The existing typical apply of casehistory the utility model in tinuous production:
In actual production line, often requiring that namely the chassis of convey materials can linearly travel, also can turning by continuing after bend linearly to travel, also can need according to action and carry along space curve.Permanent magnetism helicoidal gear of the present utility model can realize such function by contactless worm drive.Now enumerate typical embodiment to be described.
Embodiment 1: Linear transmission
As is illustrated by figs. 11 and 12, universal permanent magnetic transmission device described in the utility model, mainly comprise magnetic nut 1, guide rail 10, motor 11, leading screw 12, bearing seat 13 and bearing 20, described leading screw 12 is connected with the output shaft of motor 11, be fixed on bearing seat 13, the two ends of leading screw 12 also can flexible rotating by supporting with the bearing 20 in bearing seat 13.
Described leading screw 12 is by outwardly and form along the spiral-distributed external thread structure of its axis direction around its circumferential surface, and leading screw 12 is single head or bull, and head number is preferably even number, and leading screw 12 material is magnetic conductive material.Leading screw 12 threaded portion cross section can be square-section, also can be trapezoid cross section, also can be other cross sections.
The outer symmetrical of leading screw 12 arranges 2 aforesaid magnetic nuts 1, described magnetic nut 1 inside be the external threaded surface arranged relative relative with described leading screw 12 to projecting inward permanent magnet, the direction of magnetic pole is that external pole orientation is staggered by N, S magnetic pole.
As shown in figure 12, the face of cylinder 5 of the depression in the middle part of the magnetic screw thread 2 of magnetic nut 1 is coaxial with the outside thread of leading screw 12, and the externally threaded external diameter of leading screw 12 is less than the diameter on the face of cylinder 5 in the middle part of magnetic screw thread 2, between keep certain magnetic gap.
Also need to keep certain spacing between described motor 11 and described magnetic nut 1, to avoid interference.
Principle of work: because the magnetic force attracted each other between leading screw 12 outside thread and the magnetic screw thread 2 of magnetic nut 1 is very large, be difficult to relativity shift occurs, wherein a helix line can move along another helix line, when the outside thread of leading screw 12 rotates, moving in the direction that magnetic nut 1 will limit along guide rail, realizes contactless worm drive.The both sides that 2 magnetic nuts 1 are symmetrically distributed in leading screw 12 can balance out radial suction, and only have axial thrust.
Embodiment middle guide 10 cross section is I-shape, top is T-shaped, conveying carrier 14 liang of side bottoms arrange locating support 16, locating support 16 is installed track adjusting wheel 15, locating support 16 fixedly mounts magnetic nut 1, track adjusting wheel 15 is divided into vertical track adjusting wheel and horizontal guide sheave to be positioned on guide rail 10 by conveying carrier 14, and makes magnetic nut 1 keep coaxial setting with leading screw 12, can along guide rail 10 easy slide.
Motor 11 rotarily drives leading screw 12 and rotates, by the magnetic force between leading screw 12 and magnetic nut 1, the longitudinal direction of conveying carrier 14 along guide rail 10 is promoted, after magnetic nut 1 surmounts leading screw 12, magnetic nut 1 continues to pass beyond bearing seat 13, motor 11, length due to magnetic nut 1 is greater than the total length of bearing seat 13, motor 11, magnetic nut 1 can keep magnetic drive with leading screw 12 and below above all the time, thus continue to be transferred on next section of leading screw 12, continue worm drive in the manner aforesaid, thus realize the continuous linear conveying of material.
Above-mentioned permanent magnetism helicoidal gear, because magnetic drive part relative area is very large, magnetic force is huge, and not contact between rotor and stator during transmission, thus do not rub generation, and also do not produce high-frequency electromagnetic loss, driving efficiency is close to 100%.
Leading screw 12 and magnetic nut 1 are coaxially arranged, and practical application also may be eccentric, also may be at an angle to each other.This mainly causes by assembly error or when turning.
Embodiment 2: curve transmission
Bearing seat 13 and the bearing 21 at aforesaid motor 11, leading screw 12 and two ends form Linear transmission unit.When Linear transmission unit very in short-term, multiple very short Linear transmission unit can connect and compose the curve of needs in turn, can realize curve transmission in the manner aforesaid.Every section of line segment can control separately, realizes different speed and action.
The utility model also provides a kind of synchronous curve transmission structure.
As shown in figure 13, when guide rail 10 is bend, and when bend does not need complicated action control, universal coupling 18 can be set at adjacent leading screw 12 two ends.The shorter leading screw 12 of multiple length is connected into continuous line segment by universal coupling 18, forms continuous curve.
As shown in figure 14, adjacent leading screw 12 is connected by corner axle bed 17, and the internal installation shaft of corner axle bed 17 holds 21, and the two ends of leading screw 12 are supported by the bearing 21 in adjacent corner axle bed 17, can flexible rotating.Between adjacent leading screw 12, arrange universal coupling 18, each universal coupling 18 is made up of center cross 19 and two jointed shafts 20.Universal coupling 18 also can be the flexible clutch of other types, and kind much repeats no more.
The external diameter of the leading screw 12 of the helicoidal gear of curve transmission is less than the external diameter of straight-line leading screw 12, makes to there is gap between leading screw 1 and magnetic nut 1 larger, can not interfere collision, pass through bend so that smooth and easy in turning process.
Described leading screw 12 or magnetic nut 1 outer setting protecting sleeve, as leading screw outer wrap corrosion-resistant steel cylindrical sleeves, get final product dust-proof anti-collision, can prevent again Korrosionsmedium from corroding, can be used for the Environment space having requirement for anticorrosion.
Described motor 11 also can be other primary mover and drive disk assembly, such as, import external impetus into leading screw 12 with finishing bevel gear cuter and rotate, or to be imported into by external impetus by chain and drive leading screw 12 to rotate.Transmission device should not interfere at linear portion with by during segment of curve with magnetic nut 1.
Above-mentioned two kinds of embodiments combination enforcement can form various solid space curve transmission system, complements one another with other driving systems existing.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and inventive concept thereof and replace or change, all should be encompassed within protection domain of the present utility model.
