Description
Technical field:
The present invention relates to conveyer or the feedway of mechanical field, the particularly drive disk assembly of conveyer or feedway, concrete is a kind of cylinder for roller conveyor or feedway.
Background technology:
In gravity type boat davit roller conveyor or feedway, in order to limit the slip velocity of goods, guarantee that the goods conveying operates steadily and safety, the way of generally taking is: 1, reduce the roller-way bevel angle or one section level buffering roller-way is set on the inclined-plane roller-way; 2, shorten roller-way conveyor surface length; 3, retaining means is installed on roller-way.These three kinds of methods can play a role, but exist reliability not high, limit and reduced the disadvantages such as conveying usefulness.For this reason, Huzhou Dema Machinery Co., Ltd's (this enterprise is the first majority shareholder of the applicant unit) had once designed a kind of speed limit damping cylinder, and applied for utility model patent (ZL01252973.7 Damping rolling cylinder), it has the roller housing, end cap and end-cover axle, be connected with center shaft between central shaft hole on the inner built-in bottom surface with closely being embedded in the roller inner walls of the end-cover axle of roller housing one end, the center gear of planetary gear set is installed on center shaft, each planetary wheel of planetary gear set is meshed with the internal tooth of built-in cylinder simultaneously, be respectively fitted with gravity block by two, the centrifugal brake that the centrifugal fin of friction shoe and centre tooth wheel set form, its center gear pair movable set is on center shaft, and be meshed with sun gear or the planetary wheel of planetary gear set.During work, the sliding velocity of goods on roller-way is faster, and the resistance that the Damping rolling cylinder centrifugal braking device produces is just larger, thereby plays the effect that reduces the goods sliding velocity.This Damping rolling cylinder is rational in infrastructure, can greatly improve usefulness and the safe reliability of gravity type boat davit roller-way conveying articles.But all be subject to dumping force because goods after this Damping rolling cylinder of application advances or retreats on roller-way, thereby be not suitable for the rollgang that needs unidirectional damping.
Summary of the invention:
The purpose of this invention is to provide a kind of unidirectional damping cylinder that is different from above-mentioned Damping rolling cylinder, this cylinder can produce unidirectional damping power to the goods on rollgang.
Technical solution of the present invention is: it comprises drum housing and end cap, the drum housing inwall be provided with can with the internal tooth of planetary wheel tooth mesh, in drum housing one end and end cap, bearing all is installed, be connected with center shaft between each bearing bore, near midway location, unilateral bearing and bearing seat are installed at center shaft, planetary wheeling assembly is arranged on the end face of bearing seat, the sun gear movable set of planetary wheeling assembly is on center shaft, each planetary wheel is meshed with the internal tooth of drum housing simultaneously, by two, clump weight is housed respectively, the centrifugal brake that the centrifugal fin of friction shoe and sun gear form, its sun gear also movable set on center shaft, and be meshed with the planetary wheel of planetary gear set.
The present invention is simple in structure, and reliable operation can produce the one direction dumping force to the goods on rollgang.
The accompanying drawing explanation:
Fig. 1 is stereo decomposing structural representation of the present invention.
Fig. 2 is planetary gear set stereo decomposing structural representation of the present invention.
Fig. 3 is centrifugal brake stereo decomposing structural representation of the present invention.
Fig. 4 is that the present invention uses view.
The specific embodiment:
Below in conjunction with accompanying drawing, with embodiment, the invention will be further described.
As shown in Figure 1, Figure 2, Figure 3 shows, drum housing 1 is by the engineering-plastics integral injection mo(u)lding, its inwall be provided with can with the internal tooth of planetary wheel 10,15 tooth mesh, drum housing 1 one ends are equipped with bearing 2, other end assembling end cap 8, bearing 9 is housed in end cap 8, between bearing 2 and bearing 9 endoporus, is connected with center shaft 3, at center shaft 3, near midway location, unilateral bearing 4 and bearing seat 5 are installed.The planetary wheeling assembly 6 of the present embodiment consists of two groups of satellite gears, wherein the wheel carrier 12 of one group of satellite gear is fixed on the end face of bearing seat 5 by bearing pin 11, on wheel carrier 12 around uniform three planetary wheels 10 of center shaft 3, sun gear 13 movable sets of another group satellite gear mesh on center shaft 3 and with each planetary wheel 10 of last group of satellite gear, the a pair of planetary wheel 15 be arranged on centre tooth wheel carrier 14 meshes with the sun gear 16 of centrifugal brake 7, and the planetary wheel 10 of described planetary wheeling assembly and planetary wheel 15 also are meshed with the internal tooth of drum housing 1 simultaneously.Centrifugal brake 7 by sun gear 16, support 17, clump weight 18, centrifugal fin 19, sell 20, friction shoe 21, baffle plate 22, bearing pin 23 etc. form.The sun gear 16 of the present embodiment is connected by the engineering-plastics integral injection mo(u)lding and with support 17, two centrifugal fins 19 of falcate that clump weight 18, friction shoe 21 are housed respectively respectively have an end to be movably arranged on support 17 by bearing pin 23, the two ends of two centrifugal fins 19 also are respectively equipped with hook 24, between adjacent hook, are connected with extension spring.
As shown in Figure 4, the present invention is mounted on rollgang 25 and uses.When goods 26 slides when of the present invention along the direction of arrow, drive drum housing 1 clickwise, because unilateral bearing 4 clockwise directions in bearing seat 5 are free state, thereby drum housing 1 drives the non-resistance rotation together of planetary wheeling assembly 6, centrifugal brake 7, bearing seat 5 with its internal tooth, at this moment, the unidirectional damping cylinder does not produce dumping force to goods.When goods 26 slides when of the present invention along the arrow opposite sense, drive drum housing 1 left-hand revolution, because unilateral bearing 4 anticlockwise directions in bearing seat 5 are locking state, thereby bearing seat 5 and the wheel carrier 12 that is arranged on its end face can't rotate, drum housing 1 can only drive the planetary wheel rotation with its internal tooth, planetary wheel drives again centrifugal brake 7 and accelerates rotation, when centrifugal brake 7 reaches certain speed, its centrifugal fin 19 opens, make friction shoe 21 and the interior wall friction of drum housing 1, hinder its rotation, play drum housing 1 velocity of rotation that slows down, and then the effect of restriction goods 26 coasting speeds.
