Abstract
The utility model discloses a brake band separation rolling mechanism comprising springs, a brake band and two cylindrical pins. The two cylindrical pins are respectively fixed on the brake band, and fixing nuts are arranged on the upper portions of the cylindrical pins. The springs are respectively sleeved on the cylindrical pins. A connection plate is arranged between the lower portions of the two cylindrical pins. The connection plate is connected with the lower ends of the springs, and a rolling wheel is arranged in the middle of the connection plate. An opening is arranged in the middle of the brake band. Through addition of the rolling wheel, the brake band separation rolling mechanism can reduce contact area between the brake band and a brake hub in a non-braking state, decreases friction force, and reduces consumption of system power.
Description
Technical field
The utility model relates to a kind of brake band and breaks away from rolling mechanism.
Background technology
The brake band device of winch comprises spring, brake band and thru-bolt in the market, and two thru-bolts are separately fixed at above the brake band, and winch brake power is big more; Required brake band diameter and bandwidth are big more, and when brake weight up to tens tons up to a hundred tons the time, the size of whole brake band can be quite big; It is very big that weight also becomes thereupon; During winch work, the spring on the thru-bolt can be stressed and can the deadweight of stretching, extension brake band force brake band to contact with brake hub, produces friction; Influence winch speed and moment of torsion transmission, increase system power dissipation greatly.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of brake band to break away from rolling mechanism, can under the state of brake, reduce brake band and brake hub area of contact, and the power of reducing friction reduces system power dissipation.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of brake band breaks away from rolling mechanism, comprises spring, brake band, two thru-bolts; Two thru-bolts are separately fixed at above the brake band; Thru-bolt top is provided with captive nut, and spring housing is on thru-bolt, and two thru-bolt bottoms are provided with connecting panel; The connecting panel two ends have circular hole and are inserted in thru-bolt; And with spring under end in contact, through bearing roller is housed also in the middle of the connecting panel, be provided with opening in the middle of the brake band.
Further, the thru-bolt of connecting panel bottom also is equipped with setting nut.
The beneficial effect of the utility model is: the utility model has increased roller, can make reduction brake band and brake hub area of contact under the state of winch brake, and the power of reducing friction reduces system power dissipation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, spring, 2, thru-bolt, 3, captive nut, 4, roller, 5, brake band, 6, connecting panel, 7, bearing, 8, setting nut.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
As shown in Figure 1, a kind of brake band breaks away from rolling mechanism, comprises spring 1, brake band 5, thru-bolt 2; Thru-bolt 2 has two to be separately fixed at above the brake band 5, and each thru-bolt 2 top is provided with captive nut 3, and spring 1 is enclosed within on the thru-bolt 2; Be provided with connecting panel between two thru-bolt 2 bottoms; Connecting panel 6 two ends have circular hole, and thru-bolt 2 is enclosed within the circular hole, also are equipped with through bearing 7 bonded assembly rollers 4 in the middle of the connecting panel 6; Be provided with the opening that roller 4 is installed in the middle of the brake band 5, connecting panel 6 two ends contact with spring 1 lower end 3.
As the improvement of the utility model, on the thru-bolt 2 of connecting panel 6 bottoms, setting nut 8 is housed also, so improve, can controlling spring 1 downstream position, can regulate roller 4 motions through setting nut 8, thereby the console lift leaves,
The top of thru-bolt 2 is connected with winch support, and brake band breaks away from rolling mechanism under the winch operative scenario, and the spring 1 on the thru-bolt 2 is not stressed and can stretches; Drive connecting panel 6 and oppress roller 4 and move downward, roller 4 contacts brake hub downwards from the brake band opening part, lifting brake band 5; Whole brake band 5 just has only roller 4 to contact with wheel hub, belongs to friction of rolling, and contact surface is very little; Watt loss is very little, can ignore.
