Description
Technical field
The utility model belongs to hydraulic motor technical field, more particularly to a kind of disc spring type hydraulic motor brake
Structure.
Background technology
At this stage, axial-piston hydraulic motor designing technique is gradually maturation, is integrated with internal self-sustaining gear mostly,
Its core component is made up of brake hoop, brake(-holder) block, sealing ring and compression cylindrically coiled spring etc..The braking side of this form
Formula need to bore milling flat-bottom hole in tripping spring both ends mounting surface or one end mounting surface ensure the installation of cylindrical spring, work it is steady
It is qualitative.Because cylindrical spring elastic deformation is big, appearance and size is also relatively large, therefore what is needed uses space larger, in general
In axial piston motor design, also easily reach space requirement but in the special piston motor of Miniature plunger motor and part
In, due to arrestment mechanism design space deficiency, typically it is not provided with arrestment mechanism or arrestment mechanism is arranged on outside piston motor.
Such design can not meet the design requirement of overall machinery.
The content of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of disc spring type hydraulic motor system
Motivation structure.
To achieve the above object, the utility model uses following technical proposals：A kind of disc spring type hydraulic motor arrestment mechanism,
Including brake hoop, brake(-holder) block, sealing ring, back-up ring and butterfly spring, the brake hoop is located at cylinder body top, valve body side, shell
Below body, described brake hoop one end and valve body form annular groove, and the brake hoop other end connects region with shell body, cylinder body
Provided with uniform longitudinal fluting, closed piston oil pocket is formed with shell body above the brake hoop；It is provided with the annular groove
Dish-style spring, the closed piston oil pocket both sides are provided with the sealing ring and back-up ring of step distribution along brake hoop circumference, described
Brake(-holder) block is provided with longitudinal fluting.
The beneficial effects of the utility model are：Disc spring type hydraulic motor arrestment mechanism of the present utility model is to space requirement
Low, stroke is short, and bearing load is big, easy to use, and assembled scheme is more, and it is easy that maintenance is changed, safe, service life length,
It is economical and practical, especially in the special piston motor design of Miniature plunger motor and part, can fundamentally solve arrestment mechanism
The problem of design.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is cross-sectional view of the present utility model；
Fig. 2 is part sectioned view.
Shown in figure：1st, valve body, 2, butterfly spring, 3, back-up ring, 4, sealing ring, 5, sealing piston oil pocket, 6, brake hoop, 7,
Shell body, 8, brake(-holder) block, 9, cylinder body.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
A kind of disc spring type hydraulic motor arrestment mechanism as shown in Figure 1, including brake hoop 6, brake(-holder) block 8, sealing ring 4, gear
Circle 3 and butterfly spring 2, the brake hoop 8 are located at the top of cylinder body 9, the side of valve body 1, the lower section of shell body 7, described one end of brake hoop 6
Annular groove is formed with valve body 1, and the other end of brake hoop 6 region that connects with shell body 7, cylinder body 9 is recessed provided with uniform longitudinal direction
Groove, the top of brake hoop 6 form closed piston oil pocket 5 with shell body 7；Dish-style spring 2 is provided with the annular groove, it is described
The both sides of closed piston oil pocket 5 are provided with the sealing ring 4 and back-up ring 3 of step distribution along the circumference of brake hoop 6, in the longitudinal fluting
Provided with brake(-holder) block 8.
In running, pressure oil is supplied by valve body 1, by the braking oil duct of shell body 7, reached by brake hoop 6 and shell body 7
Between sealing piston oil pocket 5, the sealing ring 4 and back-up ring 3 at both ends seal, and depended on pressure jacks up brake hoop 6, overcomes butterfly spring
2 elastic force, loosen the space of brake(-holder) block 8, reach the purpose for releasing braking.When motor fuel cut-off, the elastic force of butterfly spring 2 passes
Brake hoop 6, the compression seal oil pocket 5 of brake hoop 6 are passed, hydraulic oil is returned by crude oil road, and brake hoop 6 compresses brake(-holder) block 8, motor quilt
Braking.
Preferred embodiment of the present utility model is the foregoing is only, not limiting the utility model, all book
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
