Description

Technical Field

[0001] This utility model relates to the field of code tape cleaning technology, specifically to a slip ring code tape self-cleaning device. Background Technology

[0002] The CT slip ring code tape serves to position the rotor rotation. The code tape is made of a steel strip with equally spaced small holes that wrap around the outer ring of the rotor. The gap between the small holes is usually about 1mm, allowing the optocoupler signal to pass through and provide rack position information. In order not to affect the rotor positioning, the dust on the slip ring code tape is removed by regular manual cleaning to prevent the small holes from being blocked.

[0003] Currently, cleaning the code tape requires disassembling the machine casing and using specific cleaning agents (such as alcohol) for regular cleaning, which increases maintenance costs. Utility Model Content

[0032] A rotating shaft 4 is sleeved on the inner side of the inner ring 12 of the bearing. One end of the rotating shaft 4 is connected to a fan 5. One end of the fan 5 is provided with a flow guiding mechanism 6. One end of the flow guiding mechanism 6 is provided with an air outlet 14. The air outlet 14 is located on one side of the code tape 8.

[0033] According to an embodiment of the present invention, a frame rotor is provided on one side of the frame stator 9. The frame rotor includes an inner ring 1 and an outer ring 7, and a code strip 8 is provided on the outside of the outer ring 7.

[0034] According to an embodiment of the present invention, a slide rail is provided on one side of the frame rotor near the inner ring 1 of the frame rotor, and a roller 2 is provided at one end of the rotating shaft 4, with the roller 2 disposed in the slide rail.

[0035] According to an embodiment of the present invention, an insulating material 13 is provided between the roller 2 and the slide rail.

[0036] According to an embodiment of this utility model, the flow guiding mechanism 6 is a cone-shaped body with a hollow interior.

[0037] According to an embodiment of the present invention, both ends of the cone are provided with openings, one of which is an air inlet and the other is an air outlet 14.

[0038] According to the embodiment of this utility model, both the air inlet and the air outlet 14 are circular structures, and the diameter of the air inlet is larger than the diameter of the air outlet 14.

[0039] According to an embodiment of the present invention, the flow guiding mechanism 6 is fixedly installed on the bracket 10.

[0040] Specifically, a bracket 10 is led out from the stator 9 of the frame (preferably the stator side brush / carbon brush plate), the bracket 10 fixes the outer ring 11 of the bearing, the inner ring 12 of the bearing passes through a rotating shaft 4, a roller 2 is nested on one side of the rotating shaft 4, and a fan 5 is nested on the other side of the rotating shaft 4. The fan 5 is wrapped with a tapered body with openings at both ends, and the tapered body is also connected through the bracket 10. The fan 5 is nested at the large opening end of the tapered body, and the small opening end points to the gap of the slip ring code tape 8.

[0041] The insulating material 13 between the roller 2 and the slide rail is in contact. The rotation of the slip ring drives the roller 2 to rotate. The rotation of the roller 2 drives the fan 5 to rotate through the shaft, generating wind power. The wind is blown out from the small opening of the cone to clean the dust in the gaps of the tape 8 in time.

[0042] In actual use, the diameter, blade shape, density, and cone size and shape of roller 2, shaft 4, and fan 5 can be adjusted.

It utilizes the rotation of the frame rotor to drive the fan 5 to blow away dust from the code tape 8 in a timely manner. Moreover, it is a purely mechanical mechanism that does not require external power supply. It can use the rotation of the frame rotor to drive the fan 5 and automatically blow the dust from the code tape 8 out of the rotor using a specific structure, without the need for external power.
