Five, embodiment:

From Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 is as can be known: the utility model is mainly by support 1, spring 2, snap ring 3, rolling bearing 4, nut 5, bolster 6, external conical sleeve 7, setting nut 8, lining 9, inner conical drogue 10, dial gauge 12, gauge stand 13, detection ring 14 is formed, wherein 15 is sprocket wheel, 11 are the amount post, in sprocket wheel 15 testing processes, use, 14 is detection ring, in the utility model accuracy test, use, it is characterized in that: dial gauge 12 is installed in support 1 top by gauge stand 13, the middle part level of support 1 is connected with bolster 6, be set with rolling bearing 4 on the bolster 6, rolling bearing is set with external conical sleeve 7 on 4 outer rings, be set with the inner conical drogue 10 of inner cone cylindrical on the male cone (strobilus masculinus) of external conical sleeve 7, one end of inner conical drogue 10 is provided with positioning step, snap ring 3 is housed in the groove of the other end, and the outside of inner conical drogue 10 groove ends is spacing by the setting nut 8 that is installed on the external conical sleeve 7 by lining 9.The outer cone of external conical sleeve 7 is consistent with the inner cone tapering of inner conical drogue 10, and contact area is greater than 85%.

As can be seen from Figure 1: be set with two rolling bearings 4 on bolster 6, clamp external conical sleeve 7 between two rolling bearings 4, the both sides of rolling bearing 4 are spacing by step on the bolster 6 and nut 5.The radial and axial gap of nut 5 adjustable bearings 4.

From Fig. 1 also as can be known: the endoporus of described external conical sleeve 7 is the step of one section projection, and this step is installed between two rolling bearings 4.

From Fig. 4, Fig. 5 as can be known: inner conical drogue 10 is surrounded by 3 lobe arc pieces 16, leaves the gap between the arc piece.

From Fig. 6, Fig. 7 as can be known: snap ring 3 is made of two semicircular ring, and hoop has spring 2 in the annular groove of snap ring 3.Spring 2 can make inner conical drogue 10, snap ring 3 not be integral and can be scattered, three lobes that guaranteed inner conical drogue 10 simultaneously move synchronously, the endoporus of snap ring 3 and inner conical drogue 10 channel bottoms leave the 2mm gap, make the inner conical drogue 10 diameters big 2mm that can rise, to satisfy the needs that the sprocket wheel mounting hole changes.

As can be seen from Figure 2: be with detection ring 14 on the cylindrical of inner conical drogue 10.

The utility model is work like this, at first, can test the utility model precision: detection ring 14 is enclosed within on the cylindrical of inner conical drogue 10, the positioning step end face of being close to inner conical drogue 10, mobile setting nut 8 is moved to the left inner conical drogue 10, at this moment inner conical drogue 10 cylindricals rise big to closely contacting with detection ring 14 endoporus, the gauge outfit of adjusting the dial gauge 12 on support 1 top contacts with detection ring 14 cylindricals or end face, rotates detection ring 14, and the changing number of dial gauge 12 is the margin of error of this device; After detecting the error of this device, then can use this device that sprocket wheel is detected: the mounting hole of sprocket wheel 15 is enclosed within on the cylindrical of inner conical drogue 10, and be adjacent to the positioning step end face of inner conical drogue 10, setting nut 8 moves to left, the mounting hole of inner conical drogue 10 cylindricals and sprocket wheel 15 is fitted tightly, choose suitable amount post 11, to measure post 11 is placed in the different teeth groove of sprocket periphery and is adjacent to dedendum circle, the gauge outfit of adjusting dial gauge 12 contact with amount post 11 cylindricals, rotating sprocket back and forth, and each measuring point numerical difference between of dial gauge demonstration is sprocket tooth root and justifies radial beat eccentricity, gauge outfit with dial gauge 12 contacts with sprocket wheel 15 end faces again, rotating sprocket 15, the numerical difference between that dial gauge shows is sprocket wheel face runout amount, after detection finishes, withdraw from setting nut 8, inner conical drogue 10 its cylindrical that moves to right dwindles, and takes off sprocket wheel, finishes sprocket wheel and detects operation.
