number of components is more, causes manufacture cost relatively high, potential faults increases, cost is more expensive.In addition, this clutch cannot realize the quick commutation function of output shaft, and its function and efficacy is confined to normal clutch.
Visible, existing clutch also exists following deficiency:
1, normal clutch can not realize commutation function, cause must setting up a set of changement in some machine driven systems, thus make system more complicated, and the matched design of connecting element, processing and assembling add workload, and the cost of transmission system is improved further.
2, conventional at present tri-star wheel changement structure commutation process needs first to be separated between engaging gear to engage again, and this causes the commutation when mechanism runs there is impact phenomenon, completes commutation after can only waiting mechanism's reduction of speed.This not only lowers utilization efficiency, also reduce working life to a certain extent.Tri-star wheel changement structure is equivalent to fixed shaft gear train design in each working state, and for planetary gear type epicyclic gear train, its physical dimension is comparatively large, and transmission dynamic performance is poor, is lessly applied to heavy load transmission field.
3, existing double single-pinion planetary gear clutch, its number of components is more causes assembling difficulty, potential faults is large, cost is expensive, and does not take corresponding measure to make clutch adjustable in conjunction with speed, cannot realize the sliding wear function of existing vehicle-mounted clutch.In addition, this clutch cannot realize the commutation function of output shaft, defines its using scope, and its function and efficacy is only limitted to normal clutch.Meanwhile, when this clutch is in conjunction with work, utilize the deceleration principle of first row planetary gear train and the speedup principle of second row planetary gear train to carry out speed change and superpose the working state reaching velocity ratio 1:1, compared with the bonding state of normal clutch, its transmission efficiency is lower.
