Embodiment
For innovation and creation content, the Characteristic of the invention can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As depicted in figs. 1 and 2, the test unit that a kind of final drive shaft and auxiliary transmission shaft link, comprise protective cover 1, protective cover is made up of fixed enclosure and unlatching cover body, open rolling bearing on cover body and hand wheel shaft 6 is installed, hand wheel shaft is arranged along the radial direction of protective cover, the outer end of hand wheel shaft is provided with handwheel 7, the inner of hand wheel shaft is installed with conical gear second 8, unlatching cover body goes back rolling bearing screw mandrel 3 is installed, the axis being parallel of the axis of screw mandrel and final drive shaft and auxiliary transmission shaft, one end of screw mandrel is installed with conical gear first 5, screw mandrel is vertical with hand wheel shaft, conical gear first engages with conical gear second, screw mandrel is provided with shift fork 9, shift fork comprises the screw 19 be connected with wire rod thread, be sleeved on sliding set 21 outside rolling bearing first one side and be connected sliding set, the fork plate 20 of screw, fork plate is also sleeved on the guide pole 4 parallel with screw mandrel, the support body that what guide pole was fixed be arranged on for supporting screw mandrel.
Rolling bearing second 13 is sleeved on sliding sleeve 14, rolling bearing second is blocked by the circlip for shaft on sliding sleeve, large spline housing 16 is provided with in sliding sleeve, little spline housing 15 is provided with in large spline housing, the inner side of large spline housing and final drive shaft 18 spline joint, auxiliary transmission shaft 17 is provided with inside final drive shaft, large spline housing is provided with the spline coordinated with large spline sleeve, radial direction along sliding sleeve on sliding sleeve is provided with through hole, be installed with adjusting bolt 2 in through hole, adjusting bolt is threaded with the threaded hole arranged along little spline housing radial direction.
As shown in figures 1 and 3, also rolled by rolling bearing first 12 in large spline housing and be provided with top 11, be toply contained on large spline housing 16, top point withstands on auxiliary transmission shaft.
The operating principle of the invention is:
Rotate handwheel 7, drive hand wheel shaft 6 to rotate, the conical gear second 8 of hand wheel shaft medial end drives conical gear first 5 to rotate, and conical gear second drives screw mandrel to rotate.Because the fork plate of shift fork is sleeved on guide pole 4, so the guide effect of guide pole causes shift fork not rotate, the screw part of shift fork and screw mandrel relatively rotate, so shift fork does rectilinear motion on screw mandrel.Sliding set due to shift fork is on the outer ring being sleeved on rolling bearing second 13 partly, and rolling bearing second is blocked by the circlip for shaft on sliding sleeve, so drive sliding sleeve 14 to slide by rolling bearing second.
Because the adjusting bolt be through on the through hole of sliding sleeve is also threaded with the threaded hole on little spline housing, so when sliding sleeve slides time, the slip of sliding sleeve also can drive the slip of little spline housing 15.So when shift fork is positioned at the left side of Fig. 1, time little spline housing is sleeved on auxiliary rotation axis 17, by final drive shaft → large spline housing → adjusting bolt → little spline housing → this drive path of auxiliary transmission shaft, auxiliary transmission shaft just can be enable to rotate with same speed with final drive shaft.When shift fork is positioned at the right side of Fig. 1, time little spline housing would not be sleeved on the outside of auxiliary transmission shaft, above-mentioned driving chain is interrupted, and the rotation of final drive shaft would not change into the rotation of auxiliary transmission shaft.So this test unit achieves the free break-make of little spline housing and auxiliary transmission shaft, also just achieve the requirement that main and auxiliary transmission shaft links at any time.
In addition, adjusting bolt not only can realize the connection of sliding sleeve and little spline housing, the many adjusting bolts be arranged on sliding sleeve can also be utilized, by regulating screw thread to be screwed at little spline housing upper screwed hole the axial location that the degree of depth adjusts little spline housing, thus ensure that the right alignment between little spline housing, large spline housing.
Although be described the preferred embodiment of the invention by reference to the accompanying drawings above; but the invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of the invention; do not departing under the ambit that the invention aim and claim protect, can also make a lot of form, these all belong within the protection domain of the invention.
