Abstract
The erecting device that the utility model discloses a kind of hollow encoder, is characterized in that, comprises axle, brace and support, and described support is provided with groove near a side of hollow encoder; Hollow encoder is by tensioning screw fixed cover on axle, and described brace is positioned at hollow encoder one side, is close in groove.The utility model, according to mill produced on-site situation, by repeatedly optimizing, finally provides a kind of mounting structure of hollow encoder, avoids, because connectivity problem causes encoder feedback abnormal, reducing the impact on produced on-site.
Description
Technical field
The utility model belongs to the mounting technique field of motor encoder, is specifically related to a kind of erecting device of hollow encoder.
Background technology
Growing along with motor frequency conversion technology, variable-frequency motor is applied in every field more and more widely, variable-frequency motor is higher for the control requirement of motor speed, need to measure accurately and feed back for the rotating speed of motor, generally will rotary encoder be installed on the main shaft of motor the rotating speed of motor is measured and controlled.
In prior art, due to solid encoder in use encoder bearing and shaft coupling damage frequency higher, so adopt the lower hollow encoder of failure rate.Hollow encoder is enclosed within on axle, and is fixed on support with Ф 4 screws, and support is fixed on motor; in actual motion; often can there is fixed screw fracture (nut is not tightened) or brace fracture (nut screwing clamping), cause encoder feedback data to make mistakes, cause heap steel accident.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model is according to mill produced on-site situation, by repeatedly optimizing, a kind of mounting structure of hollow encoder is finally provided, avoid, because connectivity problem causes encoder feedback abnormal, reducing the impact on produced on-site.
The problem existing for solving above-mentioned prior art, the technical scheme that the utility model is taked is: a kind of erecting device of hollow encoder, it is characterized in that, comprise axle, brace and support, described support is provided with groove near a side of hollow encoder; Hollow encoder is by tensioning screw fixed cover on axle, and described brace is positioned at hollow encoder one side, is close in groove.
Described recess width is consistent with brace width, realizes the two and fits tightly fixing.
Described backing thickness is 8mm.
The groove of described support is rectangle.
The two ends, edge that described support is relative with groove are provided with through hole.By this through hole, can use Ф 10 screws and motor to fix.
Described tensioning screw is Ф 4 screws.
Described tightening bolt is uniformly distributed along hollow encoder.
Described tightening bolt is 3 or 4.
The erecting device of hollow encoder described in the utility model, encoder installation method is simple, support in use can not affect the normal work of motor, and employing groove design, brace is close to after groove, at encoder, follows bearing while rotating, and brace can skew place groove, meanwhile, also can because of fixed screw, not rupture (nut is not tightened) or brace fracture (nut screwing clamping) causes encoder to test the speed to make mistakes.After encoder is installed, according to on-the-spot operating statistic, improved over the past two years, without the fault of mistaking because of the encoder reason scene of causing.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of structure described in the utility model;
Wherein: 1 hollow encoder, 2 axles, 3 braces, 4 supports, 5 grooves, 6 tensioning screws, 7 through holes.
Embodiment
Below in conjunction with embodiment, the utility model is elaborated.
Embodiment 1
The erecting device of a kind of hollow encoder 1 as shown in Figure 1, comprises axle 2, brace 3 and support 4, and described support 4 is provided with groove 5 near a side of hollow encoder 1; Hollow encoder 1 is by tensioning screw 6 fixed covers on axle 2, and described brace 3 is positioned at hollow encoder 1 one sides, is close in groove 5.Groove 5 width are consistent with brace 3 width, realize the two and fit tightly fixing.Support 4 thickness are 8mm.The groove 5 of support 4 is rectangle.The two ends, edge that support 4 is relative with groove 5 are provided with through hole 7.By this through hole 7, can use Ф 10 screws and motor to fix.Tensioning screw 6 is Ф 4 screws.Tightening bolt 6 is uniformly distributed along hollow encoder 1.Tightening bolt 6 is 3.
Embodiment 2
Embodiment 2 is that with the difference of embodiment 1 tightening bolt is 4.
