Upper mechanism.Reducer output shaft 110 is fixedly installed on the second ring gear 90, for connecting with mechanism driving on the switch cubicle
Connect, such as pass through clamping engagement.Specifically, it is provided with a socket 111 on reducer output shaft 110, mechanism on switch cubicle
Working end is pluggable in the socket.The periphery wall of first ring gear 60 is provided with a pawl pockets 61, the spine of detent mechanism 120
Pawl 121 is overlapped on the periphery wall of the first ring gear 60, ratchet 121 and its spine of first ring gear 60 by detent mechanism 120
The cooperation of pawl neck 61 is braked to realize, i.e., when ratchet 121 inserts pawl pockets 61, the first ring gear 60 stops operating.The
The periphery wall of two ring gears 90 is provided with a groove 91, and the contact 131 of microswitch 130 is overlapped on the periphery of the second ring gear 90
On wall, microswitch 130 is connected with the switch of motor 10, for being disconnected in its 131 alignment indentation 91 of contact to close motor
10.That is, when the position where the groove 91 of the second ring gear 90 turns to contact 131, the ring gear 90 of contact 131 and second is not
Contact, microswitch 130 disconnect, and then close motor 10.
In addition, decelerator 1 also includes the first supporting plate 140, the second supporting plate 150 and for by the and of the first supporting plate 140
Some support columns 160 that second supporting plate 150 is releasably secured together.Specifically, support column 160 is bolt arrangement, the
Installation through-hole is provided with one supporting plate 140 and the second supporting plate 150, support column passes through installation through-hole, then locked with nut,
The first supporting plate 140 and the second supporting plate 150 are fixed together with realizing.First supporting plate 140 and the second supporting plate
150 be used for support, limit electric machine 10, driving gear 20, driven gear 30, reducer input shaft 40, the first ring gear 60, second
Ring gear 90, reducer output shaft 110, detent mechanism 120 and microswitch 130 etc..First supporting plate 140 is provided with motor 10
Output shaft 11 and reducer input shaft 40 resigning hole 141 and 142, the second supporting plate 160 is provided with reducer output shaft 110
Resigning hole 151.
In the present embodiment, detent mechanism 120 includes ratchet 121, action bars 122, spring 123 and spring fixed column 124,
Action bars 121 can be rotatably arranged between the first supporting plate 140 and the second supporting plate 150, and one is formed with ratchet 121.But
In other embodiments, ratchet 121 can also be formed separately with action bars 122, be then fixed together.Spring is fixed
Post 124 is fixedly installed in the second supporting plate 150, and its end is provided with groove.The end of spring 123 1 is connected on spring fixed column 124
It is another to terminate on action bars 122 on groove, for example, opening 1221 is connected to, for enabling ratchet 121 to be overlapped on first
On ring gear 60.Certainly, spring fixed column 124 can also be fixed in the first supporting plate 140 or be fixed on the first supporting plate 140
In the second supporting plate 150, the form of similar support column 160, and in the groove for being provided with clamping spring.
Illustrate the operation principle of decelerator 1 referring now to Fig. 5.When motor 10 works, its output shaft 11 rotates, and drives and fixes
Driving gear 20 thereon is rotated, and driving gear 20 engages with driven gear 30, and rotation is delivered into driven gear 30, driven
Gear 30 is fixed on reducer input shaft 40, to drive the central gear 50 being fixed on reducer input shaft 40 to rotate, too
Positive gear 50 is as the rotating speed of driven gear 30.When the ring gear 60 of ratchet 121 and first departs from, epicyclic train is differential
Gear train, reducer output shaft 110 (the second ring gear 90) are braked in the presence of service load, and the first ring gear 60 dallies.
Braked when the first ring gear 60 goes to certain angle by ratchet 121, i.e. ratchet 121 inserts pawl pockets 61.Double-planetary gear
As planet carrier 80 revolves round the sun around sun gear 50, direction rotating speed is identical.Due to the gear ratio and the of the first planetary gear reducing mechanism
The gear ratio of two planetary gear reducing mechanisms is different, thus need by the second ring gear 90 come compensate gear ratio different band come
The speed difference of two groups of planetary gear rotations, so it is achieved that the speed change of reducer input shaft 40 and reducer output shaft 110.It is logical
Cross the gear ratio for changing two planetary gear reducing mechanisms, you can obtain reducer input shaft 40 and reducer output shaft 110
Different gear ratio in wide scope.When the groove 91 of the second ring gear 90 goes to the contact 131 of microswitch 130, i.e., second
When ring gear 90 does not contact with contact 131, motor 10 is closed, decelerator 1 is stopped.
To sum up, ratchet planetary reducer of the present utility model is compact-sized, and overall volume is small, particularly suitable for peace
Dress space is small, in the switch cubicle of gear ratio high (can reach 5000).
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, is not departing from the spirit and scope of the present utility model that appended claims are limited, in form and details
On the utility model can be made a variety of changes, be the scope of protection of the utility model.
