[0022] The present invention provides a space-saving planetary reducer, comprising a reducer body 101, an outer shell 102, a connecting shaft 103 and a disassembly assembly, wherein the disassembly assembly comprises an output shaft body 104, a spring 105, a mounting rod 106, a limit piece and a locking piece, wherein the limit piece comprises a limit bolt 107 and a limit sleeve 108, and the locking piece comprises the locking bolt 109, a supporting rod 110, a limit sleeve 2 111 and two limit blocks 112. The above-mentioned solution solves the problem that the planetary reducer will be stacked during storage or transportation, and the output shaft of the planetary reducer is in a raised state, resulting in the planetary reducer taking up more space when stacked.

[0023] According to this specific embodiment, the outer shell 102 is fixedly connected to the reducer body 101 and is located on the outside of the reducer body 101. The connecting shaft 103 is rotatably connected to the reducer body 101 and is located in the outer shell 102. The disassembly assembly includes an output shaft body 104, a spring 105, a mounting rod 106, a limiter and a locking member. The output shaft body 104 is detachably connected to the connecting shaft 103 and is located in the connecting shaft 103. The spring 105 is fixedly connected to the output shaft body 104 and is located in the output shaft body 104. The mounting rod 106 is fixedly connected to the spring 105 and is located on the outside of the spring 105. The limiter is threadedly connected to the connecting shaft 103 and is located on the outside of the mounting rod 106. The locking piece is threadedly connected to the connecting shaft 103 and passes through the connecting shaft 103. The outer shell 102 is fixed to the outside of the reducer body 101. The connecting shaft 103 rotates in the outer shell 102 during operation. The locking piece is rotated, and the locking piece cancels the resistance to the mounting rod 106, and the locking piece is located in the connecting shaft 103. The limit piece is rotated, and the spring 105 is compressed. The limit piece resists the mounting rod 106 until the mounting rod 106 is completely located in the output shaft body 104. The output shaft body 104 is pulled outward, and the output shaft body 104 can be disengaged from the connecting shaft 103. This method can effectively solve the problem that the planetary reducer occupies more space when stacking due to the raised state of the output shaft.

[0024] Among them, the limiting bolt 107 is threadedly connected to the connecting shaft 103 and is located on the outside of the mounting rod 106. The limiting sleeve 108 is fixedly connected to the connecting shaft 103 and is located on the outside of the limiting bolt 107. The limiting sleeve 108 prevents the limiting bolt 107 from rotating out of the connecting shaft 103. The limiting bolt 107 is rotated to push the mounting rod 106 back, so that the connecting shaft 103 can cancel the clamping of the mounting rod 106.

[0025] Secondly, the locking bolt 109 is threadedly connected to the connecting shaft 103 and is located on the side of the connecting shaft 103 away from the limiting bolt 107. The supporting rod 110 is fixedly connected to the locking bolt 109 and is located on the outside of the locking bolt 109, and the supporting rod 110 passes through the connecting shaft 103. When the mounting rod 106 is engaged with the connecting shaft 103, the locking bolt 109 is rotated, and the locking bolt 109 pushes the supporting rod 110 to support the mounting rod 106, thereby fixing the mounting rod 106. When the mounting rod 106 needs to be removed, the locking bolt 109 is rotated in the opposite direction to cancel the support of the supporting rod 110 on the mounting rod 106.

[0026] At the same time, the second limiting sleeve 111 is fixedly connected to the connecting shaft 103 and is located on the outside of the locking bolt 109. The mounting rod 106 has a sliding groove 113 adapted to the limiting block 112. The two limiting blocks 112 are fixedly connected to the output shaft body 104 and are located in the sliding groove 113. The second limiting sleeve 111 prevents the locking bolt 109 from rotating out of the connecting shaft 103. The limiting block 112 slides in the sliding groove 113 of the mounting rod 106. The limiting block 112 prevents the mounting rod 106 from separating from the output shaft body 104.

[0027] In addition, the outer shell 102 has a through groove 114, and the output shaft body 104 has a locking groove 115 adapted to the supporting rod 110. The through groove 114 facilitates the adjustment of the limit bolt 107 and the locking bolt 109. The supporting rod 110 passes through the output shaft body 104 through the locking groove 115 and supports the mounting rod 106.

[0028] A space-saving planetary reducer using this embodiment is provided with the outer shell 102, the connecting shaft 103 and the disassembly assembly. When it is used, the outer shell 102 is fixed to the outside of the reducer body 101, and the locking bolt 109 is rotated. The locking bolt 109 drives the supporting rod 110 to move outward, and the supporting rod 110 cancels the support to the mounting rod 106. The limiting sleeve 111 prevents the locking bolt 109 from rotating out of the connecting shaft 103, and the limiting bolt 107 is rotated. The limiting bolt 107 pushes the mounting rod 106 back into the output shaft body 104, and the spring 105 is compressed, pulling the output shaft outward. The output shaft body 104 can be disengaged from the connecting shaft 103. After disengagement, the spring 105 retracts, and the limiting block 112 prevents the mounting rod 106 from being disengaged from the output shaft body 104, thereby separating the output shaft from the reducer body 101. When installation is required, the output shaft body 104 can be clamped to the connecting shaft 103 by pressing the mounting rod 106, and the output shaft body 104 can be fixed by rotating the limiting bolt 107 and the locking bolt 109. In this way, the output end of the planetary reducer can be disassembled, thereby facilitating the placement of the planetary reducer, effectively saving the space occupied by the planetary reducer when stacked, and improving the utilization rate of the storage space.

[0029] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the utility model.
