Description
Technical field
The present invention relates to round induction synchrometers, more particularly, to a kind of realization superhigh precision round induction synchrometer method.
Background technique
Round induction synchrometer is a kind of electromagnetic induction position detecting element, its feature be the influence to temperature it is insensitive,
Impact resistance, vibration, high pressure, vacuum, and can work continuously, while it protects the strong of pollutant certainly, such as oil, liquid, ash
Dirt, dirt, salt fog.Round induction synchrometer using high-accuracy delineation realize multipole induction winding, thus can reach high precision (±
1 "), while its matrix is metal material, has higher reliability compared to basis material for grating, the code-disc of glass.
The attainable full accuracy of round induction synchrometer is ± 1 ", the bottleneck of limits synchronization device precision is the number of poles of winding
It is limited.For round induction synchrometer winding groove form as shown in Figure 1, black portions are winding, blank parts are that groove processing needs
The part of removal.According to average effect, the number of poles of synchronizer winding is more, and attainable precision is higher.Currently, state's inner circle incudes
Synchronizer winding number of poles is up to 720 poles.
There are two types of the mode of winding groove is general, one kind is that machine adds groove, and this mode is to be placed on synchronizer assembly
On multiteeth indexing table, add groove with the milling machine machine of progress, which graduating accuracy is high, but general multiteeth indexing table is with the number of teeth
Increase, the diameter dimension of fluted disc becomes larger therewith.When the number of teeth is 1440, fluted disc diameter is about in 380mm or so, fluted disc at this time
Just it is able to satisfy the synchronizer groove process requirements of 720 poles.And the synchronizer of more multi-pole needs the more of more high angular resolution
Tooth circular dividing table, for multiteeth indexing table, high angular resolution makes the number of teeth excessive, causes multiteeth indexing table oversized, in this way
Difficulty is big in technique, and performance is unreliable.The oversized groove processing that also will affect synchronizer of multiteeth indexing table.By used more
The influence of tooth circular dividing table, groove number of poles are restricted (no more than 720 poles)；Another kind is corrosion groove, and this mode processes speed
Degree is fast, but graduating accuracy is influenced by groove template, and whole graduating accuracy is not high, and due to cost and plant issue, so that
The number of poles of groove template is few, and groove number of poles is caused to be restricted (no more than 720 poles).
Summary of the invention
The purpose of the present invention is to provide it is a kind of improve the accuracy class of round induction synchrometer, easy to operate, Yi Shixian, can
The realization superhigh precision round induction synchrometer method of strong operability, this method realize the prominent of winding number of poles by differential indexing technology
It is broken, achieve the purpose that synchronizer superhigh precision is realized.
