The utility model content
In order to solve the above-mentioned technical matters that exists in the background technology, the utility model provide 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 utility model is: the utility model provides a kind of measurement mechanism of measuring the little rotating torque of bearing, and 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.
The utility model has the advantages that:
The fine detection requirement that has solved bearing assembly of the twisting device of the little rotating torque of measurement bearing provided by the utility model, only comprise Coupling Shaft, balance stem and counterweight, be similar to steelyard, simple in structure, in use, the utility model 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, on the basis of calculating, to implement to adjust, measurement result is reliable, stable, and the detection efficiency height is suitable for on-the-spot batch process the in batches.

Embodiment
The utility model provides a kind of special measurement instrument, especially measures the measurement mechanism of the little rotating torque of bearing, and 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 together, perhaps directly fix by screw thread by bolt.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 promptly 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 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, so that 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 the distance of Coupling Shaft 1 at balance stem 2 at any time, 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 goes out its moment according to this distance calculation.
The utility model 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 utility model 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 utility model Coupling Shaft 16 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 utility model 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.
