Abstract
A single-spring floating normally closed brake comprises a floating base, a main brake body and an auxiliary brake body. An oil cylinder is arranged on the main brake body, a rear cover is connected with the main brake body to form a cylinder body, both the main brake body and the auxiliary brake body are provided thereon with a friction disc, the outer end surface of the piston is tightly attached to the bottom plate surface of the friction disc of the main brake body, a sliding shaft is arranged on the floating base, the main brake body and the auxiliary brake body are connected together through bolts and mounted on the sliding shaft of the base, a spring lower base is arranged on the sliding shaft, a spring upper base is fixed at the top end of the sliding shaft through a spring compression screw, and a return spring is arranged between the spring upper base and the spring lower base of the sliding shaft. The single-spring floating normally closed brake, with small volume and compact structure, adopts a floating type installation design, resulting in more rapid and convenient installation and debugging, adopts a normally closed design, resulting in rapid action and safe and reliable performance, and adopts a linked reset design, resulting in uniform open interval of the brake and convenient adjustment.
Description
Technical field
The utility model relates generally to the unsteady disc type brake device of a kind of hydraulic pressure list spring, is mainly used in supporting mechanical braking and the deceleration of multiple Mechanical Driven that various industries such as reaching lifting transportation, harbour handling, cable, hoist cable equipment are gone up in the brake of wind power generating set high speed shaft.
Background technique
Raising along with science and technology development and Machine Design level, adopted disk type braker as braking device in the various mechanical devices more and more, because it is compared with traditional band brake, block brake and internal expanding shoe brake, it is steadily reliable to have braking, simple in structure, it is convenient to install, tie up the family, and disk type braker is along the brake disc axial force distribution, and brake axle is not subjected to moment of flexure, compact structure, size is little, detent torque range is big, and braking ability is stable, good heat dissipation, and can one the dish multimachine, a machine polydisc.Disk type braker has the function of its superior uniqueness just, is widely used in every field, and occupies sizable share, becomes the main developing direction that the first-selection on every profession and trade main frame and other Mechanical Driven equipment is braked control product and break.And the used disk type braker of present China, because piston can not automatically reset, opening a sluice gate the gap can not be constant, is installing also fixed and swing types that adopt more, it installs extremely inconvenience, has caused certain narrow limitation to installation.
Summary of the invention
The purpose of this utility model is to provide a kind of single spring floating type braking device, adopts floating type installation and design, and Installation and Debugging are quick, convenient; The interlock design that resets makes and opens a sluice gate the gap equalization
The technical solution of the utility model is that following mode realizes: comprise unsteady base, main brake body and secondary braking body, the main brake body is provided with oil cylinder, piston and piston rod are housed in the oil cylinder, the dish spring is housed on the piston rod, dust ring and sealing are housed between oil cylinder and the piston, bonnet and main brake body connect to form cylinder body, be provided with friction plate on main brake body and the secondary braking body, block is equipped with in the friction plate both sides, the friction plate base plate face of main brake body is close in the piston exterior edge face, unsteady base is provided with slide-bar, the main brake body is connected as one by bolt with secondary braking body, is contained on the slide-bar of base, and slide-bar is provided with spring lower seat, on the slide-bar top, reset spring is arranged on the spring of slide-bar by the spring compression screw at the spring seat of honour, on between the following seat.
Described slide-bar is fixed on the base that floats by expansion pin, and the main brake body connects as one on the slide-bar that is contained in the base that floats by bolt with secondary braking body, and described block is connected on the body by bolt.
The utility model volume is little, and compact structure adopts floating type installation and design, and Installation and Debugging are more faster, convenient with swing type than fixed; The design of employing Normally closed type, the belleville spring braking, hydraulic station drives and discharges, and is swift in motion, and is safe and reliable; Adopt the design that resets that links, break is opened a sluice gate the gap equalization, and is easy to adjust.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Embodiment
As Fig. 1, shown in Figure 2, a kind of single spring normally closed brake that floats, comprise the base 1 that floats, main brake body 10, secondary braking body 23, piston 15, dish spring 13, bonnet 14, slide-bar 7, reset spring 6, oil cylinder 16 is located on the main brake body 10, piston 15 and piston rod 12 are housed in the oil cylinder 16, piston 15 and piston rod 12 are welded as a whole, dish spring 13 is housed on the piston rod 12, between oil cylinder 16 and the piston 15 dust ring 20 is housed, sealing 17, sealing 19, bonnet 14 links together by outside thread and internal thread with main brake body 10 and forms a cover cylinder body, slide-bar 7 is fixed on the base 1 that floats by expansion pin 2, unsteady base is provided with slide-bar, main brake body 10 connects as one by bolt 24 with secondary braking body 23 and is contained on the slide-bar 7, slide-bar is provided with spring lower seat 5, the spring seat of honour 8 is fixed on the slide-bar top by spring compression screw 9, reset spring 6 is arranged on the spring of slide-bar, on between the following seat, reset spring 6 is contained on the slide-bar 7 that main brake body 10 and secondary braking body 23 adorned, and wherein slide-bar 7, the spring seat of honour 8, spring lower seat 5, reset spring 6 is formed the interlock resetting means.
Two blocks 4 all are equipped with in main brake body 10 and secondary braking body 23 both sides, block 4 is connected on the body by bolt 3, the following friction plate of the upper friction plate of main brake body 10 and secondary braking body 23 all is arranged on two block inboards, upper friction plate base plate face is close in piston 15 exterior edge faces, all being equipped with between friction plate return spring 25 and friction plate return screw 26, two friction plates 21 on the upper and lower friction plate 21 is brake disc 22.
Working principle: not when hydraulic fluid port 18 fuel feeding are pressed, the dish spring promotes piston by elastic force and moves to brake disc 22 directions, and break is in braking state.Behind the fuel feeding, under the effect of oil pressure, oil pressure promotes piston 15 and moves backward, and friction piece 21 departs from brake disc through the rebounding force drawing friction body of friction piece return spring 25, thereby removes braking state.
When main brake body and secondary braking body connect as one by bolt, on slide-bar, float, reset spring can make its break return, thereby guarantees that break opens a sluice gate the gap equalization, and easy to adjust.
