After the end cover 6 is fixed, the limiting protrusion 16 of the automatic limiting mechanism 2 is positioned in the semi-annular groove 21 of the end cover 6, and meanwhile, the limiting surface of the limiting protrusion 16 is in contact with one end face of the semi-annular groove 21.
The working principle of the invention is as follows:
when the module base 1 is installed, the module base 1 is installed and positioned through the seam allowance and the speed reducer. Then install from driving wheel 3 in automatic reversing mechanism 2's switching-over recess 15, again with crescent moon board 5 and action wheel 4 dress in from driving wheel 3 inside, guarantee that crescent moon board 5 and switching-over recess 15's the thinnest department of wall thickness corresponds the installation, action wheel 4 lower extreme meshes with from driving wheel 3 this moment, the upper end contacts with crescent moon board 5, then install automatic reversing mechanism 2, action wheel 4, from driving wheel 3, the subassembly of crescent moon board 5 on the output shaft 7 of reduction gear together, automatic reversing mechanism 2 installs in the second recess 9 of module frame promptly, action wheel 4 suit is on the output shaft 7 of reduction gear. Then, the end cover 6 is installed on the module base 1, the limiting protrusion 16 is located inside the semi-annular groove 21, the limiting surface of the limiting protrusion 16 is in contact with one side end face of the semi-annular groove 21, meanwhile, the via hole of the end cover 6 is ensured to be corresponding to the internal thread hole 10 of the module base 1, and the bolt penetrates through the via hole of the end cover 6 and is in threaded connection with the internal thread hole 10 of the module base 1, so that the end cover 6 is fixed with the module base 1. And finally, the module base 1 is fixed on the speed reducer by a bolt penetrating through a through hole on the module base 1.
When the power source module is installed in the forward direction as shown in fig. 3 and the driving wheel 4 rotates clockwise, the oil suction port is below and the oil discharge port 13 is on the right side; when the driving wheel 4 rotates anticlockwise, the positions of the oil suction port and the oil discharge port are unchanged under the action of the automatic reversing mechanism 2. When the speed reducer needs to be reversely mounted, the power source module does not need to be disassembled, and the hinge bolts of the normally-mounted oil suction port 11 and the reversely-mounted oil suction port 12 can be directly replaced to realize reverse mounting.
The driving wheel 4 is arranged on the output shaft 7 of the speed reducer and drives the driven wheel 3 to rotate together. When the driving wheel 4 rotates clockwise, the cavity a 17 in fig. 3 is an oil suction cavity, the cavity B18 is an oil discharge cavity, oil reaches the cavity a 17 from an oil inlet pipeline 19 of the normally installed oil suction port 11, then the driving wheel 4 drives the driven wheel 3 to rotate together, because the driving wheel 4 is meshed with the driven wheel 3, the volume of a cavity formed between the tooth top of the driving wheel 4 and the tooth root of the driven wheel 3 is continuously changed, the volume of the cavity a 17 is continuously increased to form vacuum, the oil in the oil inlet pipeline 19 is sucked to pass through the crescent plate 5 to reach the cavity B18, and because the volume of the cavity B18 is continuously reduced to form pressure, the oil is discharged from an oil discharge pipeline 20 of the oil discharge port 13, and at this time, the power source module.
When the driving wheel 4 rotates anticlockwise, because the cavity A17 forms a sealed space, the volume of the cavity A17 is continuously reduced due to the continuous meshing of the driving wheel 4 and the driven wheel 3, the oil pressure sealed in the cavity A17 is increased, and the driven wheel 3 is pressed to rotate around the axis of the driving wheel 4. When the driven wheel 3 rotates, the friction force between the driven wheel 3 and the inner wall of the reversing groove 15 is continuously increased to drive the automatic reversing mechanism 2 to synchronously rotate together, at the moment, the limiting bulge 16 of the automatic reversing mechanism 2 slides in the semi-annular groove 21 of the end cover 6, and the crescent plate 5 also rotates together with the driven wheel 3. After the action wheel 4 rotates 180, the crescent moon board 5, from driving wheel 3, automatic reversing mechanism 2 has also rotated 180 along with, automatic reversing mechanism 2 can only stabilize at the current position after can only rotating 180 because the spacing face of the other side of its spacing arch 16 contacts spacingly with the other end terminal surface of semi-annular recess 21 of end cover 6, so crescent moon board 5 can only follow rotation 180 with from driving wheel 3, then crescent moon board 5 is in the lower extreme and no longer moves all the time, from driving wheel 3 resumes to rotate around the axis of self, A cavity 17 has rotated the right-hand member this moment, because the cavity volume of A cavity 17 increases, inside fluid can release, the inside pressure of A cavity 17 also can release. Because the crescent plate 5 is transposed from top to bottom by 180 degrees, the oil inlet is still at the left end at the moment, even if the driving wheel 4 rotates anticlockwise, the oil inlet pipeline 19 which is positively provided with the oil inlet 11 still takes oil from the left side, the oil inlet and the oil outlet do not need to be exchanged, the reverse adjustment of the speed reducer is automatically carried out, the operation is more convenient and faster, and the complicated procedure of manually exchanging oil ways is omitted.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
