Abstract
The utility model relates to a friction type driving shaft coupling device, which is characterized in that the utility model is provided with a coupling. The end of the coupling is processed a cylinder groove, the cavity of the groove is provided with a shaft joint body having the coaxial line with the coupling, and is provided with two semicircular tension blocks making the shaft joint body as the shaft center. The exterior margin of the tension block binds a friction disk, and the block body of the contact end of the two tension blocks is processed a countersunk. The countersunk is provided with a compression spring, and the shaft joint body and the tension blocks are connected by a pin key. The utility model can prevent the occurrence of the phenomenon of striking the gear wheels or twisting off the shaft.
Description
Affiliated technical field
The utility model relates to a kind of actuating unit field of machinery, the friction type transmission shaft coupling device between especially a kind of gearbox and the motor.
Background technique
At present, the transmission of known gearbox is by the coupling on the motor main shaft power to be passed to coupling on the I axle spindle nose in the gearbox, and the Fraquent start of motor produces gear in the gearbox or axle (as the C616 lathe) to clash and easily causes beating gear or axle is twisted off.In addition, sometimes need positive and negative car operation in operation, during especially positive and negative car alternately operating, fierce back and forth bump gear or axle and cause beating the generation of tooth or off-axis phenomenon, and all need when breaking down gearbox integral body is removed under lathe at every turn, decompose, clean, check, change new axle or new gear then.
Summary of the invention
In order to overcome the technical deficiency that existing transmission shaft coupling device is in use easily played gear and twisted off transmission shaft, the utility model provides the friction type transmission shaft coupling device, this the friction type transmission shaft coupling device not only can be avoided smashing gear in transmission or twist off the phenomenon generation of axle, and simple in structure, stable drive.
The technological scheme that its technical problem that solves the utility model adopts is: be provided with coupling, the coupling end is processed with cylinder shape groove, the groove inner chamber is provided with the shaft coupling body with the coupling coaxial line, the inner chamber of groove is that the axle center is equipped with two semicircle tightening pieces with the shaft coupling body, the outer rim of tightening piece is bonded with wearing piece, be processed with counterbore on the block of two tightening piece contact jaws, pressure spring is installed in the counterbore.Be connected by pin key between shaft coupling body and the tightening piece.
The beneficial effects of the utility model are, impact force obtains buffering under the effect of pressure spring and tightening piece and wearing piece when electric motor starting, friction by wearing piece drives I axle forward or reverse, takes place thereby can prevent the phenomenon of beating tooth or twisting off rotating shaft, and simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure cut-away view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
1. coupling among the figure, 2. wearing piece, 3. tightening piece, 4. pressure spring, 5. shaft coupling body.
Embodiment
In Fig. 1, one end of coupling 1 is processed with cylinder shape groove, cylinder shape groove is inner to be equipped with shaft coupling body 5 with coupling 1 coaxial line, the inner chamber of groove is that the axle center is equipped with two semicircle tightening pieces 3 with shaft coupling body 5, the two ends, the left and right sides of two tightening pieces 3 are processed with counterbore respectively, pressure spring 4 is installed in the counterbore, arc shaped surface adhesion around tightening piece 3 has wearing piece 2, under the effect of pressure spring 4, two tightening pieces 3 have produced the expanding force outside the axle center, fix through pin key between shaft coupling body 5 and the tightening piece 3, machine shaft is inserted in the axocoel of shaft coupling body 5, shaft coupling body 5 is fixed through axle key and machine shaft, thereby has formed the connecting structure of band buffering, and the other end of coupling 1 combines with the I axle of gearbox.The utility model under the friction effect of pressure spring 4, tightening piece 3 and wearing piece 2, drives coupling 1 and rotates when electric motor starting, thereby makes impact force obtain driving the rotation of I axle again after the buffering.
The utility model is particularly useful for the transformation and the use of C616 lathe.
Claims (2)
