Abstract
A floating normally open type brake comprises a base, an upper machine body and a lower machine body, wherein friction plate stop plates are mounted on the two sides of the upper machine body and the two sides of the lower machine body; a sliding shaft is arranged on the base; the lower and the upper machine bodies are connected to the sliding shaft; a lower friction plate is arranged on the lower machine body; the upper machine body is arranged above the lower machine body; a piston is mounted in the upper machine body; an upper friction plate is mounted on the front end surface of the piston in the upper machine body, and is connected to the upper machine body through a tightening screw; a guide shaft of a travel switch is connected with the upper machine body and an upper friction sheet; the travel switch is mounted on the upper machine body; a spring is mounted on the sliding shaft above the upper machine body; and a brake disc is arranged between the upper friction sheet and a lower friction sheet. The floating normally open type brake adopts the floating installation design and a normally open type hydraulic station to drive braking; moreover, the action is fast, safe and reliable.
Description
Technical field
The utility model belongs to supporting mechanical braking of Mechanical Driven or speed reducer, relates in particular to a kind of normal open-reel break that floats.
Background technique
Adopted disk type braker as braking device more and more in the mechanical device now, traditional fixed break and swing type break, brake clearance is big, the reaction time is long, sensitivity, structure more complicated, installation and maintenance are all very difficult inadequately in action, do not reach in the present mechanical device for the demand of break, influenced development of productivity.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of braking open in usual of floating, and is used for substituting traditional break.
In order to address the above problem by the following technical solutions: comprise base, on, lower body, on, the friction plate block all is equipped with in the lower body both sides, base is provided with slide-bar, lower body and upper machine body are connected on the slide-bar, lower body is provided with down friction plate, the lower body top is provided with upper machine body, piston is housed in the upper machine body, on the upper machine body inner carrier front-end face friction plate is housed, last friction plate is connected on the upper machine body by stretching screw, the position limit switch guide shaft is connecting upper machine body and upper friction plate, position limit switch is housed on the upper machine body, on the slide-bar of upper machine body top spring is housed, brake disc is arranged on, between the following friction plate.
Described slide-bar is fixed on the base by expansion pin, lower body and upper machine body are connected on the slide-bar by hex head bolt, following friction plate is connected on the lower body with stretching screw, the stretching screw spring is housed on the stretching screw, spring top on the slide-bar is provided with pressing plate, and pressing plate is connected on the slide-bar by socket head screw.
The utility model adopts the installation and design of floating, and Installation and Debugging are more faster, convenient with swing type than fixed; Adopt design hydraulic station open in usual to drive braking, be swift in motion, safe and reliable; Adopt high performance friction material, the good stable friction performance of heat resistance; Brake clearance is little, the reaction time is short, is swift in motion, and is simple in structure, installation, easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a left view of the present utility model.
Embodiment
As shown in the figure, a kind of break open in usual that floats, comprise base 1, slide-bar 6 is housed on the base 1, slide-bar 6 usefulness expansion pin 18 are fixing, lower body 2 all uses hex head bolt 4 to be connected on the slide-bar 6 with upper machine body 3, friction plate 14 is housed down on the lower body 2, following friction plate 14 usefulness stretching screws 17 are connected on the lower body 2, stretching screw spring 16 is housed on the stretching screw 17, friction plate block 15 is equipped with in lower body 2 both sides, upper machine body 3 is equipped with in lower body 2 tops, piston 8 is housed in the oil cylinder of upper machine body 3, friction plate 12 is housed on the piston 8, last friction plate 12 is connected on the upper machine body 3 by stretching screw 17, stretching screw spring 16 is housed on the stretching screw 17, the friction plate block is equipped with in the upper machine body both sides, position limit switch guide shaft 10 is connecting upper machine body 3 and last friction plate 12, position limit switch 9 is housed on the upper machine body 3, on the upper machine body 3 top slide-bars 6 spring 5 is housed, the pressing plate 7 usefulness socket head screws 11 of spring 5 tops are connected on the slide-bar 6, brake disc 13 is arranged between friction plate 12 and the following friction plate 14, when machinery shuts down, feeding hydraulic oil in the oil cylinder of upper machine body 3 makes piston 8 promotion friction plates 12 press to brake disc 13, last friction plate 12 clamps brake disc 13 with following friction plate 14, realizes braking, and machinery shuts down.When friction disc wear when the certain limit, the position limit switch guide shaft that is installed on upper machine body and the friction plate moves certain distance downwards, is contained in position limit switch place on the upper machine body when bumping less than the position limit switch guide shaft, the warning device that is connected on the position limit switch gives a warning.
