Description
Technical field
The utility model relates to a kind of frequency conversion clutch, especially relates to a kind of frequency conversion clutch of fine module gear.
Background technique
In frequency conversion clutch designs process, a development trend is exactly by outputting power after gearbox speed reduction by variable-frequency motor.When gear box designs, usually choose the train of gearings that modulus is more than or equal to 1.Modulus refers to the ratio of tooth pitch between adjacent two gear teeth homonymy flank profils and Ratio of the circumference of a circle to its diameter.Modulus is larger, and the gear teeth are higher also thicker.If the number of teeth of gear is certain, modulus is larger, then the radial dimension of taking turns is also larger.Therefore in the design of gear-box, select large module gear, demand and the requirement of strength of reduction speed ratio can be ensured.But the train of gearings that modulus is larger also limit the size of whole system, be unfavorable for Appropriate application and the cost control in space.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of frequency conversion clutch of fine module gear, can Appropriate application, power transmission steady.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of frequency conversion clutch of fine module gear, comprise variable-frequency motor and gear assembly, described gear assembly comprises sun gear, internal gear and three planetary pinions, described sun gear, internal-gear and planetary pinion are fine module gear, described sun gear is positioned at the central position of described internal gear, three described planetary pinions are positioned at described internal gear and are evenly distributed on the periphery of sun gear, described planetary pinion engages with described sun gear, described internal-gear engages with planetary pinion, three planet carriers are provided with in described internal gear, a planet carrier is provided with between every two planetary pinions, described planet carrier is connected to sun gear and planetary pinion, described variable-frequency motor is connected with described sun gear.
The central position of described sun gear is provided with the through hole adapted with planet carrier, described planetary central position is provided with the through hole adapted with planet carrier, described planet carrier comprises upper-part and lower component, described upper-part is parallel with lower component and connected by middle parts, described middle parts are mutually vertical with upper-part, described upper-part penetrates in planetary through hole, and described lower component penetrates in the through hole of sun gear.Utilize planet carrier to be connected with planetary pinion by sun gear, planetary pinion can rotate along sun gear while own rotation.
The modulus of described sun gear is less than 1mm, and described planetary modulus is less than 1mm, and the modulus of described internal gear is less than 1mm.All gears in gear assembly are the close-toothed gear of choice for use all, and effectively can reduce the use of material, construction cost is lower.
The diameter of described sun gear is less than described planetary diameter, and described planetary diameter is less than the diameter of described internal gear.To planetary pinion, sun gear, the making rational planning for of internal gear, make the structure of whole device more reasonable, be conducive to the Appropriate application to space.
Compared with prior art, the utility model has the advantage of that sun gear is positioned at the central position of internal gear, three planetary pinions are positioned at internal gear and are evenly distributed on the periphery of sun gear, the reasonable arrangement of sun gear, internal gear and planet tooth quilt.Connect sun gear and planetary pinion by planet carrier again, allow planetary pinion rotate around sun gear while own rotation.Space of the present utility model obtains Appropriate application, and all gears all adopt fine module gear simultaneously, and construction cost is lower.Variable-frequency motor has sun gear to connect, and after sun gear is slowed down by epicyclic train, transferring power is to planet carrier, and final completion system exports, and makes the Power output of whole device steady.
