Direct drive torque detection mechanism

Abstract

The invention discloses a direct transmission group torque detection mechanism, which is characterized in that: the direct transmission group torque detection mechanism is fixedly installed on the assembly platform of the direct transmission group assembly device; the direct transmission group torque detection mechanism includes a clamp for rotation , a rotary driver and a rotary parameter acquirer, wherein the rotary clamp is used to clamp the protruding part of the upper section of the direct drive shaft sleeve inserted into the assembly seat of the direct drive assembly device; the rotary drive includes a motor and a rotating rod, The rotating rod rotates synchronously with the rotating shaft of the motor, and the rotary driver is used to drive the driving rod and the transmission shaft of the direct transmission group inserted on the assembly seat to rotate through the rotating rod; the rotation parameter acquirer is used to measure the rotation parameters of the transmission shaft of the direct transmission group. The torque detection mechanism of the direct transmission group of the present invention can directly complete the torque detection on the assembly device of the direct transmission group, and can help improve the efficiency of assembly and detection.

Description

technical field [0001] The invention belongs to the field of gas meters, and in particular relates to a torque detection mechanism of a direct transmission group. Background technique [0002] The diaphragm gas meter is mainly composed of a metering part (including two metering boxes with flexible diaphragms inside each), a transmission part (including a diaphragm, a folding plate, a vertical shaft, a rocker arm, a connecting rod, a crank, a shift fork and a valve cover) ), the counting part and the housing. [0003] The working principle of the membrane gas meter is: a diaphragm (usually made of synthetic rubber) is sealed at the center line of each metering box, and the diaphragm divides the inside of the metering box into two metering gas chambers. After the gas enters the gas meter, it alternately enters the two metering gas chambers of each metering box, so that the diaphragm (and the diaphragm clamped on the diaphragm) reciprocate, and then the linkage is realized—the...

Problems solved by technology

[0005] The magnetic transmission device drives the rotation of the inner magnetic sleeve through the rotation of the outer magnetic sleeve, thereby outputting the rotational kinetic energy to the outside. However, the magnetic transmission device has many components, and the assembly and transmission between the components are more complicated. The magnetic sleeve is placed on the outside of the inner magnetic sleeve, so it still has the disadvantages of heavy weight, large volume, and difficulty in miniaturization. At the same time, because the outer magnetic sleeve and the inner magnetic sleeve are magnets, they are not resistant to strong magnetic interference and are prone to appear in a magnetic environment. The transmission accuracy is poor; moreover, it is easy to cause errors in the instrument measurement due to the artificial magnetic environment (air stealing phenomenon)
