Specific embodiment
The present invention is further described below combined with specific embodiments below.
As shown in Figure 1,2,3, 4, the present invention provides a kind of bevel gear tooth top hardness measurement bracket, is used for fixing bevel gear
In order to which the tooth top hardness to its gear measures, including flat bolster 2, oblique plate 3, cover board 4, housing screw 5, turning-over support
8, worm screw 12 and worm gear 13, wherein the end face of worm gear 13 is plane, and the two sides of oblique plate 3 are parallel with the end face of worm gear 13, is led to
Cross the connection that the mode that the end face of the side of oblique plate 3 and worm gear 13 welds together is realized to oblique plate Yu worm gear end face；It is flat
There is the groove of the wheel axle portion 16 of a receiving bevel gear 1 in 2 upper surface of backing plate, and design is so that bevel gear is placed on flat bolster 2 in this way
When, bevel gear 1 comes into full contact with flat bolster 2, and it is more firm, it is convenient for measuring, and cover board 4 cooperates, then pass through housing screw 5 for umbrella
Gear 1 is fixed on oblique plate 3, and the center line of oblique plate 3 is equipped with several threaded holes 17, and housing screw 5 is screwed in threaded hole,
So as to according to the size adjusting position of bevel gear 1, make the tooth top of bevel gear 1 be located at the delivery position of worm screw 12 and worm gear 13 just on
Side.
Grafting upset pin 14 in the worm wheel aperture of worm gear 13, turning-over support 8 are mounted on tray plate 7 by being coupled screw 9,
From the figure, it can be seen that there are two turning-over supports for setting altogether, the both ends of upset pin 14 are installed in rotation on two respectively and turn over
Turn in support.Worm screw 12 is installed in rotation in worm screw support 10, and worm screw support 10 is mounted on bracket by being coupled screw 11
On bottom plate 7.Worm screw 12 engages with worm gear 13, forms worm couple, drives worm gear 13 to rotate by rotary worm 12.This implementation
The worm screw 12 of example is realized by manual hand manipulation and is rotated, and also can use the drive of the driving devices such as motor.
14 clearance fit of turning-over support 8 and upset pin, enables upset pin 14 to rotate under the support of turning-over support 8, when
So clearance fit herein only describes turning-over support 8 and a kind of mutually matched mode of upset pin 14, it is any can be real
The mode that existing upset pin 14 is rotated relative to turning-over support 8 is all within the scope of the present invention.It the worm wheel aperture of worm gear 13 and turns over
It ships and resell on another market 14 interference fits, when worm gear 13 rotates, upset pin 14 and worm gear 13 are rotated together, and similarly, interference fit is also
A kind of fit system can also realize the rotation of worm gear 13 by other means.
As shown in Fig. 2, when in use, the inclination angle that manual rotary worm 12 adjusts oblique plate 3 and horizontal plane is first passed through,
It is allowed to mutually remaining with the tip angle of bevel gear 1, to ensure that the crest top land of bevel gear 1 is in a horizontal position, can be borrowed on oblique plate
Angle block gauge is helped to verify.Bevel gear 1 and flat bolster 2 are placed on oblique plate 3, it is ensured that the center of bevel gear 1 is in oblique plate 3
On heart line, and it measures tooth top and is located at right above 13 delivery position of worm screw 12 and worm gear, and upper cover plate 4 tightens housing screw 5；So
Entire bracket moves to hardometer test stand 6 flat greatly, cooperation hardometer tooth to bevel gear 1 fixed with C-shaped pincers 15 after capturing position afterwards
Top reply measures.
When specific implementation, the worm couple can be angular thread pair or trapezoidal thread pair.
The oblique inclination angle of plate 3 with respect to the horizontal plane can be surveyed in worm screw 12 and 13 delivery position setting angle encoder of worm gear
Amount correction can also install inclination sensor measurement correction at the back side of oblique plate 3.
Flat bolster 2, cover board 4 are using materials such as hard metals such as iron, stainless steel.
Schematically the invention and embodiments thereof are described above, description is not limiting, not
In the case where spirit or essential characteristics of the invention, the present invention can be realized in other specific forms.Institute in attached drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited to this, any attached drawing mark in claim
Note should not limit the claims involved.So not departing from this wound if those of ordinary skill in the art are inspired by it
In the case where making objective, frame mode similar with the technical solution and embodiment are not inventively designed, should belong to
The protection scope of this patent.
