Background technique
The coupling kind is a lot, but can provide the coupling of over-torsion protection function few.In mechanical transmission, adopt general coupling not export by control torque,, just require to add detection in actuating station if want to protect the part of output terminal.The possibility working position is a lot of on the one hand in the detection of actuating station, needs a lot of Check points, increases cost, and also possible on the other hand detection difficulty is bigger.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned shortcoming that overcomes prior art, and a kind of coupling that has over-torsion protection function reliably is provided.
The present invention realizes with following technological scheme: a kind of coupling with over-torsion protection function comprises: line shaft, bearing axle, upper clutch block that is connected with line shaft and the lower clutch block that is connected with bearing axle; It is characterized in that; Also comprise many stage clips driving upper and lower clutch block and open or close, with upper clutch block close and can control line shaft work or stop near switch.
Described lower clutch block is fixed on the bearing axle by key and nut, and the upper end of lower clutch block is uniform to be provided with many clutch pawls; Described bearing axle upper end is provided with adjusts nut and pressure pad, and the three is connected and fixed by screw.
Described upper clutch block is the tubular body that cylindrical has a plurality of steps, and the lower end is uniform to be provided with many clutch pawls, and the endoporus sliding fit of upper clutch block is sleeved on bearing axle top, and the top of upper clutch block cylindrical is inserted in the hole of connecting sleeve by the feather key sliding fit; Described connecting sleeve top is connected and fixed by coupling and line shaft; Make the flange that goes in ring on the cylindrical of upper clutch block bottom, be installed in the position of the approaching flange that goes in ring on the lathe near switch.
Many stage clips are set between described connecting sleeve and the upper clutch block, and described stage clip upper end is provided with adjusting screw, spring pressuring plate and locking nut.
Described clutch pawl is an eccentric circular ring, and the section of eccentric circular ring is a rectangle; Two groups of clutch pawls on described upper clutch block and the lower clutch block are when coupling is worked, and an end that is in contact with one another is made into the slope shape helicoid.
Described coupling is the ringfeder coupling.
Good effect of the present invention is; During proper functioning, upper clutch block is delivered to lower clutch block to moment of torsion by upper and lower clutch block helicoid, bearing axle work.Work as device fails, the bearing axle resistance increases suddenly, and when surpassing rated torque T, upper clutch block rises along helicoid, and upper and lower clutch pawl breaks away from mutually; Simultaneously, the belt flange on the upper clutch block cylindrical departs near switch, sends signal near switch, system alarm and parking.Safety, reliable, damage machinery when avoiding transshipping.

Embodiment
As shown in Figure 1: a kind of coupling with over-torsion protection function comprises: line shaft 1, bearing axle 9, upper clutch block 11 that is connected with line shaft 1 and the lower clutch block 8 that is connected with bearing axle 9; It is characterized in that; Also comprise: drive upper and lower clutch block 11,8 foldings many stage clips 7, with upper clutch block 11 near and can control line shaft 1 work or stop near switch 6.
Described lower clutch block 8 is fixed on the bearing axle 9 by key 17 and nut 10, and the upper end of lower clutch block 8 is uniform to be provided with many clutch pawls 16; Described bearing axle 9 upper ends are provided with adjusts nut 5 and pressure pad 4, and the three is connected and fixed by screw 15.
Described upper clutch block 11 has the tubular body of a plurality of steps for cylindrical, the lower end is uniform to be provided with many clutch pawls 16, the endoporus sliding fit of upper clutch block 11 is sleeved on bearing axle 9 tops, and the top of upper clutch block 11 cylindricals is inserted in the hole of connecting sleeve 3 by feather key 14 sliding fits; Described connecting sleeve 3 tops are connected and fixed by coupling 2 and line shaft 1; Make the flange 18 that goes in ring on the cylindrical of upper clutch block 11 bottoms, be installed in the position of the approaching flange 18 that goes in ring on the lathe near switch 6.
Between described connecting sleeve 3 and the upper clutch block 11 many stage clips 7 are set, described stage clip 7 upper ends are provided with adjusting screw 13, spring pressuring plate 12 and locking nut 19.
Described clutch pawl 16 is an eccentric circular ring, and its section is a rectangle; Two groups of clutch pawls 16 on described upper clutch block 11 and the lower clutch block 8, a contacted end is made into slope shape helicoid 16-1 when coupling is worked.
In an embodiment, described coupling 2 has adopted the ringfeder coupling.Line shaft 1 end is porose, holds the screw head of long spiro nail 15.
In an embodiment, also be provided with locking nut 19 on the described adjusting screw 13, be used to adjust stage clip 7 back locking joint screws 13, prevent to become flexible.
