Embodiment Construction

[0023] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0024] Such as Figure 1-4 As shown, the gear assembly includes a gear seat 2 and a rotatable gear 4 arranged on the gear seat 2. There is also an annular circuit board fixed on the gear seat 2 and sensing the rotation angle of the gear 4 between the gear 4 and the gear seat 2. 6. The gear 4 is provided with a magnet 46 , and the annular circuit board 6 is provided with a plurality of Hall elements 66 for sensing the magnet 46 .

[0025] The gear seat 2 includes a plate-shaped base 22 and a side wall 24 vertically arranged on the edge of the base 22 . Wherein the middle part of base 22 is provided with the shaft hole 222 that gear 4 is inst...

Abstract

The invention relates to a gear component, comprising a gear seat and a gear ratably arranged on the gear seat; an annular circuit board which is fixed on the gear seat and is used for sensing the rotation angle of the gear is also arranged between the gear and the gear seat; a magnet is arranged on the gear; hall elements for sensing the magnet are arranged on the annular circuit board. According to the gear component, disclosed by the invention, the position of the magnet is sensed by the hall elements by means of the specially-designed annular circuit board structure, as so to determine the rotation angle of the gear, the structure is simple, and the sensing is accurate and effective. Particularly, multiple hall elements distributed in the circumferential distribution can be arranged on the annular circuit board, the multiple different rotation angles and positions of the gear can be sensed, and different requirements are met. For instance, when the gear is connected with a valve rod of a valve and controls the valve rod to perform reciprocating motion, the position change of the gear can control the displacement of the valve rod, and the regulation of the valve is realized.

Description

technical field [0001] The invention relates to a gear assembly. Background technique [0002] Gears are wheel-shaped mechanical parts that transmit torque by the meshing of teeth, and are widely used in various transmission structures. With the development of technology, people need to know and control the rotation angle of the gear, so as to precisely control the movement of the parts connected with the gear, so as to achieve the purpose of automation. However, the existing sensing element has a complicated structure and a large volume, and it is not convenient to be installed in a corresponding gear seat with the gear to accurately sense the rotation of the gear. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides a gear assembly with simple structure, space saving, accurate induction and convenient assembly. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: ...
