Description
Technical field
The present invention relates to a kind of internal spline stick gap measuring devices, can be widely applied to gear inner spline stick distance measurement mistake
Cheng Zhong.
Background technique
Internal spline stick spacing be examine internal spline size whether qualified predominantly detect one of means, currently, gear industry
Internal spline stick spacing is generally measured using length bar with internal caliber gauge without special measuring device.Specific measurement method is:
The coating butter on the face of length bar and tooth socket face, and the internal spline tooth socket flank of tooth is tangent contacts, and butter plays the work of stick
With then with the distance between two length bar of calliper to measure.Measure, have the following problems in this way: first is that, length bar and the tooth socket flank of tooth it
Between add butter thickness number, directly affect measurement result；Second is that it is unreliable to position, directly because two length bars bonding is insecure
Influence measurement result；Third is that there are measurement accuracy and the collimation errors because of slide calliper rule own structural characteristics, numerical value inaccuracy is measured, especially
It is that strong fix is unable to due to two length bars, and operator exerts oneself difference, and measurement result can be made because exerting oneself, and different there are biggish differences
Different, measurement accuracy is affected by human factors larger, and measurement efficiency is low.
Summary of the invention
The purpose of the present invention is to provide a kind of measurement it is convenient with quick, length bar positioning is reliable, measurement is accurate, structure letter
Single, easily manufactured, applied widely, convenient disassembly, the easy internal spline stick gap measuring device of maintenance.
In order to achieve the above object, internal spline stick gap measuring device of the present invention, including be inserted into gear internal splined hole, be equipped with
Bellmouth, with end face positioning table and end face positioning table sets internal thread internal expansion type ringfeder, be located at gear inner spline hole with
Between internal expansion type ringfeder lateral surface, on internal spline circumference with respect to installation and two length bars tangent with the internal spline tooth socket flank of tooth,
Top has driving hole, lower part has external screw thread, is mounted in internal expansion type ringfeder, is threadedly coupled with internal expansion type ringfeder and with taper
Expander, the ranging micrometer caliper being clamped between two length bars.
Internal spline stick gap measuring device of the present invention, it is described on internal spline circumference with respect to installation two length bars, it is interior
When spline even number tooth, two length bars are in two tooth sockets in 180 degree angle, and two length bars are in full symmetric state at this time.
Internal spline stick gap measuring device of the present invention, it is described on internal spline circumference with respect to installation two length bars, it is interior
When spline odd number gear, a length bar is first installed in tooth socket, then closing in tooth socket in the 180 degree angle of the tooth socket is installed
Another length bar, two length bars are in non complete symmetry state at this time.
Internal spline stick gap measuring device of the present invention, the expander top driving hole are hexagonal inside groove.
Internal spline stick gap measuring device of the present invention, the expander top driving hole, the expander inside groove can be
It is hexagonal, it can also be other forms, can facilitate and be tightened in wrench insertion groove, unclamp expander.
Internal spline stick gap measuring device of the present invention takes internal expansion type ringfeder and gear inner spline hole contact tensioner side
Formula.
Internal spline stick gap measuring device of the present invention, the course of work is: expander and internal expansion type ringfeder taper fit, length bar
It is tangent with the internal spline tooth socket flank of tooth.When measuring internal spline stick spacing, internal expansion type ringfeder is put into gear inner spline hole and passes through work
Part end face and end face positioning table position, and two length bars of opposite insertion in inner spline gear slot, length bar surface does not need coating butter.
Spanner is inserted into the driving hole of expander top, is screwed down expander with wrench, by being threadedly engaged, is positioned into internal expansion type ringfeder
In the internal screw thread of platform.Because expander and internal expansion type ringfeder are taper fits, when expander moves down, internal expansion type ringfeder spreading, from
And make length bar and the tangent close contact of the tooth socket flank of tooth, then distance value on the outside of two length bars is measured with micrometer caliper.Outside two length bars
Lateral extent value subtracts 2 times of Pins diameter, is exactly internal spline stick pitch measurements.After having measured, is unclamped and risen upwards with wrench
Tire, to unclamp internal expansion type ringfeder, length bar and the tooth socket flank of tooth unclamp, and extract length bar out, can take out product.Therefore, measurement is convenient
With it is quick.
Internal spline stick gap measuring device of the present invention, the internal expansion type ringfeder and expander, expander penetrate internal expansion type ringfeder
In, together, internal expansion type ringfeder is motionless, rotating spanner for two cone match of equal angular, expander by internal expansion type ringfeder with
Being threadedly engaged between expander moves down, and two conical surfaces press together, and internal expansion type ringfeder swells, to fix in gear
Spline and length bar.
Internal spline stick gap measuring device of the present invention, the positioning to two length bars, using expander and internal expansion type ringfeder taper
Cooperate location structure, internal expansion type ringfeder tensioner length bar is in close contact length bar and internal spline tooth socket, and therefore, length bar positioning is reliable.
Internal spline stick gap measuring device of the present invention, first is that, since length bar positioning is reliable, measurement process is not used by operator
The influence of power size, therefore, measurement are accurate；Second is that length bar surface does not need coating butter, length bar surface coating butter is avoided
Caused measurement error；Third is that measurement numerical value is accurate, and parallax reading error is small using micrometer caliper.Therefore, the present invention can be accurate
The stick distance values for measuring internal spline, measurement is accurate, avoids traditional technology length bar coating butter and length bar and tooth socket tooth
Face is bonded insecure caused measurement error.
Internal spline stick gap measuring device of the present invention, structure is simple, easily manufactured, applied widely, can measure any shape
The internal spline stick spacing of formula product.
Internal spline stick gap measuring device of the present invention, using the expander structure of internal expansion type ringfeder and strap wrenches hole, disassembly side
Just, maintenance is easy.
In conclusion internal spline stick gap measuring device of the present invention, measurement is convenient with fast, and length bar positioning is reliable, measurement
Accurately, structure is simple, easily manufactured, applied widely, convenient disassembly, and maintenance is easy.
