Abstract
The utility model relates to a brake, in particular to a decompression brake, which is characterized in that both ends of an outer housing are respectively connected with an end cover and a flange in a sealing mode. The central portion of the end cover is provided with a through hole which is communicated with the hollow cavity of the central portion of the housing body, and the inner wall of the front half portion of the housing body is provided with a spline which is respectively connected with an external tooth friction wafer (2) and an internal tooth friction wafer (1). A gap is arranged between the external tooth friction wafer (2) and the internal tooth friction wafer (1) which is connected with a power source, and the rear half portion of the housing body forms a ring oil cylinder (5) between the outer housing (10) and a ring piston (6). The circumference of the ring piston (6) is provided with a high-intensity spring (7), and the housing body is provided with an oil inlet screw and a blow-off screw plug. The decompression brake has small size, large braking moment and compact structure; the dust decompression brake does not generate pollution for the inner portion of a machine, and the size of the braking moment can be adjusted.
Description
Technical field: the utility model relates to break, more specifically to be the decompression break.
Background technique: known decompression break volume is big, is Open architecture, and inner easily generation of lead aircraft device service time one polluted.It adopts the wearing and tearing of belleville spring friction plate bigger to its Safety Effect, and braking moment is unadjustable.
Summary of the invention: the purpose of this utility model provides a kind of decompression break, and its volume is little, the braking square is big, compact structure, machine intimate is not produced pollution; Braking moment can regulate size.
The technical solution of the utility model is: design a kind of decompression break, it is characterized in that: the shell two ends are sealedly connected with end cap respectively and connect dish, the end cap central part has through hole, through hole is connected with the cavity of housing central part, on housing first half inwall, there is spline to be connected with external tooth friction plate 2 and internal toothed friction plate 1 respectively, gapped between external tooth friction plate 2 and the internal toothed friction plate 1, internal toothed friction plate 1 is connected with power source; Latter half of, between shell 10 and annular piston 6, formed an annular cylinder 5, at annular piston 6 peripheries high-strength spring 7 is arranged, the resistance of oil-feed screw and blowdown spiral shell is arranged on the housing.
Described friction plate is inside and outside multiple tooth structure.
Described housing 10 profiles are the garden cylindricality.
Described spring is a helical spring.
Described oil cylinder is the staggered form structure.
The utility model compared with prior art has following advantage:
1, volume is little, the braking square is big.
2, compact structure, novelty, hermetically sealed, machine intimate is not produced pollution.
3, structure has variability and expansivity.
Description of drawings: the utility model is described further below in conjunction with embodiment's accompanying drawing.
Fig. 1: decompression brake structural schematic representation.
Among the figure: 1, internal toothed friction plate; 2, external tooth friction plate; 3, connect dish; 4, oil-feed screw; 5, annular cylinder; 6, annular piston; 7, high-strength spring; 8, end cap; 9, blowdown spiral shell resistance; 10, housing.
Embodiment: the decompression break, housing 10 profiles are cylindrical as shown in Figure 1.Connecing dish 3 connects with end cap 8 with housing 10.Two partly formed before and after inner chamber divided: housing 10 first halfs are equipped with external tooth friction plate 2 and internal toothed friction plate 1 respectively in the middle of housing 10 inwall splines, they leave certain clearance each other, and internal toothed friction plate 1 is connected with outside power source such as motor.Formed an annular cylinder 5 between latter half of housing 10 and the annular piston 6, the high-strength spring 7,4 that some is housed at annular piston 6 peripheries is the oil-feed screw, and 9 are the resistance of blowdown spiral shell.
Pressure oil in the hydraulic system enters annular cylinder 5 by oil-feed screw 4, annular piston 6 is under the effect of oil pressure all the time steps back the position such as Fig. 1 shows situation, 1 rotation of driven by motor internal toothed friction plate, do not have any drag effects, when circuit has a power failure suddenly, oil pump is stall also, oil pressure drops to zero, annular piston 6 has lost the promotion of oil pressure, this moment, all high-strength springs 7 promoted annular piston 6, compressed internal toothed friction plate 1 and external tooth friction plate 2, thereby had stoped the rotation of motor, with motor shaft locking tightly, reach the braking action of transmission system.When oil pump recovery proper functioning, annular cylinder 5 is full of pressure oil, and internal toothed friction plate 1 and external tooth friction plate 2 are unclamped, and motor also can proper functioning.Friction plate is respectively inside and outside multiple tooth structure; Oil cylinder is the staggered form structure; The brute spring that has been covered with sufficient amount on piston body, several parts connect with the high-strength bolt of sufficient amount.Make full use of the space of inner chamber.The axis realized of rear end cover being made hollow connects; Friction plate group number and number of springs can increase according to the requirement of braking moment or reduce.With spline structure can be greatly, can be little, can form series product.Friction plate is owing to be inside and outside multiple tooth structure, and friction plate can freely move forward and backward, and the group number of friction can increase, reduce, and the braking moment of Chan Shenging is changeable like this.The rear end cover area is bigger, and the quantity of putting spring can be more, so impacting force can be regulated.Since adopt helical spring pressure insensitive to the wearing and tearing of friction plate, safer than belleville spring.
