Description
Technical field
This utility model is related to a kind of brake gear of rotating shaft.
Background technology
Rotating shaft is the indispensable drive disk assembly of most of actuating devices, and the mechanism being connected with rotating shaft is due to work operating
After needing or breaking down, cut-out power set are needed so that rotating shaft is stopped operating, due to cutting off power set, rotating shaft is in and is not subject to
The free state of constraint, is susceptible to rotate when by external force, there is potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is：In order to overcome deficiency of the prior art, this utility model carries
For a kind of brake gear of rotating shaft.
This utility model solves its technical problem technical scheme to be taken：A kind of brake gear of rotating shaft, including
The fixing friction plate mating with rotating shaft of connecting plate on the supporting plate and the cylinder driving friction plate motion, described connecting plate
Place plane is parallel with shaft axis, and described friction plate is provided with the circular arc friction plate mating with rotating shaft excircle radian, and
, positioned at the both sides of rotating shaft, cylinder one end is connected with connecting plate, and the other end is connected with friction plate, cylinder for described connecting plate and friction plate
Friction plate is driven so that friction plate is compressed with rotating shaft and separate.Because connecting plate and friction plate are located at the both sides of rotating shaft, cylinder drives
Friction plate, near rotating shaft, makes friction plate and shaft contacts, realizes brake stop by the frictional force between friction plate and rotating shaft.
Further, described friction plate is rectangular slab, and described cylinder is four, and four described cylinders are located at friction plate respectively
On four angles, and position is symmetric.The cylinder being symmetrically distributed on four angles of rectangle friction plate can make friction plate and turn
Uniform force between axle, increases the service life.
Preferably, described friction plate center of circle angle range is 120 ° -180 °.Friction plate maximum not can exceed that 180 °, otherwise gas
Cylinder cannot drive friction plate to lift.
Further, in order to ensure to be provided that enough frictional force, described friction plate and friction plate in shaft axis direction
Length is equal to the girth of rotating shaft excircle.Because the external diameter of rotating shaft is of different sizes, therefore in order to ensure different thicknesses rotating shaft all
Sufficiently large frictional force can be obtained, limit the contact length of rotating shaft and friction plate.
The beneficial effects of the utility model are：A kind of brake gear of rotating shaft that this utility model provides, using friction plate
Frictional force and rotating shaft between realizes the stop of rotating shaft, enables rotating shaft to be maintained at specific position and does not arbitrarily rotate, it is to avoid peace
Full hidden danger, structure is simple, and stopping effect is good.
Brief description
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of this utility model most preferred embodiment；
Fig. 2 is the structural representation of this utility model most preferred embodiment.
In figure：1st, rotating shaft, 2, gripper shoe, 3, bearing, 4, screw, 5, connecting plate, 6, friction plate, 7, cylinder, 8, friction plate.
Specific embodiment
Presently in connection with accompanying drawing, this utility model is described in detail.This figure is the schematic diagram simplifying, only in a schematic way
Basic structure of the present utility model is described, therefore it only shows the composition relevant with this utility model.
As shown in Figure 1-2, the brake gear of a kind of rotating shaft of the present utility model, rotating shaft 1 two ends are equipped with brake gear,
Fagging 2 be two parallel and be symmetricly set on rotating shaft 1 two ends, rotating shaft 1 is passed through bearing 3 and is connected with gripper shoe 2 rotation, brake gear
The friction plate 6 being mated with rotating shaft 1 including the connecting plate 5 being fixed in gripper shoe 2 by screw 4 and driving friction plate 6 are moved
Cylinder 7, described connecting plate 5 place plane and rotating shaft 1 diameter parallel, described friction plate 6 is provided with and rotating shaft 1 excircle radian
The circular arc friction plate 8 of coupling, friction plate 6 is provided with circular groove, and friction plate 8 is fixed in arc groove, and described company
, positioned at the both sides of rotating shaft 1, cylinder 7 one end is connected with connecting plate 5, and the other end is connected with friction plate 6, cylinder for fishplate bar 5 and friction plate 6
7 drive friction plates 6 make friction plate 8 compress with rotating shaft 1 and separate.Because connecting plate 5 and friction plate 6 are located at the both sides of rotating shaft 1, gas
Cylinder 7 drives friction plate 6 near rotating shaft 1, so that friction plate 8 is contacted with rotating shaft 1, real by the frictional force between friction plate 8 and rotating shaft 1
Now brake stop.As long as connecting plate 5 and friction plate 6 position be oppositely arranged on the circumferential both sides of rotating shaft 1, as left and right sets
Put, setting up and down or be obliquely installed, in the present embodiment, connecting plate 5 is located at the underface of rotating shaft 1, and friction plate 6 is just being located at rotating shaft 1
Top, cylinder 7 drives friction plate 6 to move up and down.
Described friction plate 6 is rectangular slab, and described cylinder 7 is four, and four described cylinders 7 are located at the four of friction plate 6 respectively
On individual angle, and position is symmetric.The cylinder 7 being symmetrically distributed on 6 four angles of rectangle friction plate can make friction plate 8 and turn
Uniform force between axle 1, increases the service life.
Preferably, described friction plate 8 center of circle angle range is 120 ° -180 °.Friction plate 8 maximum not can exceed that 180 °, otherwise
Cylinder 7 cannot drive friction plate 6 to lift.
In order to ensure to be provided that enough frictional force, described friction plate 6 and friction plate 8 length in rotating shaft 1 axis direction
Girth equal to rotating shaft 1 excircle.
Operation principle：
When rotating shaft 1 needs stop, four cylinders 7 bounce back simultaneously, drive friction plate 6 to move downward, and make friction plate 8 and turn
Axle 1 is close and contacts, and produces frictional force, cylinder 7 continues retraction, between friction plate 8 and rotating shaft 1 between friction plate 8 and rotating shaft 1
When generation frictional force is sufficiently large, realize the stop of rotating shaft 1.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related work
Personnel can carry out various change and modification completely in the range of without departing from this utility model.This utility model
The content that technical scope is not limited in description it is necessary to determine its technical scope according to right.
