Abstract
The utility model relates to a paraxial synchronous rotation structure which comprises an encoder, a connecting block, a first connecting rod, a second connecting rod, a swing arm and a rotating shaft. The encoder is hinged to the connecting block, and a first rotation point is formed in the hinged position of the encoder and the connecting block; the connecting block is fixedly connected with one end of the first connecting rod, the other end of the first connecting rod is hinged to one end of the second connecting rod, and a second rotation point is formed in the hinged position of the first and second connecting rods; the other end of the second connecting rod is hinged to the swing arm, a third rotation point is formed in the hinged position of the second connecting rod and the swing arm, and the swing arm is fixed on the rotating shaft; and the first rotation point, the second rotation point, the third rotation point and the center of the rotating shaft are distributed in a parallelogram. According to the utility model, when the encoder cannot be connected with the coaxial central of the rotating shaft, the first and second connecting rods and the connecting block are used to realize rigid connection with the swing arm, thereby overcoming limit of structural space during measurement, decreasing measurement errors, and improving measurement precision; and thus, the structure has wide application prospects.
Description
Technical field
The utility model relates to a kind of paraxonic synchronous rotary structure.
Background technology
Currently available technology, for the rotational angle of rotation axis or the measurement of the rotation number of turns, is generally used shaft coupling that scrambler is connected with one end concentric of rotation axis.Yet for the restriction in structure or space, scrambler cannot be connected with rotation axis concentric sometimes; To this, classic method is to adopt Timing Belt or chain by scrambler connection parallel with rotation axis., there is certain driving error (this error is caused by " flexibility " and " gap " of Timing Belt or chain) in band chain transmission.For the measurement of rotating the number of turns, this error is negligible; But for the measurement of less rotational angle, this error is very important.
Summary of the invention
In order to solve above-mentioned technical matters, the purpose of this utility model is to provide a kind of paraxonic synchronous rotary structure of indirect measurement of the anglec of rotation that is applicable to axle, and this structure is rigid connection structure, effectively the error of controlled encoder measurement result.
In order to realize above-mentioned object, the utility model has adopted following technical scheme:
A synchronous rotary structure, comprises scrambler, contiguous block, first connecting rod, second connecting rod, swing arm and rotating shaft; Described scrambler and contiguous block are hinged, and hinged place forms the first run-on point; Contiguous block is fixedly connected with one end of first connecting rod, and the other end of first connecting rod and one end of second connecting rod are hinged, and hinged place forms the second run-on point; The other end and the swing arm of second connecting rod are hinged, and hinged place forms the 3rd run-on point, and swing arm is fixed in rotating shaft; Described the first run-on point, the second run-on point, the 3rd run-on point become parallelogram to distribute with spindle central.
As preferred version: described scrambler is fixed on pedestal by support.By support, fix, make the choice of fixed position of scrambler larger, be applicable to the occasions that are subject to structure or space constraint more.
As preferred version: described first connecting rod and second connecting rod are the stiff rod that rigid material is made.Rigid material effectively reduces the error that scrambler is measured.
The utility model is owing to having adopted above-mentioned technical scheme, cannot be when " rotating shaft " concentric be connected at scrambler, use first connecting rod, second connecting rod, contiguous block realization to be rigidly connected with swing arm, when overcoming the restriction of structure space while measuring, also reduced the error of measuring, strengthened measuring accuracy, be with a wide range of applications.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made a detailed explanation.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of paraxonic synchronous rotary structure, comprises scrambler 1, contiguous block 2, first connecting rod 3, second connecting rod 4, swing arm 5 and rotating shaft 10; Described scrambler 1 is hinged with contiguous block 2, and hinged place forms the first run-on point 6; Contiguous block 2 is fixedly connected with one end of first connecting rod 3, and one end of the other end of first connecting rod 3 and second connecting rod 4 is hinged, and hinged place forms the second run-on point 7; The other end of second connecting rod 4 and swing arm 5 are hinged, and hinged place forms the 3rd run-on point 8, and swing arm 5 is fixed in rotating shaft 10; Described the first run-on point 6, the second run-on point 7,9 one-tenth parallelogram of the 3rd run-on point 8 and spindle central distribute.Described scrambler 1 is fixed on pedestal 11 by support 12.Described first connecting rod 3 is with second connecting rod 4 stiff rod that rigid material is made.
This paraxonic synchronous rotary structure, is applicable to the indirect measurement of the anglec of rotation of axle, and taking measurement of an angle should be within ± 90 ° of scope.This structure is rigid connection structure, effectively the error of controlled encoder measurement result.
