The present invention can independently be complete double-side gear rolling tester for bevel gear, also can increase two-sided engagement measuring ability on general bevel gear rolling inspection machine.
Referring to accompanying drawing, the present invention includes base 3, base 3 is provided with the adjustable main drive shaft 1 of relative position, main drive shaft axle bed 1a and driven axle 2, driven axle axle bed 2a, be provided with linear rolling track 2b between driven axle 2 and the driven axle axle bed 2a, driven axle 2 both can be rotated on driven axle axle bed 2a, can do limited moving along this linear rolling track 2b again.
The radial error of bevel gear detects not have at tested gear carries out roll detection under the sideshake engagement.For this reason, the present invention also is provided with the orientation adjustment device 2d of driven axle 2, and in the present embodiment, this orientation adjustment device 2d is along the axial spring of driven axle.
Driven axle of the present invention comprises a core and axle sleeve, described axle core and axle sleeve are fixedly linked, and this spring 2d one end and driven axle axle bed 2a are fixedly linked, and the other end and this axle sleeve are fixedly linked, be subjected to the pulling force of this orientation spring, make driven axle remain no sideshake engagement.
The present invention also is provided with the detent mechanism of driven axle axle bed, is used for the installation of tested gear.
This detent mechanism comprises the groove and the locator card arm of being located on the driven axle axle sleeve be located on the driven axle axle bed 2a, and this card arm can rotate.When the present invention brings into use, when driven axle is transferred to the engagement of no sideshake, should block arm and rotate and snap in the described groove, the moving axially of pinning driven axle.By the time begin to detect, should block arm and in groove, screw out, can unclamp detent mechanism, begin test.
Driven axle 2 is provided with clock gauge or pen recorder.This clock gauge or registering instrument can be located at the position of conveniently detecting on the driven axle 2.This clock gauge or pen recorder (registering instrument) can be realized reading of radial error or record.
This clock gauge or pen recorder can be located at an end of driven axle, as drawing reference numeral 3d place, also can be directly the probe of clock gauge or pen recorder be contacted with the locator card arm of detent mechanism, because this locator card arm is fixedlyed connected with the driven axle axle sleeve, can measure the straight line displacement error situation of driven axle by the locator card arm.
Main drive shaft 1 can be by motor (with clothes motor, stepper motor etc.) driving or manual.
When the present invention uses, earlier a pair of tested gear pair is contained on main drive shaft 1 and the driven axle 2, main drive shaft 1 in main drive shaft axle bed 1a will by manually or motor-driven rotate, driven axle 2 is drive rotation during by tested gear pair engagement in driven axle axle bed 2a.
Main drive shaft axle bed 1a, driven axle axle bed 2a are fastened on the base 3 after aligning by locating distance, interaxial angle, and driven axle 2 can carry out a certain amount of rectilinear motion on a pair of accurate linear rolling track 2b simultaneously.
Detent mechanism 2c is fixed on the driven axle axle bed 2a, is used for when mounted driven axle 2 being fixed at tested gear pair.After tested gear pair Installation and Debugging are finished, open detent mechanism 2c, under the effect of the spring 2d that is provided with on the driven axle 2, tested gear pair promptly is in no sideshake engagement.This spring 2d can guarantee the no sideshake engagement of tested gear, and driven axle 2 can be moved axially on linear rolling track.
During detection, main drive shaft 1 drives microrunning through manual or motor etc., because tested gear pair turns round under no sideshake state, because the error of gear, the axially displaced of trace---the radial error of gear promptly appears in driven axle 2, by clock gauge or registering instrument record.
Spiral bevel gear, straight bevel gear generally are paired inspections, and straight bevel gear also can adopt and do not have the gap with master gear and mesh and detect radial error.
The present invention is by being provided with the no sideshake engagement that a pair of accurate linear rolling track, locating device, spring etc. have guaranteed tested gear on driven axle, driven axle can move by a spot of straight line simultaneously, and the diameter run-out that is together to form bevel gear detects key element.The present invention is simple in structure, and is reliable, and practicality is easy to operate, can improve the quality testing effect of bevel gear greatly.
