Description

Technical Field

[0001] The utility model relates to the technical field of gear sensor devices, in particular to a magnetic induction speed measuring gear disc. Background Art

[0002] A gear sensor typically consists of a magnet and a magnetic sensor (such as a Hall effect element). The magnet is attached to the gear. When the gear moves, the magnet moves with it. The magnetic sensor senses the change in the magnetic field and generates a corresponding electrical signal. Based on the change in the signal, the speed and position of the gear can be determined.

[0003] When installing the existing speed measuring sprocket, screws are generally inserted into the small holes on the corners of the speed measuring sprocket shell to completely fix it. At this time, when in use, some installation positions have fixed installation holes, but there are situations where the small holes on the corners of the speed measuring sprocket shell do not correspond to the positions of the installation holes, which is not conducive to installation and requires re-drilling.

[0004] Therefore, a magnetic induction speed measuring gear disc is provided to solve the above-mentioned problems. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1:

[0026] Reference Figure 1-4 , a magnetic induction speed measuring gear disc, including a mounting base 1, a device chamber 101 is provided on the mounting base 1, a gear 102 with a magnet is rotatably connected in the device chamber 101, and a magnetic sensitive sensor 103 for detecting the rotation speed of the gear 102 with a magnet is connected to the device chamber 101, and further comprising: two sets of air openings 201, respectively provided at opposite ends of the mounting base 1; air openings 203, provided at opposite ends of the mounting base 1, the air openings 203 being communicated with the air openings 1 201; a mounting nose 3, slidably connected in the air opening 1 201; a nut 403, slidably connected in the air opening 1 201; a locking bolt 401, slidably connected in the air opening 203, the head of the locking bolt 401 being larger than the air opening 203, and the locking The tightening bolt 401 passes through the mounting nose 3, and the through end is threadedly connected to the nut 403. By rotating the locking bolt 401, the nut 403 can be pressed against the mounting nose 3. Grooves 202 are provided at the opposite ends of the mounting seat 1. The groove 202 is communicated with the empty port 1 201. A sliding plate 402 matching the size of the groove 202 is slidably connected in the groove 202. The nut 403 is fixedly connected to the sliding plate 402. The locking bolt 401 passes through the sliding plate 402. A rubber plate 404 is fixedly connected to the sliding plate 402. The rubber plate 404 is used to press against the mounting nose 3. The mounting nose 3 is provided with a mounting hole 301 and a limiting opening 302. The locking bolt 401 passes through the limiting opening 302.

[0027] When the device is in use, by pulling the mounting nose 3, the mounting nose 3 can be pulled arbitrarily within a range of 180 degrees, and then the position of the mounting hole 301 on the mounting nose 3 is adjusted so that the position of the mounting hole 301 is aligned with the eyelet on the mounting position, and then the screw can be inserted to fix it. At this time, the screw is not tightened. The other three groups are similar. After they are all inserted, the gear 102 with the magnet can be connected to the rotating end. Alternatively, the gear 102 with the magnet can be connected to the rotating end first, and then the positions of the four mounting holes 301 are fixed. After the rotating end is connected, the locking bolts 401 can be rotated one by one, preferably tightened diagonally.

[0028] When the locking bolt 401 is rotated, the second opening 203 restricts the mounting bolt 401, and the rotation of the bolt 401 drives the nut 403 to continuously approach the mounting nose 3, thereby causing the rubber plate 404 to move away from the mounting nose 3 and then continuously approach the mounting nose 3, thereby clamping and fixing the mounting nose 3.

[0029] After fixing the locking bolt 401, the screw in the mounting hole 301 can be tightened and fixed. At this time, the installation of the induction speed measuring gear is completed. Finally, the magnetic sensor 103 is connected to an external computer or other control system to facilitate the detection of the equipment's speed.

[0030] After use, the mounting base 1 can be removed by rotating the screw 205 and the locking bolt 401 in the opposite direction and releasing the connection between the gear and the rotating end. After removal, the mounting nose 3 can be put into the opening 201, and can be inserted vertically or tilted, or the edge line of the longer end of the mounting nose 3 can be kept parallel to the edge line of the mounting base 1, and finally locked and fixed by the locking bolt 401.

[0031] Example 2:

[0032] Reference Figure 3 , a magnetic induction speed measuring gear disc, which is basically the same as Example 1, furthermore: an inspection plate 204 is provided on the mounting seat 1, and a screw 205 is connected to the inspection plate 204. By opening the inspection plate 204, the sliding plate 402, the nut 403 and the rubber plate 404 can be removed from the groove 202.

[0033] Through the setting of the inspection plate 204, when it is necessary to add, reduce or replace the mounting nose 3 in the future, it is only necessary to open the inspection plate 204, and then the inspection plate 204, the nut 403 and the rubber plate 404 can be taken out from the groove 202, or the inspection plate 204, the nut 403 and the rubber plate 404 can be added, and the number of mounting holes 301 can be increased by adding mounting noses 3 and locking bolts 401, and finally, it is only necessary to cover the inspection plate 204 again.

[0034] The mounting hole 301 of the utility model can be adjusted arbitrarily in position and angle, and can be applied to most situations when in use without the need for re-drilling. When not in use, the mounting nose 3 can be stored in the empty opening 201 to reduce damage and facilitate the installation of the magnetic induction speed measuring sprocket.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
