Abstract

The invention relates to a method and an apparatus for measuring small-modulus teeth, in particular for wave gear for use in large-scale industrial production. The aim of the invention is to organize a continuous quality assurance and to increase the Teileaauschbarkeit and the degree of functionality of the transmission. According to the invention, the object is achieved by a method with the assistance of a device which, in conjunction with concrete working steps, enables a high quality assurance.

Description

Explanation of the essence of the invention

The invention is based on the object, taking into account high accuracy requirements for wave gear to find such a measuring device, the function-oriented measurement of the Verzahnungspaßmaßes on the rigid wheel, including the geometric function-determining together hangs between installation base of the corrugated transmission and toothing axis, and with the mating teeth of the elastic wheel allows.

According to the invention, the object, as set forth in the claims 1-2, solved by two size-dependent spur gears whose axes are fixed in a common rotatable frame carrier. Both gear axes are rotatable, wherein an axis is additionally slidably arranged to transmit the diametric profile distance of the internal toothing as a maximum value by measurement on a display unit. The self-adjusting measurement of the diametric measure of the profile distances as a maximum value is achieved by the structural arrangement of a compression spring between the axes of both spur gears, with a floating support of the rigid wheel supports the automatic alignment of the teeth. In each angular position of the measuring device, the coincidence between the position of the mounting axis and the tooth axis is detected by a second transmitter, which indicates the difference between the reference base and the axis of the non-displaceable spur gear in addition to the diametric profile distance. The difference of the extreme display in one turn of the measuring device means the functionally effective runout of the wave gear.

The measuring device can be adjusted by final gauge, by a qualitatively determined rigid wheel, or by a measure taken from the pairing elastic wheel.

embodiment

The invention is illustrated and explained below with reference to an embodiment in a figure. According to the embodiment, the measuring device itself consists of a floating table 1, on which the associated components such as:

a rotatable and displaceable gear 3, a measuring gear 4, which is also formed detectable. Measuring transmitter 6 for detecting the diametrical profile distance, measuring sensor 7 for checking the concentricity deviations Arretiereinheit 8 for the non-rotatable mounting of the rigid wheel 2, a further locking unit 9, a drive 10 for the measuring device, and compression spring 11, which are summarized in their arrangement as a functional unit. In their function, the measuring device can be operated either by a feeder or by hand. In this case, the rigid wheel 2 is arranged on the floating table 1 so that it can be fixed in rotation by the lock 8 for functional testing. The preset measuring device 7 is now inserted into the rigid wheel 2 so that the height-adjustable frame carrier 5 can be used with the module-dependent Meßzahnrad 4 and located by clamping the locking unit 9 in the initial position Meßzanrad 3 in the rigid wheel 2. The previously actuated locking units 8; 9'will be solved. Due to the spring force of the pressure spring 11, the system is aligned diametrically. In any angle-related measuring position, the measuring device for the function axis reference (transmitter 7 for concentricity deviation) is preset. The measured value of the diametrical profile distance or the deviation from the preset reference value is taken over by the transmitter 6. By introducing a motor drive movement by drive 10, or if not designed by hand, the meter is rotated in defined angular increments by 360 °. After one revolution you will see visible:

- the variations of the diametrical test distance VM (display difference)

- The runout FV of the tooth axis with respect to the mounting axis by transmitter 7

In conjunction with downstream measuring devices, the so-tested component can be classified in the specified tolerance groups and classified by sorting devices known per se.

Invention claim: 1. A method for measuring internally toothed wheels, preferably of small modular design, mainly for wave gear through which a function oriented group interchangeability is enforced under the conditions of an automatic manufacturing process, characterized in that the internal gear (2) for determining the fitting dimension of the diametrical profile distance in a Rack support (5) is locked and in this state, module-dependent and mutually displaceable gears (3; 4) inserted diametral Prüfabstand bedend detected by a measuring device (6), then in defined rotational angle steps, a rotary motion is initiated by the after 180 ° comprehensive statement about the fluctuations of the Verzahnungspaßmaßes in the meter (6) are read and displayed in continuation of the rotational movement to 360 °, the functionally effective runout namely the mounting axis relative to the tooth axis by measuring device (7) and thus a comparison mi t the setpoint of the axis position is reached. 2. A device for carrying out the method, characterized by the arrangement of a, on a bogie (5) floating bearing (1) for receiving a rigid wheel (2) and the adhesion of the Meßzahnräder (3; 4) inducing spring (11), to the measuring gears (3; 4) encoder (6; 7) attack, one of these measuring gears is slidably disposed. For this 1 page drawing Field of application of the invention The invention relates to a method paired with a measuring device, in particular for small-module gears, especially for wave gear, through which a function-oriented group interchangeability under the conditions of an automated mass production is possible, so that by means of this measuring device a completely comprehensive control of all gear parts can be organized. Characteristic of known technical solutions With the WP G 01 B 2672135 a measuring and sorting device has already been proposed, are subjected to the small modal teeth, especially the elastic wheel for wave gear comprehensive production control and thus conditions of low-loss mass production are already created, so that only functional in the gearbox assembly Include parts that have been tested for proper running properties. But to achieve a further increase in quality even in large series and an absolute interchangeability, more measuring means are required to determine tooth pairings, which also allow accurate measurement and control of the teeth of the rigid wheel in corrugated gears, thus organized a balanced mass production and thus a created another control instrument through which error-free wheel pairings can be collected. This measuring device is used with a concurrent working method targeted for a funktiqnsorientierte control of the internal gear member, namely the rigid wheel, since according to the previously known prior art, the determination of the resulting Verzahnungspaßmaßes, such. the measurement of the diametrical two-ball measure M or where applicable, the application of this measurement method is complex and thus would not only cost-increasing effect, but also represents a significant disturbance factor in the final assembly. This circumstance has the consequence that, although the indirect reference to the functional axis of the internal gear wheel is possible in the investigations of the application of the metrological detection of the support surface Einkugelmaßes MR, but there is the disadvantage that the measurement must be pointwise, so that the measured value must be derived from the combined detection of the diameter of the mounting base and the indication value. This uncertainty leads to the fact that their application is refrained from, especially since an inclusion of this known measuring technique in the computer-aided quality assurance is not possible. Object of the invention The aim of the invention is to achieve a function-oriented group interchangeability of the corrugated transmission assemblies by the introduction of the same content measured variables and thereby to organize an economical production.
