Description
Technical field
The invention belongs to fields of measurement, relate in particular to a kind of measurement mechanism of measuring the little rotating torque of bearing.
Technical background
Bearing is widely used in engineering goods, and the dirigibility that aviation accessory product centre bearer part rotates has at work directly determined the running accuracy of bearing assembly.Referring to Fig. 1 and Fig. 2, require in product design to check that the rotating torque of governor weight assembly head bearing should be less than 0.004N.m, namely be not more than under this moment, piece number 2 can rotate with respect to piece number 1, because it is very little that rotating torque requires, be the sensitivity that check bearing rotates, measuring rotating torque with common torque spanner can not reach, so must there be special tooling to solve this type of problem.
Summary of the invention
In order to solve the above-mentioned technical matters that exists in the background technology, the invention provides a kind of simple in structure, detection efficiency is high and the measurement mechanism of the applicable on-the-spot little rotating torque of producing in batches of measurement bearing.
Technical solution of the present invention is: the invention provides a kind of measurement mechanism of measuring the little rotating torque of bearing, its special character is: the measurement mechanism of the little rotating torque of described measurement bearing comprises counterweight, balance stem and Coupling Shaft; Described counterweight is arranged on an end of balance stem; Described Coupling Shaft is arranged on the balance stem; Described Coupling Shaft upper edge also is provided with latch perpendicular to the direction of balance stem.
Above-mentioned counterweight is fixedly installed on the balance stem or is slidingly arranged on the balance stem.
Adopt between above-mentioned counterweight and the balance stem and flexibly connect.
Above-mentioned counterweight is fixed weight or adjustable counter balance.
Above-mentioned Coupling Shaft is fixedly installed on the balance stem or is slidingly arranged on the balance stem.
Above-mentioned Coupling Shaft upper edge is provided with pilot hole perpendicular to the direction of Coupling Shaft, and correspondence is provided with pin-and-hole on the described balance stem, and described Coupling Shaft is connected with balance stem by the dowel hole and pin hole.
Pin-and-hole on the above-mentioned balance stem is one or more.
When the pin-and-hole on the above-mentioned balance stem was a plurality of, pin-and-hole was distributed on the balance stem.
Above-mentioned balance stem is provided with scale.
Advantage of the present invention is:
The fine detection requirement that has solved bearing assembly of the twisting device of the little rotating torque of measurement bearing provided by the present invention, only comprise Coupling Shaft, balance stem and counterweight, be similar to steelyard, simple in structure, in use, the present invention directly is connected on the part, whether judges whether to meet rotating torque according to the rotation of part, easy to use; And before using, at first moment is calculated, to implement to adjust on the basis of calculating, measurement result is reliable, stable, and the detection efficiency height is suitable for on-the-spot batch process the in batches.

Embodiment
The invention provides a kind of special measurement instrument, especially measure the measurement mechanism of the little rotating torque of bearing, the measurement mechanism of the little rotating torque of this measurement bearing comprises counterweight 3, balance stem 2 and Coupling Shaft 1; Counterweight 3 can be fixedly installed on the balance stem 2, also slidably be arranged on the balance stem 2, be that counterweight 3 can be slided along balance stem 2, the slip set-up mode can be adjusted the position of counterweight 3 on balance stem 2 according to actual needs, when counterweight 3 is arranged on the balance stem 2, can be by bolt together, perhaps directly fix by screw thread.Counterweight 3 can be the counterweight of fixed weight, also the adjustable counterweight of weight.Coupling Shaft 1 is arranged on the balance stem 2, and a side of counterweight 3 can be fixedly installed on the balance stem 2, also slidably is arranged on the balance stem 2, and namely Coupling Shaft 1 can be slided along balance stem 2; Coupling Shaft 1 upper edge is parallel to Coupling Shaft 1 and is provided with latch 6 perpendicular to the direction of balance stem 2, the width of the C position display of the width of latch 6 and piece number 2 is the same, the width of the B position display of the thickness of Coupling Shaft 1 and piece number 2 is the same, during use, Coupling Shaft 1 is placed the B position of piece number 2, latch 6 directly is connected on the C position of piece number 2 simultaneously, can measure rotating torque then.
For easy to use, be provided with pilot hole 5 on the Coupling Shaft 1 and along the direction perpendicular to Coupling Shaft 1, correspondence is provided with pin-and-hole 7 on the balance stem 2, and the purpose of pin-and-hole 7 is the distances for the center of adjusting Coupling Shaft 1 at any time, in order to adjust at any time with the centre distance of counterweight 3.The number of this pin-and-hole 7 can be one or more, during a plurality of pin-and-hole 7, use more convenient, if 7 of a pin-and-hole will be adjusted Coupling Shaft 1 at any time in the distance of balance stem 2, no matter be one or a plurality of pin-and-hole 7, its purpose all is consistent, all is in order to obtain the distance of Coupling Shaft 1 and counterweight 3, and calculates its moment according to this distance.
The present invention also is provided with scale for better effects if on balance stem 2, this scale very the aspect, very intuitively the distance of counterweight 3 is adjusted so that and the distance between the Coupling Shaft 1 carry out at any time accommodation in real time.
The present invention in use, at first require (as 0.004N.m) to calculate the counterweight center of counterweight 3 to the distance at the center of Coupling Shaft 1 and the weight of counterweight 3 according to moment, mix up counterweight 3 distances, after making its moment be 0.004N.m, the corresponding site that the latch of being with on the Coupling Shaft 1 of the present invention 6 directly is connected in part cooperates, and whether judges the size of moment of torsion by the rotation of part.If piece number 2 can freely rotate in the part, then rotating torque meets the requirement of part; If piece number 2 can not rotate in the part, then rotating torque does not meet the requirement of part.The present invention need calculate in use, and strict guarantee instrument two ends are reduced error for the symmetry at center with this.Be applicable to that the on-the-spot little moment of torsion of bearing that detects rotates needs.
