The torque measuring device of active driving mechanism

Technical field

The utility model relates to the torgue measurement of active driving mechanism, especially a kind of torque measuring device of active driving mechanism of capable eliminating additional power.

Background technology

Concerning active driving mechanism, for grasping the performance parameter of mechanism reliably, exactly, need carry out the moment test to mechanism, at present, two kinds of proving installations are arranged according to the size of load inertia:

(1) when load inertia hour, employing directly connects the output shaft of mechanism with the inertia dish of fictitious load, add counterweight by rope in inertia dish one side, and this proving installation has been ignored the additional force of test inertia dish to mechanism, therefore, can not eliminate the additional force of inertia dish fully.

(2) when load inertia is big, adopt the mode that below the inertia dish, increases brace table to offset additional force.Though this proving installation can be eliminated additional force fully, the installing space size and the direction of experimental measurement equipment (as vacuum tank etc.) are had relatively high expectations.

The utility model content

For the torque measuring device of the active driving mechanism that solves prior art can not be eliminated additional force when the test fully, perhaps bulk that experimental measurement equipment is installed and direction problem such as have relatively high expectations, the purpose of this utility model is to provide a kind of torque measuring device of active driving mechanism, utilize the utility model, can eliminate fully in the measuring process issuable all additional forces of mechanism, can adapt to new space layout demand simultaneously.

In order to reach above-mentioned utility model purpose, the utility model is the torque measuring device that technical scheme that its technical matters of solution is adopted provides a kind of active driving mechanism, and this device comprises:

Active driving mechanism product to be measured is installed on the test support; Load simulation inertia dish horizontal positioned, the output shaft of the product to be measured of its center pit and below passes through key connecting; The both sides of load simulation inertia dish respectively are provided with a fixed pulley, and these two fixed pulleys are rack-mount; Load simulation inertia dish is fixed with rope towards the periphery place of fixed pulley; An other end of two ropes is walked around back carrying counterweight pulling force from the fixed pulley of both sides respectively.

The torque measuring device of a kind of active driving mechanism of the utility model, owing to take above-mentioned technical scheme, the output shaft of inertia dish horizontal positioned and active driving mechanism to be measured is passed through key connecting, guarantee that the counterweight in the vertical direction has enough spaces, utilize the couple principle to eliminate the additional force that mechanism is produced.Compared with prior art, the beneficial effects of the utility model are: can eliminate frock and the load additional force to product fully, can adapt to different space mounting requirements simultaneously.
