Abstract
The utility model relates to a machine core transmission mechanism of a two-way gas measurement meter. The transmission mechanism comprises a bracket (2) and an automatic guide transmission mechanism which is arranged on the bracket (2); wherein, the automatic guide transmission mechanism consists of a driven wheel (4), a guide mediated wheel (9), a transmission wheel (8) and a transmission mediated wheel (6); the wheel axle (41) of the driven wheel (4) is arranged in an arc groove (20); the driven wheel (4) meshes with and matches a center gear (3); the guide mediated wheel (9), the transmission wheel (8), the transmission mediated wheel (6) and an output wheel (7) mesh with and match each other; and the driven wheel (4) meshes with and matches the transmission wheel (8) or the guide mediated wheel (9) under the effect of the center gear (3). When the gas meter is used for providing gas in the positive direction or in the negative direction, the utility model ensures that the rotating direction of the output wheel (7) can not be changed; thus the continuous positive metering of the gas meter is realized; the gas meter has the two-way metering function, and the utility model effectively prevents the gas user from stealing the gas through the reverse connection of the gas meter.
Description
Technical field
The utility model relates to gas meter, particularly the movement gear train of gas meter, flow meter.
Background technology
At present, traditional gas meter movement only is provided with anti-reversing gearbox, when the gas meter, flow meter reversal connection is ventilated, can prevent to be shown as counter reversing counter and not measure, but gas still can pass through, and promptly the combustion gas user still can continue to use gas.This gas meter, flow meter can not prevent that the user from will show reversal connection and stealing gas.
The utility model content
The purpose of this utility model is that the but deficiency of ventilation is not measured in reverse air inlet at above-mentioned traditional gas meter, flow meter, provide a kind of simple in structure, easily manufactured, can realize the gas meter, flow meter gas meter movement gear train no matter the forward ventilation still oppositely all can the forward metering during ventilation, thereby prevent from gas is stolen in the gas meter, flow meter reversal connection.
Technical solution of the present utility model is to be provided with the automatic guide gear train at central gear 3 and 7 of output wheels that four connecting rod a of gas meter movement drive, include support 2 and the supporting roller 4 that is installed on the support 2, guiding idle wheel 9, power wheel 8, transmission idle wheel 6 constitutes, support 2 is fixedly connected on the core body 1, it is in the arc groove 20 offered of the center of circle that the wheel shaft 41 of supporting roller 4 is slidingly mounted on the support 2 axle center 30 with central gear 3, supporting roller 4 and central gear 3 engagement fit, guiding idle wheel 9 and power wheel 8, power wheel 8 and transmission idle wheel 6, transmission idle wheel 6 is meshing with each other with output wheel 7 and cooperates, the wheel shaft 41 of supporting roller 4 two ends in arc groove 20 move make supporting roller 4 respectively with power wheel 8 or guiding idle wheel 9 engagement fit; When center gear 3 forward rotation, supporting roller 4 makes supporting roller 4 and power wheel 8 engagement fit moving under the drive of central gear 3 below arc groove 20, and supporting roller 4 drives power wheels 8, transmission idle wheel 6, output wheel 7 forward rotation and drives counter; Central gear 3 backward rotation when the gas meter, flow meter reversal connection is ventilated, supporting roller 4 makes supporting roller 4 and idle wheel 9 engagement fit that lead mobile above arc groove 20 under the drive of central gear 3, guiding idle wheel 9 drives power wheel 8, commutation through guiding idle wheel 9 makes power wheel 8 keep forward rotation to drive output wheel 7, guarantee that output wheel 7 rotation directions are constant, thereby realize gas meter, flow meter forward metering all the time.
The utility model is simple in structure, and is easily manufactured, reliable transmission, make gas meter, flow meter have the function of bidirectional measuring, promptly no matter the ventilation of gas meter, flow meter forward is still oppositely ventilated, and the gas meter, flow meter counter can both reach the forward metering, can prevent effectively that the combustion gas user from stealing gas with the gas meter, flow meter reversal connection.
