Abstract
The invention relates to a coupling structure for a rolling frame. The coupling structure for the rolling frame is used for solving the problem of inconvenience in connecting the coupler and rolling mechanism in the prior art, effectively prolonging the service life of an output shaft of a speed reducer and lowering the maintenance cost. The coupling structure comprises an inner gear ring, a transmission gear and the output shaft of the speed reducer, wherein the inner gear ring is pressed in a shell through an end pressing ring; a gear end of the transmission gear is axially inserted into the shell, is meshed and connected with teeth of the inner gear ring and is fixedly connected with the shell through a bolt; the transmission gear is axially connected with the output shaft of the speed reducer; the coupling structure is characterized in that a mounting hole is formed at the gear end of the transmission gear along an axis; a spring is mounted in the mounting hole; a stair blocking slot is arranged on an inner peripheral wall between inner teeth surfaces at two ends of the inner gear ring; a spring gland is mounted in the stair blocking slot; an axial lug boss is arranged on the spring gland; the lug boss is sleeved at one end of the spring; and the other end of the spring is limited by the bottom surface of the mounting hole.
Description
Technical field
The present invention relates to the processing unit (plant) field of seamless steel pipe, be specially the coupling structure of rolling machine frame.
Background technology
In the continuous seepage of China's seamless steel pipe manufactures, change the manufacturing rhythm of rolling machine frame to whole line in time, rapidly of crucial importance, even had influence on and produced the output of pipe, the cost of the manufacturing.Existing rolling machine frame shaft coupling, its one end is connected with rolling machine frame gear by ring gear, the other end is connected with speed reducer output shaft by travelling gear, between ring gear and travelling gear, profile of tooth is connected with a joggle, need during installation first the profile of tooth of the ring gear of rolling machine frame tooth-formation of gear and shaft coupling to be adjusted in same angle just can engage each other, it installs inconvenience, and it is low that rolling mill changes efficiency; And existing shaft coupling is connected with a joggle by the internal spline of its travelling gear and the external splines of output shaft, in use inside and outside spline very easily corrosive wear, and interior external splines binding site adds lubricant difficulty, makes it lubricate insufficient, reduce output shaft service life; In addition, the inside and outside spline joint between shaft coupling transmission gear and speed reducer output shaft, also increases the difficulty changing output shaft, reductor need be unpacked during replacing, and Renewal process needs 10 to 15 people to spend 100 hours just can complete, and maintenance cost is high.
Summary of the invention
The present invention is directed to the coupling structure that the problems referred to above provide rolling machine frame, it can solve existing shaft coupling is connected inconvenience problem with rolling machine frame, and can service life of effective prolonged deceleration machine output shaft, reduction maintenance cost.
Its technical scheme is such, it comprises ring gear, travelling gear, speed reducer output shaft, described ring gear press-fits in shell by end pressure ring, be connected with a joggle with described ring gear flute profile after the described shell of the axial insertion of gear end of described travelling gear, and be connected and fixed by bolt and described shell, described travelling gear is axially connected with described speed reducer output shaft, it is characterized in that: the gear end of described travelling gear has installing hole along axis, in described installing hole, spring is installed, between the two ends inner toothed surface of described ring gear, inner peripheral surface is provided with step draw-in groove, in described step draw-in groove, spring capping is installed, described spring capping is provided with axial boss, described spring one end is set in described boss, the other end is spacing by described installing hole bottom surface.
It is further characterized in that:
Described speed reducer output shaft is optical axis, and its end sleeve is loaded in axle sleeve, and described axle sleeve is connected with described travelling gear straight end-face key;
Axis hole interference fit between described axle sleeve with described speed reducer output shaft and between described axle sleeve with described speed reducer output shaft key be connected;
Described axle sleeve and described speed reducer output shaft are by end cap and bolt axial location;
The flank of tooth of described travelling gear is drum-shaped tooth.
After adopting the present invention, its beneficial effect is: shaft coupling is after contacting with rolling machine frame, only reductor need be rotated, under the elastic telescopic effect of spring, shaft coupling ring gear will engage each other with frame barreled tooth flank automatically and quickly, make assembling process simple and convenient, greatly improve the replacing efficiency of rolling machine frame; Output shaft is with axle sleeve interference fit and key is connected, axle sleeve is connected with travelling gear straight end-face key, make output shaft can better transmitting torque, lubrication is convenient and more abundant, thus the service life of output shaft can be extended, and the mounting structure of output shaft is simple, facilitate maintenance and the replacing of output shaft, reduce maintenance cost, axle sleeve is connected with travelling gear straight end-face key; Output shaft is fixed by end cap, prevents output shaft rotation from producing axial dipole field, avoids axle sleeve to come off; Axle sleeve is connected with gear key, decreases bolt bears axial tension, axial alternating bending situation at connecting portion, makes the connection of output shaft and rolling machine frame more safe and reliable; The flank of tooth of travelling gear is drum-shaped tooth, makes ring gear have the pivot angle of certain angle in radial direction, facilitates gear insert ring gear and engage with ring gear profile of tooth.
