Detailed Description
Referring to fig. 1 and 2, the present invention provides a position detecting device based on a planetary gear mechanism, which comprises a housing, a position switch 7 disposed in the housing, an input shaft 1 limited on the housing, and a planetary gear assembly. The input shaft 1 may be a shaft connected with a motor at the driving end of a mating device, and may be a rotating shaft of the measured equipment (such as a rotating shaft of a roller in a belt conveyor).
The housing described above comprises a front shell 11 and a rear shell 12. The front shell 11 and the rear shell 12 are connected through connecting bolts to form a cavity for mounting each component.
The planetary gear assembly comprises a mounting frame 2 arranged in a shell, a driving gear 3 fixed on an input shaft 1, a gear ring 4 limited in the mounting frame 2, a planetary gear 5 meshed with the internal teeth of the driving gear 3 and the gear ring 4 respectively, and a rotating plate 6 used for mounting the planetary gear 5, wherein a boss 6-1 for triggering a position switch 7 to act is arranged on the rotating plate 6. In the scheme, the gear ring 4 is fixed, the driving gear 3 on the input shaft 1 rotates to drive the planetary gear 5 to rotate around the planetary gear, and further the rotating plate 6 is driven to rotate, so that the boss 6-1 on the rotating plate is contacted with the position switch 7 to trigger corresponding actions of equipment.
The planetary gear 5 is rotatably held on the rotating plate 6 by a holding shaft 8. The installation frame 2, each gear, the limiting shaft and the rotating plate 6 are made of polyformaldehyde, and friction force in the movement process is reduced by utilizing the self-lubricating characteristic of the polyformaldehyde.
When the input shaft 1 rotates for a certain number of turns, the planet gear 5 drives the rotating plate 6 to rotate for a circle, and then the position switch 7 is triggered once. Since the planetary gear assembly is provided in a plurality of sets and each set is driven at a different time, an adjusting screw 10 engaged with the external teeth of the ring gear 4 is provided on the mounting frame 2. The time for which the rotary plate 6 of each set of planetary gear assemblies triggers the position switch 7 can be adjusted by rotating the adjusting screw 10 to rotate the ring gear 4. The position detection of various specifications can be realized by adjusting the number of teeth or the number of driving gears 3 in each planetary gear assembly or adjusting the transmission stage number of the planetary gears 5.
The multiple sets of position switches 7 and the multiple sets of planetary gear assemblies are fixed on the front shell 11 by means of a pressure plate 13 and a matched connecting screw 15. An adjusting gasket 14 is arranged between adjacent position switches 7. The front shell 11 and the pressure plate 13 are provided with bearings 9 for limiting the input shaft 1.
The position switch 7 is a self-reset microswitch.
The utility model discloses a device use as follows:
the speed is converted into a certain number of revolutions of the input shaft 1 by the stroke of the equipment (e.g. the lifting stroke of a stage, the moving stroke of a belt in a belt conveyor, the stroke of one or more layers of movement of an elevator, etc.). The input shaft 1 is linked with a planetary gear with a proper matching ratio, the initial position of a boss 6-1 in a rotating plate 6 in the planetary gear set is adjusted, and after the input shaft 1 reaches a certain revolution, a plectrum in a position switch 7 is triggered to realize the stop or reciprocating control of a motor in the equipment.
