Ring gear, the lower plate in annular shape that can be set on the outside of sprocket wheel are set on inwall；
The upper plate fixed with the lower plate, the top at the upper plate center set the torsion boss for protruding from upper surface, institute
The center for stating torsion boss opens up square groove.
Preferably, upper plate position corresponding with the lower plate opens up bolt hole respectively, and inside sets internal thread, leads to
Bolt is crossed to fix both.
Preferably, the upper plate opens up four respectively with the bolt hole in the lower plate, is evenly distributed in edge.
Preferably, the square groove insertion setting reversed boss center and opened up.
Preferably, the upper plate is identical with the thickness of the lower plate.
Preferably, the upper plate and the thickness of the lower plate are all higher than the thickness of detected sprocket wheel.
Preferably, the side wall for the square groove being arranged on the torsion boss is machined surface.
Sprocket wheel torque-measuring apparatus provided by the present invention, there is body, body is in step-like, and centre sets fluting, because
This is irregular tubular.The bottom of body opens up mounting groove, and ring gear is set on the inwall of mounting groove, and ring gear can be with quilt
The device of detection is meshed, and sets square groove at the top of body, is inserted for coordinating with torque wrench.By institute in the present invention
The measurement apparatus of offer need not simultaneously clamp to sprocket wheel, it is not necessary to frictional force transmit torque, but using being meshed by the way of and
Sprocket wheel is engaged, and will not be occurred to slide relatively between the two, be ensure that fixed validity.

Embodiment
The present invention core be to provide a kind of sprocket wheel torque-measuring apparatus, the device ensures will not be sent out during moment of torsion transmission
Raw relative slip, it is ensured that fixed validity.
In order that those skilled in the art more fully understands sprocket wheel torque-measuring apparatus provided by the present invention, below will
Technical scheme is described in detail with reference to accompanying drawing and specific embodiment.
As shown in figure 1, it is a kind of structure chart of embodiment of sprocket wheel torque-measuring apparatus provided by the present invention.Include and be in
Step-like body 1, the inside of body 1 have fluting, therefore are in irregular tubular, and bottom sets mounting groove, with sprocket wheel
External toothing matches, as shown in Fig. 2 the profile being engaged for measurement apparatus with sprocket wheel.Set at the top of body 1 square
Groove, it can insert and coordinate with torque wrench.Measurement apparatus provided by the present invention need not be clamped sprocket wheel, but by nibbling
The mode of conjunction mutually fixes measurement apparatus with sprocket wheel, transmits twisting resistance not by frictional force both when applying moment of torsion, but
By mechanical engagement, therefore it is able to ensure that the validity of connection.
As shown in Figure 3 and Figure 4, respectively upper plate 12 and lower plate 11 are located at the top view at Fig. 1 visual angles.In order that measurement apparatus
It is easy to manufacture, body 1 is divided for two parts, a part is lower plate 11, and in circular ring, internal tooth is set on inwall
Circle, for being sleeved on the outside of sprocket wheel.Another part is the upper plate 12 with the phase secure fit of lower plate 11, can be made respectively in production
Make, it is convenient that ring gear in lower plate 11 is processed.Set at the top at the center of upper plate 12 and reverse boss 121, reverse boss
121 are higher than the upper surface of upper plate 12, open up square groove at the center for reversing boss 121, need one after being inserted due to torque wrench
Fixed length, therefore there is provided reverse boss 121.Specifically, reversing the inwall of boss 121 needs and applies the moment of torsion of twisting resistance
Spanner is bonded to each other, therefore needs certain requirement, it is necessary to be arranged to machined surface to the precision of its inwall, general side in the present invention
The surface roughness of shape groove inwall is arranged to 1.6, and the surface accuracy of other parts is not defined.
Upper plate 12 needs to be fixedly connected with lower plate 11, and corresponding opening position opens up bolt respectively on upper plate 12 and lower plate 11
Hole, opens up internal thread in the inside of bolt hole, is fixed upper plate 12 and lower plate 11 using bolt during installation.Certainly, using other
Fixed form it is also possible, be not defined herein.In order to ensure the validity being connected, upper plate 12 is with
Plate 11 opens up four bolts hole respectively, is evenly distributed in the edge of upper plate 12 and lower plate 11.
In addition, in order to reach the purpose of mitigation measurement apparatus weight, the square groove that torsion boss 121 center opens up is penetrated
Set, reduce the material used.Further, upper plate 12 needs to ensure same intensity with lower plate 11, therefore may be configured as identical
Thickness, and both thickness is required to be more than detected sprocket wheel, and in detection, lower plate 11 needs whole sprocket wheel being sleeved on
Interior, in the vertical direction can allow some deviations.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle, it can realize in other embodiments without departing from the spirit or scope of the present invention.Therefore, this hair
It is bright to be not intended to be limited to the embodiments shown herein, and be to fit to and principles disclosed herein and features of novelty phase
Consistent most wide scope.
