Abstract
A one-way damping roller comprises a roller shell and an end cap. An internal tooth capable of being meshed with planetary gear teeth is arranged on the inner wall of the roller shell. One end of the roller shell and the inner side of the end cap are both provided with a bearing. A central shaft is connected between inner holes of the bearings. A one-way bearing and a bearing seat is installed on a position of the central shaft close to the middle of the central shaft. A planetary wheel assembly is installed on the bear seat end face vertical to the central shaft. A sun gear of the planetary wheel assembly is movably sleeved on the central shaft. Planetary gears are simultaneously meshed with the internal tooth of the roller shell. A centrifugal brake is composed of a centrifugal fin and a sun gear, wherein the centrifugal fin and the sun gear are respectively provided with a counter weight block and a friction block. The sun gear of the centrifugal brake is also sleeved on the central shaft, and is meshed with the planetary gears of the planetary wheel assembly. The one-way damping roller is simple in structure, reliable in operation, and capable of producing one-way damping force for goods on a conveying roller way.
Description
Technical field:
The utility model relates to conveyer or the feedway of mechanical field, the particularly drive disk assembly of conveyer or feedway, and 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 at the inclined-plane roller-way one section level buffering roller-way is set; 2, shorten roller-way conveyor surface length; 3, at roller-way retaining means is installed.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, between the 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, be connected with center shaft, the center gear of planetary gear set is installed on the 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 consist of, its center gear pair movable set and is meshed with sun gear or the planetary wheel of planetary gear set on center shaft.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 owing to goods behind this Damping rolling cylinder of application advances or retreats at roller-way, thereby be not suitable for the rollgang that needs unidirectional damping.
Summary of the invention:
The purpose of this utility model provides a kind of unidirectional damping cylinder that is different from above-mentioned Damping rolling cylinder, and this cylinder can produce unidirectional damping power to the goods on the rollgang.
Technical solution of the present utility model 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 is installed all, 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 installed 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 consist of, its sun gear also movable set and is meshed with the planetary wheel of planetary gear set on center shaft.
The utility model is simple in structure, and reliable operation can produce the one direction dumping force to the goods on the rollgang.
Description of drawings:
Fig. 1 is stereo decomposing structural representation of the present utility model.
Fig. 2 is planetary gear set stereo decomposing structural representation of the present utility model.
Fig. 3 is centrifugal brake stereo decomposing structural representation of the present utility model.
Fig. 4 is that the utility model uses view.
The specific embodiment:
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
Shown in figure one, figure two, figure three, 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 the end cap 8, is connected with center shaft 3 between bearing 2 and bearing 9 endoporus, near midway location unilateral bearing 4 and bearing seat 5 are installed at center shaft 3.The planetary wheeling assembly 6 of the present embodiment is made 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, center on center shaft 3 uniform three planetary wheels 10 on the wheel carrier 12, sun gear 13 movable sets of another group satellite gear on center shaft 3 and with each planetary wheel 10 engagements of last group of satellite gear, be installed in sun gear 16 engagements of a pair of planetary wheel 15 and centrifugal brake 7 on the centre tooth wheel carrier 14, 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 is comprised of sun gear 16, support 17, clump weight 18, centrifugal fin 19, pin 20, friction shoe 21, baffle plate 22, bearing pin 23 etc.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 the support 17 by bearing pin 23, the two ends of two centrifugal fins 19 also are respectively equipped with hook 24, are connected with extension spring between the adjacent hook.
Shown in figure four, the utility model is mounted on the rollgang 25 and uses.When goods 26 slides through the utility model along the direction of arrow, drive drum housing 1 clickwise, because unilateral bearing 4 clockwise directions in the bearing seat 5 are free state, thereby drum housing 1 drives the together non-resistance rotation 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 through the utility model along the arrow opposite sense, drive drum housing 1 left-hand revolution, because unilateral bearing 4 anticlockwise directions in the bearing seat 5 are locking state, thereby bearing seat 5 and the wheel carrier 12 that is installed 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 drum housing 1 interior wall friction, hinder its rotation, play drum housing 1 velocity of rotation that slows down, and then the effect of restriction goods 26 coasting speeds.
