Fig. 1-8 show a novel centrifugal escapement speed stabilizing mechanism, which comprises an outer lock wheel 1, a lock bead 2, an inner lock wheel 3, a roller 4, a fixed side plate 5 and a pin 6. The external lock gear 1 is provided with internal teeth, the tooth tops of the internal teeth are in a triangular tooth shape, the tooth bottoms of the internal teeth can be in an arc shape or a triangular tooth shape, and the tooth number can be selected from 4-20 teeth according to the requirements of load size and rotating speed. The inner lock wheel 3 is arranged inside the outer lock wheel 1, a transmission shaft hole is formed in the center of the inner lock wheel 3 so as to be fixedly connected with other transmission parts to complete a speed stabilizing function, lock bead grooves are uniformly formed in the circumferential direction of the outer arc top of the inner lock wheel 3, lock beads 2 are arranged in the lock bead grooves, the number of the lock bead grooves is equal to that of the lock beads 2, the number of the lock bead grooves can be selected from 2-20 according to the requirements of load size and rotating speed, the number of the lock bead grooves is less than that of inner teeth of the outer lock wheel 1, and the shape of each lock bead groove is an envelope line formed when the lock beads 2 roll along the inner tooth grooves of the outer lock wheel 1. As shown in fig. 2-3, the lock bead 2 is composed of a roller 4, a fixed side plate 5 and a pin 6, the pin 6 penetrates through a central hole of the roller 4 and is fixedly connected to the fixed side plates 5 at two sides in a riveting mode, the roller 4 can freely rotate around the pin 6 to reduce collision abrasion of the lock bead 2 with the outer lock wheel 1 and the inner lock wheel 3, the lock bead 2 can move in an inner tooth groove of the outer lock wheel 1 and a lock bead groove of the inner lock wheel 3, the fixed side plate 5 is dumbbell-shaped, as shown in fig. 6, the second structure of the lock bead 2, and the fixed side plate 5 can also be kidney-shaped.
As shown in fig. 9-10, the third and fourth configurations of the locking bead 2, the locking bead 2 may also be a dumbbell-shaped sheet-like monolith or a "kidney" shaped sheet-like monolith.
Referring to fig. 7, in the second embodiment, 12 internal teeth are provided on the external lock wheel 1, five lock bead grooves are provided on the internal lock wheel 3, and the lock beads 2 are respectively provided in the lock bead grooves.
Referring to fig. 8, in the third embodiment, 12 internal teeth are provided on the external lock wheel 1, two adjacent lock bead grooves are symmetrically provided on the internal lock wheel 3, and the lock beads 2 are respectively provided in the lock bead grooves.
The above-mentioned embodiment is the adaptive design to different speed stable operating modes, and the distribution setting of lock pearl groove is relevant with load size and speed stability requirement.
The working principle is as follows:
in the working process, the outer lock wheel 1 is fixed, the inner lock wheel 3 is connected with the transmission shaft through the central shaft hole, the lock beads 2 are driven to rotate around the central shaft of the inner lock wheel 3 under the driving of the transmission shaft, and under the action of rotating centrifugal force, the lock beads 2 do reciprocating swing relative to the inner lock wheel 3 in the lock bead groove of the inner lock wheel 3 while tightly clinging to the inner wall of the tooth groove of the outer lock wheel 1 to roll.
In the clockwise rotation process of interior lock wheel 3, when lock pearl 2 was in the back position of interior lock wheel 3 lock pearl groove, as shown in fig. 4, the forward end roller of lock pearl 2 was not restricted by outer lock wheel 1 internal tooth, and this position is the "vertical" initial position of outer lock wheel 1 to lock pearl 2, and in this position department, lock pearl 2 can reach the forward position in lock pearl groove fast under the pushing action of interior lock wheel 3, and "vertical" in-process lock pearl 2 does not have the deceleration action to lock wheel 3.
In the clockwise rotation process of inner lock wheel 3, when lock ball 2 is in the forward end position of lock ball groove of inner lock wheel 3, as shown in fig. 5, the forward end roller of lock ball 2 is restricted by the collision of the inner teeth of outer lock wheel 1, and this position is the "catching" initial position of outer lock wheel 1 to lock ball 2, and in this position, the forward end roller of lock ball 2 is restricted by the collision of the inner teeth of outer lock wheel, and the backward end roller of lock ball 2 will produce the collision restriction to the lock ball groove of inner lock wheel 3, that is, outer lock wheel 1 produces indirect collision restriction to lock wheel 3 through the rotation of lock ball 2, and lock ball 2 swings slowly and reaches the backward end position of lock ball groove in this "catching" process, therefore, outer lock wheel 1 has obvious deceleration effect to lock wheel 3 through lock ball 2 in the "catching" process.
In the working process, the processes of catching and longitudinal are alternately generated, the lock bead 2 is forced to vibrate under the back-and-forth collision action of the outer lock wheel 1 and the inner lock wheel 3, the vibration period is related to the centrifugal force of the lock bead 2 and the torque of the inner lock wheel and the outer lock wheel, and the inner lock wheel 3 consumes a part of energy in the collision constraint process every time, so that the aim of stabilizing the speed is fulfilled. In addition, lock pearl 2 rotates along with interior lock wheel 3 in the lock pearl inslot, and the rotational speed is faster, and the centrifugal force of lock pearl 2 is bigger, receives the collision restraint effect of outer lock wheel 1 just more obvious, has reached the effect that effectively utilizes rotatory centrifugal force to strengthen steady speed.
When the internal lock wheel 3 rotates anticlockwise, the processes of 'catching' and 'longitudinal' still occur alternately due to the completely symmetrical mechanical structure of the invention, so the invention has the same function of stabilizing speed, and also effectively utilizes the rotating centrifugal force to enhance the speed stabilizing effect, namely the novel centrifugal catching type speed stabilizing mechanism has the forward rotation function and the reverse rotation function with the same effect.
