Problems solved by technology

[0011] In general, the two methods have a serious disadvantage in accuracy, namely: the corrosion method is easy to damage the tooth surface accuracy of the measuring tooth, or the tooth surface of the measuring tooth glued out by the pasting method is not high in accuracy
The accuracy of the measuring tooth itself is not high enough, which is intolerable as a measur

Embodiment Construction

[0027] The manufacturing method of the present invention is to use a multi-lead hob (or worm grinding wheel) with a thicker tooth thickness value to process conventional, tiny (usually gear modulus less than 0.4mm), non-skipping measuring gears into tiny Jump tooth measurement gear.

[0028] Manufacturing of tiny non-skipping measuring gears

[0029] Measuring gears without jumping teeth, which is commonly referred to as measuring gears. The dimensions of each individual pitch are equal, and the width dimensions of each tooth groove are also equal, such as figure 1 . In the figure, if the inter-tooth pitch between No. 1 tooth and No. 2 tooth is P12, and so on, there are:

[0030] P12=P23=P34=P45=P56

[0031] Its manufacturing method is to process with a high-precision hob (or grinding wheel) of conventional geometry, such as figure 2 . At this time, the tooth shape of the non-skipping measuring gear and the tooth shape of the hob are consistent with the tooth shape of t...

Abstract

The invention discloses a method for manufacturing a micro nth skipping-thread measuring gear, which solves the problems that the conventional method for manufacturing the skipping-thread measuring gear has complex process, low production efficiency and low product precision. In the measuring gear, n toothed grooves are added every other normal toothed groove, wherein n is a natural number. The method for manufacturing the micro nth skipping-thread measuring gear adopts a generating cutting method or a gear grinding method to process, and comprises the following steps that: (1) micro skipping-free measuring gears with the same toothed groove width processed by a general skipping-free hob or grinding wheel of which the normal lead value is pi m are used as blanks, wherein the m is gear modulus and is less than 0.4 millimeter, and the tooth pitch and tooth shape of two adjacent teeth of the blank are equal to or accordant with those of a standard rack of a basic worm of the hob or the grinding wheel; and (2) the widened tooth grooves of the micro skipping-thread measuring gear are processed by a hob or a grinding wheel of which the normal lead value is (n+1) pi m and the tooth thickness is equal to the sum of the tooth thickness of the skipping-free hob or grinding wheel and 2delta, wherein the delta is the widened amount of the single-side tooth surface of the skipping-thread widened toothed groove.

Description

Technical field: [0001] The invention relates to a machining method for measuring gears. Background technique: [0002] Gear accuracy detection methods are classified according to the form of measuring components, which can be divided into: probe-type gear measuring instrument, gear-type gear measuring instrument and worm-type gear measuring instrument. [0003] The single geometric error measurement of the gear is based on the point probe as the measuring element; the comprehensive error measurement of the gear is measured by measuring the gear without jumping teeth (that is, a high-precision normal gear) or measuring the worm without jumping teeth (that is, a high-precision normal worm). Components; The overall error measurement of the gear is to use the jumping tooth measuring gear (or the jumping tooth measuring worm) as the measuring element. [0004] Measuring gears can be divided into measuring gears without jumping teeth and measuring gears with jumping teeth. The ...
