Such as CN202251514U disclosed " jaw clutch ", comprise supporting frame, bearing support, minor sprocket, axle, left half-clutch, hinge wheel, right semi-clutch, spring is regulated double-screw bolt, the pearl of rolling left keeps double-screw bolt, the ball supported spring, ball, draw ring, the clutch support spring, spring seat, pull bar, sliding sleeve, bracing wire joint, backguy, right ball keeps double-screw bolt, described hinge wheel and half-clutch device link together, and can rotate around axle together, described right semi-clutch is connected with the clutch support spring, right semi-clutch can slide left under the thrust of clutch support spring, then be combined with left half-clutch, right semi-clutch is connected with axle by four balls on the right, and axle is connected with minor sprocket by key; The clutch of this kind structure, although mechanical structure is good, available backguy is carried out the telecontrol clutch to this clutch, its mechanical structure is obviously complicated, and can not transmit larger moment of torsion.
Summary of the invention
For solve engaging and disengaging gear complex structure of the prior art, rate of fault higher, can transmit the larger problems such as moment of torsion, the utility model provides power transmission castellated engaging and disengaging gear.
To achieve these goals, the utility model adopts following technological scheme: the castellated engaging and disengaging gear of power transmission, comprise transmission shaft, and it is characterized in that: be set with left gear, middle gear and the right gear that arrange left, center, right at transmission shaft; In the endoporus both sides of middle gear, left inside tooth and right inside tooth are set respectively, the setting that matches with left gear of left inside tooth, left gear can embed in the left inside tooth, and middle gear drives the left gear rotation; Right gear can embed in the right inside tooth that is equipped with, and middle gear drives the right gear rotation; On left gear and right gear, be respectively arranged with left return spring and right return spring, give respectively left gear and right gear acting force of the spring.
Further feature is: left return spring empty set is on transmission shaft, and two ends are separately positioned between left gear and the left bearing; Right return spring, empty set are on transmission shaft, and two ends are separately positioned between middle gear and the right bearing.
In the left inside tooth and right inside tooth of middle gear, all be provided with shaft block ring.
The speed changing structure of actuating unit of the present utility model with respect to prior art, has following beneficial effect:
1, the utility model is simple in structure, forms castellated clutch structure between three driving gears directly arranging in left, center, right, drives at the same time or separately left and right two gears by the gear of centre and rotates, and mechanical structure is obviously simplified.
2, jaw clutch of the present utility model is simple in structure, by simple mechanical transmission, just can realize smoothly advancing or the left and right needs that travel that turn to etc. of traveling gear, and handling obviously strengthens.
3, its rate of fault is minimized, and has reduced the difficulty of maintenance, and has prolonged working life.
4, can transmit larger moment of torsion, adapt to the powerdriven needs of large-sized power device.

Fig. 1 is the utility model jaw clutch structure sectional view.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the castellated engaging and disengaging gear of power transmission that the utility model is realized comprises transmission shaft 1, is set with three driving gears that arrange left, center, right, i.e. left gear 2, middle gear 3 and right gear 4 at transmission shaft 1; Middle gear 3 and external driving gear engagement are given engaging and disengaging gear of the present utility model with transmission of power during assembling.
Endoporus both sides at middle gear 3, left inside tooth 31 and right inside tooth 32 are set respectively, the setting that matches with the left gear 2 that is arranged on its left side of left inside tooth 31, left gear 2 is (under the clutch shifter effect) when moving axially, can embed in the left inside tooth 31, by the external tooth engagement of left inside tooth 31 with left gear 2, middle gear 3 drives left gear 2 and rotates; In like manner, right gear 4 can embed in the right inside tooth 32 that is equipped with, and by the external tooth engagement of right inside tooth 32 with right gear 4, middle gear 3 drives the right gear 4 that is equipped with and rotates; On left gear 2 and right gear 4, be respectively arranged with left return spring 5 and right return spring 6, give respectively left gear 2 and right gear 4 acting force of the spring, make the bonding state of its maintenance and middle gear 3, under the clutch shifter effect, just separation.Left return spring 5 empty sets are on transmission shaft 1, and two ends are separately positioned between left gear 2 and the left bearing; Right return spring 6, empty set are on transmission shaft 1, and two ends are separately positioned between middle gear 3 and the right bearing, produce respectively acting force of the spring.
In the left inside tooth 31 and right inside tooth 32 of middle gear 3, all be provided with shaft block ring 7, the impact during the external tooth engagement that can slow down the external tooth engagement of left inside tooth 31 and left gear 2 and right inside tooth 32 and right gear 4 prevents that gear is damaged, the relevant transmission part of protection.
The working principle of the utility model clutch: middle gear 3 rotates with external driving gear engagement; If left gear 2 and right gear 4 are respectively by left inside tooth 31 and right inside tooth 32 and middle gear 3 tablings, then middle gear 3 drives left gear 2 and right gear 4 rotations simultaneously, left gear 2 and right gear 4 by external gear, are gone out transmission of power respectively, and this is the bonding state of clutch.Under the effect of clutch shifter (not shown), among left gear 2 or the right gear 4 one is separated with middle gear 3, then wherein still that gear rotation of engagement of 3 drives of middle gear, that gear that has broken away from has not just rotated, and power is gone out by that gear transmission of engagement; This is the part bonding state, can be used for the turning of traveling gear.If under the clutch shifter effect, left gear 2 and right gear 4 all are separated with middle gear 3, and then left gear 2 and right gear 4 have not rotated, and power has just blocked, and can not outwards transmit; This is the separated state of clutch.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
