Abstract
It is a kind of with the code-disc fixed structure for preventing motor bearings discharging function over the ground, including pedestal, brush holder mechanism, pedestal is tool there are two the structure with crown of roll disk, and center is through-hole；In two convex disks, the convex disk of pedestal one end is code-disc fixing axle mounting base, and the other end of pedestal is code-disc installation position；The convex dish external diameter of the middle of the base is that carbon brush and code disk shaft contact position, and two convex disks have standing screw through-hole；Brush holder mechanism includes the brush holder fixed link for being fixed on the non-load side of motor, the grounding carbon brush frame for being fixed on brush holder fixed link, and grounding carbon brush is connected with carbon brush with code-disc by contacting position.Its advantage is that having the function of the function that original drive code-disc inner ring of code-disc fixing axle is rotated and effectively combined with grounding carbon brush；The function that grounding carbon brush can effectively be played, prevents shaft current from discharging over the ground through shaft bearing, damages bearing；Grounding function is combined with code-disc s function, achievees the effect that dual-use material；Design scheme structure is simple, at low cost.
Description
Technical field
The utility model relates to motor technology fields, in particular to one kind, which has, prevents motor bearings discharging function over the ground
Code-disc firm banking.
Background technique
Motor can be generated between uneven, higher harmonic components and shaft because of magnetic circuit in the process of running electromagnetic induction,
The reasons such as static charge accumulation generate shaft voltage and shaft current.When shaft current is discharged through shaft bearing, because contact area is smaller, putting
Electric moment generates high temperature, can make bearing Local Damaged, endangers equipment big.In general, 600kw or more direct current generator can be in motor
Front axle installs a brush carrier, and the generation of shaft voltage and shaft current is avoided by grounding carbon brush electric discharge.Direct current below for 600KW
Motor, producer's then less prepackage grounding carbon brush brush carrier.The motor of grounding carbon brush brush carrier is not installed, front axle is shorter, is pacifying when factory
Remaining space after installing motor catcher is not enough to install grounding carbon brush brush carrier.Electric motor back shaft is code-disc installation position, and code disk shaft is not
It can be contacted very well with grounding carbon brush, not have the effect that ground connection eliminates charge.
Utility model content
The purpose of this utility model be just to provide it is a kind of guarantee code disk shaft normal function under the premise of installation for preventing
The code-disc fixing axle scheme for the grounding carbon brush that motor bearings discharges over the ground, it is intended to solve rear-loading type grounding carbon brush be not easy to installation ask
Topic has the code-disc fixed structure for preventing motor bearings discharging function over the ground.
The solution of the utility model is such that
It is a kind of with the code-disc fixed structure for preventing motor bearings discharging function over the ground, including pedestal, brush holder mechanism, it is described
Pedestal is that there are two the structures with crown of roll disk for tool, and center is through-hole, so that pedestal is socketed on code-disc fixing axle using through-hole；
In two convex disks, the convex disk of pedestal one end is code-disc fixing axle mounting base, and the other end of pedestal is code-disc installation position；The middle of the base
Convex dish external diameter be that carbon brush and code disk shaft contact position, two convex disks have standing screw through-hole；The brush holder mechanism packet
Include the brush holder fixed link for being fixed on the non-load side of motor, the grounding carbon brush frame for being fixed on brush holder fixed link, the grounding carbon brush frame
To be equipped with grounding carbon brush outside every side overhanging arm, grounding carbon brush is with carbon brush and code-disc by contacting position phase to two sides overhanging arm
It connects.
The utility model has the advantages that have the function of code-disc fixing axle original drive code-disc inner ring rotation and with
The function that grounding carbon brush effectively combines；The fixed shaft body of the code-disc is easily installed, the grounding carbon brush brush carrier no-float with rear dress；
The function that grounding carbon brush can effectively be played, prevents shaft current from discharging over the ground through shaft bearing, damages bearing；By grounding function with
Code-disc s function combines, and achievees the effect that dual-use material；Design scheme structure is simple, at low cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model pedestal.
Fig. 2 is the utility model mounting structure schematic diagram.
Fig. 3 is the stereoscopic schematic diagram of the utility model mounting structure.
Figure elements detail are as follows: code-disc fixing axle mounting base 1, carbon brush and code disk shaft contact position 2, are fixed code-disc installation position 3
Screw through hole 4, brush holder fixed link 5, grounding carbon brush 6, grounding carbon brush frame 7, carbon brush and code-disc contact position 8, code-disc fixing axle 9, electricity
The non-load side 10 of machine, encoder 11.
Specific embodiment
As shown in Figure 1, 2, the utility model includes pedestal, brush holder mechanism, and the pedestal is that there are two the same as crown of roll disk for tool
Structure, center is through-hole, so that pedestal is socketed on code-disc fixing axle 9 using through-hole；In two convex disks, pedestal one end it is convex
Disk is code-disc fixing axle mounting base 1, and the other end of pedestal is code-disc installation position 3；The convex dish external diameter of the middle of the base is carbon brush and code
Dish axle contacts position 2, and two convex disks have standing screw through-hole 4；The brush holder mechanism includes being fixed on the non-load of motor
The brush holder fixed link 5 at end 10, the grounding carbon brush frame 7 for being fixed on brush holder fixed link 5, the grounding carbon brush frame 7 are overhanging to two sides
Arm, is equipped with grounding carbon brush 6 outside every side overhanging arm, and grounding carbon brush 6 is connected with carbon brush with code-disc by contacting position 2.
It, need to be in the non-load side 10 of motor when being transformed using the utility model to the motor for not installing grounding carbon brush brush carrier
Fixed brush holder fixed link 5, so that grounding carbon brush frame 7 is connected to brush holder fixed link 5；The central through hole of pedestal is socketed on code-disc
Fixing axle 9 simultaneously by the assembly of code-disc fixing axle mounting base 1 in place, at this point, be installed on the grounding carbon brush 6 of grounding carbon brush frame 7 just with
Carbon brush connects with code disk shaft contact position 2, and encoder 11 is installed at code-disc installation position 3, that is, is assembled to form the utility model.
