Technical Field
[0001] This utility model relates to the field of speed reducer technology, and more specifically to a vertical speed reducer. Background Technology
[0002] A speed reducer has a speed reduction mechanism that slows down the speed of the prime mover and smoothly transmits power to the mechanical equipment through the output shaft of the speed reduction mechanism. The speed reduction mechanism can include transmission methods such as worm gear transmission, gear transmission or planetary transmission.
[0003] As the name suggests, a vertical speed reducer is fixed in a vertical installation manner, which is used for heavy-duty work to ensure that the equipment can output stably and at a constant speed for a long time. The speed reducer consists of a prime mover and a speed reduction transmission device, which are usually fixed together by bolts. Under high-frequency and high-load operation, the gears in the speed reduction transmission device are prone to grinding and making abnormal noises, so it is necessary to disassemble and inspect the internal parts. However, the bolt connection method requires a lot of time to disassemble and assemble, and is not easy to remove, which will affect the maintenance efficiency of the speed reducer.

[0030] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.
[0031] like Figure 1-6 As shown, a vertical speed reducer includes:
[0032] A driving element 1 is provided with a first end 11, and an arc-shaped groove 14 is provided on the first end 11 in a circular array.
[0033] The speed reduction device 3 has a second end 31.
[0034] Connector 2 is disposed on the second end 31. Connector 2 includes a support frame 27, a fixed plate 23 and a locking rod 21 threadedly connected to the fixed plate 23. The support frame 27 is slidably disposed on the fixed plate 23.
[0035] A locking block 24 is slidably mounted on the support frame 27. A top block 25 that pushes against the locking block 24 is provided at the end of the locking rod 21. The locking rod 21 rotates on the fixed plate 23 so that the top block 25 pushes the locking block 24 to slide outward on the support frame 27, so that the end face of the locking block 24 abuts against the arc groove 14.
[0036] Specifically, the driving element 1 is a motor, while the reduction device 3 can be a worm gear, helical gear reduction transmission, or other reduction mechanism. When the two are assembled, the output shaft of the driving element 1 is inserted and snapped into the reduction device 3 so that the first end 11 and the second end 31 are in contact. At this time, the connecting piece 2 is located in the arc groove 14. Then, the reduction device 3 slides relative to the driving element 1 so that the support frame 27 slides in the arc groove 14 so that the locking block 24 slides into the triangular locking groove 141. At this time, under the elastic pull of the second spring 28, the support frame 27 is always in contact with the stop edge 142 of the arc groove 14 so that the driving element 1 and the reduction device 3 are pre-fixed. Then, the locking rod 21 is rotated, and during the sliding process of the top block 25, the upper end surface of the support frame 27 is in contact with the stop edge 142. The top block 25, located on the support frame 27, slides axially against the two locking blocks 24, which slide towards each other until the second inclined surface 243 of the locking block 24 fits into the triangular groove 141, thus providing radial fixation. This completes the assembly of the reduction gear 3 and the prime mover 1. The axial and radial fixation are based on the axis of the locking rod 21. Conversely, when the reduction gear 3 or the prime mover 1 is damaged, the locking rod 21 can be rotated to separate the locking block 24 from the triangular groove 141, and then the reduction gear 3 can be rotated in the opposite direction relative to the prime mover 1 to separate the reduction gear 3 and the prime mover 1. Compared with the bolt connection method, the connection method of this application does not require tools and can quickly disassemble the reduction gear 3 and the prime mover 1, thereby improving the efficiency of disassembling and assembling the vertical reducer.
[0037] As a further embodiment provided by this utility model, the locking rod 21 is provided with a threaded portion 22 and a smooth portion 211. The threaded portion 22 is threadedly connected to the fixed plate 23, and the top block 25 is provided on the smooth portion 211. The locking blocks 24 are two sets that slide within the support frame 27. Both locking blocks 24 abut against the top block 25. The fixed plate 23 is engaged with the second end 31 to support the rotation of the locking rod 21. When the locking rod 21 is located in the arc groove 14, the locking rod 21 rotates. Since the locking rod 21 is threadedly connected to the fixed plate 23, the top block 25 moves along the axial direction of the locking rod 21 to push the two locking blocks 24 to slide relative to each other until the locking blocks 24 contact the triangular groove 141. The smooth portion 211 and the top block 25 are rotatably connected.
[0038] As a further embodiment of this utility model, the locking block 24 is provided with a first inclined surface 242, and the top block 25 is provided with a third inclined surface 251 that abuts against the first inclined surface 242. Under the restriction of the first inclined surface 242 and the third inclined surface 251, when the top block 25 slides upward, the third inclined surface 251 can push against the first inclined surface 242, so that the two locking blocks 24 slide towards each other.
[0039] As a further embodiment of this utility model, the support frame 27 is provided with a guide groove 271, the locking block 24 slides in the guide groove 271, and a first spring 26 is provided between the two locking blocks 24. The guide groove 271 serves as a limit to restrict the sliding direction of the two locking blocks 24. In the initial state, the pull back of the first spring 26 is used to keep the two locking blocks 24 always in contact with the third inclined surface 251 of the top block 25. Furthermore, an installation groove 241 is provided on the locking block 24, and the first spring 26 is fixed in the installation groove 241.
[0040] As a further embodiment of this utility model, a groove is provided on the fixed plate 23, and a second spring 28 is provided in the groove to push the support frame 27. The elastic pull force of the second spring 28 is such that when the connector 2 is placed in the arc groove 14, the support frame 27 abuts against the edge 142 by the pull of the second spring 28, so as to achieve the effect of pre-fixing.
[0041] As a further embodiment of this utility model, a limiting block 231 is provided in the slide groove, the limiting block 231 abuts against the support frame 27, and the limiting block 231 restricts the sliding distance of the support frame 27 in the fixed plate 23.
[0042] As a further embodiment provided by this utility model, a triangular slot 141 is provided in the arc-shaped groove 14, and a second inclined surface 243 is provided on the locking block 24. The second inclined surface 243 cooperates with the triangular slot 141. The triangular slot 141 and the second inclined surface 243 of the locking block 24 increase the contact area between the locking rod 21 and the arc-shaped groove 14, thereby improving the connection effect between the prime mover 1 and the deceleration device 3.
[0043] As a further embodiment provided by this utility model, the number of arc-shaped grooves 14 and connecting members 2 is the same, and at least three sets of arc-shaped grooves 14 and connecting members 2 are provided. The more connecting members 2 and arc-shaped grooves 14 there are, the more connection support points there are for the prime mover 1 and the deceleration device 3, and the more firmly they are fixed.
[0044] As a further embodiment of this utility model, a first rubber ring 12 and a second rubber ring 13 are respectively provided on the first end 11, and an arc groove 14 is located between the first rubber ring 12 and the second rubber ring 13. A first sealing block 32 and a second sealing block 33 are respectively provided on the second end 31. The first sealing block 32 engages with the second rubber ring 13, and the second sealing block 33 engages with the first rubber ring 12. The first rubber ring 12 and the second rubber ring 13 improve the connection sealing between the prime mover 1 and the deceleration device 3, so as to ensure that impurities will not enter from the connection between the prime mover 1 and the deceleration device 3.
[0045] As a further embodiment provided by this utility model, the first rubber ring 12 is provided with a protrusion 121 that abuts against the second sealing block 33, and the second rubber ring 13 is provided with a groove 131 that abuts against the first sealing block 32. The protrusion 121 and the groove 131 increase the contact area between the second sealing block 33 and the first sealing block 32, thereby further improving the sealing effect of the prime mover 1 and the deceleration device 3.
