Description
Technical field
The utility model belongs to mechanical field, relates to free wheel device, especially a kind of two braking free wheel devicees of idle running.
Background technique
Clutch is mechanical field vitals, and kind is more.Free wheel device is a kind of clutch adopting roller to surmount locking mode braking, at present, is mostly single brake coupling and two brake coupling.Overrunning clutch is that in adopting, shifting block drives outer ring or outer ring to drive inner ring shifting block one direction to rotate and idle running; Twin-direction clutch is then drive outer ring or outer ring to drive interior shifting block to two sideway swivels by interior shifting block, does not have the function dallied.Because clutch is application component, in some occasions, needs can realize idle running, to realize some specific functions.But the structure of existing clutch cannot realize idle running, limits the application area of clutch.
By patent retrieval, not yet find the patent document relevant to the utility model.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of two braking free wheel devicees of idle running.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of two braking free wheel devicees of idle running, comprise external toothing, brake disc, interior shifting block, locking post, spring and cover plate, outer shifting block, coaxially brake disc is installed in external toothing, coaxially cover plate is installed on the disc brake rotor, on cover plate and brake disc, all correspondence is shaped with the identical axis hole of the axis hole made with external toothing, brake disc bilateral symmetry is shaped with a braking conduit, shifting block in middle part setting-in between each braking conduit and external toothing, in each in each braking conduit, a locking post is all installed between shifting block and the brake disc of both sides, locking post in braking conduit and the brake disc between brake disc are fixedly mounted with a spring, cover plate is also shaped with an arc-shaped window in shifting block position in correspondence, the bilateral symmetry of this arc-shaped window is shaped with idle running pit and braking pit, outer shifting block outside interior shifting block and cover plate is fixedly mounted with by fastening screw trip bolt, and the fastening screw trip bolt both sides positional symmetry of shifting block respectively engages installation one and locates adjustment screw outside.
And the structure of described location adjustment screw is: be provided with a stage clip below the location adjustment screw outside in shifting block, coaxially install a detent ball in the outer shifting block below this stage clip.
Advantage of the present utility model and beneficial effect are:
1, this clutch is on the basis of two brake coupling, is provided with an idle running gear, brake disc and interior shifting block are combined between the braking of both sides, make interior shifting block while the braking of both sides, achieve lost motion functionality, reduce volume simultaneously, meet the demand of specific use.
2, this clutch configuration science, novel ingenious, compact, can meet the bar stroke in the two brake coupling of machinery industry, be with a wide range of applications and use value.

Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of two braking free wheel devicees of idle running, comprise external toothing 1, brake disc 5, interior shifting block 2, locking post 4, spring 6 and cover plate 11, outer shifting block 13, coaxially brake disc is installed in external toothing, screw 12 is adopted coaxially cover plate to be installed by screw hole 8 on the disc brake rotor, on cover plate and brake disc, all correspondence is shaped with the identical axis hole of the axis hole 7 made with external toothing, brake disc bilateral symmetry is shaped with a braking conduit, shifting block in middle part setting-in between each braking conduit and external toothing, in each in each braking conduit, a locking post is all installed between shifting block and the brake disc of both sides, locking post in braking conduit and the brake disc between brake disc are fixedly mounted with a spring, cover plate is also shaped with an arc-shaped window in shifting block position in correspondence, and the bilateral symmetry of this arc-shaped window is shaped with idle running pit 9 and braking pit 10, and interior shifting block is shaped with outer shifting block screw hole 3, outer shifting block outside cover plate is adopted by fastening screw trip bolt 15 and is fixedly mounted with outer shifting block screw hole engagement system and interior shifting block, the fastening screw trip bolt both sides positional symmetry of shifting block respectively engages installation one and locates adjustment screw 14 outside, the structure of this location adjustment screw is see Fig. 5, below location adjustment screw outside in shifting block, a stage clip 16 is installed, coaxial installation one detent ball 17 in the outer shifting block below this stage clip.
Working principle of the present utility model is:
As required, when being stirred to the left and right sides by outer shifting block and make ball be positioned at two braking pits, interior shifting block promotes locking post displacement to the left and right sides and is locked between brake disc and external toothing to realize braking; When needs dally, outer shifting block is positioned at idle running groove position, now two locking posts brake off under the promotion of spring, realizes idle running thus.
