Embodiment
Below provide specific embodiment of the utility model, it should be noted that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as shown in Figures 1 to 4, the present embodiment provides a kind of counting assembly for high-speed computation, comprise input shaft 1, on input shaft 1, be installed with revolution wheel 2, on the input shaft 1 of revolution wheel 2 one sides, be fixedly installed the first gear 4, the first gear 4 engages with the second gear 5, the second gear 5 is installed with one heart the 3rd gear 7, the three gears 7 by intermediate shaft 6 and engages with the 4th gear 8, and the ratio of gear between the first gear 4 and the 4th gear 8 is 10:1;
The 4th described gear 8 rotary types are arranged on revolution and take turns on the input shaft 1 of 2 opposite sides, the 4th gear 8 is provided with counter wheel 3 away from rotary type on the input shaft 1 of a side of revolution wheel 2, counter wheel 3 is fixedly installed ratchet 9 on the side near the 4th gear 8, on ratchet 9, be engaged with and control the pawl bar 10 that ratchet 9 rotates, in the lateral edge of revolution wheel 2 near ratchet 9, be provided with and can make pawl bar 10 depart from the unhook pin 11 of ratchet 9;
On described ratchet 9, be processed with 10 identical sawtooth, on described counter wheel 3, be processed with torsional spring working chamber 12 near on the side of ratchet 9, torsional spring 13 is installed in torsional spring working chamber 12, one end of torsional spring 13 is connected with the first bearing pin 14-1, the other end of torsional spring 13 is connected with the second bearing pin 14-2, the first bearing pin 14-1 is fixedly installed on counter wheel 3, and the second bearing pin 14-2 is fixedly connected on the 4th gear 8 through the deep-slotted chip breaker 15 that connects ratchet 9 on ratchet 9.
The 4th gear 8 is arranged on input shaft 1 by bearing 17 rotary types, and described counter wheel 3 is arranged on input shaft 1 by bearing 17 rotary types.
On pawl bar 10, be provided with pouring weight 16.
The course of work of the present utility model is as described below:
As shown in Figure 1, when counting assembly work, revolution wheel 2 is connected as a single entity by key and input shaft 1, revolution wheel 2 rotations along with input shaft 1 and rotating, and the rotation of the 4th gear 8 equals revolution and takes turns 1/10th of 2 rotating speed through the transmission of the 1st gear 4, the second gear 5 and the 3rd gear 7.
The second bearing pin 14-2 is fixedly connected on the 4th gear 8 through the deep-slotted chip breaker 15 that connects ratchet 9 on ratchet 9, the first bearing pin 14-1 is fixedly installed on counter wheel 3, they engage with two bent-up ends of volute spring 13 respectively, and their integral installations are in the middle of volute spring working chamber 12.In the time that the 4th gear 8 rotates, although due to the connection of volute spring 13, the trend of rotating together with counter wheel 3 has with the 4th gear 8, the pawl bar 10 connecting with ratchet 9 phase hooks has stoped the rotation of counter wheel 3.Ratchet 9 is mounted on counter wheel 3.Therefore, making counter wheel 3 rotate required energy is stored with the potential energy form of volute spring 13.On the side of revolution wheel 2, a little unhook pin 11 is housed, when revolution wheel 2 often circles, unhook pin 11 just contacts pawl bar 10 once, and in the moment of contact, pawl bar 10 is depressed.Pawl bar 10 departs from ratchet 9, and counter wheel 3 is no longer fettered by pawl bar 10, makes counter wheel 3 under the effect of the screen resilience of volute spring 13, rotates 1/10th weeks, until pawl bar 10 and ratchet 9 again hook be linked as and stop.
In the time that the demonstration on counter wheel 3 is inaccurate, can control by the size of the pretightning force of adjustable screw spring 13 relation of the rotating speed 10:1 of revolution wheel 2 and counter wheel 3, and can on pawl bar 10, impose a slight additional weights 16 simultaneously, can stop like this pawl bar 10 to get back to ratchet 9 and get on, thereby make the counter wheel 3 can smooth rotation.Like this, this reading of taking turns of correction that operator just can be random.The utility model is by the energy-storage function of torsional spring 13, making between the 4th gear 8 and counter wheel 3 to realize has flexibly connecting of buffering, can overcome along with running up of turning up to per minute 12000 and the approximately load of 0.007N.m and the shock problem that produces the in the situation that of high-speed computation.
