Description
Technical field
The utility model belongs to dynamo-electric manufacturing field, particularly a kind of counting assembly for load ratio bridging switch motor drive mechanism record number of run and the record rotation number of turns.
Background technology
At present, the load ratio bridging switch motor drive mechanism realizes that the device of counting has electronic type counting and mechanical type counting, and the electronic type counting is comprised of electronic devices and components and battery, and needs the installation microswitch to provide run signal to count.The realization cost is high, and working time is short, and internal electromagnetic has consumed and just do not shown and record; The structures such as mechanical type counting adopts that disc type is stirred, connecting rod or lever realize, need with part complicated, the assembling trouble.
The utility model content
For overcoming defects, the technical problems to be solved in the utility model provides a kind of permanent mechanical type counting assembly of counting accurately and use.
A kind of mechanical counting device, this counting assembly comprises: gear one, gear two, gear three, gear four, upper mounting plate, lower installation board, back shaft, mechanical counter, spring, screw one, nut, bullet pad, rocking arm, screw two; The two ends of gear one, gear three, gear four is equipped with Step Shaft, is used for being fixed between upper mounting plate and the lower installation board, and gear one, gear two, gear four can only be rotated; Gear two rivetings guarantee that gear two and gear three are synchronous on gear three; Back shaft is fixed on the lower installation board; Mechanical counter is fixed on the upper mounting plate, and an end of spring is connected with mechanical counter, and the other end is connected with rocking arm by screw one, nut, bullet pad; Rocking arm is fixed on the gear four lower end circular shafts by screw two;
When counting, gear one rotate 1 circle for the conversion of load ratio bridging switch tap once, gear one rotation 1 astragal moving gear two, gear three, gear four also rotate 1 circle, gear four drives rocking arm and rotates 1 circle when rotating, tool counter closest approach forwards the solstics to by disembarking, rocking arm on the spring pulling mechanical counter rotates 38 °～40 ° countings 1 time, then forwards the closest approach spring reset from the solstics to and prepares counting next time.
The utility model adopts the structure of the formula mode of turning a millstone, and counting assembly does not need to show and storage with battery, can use for a long time, and is simple in structure, easy to assembly, reliable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the front view of the utility model counting assembly;
Fig. 2 is the vertical view of the utility model counting assembly.
Embodiment
Load ratio bridging switch is a vitals in the transformer, mainly plays transformation.Motor drive mechanism is again a vitals in the load ratio bridging switch, and counting assembly is a significant components in the motor drive mechanism.
As shown in Figure 1 and Figure 2, the utility model counting assembly comprises: gear 1, gear 22, gear 33, gear 44, upper mounting plate 5, lower installation board 6, back shaft 7, mechanical counter 8, spring 9, screw 1, nut 11, bullet pad 12, rocking arm 13, screw 2 14.Gear 1, gear 33, gear 44 two ends are processed with circular shaft and car has step, and gear 22 rivetings guarantee that gear 22 and gear 33 are synchronous on gear 3.Processing is porose on upper mounting plate 5 and the lower installation board 6, and upper mounting plate 5 is clamped gear 1, gear 33, gear 44 two ends Step Shafts with lower installation board 6, and circular shaft is loaded on to be installed in the plate hole, and its limiting gear 1, gear 33, gear 44 can only be rotated.Back shaft 7 is fixed on the lower installation board 6.Mechanical counter 8 is fixed on the upper mounting plate 5, and an end of spring 9 is fixed on the mechanical counter 8, and the other end is connected with rocking arm 13 by screw 1, nut 11, bullet pad 12.Rocking arm 13 is fixed on the gear 44 lower end circular shafts by screw 2 14.
Gear 1 rotate 1 circle for the conversion of load ratio bridging switch tap once, namely move 1 grade, gear 1 rotates 1 astragal moving gear 22, gear 33 rotates, gear 22 rotates driven gear 44 when driving other gear rotation, gear 44 is the same with gear one 1 numbers of teeth, modulus, thereby gear 44 also rotates 1 circle.Rocking arm 13 is fastening by screw 2 14 with gear 44, guarantees that rocking arm 13 and gear 44 rotate synchronously.Mechanical counter 8 upper springs 9 are connected with rocking arm 13 by screw 1, nut 11, bullet pad 12.Rocking arm 13 rotates 1 circle, forwards the solstics to by tool counter 8 closest approaches of disembarking, and the rocking arm on the spring 9 pulling mechanical counters 8 rotates 38 °～40 ° countings 1 time, then forwards closest approach spring 9 from the solstics to and resets and prepare counting next time.
Screw 2 14 is fastening at last in assembling, having debugged first the load ratio bridging switch motor drive mechanism is the tap position section start, be that gear indication indication is on red line, and then trip bolt 2 14, purpose is that mechanical counter spring 9 is free state when ensuring the on-load shunting switch motor drive mechanism and not moving, also can guarantee mechanical counter 8 when tapping switch electric rises or descend in the specialized range inside counting.
