Abstract

Multi-parameter gear measuring device consists of a radius scale (1), centering bar (2), pin with angular gauge (3) on which it is left arm (4) with left gauge (5) and right shoulder (6) with right gauge (7).

Description

Area, techniques

The multi-parameter gear measurement device is designed to measure engagement angle, involute-shape, gear-to-tooth, and tooth-to-tooth variations across a wide range of modules and number of teeth. It is particularly suitable for measuring large gears over 500 mm in diameter and as an attachment to production machines.

BACKGROUND OF THE INVENTION

Prior art devices for measuring tooth flank profiles generally consist of a basic ruler having an adjustable roller on one side and a pivot with an angular measuring member to which a radius ruler is connected with an adjustable linear measuring member on the other.

The multi-parameter gear measurement device differs from the gear side profile measuring device in that it has a deflector arm, radius scale and centering bar instead of a basic ruler with a roller. This results in a higher effect, since the multi-parameter gear measuring device makes it possible to measure the left and right tooth flanks simultaneously.

SUMMARY OF THE INVENTION

The principle of the invention is based on the fact that the device for multi-parameter measurement of gears consists of radius scale, centering bar, pin with angle gauge, on which the left arm with the left deflector and the right arm with the right deflector are located. coordinate system linked to the axis of rotation of the gear to the coordinate system formed on the tangent to the base circle of the gear, in which measurement is made in polar coordinates

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows the geometric principle of measurement, and FIG. 2 shows a specific embodiment of a multi-parameter gear measurement device.

An example of an embodiment of the invention

The device for multi-parameter measurement of gears consists of the radius scale JL, the centering bar 2, the pin with the angle gauge 3, on which the left arm 4 with the left deflector 5 and the right arm 6 with the right deflector 7 are located.

The angle gauge pin 3 is set to the basic circle of the gear by means of the radius scale i and the centering bar 2 to the position to which it applies

The multi-parameter measurement of the gear takes place by turning the left leg 4 and the right leg 6 around the center S of the angle gauge pin 3 to detect the deviations of the actual tooth profile distances r (φ) from the circle with the set radii r _p ar _L , where in _p (<p) = r (φ) -r ν _£ (φ) = r (φ) -r φ ^- is the angle of rotation measured on the pin with angular scale ν _ρ (φ) - are deviations of the circle with the radius r set from the required tooth profile

Vj / φ) - are deviations of circle with set radius r from required tooth profile

From the measured deviations ν (φ) not shown in the example, the deviations of the angle of engagement, deviations of the involute shape, the deviations of the measure across the teeth and the deviations of the gear teeth.

In particular, a higher angle effect occurs when the angle gauge pin 3, the left-hand dial 5 and the right-hand dial 2 cooperate with the computer where the calculations for the measurement evaluation are programmed.

Industrial usability

The multi-parameter gear measuring device according to the invention is used in the production of gearboxes and everywhere there. where the precision, the production of gears.

there is a need to control
