Description
Technical field
This utility model relates to mechanical equipment technical field, particularly relates to a kind of flexible coupling.
Background technology
Operation roll of mill road, because there is the aspect reason such as impulsive force, layout, is used Hooks coupling universal coupling, is connected by flexible coupling between Hooks coupling universal coupling with reducing motor, thus reduces the impact impact on reducing motor.See Fig. 2, Fig. 3, in prior art, universal drive shaft 8 is connected with the half a coupler B2 of flexible coupling by bolt 9, half a coupler B2 connects half a coupler A7 by bolt 5, vulcanie 12, axle head gland 13, and the half a coupler A7 of flexible coupling connects speed reducer output shaft set 11 by bolt 10 again.
Operationally, electric machine rotation, drive reductor, flexible coupling, universal drive shaft (telescopic) to rotate, finally drive roller bed rotation.In this process, the rotary inertia of universal drive shaft itself is very big, is telescopic because of universal drive shaft simultaneously, and this is as unsettled, so connecting shaft exists the trend shortened.So, universal drive shaft 8 gives mono-external pulling force of half a coupler B2 of flexible coupling, makes the connecting bolt 5 between half a coupler B2 and half a coupler A7 bear pulling force, and along with being continually changing of motor speed, this external pulling force changes the most at any time.Bolt 5 is under the effect of long-time variable force, and itself screw thread (M12) reaches fatigue limit, damages.Simultaneously as bolt 5 is inside the connection of universal drive shaft and flexible coupling, it is impossible to found by effective spot check, make hidden danger uncontrollable, causing flexible coupling to decompose and damage, accident occurs.
Summary of the invention
The purpose of this utility model is to provide a kind of flexible coupling, the flexible coupling in order to solve causing after flexible coupling connecting bolt loosens disconnects the problem damaged, and effectively prevents universal drive shaft from occurring with reducing motor disengagement accident, it is to avoid production accident.
For achieving the above object, this utility model realizes by the following technical solutions:
A kind of flexible coupling, including half a coupler A, half a coupler B, shaft coupling outer housing, half a coupler A is bolted with half a coupler B；Half a coupler A and speed reducer output shaft set are integrated setting, the periphery of half a coupler A is set to flange plate structure, the periphery of shaft coupling outer housing is also configured as flange plate structure, shaft coupling outer housing is pressed in the outside of half a coupler B and is connected with half a coupler A locking by bolt of long stem, is provided with ball between shaft coupling outer housing and half a coupler B.
Compared with prior art, the beneficial effects of the utility model are:
A kind of flexible coupling, half a coupler A is connected as a single entity with speed reducer output shaft set, simultaneously on the basis of original bolt fastening structure, flexible coupling adds again flange connection, constitute dual connection, thus it is weak to solve flexible coupling connecting bolt, cause the technical barrier that flexible coupling disconnection damages, effectively prevent universal drive shaft and the reducing motor disengagement accident from occurring, it is to avoid production accident.It addition, the flange connection increased is easy to closing, assembly and disassembly is convenient.

Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in detail, it should be noted that enforcement of the present utility model is not limited to following embodiment.
As it is shown in figure 1, a kind of flexible coupling, including half a coupler A1, half a coupler B2, shaft coupling outer housing 3, half a coupler A1 and half a coupler B2 is connected by bolt 5；Half a coupler A1 is integrated setting with speed reducer output shaft set 11, the periphery of half a coupler A1 is set to flange plate structure, the periphery of shaft coupling outer housing 3 is also configured as flange plate structure, shaft coupling outer housing 3 is pressed in the outside of half a coupler B2, it is connected with half a coupler A1 locking by bolt of long stem 4, ball 14, the most uniform setting of ball 14 it is provided with between shaft coupling outer housing 3 and half a coupler B2.
Half a coupler A1 passes through bolt 5 lock shaft side pressure lid 13, and axle head gland 13 compresses vulcanie 12 and half a coupler B2, it is achieved the connection of half a coupler A1 and half a coupler B2.Half a coupler A1 is by speed reducer output shaft set 11 connection speed reducer output shaft, half a coupler B2 is linked together with universal drive shaft 8 (telescopic) by bolt 9, the other end of universal drive shaft 8 is connected with roller-way, forms the drive connection of motor-speed reducer-flexible coupling-universal drive shaft (telescopic)-roller-way.
See that Fig. 2, shaft coupling outer housing 6 of the prior art are bolted on half a coupler B2, simply play the effect of protection.And the periphery of shaft coupling outer housing 3 with half a coupler A1 is both configured to flange plate structure (see Fig. 1) by this utility model; the two is connected by bolt of long stem 4 locking; while shaft coupling outer housing 3 is played a protective role, also play the effect of dual connection for flexible coupling.The most in the course of the work, the external tension distribution that universal drive shaft 8 produces, on bolt of long stem 4, by the daily spot check to bolt of long stem 4, can effectively find the loosening problem of bolt 4, so can find accident potential in time, it is simple to safeguard.
Owing to half a coupler A1, half a coupler B2 are compressed combination connected by bolt 5, axle head gland 13, vulcanie 12, it is nonrigid material because of axle head gland 13 and vulcanie 12 again, therefore half a coupler A1, half a coupler B2 are in the course of the work, can exist and relatively rotate.The flexible coupling improved, because the handle of flange plate structure is made a concerted effort big, is caused frictional force between half a coupler B2 and shaft coupling outer housing 3 big, makes operation torque will be transmitted by bolt of long stem 4, cause bolt of long stem 4 to there is fracture probability.Therefore, ball 14 is set between half a coupler B2 and shaft coupling outer housing 3, rolling by ball 14, reduce the frictional force between half a coupler B2 and shaft coupling outer housing 3, bolt of long stem 4 is solely subjected to pulling force and less circumferencial direction power, make operation torque by the transmission of original design path, thus eliminate the probability of bolt of long stem 4 fracture.
