Abstract
A roller damper belongs to the technology field of gravity roller conveyor, in which the inside of a cylindrical shell is provided with a planetary wheel set and a centrifugal brake composed of a centrifugal fin assembled with a gravity block and a friction block and a centre gear pair. The centre gear pair of the centrifugal brake is meshed with the centre gear or planetary gear of the planetary wheel set. Each planetary gear of the planetary wheel set is meshed with the annular gear arranged on the inner wall of the cylindrical shell at the same time. The entire cylindrical shell is fixed on two vertical sash bars through an end cap axis and a central axis. Two horizontal sash bars of the rectangular framework parallel to the central axis are respectively linked with a tension spring. The outer surface of the cylindrical shell is coated with the materials with high strength, large friction coefficient and good wear resistance. The installation and use of the utility model is flexible and convenient. With stable damping and lower manufacturing costs, the utility model is particularly suitable for the roller conveyor with lighter loads.
Description
Technical field
The utility model belongs to the roller conveyor technical field.
Background technology
At present on unpowered gravity type boat davit roller conveyor, slip velocity for the restriction conveying object, make gravity type boat davit carry the comparatively steady and safety of operation, the way of generally taking is: 1. reduce the bevel angle of rollgang or set up one section level buffering roller-way on the inclined-plane roller-way; 2. shorten conveyer roller-way length.But said method has all limited the usefulness of conveyer to a certain extent.For this reason, the applicant had once designed " Damping rolling cylinder " (number of patent application is 01252973.7) with direct damping function and automatically regulating dumping force.It is that two groups of satellite gears and centrifugal brake are installed in the roller, and when roller under the load effect of gliding fast and during high speed revolution, the centrifugal brake in the roller has blocked the high speed revolution of roller, thereby has slowed down the quick slip velocity of load.This Damping rolling cylinder damping is timely, the usefulness height, and reliable and safe operation, but manufacturing cost is higher, mainly is applicable on the heavy duty rollgang.
Summary of the invention
The purpose of this utility model provides a kind of adding and is installed on the gravity type boat davit rollgang, and is flexible and convenient to use, is specially adapted to the roller-way damper than underload gravity type boat davit rollgang.
The technical solution of the utility model is: it has circular cylindrical shell, by center shaft planetary gear set is installed in the circular cylindrical shell, each planetary wheel of planetary gear set is meshed with the set internally toothed annulus of circular cylindrical shell inwall simultaneously, by being equipped with gravity block, the centrifugal brake that the centrifugal fin of friction shoe and centre tooth wheel set constitute, its center gear pair movable set is on center shaft, and be meshed with the sun gear or the planetary wheel of planetary gear set, and the outside face of circular cylindrical shell is enclosed with the intensity height, friction coefficient is big, the material that the antifriction performance is good, or directly make circular cylindrical shell by this class material, whole circular cylindrical shell is fixed on two vertical mouldings of rectangular framework by end-cover axle and center shaft, and with two horizontal mouldings of the rectangular framework of central axes on be connected with extension spring respectively.
Description of drawings
Accompanying drawing 1 is an overall structure scheme drawing of the present utility model.
Accompanying drawing 2,3,4 is respectively A-A, B-B, the C-C cross-sectional view of accompanying drawing 1.
Accompanying drawing 5,6 is installed on structural representation on the roller-way for the utility model.
The specific embodiment
The shell of roller-way damper is the short cylinder housing of being made by engineering plastics 3, and the one end is provided with fixedly end cap 4, and the other end is provided with the movable end cap 11 of installing; Circular cylindrical shell 3 inwalls are shaped on one section internally toothed annulus 16, and the circular cylindrical shell appearance is enclosed with rubber 2.The present embodiment planetary gear set is made up of two groups of satellite gears 7,9, the wheel carrier 20 of planetary gear set 7 is fixed on the inner of the fixing hollow shaft 5 at end cap 4 centers, on wheel carrier 20, be evenly equipped with three planetary wheels 19 around hollow shaft 5, the sun gear 21 of planetary gear set 9 is meshed simultaneously with three planetary wheels 19 of planetary gear set 7, the a pair of planetary wheel of installing on support 17 back sides of sun gear 21 18 then is meshed with the centre tooth wheel set 15 of centrifugal brake 10, and a pair of planetary wheel 18 and three planetary wheels 19 also are meshed with the internally toothed annulus 16 of circular cylindrical shell simultaneously; Be connected with two centrifugal fins 13 that are equipped with gravity block 14 and friction shoe 12 on one end face of centrifugal brake centre tooth wheel set 15; Center shaft 6 passes the sun gear 21 of centrifugal brake centre tooth wheel set 15 and planetary gear set 9, the one end is set in the hollow shaft 5 of planetary gear set 7 and fixing end cap 4, after the other end passes movable installation end cap 11, be fixedly connected with a vertical moulding of rectangular framework 1, the vertical moulding of another of rectangular framework 1 then is fixedly connected with an end of hollow shaft 5, and is connected with extension spring 8 respectively on the two horizontal mouldings of the rectangular framework 1 that parallels with center shaft 6.The utility model is installed on the bottom of rollgang by the fixed link 22 that extension spring 8 connects on the roller-ways, and the appearance of two adjacent rollers 23 on damper circular cylindrical shell appearance and the roller-way is more closely contacted.When the roller-way normal operation, the rotation of roller 23 drives this damper circular cylindrical shell 3 and relatively rotates, and when roller 23 is subjected to the load of certain speed downslide on the roller-way to promote to add the piece rotation, damper circular cylindrical shell 3 twirl have also been driven, circular cylindrical shell 3 drives planetary gear set 7 by its internally toothed annulus 16,9 high speed revolutions, planetary gear set 7,9 drive centrifugal brake 10 rotations again, when centrifugal brake reaches certain rotating speed, its two centrifugal fin launches, make friction shoe 12 and circular cylindrical shell 3 inwall contact frictions, the rotation that circular cylindrical shell 3 has been delayed in resistance, also just increased the contact resistance between roller 23 and the damper circular cylindrical shell 3, thereby slowed down the velocity of rotation of roller 23, and then slowed down the downslide delivery speed of load, gradually returned to permanent speed subsequently.
The utility model is to be installed on the gravity transfer roller-way with whenever keeping at a certain distance away, and each damper acts on two rollers, so damping ratio is more steady, and the utility model installs and uses flexiblely, is particularly suitable for more underloaded gravity transfer roller-way.
