The invention discloses a connecting device which comprises a driving shaft, a driven shaft, a back tightening nut, a main shaft nut arranged on the driving shaft, a fixing block arranged on the driving shaft and a safety nut arranged on the driven shaft. The driving shaft is provided with an internal thread hole, the driving shaft and the driven shaft are in sleeved connection, and the driving shaft and the driven shaft are provided with an internal thread and an external thread which are meshed with each other. The safety nut is provided with a synchronous screw rod, and the safety nut is connected with the main shaft nut through the synchronous screw rod. A safety screw is further arranged on the safety nut, and the safety screw penetrates through the safety nut and is connected with the fixing block. The back tightening nut is mounted on the synchronous screw rod and is placed on the left side of the safety nut. The connecting device is simple in structure, convenient to use and mount, easy to operate, firm in connection, convenient to disassemble, low in cost, convenient to transport, high in bearing strength, reliable in prevention effect, wide in application range, long in service life, safe and reliable.
Description
Technical field
The present invention relates to a kind of connection set.
Background technique
In fin tube rolling equipment, cutter shaft is connected the normal bolt and nut that adopts and tightly completes connection with standby with transmission shaft, because moment of torsion in the operation of rolling is very large, can cause screw mandrel and nut for tight tension, in the time that needs are dismantled, is difficult to loosening standby mother, time-consuming taking a lot of work; And in the operation of rolling, cutter hub needs folding, between cutter shaft and transmission shaft, need axial stretching with compensating axial displacement, but the transmission shaft being connected by bolt and nut can not be realized nose balance.Therefore need a kind of rational in infrastructure, connection cutter shaft of reliable in function and the device of transmission shaft.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in structure, uses, easy for installation, simple to operate, be connected firmly, and convenient disassembly, cost is low, and convenient transportation is applied widely, and long service life has the connection set of safe and reliable effect.
For addressing the above problem, the present invention adopts following technological scheme:
A kind of connection set, comprise driving shaft, driven shaft and back tightening nut, and be arranged on the mainshaft nut on driving shaft, and be arranged on the fixed block on driving shaft, and be arranged on the jam nut on driven shaft, described driving shaft is provided with interior threaded hole, described driving shaft and driven shaft socket, described driving shaft and driven shaft are provided with intermeshing internal thread and outside thread, described jam nut is provided with synchronous screw rod, described jam nut is connected with mainshaft nut by synchronous screw rod, on described jam nut, be also provided with safety screw, described safety screw runs through jam nut, and be connected with fixed block, described back tightening nut is arranged on synchronous screw rod, and be positioned at the left side of jam nut.
As preferred technological scheme, the distance between described jam nut and mainshaft nut is 30-70mm, and described synchronous screw rod and safety screw are equipped with six.
As preferred technological scheme, described internal thread is arranged in driving shaft, and described outside thread is arranged on driven shaft.
As preferred technological scheme, on described driven shaft, be provided with spline with the driving shaft place of matching, described spline is provided with two.
The beneficial effect of a kind of connection set of the present invention is: when use, on driven shaft, increase a jam nut, six synchronous screw rods are installed on jam nut, on feed screw nut, manufacture six synchronous holes, six synchronous screw rods on jam nut are arranged in synchronous hole, large 2～6 millimeters than key-bolt diameter of synchronous bore dias, spacing between jam nut and screw mandrel spiral shell is wanted suitably, spacing general control is at 30-70mm, when installation, with the tight synchronous screw rod of the back tightening nut back of the body, in case synchronous screw bolt loosening, by the safety screw of setting up, can play double locking preventive effect with jam nut.It is simple in structure, and use, easy for installation, simple to operate, is connected firmly, convenient disassembly, and cost is low, convenient transportation, bearing strength is high, and preventive effect is reliable, applied widely, and long service life has safe and reliable effect.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of connection set of the present invention.
