Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, a detachable parallel-stage wind power generation main gearbox 10 includes: a planetary stage 11 and a parallel stage 12. The planetary stage 11 drives the parallel stage 12 to output power through the parallel stage 12.
The planetary stage 11 comprises: ring gear 113. The parallel stage 12 includes: high-speed shafting, spline shafting 14, hollow shaft 146, upper box body 15, lower box body 16 and back box body 17. The rear case 17 is attached to the ring gear 113. The upper case 15 and the lower case 16 are mounted to the rear case 17. The upper casing 15, the lower casing 16 and the rear casing 17 form an installation space after installation. The high speed shafting, the spline shafting 14 and portions of the tube shaft 146 are located within this mounting space.
As one solution, the rear case 17 is detachably attached to the ring gear 113 in the axial direction of the tube shaft 146. The upper casing 15 and the lower casing 16 are detachably mounted to the rear casing 17 in directions perpendicular to the axis of the tube shaft 146, respectively. When the upper casing 15 is mounted, the upper casing 15 may be moved in a direction parallel to the axis of the pipe shaft 146 to bring the upper casing 15 close to the rear casing 17, and then the upper casing 15 may be mounted to the rear casing 17 by moving the upper casing 15 downward in a direction perpendicular to the axis of the pipe shaft 146. Also, when mounting the lower case 16, it is possible to first move the lower case 16 in a direction parallel to the axis of the tube shaft 146 to bring the lower case 16 close to the rear case 17, and then move the lower case 16 upward in a direction perpendicular to the axis of the tube shaft 146 to mount the lower case 16 to the rear case 17. When a problem occurs in the low-speed gear 145, the sun gear shaft 141, or the spline shaft 147 in the parallel stage 12 of the detachable parallel-stage wind-power-generating main gear box 10, it can be detached for maintenance. The upper casing 15 and the lower casing 16 are detached from the rear casing 17 in the direction perpendicular to the axis of the tube shaft 146, respectively, so that the structure in the installation space can be maintained. When the low-speed gear 145, the sun gear shaft 141, or the spline shaft 147 is removed, the total height of the upper case 15 and the lower case 16 separated from each other needs to be larger than the diameter of the low-speed gear 145, so that the spline shaft system 14 is not restricted in the vertical direction, thereby satisfying the condition that the spline shaft system 14 can be moved in the axial direction. The spline shaft system 14 is moved out in the axial direction and the corresponding structure is disassembled for maintenance.
The spline shaft system 14 further includes: a sun gear shaft 141, a spline shaft 147, and a low-speed gear 145. The spline shaft 147 is connected to the low-speed gear 145.

The sun gear shaft 141 is an ISS sun gear.
Specifically, the planet stage 11 transfers input power to the parallel stage 12 through the sun gear 1421 of the first connecting shaft 142. In the parallel stage 12, the first connecting shaft 142 transmits the input power to the low-speed gear 145 through the second connecting shaft 143. Low-speed gear 145 in turn drives the high-speed shafting to achieve power output. The low-speed gear 145 is sleeved on the outer periphery of the second connecting shaft 143, and the low-speed gear 145 and the spline 1431 are located in the installation space.

Based on the above, when the gear structure in the parallel stage 12 is in problem, the upper casing 15 and the lower casing 16 are disassembled in the direction perpendicular to the axial direction, and then the second tube shaft 1462 is disassembled from the first tube shaft 1461. The required axial space of maintenance can be shortened like this, and it is less to avoid appearing the cabin interior space, and hollow shaft 146 length is longer, can't dismantle the problem of maintenance in the cabin. At this time, the low-speed gear 145 or the spline shaft 147 can be removed for maintenance.
If the first connecting shaft 1421 of the sun gear shaft 141 is to be repaired, the second connecting shaft 143 and the first connecting shaft 142 may be detached first to shorten the length of the sun gear shaft 141, so as to reduce the axial space required for detaching the sun gear shaft 141, thereby avoiding the problem that the space in the engine room is small, and the sun gear shaft 141 is long and cannot be detached and repaired in the engine room. The first connecting shaft 142 can now be removed to service the sun gear shaft 141.
As a preferred embodiment, the planetary stage 11 comprises: a first planetary stage 111 and a second planetary stage 112. The first planetary stage 111 drives the parallel stage 12 via the second planetary stage 112.
