Abstract
The utility model provides a one-way damping roller. The one-way damping roller comprises a roller shell, two end covers and a central shaft, wherein the two end covers are respectively arranged at two ends of the roller shell; a hollow shaft is arranged between the roller shell and the central shaft and sleeved in the roller shell; the two ends of the hollow shaft are respectively arranged into inner holes of the end covers, so the roller shell, the end covers and the hollow shaft form a relatively-closed cavity; the cavity is filled with viscous oil; a one-way bearing is arranged in each of the inner holes at the two ends of the hollow shaft; and the central shaft is arranged in the inner holes of the one-way bearings. The one-way damping roller is simple in structure and reliable in operation, and can apply one-way damping force to 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 roller for roller conveyor or feedway (also being " roller ").
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 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 is the shortcoming that overcomes prior art, and a kind of unidirectional damping roller that can produce to the goods on the rollgang unidirectional damping power is provided.
Technical solution of the present utility model is: it comprises roller housing, end cap and center shaft, two end cap is installed on respectively roller housing two ends, between roller housing and center shaft, be provided with hollow shaft, described hollow shaft sleeve is in the roller housing, its two ends are installed on respectively in the endoporus of end cap, so form the cavity of a relative closure between roller housing, end cap and the hollow shaft, fill up thick grease in the described cavity, also be separately installed with an individual event bearing in the endoporus at hollow shaft two ends, center shaft is assemblied in the endoporus of individual event bearing.
Principle of work: when roller housing left-hand revolution, because the unilateral bearing anticlockwise direction in the hollow shaft is locking state, thereby hollow shaft can't rotate, the roller housing can only rotate with respect to hollow shaft, at this moment the thick grease that is filled between roller housing and the hollow shaft will produce viscous force, hinder its rotation, thereby slow down roller housing velocity of rotation, and then the goods on the rollgang is produced dumping force; When roller housing clickwise, because the unilateral bearing clockwise direction in the hollow shaft is free state, thereby the roller housing drives hollow shaft and freely rotates under the effect of grease viscous force, at this moment not to the rollgang deposits yields dumping force of getting in stocks.
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 hollow shaft structure scheme drawing of the present utility model.
Fig. 3 is roller housing structure scheme drawing 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.
As shown in Figure 1, 2, 3, roller housing 6 internal layers are metallic material, and outer is non-metallic material (being commonly called as encapsulate).An end cap 3 is respectively installed at roller housing 6 two ends, between roller housing 6 and center shaft 2, be provided with hollow shaft 5, described hollow shaft 5 is enclosed within the roller housing 6, its two ends are installed in the endoporus of end cap 3, so form the cavity of a relative closure between roller housing 6, end cap 3 and the hollow shaft 5, fill up thick grease in this cavity.Roller housing 6 inwalls of present embodiment also are provided with one or more strip projected parts 7.Be separately installed with an individual event bearing 4 in the endoporus at hollow shaft 5 two ends, center shaft 2 is assemblied in the endoporus of individual event bearing 4.Center shaft 2 ends of present embodiment also are fixed with connecting panel 1.
As shown in Figure 4, the utility model is mounted on the rollgang 8 and uses.When goods 9 slides through the utility model along the direction of arrow, drive roller housing 6 left-hand revolutions, because unilateral bearing 4 anticlockwise directions in the hollow shaft 5 are locking state, thereby hollow shaft 5 can't rotate, roller housing 6 can only be with respect to hollow shaft 5 rotations, and the thick grease that at this moment is filled between roller housing 6 and the hollow shaft 5 will produce viscous force, hinders its rotation, thereby slow down roller housing 6 velocities of rotation, and then the goods 9 on the rollgang 8 is produced dumping force.When goods 9 slides through the utility model along the arrow opposite sense, drive roller housing 6 clickwises, because unilateral bearing 4 clockwise directions in the hollow shaft 5 are free state, thereby roller housing 6 drives hollow shaft 5 and freely rotates under the effect of grease viscous force, at this moment goods on the rollgang 89 do not produced dumping forces.
