Description
Technical field
The utility model relates to electric power conveying technology field, especially a kind of electric commutator.
Background technology
The simplest electric commutator is no more than terminal block and connector assembly, but these simple electric commutators can only be applicable to the connection of the electricity between fixing electrical component.For the switching between two parts having a relative motion, the electric commutator of terminal block and connector assembly and so on can complete by no means.So just in succession there is comparatively complexity that spiral adapter, slip ring and contact form, adapter well known.This kind of adapter can realize the connection of the electricity between two relative movement parts, therefore, obtains extensively weary application.Such as, but these electric commutators also expose some self weakness in the use of some occasions: the spiral adapter relative rotation be only applicable between rotatable parts and fixed part is less than the occasion of 360o degree; The adapter that slip ring and contact form, owing to there is contact resistance and easily causing frictional sparking, is not often suitable for the small and weak signal of telecommunication of transmission and does not allow to be used in the occasion occurring electric noise due to sparking, not more being suitable for marine environmental conditions.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of electric commutator, can realize the transmission of the signal of telecommunication that relative rotation is larger between stationary parts and moving component.
In order to solve the problems of the technologies described above, the utility model comprises the cylinder for storing cable, the gyroaxis of described cylinder is fixedly installed the first storage drum, described first storage drum is provided with the sleeve with gyroaxis matched in clearance near cylinder side, the two ends of described sleeve are fixedly installed ratchet respectively, the second storage drum is also provided with between described ratchet and cylinder, described second storage drum and gyroaxis matched in clearance be fixed on bracing frame, described first storage drum and the second storage drum are provided with near the end face of ratchet the ratchet mated with ratchet, described sleeve is provided with wheel bracket, the top of described wheel bracket is provided with the guide wheel that can be rotated about axis, the axis of described guide wheel is vertical with gyroaxis.
Friction plate is provided with between described wheel bracket and sleeve.
Described wheel bracket is positioned at gyroaxis opposite side and is also provided with balancing weight.
The utility model achieves the electricity rotating cable and attached cable relative rotation larger and transfers, and is contactless, continuous print energising.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view in figure A-A direction.
Embodiment
Embodiment cited by the utility model; just understand the utility model for helping; should not be construed as the restriction to the utility model protection range; for those skilled in the art; under the prerequisite not departing from the utility model thought; can also improve the utility model and modify, these improve and modification also falls in the scope of the utility model claim protection.
As depicted in figs. 1 and 2, the utility model comprises the cylinder 1 for storing cable, the gyroaxis 2 of described cylinder 1 is fixing on the base 11 by bearing 21, described gyroaxis 2 is provided with the first storage drum 3, described first storage drum 3 is provided with the sleeve 4 with gyroaxis 2 matched in clearance near the side of cylinder 1, the two ends of described sleeve 4 are fixedly installed the first ratchet 51 and the second ratchet 52 respectively, the second storage drum 6 is also provided with between described second ratchet 52 and cylinder 1, described second storage drum 6 is with gyroaxis 2 matched in clearance and be fixed on bracing frame 7, this bracing frame 7 can be the shell of electric commutator.
Described first storage drum 3 and the second storage drum 6 are respectively arranged with near the end face of ratchet the first ratchet 81 and the second ratchet 82 mated with ratchet, when the first storage drum 3 rotates with gyroaxis 2, the first ratchet 81 on described first storage drum 3 promotes the equidirectional rotation of the first ratchet 51, when the first storage drum 3 rotates with gyroaxis 2 reverse direction, the second ratchet 82 on described second storage drum 6 props up the second ratchet 52.
Described sleeve 4 is provided with wheel bracket 9, friction plate 10 is provided with between described wheel bracket 9 and sleeve 4, during such pawl wheel, drive the equidirectional rotation of wheel bracket by frictional force, the size of described frictional force can be regulated by the spring screw 92 be arranged on introduction support 9.The top of described wheel bracket is provided with the guide wheel 91 that can be rotated about axis, and the axis of described guide wheel 91 is vertical with gyroaxis 2.
In order to realize the balance of wheel bracket 9 in rotation process, described wheel bracket 9 is positioned at gyroaxis 2 opposite side and is also provided with balancing weight 93.
For the ease of understanding the utility model further, below operation principle of the present utility model and process are described further.
Viewed from the A-A direction Fig. 1, when cylinder 1 rotates clockwise, the gyroaxis 2 of cylinder 1 drives the first storage drum 3 also to rotate clockwise, and rotational angular velocity is identical, is set to ω.Now, under the effect of cable 12 tensile force, wheel bracket 9 rotates with the first storage drum 3, this be cable 12 on the second storage drum 6 by guide wheel 91 around entering the first storage drum 3.
When cylinder 1 rotates with ω speed counterclockwise, the gyroaxis 2 of cylinder 1 drives the first storage drum 3 also to rotate with ω speed counterclockwise, and the first ratchet 81 be now fixed on the first storage drum 3 promotes the first ratchet 51 and also makes counterclockwise movement.Owing to there is larger frictional force between the sleeve 4 between two ratchets and wheel bracket 9, therefore wheel bracket 9 is also driven to rotate counterclockwise.At this moment the first cable 12 of easing out of storage drum 3 by guide wheel 91 around entering the second storage drum 6.
