Description

Technical Field

[0001] This utility model belongs to the field of planetary reducer technology, and in particular relates to a two-stage planetary reducer that is easy to hoist. Background Technology

[0002] Planetary gear reducers are industrial power transmission mechanisms characterized by their compact structure, small size, smooth operation, and low noise. They are widely used in various mechanical transmission systems, and their main transmission structure includes planetary gears, a sun gear, and an external gear ring.

[0003] The planetary gear reducers currently on the market have the following problems when used:

[0004] 1. Traditional planetary gear reducers are typically hoisted using lifting rings on the gear reducer. Since the lifting rings are usually fixed to the gear reducer, they are difficult to remove when not hoisting, making them quite space-consuming to use.

[0005] 2. When a traditional planetary gear reducer is placed, there is a seam between the reducer shaft and the housing. When it needs to be placed for a long time, dust, impurities, water and other substances in the air can easily enter the interior of the reducer through the seam, resulting in poor protection. Utility Model Content

[0006] The purpose of this utility model is to provide a two-stage planetary reducer that is easy to hoist, so as to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A two-stage planetary reducer that is easy to hoist includes a reducer body, a first mounting ring sleeved on the outside of the reducer body, a second mounting ring sleeved on the outside of the reducer body, a fixing seat fixedly connected to the sides of the first and second mounting rings, a lifting ring fixedly connected to the surface of the fixing seat, a first mounting plate fixedly connected to the surface of the first mounting ring, and two first mounting plates are provided; a second mounting plate fixedly connected to the surface of the second mounting ring, and two second mounting plates are provided.

[0008] Preferably, a first protective cover is fitted onto the top of the reducer body, a second protective cover is fitted onto the top of the reducer body, a top plate is fixedly connected to the top of the reducer body, a rotating block is fixedly connected to the surface of the top plate, a rotating plate is fitted onto the outside of the rotating block, a first fixed block is fitted onto the outside of the first protective cover, a second fixed block is fitted onto the outside of the second protective cover, and sealing gaskets are embedded on the sides of the first and second protective covers.

[0009] Preferably, an internal threaded seat is fixedly connected to the surface of the first mounting plate, a threaded rod passes through the internal threaded seat, and a turntable is fixedly connected to the surface of the threaded rod.

[0010] Preferably, the rotating plate has two butterfly bolts running through it.

[0011] Preferably, a card block is fixedly connected to the surface of the first fixing block, and a card slot is formed on the surface of the second fixing block, with the card block embedded inside the card slot.

[0012] Preferably, the first protective cover is fixedly connected to the side of the insert plate, and the second protective cover has a slot on its side, into which the insert plate is inserted.

[0013] The two-stage planetary reducer of this utility model, which is easy to hoist, has the following advantages:

[0014] 1. This convenient two-stage planetary reducer is characterized by a first mounting ring and a second mounting ring fitted onto the outside of the reducer body. Fixed seats are mounted on the sides of the first and second mounting rings, and lifting rings are mounted on the surfaces of the fixed seats. A first mounting plate is mounted on the surface of the first mounting ring, and a second mounting plate is mounted on the surface of the second mounting ring. When the planetary reducer needs to be lifted, the first and second mounting rings are first installed on the outside of the reducer body, and then fixed using the first and second mounting plates. The reducer body can then be lifted using the lifting rings. After lifting, the first and second mounting rings can be directly removed to remove the lifting rings, thus saving space.

[0015] 2. This convenient two-stage planetary reducer is characterized by a first protective cover fitted onto the top of the reducer body, a second protective cover fitted onto the top of the reducer body, a top plate mounted on the top of the reducer body, a rotating block mounted on the surface of the top plate, a rotating plate fitted onto the outside of the rotating block, a first fixing block fitted onto the outside of the first protective cover, a second fixing block fitted onto the outside of the second protective cover, and sealing gaskets embedded on the sides of the first and second protective covers. When the reducer body is not in use, the first and second protective covers are simply fitted onto the connection between the shaft and the housing, and fixed by the first and second fixing blocks. Then, the rotating plate is rotated so that it presses against the first and second protective covers, thus fixing the rotating plate. At this time, the sealing gaskets can play a sealing role, preventing impurities from entering the joint between the shaft and the housing, thus improving the protective effect.
