Embodiment
Below in conjunction with drawings and Examples, technological scheme of the present invention is described in further detail.
A kind of main driven shaft disengaging gear as Figure 1-3, mainly comprises the joint unit 1 and breaking unit 2 that are connected; Wherein:
Joint unit 1 is mainly comprised joint 12 and is supported in the output shaft 10 in joint 12 by joint shaft bearing 11, and there is positioning spigot 15 one end in joint, for ensureing the coaxality of throwing off fixing frame and joint;
Blind hole is provided with, for being connected with the wheel shaft coupling of driving wheel 3 in first end face of output shaft 10; Other end is fixed with left chain wheel 13, and is also provided with blind hole in the end face being provided with left chain wheel 13, and blind hole is embedded with copper sheathing 14, and the input shaft of breaking unit embeds in copper sheathing 14, and output shaft 10 is connected with input shaft 20.
Breaking unit 2 mainly comprises throws off fixing frame 21 and is located at the output shaft 20 of throwing off in fixing frame,
One end (left end in Fig. 3) of output shaft 20 embeds in the copper sheathing of output shaft 10, the other end (right-hand member) is then supported in by input end bearing 28 throws off fixing frame 21 (in the mounting hole of input end bearing 28 embedding disengagement fixing frame 21, and carry out axial limiting by jump ring 30), and have blind hole in the end face on right side, for connecting with the output shaft of the motor reducer as power source, realize the reliable output of power;
Throw off fixing frame 21 to be connected with joint 12 by end flanges, achieve being connected of joint unit 1 and breaking unit 2;
Owing to extending axially through with the right chain wheel 22 of left chain wheel 13 engagement the outside that linear bearing 23 is supported in output shaft 20, spring 26 is enclosed within the dish axle of right chain wheel 22 vertically, and two ends fix with the spring block 25 be fixed on the right side of input shaft 20 respectively by the right side of left chain wheel 13;
Be provided with chock 24 between the dish shaft end of right chain wheel 22 and spring block 25, the part that axis body is stretched out at the two ends that radially penetration type is embedded into the optical axis pin 27 of input shaft 20 can be slided along in the chute of chock 24;
Right chain wheel 22, linear bearing 23 and chock 24 are fixed with one formation sliding assembly, can slide axially under the drive of linear bearing 23 along input shaft 20; And radial at input shaft 20, because penetration type is embedded into the slip of optical axis pin 27 in the chute of chock 24 of input shaft 20, limit sliding assembly rotating relative to input shaft 20;
The top of throwing off fixing frame 21 is provided with chute, can horizontally slip vertically at internal chute at the effect lower shift fork 29 of external force, by engagement or the disengagement of the telescopic band movable chain wheel (13,22) of spring 26, and then realize the joint of joint unit 1 and breaking unit 2 or be separated.
The working principle of disengaging gear of the present invention is:
If shift fork 29 under original state is left without External Force Acting, right chain wheel (13, 22) engage, the now rotation of motor reducer 4 can be with motor car wheel (driving wheel 3) to rotate, when External Force Acting makes it slide along the chute of throwing off fixing frame 21 to the right on shift fork 29, shift fork 29 drives the relative input shaft 20 of right chain wheel 22 to slide to the right, while spring 26 is compressed, left, right chain wheel (13, 22) end-tooth is thrown off immediately, now motor reducer 4 rotating band driven input shaft 20 rotates, the other end of input shaft 20 rotates relative to output shaft 10 in the copper sheathing 14 of output shaft 10, but due to a left side, right chain wheel (13, 22) throw off, so therefore output shaft 10 can not rotate, torque just cannot be delivered on the wheel shaft of driving wheel 3, that is, now motor reducer 4 rotates and driving wheel 3 can't be driven to rotate, namely the disengagement of driving shaft and driven shaft is achieved,
After acting on the disappearance of the external force on shift fork, extended by the spring 26 compressed, promote right chain wheel 22 to move to left, left and right chain wheel (13,22) is engaged again, torque can be delivered to again on wheel axle, driving shaft, driven shaft recover bonding state, and driving wheel 3 realizes rotating under the effect of motor reducer 4.
Disengaging gear of the present invention can realize the driving shaft of machine carriage, the combination of driven shaft and disengagement; In conjunction with time, dolly is in electric model, left and right chain wheel (13,22) engage, the motor reducer 4 as power source drives the driving wheel 3 of dolly to rotate; During disengagement, dolly is in manual mode, and left and right chain wheel (13,22) is thrown off, and the rotation even if motor reducer 4 powers on, also cannot drive driving wheel 3 to rotate, and equally, driving wheel 3 also cannot reverse by drive motor retarder 4.Thus ensure that the power reliable delivery when jointing state, do not produce resistance does not also cause motor damage because of anti-de-under disengaged condition.
Disengaging gear of the present invention as shown in Figure 4, is placed between the driving wheel 3 of baby carriage and motor reducer 4 by a kind of practical embodiments, is fixed with one with it in the blind hole that the wheel axle of driving wheel 3 is embedded in the output shaft 10 of joint unit 1; Be fixed with one with it in the blind hole that the output shaft of motor reducer 4 is embedded in the input shaft 20 of breaking unit 2; The end face of motor reducer 4 is connected by the disengagement fixing frame 21 of end flanges and breaking unit 2.
Below explain embodiments of the invention by reference to the accompanying drawings, accompanying drawing is herein used to provide a further understanding of the present invention.Obviously; the foregoing is only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; any be to one skilled in the art can expect easily, do not depart from change of the present invention or replacement in fact, be also all included within protection scope of the present invention.
