Abstract
The utility model discloses a spline reducing expanded shaft, which comprises a multi-step shaft. The outer wall of the minor diameter segment of the multi-step shaft is provided with an external spline. The multi-step shaft is provided with an axial through hole the middle part of which is provided with a circular step. The inner wall of the through hole at the major diameter segment of the multi-step shaft is provided with an internal spline. The utility model makes a yawing reducer have good interchangeability, low cost and good effectiveness and reliability through the design when moment is transmitted.
Description
Technical field
The utility model relates to a kind of power transmitting deice, especially the spline reducing spreading axle in yawing speed reducer power output procedure.
Background technique
Often directly be connected between the output shaft of yawing speed reducer and the load at present, keyway is set respectively between output shaft and load, cooperate the effect of playing carry-over moment by key with both keyways again by key.So have three shortcomings at least: the one, every kind of output shaft can only cooperate a kind of load device, when needs are changed another load device, must change the output shaft that matches, so interchangeability is poor; The 2nd, under the situation that some vibrate comparatively seriously or the suffered axial force of load is bigger, move axially easily between load and the output shaft, may cause transmission failure or transmission between output shaft and the load unreliable; The 3rd, self contering is poor, and transmission is not steady, the radial force inequality.
The model utility content
Technical problem to be solved in the utility model is to provide the reducing spreading axle that a kind of interchangeability is good, connection utilizes spline to connect reliably.
The technical solution of the utility model is as follows: design a kind of spline reducing spreading axle, it comprises the step axle, and its main points are: be provided with external splines on described step axle path section outer wall; On described step axle, be provided with axial hole, be provided with ring-shaped step, be provided with internal spline at the through-hole wall that is positioned at the big footpath of described step axle section at this axial hole middle part; The through hole that is positioned at described step axle path section is equipped with special-shaped pressing plate, and described special-shaped pressing plate is axially arranged with the sunk screw hole.The utility model is connected the transmission of carrying out moment between yawing speed reducer output shaft and the load device, the output terminal of yawing speed reducer output shaft stretches in the through hole of the big footpath of step axle section, connect by internal spline, because the axial hole middle part is provided with ring-shaped step, therefore the yawing speed reducer output shaft end is against on the ring-shaped step, at the through hole that is positioned at described step axle path section the special-shaped pressing plate that is axially arranged with the sunk screw hole is housed then, this abnormal shape pressing plate the inner be against the other end of ring-shaped step on, by screw yawing speed reducer output shaft and special-shaped pressing plate are locked at last, can prevent effectively that so the utility model from moving axially on the yawing speed reducer output shaft; Be sleeved on deceleration loading device on the path section of step axle by external splines, so just can realize effective transmission of moment, the utility model can design according to the difference of the yawing speed reducer output shaft diameter of axle and the difference of deceleration loading device attachment hole like this, has strengthened the interchangeability between the transmission device in the gear transmission process.
Described external splines and internal spline are involute splines.Involute is the spline that processes with gear working method, and the likeness in form gear has big and each tooth of bearing capacity to be evenly distributed than rectangular spline.
Beneficial effect: 1. interchangeability is good, and cost is low; 2. transmission of torque is effectively reliable; 3. self contering precision height.
Description of drawings
Fig. 1 is user mode figure of the present utility model;
Fig. 2 is a structural representation of the present utility model.
Meaning of each numbering is in the above-mentioned accompanying drawing: 1. step axle, 2. external splines, 3. ring-shaped step, 4. internal spline, 5. special-shaped pressing plate, 6. yawing speed reducer, 7. output shaft, 8. screw.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
See also Fig. 1 and Fig. 2: shown in spline reducing spreading axle, form by step axle 1, internal spline 4, external splines 2, on described step axle 1 path section outer wall, be provided with external splines 2; On described step axle 1, be provided with axial hole, be provided with ring-shaped step 3 at this axial hole middle part, be provided with internal spline 4 at the through-hole wall that is positioned at described step axle 1 big footpath section, described step axle 1 big footpath section is sleeved on the output shaft 7 of yawing speed reducer 6 by internal spline 4, at the through hole that is positioned at described step axle 1 path section special-shaped pressing plate 5 is housed then, described special-shaped pressing plate 5 is axially arranged with the sunk screw hole, the screw 8 of in described sunk screw hole, packing into, described screw 8 front ends pierce the front end of output shaft 7, and with output shaft 7 lockings, prevent that so step axle 1 from moving axially on output shaft 7, at last in the path section of step axle 1 by the external splines 2 suits connection load device that cogs.
See also Fig. 2: described external splines 2 and internal spline 4 are involute splines.
