By the disc brake, the braking failure of a brake due to rapid abrasion of a single-side friction sheet can be effectively prevented, the potential safety hazard problem existing in the prior art is solved, and the safety performance of the brake is improved; and the disc brake has a simple structure and low installation and manufacturing cost, can be reformed on the basis of the conventional disc brake, and is suitable to be popularized and applied in industries such as hoisting, transportation, metallurgy, mines, machinery, chemical engineering, ports and the like which use the disc brake.
Description
Technical field
The invention belongs to the braking field of mechanical technique, definite saying relates to a kind of disk type braker.
Background technique
Friction plate on two brake arms of existing disk type braker and the position between the brake disc are fixed, and the normal clearance between two friction plates and the brake disc generally is no more than 1mm.Temperature can raise behind the equipment long-play, thereby can cause the coupling that links to each other with brake disc, the meeting such as reductor shaft axial elongation, drive brake disc and produce axial displacement, when serious, the axial internal clearance of brake disc can reach 3mm, much larger than the normal clearance between friction plate and the brake disc, the brake disc of High Rotation Speed and wherein a side friction plate gap are increased and the friction plate of opposite side is lived in inflexibly compressing, cause the temperature of brake disc and friction plate to raise rapidly, with the friction plate rapid wearing of brake disc friction, brake performance descends, and causes brake failure when serious, there is serious potential safety hazard, causes easily serious security incident.
Summary of the invention
The objective of the invention is: provide a kind of disk type braker of auto-compensation axial deviation of brake disc, to solve the problem that causes easily braking failure in the prior art because of brake disc axial displacement.
Technological scheme of the present invention is: a kind of disk type braker of auto-compensation axial deviation of brake disc, comprise base and the movable relatively brake arm of cooperation of two on the base that is assemblied in, the bottom of described two brake arms is relative being hinged on a connecting seat respectively, this connecting base connects and composes parallel four-bar linkage by at least two connecting rods that be arranged in parallel and base, and an articulating point in parallel four-bar linkage is provided with the frictional damping mechanism that rotates for connecting rod corresponding to restriction at least.
One end of described two parallel linkage respectively corresponding the rotation is assemblied on the hinged hinge axis of two brake arms and connecting plate, its other end respectively with base on the connection bearing of corresponding setting hinged.
Described two connect and to end respectively spinning on the bearings and be furnished with for the bearing pin hinged with respective link, and described frictional damping mechanism is the expansion sleeve that is arranged between two parallel linkage and the corresponding bearing pin.
Described each bearing pin ends spinning by the bolt that radially is located in its end and cooperate with the base block respectively and joins.
The present invention by and hinged connecting plate, the base of two brake arms and be connected to connecting plate and base between the parallel four-bar linkage that consists of of two connecting rods so that when the axial displacement of brake disc generation, two brake arms can automatically be followed brake disc and be moved axially, thereby effectively prevented the problem of the break braking failure that the rapid wearing because of one-sided friction plate causes, solve the potential safety hazard that exists in the prior art, improved the Safety performance of break; And it is simple in structure, can transform on the basis of existing disk type braker, and installation, low cost of manufacture are suitable for applying in the industry of the use disk type brakers such as lifting, transportation, metallurgy, mine, machinery, chemical industry, harbour.
Description of drawings
Fig. 1 is the structural representation of the disk type braker specific embodiment of auto-compensation axial deviation of brake disc of the present invention.
Embodiment
The specific embodiment of the disk type braker of auto-compensation axial deviation of brake disc of the present invention as shown in Figure 1, this disk type braker mainly by be movably connected on the base 3 about two brake arms 1,2 and the driving mechanism 18 that is in transmission connection in two link arms upper ends form, be respectively equipped with the friction plate that cooperates with brake disc 17 at two brake arms 1,2.Two brake arms 1,2 lower end are hinged on respectively on a plate 16, wherein, left brake arm 1 is hinged with connecting plate 16 by left hinge axis 4, be hinged with left connecting rod 5 at left hinge axis 4, the other end of left connecting rod 5 rotates assembling by the left bearing pin 8 that arranges on the left connection bearing 6 of corresponding setting on left expansion sleeve 7 and the base 13, radially is equipped with to cooperate with base 3 blocks to prevent that left bearing pin 8 from rotating only revolves bolt 9 on left bearing pin 8; Right brake arm 2 is hinged with connecting plate 16 by right hinge axis 10, be hinged with right connecting rod 11 at right hinge axis 10, the other end of right connecting rod 11 rotates assembling by the right bearing pin 14 that arranges on the right connection bearing 12 of corresponding setting on right expansion sleeve 13 and the base 16, radially is equipped with on the right bearing pin 14 to cooperate with base 3 blocks to prevent that right bearing pin 14 from rotating only revolves bolt 15; Enough become parallel four-bar linkage by left connecting rod 5 and right connecting rod 11 between connecting plate 16 and the base 3.
Among the present invention, about two connecting rods 5,11 with corresponding bearing pin between the expansion sleeve installed adopt existing Z2 type expansion sleeve, can adjust the size of the friction damping force between two connecting rods and the corresponding bearing pin by adjusting adjusting bolt on the expansion sleeve, to limit freely rotating of parallel four-bar linkage.In actual applications, this expansion sleeve can also adopt friction sleeve, friction ring or the friction plate of other structure or shape to realize that this all those skilled in the art will readily appreciate that, all within protection scope of the present invention.
Working principle of the present invention is: when brake disc 17 produces axial displacement because of reasons such as temperature variation, brake disc 17 reduces and increases with opposite side brake arm gap with the gap of a side brake arm wherein, when break is braked, two brake arms are stressed inwardly to be closed up, because the displacement of two brake arms is identical, therefore the less brake arm in gap at first contacts brake disc, this brake arm overcomes expansion sleeve in top compacting Moving plate friction damping force offsets to one side parallel four-bar linkage, thereby larger brake arm top, gap is pressed on the brake disc; When break is opened again, two brake arms outwards open and reset simultaneously, and parallel four-bar linkage can't rotate owing to the damping force effect of expansion sleeve, thereby remain on shift state, so that the gap of the relative brake disc of two brake arms reaches unanimity again, until braking distance begins next time.Thereby avoided one-sided friction plate eccentric wear to occur, guaranteed break validity and Security.
