The aim of the utility model is to improve the defects, the shape of the utility model is similar to a cylinder, the center is an eccentric shaft, and a cover, a gear, an output disk, etc., are arranged on the shaft; the parts are arranged in a cylinder body which is provided with an inner gear ring and an upper and a lower holes, the gear is engaged with the inner gear ring body, and an upper cover, the gear and the output disk are connected together by a pin sleeve. A rotary hand wheel drives the gear and the output disk to reversely rotate, and a valve plate of a rotary valve can be widely used on the valve or other related transmission mechanisms.
Description
Title of the present utility model is the inner planet gear transmission device, belongs to field of mechanical technique.
The switching mechanism of existing valve, volume is big, and structure is not compact, and input torque is big and output torque is little, and profile is not attractive in appearance yet.
The purpose of this utility model is to improve the switch drive of manually-operated gate, makes its compact structure, and volume is little, beautiful shape, and input torque is little and output torque is big, can be used for the mechanical device of valve and relevant transmission.
Accompanying drawing 1 is the outline drawing of this device, and wherein Z is a front view, and F is plan view (a no handwheel).Accompanying drawing 2 is these structure drawing of device, and wherein P is a sectional view, and Y is a worm's eye view.
Whole device is a cylinder bodily form, its center is eccentric shaft (2), assembling from top to bottom along eccentric shaft has ring handwheel (7), direction board (4), loam cake (3), cylindrical body generating gear (5), cylinder bodily form output disc (6) on it, and loam cake, gear, three parts of output disc are installed in the cylinder body (1).Eccentric shaft (2) is divided into three sections, and epimere cooperates the stage casing with this device loam cake (3)---and eccentric part cooperates with gear (5), and the hypomere insertion is arranged in the last hole of the output disc below the gear.Epimere is formed main center line by loam cake, hypomere by output disc and body two sections cylindrical hole, and the stage casing is by eccentric, but the engagement of the ring gear of handsetting gear and body.In addition, on eccentric shaft epimere and loam cake hole, stage casing and gear hole, hypomere and the output disc between the hole, all stud with axle sleeve (14), lubricate makes it easy to action.Tubular output disc (6, its first half is only the cylinder bodily form strictly speaking, lower half portion has a sub-elliptical) go up the plane along certain circumference insertion four pin covers (8), withstand between loam cake and the output disc, and leave certain end clearance, gear (5) can freely be rotated between loam cake and output disc.Simultaneously, in the middle of each pin cover, insert socket head screw (9), direction board (4), loam cake (3) gear (5) and output disc (6) are linked together, can under the drive of gear rotation, rotate.Gear is that central authorities have cylindrical hole, the cylindrical gear of tooth arranged outward, between loam cake and output disc, hole that it is central and eccentric shaft stage casing eccentric part closely cooperate, external tooth is meshed with the body internal tooth, its upper edge necessarily is evenly distributed in four garden cylindrical holes, the aperture is bigger slightly than pin cover external diameter, allows four pin covers pass therebetween.Body (1) is a columnar housing, ring gear and two inner cylinder shape holes are up and down arranged, with fixed cover, output disc (6), to go up from the core component to the whole device of output disc under the loam cake and be contained in its inside, the external tooth of gear is meshed with the body internal tooth.At loam cake and body inner circumference, loam cake and eccentric pivot hole, output disc and body inner circumference mating part all have seal ring (11), four altogether, scurry into destructions such as the inner generation of device corrosion with waterproof, vapour and other material.There are four screws (12) transmission device body bottom surface, during use and the valve body of valve link together with four bolts.The rotatingshaft of hole (13) and valve links together by key under the output disc simultaneously.The body lower side also has two stop screws (10), and it act as restriction output disc rotation angle, and its scope has so just been controlled the open and close of butterfly valve between 0-90 °, finished this device and cooperated the control action that reaches pipeline with butterfly valve.
Handwheel (7) is installed in eccentric shaft (2) upper top, casts scale on the conical surface of body top, so that by direction board (4) indication valve opening angle and operating position.
Course of action: manual force is rotated the middle eccentric shaft (2) of this device by handwheel, ring gear engagement rotation on eccentric circle handsetting gear on the eccentric shaft and the body, revolve that to move direction opposite with the handwheel rotation direction, four pore area untie-sell son covers (8) on it are crossed by the Mobile Communication of revolving of gear, driving output disc and loam cake rotates together, on arrow indicating valve family of power and influence plate on the indicator panel that covers open and close angle, the following hole (13) of output disc drives the rotating shaft rotation of valve by key simultaneously, the rotation of rotating shaft drives valve plate and opens or throttle down, and indicator panel upward arrow and valve plate are synchronous.
The utility model volume is little, compact structure, and input torque is little and output torque is big, thereby laborsaving, profile is better appearance also, can use on valve or relevant some gearings, effect is very good.
