Detailed Description
Example 1
Referring to fig. 1 to 5, a planet rack 90-degree linear reciprocating mechanism comprises a base, wherein a gear ring is arranged on one side of the base, a rotating shaft is arranged in the base, a gear is arranged at one end of the rotating shaft, the gear is meshed with the gear rack, a planet gear (three) is arranged at the other end of the rotating shaft, the outer side of the planet gear is meshed with the gear ring, the inner side of the planet gear is meshed with a sun gear, and a planet carrier is arranged at the sun gear.
In an embodiment, the rack has a bar portion, a groove is formed in the bar portion, a through hole is formed in the bottom of the groove, a tooth portion is formed in the bottom of the bar portion, and a connecting portion is formed between the bar portion and one end of the bar portion.
The working principle is as follows: the driving motor realizes a speed reduction function by using a planetary gear train (the driving motor drives a sun gear in the planetary gear train, the sun gear drives a planetary gear and further drives a rotating shaft), and the output realizes 90-degree linear reciprocating output by using a gear and a rack (the rack is used for driving a valve rod of the vehicle-mounted thermostat in a reciprocating mode).
For the sake of brevity, the description of the prior art is omitted herein.
Example 2
The basic structure is the same as embodiment 1, except that a plurality of blind holes are arranged on the outer side of the base, and the number of the blind holes is the same as the number of the groups of the planetary gears. In the embodiment, the number of the groups of the planetary gears is one, and the number of the blind holes is one. The number of groups of the internal planetary gears can be known through the number of the blind holes, and the model of the mechanism is judged by auxiliary internal workers under the condition of no nameplate and no disassembly.
Above only do the preferred embodiment of the present invention, the protection scope of the present invention is not limited to the above embodiment, all belong to the technical scheme of the present invention all belong to the protection scope of the present invention. For those skilled in the art, several modifications can be made without departing from the principle of the present invention, and such modifications should also be considered as the protection scope of the present invention.
